Nested forms validation problem
Hi All,
I''m trying to learn Ruby on Rails and have got an issue with the
validation of a nested form. I think I have got it setup correctly as it
appears to be saving the data as expected, but it is not wrapping the
CSS class (field_with_errors) to the fields, and if data is entered into
the nested fields it disappears on form submit (if there are validation
errors). The validation

2.3 Nested Model Forms; build new without updating existing
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

a <div class="field_with_errors">.
But who create that div? field_text helper do it?

Best way to instanciate an empty address element in many nested fields_for
Hi!
I have 3 models, User, Company and Address.
Basically, a User belongs to a Company and an Address has one Company

In a form I want to display a User, its Company and its company Address,

The problem is when my User has a Company, that does *not* have an Address:
the part containing the Address is not displayed.

I''m following the gem examples. The form_for works but when I add

Are there other examples of how this works anywhere?

nested forms in rails 2.3
Hi,
Is there a simpler way to implement the view-component of nested forms

I''d like to add and remove the owned objects dynamically using AJAX
requests, but using f.fields_for :object do |object_form| doen''t let
me load new objects into the form - or at least I don''t fully
understand how that should

form_tag + fields_for Rails 4
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

Am I wrong or is fields_for not working right in Rails 2.2.2
I may be totally wrong about what the fields_for method is supposed to
do, but for some reason I thought using it scoped an object around an
association.
For example, I have a User class and when you''re creating a new user I
want to use fields_for to add a BillingAddress to the user like so:
<%- fields_for :billing_address do |billing_address_form| -%>
<%= render :partial

form helpers don't seem to work with RJS files...
I’ve been spending a great deal of time chasing this problem. Hopefully
someone sees something obvious I’m doing wrong. Basically anytime I try
to call fields_for from an RJS file or within a partial in the RJS file,
I get the following error. My goal is simply to load a partial into a
div. The fields in this partial require fields_for though. And that’s
where the problem lies.
