当我的帐户更新失败时,为什么设计我将我重定向到 /users 而不是 /users/edit?

Why does devise me redirect me to /users instead of /users/edit when my account update fails?

问题是这样的:

如果我使用默认的注册控制器,我会被重定向:

因为默认控制器更新操作如下所示:

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 默认设置为 root

如果更新失败我收到设计错误消息和hasError div错误字段的包装器

在我的 registrations controller 中,在 edit 操作中,我将值归因于一个变量 @myvar={2, 3}

此变量用于registrations_edit 视图

只要用户更新失败,我的@myvar

就会收到错误no method .each for nil

我应该如何声明我的视图变量,以便即使在更新表单失败时也可以访问它们?!

我试过:

无论如何都强制控制器重定向到edit视图:

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

这造成了问题,因为设计验证不再有效

我的注册编辑:

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

我的看法:

<% 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 %>

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
    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

如果您被重定向,所有控制器实例变量都会被转储,因此除了将您需要的数据保存在通过重定向传播的某个地方之外,没有办法解决这个问题。一个这样的地方是在 flash 消息中(如果你需要一个字符串并且只使用它一次)。

另一种选择是将其存储在 session 中并在另一侧提取。

如果您将 registrations#edit 操作粘贴到问题中,我可以告诉您更多信息。

你可以试试这个;-

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
