Rails 4 permit nested attributes doesn't create/update

Question

I convert my rails app(-v3.2.13) to rails 4.I use inherited resources gem's overwriting actions(create! and update!).I permit entire hash of the parameters,But It doesn't create/update the nested attributes.I need to permit the entire hash of the parameters.When i tried, i am getting the following error.Help me to solve this.

params

{"foo"=>{"name"=>"1@1", "detail"=>"123", foo1_attributes"=>{"0"=>{"_destroy"=>"", "name"=>"John", "url"=>"johnsmith.blogspot.com",foo2_attributes"=>{"0"=>{"min_time"=>"0", "max_entry"=>"340"}}, "foo3_attributes"=>{"_destroy"=>"", "hours"=>"01", "minutes"=>"00"}, "status"=>"ACTIVE"}}, "foo4_attributes"=>{"0"=>{"image"=>"0","id"=>"1097"}}}, "commit"=>"Save", "foo_id"=>"13", "id"=>"1467"}

My controller

def update
 update! do |success, failure|
  success.html { redirect_to foo_path }
 end
end

protected

def resource_params
 params.permit!
end

Foo Model

accepts_nested_attributes_for : foo1,foo2,foo3,foo4
has_many :foo1
has_many :foo2
has_many :foo3
has_many :foo4

Answer 1

I faced a similiar kind of problem. Try doing the following. Assuming you need to update foo1. Use this for your strong parameters.

def foo_params
  params.require(:foo).permit(:foo1_attributes => [:bar1 , :bar2])
end

Do update by.

def update  
  if @foo.update_attributes!(foo_params)      
    redirect_to foo_path
  else
    render foo1_edit_path
  end
end

Answer 2

hi you must use it this way:

params.require( :foo ).permit( :name, :details, foo1_attributes: [ :_destroy, :name, :url, :id ], foo2_attributes: [ :_destroy, :min_time, :max_entry, :id ] )

It may solve your problem.
