Rails添加了新的设计视图 [英] Rails add new view to devise
问题描述
在我安装设备后，我已经用此命令生成了视图。
I have generated views with this command after I installed devise
rails generate devise:views
，我通过
class RegistrationsController < Devise::RegistrationsController
def sign_up2
end
end
并且更新的route.rb与
And updated routes.rb with
devise_for :users, :controllers => { :registrations => "registrations" }
我预计会看到
/users/sign_up2
但我看不到它
这里的路线设计
but I don't see it And here routes for devise
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy
user_password POST /users/password(.:format) devise/passwords#create
new_user_password GET /users/password/new(.:format) devise/passwords#new
edit_user_password GET /users/password/edit(.:format) devise/passwords#edit
PATCH /users/password(.:format) devise/passwords#update
PUT /users/password(.:format) devise/passwords#update
cancel_user_registration GET /users/cancel(.:format) registrations#cancel
user_registration POST /users(.:format) registrations#create
new_user_registration GET /users/sign_up(.:format) registrations#new
edit_user_registration GET /users/edit(.:format) registrations#edit
PATCH /users(.:format) registrations#update
PUT /users(.:format) registrations#update
DELETE /users(.:format) registrations#destroy
但我想要一个新的视图和路由
But I would like a new view and route
更新：加载视图时
出现
Update: issue when I load view
First argument in form cannot contain nil or be empty
p>
in this line
<%= form_for(resource, :as => resource_name,:html => { :class => "form-horizontal col-sm-12",:role=>"form"}, :url => user_registration_path(resource_name)) do |f| %>
推荐答案
调用 devise_scope 阻止并声明您的自定义路线：
Invoke a devise_scope block and declare your custom route within:
devise_for :users, :controllers => { :registrations => "registrations" }
devise_scope :user do
get "users/sign_up2"=> "users/registrations#sign_up2", :as => "sign_up2_registration"
end
配置路径提供了 devise_scope 的以下说明：
如果您需要更深入的定制，例如除/ users / sign_in之外还允许/ sign_in，您需要做的就是创建路由正常，并将它们包装在路由器中的devise_scope块中
If you have the need for more deep customization, for instance to also allow "/sign_in" besides "/users/sign_in", all you need to do is to create your routes normally and wrap them in a devise_scope block in the router
以前，Devise允许将自定义路由作为块传递到code> devise_for ，但此行为已被弃用 。
Previously, Devise allowed custom routes to be passed as a block to devise_for, but this behavior has been deprecated.
更新：
要解决表单中的参数不能包含nil或为空错误，您需要确保您的自定义 sign_up2 操作正确设置e 资源变量。假设你想模仿注册/新的动作，你可以做一些类似于以下的事情：
To address the First argument in form cannot contain nil or be empty error, you need to ensure that your custom sign_up2 action is properly setting the resource variable. Assuming you want to mimic the registrations/new action, you can do something akin to the following:
def sign_up2
build_resource({})
respond_with self.resource
end
这样可以确保视图中的资源变量不是 nil 不会抛出你正在目睹的异常。
This ensures that the resource variable in your view is not nil and will not throw the exception you're currently witnessing.
另外，根据你想要表现的行为，您可以在自定义控制器动作中设置自己的实例变量，然后传递它作为您的 form_for 标签的资源：
# app/controllers/users/registrations_controller.rb
def sign_up_2
@new_registrant = Registrant.new
end
# app/views/users/sign_up2.html.erb
<%= form_for(@new_registrant, :as => resource_name,:html => { :class => "form-horizontal col-sm-12",:role=>"form"}, :url => user_registration_path(resource_name)) do |f| %>
但是，如果您遵循这种方法，您应该考虑为什么你需要把它转载给Devise。默认情况下，Devise通过 build_resource 函数分配资源变量。如果你要覆盖/绕过这个函数，你应该考虑将这个完整的功能从Devise抽象出来，因为你完全绕过它的默认行为。
However, if you follow this approach, you should consider why you need to roll this into Devise. Devise, by default, assigns the resource variable via the build_resource function. If you're going to override/bypass this function, you should consider abstracting this entire functionality out of Devise since you're totally circumventing its default behavior.
