I really couldn’t tell you; it appears that you’re passing the object you want encoded to the ExtJsonEncoder incorrectly. Are you doing anything odd like using an asterisk to pass values?

Hi! I’m trying to implement your code on my application, putting ExtJsonEnconder and json on my utils file and treetojson at my views.py and I’m getting this error:

__init__() got an unexpected keyword argument ‘use_decimal’

Do you have any idea what is happening?

Cheers

Rogério

Thanks, fixed it. Dammit, I know I fixed that in the test code, too, so how it wound up in the post… Sigh. So annoying.

No biggy . Also it looks like you have a typo:

{‘cls’, ExtJsonEncoder}

That’s invalid, it should be a colon like so:

{‘cls’: ExtJsonEncoder}

Otherwise it works like a charm.

That’s true. Someone else commented on that on my personal blog, and I pointed out that this technique works with Pylons and Webware just as readily. It’s just that I was doing this in a Django-ish context. I should amend it to mention that this works with any implementation of simplejson.

While this is very handy (I just had to do the same thing last week), it’s inaccurate to call it “Django’s simplejson”. simplejson is a third party library that just happens to be included in Django since it’s full stack and tries to bundle all the dependencies.
