Keith:
If I get what you’re asking… you might do it this way… off the top
of my head, not tested, may need some ‘tweaking’…
In the controller that produces the form:
@categories = Category.find(:all)
each_with_index {|item, index|
In your view:
#normal form fields for special request
@categories.each_with_index do |c,i|
text_field_tag(“request_item[i][count]”,0)
hidden_field_tag(“request_item[i][category]”,#{c.id})
end
In the controller that processes the form:
params[:request_item].each do |ri|
special_request = SpecialRequest.new(params[:special_request])
special_request.special_request_items <<
SpecialRequestItem.new(‘count’ => ri[‘count’], ‘category_id’ =>
ri[‘cateogory’]) unless ri[‘count’].to_i <= 0
end
Essentially, you are creating many ‘sets’ of the same data (special
request items) in your form, identified by a unique key value (the [i]
part of the form field helper calls). This effectively creates an array
of these ‘sets’ of data, which you step through in your controller and
process accordingly.

Ok I am going to try and explain this as best as I can. It seemed to
be a simple problem but is turning out to be alot more difficult then i
imagined.
I have a table of categories and a table of special requests and a
table of special request items. Special requests have many special
request items and special request items each belong to a category and
also has a interget field for count. Simple right?
So here is the problem. I want to display a form that display empty
text fields for each and every category that ask for the count for this
perticular special request item. All of the special request items with
a count of 0 or higher will be added to this newly created special
request.
relativly straightforward…
where i hit a wall is that these text fields have to communicate back
to the controller not only the count but also the category which they
are refering to and I ahvent a clue where to begin. Any insight into
this problem would be very helpful
Thanks in advance.
