Hi, I am a rails and ruby nuby :-) How do you pass data between different controllers and views? I have a page ( a quote) that I am editing url ....quote/edit/6 6 id the current id. I then go to a catalog (url....catalog) to add an item to my quote (I do this via a line_item file that the quote reads) I now want to go back to the quote. I have tried this <%= link_to ''Back to

Hi all, I''ve put new code into my app so that an administrator will have extra privileges (administer users, edit pages). The error is: ''Couldn''t find User without an ID'' So the app is looking for a logged in user when the homepage is accessed. Heres my code: site/index view: <% if is_logged_in? and logged_in_user.has_role?(''Moderator'')

Hi all, I am using rails v.2.3.2 and if I put following line to my ApplicationController: include LoginSystem and I moved my login_system.rb to lib folder: module LoginSystem protected def is_logged_in? @logged_in_user = User.find(session[:user]) if session[:user] end def logged_in_user return @logged_in_user if is_logged_in? end def logged_in_user=(user) if

Hello everyone, I am following the Practical Rails: Social Networking sites book. In chapter 7 photo gallery I am getting a NoMethodError in Pages#show Showing layouts/_menu.rhtml where line #12 raised: undefined method `new_entry_path'' for #<ActionView::Base:0x52fa56c> Extracted source (around line #12): 9: <% if is_logged_in? %> 10:

Hello! I have certain methods in my Application Controller, that I need to access. Namely ApplicationController#logged_in_user The problem is, that when I try to access it, I get: NoMethodError: protected method `logged_in_user'' called for #<AdminController> Any ideas how I can circumvent that? Or are functional tests really not suited for any kind of logins and session work?

I''m trying to create a simple authentication system but am failing miserably. I''m (sort of) following the "Logging In" chapter of the Agile book. Ideally, any access to http://example.com/publish (and any of its subdirectories) should redirect to http:/example.com/publish/login when there is no valid session user_id. Code so far:

Hi,- I am looking for a clean and secure way for an ActiveRecord instance to delete itself. Say I have a User model in my app. Then the destructive action would be /users/user_id/destroy. If this action is not secured by a filter like: (*) before_filter :check_administrator_role, :only => :destroy then any user could potentially log in and start issuing: /users/1/destroy /users/2/destroy .

Can I make my model methods aware of the context (preferably instance variables) where they are run, without having to pass them arguments? The app in question should be time zone aware, so something like user.events[0].starts_in should check against @logged_in_user.now rather than Time.now. I could send the user as an argument (user.events[0].starts_in(:timezoned => @logged_in_user)),

I have a view with a form and i want to be able to process the button selected in a controller - not sure how to do this. The form does not map directly to a model - all I want to do is be able to pass back the selected button and know which one it is. So, i have a form and several radio buttons - the submit (not shown) takes me to the process_answer action where I want to determine which

Hi, I would like to figure out how to determine what the id of the last element in a table is. Is there an equivalent to the Table.find() method which will tell me the number of elements in a table? also, maybe more importantly, where are the available methods on tables documented? What i am trying to do is to increment the id and work through a table and check whether the id i am currently

Hello! I was wondering, sometimes I raise an exception in my Rails apps, e.g.: raise SecurityError unless @post.user == logged_in_user Now: is there any way to catch that SecurityError exception somewhere and render a custom template? E.g., I want to render ''app/views/content/security_error.rhtml'' Does anyone know how to do this? Thanks a bunch, Rob

Hi, I have some code in which i open a pop up when a user clicks on a link. However, the new popup window comes with the layout of the page on which the user clicked the link.

Can you use sessions in layered dispatching? I used them in direct dispatching without any problems, but switching to layered throws an error (saying session doesn''t exist).

Hello, I am setting up a red hat machine on a windows network and i am wondering if the samba application needs to be installed onto the server or weather I would get away with it being installed on the local machine only. Thanks for your help, seamus.

Hi all, I am using paperclip plugin to upload mp3''s. Before I save the mp3 I would like to convert it to a smaller size. I am using ffmpeg library and in my Track model I am calling: before_save :convert_mp3 def convert_mp3 system("ffmpeg -i #{mp3.to_file.path} -vn -ar 44100 -ac 2 -ab 64 -f mp3 #{mp3.to_file.path}") end But this fails. Am I missing something?

Hi I''ve got a login action that handles authenticating users, setting cookies and, via its view, displaying an HTML snippet containing a form with username and password fields. It''s called from the main application.rhtml layout so I don''t need to have a seperate page (away from the main site) with a login form. My user model is more-or-less the same as in the Agile RoR
