Backbonejs and rails issues w/ Backbone.sync

[Jeff Deville]

I'm having trouble getting BackboneJS's syncing to work with my rails3 backend. I'm trying to use the JSON posts, and it sends my data in {_json: {}}. The problem with this is that the authenticity_token is then not included. (Or perhaps it is, but in the _json parameter). Rails won't deserialize it, even though I've forced the ajax options: {contentType: 'application/json', dataType: "json"}.

I posted the question to stack overflow here, if you'd like to bump up your rep, I'll gladly upvote.

Hey Jeff,

If the authenticity token is your problem, this will fix it: https://github.com/Maciek416/BackboneRailsAuthTokenAdapter

Hi Ed, thanks but that was not the problem. Or rather, that doesn't fix it when you are not in emulateHTTP mode, because backbone sticks the JSON doc in a param called _json. The auth token is in there but rails isn't pulling it out

Sounds to me like something else is going on. We use Backbone heavily here at
PipelineDeals and I have not run into a case where Backbone sends data inside of a hash entry _json.

Where does _json get generated?

Hi Grant,
I'm not using most of Backbone, just the Sync component (I'm mixing and matching a few frameworks), and was calling in to it myself. I think the problem was that I wasn't stringifying the JSON. Once that didn't work, I started messing with $.ajax options extensively, and went down a rabbit hole.

I got things working now though. Thanks.
