Work right through a good tutorial such as railstutorial.org, which is
free to use online.

Hi,
I am very new to rails.. I am having hard times to understand the
ActiveRecord associations.. I tried
http://guides.rubyonrails.org/association_basics.html .. But it is not
for beginners. :)
Is there any good tutorials, to understand the concept?
Thanks

Can I suggest that you work right through a good tutorial such as
railstutorial.org (which is free to use online). That will show you
the basics of rails so that you will be able to answer simple
questions yourself.

Hi Frederick,
If I change the path to tasks_path, I get the following error while navigating on to the page which has this form. If I keep task_path, navigation works fine.
undefined local variable or method `tasks_path' for #<#<Class:0xa3de690>:0xb550f644>I don't see any error in development.log when I click on the Add button. the page re-loads as expected because of "task_path" url but data doesn't persist.

I'm learning on creating a website using Ruby on Rails (RoR). I had an HTML template that I created when I worked with JSP 2 years ago, and now I want to reuse it in my RoR website. This is HTML file
<body>
<div id="container">
<ul id="nav">
<li><a href="index.html">Livingroom</a></li>
<li><a href="about.html">Bedroom</a></li>
<li><a href="#">Mattress</a></li>
<li id="selected"><a href="#">Bathroom</a></li>
<li><a href="#">Kitchen</a></li>
<li><a href="#">Office</a></li>
<li><a href="#">Outdoor</a></li>
<li><a href="#">About Us</a></li>
<li><a href="#">My Account</a></li>
<li><a href="#">SearchBar</a></li>
</ul>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js"></script>
<script type="text/javascript" src="js/jquery.Nav.js"></script>
<script type="text/javascript">
$('#nav').spasticNav();
</script>
</body>
</html>
and this is the javascript file jquery.Nav.js
(function($) {
$.fn.spasticNav = function(options) {
options = $.extend({
overlap : 20,
speed : 500,
reset : 1500,
color : '#0b2b61',
easing : 'easeOutExpo'
}, options);
return this.each(function() {
var nav = $(this),
currentPageItem = $('#selected', nav),
blob,
reset;
$('<li id="blob"></li>').css({
width : currentPageItem.outerWidth(),
height : currentPageItem.outerHeight() + options.overlap,
left : currentPageItem.position().left,
top : currentPageItem.position().top - options.overlap / 2,
backgroundColor : options.color
}).appendTo(this);
blob = $('#blob', nav);
$('li:not(#blob)', nav).hover(function() {
// mouse over
clearTimeout(reset);
blob.animate(
{
left : $(this).position().left,
width : $(this).width()
},
{
duration : options.speed,
easing : options.easing,
queue : false
}
);
}, function() {
// mouse out
reset = setTimeout(function() {
blob.animate({
width : currentPageItem.outerWidth(),
left : currentPageItem.position().left
}, options.speed)
}, options.reset);
});
}); // end each
};
})(jQuery);
In the application.html.erb of RoR project, I include the js file like this
<%= javascript_include_tag "jquery.Nav.js" %>
However, my homepage doesn't work even though I put the <script type="text/javascript">$('#nav').spasticNav();</script> inside the body tag of RoR project
<body>
<div class="container">
<%= render 'layouts/header'%>
<%=yield%>
<%= render 'layouts/footer'%>
</div>
<script type="text/javascript">
$('#nav').spasticNav();
</script>
</body>
Is there anyway to embed the $('#nav').spasticNav() into the js file. I tried many ways but it still doesn't work. Thanks a lot.
EDIT: I saw some examples online that they embed the function into js file like this.
jQuery(document).ready(function($){
/*---------------------------------

$('ul.menu').each(function(){

Hi,
I created a simple form using form_for and partials. When I enter a value in text field and click on add button, the data doesn't get uploaded in database table.
view/task.html.erb
<%= render :partial => "job_form" %>
view/_job_form.html.erb
<%= form_for(@job, :url => task_path) do |f| %>
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.submit "Add" %>
<% end %>
/view/home_login_controller.rb
def task
@job = Task.new
@jobs = Task.all
end
db/<migration stamp>_create_tasks.rb
def change
create_table :tasks do |t|
t.string :name
t.timestamps
end
end
db/schema.rb
create_table "tasks", :force => true do |t|
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
t.string "name"
end
app/models/task.rb
class Task < ActiveRecord::Base
# attr_accessible :title, :body
end
I have done db migration and db schema exists for table but "select * from tasks" doesn't return any rows and therefore UI doesn't show any form data. Can someone please help me debug this issue?
Thanks.

I would change the setup task to
dirs = [File.join(shared_path,'ckeditor_assets' )]
run "#{try_sudo} mkdir -p #{dirs.join(' ')} && #{try_sudo} chmod g+w #{dirs.join(' ')}"
end
and leave the rest of your deploy.rb the same.
Then as long as you run that setup task at least once, current/public/ckeditor_assets should point to shared/ckeditor_assets

I started project to create a library of basic functions (or 'helpers' as you wish) .
The start with ds_string. want to contribute: was already made available at rubygem.org
Has two basic functions:
"A".times(3) => "AAA" (like "A" * 3 )
"A".times(3) do |s| "#{s}-" end => "A-A-A-"
"1".to_b => true
"yes".to_b => true

Hi all, I have Rails 4.0.0 app,
After capistrano deploy my ckeditor_assets are being removed. Could not symlink to shared/ckeditor_assets folder.
I have followed this step :
namespace :uploads do
desc <<-EOD
Creates the upload folders unless they exist
and sets the proper upload permissions.
EOD
task :setup, :except => { :no_release => true } do
dirs = uploads_dirs.map { |d| File.join(shared_path, d) }
run "#{try_sudo} mkdir -p #{dirs.join(' ')} && #{try_sudo} chmod g+w #{dirs.join(' ')}"
end
desc <<-EOD
[internal] Creates the symlink to uploads shared folder
for the most recently deployed version.
EOD
task :symlink, :except => { :no_release => true } do
run "rm -rf #{release_path}/public/ckeditor_assets"
run "ln -nfs #{shared_path}/ckeditor_assets #{release_path}/public/ckeditor_assets"
end
desc <<-EOD
[internal] Computes uploads directory paths
and registers them in Capistrano environment.
EOD
task :register_dirs do
set :uploads_dirs, %w(public/ckeditor_assets)
set :shared_children, fetch(:shared_children) + fetch(:uploads_dirs)
end
after "deploy:finalize_update", "uploads:symlink"
on :start, "uploads:register_dirs"
end
I could not figure this out why my public/ckeditor_assets folder is not copied to shared/ckeditor_assets and doesnt symlink also.
Please help me.

In my project i want to make tasks like in taskrabbit.com, that user could create task and another user could respond on it. And the user who created task could choose candidates and change status to "accomplished" my models:
class Post < ActiveRecord::Base belongs_to :user belongs_to :category has_many :responces end class Responce < ActiveRecord::Base belongs_to :user belongs_to :post default_scope -> { order('created_at DESC') } endmy posts controller
class PostsController < ApplicationController load_and_authorize_resource def new @category = Category.find(params[:category_id]) @post = @category.posts.new(category_id:params[:category_id]) end def index @category = Category.find(params[:category_id]) @posts = Post.all end def create @post = current_user.posts.build(post_params) @category = Category.find(params[:category_id]) if @post.save flash[:success] = "Поздравляем Ваше задание опубликованно" redirect_to post_path @post else render 'new' end end def update @post = current_user.posts.build(post_params) @category = Category.find(params[:category_id]) end def show @post = Post.find(params[:id]) #@category = Category.find(params[:category_id]) @feed_items = @post.responces.paginate(page: params[:page]) end def feed Responce.where("post_id = ?", id) end def destroy @post.responces.destroy redirect_to post_path @post end private def post_params params.require(:post).permit(:destroy, :name, :content, :date, :time, :category_id, :price, :adress1, :adress2) end endmy view
<%= link_to 'Choose candidate', feed_item, method: :update, data: { confirm: 'Are you sure?' } %> </li>and my responce controller
class ResponcesController < ApplicationController def new @post = Post.find(params[:post_id]) @responce = @post.responces.new(post_id:params[:post_id]) @responce.user = current_user end def create @post = Post.find(params[:post_id]) @responce = @post.responces.build(responce_params) @responce.user = current_user if @responce.save flash[:success] = "Вы откликнулись на задание" redirect_to post_path @post else render 'new' end end def show end def destroy @responce = Responce.find(params[:id]) @responce.destroy redirect_to posts_path @post end private def responce_params params.require(:responce).permit(:price, :comment, :post_id) end endCan you help me out with that, how I can make it done.
