Hopefully someone has already addressed this and I just haven't been able to find this.

I'm using Django 1.7 and am not able to install tastypie successfully. I have installed directly from the github repo thinking it may just be an issue with the pip version but I'm still having the same issue.

When I add tastypie to my installed apps, all of my manage.py commands fail with: RuntimeError: App registry isn't ready yet.

Is there a way to get tastypie running with python 2.7 + django 1.7 (dev)?

This is a rollup of the 1.8 atomic/transaction fixes from #1263 and a bunch of fixes for failing tests.

The whole thing needs a review, preferably by somebody with a stronger understanding of the related_resources tests and the save_related() method on Resource.

I got a green board to happen (https://travis-ci.org/django-tastypie/django-tastypie/builds/51335501), but I got there with a bit of fumbling through save_related() and I don't fully understand why I needed to do what I did.

WIP; updating to Django 1.11.

• Remove test matrix for 1.7, 1.9; we should support the most recent version (1.11), the most recent LTE (1.8), and run tests against dev (but allowed to fail).

I'm doing some profiling to speed up an API that I'm building with tastypie and am seeing ~ 70% (5 of 7 seconds) of my time being spent right now doing the deepcopy of the base fields in Resource.init when hydrating 5000 resources.

Given the general nature of the Resource object, I guess there are probably cases where you'd have a mutable object in the base Resource and need to create new ones for each instance but is that also true for ModelResources?

If I send patch data in functional test, I always get following exception:

My test case looks approximately like this:

def test_patch_valid_resource(self):
    contest = ContestFactory.create(created_by=self.user, type=self.type)

    new_name = 'Patched contest #1'

    patch_data = {
        'name': new_name,
    }

    self.assertHttpAccepted(self.api_client.patch('{0}{1}/'.format(self.uri, contest.id), data=patch_data))

    edited_contest = Contest.objects.get()

    self.assertEqual(Contest.objects.count(), 1)
    self.assertEqual(edited_contest.name, new_name)

From what I could trace, request object cuts request.raw_post_data to {"name": "Patch (in this particular test) for some reason. I'm not even sure if it's Tastypie error at all, but patch method is unusable in tests this way.

Trying to implement out similar functionality to from_html in the deserializer. Form encoded put and post request don't necessarily have to be from a browser, they could be from some client app that sends form encoded data.

Since Django already parses out the POST and FILES from the request on post, we might as well reuse those.

This seems to be an alternative solution that uses the deserializer, although I feel like the deserializer should not be dealing with requests. https://github.com/klipstein/django-tastypie/commit/9acd24b1acf425a26785df7690ba3c7c8d0483c5

Hydration should be handled automatically so that a ModelResource will only have files overwritten or created if a file is provided.

Hopefully this isn't too soon to post, I know you are actively working on this @toastdriven . The below passes in 9.11 but fails with the new commit SHA: c83698ac7fd5369acd8e5a52f3b5409a8f02b965

Some clients cause tastypie to return a 500 error because they send a request with an HTTP Accept header which contains an invalid MIME type (e.g. any value without a "/" other than "*", which mimeparse handles).

This patch simply causes tastypie to catch the ValueError and fail down to the default format

Starting in this commit obj_update calls full_hydrate twice. This means that if non-idempotent transformations happen in a user's hydrate() functions it will result in an attribute that isn't in the expected state.

As reported in #tastypie by @jpadilla, when sending a PUT to a resource with a ToManyField, the Django ORM aborts with the message int() argument must be a string or a number, not 'ManyRelatedManager'.

Reference resources are located in this gist: https://gist.github.com/5820c76971797bf799bc A traceback is located here: https://gist.github.com/ea1afa28caf4859b2f26 The kwargs that are causing the issue are here: https://gist.github.com/adee82c997a3f872e005

The problem was found when piping the result of a get_detail on the BookingResource into a put_detail.

I've added support for Generic Relations in the API by modifying the RelatedField to allow the to field to be a dictionary which maps django models to Resources. Basic usage is as follows:

Django Model:

class GenericTag(models.Model):
    name = models.CharField(max_length = 30)
    object_id = models.PositiveIntegerField()
    content_type = models.ForeignKey(generic.ContentType)
    content_object = generic.GenericForeignKey()

    def __unicode__(self):
        return u"%s" % (self.name)

Resource:

class GenericTagResource(ModelResource):
    content_type = fields.ContentTypeField()
    content_object = fields.ToOneField(
        {Category : CategoryResource, Taggable : TaggableResource}, attribute="content_object", contenttype_field=content_type)

    class Meta:
        resource_name = 'generictag'
        queryset = GenericTag.objects.all()
        authorization = Authorization()

The to field dictionary tells the RelatedField class what Resources to use when hydrating/dehydrating. A contenttype_field reference must also be passed if writing is allowed which allows for the proper type object to be written. Two new classes were added, ContentTypeField which provides a shortcut for this purpose and ContentTypeResource which users can subclass to customize. I've left it up to users to add ContentTypeResource to their urlconf by using Api.register or some other method. All functionality is supported including POST/PUT with nested resources. I've also written tests for the code in the GenericForeignKeyTest class inside tests/related_resource/tests.py The reverse GenericRelation is supported by using the ToManyField. All tests pass when run with tests/run_all_tests.sh

Imagine MyResource has a field whose attribute is using relations, and it returns id of the object on the far side of the relation, for example:

faraway_id = fields.IntegerField('foo__bar__baz__faraway_id')

Now imagine you want to be able to filter your objects on foo__bar__baz__faraway_id but you want the filter parameter to be named just faraway_id (to be consistent with what's being returned). To be more specific, you want the call to look like this:

GET /my-resource/?faraway_id=18

In 0.12 it worked without problem, just by overriding build_filters(filters) I could map the faraway_id to foo__bar__baz__faraway_id

In 0.14 however, if I try to do the same thing, the call to super().build_filters(filters) throws an error: The 'faraway_id' is not a valid field name. Apparently it tries to find a valid list of query lookups for foo__bar__baz__faraway_id and it fails, for obvious reason.

1. The message is super confusing to a programmer, one needs to read the library sources to figure out what is even going on.
2. The only workaround I can think of is to remove the faraway_id field from MyResource and add it manually in the dehydrate, which is rather ugly.

Does anybody else knows an easier, and human-friendly way of doing this?

When importing tastypie.api.Api, using Django v4.1, I get an error. It was OK with v4.0.6.

The end of the traceback looks like this:

Looks like it's this commit in Django, where django.middleware.csrf._sanitize_token was changed to django.middleware.csrf._check_token_format.

Using django-tastypie v0.14.4, python 3.8.

Previously in version 0.14.1 I could post a request to create a resource with a related resource id and it would work. Here's an example of interacting with a toy application (example here)

>>> h = {'content-type': 'application/json', 'accept': 'application/json'}
>>> d = {'name': 'some book', 'author': 1}
>>> r = requests.post('http://127.0.0.1:8000/api/v1/books/', data=json.dumps(d), headers=h)
>>> r.status_code
201

In the latest version of tastypie, it fails.

>>> d = {'name': 'another book', 'author': 1}
>>> r = requests.post('http://127.0.0.1:8000/api/v1/books/', data=json.dumps(d), headers=h)
>>> r.content
b'{"books": {"author": ["This field is required."]}}'
>>>

I believe this is due to the change from after 0.14.1 starting from where this was added in FormValidation form_args

            # iterate over the fields in the object and find those that are
            # related fields - FK, M2M, O2M, etc.  In those cases, we need
            # to *not* use the data in the bundle, since it is a URI to a
            # resource.  Instead, use the output of model_to_dict for
            # validation, since that is already properly hydrated.
            for field in bundle.obj._meta.fields:
                if field.name in bundle.data:
                    if not isinstance(field, RelatedField):
                        kwargs['data'][field.name] = bundle.data[field.name]

It's setting the value for the related resource (author in my example) to None because the bundle does not have that value.

I'm using tastypie 0.14.4

Tastypie app should have an apps.py module, with some reasonable configuration. At bare minimum it should look like this:

from django.apps import AppConfig

class TastyPieConfig(AppConfig):
    default_auto_field = "django.db.models.BigAutoField"
    name = "tastypie"

Without it, django 3.2 raises the following warning on startup:

WARNINGS:
tastypie.ApiAccess: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'.
	HINT: Configure the DEFAULT_AUTO_FIELD setting or the AppConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'.

Could you please consider to use built-in unittest.mock instead of mock, as a fallback at least?
