Re: Using WebAPIResource from Javascript - need Backbone.Model.extend example

[Christian Hammond]

Hi Eric,

The `model` and `uri_object_key` are configurations for a resource's
implementation, and aren't related to the data provided by the caller.

The `model` attribute is optionally used to associate a WebAPIResource
subclass with a particular database model. If set, many of the operations
(GET requests to lists or to objects, DELETEs, etc.) are implemented for
you, but otherwise, you have to implement those yourself (by overriding
get(), get_list(), delete(), etc.).

`uri_object_key` defines the name of the capture group in the URL's regex
that captures the iD used to look up the appropriate object (defined by
`model`) in the database.

You don't need to do anything with Backbone to make use of the API. a
$.post() should be fine. However, it sounds like maybe the WebAPIResource
isn't implemented fully.

Can you show me the code you've written, how you're calling into the API,
and what the results are when you do so? We can help you write the
WebAPIResource to do what you need.

Christian

Re: diffviewer_filediff Table in DB

[john levin]

Thanks Alot David. You Saved my Time.

A colleague of mine wrote a sql quicky based on your input and we achieved 
the result.

select D.id,D.status,A.source_file from diffviewer_filediff A , 
diffviewer_diffset B , diffviewer_diffsethistory C,reviews_reviewrequest D 
where A.diffset_id = B.id and B.history_id = C.ID and  D.diffset_history_id 
= C.id and D.id = 57; (57 is the review id)
