I'm doing a data entry form for a survey-ish application.
Relevant models are
EvalSheet has_many :eval_responses
EvalResponses belongs_to :eval_sheet
A sheet just serves to let us enter (and reconstruct)
the response data per real-life survey sheet.
I'd like to gather all the responses for one sheet, then
in one go create the parent and all necessary children.
I've tried a few things with form_for, pointing it at
both types of object. EvalSheet seems like the "right" one,
but I can't figure out how to tell it to create the right kind
of input tag names.
The idea for the handling action is something like:
------------------------
sheet = EvalSheet.new
for response in params[:eval_sheet][:eval_responses] do
r = EvalResponse.new(response)
sheet.eval_responses << r
end
sheet.save
------------------------
The raw form tag names I need in order to create what I think
is the the right params hash are like this:
<input type="text" name="eval_sheet[eval_responses][][response]" />
That inner "[]" seems to be what I need to get an array
into the right place in the params hash.
Any hints on how I would use form_for and text_field to
generate that input element though?
Thanks in advance...
