Problem with rest_framework.authtoken

[wylswz]

One line description of the issue

I was migrating my django project from MySQL to mongodb. When I apply the migration, this issue occurs. It seems like it's not working well with restframework.

Hi this looks like a genuine djongo issue. Django connector expects several interfaces to be implemented and not all up yet! these will be implemented at some time.

[ravinarayansingh]

@nesdis any suggestion how can we resolve this issue and please explain to me, I will work on this issue and contribute to this project. My problem is i want to write unit tests for our DRF API. But Django will create database so we are getting

NotImplementedError: subclasses of BaseDatabaseIntrospection may require a get_constraints() method

I am stuck :(

[nesdis]

In file introspection.py in djongo, you must implement the get_constraints function. The function takes in the collection name and returns a dict of properties.

You need to use pymongo commands to get the constraints for different fields.

Some constraints like primary key, have no meaning in mongoDB, You need to store the primary key field name in schema , and return this in this function.

Indexing support needs to be added to djongo, you can then return indexed fields.

Returns a dict mapping constraint names to their attributes, where attributes is a dict with keys:

• columns: List of columns this covers
• primary_key: True if primary key, False otherwise
• unique: True if this is a unique constraint, False otherwise
• foreign_key: (table, column) of target, or None
• check: True if check constraint, False otherwise
• index: True if index, False otherwise.
• orders: The order (ASC/DESC) defined for the columns of indexes
• type: The type of the index (btree, hash, etc.)

Please, could you provide me some more detailed solution? Thank you!

Get constraints has been implemented, you may want to clone the latest version and check if it works for your project

[ayakut]

Hi guys,

Thank you for the update!

The "pip install djongo==" shows me the last version is 1.2.9 Collecting djongo== Could not find a version that satisfies the requirement djongo== (from versions: 1.1, 1.2, 1.2.2, 1.2.3, 1.2.4, 1.2.5, 1.2.6, 1.2.7, 1.2.8, 1.2.9) No matching distribution found for djongo==

Should we ignore the "pip install" and try to work via cloning of the project?

Thank you!

[nesdis]

Yes clone the project..
