I would argue the contrary.. Maybe you can give some examples? - Are you overriding in the correct places? In the beginning with TastyPie, I would override get_detail and such, often when I should have been overriding obj_get instead..

We are using TastyPie in production on a pretty large site and I've been super happy with it. We have custom fields, custom auth, custom base classes for resources where the underlying data store are non django models, security is very granular (with minimal code overhead) and overall its been a blessing to extend and override. One thing I like in particular is how you can reuse nested Resource definitions, e.g. define a UserResource once and reuse it everywhere a model/resource has a FK to user and you get correct response output. Saves lots of time and gets you a correct, secure implementation.
