rails using has_many and belongs_to -

alright, i'm going try explain best possible:

i have 2 models

employer.rb

class employer < activerecord::base      has_many :listings  end 

listing.rb

class listing < activerecord::base      belongs_to :employer  end 

employers login through employers_controller , listings created through listings_controller

i'm having trouble getting id employer table being inserted employer_id column in each individual created listing. hope makes sense. if has advice, appreciated. have feeling because i'm doing outside of employer_controller, not sure.

thanks!

1) if not dealing nested resource then

when render new action of listing controller, know employer (@employer) want create listing.

so render hidden field employer_id using hidden_field or hidden_field_tag

hidden_field_tag 'employer_id', @employer.id() 

2) if dealing nested resource , route looks /employers/:employer_id/listings/new / (get) && /employers/:employer_id/listings

then in create action

@employer = employer.find(params[:employer_id]) @employer.listing.new(params[:listing]
