一个迭代开发中的网站难免存在bug,出bug的时候客户体验就很不好了,为解决此问题,可以在class error产生的时候,触发跳转到统一提示页面,并给开发人员发邮件报错误信息,提高测试能力和用户体验。以下是核心方法;在applicationcontroller中添加如下代码,不同rails版本的class error略有变化。
复制代码 代码如下:
ar_error_classes = [activerecord::recordnotfound, activerecord::statementinvalid]
error_classes = [nameerror, nomethoderror, runtimeerror,
actionview::templateerror,
activerecord::staleobjecterror, actioncontroller::routingerror,
actioncontroller::unknowncontroller, abstractcontroller::actionnotfound,
actioncontroller::methodnotallowed, actioncontroller::invalidauthenticitytoken]
access_denied_classes = [cancan::accessdenied]
if rails.env.production?
rescue_from *ar_error_classes, :with => :render_ar_error
rescue_from *error_classes, :with => :render_error
rescue_from *access_denied_classes, :with => :render_access_denied
end
#called by last route matching unmatched routes. raises routingerror which will be rescued from in the same way as other exceptions.
#备注rails3.1后actioncontroller::routingerror在routes.rb中最后加如下代码才能catch了。
#rails3下:match '*unmatched_route', :to => 'application#raise_not_found!'
#rails4下:get '*unmatched_route', :to => 'application#raise_not_found!'
def raise_not_found!
raise actioncontroller::routingerror.new("no route matches #{params[:unmatched_route]}")
end
def render_ar_error(exception)
case exception
when *ar_error_classes then exception_class = exception.class.to_s
else exception_class = 'exception'
end
send_error_email(exception, exception_class)
end
def render_error(exception)
case exception
when *error_classes then exception_class = exception.class.to_s
else exception_class = 'exception'
end
send_error_email(exception, exception_class)
end
def render_access_denied(exception)
case exception
when *access_denied_classes then exception_class = exception.class.to_s
else exception_class = "exception"
end
send_error_email(exception, exception_class)
end
