Rails 4, mise à jour de ressource polymorphe imbriquée

Question

J'ai configuré une ressource polymorphe en utilisant accept_nested_attributes_for mais pour une raison quelconque, lorsque j'essaie de mettre à jour, au lieu de simplement mettre à jour l'enregistrement en cours, j'en crée un nouveau. Est-ce que quelqu'un peut me dire quel est le problème? Merci.

vendors_controller.rb

class VendorsController < ApplicationController 
    before_action :authenticate_user! #check if user logged in 
    before_action :set_vendor, only: [:show, :edit, :update, :destroy] 

    def index 
    @vendors = current_company.vendors 
    end 

    def new 
    @vendor = current_company.vendors.build 
    @vendor.addresses.build 
    end 

    def create 
    @vendor = current_company.vendors.build(vendor_params) 
    if @vendor.save 
     flash[:notice] = 'New Vendor Added' 
     redirect_to vendors_url 
    else 
     flash[:error] = 'Could not save vendor information. Please try again.' 
     render 'new' 
    end 
    end 

    def show 
    end 

    def edit 
    #@vendor = Vendor.find(params[:id]) 
    #@vendor.addresses.find_or_initialize_by(addressable_id: @vendor.id, addressable_type: 'Vendor') 
    end 

    def update 
    #@vendor = Vendor.find(params[:id]) 
    if @vendor.update(vendor_params) 
     flash[:notice] = 'Vendor Updated' 
     redirect_to vendors_path 
    else 
     flash[:error] = 'Could not save vendor information. Please try again.' 
     render 'edit' 
    end 
    end

    @vendor.destroy

vendor.rb

class Vendor < ActiveRecord::Base 
    belongs_to :company 
    has_many :asset 

    has_many :addresses, as: :addressable, dependent: :destroy 
    accepts_nested_attributes_for :addresses, reject_if: RejectDeeplyNested.blank? 
end 

address.rb

class Address < ActiveRecord::Base 
    belongs_to :addressable, polymorphic: true 
end 

Answer 1

vous devez changer vos paramètres autorisés comme celui-ci

params.require(:vendor).permit(:name, :vendorID, :contact, :email, :phone, :image, :remove_image, addresses_attributes: [:street_1, :street_2, :city, :state, :zip, :id]) 

Answer 2

Vous devez ajouter optional: true à votre relation:

class Address < ApplicationRecord 
    belongs_to :addressable, polymorphic: true, optional: true 
end 

oublié de mentionner que optional est disponible uniquement sur les rails > 5
