如何应用自定义的Bootstrap消息错误设计? [英] How to apply customized Bootstrap messages errors to devise?
问题描述
我对我的Rails4应用程序中的所有邮件应用Bootstrap3错误样式,这里(源) )
I'm applying Bootstrap3 errors style to all messages in my Rails4 app, here (source)
def bootstrap_class_for flash_type
{ success: "alert-success", error: "alert-error", alert: "alert-warning", notice: "alert-info" }[flash_type] || flash_type.to_s
end
def flash_messages(opts = {})
capture do
flash.each do |msg_type, message|
concat(content_tag(:div, message, class: "alert #{bootstrap_class_for(msg_type)} fade in") do
concat content_tag(:button, 'x', class: "close", data: { dismiss: 'alert' })
concat message
end)
end
nil
end
end
在同一时间,我试图应用相同的样式Devise错误消息,但它不工作。
例如;在[views / devise / registration / new]中,您将看到<%= devise_error_messages!
In the same time I'm trying to apply same style to Devise error messages but it does not work.
For example; within [views/devise/registration/new] you see <%= devise_error_messages! %>
which it shows error messages without style.
如何应用Bootstrap风格(上面)来设计错误消息?
How could I apply Bootstrap style (above) to devises error messages?
推荐答案
覆盖 devise_error_messages!
帮助方法
app / helpers / devise_helper.rb
app/helpers/devise_helper.rb
module DeviseHelper
def devise_error_messages!
return "" if resource.errors.empty?
messages = resource.errors.full_messages.map { |msg| content_tag(:li, msg) }.join
html = <<-HTML
<div class="alert alert-error alert-block">
#{messages}
</div>
HTML
html.html_safe
end
没有使用任何css类,因此我们使用 alert-error
类,而您可以使用您的自定义类
Where the devise doesn't used any css class so we use alert-error
class instead you can use your custom class
<div class="alert #{boostrap_class_for(:error)} alert-block">
