search for: link_to_if

For the life of me I can''t get it to work. Here is an example of my syntax. I''m trying to make comment.name a link to comment.web_site only if there is a comment.web_site. Can someone please help? <%= link_to_if(comment.web_site.length > 0, comment.name, comment.web_site {"class" => "comment_by"}) %> -- Posted via http://www.ruby-forum.com/.

What I wish to do is to have a construct like this in a view: <%= link_to_if <some test>, "New Model View", new_model_path -%> <some test> has to return true if new_model_path is defined and false otherwise. What is the proper idiom to do this in rails 2? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~-...

People, I am using: before_filter :login_required in my Controllers and this works fine. For some tables I am happy to use the output of eg: ruby script/generate scaffold Author but is there some way that I can disable Create, Edit, Destroy for some user logins in the corresponding view?

I have a navigation menu that contains a link per controller in my application. This menu is the same for all controllers, but I want this behaviour: <a>Users</a> <span>Statistics</span> and <span>Users</span> <a>Statistics</a> depending on the page you''re currently on. I''ve put a <render :partial =>

...load, because it doesn''t exist, I get an error. For example, in my controller I have thus: def list @systems = System.find(:all, :order => ''name'', :include => :review) end :review belongs to a :system, which has_one :review In my view I do this: <%= link_to_if !system.review.blank?, system.name, :action => ''edit'', :id => system.review %> This doesn''t work, because it queries the database each time (I''m looping through a collection of 200 items). So my question is, how can I get the link_to_if to check...

Hi all, I''m trying to overload the link_to function, (to disable link_to if the user has no access right) this is my code, it work the first time I run the application, the second time I refresh the page I always get "stack level too deep error" module UsersHelper include ActionView::Helpers::UrlHelper alias_method :link_to_original, :link_to def permission? true

I''m currently using the ACL (Access Control Lists) system in my app. The access control is working great, but I''d like to use the permissions/roles setup in the database to hide links to areas a user may not have access for automatically. I''m guessing that you could setup a helper function to use instead of link_to and have it check the permissions, but

I attached a rails helper implementation of the fb_table described here: http://wiki.developers.facebook.com/index.php/Facebook_Styles I included testing and comments. I hope you find it useful. Curiously, it''s really a small extension of FBML. Richard -------------- next part -------------- Index: test/rails_integration_test.rb
