Complex Forms (From Railscasts.com)
Hi,
I have been watching the last three episodes on railscasts.com in
which he goes through dealing with multiple models in one for using
fields_for, and virtual attributes. (http://railscasts.com/episodes/
73). Here is an example of the way they suggest to go about it:
# projects_controller.rb
def new
@project = Project.new
3.times { @project.tasks.build }
end

Noob Question: REgarding Forms ( Take 2 )
I''m hoping there''s an easy way to do this. I''m trying to read options
from a database, and insert them into form tags. So for example,
In the Database Table: options
size: 300
type: text_field

and I want to create a text_field form tag, with all the appropriate
options, is there an easy way to do this, other than having the code

CRUD pattern for has_many relationships (forms containing collections)?
Hello folks!
Beare with me for a second, while I explain my problem.
Assuming we have the trivial model of
class Author
has_many :books
end
class Book
end
How do people go about creating the authors/edit and authors/new
views if you want to be able to add and remove arbitrary amount of
Books at Author creation and edit time? What I mean by this is that I

A quick question on forms
I want to change parts of this form in order to use default values (with a
disabled input). The problem is if I change it from text_field to
text_field_tag that part of the form stops functioning. It seems like a
silly question, but its been driving me crazy. Any help would help.

Single form w/ relationships: how do I integrate it?
OK - I know this has been asked before, but I cannot find it in the
archives. Forgive me if I''m creating more noise than I should.
I want to know the easiest way to deal with this scenario:

On the form where you write an article, there needs to be a free-form
field to entire the category.

RJS and remote forms
I''ve run into what I think is a browser bug related to using
remote_forms pushed in an RJS update.
In my controller, I have an action that creates a new model and returns
a form for one of its children:
def create_party
party = Party.create
render :update do |page|
page.insert_html :top, ''party-list'', :partial => ''party_header'',

Overwrite form helper methods and call old ones in new ones?
Hi all
All my forms should look the same, so I think always putting the right
div etc. tags around them is a violation of the DRY principle.
Until now my forms look like that:
<div class="text_field">
<label for="news_item_subject">Subject:</label> <%= text_field
"news_item", "subject" %>
</div>
Now I want the default

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

managing belongs_to fields in a form
Hi all,
I cannot find a clean way to create/edit an object that ''belongs_to''
another one, just by using form fields.
I always need to explicitely unassemble it, store the master id in a
hidden field, and then refetch the master from its id, and put it back
in the object.
To summarize:
I want to create a new member, for a given project
