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

Change this line

= f.fields_for :relationship do |builder|

to this:

= f.fields_for :relationships do |builder|

Your issue has_many relationships - plural. That will give you the correct relationships_attributes parameters.
