为什么在我的帐户更新失败时，我会将我重定向到/ users而不是/ users / edit？ [英] Why does devise me redirect me to /users instead of /users/edit when my account update fails?

问题描述

问题是这样的：

如果我使用默认注册控制器，我被重定向：

• / users / edit 到根，当用户更新成功


• 更新失败 / users / edit 到 / users

因为默认的控制器更新操作如下所示：

 如果resource_updated 
 sign_in resource_name，resource，bypass： true 
 respond_with资源，位置：after_update_path_for（资源）
 else 
 clean_up_passwords资源
 respond_with资源
结束
  

after_update_path_for 默认设置为根

如果更新失败，我会收到设计错误消息和 hasError div包装器，错误

在我的注册控制器编辑动作我将值归因于变量 @ myvar = {2，3}

此变量用于 registrationrations_edit 视图

无论何时用户更新失败，我收到错误没有方法.each为nil 为我的 @myvar

我应该如何声明我的视图变量，即使在更新表单失败时也可以访问？

我试过：

强制控制器重定向到编辑查看无论什么：

 如果resource_updated 
 sign_in resource_name，resource，bypass：true 
 redirect_to edit_user_registration_path 
 else 
 clean_up_passwords资源
 redirect_to edit_user_registration_path 
 end 
  

由于设计验证不再工作

我的注册e dit：

  def edit 
 @images = Dir.glob（public / assets / images / users / current_user.id} / med / *）
 end 
  

我的观点：

 <％img_paths = Array.new％> 
<％@ images.each do | image | ％GT; 
<％img_paths.push（[
''，
/assets/images/users/#{current_user.id}/original/#{image.split('/'） .last}，
 {'data-img-src'=>/ assets / images / users /＃{current_user.id} / med /＃{image.split（'/' } 
]）％> 
<％end％>

注册控制器：

  class Users :: RegistrationsController< Devise :: RegistrationsController 
 
 def edit 
 @images = Dir.glob（public / assets / images / users /＃{current_user.id} / med / *）
 end 
 
 def update 
如果params [：image_file_path] 
 ff = File.open（public /+ params [：image_file_path]）
 resource.image = ff 
 resource.save！ 
 end 
 self.resource = resource_class.to_adapter.get！（send（：current _＃{resource_name}）to_key）
 prev_unconfirmed_email = resource.unconfirmed_email if resource.respond_to？（ unconfirmed_email）
 
 resource_updated = resource.update_with_password（account_update_params）
生成资源如果block_given？ 
如果resource_updated 
如果is_flashing_format？ 
 flash_key = update_needs_confirmation？（resource，prev_unconfirmed_email）？ 
：update_needs_confirmation：更新
 set_flash_message：notice，flash_key 
 end 
 sign_in resource_name，resource，bypass：true 
 respond_with资源，位置：after_update_path_for（资源）
 else 
 clean_up_passwords资源
 respond_with资源
结束

私人
 
 def sign_up_params 
 params.require（：user）.permit（：first_name，：last_name，：email，：password，：password_confirmation，：phone，：image，：address，，birthday）
 end 
 
 def account_update_params 
 params.require（：user）.permit（：first_name，：last_name，：email，：password，：password_confirmation，：phone，：image，：image_file_path，：address，，birthday）
 end 
 
 protected 
 
 def update_resource（resource，params）
 resource.update_without_password（params）
 end 
 
 def after_update_path_for（resource）
 edit_user_reg istration_path 
 end 
 
 end 
  

解决方案

您可以尝试这样做; -

  def update 
如果params [：image_file_path] 
 ff = File.open（public /+ params [：image_file_path]）
 resource.image = ff 
 resource.save！ 
 end 
 self.resource = resource_class.to_adapter.get！（send（：current _＃{resource_name}）to_key）
 prev_unconfirmed_email = resource.unconfirmed_email if resource.respond_to？（ unconfirmed_email）
 
 resource_updated = resource.update_with_password（account_update_params）
生成资源如果block_given？ 
如果resource_updated 
如果is_flashing_format？ 
 flash_key = update_needs_confirmation？（resource，prev_unconfirmed_email）？ 
：update_needs_confirmation：更新
 set_flash_message：notice，flash_key 
 end 
 sign_in resource_name，resource，bypass：true 
 respond_with资源，位置：after_update_path_for（资源）
 else 
 @images = Dir.glob（public / assets / images / users /＃{current_user.id} / med / *）
 
 clean_up_passwords资源
 
 respond_with资源
 end 
 end 
  

The problem is like this:

If I use the default registration controller I get redirected:

• /users/edit to root when user update succeeds
• /users/edit to /users when update fails

Because the default controller update action looks like this:

if resource_updated
  sign_in resource_name, resource, bypass: true
  respond_with resource, location: after_update_path_for(resource)
else
  clean_up_passwords resource
  respond_with resource
end

after_update_path_for is set by default to root

If update fails I get the devise error messages and hasError div wrappers for the fields with error

In my registrations controller in the edit action I attribute values to a variable @myvar={2, 3}

This variable is used in the registrations_edit view

Whenever user update fails I get error no method .each for nil for my @myvar

How should I declare my view variables such that they are accessible even when update form fails?!

I have tried:

Forcing the controller to redirect to edit view no matter what:

if resource_updated
  sign_in resource_name, resource, bypass: true
  redirect_to edit_user_registration_path
else
  clean_up_passwords resource
  redirect_to edit_user_registration_path
end

This created problems because devise validations do not work anymore

Edit-------

My registrations edit:

def edit
  @images = Dir.glob("public/assets/images/users/#{current_user.id}/med/*")
end

My view:

<% img_paths = Array.new %>
  <% @images.each do |image| %>
  <%img_paths.push([
    '',
    "/assets/images/users/#{current_user.id}/original/#{image.split('/').last}",
    {'data-img-src'=>"/assets/images/users/#{current_user.id}/med/#{image.split('/').last}"}
    ])%>
  <% end %>

Edit-----

Registration controller:

class Users::RegistrationsController < Devise::RegistrationsController

  def edit
    @images = Dir.glob("public/assets/images/users/#{current_user.id}/med/*")
  end

  def update
    if params[:image_file_path]
      ff = File.open("public/"+params[:image_file_path])
      resource.image = ff
      resource.save!
    end
    self.resource = resource_class.to_adapter.get!(send(:"current_#{resource_name}").to_key)
    prev_unconfirmed_email = resource.unconfirmed_email if resource.respond_to?(:unconfirmed_email)

    resource_updated = resource.update_with_password(account_update_params)
    yield resource if block_given?
    if resource_updated
      if is_flashing_format?
        flash_key = update_needs_confirmation?(resource, prev_unconfirmed_email) ?
          :update_needs_confirmation : :updated
        set_flash_message :notice, flash_key
      end
      sign_in resource_name, resource, bypass: true
      respond_with resource, location: after_update_path_for(resource)
    else
      clean_up_passwords resource
      respond_with resource
    end
  end


  private

  def sign_up_params
    params.require(:user).permit(:first_name, :last_name, :email, :password, :password_confirmation, :telephone, :image, :address, :birthday)
  end

  def account_update_params
    params.require(:user).permit(:first_name, :last_name, :email, :password, :password_confirmation, :telephone, :image, :image_file_path, :address, :birthday)
  end

  protected 

  def update_resource(resource, params)
    resource.update_without_password(params)
  end

  def after_update_path_for(resource)
    edit_user_registration_path
  end

end

解决方案

You can try this;-

def update
    if params[:image_file_path]
      ff = File.open("public/"+params[:image_file_path])
      resource.image = ff
      resource.save!
    end
    self.resource = resource_class.to_adapter.get!(send(:"current_#{resource_name}").to_key)
    prev_unconfirmed_email = resource.unconfirmed_email if resource.respond_to?(:unconfirmed_email)

    resource_updated = resource.update_with_password(account_update_params)
    yield resource if block_given?
    if resource_updated
      if is_flashing_format?
        flash_key = update_needs_confirmation?(resource, prev_unconfirmed_email) ?
          :update_needs_confirmation : :updated
        set_flash_message :notice, flash_key
      end
      sign_in resource_name, resource, bypass: true
      respond_with resource, location: after_update_path_for(resource)
    else
    @images = Dir.glob("public/assets/images/users/#{current_user.id}/med/*")

      clean_up_passwords resource

      respond_with resource
    end
  end
