我一直在努力争取这个。我有一个Rails4 / Devise 3.1应用程序,系统中有两个用户:
和一个设计用户可以通过多态:profile
关联成为研究生或雇主。我有毕业生通过/graduate/sign_up
路径和雇主通过/employer/sign_up
路径注册,这两条路径都路由到同一/views/devise/registrations/new.html.erb
视图(因为他们的注册表格几乎相同 - 电子邮件和密码)。一切正常,除非出现验证错误,RegistrationsController#create.respond_with resource
始终将两种用户类型重定向到/users
路径,我需要将它们重定向回原来的位置,例如:分别为/graduate/sign_up
或/employer/sign_up
。我尝试用respond_with
替换redirect_to
,但最终我丢失了带有相关错误消息的资源对象。任何人都知道如何做到这一点?
这些是我的模特:
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
belongs_to :profile, polymorphic: true
end
class Graduate < ActiveRecord::Base
has_one :user, as: :profile
end
class Employer < ActiveRecord::Base
has_one :user, as: :profile
end
注册控制器:
class RegistrationsController < Devise::RegistrationsController
def create
build_resource sign_up_params
user_type = params[:user][:user_type]
# This gets set to either 'Graduate' or 'Employer'
child_class_name = user_type.downcase.camelize
resource.profile = child_class_name.constantize.new
if resource.save
if resource.active_for_authentication?
set_flash_message :notice, :signed_up if is_navigational_format?
sign_up(resource_name, resource)
respond_with resource, :location => after_sign_up_path_for(resource)
else
set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
expire_session_data_after_sign_in!
respond_with resource, :location => after_inactive_sign_up_path_for(resource)
end
else
clean_up_passwords(resource)
respond_with resource
end
end
end
注册视图(同样适用于毕业生和雇主):
<h2>Sign up</h2>
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div><%= f.label :email %><br />
<%= f.email_field :email, :autofocus => true %></div>
<div><%= f.label :password %><br />
<%= f.password_field :password %></div>
<div><%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation %></div>
<%= hidden_field resource_name, :user_type, value: params[:user][:user_type] %>
<div><%= f.submit "Sign up" %></div>
<% end %>
<%= render "devise/shared/links" %>
这些是我的路线:
devise_for :users, :controllers => { :registrations => 'registrations' }
devise_scope :user do
match 'graduate/sign_up', to: 'registrations#new', user: { user_type: 'graduate' }, via: [:get]
match 'employer/sign_up', to: 'registrations#new', user: { user_type: 'employer' }, via: [:get]
end
root to: 'home#index'
耙路线的输出;

Apparently,如果您有一个名为的现有模板,则忽略:location
参数,在这种情况下,#index。我仍然不明白为什么当资源上有错误时,Devise会重定向到#index或#show。
我会在发现更多信息时更新此答案。
答案 1 :(得分:3)
调用respond_with
将呈现该资源的默认操作。我认为这是index
动作(/ users /),因此是重定向的原因。
我认为您要做的是代替new
动作。请尝试以下方法:
if resource.save
...
else
clean_up_passwords(resource)
render :action => 'new'
end
答案 2 :(得分:0)
对于respond_with,对于html响应 - 如果请求方法是get,则引发异常但是对于其他请求(例如发布响应)取决于资源是否有任何验证错误(即假设尝试已经用于保存资源,例如通过创建操作) -
如果没有错误,即资源已成功保存,则 响应重定向到资源,即显示操作。
如果存在验证错误,则响应会呈现默认操作, 这是:新邮件请求或:编辑补丁或放置。

对于您的情况,render 'view_path'
代替respond_with
块的内容应该有效。
