Question

我的表单存在问题，因为在输入数据后，调用show方法时会得到Couldn't find Employeur without an ID。我认为这是由于我的嵌套资源。

以下是我的路线：

resources :users do
  resource: employeur
  resource: prestataire
end

我的用户控制器，一旦用户填写了表格，就会将其发送给我们：

class UsersController < ApplicationController

#TODO index user doit être suprimé quand inutile pour dev
  def index
    @users = User.all
  end

  def show
    @user = User.find(params[:id])
  end

  def new
    @user = User.new
  end

  # GET /users/1/edit
  def edit
    @user = User.find(params[:id])
  end

  # POST /users
  # POST /users.json
  def create
    @user = User.new(user_params)

    respond_to do |format|
      if @user.save
        if params[:commit] == 'Prestataire'
        format.html { redirect_to new_user_prestataire_path(user_id: @user), notice: "Renseignez vos informations d'employeur" }
        format.json { render action: 'show', status: :created, location: @user }
        else 
        format.html { redirect_to new_user_employeur_path(user_id: @user), notice: "Renseignez vos informations de prestataire" }
        format.json { render action: 'show', status: :created, location: @user }
        end
      else
        format.html { render action: 'new' }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /users/1
  # PATCH/PUT /users/1.json
  def update
    @user = User.find(params[:id])
    respond_to do |format|
      if @user.update(user_params)
        if params[:commit] == 'Prestataire'
        format.html { redirect_to new_user_prestataire_path(user_id: @user), notice: 'User was successfully updated.' }
        format.json { head :no_content }
        else 
        format.html { redirect_to new_user_employeur_path(user_id: @user), notice: "User was successfully updated." }
        format.json { head :no_content }
        end
      else
        format.html { render action: 'edit' }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /users/1
  # DELETE /users/1.json
  def destroy
    @user = User.find(params[:id])
    @user.destroy
    respond_to do |format|
      format.html { redirect_to users_url }
      format.json { head :no_content }
    end
  end

private
  def user_params
    params.require(:user).permit(:email, :password, :password_confirmation, :surname, :forename, :civility, :phone)
  end

end

我遇到麻烦的雇员表格：

<%= form_for [@user, @employeur] do |f| %>
  <% if @employeur.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@employeur.errors.count, "error") %> prohibited this employeur from being saved:</h2>

      <ul>
      <% @employeur.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :siren, 'Siren: ' %><br>
    <%= f.text_field :siren %>
  </div>
  <div class="field">
    <%= f.label :societe, 'Société: ' %><br>
    <%= f.text_field :societe %>
  </div>
  <div class="field">
    <%= f.label :code_postal, 'Code Postal: ' %><br>
    <%= f.text_field :code_postal %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

我的雇员控制器找不到我的雇员参数：

class EmployeursController < ApplicationController
  before_filter :load_user

  def index
    @employeurs = @user.employeur.all
  end


  def show
    @employeur = Employeur.find(params[:id])
  end

  def new
    @employeur = @user.build_employeur
  end

  def edit
    @employeur = Employeur.find(params[:id])
  end


  def create
    @employeur = @user.build_employeur(employeur_params)
    respond_to do |format|
      if @employeur.save
        format.html { redirect_to [@user, @employeur], notice: 'Employeur was successfully created.' }
        format.json { render action: 'show', status: :created, location: @employeur }
      else
        format.html { render action: 'new' }
        format.json { render json: @employeur.errors, status: :unprocessable_entity }
      end
    end
  end

  def update
  @employeur = Employeur.find(params[:id])
    respond_to do |format|
      if @employeur.update_attributes(employeur_params)
        format.html { redirect_to [@user, @employeur], notice: 'Employeur was successfully created.' }
        format.json { render action: 'show', status: :created, location: @employeur }
      else
        format.html { render action: 'new' }
        format.json { render json: @employeur.errors, status: :unprocessable_entity }
      end
    end
  end


def destroy
  @employeur = Employeur.find(params[:id])
  @employeur.destroy
  respond_to do |format|
    format.html { redirect_to @user }
    format.json { head :no_content }
  end
end

private
  def load_user
    @user = User.find(params[:user_id])
  end

  def employeur_params
    params.require(:employeur).permit(:siren, :societe, :code_postal)
  end

end

我决定编辑我的第一篇文章，添加与@Sirius ROR的雇员相关的所有路线：

   user_employeur POST   /users/:user_id/employeur(.:format)              em

ployeurs＃创建 new_user_employeur GET /users/:user_id/employeur/new(.:format）em ployeurs＃新 edit_user_employeur GET /users/:user_id/employeur/edit(.:format）em ployeurs＃编辑 GET /users/:user_id/employeur(.:format）em ployeurs＃秀 PATCH /users/:user_id/employeur(.:format）em ployeurs＃更新 PUT /users/:user_id/employeur(.:format）em ployeurs＃更新删除/users/:user_id/employeur(.:format）em ployeurs＃破坏

我也做了一个重大改变：

变成了：

因为我对我的雇主模型做了重大改变：

class Employeur < ActiveRecord::Base
  model_name.instance_variable_set :@route_key, 'employeur'
  belongs_to :user
  has_many :projets, as: :projetable
  has_many :prestataires, through: :projets
  has_many :offres, through: :projets
  has_many :feedbacks, through: :projets
  validates :siren, :societe, :code_postal, presence: true
end

根据我最终在互联网上找到的内容，第一行涉及网址问题。尽管有这样的改变，我仍然得到完全相同的错误：找不到没有ID的Employeur。

这也是我的用户模型：

class User < ActiveRecord::Base
  has_one :prestataire
  has_one :employeur
  accepts_nested_attributes_for :employeur, allow_destroy: true
  has_secure_password
end

Answer 1

尝试从form_for中删除url选项作为表单，以自动构建帖子网址

<%= form_for [@user, @employeur] do |f| %>

这一定很有效。

使用嵌套和单一资源的form_for [@ user，@ instloyeur]之后的ID问题
