让我们假设您有两种特定类型的用户，即雇员和prestataires。首先，您使用一般信息（姓名，电子邮件等）填写用户表单。然后，您可以在prestataire或employeur表单之间进行选择，这将保存用户表单并将您重定向到题字的第二部分。雇员和prestataires模型都与用户具有belongs_to关系。
使用下面的代码，我已经能够创建并保存用户表单，被重定向到employeesur或prestataire表单。然而，当我创建一个employeeur时，我得到一个错误：＃的未定义方法`users'，尽管我的嵌套路由：
resources :users do
resources :employeurs
resources :prestataires
end
这是我的用户表单和控制器：
<%= form_for(@user) do |f| %>
<% if @user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@user.errors.count, "error") %> prohibited this user from being saved:</h2>
<ul>
<% @user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :civility, 'Titre de civilité: ' %><br>
<%= f.text_field :civility %>
</div>
.
.
.
<div class="actions">
<%= f.submit "Employeur" %>
<%= f.submit "Prestataire" %>
</div>
<% end %>
def create
@user = User.new(user_params)
用户控制器的这一部分创建一个实例并重定向到employeur或prestataire表单：
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
雇员控制员：
class EmployeursController < ApplicationController
def index
@employeurs = Employeur.all
end
# GET /projets/1
# GET /projets/1.json
def show
end
def new
@user = User.find(params[:user_id])
@employeur = @user.build_employeur
end
# GET /projets/1/edit
def edit
end
def create
@user = User.find(params[:user_id])
@employeur = @user.create_employeur(employeur_params)
end
def create_employeur
@user = User.find(params[:user_id])
@employeur = Employeur.new(employeur_params)
respond_to do |format|
if @employeur.save
format.html { redirect_to user_employeur_path(@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
private
def employeur_params
params.require(:employeur).permit(:siren, :societe, :code_postal)
end
end
并且就业形式：
<%= 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 %>
我对rails非常陌生，因此，我看不出任何错误......提前感谢您的帮助。
由于评论，我正在添加我的模型和回溯：
class User < ActiveRecord::Base
has_one :prestataire
has_one :employeur
has_secure_password
end
class Employeur < ActiveRecord::Base
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, presence: true, uniqueness: true
validates_associated :users
end
