將屬性值添加到rails中的表記錄

Question

我想在product #create action時插入user_id。

如何在productController中插入user_id？

用戶只是模特。

這是products_controller.rb

  def create

    @user = current_user
    @product = Product.new(product_params, user_id: user_id)

    respond_to do |format|
      if @product.save

        format.html { redirect_to wardrobe_items_path, notice: 'Product was successfully created.' }
        format.json { render :show, status: :created, location: @product }
      else
        format.html { render :new }
        format.json { render json: @product.errors, status: :unprocessable_entity }
      end
    end
  end

產品表

class AddUserIdToProducts < ActiveRecord::Migration
  def change
    add_column :products, :user_id, :string
  end
end

Answer 1

做這個

@product = Product.new(product_params)
@product.user_id = current_user.id

Answer 2

做這個...

def create

    @user = current_user
    @product = Product.new(product_params)
    @product.user_id = current_user.id
    respond_to do |format|
      if @product.save

        format.html { redirect_to wardrobe_items_path, notice: 'Product was successfully created.' }
        format.json { render :show, status: :created, location: @product }
      else
        format.html { render :new }
        format.json { render json: @product.errors, status: :unprocessable_entity }
      end
    end
end
