I''ve got a field in a database that contains a string of ids. I want to be able to remove an item from that list and save the list again. The only way I saw how to do this was to convert it to an array and back to a string again. The variable names are for an example. This code works, but I don''t think that it''s efficient. It''s all in my controller.

Hi All I''m trying to combine the from_for and select helpers Right now I have form_for :service, :url => ...... do |f| select("abc", "xyz_id", @my_arr.collect {|item| [ item, "bla" ] }, {:prompt => "opt1"} ) .... end What I want to do is something like .... f.select("abc", "xyz_id", @my_arr.collect {|item|

Hello, I am working on a project, and on one form we have a select (drop- down) box where the user needs to be able to select from a list of clients. The box is currently being populated with: <%= collection_select(:client, :id, @account.clients, :id, :name) %> The problem is that some of these clients may have already been selected, and we need to remove them from the list. Is this

...yourself "he''s got to call those select helpers on the pp_form object that the fields_for block yields." If I do that, I get (e.g.): undefined method `merge'' for :nom:Symbol. So are there different select helpers for using inside fields_for?

Okay, this is something I run into a lot and don''t really have a great solution. Here is a simple example: class Blog < ActiveRecord::Base has_many :posts validates_presence_of :name end class Post < ActiveRecord::Base belongs_to :blog validates_presence_of :name validates_presence_of :blog_id end Now, if I want to create a blog and post at the same time I

I am relating to the book & subject example mentioned in the tutorial mentioned here: http://www.tutorialspoint.com/ruby-on-rails-2.1/rails-examples.htm There is a file that goes like show_subjects.html.erb and it will list all the books for that particular subject we''ve selected. Suppose if there were no books to show for the subject we can ideally show a corresponding message

Hi. Although an expert developer for IBM systems (iSeries) I am VERY new to RoR and somehow to the PC development world as well and not familiar AT ALL with PC configurations, etc. (in my regular job good ol'' IBM takes care of all that and I just need to code). So forgive me if any of the following sounds stupid, it probably is. Just get a laugh at my expense and try to answer between

I just installed BackgrounDRb the other day. It''s working great but after I deployed to production, I noticed a couple of strange things happening: 1) I have the following code in a lib module and after deploying, IS_PRODUCTION was set to false. I''m not sure why this started occurring and the only major change was the installation of BackgrounDRb and its dependencies. Could

Your partial uses a simple form_for(@product) call. By default that will do a POST to the products/create action, which if it''s successful, does a redirect to products/show/<<id for the new product>> (see the create method in your products_controller.rb file). My advice is to just play around w/rails for a bit & get used to its conventions before you try to bend it to

Hey All, I''m attempting to upgrade my app from rails 2.0.2 to 2.3.3. One bit that''s failing is this call here (in /views/projects/show.html.erb) <%= markdown(@project.description) %> That earns me a: uninitialized constant ActionView::Helpers::TextHelper::Markdown On that line.
