Rails 3 Nested Models unknown attribute Error

Question

• I have a model \"Issue\" and a nested Model \"Relationship\"

• In the issue.rb I have mentioned:

  has_many :relationships, :dependent => :d         
  
  
          

Answer 1

By using accepts_nested_attributes, you have created a setter method relationship_attributes=.

There are a couple of things I noticed that need to change.

You don't need to set

@relationship = @issue.relationships.build

Your form should be the following (you have f.fields_for :relationship)

= form_for @issue do |f|

  # your issue fields here

  = f.fields_for :relationships do |r|

    # your relationship fields here

The beauty here is that you won't have to set any ids or anything.
