thanks everybody.
shold I put my answer into the subject line ?
What do you want to do exactly ? multiple model forms on one page (form_tag); multiple forms and submitting both or mixing model forms (form_for, fields_for) with non-model fields ?
Please explain your use-case.
Sorry for my bad forms. I want to multiple some the same model form and one submit in one page. There will be a def in the controller to create some objects to recieve all the model forms, but now, for example, @choices = Array.new(3){ Choice.new(params[:choice]) } #create objcets with the recieved forms params [:choice] means it can only comes one model form, what should I do to make all the forms come into the def??? Thanks for your time.
