i committed site path configuration file into git repository in my drupal module. After some commit only i created the gitignore file and add path configuration file into gitignore. I have to remove that configuration file from my previous commit also. To do that just to :
$ git filter-branch --tree-filter 'rm -f my_file' HEAD

If i run PHP code with some error, it says server not found or displaying blank page, it is not displaying the error.
Solution:
To display error output we need to change display_errors = Off to display_errors = On in php.ini file.
Once any changes made in php.ini file must restart the Apache server. Then only the changes will update.

i am working with “inherited_resources” gem today. First read https://github.com/josevalim/inherited_resources.

Hi,
While we creating some forms, also need to create some additional forms. In rails can easily create those type of form using gem “nested_form”. It can manage multiple nested models in a single form. To know more https://github.com/ryanb/nested_form.
can see how it works
i have two model name Project,task. Project has many task. i want to create multiple task when create a project.
include gem in Gemfile
gem "nested_form", :git => 'https://github.com/ryanb/nested_form.git'
then run command in project directory
$ bundle install
This gem add new nested model by using JavaScript. it automatically create JavaScript file.To create JavaScript run this command
$ rails g nested_form:install
now one file created in public/javascripts/nested_form.js
copy the nested_form.js to app/assets/javascripts/
if your server is running restart to load new installation.
set controller and model like
projects_controller.rb
class ProjectsController < ApplicationController def index @projects=Project.all end def new @project=Project.new @project.tasks.build end def create @project=Project.new(params[:project]) @project.save flash[:notice] = "Successfully Created project." redirect_to projects_path end def edit @project=Project.find(params[:id]) end def update @project=Project.find(params[:id]) @project.update_attributes(params[:project]) flash[:notice] = "Record Successfully updated" redirect_to projects_path end def destroy @project=Project.find(params[:id]) @project.destroy redirect_to projects_path end end
in project.rb
class Project < ActiveRecord::Base has_many :tasks, :dependent => :destroy attr_accessible :tasks_attributes,:name, :description accepts_nested_attributes_for :tasks, :allow_destroy => true validates :name, :presence => true end
in task.rb
class Task < ActiveRecord::Base belongs_to :project end
in my views/projects/_form.html.erb
<%= nested_form_for @project do |f| %> <%= f.label :name %> <%= f.text_field(:name) %><br /> <%= f.label :description %> <%= f.text_field(:description) %><br /> <h3> Tasks</h3> <%= f.fields_for :tasks do |task| %> <%= task.label :name %><br /> <%= task.text_field :name %><br /> <%= task.link_to_remove "Remove this task" %> <% end %> <p><%= f.link_to_add "Add a task", :tasks %></p> <%= f.submit %> <% end %>
f.fields_for :tasks render the partial file “task_fields” create partial file name as _task_fields.html.erb in views/projects/
and include the nested fields.
while click “link_to_add’, “link_to_remove” it calls the addField removeField in nested_forms.js file.
Nested form fields are added via javascript.
thanks..
Hi,
i am learning css, i created simple Animated menu bar, let see
first create the menu link like
<html> <head> <title>Testing menu</title> <link rel="stylesheet" href="reset.css"> <link rel="stylesheet" href="menu.css"> </head> <body> <div id='container'> <div id='navbar'> <ul> <li><a id='image1' href='#'>Image1</a></li> <li><a id='image2' href='#'>Image2</a></li> <li><a id='image3' href='#'>Image3</a></li> <li><a id='image4' href='#'>Image4</a></li> <li><a id='image5' href='#'>Image5</a></li> <li><a id='image6' href='#'>Image6</a></li> <li><a id='image7' href='#'>Image7</a></li> <li><a id='image8' href='#'>Image8</a></li> </ul> </div> </div> </body> </html>
i included here reset.css. This css used to reset all the default properties for the element. Then we write the our own css to over write the existing css setting.
in my reset.css
html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, font, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td {

outline: 0;
font-weight: inherit;
font-style: inherit;
font-size: 100%;
font-family: inherit;
vertical-align: baseline;
}
/* remember to define focus styles! */
:focus {
outline: 0;
}
body {
line-height: 1;
color: black;
background: white;
}
ol, ul {
list-style: none;
}
/* tables still need 'cellspacing="0"' in the markup */
table {
border-collapse: separate;
border-spacing: 0;
}
caption, th, td {
text-align: left;
font-weight: normal;
}
blockquote:before, blockquote:after,
q:before, q:after {
content: "";
}
blockquote, q {
quotes: "" "";
}
In my menu.css file
#container{
width:500px;
margin:auto;

ul{
overflow:hidden;
line-height: 83px;

float:left;

Hi,
i just go through the hook_block and create a custom block in drupal 6. The custom module file as follows,
The custom.info file as
; $Id: shan.info,v 1.0 2011/10/04 19:32:28 Exp $ name = custom description = this is my custom test module. package = custom modules core = 6.x
The custom.module file as
/**
* Implementation of hook_block()
*/
function custom_block($op='list', $delta=0, $edit=array()) {
switch ($op) {
// Declare the list of blocks to create
case 'list':
$blocks = array();
$blocks['custom_block1'] = array(
'info' => t('custom_block1 information'),
);
$blocks['custom_block2'] = array(
'info' => t('custom_block2 information'),
);
return $blocks;
// in this case assign the content for the listed block
case 'view':
switch ($delta) {
case 'custom_block1':
// assign the value for the custom blocak one.
$block = array(
'subject' => t('Title of custom block1'),
'content' => "content of custom_block one" ,
);
break;
case 'custom_block2':
// assign the value for the custom blocak two.
$block = array(
'subject' => t('Title of custom block2'),
'content' => "content of custom_block two" ,
);
break;
}
// all the value of the block passed in this variable $block
return $block;
}
}
Make the both files in custom folder as past the module in /sites/all/modules/custom. Install the custom module, now the two custom block created in block like
Now assign the blocks to region required region. i assigned the blocks to right slider bar it shows block content like

hi,
i created a custom region in drupal6. i used the Zen based Airyblue Theme.
Default available region in this theme included in themename.info file. If is not available in this file, you first include the available region.
regions[sidebar_first] = first sidebar regions[sidebar_second] = second sidebar regions[navbar] = navigation bar regions[content_top] = content top regions[content_bottom] = content bottom regions[footer] = footer regions[closure_region] = closure
i add the new custom region in themename.info file name as “header-right” like below
regions[sidebar_first] = first sidebar regions[sidebar_second] = second sidebar regions[navbar] = navigation bar regions[content_top] = content top regions[content_bottom] = content bottom regions[footer] = footer regions[closure_region] = closure regions[header_right] = header-right
now the new region display in block. Then where you want the new custom region to appear in your page, included in page.tpl.php. i include the block below the header.
<?php if ($header_right): ?> <div id="header-right"><div id="header-right-inner"> <?php print $header_right; ?> </div></div> <!-- /#header-right-inner, /#header-right --> <?php endif; ?>
Write the css for this
#header-right
{
float: right; /* LTR */
width: 120px;
margin-top: -87px;
margin-left: 0; /* LTR */
padding: 0; /* DO NOT CHANGE. Add padding or margin to #header-right-inner. */
}
#header-right-inner
{
margin: 0 18px 0 0; /* LTR */
padding: 0;
}
Now the new region displayed in the top right corner like,
now assign the block for this region. It will show like
thanks,
