Installing zend framework on wamp

2011-01-03T01:21:00.000-08:00

Version Information:

WampServer 2.0i [07/11/09]
Includes :
- Apache 2.2.11
- MySQL 5.1.36
- PHP 5.3.0

Zend Framework 1.10.3

OS: windows xp sp3

Directory Structure:

c:\wamp\(out of the box wamp 2.0 structure)
c:\zend\(out of the box zend framework 1.10.3 structure)
C:\zendSites\(this is the folder i created to hold my zend projects)

-----------------------

Error 1 occurred while trying to create my project from the command prompt.
This error occurrs becuase windows does not know where to look for zf.bat.

C:\zendSites>zf create project quickstart
'zf' is not recognized as an internal or external command, operable program or batch file.

action: add the zf.bat path to windows xp environment variables...
right click mycomputer>>properties>>advanced>>environment variables>>
then highlight "path" in the list of system variables and click edit
in my case i added ";c:\zend\bin" (without quotes) to the end of the list
note that the leading semicolen is the path separator.
restart computer.

--------------------

Error 2 occurred while trying to create my project from the command prompt and after adding the zf.bat path to windows environment variables. This error occurrs because windows does not know how to execute php scripts. It needs to know the path to php.exe

C:\zendSites>zf create project quickstart
'"php.exe"' is not recognized as an internal or external command,
operable program or batch file.

action: add the php.exe path to the windows environment variables.
same as above, but this time i'm adding the path ;C:\wamp\bin\php\php5.3.0
don't forget to restart your computer

--------------------

Expanded explanation of creating a virtual host on windows running wamp server 2.0

open httpd.conf (click on the wamp icon in the services>>apache>>httpd.conf)
find and uncomment the line: #Include conf/extra/httpd-vhosts.conf by removing the # sign go to C:\wamp\bin\apache\Apache2.2.11\conf\extra\ and open httpd-vhosts.conf note the "Apache2.2.11" in the above path. obviously this is version specific.

add the following block of code to the end of httpd-vhosts.conf...

DocumentRoot "c:\zendSites\quickstart\public"
ServerName quickstart.local
SetEnv APPLICATION_ENV "development"

DirectoryIndex index.php
AllowOverride All
Order allow,deny
Allow from all

DocumentRoot C:\wamp\www
ServerName localhost

...after adding this block of code you will need to update your windows hosts file, which maps requested urls to the server. go to C:\WINDOWS\system32\drivers\etc and open the hosts file. add the following 2 lines to the bottom of the file...

127.0.0.1 localhost
127.0.0.1 quickstart.local

...now restart your wamp server.

notice the entries for localhost. this is to preserve localhost paths like that for phpmyadmin
note, that now you have done this your address will be quickstart.local so any reference in the tutorial that says to go to http://localhost should be replaced now by http://quickstart.local
this page will not be found by requests outside the local computer. ie. you will not be online until you register with a DNS (beyond the scope of this material)

-------------------------

Error 3
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

after making the changes above you will likely get this error In this case the error is caused becuase appache does not have the rewrite module enabled
action:
click on the wamp server icon in the services portion of the windows task bar.
apache>>apache modules>>scroll down to "rewrite_module" and click it.
wamp should restart automatically

----------------------------

Error 4
Warning: require_once(Zend/Application.php) [function.require-once]: failed to open stream: No such file or directory in C:\zendSites\quickstart\public\index.php on line 18
Fatal error: require_once() [function.require]: Failed opening required 'Zend/Application.php' (include_path='C:\zendSites\quickstart\library;.;C:\php5\pear') in C:\zendSites\quickstart\public\index.php on line 18

at this point if you have not set your include_path in php.ini you will recieve the above error.

action:
click the wamp server icon in the services section of the windows taskbar>>php>>php.ini
now change the following section...

; Windows: "\path1;\path2"
; include_path = ".;c:\php\includes"

to...

; Windows: "\path1;\path2"
include_path = ".;c:\php\includes;c:\zend\library"

...and restart the wamp server again

-----------------------------
Error 5
'dbname' is not recognized as an internal or external command,
operable program or batch file.

cmd input/output:
C:\zendSites\quickstart>zf configure db-adapter 'adapter=PDO_SQLITE&dbname=APPLICATION_PATH "/../data/db/guestbook.db"' production
A db configuration for the production section has been written to the application config file.
'dbname' is not recognized as an internal or external command,
operable program or batch file.

this has to do with the difference between how linux and windows systems intrepret quotation marks.
so you will need to change...

zf configure db-adapter 'adapter=PDO_SQLITE&dbname=APPLICATION_PATH "/../data/db/guestbook.db"' production

to...

zf configure db-adapter "adapter=PDO_SQLITE&dbname=APPLICATION_PATH '/../data/db/guestbook.db'" production

--------------------------------

when creating load.sqlite.php, data.sqlite, schema.sqlite.sql make sure that the scripts folder that holds them is at the same level as the application folder. ie. c:\zendSites\quickstart\scripts
also make sure that the load.sqlite.php code from framework.zend.com is enclosed with the php tags (). when you run this script from the prompt make sure you run it from the quickstart path

--------------------------------

Error 6
C:\zendSites\quickstart>php scripts\load.sqlite.php --withdata
PHP Warning: require_once(Zend/Loader/Autoloader.php): failed to open stream: No such file or directory in C:\zendSites\quickstart\scripts\load.sqlite.php

this was a tricky one. It occurrs when we try to run the load.sqlite.php script because the command prompt uses a different php.ini than apache. you need to navigate to...

C:\wamp\bin\php\php5.3.0\php.ini

now change the following section...

; Windows: "\path1;\path2"
; include_path = ".;c:\php\includes"

to...

; Windows: "\path1;\path2"
include_path = ".;c:\php\includes;c:\zend\library"

...and restart the wamp server again

------------------------------------

after working through all the above issues my quickstart application worked.

Good Luck!

Indexing in database

2010-12-17T23:10:00.000-08:00

An index is a separate file that is sorted, and contains only the field/s you're interested in sorting on. If you create an index on employee_number, MySQL can find the corresponding record very quickly (Indexes work in very similar ways to an index in a book. Imagine paging through a technical book (or more often, an scrambled pile of notes!) looking for the topic "Optimizing MySQL". An index saves you an immense amount of time!

Css Learning

2010-11-24T22:41:00.000-08:00

white-space:no-wrap to make text in a line .
vertical-align:middle; display:table-cell will not work with float so advise to insert a div cover for entering float .
Use Float left to all the div in the container with the width specified.
Use Position:relative for parent div , and absolute for child div for positioning.
For Floating image use overflow:hidden;
Use CSS selectors .e.g. > * for select adjacent child divs. Check this link for more css selectors.
Z-index of elements should be check in the same Containers., And position should be absolute of the other element.

Best Coding Practices

2010-11-16T23:35:00.000-08:00

The more code you have the more possible to make errors and the more code you have to maintain.
Use Plugins are around to make life easier after all to write less code
Never write html code in the js files , always put html code in html file , and access html element in jquery .
Object Oriented Programming
Don't put Parent Class in the Child Class , always pass the data to the child class from the Parent Class. e.g. App is parent Class then App should not be in the Child Class . Because it is the method of abstraction.
Put the Code related to the Class only in Class else put in Project (App) Class of the Project.
To Pass the Parent Class use the context .e.g. for passing config variable to the child class.
Each Class is separate entity and should be complete,not dependent on any class and should not give error if something changed in other class.

Becoming Team Leader

2010-11-15T03:20:00.000-08:00

I'm expected to mentor other developers, work on requirements
make design decisions for other developers
evaluate bug reports from users, assign them to developers,
As an individually-contributing developer, my job was to turn my own time in to software that the business could sell for a profit.

As a team lead, my job is to see that the team effectively turns their time in to software that the business could sell for a profit.
Developer has two works only coding and meeting
Team Leader have to do

Meeting with more persons
Delegation - distribution of work
Documentation
Communication to client and others
Mentoring the team .

code review process

2010-10-26T22:33:00.000-07:00

Code review process:

Design: we provided a high level over view of how to solve a problem. No code at this stage. Talk with fellow developer who is available and development manager. Benefits of early design review is getting input that a single developer might have missed. Re-design etc if required.
Code it.
Submit code/link to code changes to another developer for peer review via email/electronically. Best bet is to submit it to a developer who was not involved with design review. Note that the reviewer should review the code without input from the original developer. This is important. We approach it this way for several reasons. If the code can be understood by someone who has not written it then it is safe to say it is maintanable should the original developer be no longer around to ask (left the company or whatever) or even if they are. If the code reviewer cant understand the code then its given back to the developer and he/she makes it more understandable either by greater documentation or refactoring the code. It could be as simple as adding more information to the bug description that the code change is realted to. This in it self saves so much time in the future. The ability to pick up someone elses code and understand it quickly is very advantageous.
Developer and code reviewer get together and discuss code/improvements.
Developer makes changes if required.

Types of Code Review Activity:

1. Desk Review

2. Peer Review

3. Panel Review

4. Client Review

Desk Review /Informal Review:

1. As a Senior Developer/ team lead / Project lead can sit with developer in his machine and check the complex component implementation.

2. Review the naming convention, number of lines per method or class and for loop, if else ladder, Map or List or array usage and review the developer business logic understanding and implementation.

3. Provide the on the fly review comments to the developer to focus on the key implementation skeleton.

Peer Review:

1. As part of any logical component implementation completion, the developer can call for the Peer Review.

2. Peer will be identified with in his track/team and the code artifacts needs to be submitted to the peer by the developer

3. Identified peer will review the code artifacts against the coding checklist as well with the help of coding guidelines

4. Peer will provide the review comments to the appropriate developer and Keep the Team Lead/Project lead in the communication loop.

Panel Review:

1. Panel will be identified with in the project

2. Panel consist of Architect, SME, Lead, Senior Developers (max 5- 8 people)

3. End of Specific Service or Functionality formal component implementation completion, the code or deliverable will be submitted to the Panel by the respective track or team lead.

4. Panel member will do the offline review on the code/artifacts thoroughly

5. Panel needs to check the Implementation strategy, design pattern, reusability, QoS and the functional logic implementation.

6. Panel will gather in the Meeting room and the team lead /code owner will present the code to panel and walkthrough the artifacts.

7. Panel will raise the concern or identified gap in the meeting and the panel member will discuss the gaps.

8. Finally the panel will recommend the refactoring or approve the code for baseline.

9. All the review comments will be prioritized under one of the following criteria such as Development change/refactoring, bug, design issue, requirement missing, Change Request etc

Client Review:

1. After the panel review ,the code will be given to the Client Technical panel (if your project structure has this?) and receive their inputs for further beautification in your client deliverables.

Finally your project manager will take the summary of the code review metrics from the tool and use that for code quality metrics/ SLA Base line.

ulip vs mutual fund......

2010-06-30T01:40:00.000-07:00

Mutual Fund are pure investments. ULIP are combination of Insurance and Investment.

First question that we need to answer while buying ULIP is - Do I need to buy insurance?

1) Does the person seeking insurance have any financial liabilities?
2) If something happens to the person, Is there someone who can be in a financial crisis?

1) Insurance
ULIPs provide you with insurance cover.
MFs don’t provide you with insurance cover.

A point in favor of ULIPs. But let me tell you that you don’t get this insurance cover for free. Mortality charges (i.e. the price you pay for the insurance cover) get deducted from your investment.

2) Entry Load
ULIPs generally come with a huge entry load. For different schemes, this can vary between 5 to 40% of the first years premium.
MFs do not have any entry load.

Tax saving MF ( Popularly called as Equity Linked Saving Scheme or ELSS) come with a lock-in period of 3 years. Other MFs don’t have a lock-in period. Again MFs have advantage over ULIPs. ULIPs do allow you to take money out prematurely but they also put penalties on you for doing that.

2010-06-25T05:38:00.000-07:00

1. You own a part of the business

The good news is, since you own part of the company, you are entitled to a share in its profits.

The bad news is that you are also expected to bear the losses, if any.

2. In the short-run, the price of the share can wildly fluctuate

Let's say the company fixes the price of each share at Rs 10. This is called the face value of the share.

When the share is traded in the stock market, this value may go up or down depending on supply of and demand for the stock.

If everyone wants to buy the shares, the price will go up. If nobody wants to buy the shares, and many want to sell them, the price will fall.

The value of a share in the market at any point of time is called the 'price of the share' or the 'market value of a stock'.

A share with a face value of Rs 10 may be quoted at Rs 55 (higher than the face value) or even Rs 9 (lower than the face value).

So you might have paid Rs 15 for a share which is now quoting at Rs 12. Don't panic and sell. If it is a good company, the share price will eventually rise.

The prices will get influenced by the market sentiment and the general direction of the market. As a result, you may see short-term slumps.

4. Decide how much you want to invest

5. Don't rely solely on 'good advice'

It doesn't matter who is buying the stock or who is recommending it. Steer clear of such ways of making a fast buck. These tips will land you in a soup.

When you hear of a 'hot tip', dig further.

6.. There are many things to remember when you buy shares. stop loss, short sell, Intraday, Delivery, Cash trade e.t.c.

}

FOR MAKING THE GROUPING STORE IN EXTJS I HAVE USED THE FOLLOWING CODE

var SimpleDataStore = new Ext.data.GroupingStore({
proxy: new Ext.data.HttpProxy({
url: 'tasklist.php',
method: 'POST'
}),
reader: new Ext.data.JsonReader({

},
[
//this is field in database
{name: 'id', type: 'numeric'},
{name: 'customer', type: 'string'},
{name: 'project', type: 'string'},
{name: 'employee', type: 'string'},
{name: 'task', type: 'string'},
{name: 'duedate', type: 'date'},
{name: 'handsonhours', type: 'numeric'},
{name: 'completiondate', type: 'date'},
{name: 'comment', type: 'string'},
{name: 'dayleft', type: 'string'},
{name: 'buffhours', type: 'string'}

]),
sortInfo:{field: 'customer', direction: "ASC"},
groupField:'customer' // this script used to classify by country
});

FOR GIVING FILTER TO THE GRID USED THE FOLLOWING CODE....

var filters = new Ext.ux.grid.GridFilters({
local:true,
filters:[
{type: 'numeric', dataIndex: 'id',store: SimpleDataStore},
{type: 'string', dataIndex: 'customer',store: SimpleDataStore},
{type: 'string', dataIndex: 'project'},
{type: 'string', dataIndex: 'employee'},
{ type: 'string',dataIndex: 'task'},
{ type: 'date',dataIndex: 'duedate'},
{ type: 'numeric',dataIndex: 'handsonhours'},
{dataIndex: 'completiondate', type: 'date'},
{dataIndex: 'comment', type: 'string'},
{dataIndex: 'dayleft', type: 'numeric'},
{dataIndex: 'buffhours', type: 'numeric'}
]});

FOR OPENING THE FORM ON CLICK OF THE ADD BUTTON.....

USE THIS FUNCTION.....

function addTab(){

feed aggreegator in ruby on rails

2010-05-01T22:14:00.000-07:00

to fetch the feed to the db
def cfeed
if params[:recache] and params[:secret]=="at123"
cache_feeds
expire_fragment(:controller => 'public', :action => 'index') # next load of index will re-fragment cache
render :text => "Done recaching feeds"
end
end

uses the feed tool gem

# This will replace cached feeds in the DB that have the same URI. Be careful not to tie up the DB connection.
def cache_feeds
puts "Caching feeds... (can be slow)"

feeds = Feed.all.map do |uri|

feed = FeedTools::Feed.open( uri.address )
{ :uri => uri.address, :title => feed.title,
:items => feed.items.map { |item|
{:title => item.title, :published => item.published, :link => item.link,:description=>item.description,:author=>item.author} } }

end
feeds.each { |feed|
new = CachedFeed.find_or_initialize_by_uri( feed[:uri] )
new.parsed_feed = feed
puts feed
new.save!
}
end

and for showing the feeds from db to page..

@f=Feed.find(:all)
@aggregate = read_cache unless read_fragment({})

def read_cache
@fr=@f
@fr.map { |uri|
begin
feed = CachedFeed.find_by_uri( uri.address ).parsed_feed
feed[:items].map { |item| {:feed_title =>feed[:title], :feed_item => item} }
rescue
[] # because there might not be anything cached for some feed(s)
end

} .flatten .sort_by { |item| item[:feed_item][:published] } .reverse
end

and for the view part use the following code

<% cache do %>
<%
lastday = -1
@aggregate.each do |item| %>

<%
mydate = item[:feed_item][:published].getlocal
if mydate.yday != lastday
%>

<%= mydate.strftime("%b %d,%Y" ) %>

<%
lastday = mydate.yday
end
%>

"><%= item[:feed_item][:title] %>

<%=item[:feed_item][:description]%>

<% end %>
<% end %>

this will make your feed agreegator hopefully better..

Password Encryption through javascript

2010-04-30T01:57:00.000-07:00

hii

in my site in admin panel was wanted to do the password encryption of ruby on rails so i got some resources for it and implemented like this,

first my form of login is like this..

  <%= javascript_include_tag('rsa/jsbn', 'rsa/prng4', 'rsa/rng', 'rsa/rsa', 'rsa/base64', :cache => true) %>

 <% form_tag session_path, :id => 'login' do -%>
 
   Please Login
   Login
   <%= text_field_tag :username, params[:username] %>

   Password
   <%= password_field_tag :upassword, params[:upassword] %>

   <%= hidden_field_tag :password, '' %>
 

 <%= submit_tag 'Log in' %>
 <% end -%>
  <%= hidden_field_tag :public_modulus, @public_modulus %>
 <%= hidden_field_tag :public_exponent, @public_exponent %>
Two things to note here. First, we are including the four necessary JavaScript libraries on this page only. Second, we use a hidden field to store/commit the password – this field is populate via JavaScript.

and in the controoller :::::::::
 def new
   key = OpenSSL::PKey::RSA.new(1024)
   @public_modulus  = key.public_key.n.to_s(16)
   @public_exponent = key.public_key.e.to_s(16)
   session[:key] = key.to_pem
 end
def create
   key = OpenSSL::PKey::RSA.new(session[:key])
   password = key.private_decrypt(Base64.decode64(params[:password]))
   user = User.authenticate(params[:username], password)
   if user
     reset_session  # reset session after login
     session[:user_id] = user.id
     flash[:notice] = "Welcome back, #{user.username}"
     redirect_to admin_url
   else
     flash[:error] = 'Invalid username/password entered'
     new and render :action => 'new'
   end
 end

Formating date Time in Rails

2010-04-10T23:23:00.001-07:00

Formating date Time in Rails

You can format Date field by using strftime function

example :

Time.now()
=> Wed Dec 12 15:48:59 +0530 2007

Time.now().strftime(“%d/%m/%y %H:%M”)
=> “12/12/07 15:50″

Here’s the (shortened) table for strftime.

%a weekday name.
%A weekday name (full).
%b month name.
%B month name (full).
%c date and time (locale)
%d day of month [01,31].
%H hour [00,23].
%I hour [01,12].
%j day of year [001,366].
%m month [01,12].
%M minute [00,59].
%p AM or PM
%S Second [00,61]
%U week of year (Sunday)[00,53].
w weekday [0(Sunday),6].
W week of year (Monday)[00,53].
x date (locale).
%X time (locale).
%y year [00,99].
%Y year [2000].
%Z timezone name.

How does respond_to work in the Rails controllers?

2010-04-10T22:26:00.000-07:00

WTF is going on?!?! (aka the rails respond_to block)

respond_to do |format|
 format.html
 format.xml  { render :xml => @mah_blogz }
end

The key thing to understand is that respond_to is a method attached to your controllers superclass: ActionController, and we are passing in as an argument something called a block:

respond_to (BLOCK STARTS HERE) do |format|
 format.html
 format.xml  { render :xml => @mah_blogz }
end (BLOCK ENDS HERE)

WTF is a block?

It’s like the innards of a function. Read this great post by Eli Bendersky.

Digging into Rails source: respond_to (edited for clarity)

def respond_to(&block)
 responder = Responder.new(self)
 block.call(responder)
 responder.respond
end

What’s the “&” prefixing the block argument?

We are passing respond_to a ruby block. That block is converted to a Proc due to the “&” prefix to the block argument. The functionality of this prefixed “&” is a Ruby feature. Procs are callable, anonymous functions.

So what’s with the |format| stuff back in the controller?

|format| defines that the block takes one argument (referred to inside the block as ‘format’).

This means that inside the respond_to method, we end up with a Proc that takes one argument. This argument has the .xml and .html methods called on it. What do we pass into the Proc as an argument when we call it from inside respond_to? We pass in an instance of the Responder class.

So we end up calling .html and .xml on an instance of the responder class as it is passed into the block (that’s been converted to a Proc) inside the respond_to method… Phew.

So here we are

I’ll leave you to dig further, but basically from here the Responder instance handles .html and .xml via method_missing, depending on mime types your rails app can process. This allows you to configure other mime types from your rails app by registering them in your initialisers.
