Hi, 'm new to Rails. I tried using _path and _url with link_to helper method but it doesnt work for me.
Does anyone know what can be the issue? my code is
<h1>Hello Rails</h1> <%= flash[:notice] %> <%= link_to 'Show Blog', posts_url %>
Post is my controller
The error 'm getting is undefined local variable or method `posts_url' for #<ActionView::Base: 0x102b23d>
Thanks in advance
Hello Ashit,
If you run "rake routes" in your project directory you'll see what routes are available. Also, the singular vs plural question needs to be considered here.
Typically: The model has a singular name - models/path.rb The controller has a plural name - controllers/paths_controller.rb The view has a plural name - views/paths/edit.html.erb
So a url for your controller would typically be: paths_url

"rake routes" really becomes your friend here as you are able to take a look at everything that will work. Trust me, just run it and look over the output to see where you might be going wrong.
Hi Ashit. Another thing that you can do is test out the various URL and path helpers in your app's console. For example:
$ script/console Loading development environment (Rails 2.1.0)
?> app.photos_url => "http://www.example.com/photos"
?> app.photos_path => "/photos"
?> quit
Cheers, Nick
