[英]In Ruby on Rails, how to render JSON?
I tried the following to respond to AJAX and it works (in HAML): 我尝试了以下方法来响应AJAX,并且它可以工作(在HAML中):
- response.content_type = "application/json"
= render :text => array_data.to_json
but 但
- response.content_type = "application/json"
= render :json => array_data.to_json
doesn't work. 不起作用。 I thought I could use
我以为我可以用
= render :text => array_data.to_json
instead of the first 2 lines at the top? 而不是顶部的前2行?
= render :json => @object
(您不需要使用.to_json方法)
