Where did this value in a form come from?
Newb here.
I have a form and a value that is being displayed ... and I have no idea
where the value came from.
I have done a
<%= debugger; '''' %>
in the form and, indeed, the debugger stops at the statement.
I have tried to trace through the code to see where the value came from
... and I gave up.
So ... what in Rails initializes the fields of a form?

Can only render or redirect once per action - why?
I ran into this error message a quite a few times since my app requires
branching to different pages from the same action... say using a switch
statement. Ofcourse I found that you can use multiple redirects or renders
if you do
render :action => ''new'' and return false
I hate to code something I don''t understand fully. Any explanation of this
will be greatly

Could someone please demonstrate the code to send both json (or xml) AND
javascript (to be executed) in a single Ajax request?
Is this even possible?

calling render with query string
Hi all,
In one of my create action in the controller, I am catching a error
and trying to show errors on the same page. It was all good when I
called render action => ''new''. However, I also wanted to append a
query string for consistence purposes. How do I do that with render?
For now, I can only call redirect_to and put the error in the flash
variable which

rendering images dynamically
Hi,
I have a rails application where I respond to a request by fetching
image urls from various web api calls and need to display them as they
come available. I am able to display all the images once I get them
all, but that causes an unacceptable delay for my user.
One approach I am trying is, from my controller, set an @image
variable, and then pass in a block to the model that retrieves the

Can I omit respond_with.
If I don''t want xml results but only html can I omit respond_with in
some actions?
For example index from:
respond_with(@sectors = Sector.all)
becomes only
@sectors = Sector.all
isn''t it?

Does Devise make use of a "status" method? Weird bug.
So I''ve inherited a legacy application and I''m trying to work around the
edges as I put an admin tool interface on top of the existing code base.
I install Devise for user authentication, since I''ve used it in the
past. I change none of the default code. And yet, on successful sign
in, I get an error:
Render and/or redirect were called multiple times in this action.

Close Modalpopup with RJS
hi guys:
I''m scratching my head on this one: I have a twitter app where I''m
trying to open a modalpopup with a twitter sign in, get them to sign in,
then close the popup and refresh the main window. My code however
refreshes the main window with the popup window result, which I thought
was really strange:

Trying to look up comment through an ID, but failing
I am trying to allow users to reply through comments by allowing users
to click a reply link next to the parent comment. It will send in a
parameter to the ''new'' comment view, like so:

The form will use the :in_reply_to parameter in order to save that id as
