After creating the UserManager and User models, if the migration fails with the following error: Migration admin.0001_initial is applied before its dependency core_user.0001_initial on database 'default'.

Please try running these commands: $ sudo su postgres $ psql postgres=# DROP DATABASE coredb; postgres=# CREATE DATABASE coredb; postgres=# ALTER ROLE core SET client_encoding TO 'utf8'; postgres=# ALTER ROLE core SET default_transaction_isolation TO 'read committed'; postgres=# ALTER ROLE core SET timezone TO 'UTC'; postgres=# ALTER DATABASE coredb OWNER TO core; postgres=# GRANT ALL PRIVILEGES ON DATABASE coredb TO core;

If you already ran the "makemigrations" for core_user, simply run python manage.py migrate For more details check out this thread by our reader remyluslosius.

REST_FRAMEWORK = {

Basically here, all results are limited to 15 per page but we can also increase this size with the limit parameter when making a request and also use the offset parameter to precisely where we want the result to start from: GET https://api.example.org/accounts/?limit=100&offset=400
