has_one关联的未定义方法错误

我有一个Shop模型和一个User模型。逻辑是用户可以拥有一个商店,而商店可以具有一个与之关联的用户,因此我使用的是has_one: shop关联。

但是在为新用户创建新商店时出现此错误

  

#<\ User:0x007f6f30659068>的未定义方法'shops'是什么意思?商店商店=

我不明白怎么了。我确定我一定做过一些愚蠢的事情,这是我的代码:

class ShopsController < ApplicationController
  before_action :authenticate_user!, except: [:index, :show]

  def new
    @shop = current_user.shop.build
  end

  def create
    @shop = current_user.shops.build(shop_params)
    @shop.user = current_user

    respond_to do |format|
      if @shop.save
        format.html { redirect_to @shop, notice: 'Shop was successfully created.' }
        format.json { render :show, status: :created, location: @shop }
      else
        format.html { render :new }
        format.json { render json: @shop.errors, status: :unprocessable_entity }
      end
    end
  end

  private    
    def shop_params
      params.require(:shop).permit(:name, :description, :imageshop, :location, :web, :email, :phone, :business_type, :category)
    end
end

class Shop < ApplicationRecord
  mount_uploader :imageshop, ImageUploader
  belongs_to :user
end

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable
  has_many :products, dependent: :destroy
  has_one :shop
end

我认为您需要更改

hexString

@shop = current_user.shops.build(post_params)

这是因为您指定了一个用户可以拥有一个商店。

希望有帮助!
