ID изменен на NULL при обновлении - Rails 4

Question

У меня есть модель арендодателя и landlord_address. Когда создается новый landlord_address, landlord_id сохраняется в таблице. По какой-то причине, когда я редактирую landlord_address, landlord_id изменяется на NULL.

Модели:

class Landlord < ActiveRecord::Base 
    has_many :landlord_addresses, dependent: :destroy 
    belongs_to :listing_agent, class_name: 'Agent' 
end 

class LandlordAddress < ActiveRecord::Base 
    belongs_to :landlord 
    has_many :landlord_companies, dependent: :destroy 
end

Answer 1

Ваш маршрут вложен, вам не нужно назначать в скрытом поле. Вы можете сделать это в контроллере, передавая параметры.

Форма:

Удалить скрытое поле, мы присваиваем его в контроллере!

<div class="field"> 
     <%= f.hidden_field :landlord_id, :value => params[:landlord_id] %> 
    </div><br> 

Контроллер:

# POST /landlord_addresses 
# POST /landlord_addresses.json 
def create 
    @landlord_address = LandlordAddress.new(landlord_address_params) 

    # add this line here! 
    @landlord_address.landlord_id = params[:landlord_id] 

    respond_to do |format| 
    if @landlord_address.save 
     format.html { redirect_to matrix_landlord_landlord_addresses_path, notice: 'Landlord address was successfully created.' } 
     format.json { render :show, status: :created, location: @landlord_address }

Answer 2

Эта часть

<%= f.hidden_field :landlord_id, :value => params[:landlord_id] %> 

будет ваш вопрос. Когда params[:landlord_id] - nil ваша запись будет обновлена ​​до null.

Вы должны изменить его

<%= f.hidden_field :landlord_id, :value => @landlord_address.landlord_id || @landlord.id %> 

или некоторые вещи еще.
