similar to: return custom http responses from a controller?

I tried to write a function like this f1 <- function(){ if (condition 1) return if (condition 2) return ... if (condition 3) return do more work } Where I am using return to exit the function prematurely when I detect conditions that warrant it. Return doesn't seem to work this way. How should I do this? Chris Marshall

I want a method in app/controllers/application.rb that can prepend/append text to whatever template gets rendered. Of course I can''t call render twice w/o getting a double render error, so is this possible? I want to redirect after a delay using a meta refresh. Here''s what I''ve got: app/controllers/application_controller.rb: def redirect_after_delay (url, delay)

Hi All, I took this idea Christian Hellsten and Jarkko Laine''s "Beginning Ruby on Rails E-Commerce". Here is the situation. I will be using the "options_from_collection_for_select" and "collection_select" form helper methods in my view to render drop-down selection lists for City and State that have corresponding city_id and state_id foreign key references

I''m brand new to rails and am trying to build a simple ajax email collection form. It''s just a coming soon sort of thing where the user can enter his email address in the field, hit submit, and the ajax form dumps the email into the database and says "success" unless the email is blank or not unique in which case it says "failure." The trouble is, no

Noobie question here. :) I have a form with check boxes on them. I simply want the user to check the appropriate boxes, click the action (Add Visits). It''s my understanding, that these check box values go into a hash (add_visit_for_this_Pt), but I can''t seem to get this hash back to my controller for processing. Below is my form. Basically, all the controller is

Hi list, I have been trying to get the new file extension for Ogg FLAC (.oga) to work with Amarok. But it does not look to be possible due to limitations in the xine and gstreamer engines. Maybe the move to .oga was prematurely? I have done some testing with other players?including Banshee, Quod Libet, and others?but have not had any success with playing the .oga files. Only player I have

i think self.method just like class method,so if i want to define it as a private method,i should use private_class_method :my_method but i found follow code in < <Agile Web Development with Rails>> private def self.hash_password(password) Digest::SHA1.hexdigest(password) end just a mistake or there have some thing which i cannot get?

Probably asked and answered, but... Why are controller private methods inaccessible inside the block passed to render :update ? This does not work: class MyController < ApplicationController def some_action render :update do |page| page.replace_html ''an_element'', some_private_method end end private def some_private_method return

Good morning, I''ve been working on my first Rails app. I''m replacing an old Perl script that scrapes a bunch of data from an Oracle database, generates a bunch of charts then builds a static webpage with the charts. I''ve re-built it in Rails, with about 25% of the code it took to do in Perl and the users can now get dynamic charts instead of day old charts (or

I''m writing a wizard-like module in my application where, in a series of steps, the user builds upon an ActiveRecord object, and in the end, saves the AR object into the database. The ActiveRecord object is fairly complex, with a has_many association that could potentially get large, so I don''t want to store it directly in the session. In fact, having done so already caused a

I am attempting to establish SIP peering between Asterisk and an AltiGen soft PBX. This is my first experience with SIP peering. I can successfully make both inbound and outbound calls to/from a softphone on the AltiGen system (network access is provided by a PRI on the Asterisk system), but they are disconnected unexpectedly. The attachment is a redirect of the Asterisk CLI during a call that

Hi I have a model that uses several validation helpers, for example validates_presence_of. Now I want to add a custom validate method for a very complex validation. I override validate in the model and it works by itself but when I do this the helper validations stop working. I guess the helper methods rely on the ActiveRecord::Base#validate original method in some way. Has anyone any suggestions

Hi, I''m using Mechanize, and I''ve developed a lot of code around it. I''d like to be able to check the Etag header during a get to see if the page has changed, as well as some other http header information. Can I do that without hacking Mechanize myself? Does anyone have any examples of how to do this? William
