简单形式不保存嵌套属性

Question

我有一个用户模型。使用设计。当我创建用户时我想通过嵌套形式创建一个场所。

我换成了simple_form。

我确信这是一个简单的错误并且我错过了一些东西

我在场地上收到未经许可的参数，这让我抓狂，请帮忙

型号

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :masqueradable, :database_authenticatable, :registerable, :recoverable, :rememberable, :validatable, :omniauthable

  has_one_attached :avatar
  has_person_name
  has_many :venues, inverse_of: :user
  accepts_nested_attributes_for :venues

end

    class Venue < ApplicationRecord
        belongs_to :user
    end

控制器

class ApplicationController < ActionController::Base
  include Pundit

  protect_from_forgery with: :exception

  before_action :configure_permitted_parameters, if: :devise_controller?
  before_action :masquerade_user!

      devise_parameter_sanitizer.permit(:account_update, keys: [:name, :avatar])
    end
end

class Users::RegistrationsController < Devise::RegistrationsController
  # before_action :configure_sign_up_params, only: [:create]
  # before_action :configure_account_update_params, only: [:update]

  # GET /resource/sign_up
  def new
     @user = User.new
     @user.venues.build
  end

class VenuesController < ApplicationController
  before_action :set_venue, only: %i[ show edit update destroy ]

    @venue = Venue.new(venue_params)

    respond_to do |format|

        format.html { redirect_to @venue, notice: "Venue was successfully created." }
        format.json { render :show, status: :created, location: @venue }
      else
        format.html { render :new, status: :unprocessable_entity }
        format.json { render json: @venue.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /venues/1 or /venues/1.json
  def update
    respond_to do |format|
      if @venue.update(venue_params)
        format.html { redirect_to @venue, notice: "Venue was successfully updated." }
        format.json { render :show, status: :ok, location: @venue }
      else
        format.html { render :edit, status: :unprocessable_entity }
        format.json { render json: @venue.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /venues/1 or /venues/1.json
  def destroy
    @venue.destroy
    respond_to do |format|
      format.html { redirect_to venues_url, notice: "Venue was successfully destroyed." }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_venue
      @venue = Venue.find(params[:id])
    end

    # Only allow a list of trusted parameters through.
    def venue_params
      params.require(:venue).permit(:name)
    end
end

    <div class="text-center">
      <%= render "devise/shared/links" %>

Answer 1

这是一个简单的复数错误。您的模型 has_many :venues 和 accepts_nested_attributes_for :venues 因此您需要在表单中使用复数形式 :venues：

<%= f.simple_fields_for :venues do |v| %>
  <div class="mb-3">
      <%= v.label :name %>
      <%= v.input :name, autofocus: false, class: 'form-control' %>
  </div>
<% end %>

你需要加入白名单venues_attributes:

def configure_permitted_parameters
  devise_parameter_sanitizer.permit(:sign_up, keys: [:name, venues_attributes: [:name, :id]])
  devise_parameter_sanitizer.permit(:account_update, keys: [:name, :avatar])
end
