Form_tag parameters in nested hash

Question

I have a form that doesn\'t have a model associated with it, so I\'m using form_tag rather than form_for. As expected, when the user submits the form

Answer 1

You can use fields_for inside a form_tag for a more formal way of expressing a namespace.

fields_for :form_fields do |ff|
  ff.text_field :my_text_field
  ff.select :my_select_tag
end

Alternatively just namespace all your form inputs, as such:

text_field_tag "form_fields[my_text_field]"
select_tag "form_fields[my_select_tag]" ...

etc. Then you will get params[:form_fields] = {:my_text_field => "foo", :my_select_tag => "bar"}, which I think is what you wanted.
