Assembly parameter issues for accepts_nested_attributes_for

Question

I'm trying to add user_id to a nested attribute that is created by the parent controller, but it doesn't seem to have the desired effect?

Those. I have a model called Place.rb which accepts_nested_attributes_for :reviewsandhas_many :reviews, :as => :reviewable, :dependent => :destroy

The nested attribute works fine, and I create it inside the Places controller so ...

new action

@review = @place.reviews.build(:user_id => current_user.id)

create action

params[:place].merge(:user_id => current_user.id)
params[:place][:reviews_attributes].merge!(:user_id => current_user.id)* bad
@place = Place.new(params[:place])

this is the original, for the place model, to get user_id, now I need user_id for the model of nested reviews. It may seem strange that there are user_ids in places and reviews, but people can add new reviews for the same place ...

maybe like this, but not working:

@place = Place.new(params[:place].merge(:user_id => current_user.id, :reviews_attributes => { :user_id => current_user.id } ))

get error: undefined methodwith_indifferent_access' for 3: Fixnum`

or

@place = Place.new(params[:place].merge(:user_id => current_user.id, :reviews_attributes => { "0" =>  { :user_id => current_user.id }}))

user_id, NULL; - (

, , user_id , - , user_id ...

, :

<%= e.label :content, "Review" %><br />
<%= e.text_area :content, :rows => 20, :class => 'jquery_ckeditor' %><br />
<%= e.hidden_field :user_id, :value => current_user.id %> #want to remove this line
