[JSon] Rendering a json view and HTML characters

Hi there fellows !

I'm currently working on a JSon view and had to make my own view (for
simple ActiveSupport::JSON can't do the trick anymore).

The thing is, after my controller does this :

respond_to
  format.html
  format.json
end

It does use the correct view in the correct context. Yet, the json view
is filtered and the unsupported characters of HTML are modified.

So this is pretty much what I get :

{"created_at":"2011-07-28T15:38:36Z"}

When all I really wanted was :

{"created_at":"2011-07-28T15:38:36Z"}

What's up with that ? How may I prevent this filtering to happen ?

You're probably being tripped up by rails's automatic html escaping
What's in your view file?
It seems unlikely that you need to go down the root you're going down
- you can build whatever hash you need and then render it as json with
render :json => some_hash.

Well, the matter is quite complicated in fact. And I can't happen to
make render :json work for it does not render everything in an object
(at least, not something you add via instance_variable_set.

I have an object.
This object is joint with another object.
The two should be rendered in the same json object, but I figured that
would not be possible, so I rendered an array, containing themselves an
array with the first and the second object.
In some case, some objects have children : I'd like to render the array
of children in the same fashion (right after the object it concerns).

I can't think of a way to make that work without using a view.

You may not be able to make render :json => my_active_record_object
work, but (by definition) any piece of json is just a combination of
hashes, arrays, strings, numbers etc. Build up that hash in ruby, call
to_json on it and you should be away.

Right, I guess I was kinda tired yesterday.

Though, isn't it cleaner to keep the "interface" stuff in the views ?
Even if it's json, it still is nothing but a view to the javascript
part.

Also, even if I stopped using the view, if someone was to get the same
issue : the solution can be applying raw to the returns of
ActiveSupport::JSON.encode !
