[英]rails 3 - controller respond with javascript even through request format was text/html
I have a simple scenario where I want to request a page. 我有一个简单的场景,我想请求一个页面。 The request format is text/html.
请求格式为text / html。 If there is some error in the controller/action logic for that request, I want to get an error message.
如果该请求的控制器/操作逻辑中有错误,我想得到一条错误消息。 The twist is that I want this error message to be communicated to be with a javascript response type (ie no page refresh).
问题是我希望将此错误消息与javascript响应类型进行通信(即无页面刷新)。 If there are no errors, then I want the page to be loaded via the expected text/html response type.
如果没有错误,那么我希望通过预期的text / html响应类型加载页面。
Basically, I want two different response types depending on whether there is an error or not. 基本上,我要根据是否有错误来选择两种不同的响应类型。 Is this doable in rails 3?
这在rails 3中可行吗? If so, what is best practice?
如果是这样,什么是最佳做法?
A quick code sample would be much appreciated. 快速代码示例将不胜感激。
Thanks. 谢谢。
Sure it's doable! 当然可以!
I would do it like this: 我会这样做:
def some_action
# code
# more code
# implicit or explicit rendering of an html template
rescue Exception => ex
render :json => ex.to_json,
:content_type => 'application/json',
:layout => false
end
