问题是这样的:
如果我使用默认注册控制器,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,我会收到错误
字段的设计错误消息和hasError
div包装器
在registrations controller
操作的edit
中,我将值归因于变量@myvar={2, 3}
此变量用于registrations_edit
视图
每当用户更新失败时,我的no method .each for nil
@myvar
我应该如何声明我的视图变量,以便即使更新表单失败也可以访问它们?!
我试过了:
强制控制器无论如何都重定向到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
这会产生问题,因为设计验证不再起作用

我的注册编辑:
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| %>
<%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 %>

注册管理员:

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 is_flashing_format?
flash_key = update_needs_confirmation?(resource, prev_unconfirmed_email) ?

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

如果你被重定向,所有的控制器实例变量都会被转储,所以除了在通过重定向传播的某个地方保存你需要的数据之外,没办法解决这个问题。其中一个地方是flash
消息(如果您需要一个字符串并只使用一次)。
另一种选择是将其存储在session
中并在另一侧进行拣选。
如果您在问题中粘贴registrations#edit
操作,我可以告诉您更多信息。
