I''m trying to build something similar to a Facebook messaging app, in which the view displays all the messages for a particular thread, with a form box for replying at the bottom of the thread. The problem is that using fields_for generates form fields for each existing record, and for one new record. In this case, there is no need to edit existing messages - just a need to add new

Hi There, I''m trying to user fields_for inside a form_tag, but i can''t catch it on my controller. I just take some html code off to makes it easy to read my view... i''m using campuses_path(current_church, @campus) instead form_for @campus, because my route is like resources :campuses, :path => ":church/campuses" <%= form_tag

I''m using the fields_for helper with accepts_nested_attributes_for The System model has_many children.

So I would like to be able to update a record without having to load the edit page. Lets use checking out a book as an example. From the front page of my application I would like to be able to have a form field where I can enter a record id and select one of a couple of check boxes and then hit submit which will update the associated record with the action selected by the check box (check out,

With the help of several heroes here yesterday I beat my way into a working solution to adding comments to one or more models in my application using acts_as_comentable. Great plugin, but my implementation is lame. I need enlightenment. I have users who log in. For several views I want to let them add comments. Enter act_as_commentable which does just this -- it''s polymorphic, so you

Hello, I think this is an easy one for the average Rails developer but I''m a bit stuck. I''m creating a simple voting app: any user can create a survey, with any number of questions, and other users can then vote by creating a ballot for that survey. Here''s the modeling: class Survey < ActiveRecord::Base has_many :questions has_many :eligibilities has_many

Hi, guys. There are four models in the program, A has_many B through C, B has_many A through C, A has_many D, D belongs_to A. I have a form to create A. Inspired by Ryan Bates'' railscasts I was able to create A and D in the same form, and link A to B(created beforehand) through C in the same form as well. Is it possible to create A and B in the same form? Thanks in advance. -- Posted

I just did a large upgrade to to Rails 2.3.4 and I am trying to make use of the more modern view features. I have a Newsletter object. Newsletter has many Sections. I also have: accepts_nested_attributes_for :sections on the Newsletter object.

When submitting billing information in the past I''ve always used attr_accessor for credit card details as they should not be saved in the database. In addition I always end up storing the card expiration date so that the date form helper works correctly. With Active Model it seems logical to create a CreditCard class to hold this data instead. **1st issue.** It seems there still

Hello everyone, I''m just trying to understand some logical reasons behind Rails syntax of "select" and "select_tag". I know I can do this: <%= form.select :card_type, supported_card_types, { :prompt => "Please Select..."} %> which sets a model field in the params hash. If I want to do the same for a non-model field,

OK, so I''m an absolute noob at Ruby on Rails. I''ve read a lot of information I can find about form_for and most of them use form_for to create new items that get saved into the database and can be viewed later to edit, destroy, etc. In this case, the database will fill up with whatever the user wrote and I just want my program to have no information stored. I''ve been

In a form_for context, is there a way to access objects that are related to the primary object with a belongs_to? I think an example will serve best: class User < ActiveRecord::Base belongs_to :person attr_accessor :username end class Person < ActiveRecord::Base has_one :user attr_accessor :first_name end <% form_for :user do |form| %> <%= form.text_field

Am interested in the new PATCH method that will be included in Rails 4, but have a question/concern, and forgive me if I''m misunderstanding it. So, if the request parameter _method is set to "patch", the update is processed as a patch. But, let''s say you have a model called Airplane and Airplane has a collection of FlightCrewMembers which it
