[Rails] Re: Need help : How to render HTML inside of a JSON request
Thanks, Jonathan. First off, I inherited this code base and I realize that there is a better solution... specifically to do a request with update. The request ask for json because they return both data elements which are used in the page and an html block as a replacement for a section. If there were only one call... I would just fix it by hand, but this approach has been used in multiple places in the code base. They make a call that constructs a json object, and one element in it is a string of html to replace a div. Unfortunately, when we call render_string -- now the render wont look for .html.erb objects. I've tried adding :content_type=:html to the render call, to no avail. I've also tried adding Mime::HTML and 'text/html' as :content_type parameters. I think I just need to temporarily override the request content type during rendering, but I can't figure out how.

[Rails] Re: Need help : How to render HTML inside of a JSON request
Bah, you know what, ignore me. I just realized you're asking about _partial_ specifically, and now I realize the solution isn't as clear. And I know why you might want an html partial in a js response, because I do that myself. :) And now I see that I'll have to deal with this when I upgrade to rails 3 too. I suspect you just have to change the partial like you say, but I don't know if that would be considered a bug or not. Okay, I'm done in my marathon of answering quesitons in the listserv, now that I've started giving bad answers. :) -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Why are you returning .html from a ajax/json request from the client, anyway? Generally, ajax requests from the client get back javascript (or specifically json), not html! Rails is trying to help you with this general case, because you can have the same action that will return partial.html.erb if it's an html request, or partial.js.erb if it's an AJAX request. I forget exactly how Rails determines when the format is js, but I know if you're using any of the Rails helper methods for ajax callbacks, they definitely include a query param to tell Rails what's what. So you can change the render call like you say. Or you COULD rename the partial in the old way partial_name.erb, so Rails will use it for any format request. But that's kind of weird (and now i'm not entirely sure it'll work). Or you could reconsider why you want to return HTML (rather than js/json) to a js request in the first place. Or you could take a look at respond_to to see how you can return different views for different request types. http://api.rubyonrails.org/classes/ActionController/MimeResponds/InstanceMethods.html#M000368 -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
