Rails4 Association autosave does not work - ruby-on-rails

Question

I am new in Rails.
I have a model association (belongs_to -> has_many), but the application does not save the associated model's id in the foreign key column.
The migration file:
class CreatePartnerAdvertisements < ActiveRecord::Migration
def change
create_table :partner_advertisements do |t|
t.belongs_to :user, index: true
t.belongs_to :county, index: true
t.text :description, null: true
t.string :city, null: true, limit: 100
t.integer :age, null: false, limit: 120
t.integer :height, null: true, limit: 300
t.integer :weight, null: true, limit: 300
t.timestamps null: false
t.timestamps null: false
end
end
end
The model which foreign key's column always 1 after saves
class PartnerAdvertisement < ActiveRecord::Base
belongs_to :user, autosave: true
belongs_to :county, autosave: true
validates_associated :county
end
This is the view
<%= form_for(#partner_advertisement) do |f| %>
<div class="field">
<%= f.label :county %><br />
<%= collection_select :partner_advertisement ,:county_id, County.all, :id, :name, {selected: #partner_advertisement.county_id} %>
</div>
<% end %>
So here, I select a county from the list, but when the parter_advertisement saved, the county_id not modified... same with the user_id...
So it seems in Rails the association saving does not work. Of course I can manually save the foreign key ids if in the controller I get the right parameter from the request.
But for me it will great, if the ActiveRecord could automatically save the foreign keys for partner_advertisement.
The controller:
class PartnerAdvertisementsController < ApplicationController
before_action :authenticate_user!
before_action :set_partner_advertisement, only: [:show, :edit, :update, :destroy]
# GET /partner_advertisements
# GET /partner_advertisements.json
def index
#partner_advertisements = PartnerAdvertisement.where(is_active: true)
end
# GET /partner_advertisements/1
# GET /partner_advertisements/1.json
def show
end
# GET /partner_advertisements/new
def new
#partner_advertisement = PartnerAdvertisement.new
end
# GET /partner_advertisements/1/edit
def edit
end
# POST /partner_advertisements
# POST /partner_advertisements.json
def create
#partner_advertisement = PartnerAdvertisement.new(partner_advertisement_params)
##partner_advertisement.user_id = current_user.id
respond_to do |format|
if #partner_advertisement.save
format.html { redirect_to #partner_advertisement, notice: 'Partner advertisement was successfully created.' }
format.json { render :show, status: :created, location: #partner_advertisement }
else
format.html { render :new }
format.json { render json: #partner_advertisement.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /partner_advertisements/1
# PATCH/PUT /partner_advertisements/1.json
def update
respond_to do |format|
if #partner_advertisement.update(partner_advertisement_params)
format.html { redirect_to #partner_advertisement, notice: 'Partner advertisement was successfully updated.' }
format.json { render :show, status: :ok, location: #partner_advertisement }
else
format.html { render :edit }
format.json { render json: #partner_advertisement.errors, status: :unprocessable_entity }
end
end
end
# DELETE /partner_advertisements/1
# DELETE /partner_advertisements/1.json
def destroy
#partner_advertisement.destroy
respond_to do |format|
format.html { redirect_to partner_advertisements_url, notice: 'Partner advertisement was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_partner_advertisement
#partner_advertisement = PartnerAdvertisement.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def partner_advertisement_params
#params[:partner_advertisement]
params.require(:partner_advertisement).permit(:age, :height, :weight, :city, :county, :description, :style, :club, :level, :goal, :weekly, :occasionally, :years, :is_active)
end
end
The update request's log without any errors:

So you can see the county_id is 9 in the request, but in the database always 1 after save... :(

Answer 1

You need to allow the county_id in your partner_advertisement_params.
Just add it like:
def partner_advertisement_params
#params[:partner_advertisement]
params.require(:partner_advertisement).permit(:age, :height, :weight, :city, :county, :description, :style, :club, :level, :goal, :weekly, :occasionally, :years, :is_active, :county_id)
end
