Json views

Hi *, I'm writing an API for my application, but I can't figure out how to behave with the json frontend, where I need to do something like @object.image.url. Should I write a .json view or there's some special method for this kind of problems ? I see to_json has a handy methods option that should call the method and put it in the output, but the problem here is that image is a Paperclip object (that contains also my S3 keys, so it's really not the case :p) and I need to call the url method. Suggestions ?

In case you decide that JSON views are what you want, have a look at a (trivial) template handler I wrote to help with just that

Nice, thanks a lot. What do I have to include to use it ? Right now by following the example my only result is to have a string in return.

You can install the handler either as a plugin using script/plugin or as a gem. In the latter case you have to add

  config.gem "mschuerig-ruby_template_handler",     :lib => 'ruby_template_handler'

to config/environment.rb.

Right now by following the example my only result is to have a string in return.

Well, what else do you want to return? The body of your response is always going to be a string, in this case a string in JSON format.
