Use form_for for non-attribute values
===

I have a form_for like so:

    <%= form_for(@post) do |f| %>

I would like to submit a parameter that is not an attribute of the model

    <%= f.text_field :label%>

I have a Label model (labels has_many :posts and posts has_many :labels) and in the create action of the posts_controller I want to create a new Label object based off the label text_field. With the above text_field I get:

    undefined method `label'for #<Object>

How can I go about achieving this?


Thanks in advance!
