您好我有一个简单的应用程序，我希望用户在注册时创建公司。我非常重要的是，用户在注册时创建公司，因此在注册控制器中创建方法
因此，注册表单有4个字段：电子邮件，公司名称，密码和密码确认。
我无法在用户注册表单上查看导致错误的原因。
1 error prohibited this user from being saved:
Company must exist
我的表格如下：
<h2>Sign up</h2>
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true %>
</div>
<div class="field">
<%= f.label :company %><br />
<%= f.text_field :company %>
</div>
<div class="field">
<%= f.label :password %>
<% if @minimum_password_length %>
<em>(<%= @minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "off" %>
</div>
<div class="field">
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation, autocomplete: "off" %>
</div>
<div class="actions">
<%= f.submit "Sign up" %>
</div>
<% end %>
<%= render "devise/shared/links" %>

我新安装了rails 5.02，其中包括两个型号公司和用户（由设计生成）
class Company < ApplicationRecord
has_many :users
end
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
belongs_to :company
accepts_nested_attributes_for :company
end
注意我已尝试使用和不使用接受嵌套属性
我的控制器如下
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_action :configure_permitted_parameters, if: :devise_controller?
def configure_permitted_parameters
devise_parameter_sanitizer.permit(:sign_up, keys: [:fullname,
company: [:name]])
end
end
class RegistrationsController < Devise::RegistrationsController
def create
super
if resource.save
puts params.inspect
@company = Company.create(name: params[:user][:company])
resource.update(company_id: @company.id)
# resource.company_id = @company.id
# resource.save
end
end
protected
def update_resource(resource, params)
resource.update_without_password(params)
end
end
class UsersController < ApplicationController
def index
@users = User.all
end
def user_params
params.require(:user).permit(:fullname, keys: [company: [:name]])
end
end
我的路线如下
Rails.application.routes.draw do
devise_for :users,
:path => '',
:path_names => {:sign_in => 'login',
:sign_out => 'logout',
:edit => 'profile'},
:controllers => {:registrations => 'registrations'}
root 'pages#home'
resources :companies

end
我的架构看起来像是
# This file is auto-generated from the current state of the database. Instead
# of editing this file, please use the migrations feature of Active Record to
# incrementally modify your database, and then regenerate this schema definition.
#
# Note that this schema.rb definition is the authoritative source for your
# database schema. If you need to create the application database on another
# system, you should be using db:schema:load, not running all the migrations
# from scratch. The latter is a flawed and unsustainable approach (the more migrations
# you'll amass, the slower it'll run and the greater likelihood for issues).
#
# It's strongly recommended that you check this file into your version control system.
ActiveRecord::Schema.define(version: 20170711100448) do
# These are extensions that must be enabled in order to support this database

end
我还在github上添加了app，只是你需要更多信息：here

未经许可的参数：公司
根据您的模型和configure_permitted_parameters的外观，您将表单设置为错误。您有accept_nested_attributes_for :company，因此您应该使用fields_for
<h2>Sign up</h2>
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true %>
</div>
<%= f.fields_for :company do |c| %>
<div class="field">
<%= c.label :name %><br />
<%= c.text_field :name %>
</div>
<% end %>
<div class="field">
<%= f.label :password %>
<% if @minimum_password_length %>
<em>(<%= @minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "off" %>
</div>
<div class="field">
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation, autocomplete: "off" %>
</div>
<div class="actions">
<%= f.submit "Sign up" %>
</div>
<% end %>
<%= render "devise/shared/links" %>
1错误禁止此用户被保存：
公司必须存在
在 Rails 5.x 中，belongs_to关联默认为 。但是，您可以使用optional :true来消除错误
belongs_to :company, optional: true

我在这里做的是在用户上生成迁移，如下所示：
rails g migration AddColumnToUser company:string
然后使用rake db:migrate
并将:company添加到允许的Devise参数中，以便您可以通过表单访问它。
