Problem to fill up the database

[edipretoro]

Hi,

I wanted to test cobweb as it could be useful for a research project I'm working on (the research project is named PROMISE, and its goal is to set up a strategic plan to archive belgian web; you can find more information about this project at https://www.kbr.be/en/promise-project).

Unfortunately, and if I was able to install cobweb with docker, I wasn't able to fill up the database. Here is the output when I run the following command docker-compose run web python3 manage.py loaddata toy_data.json:

Starting cobweb-django_solr_1 ... Done
Starting cobweb-django_db_1   ... Done

LINE 1: UPDATE "core_user" SET "password" = 'pbkdf2_sha256$100000$yj...
               ^


The above exception was the direct cause of the following exception:

I'm not familiar with Django, but I guess this mean the core_user table doesn't exist. Did I miss something trivial? I've checked with docker-compose ps if the db server was up and it is as you can see with the following output:

           Name                         Command               State            Ports

Thanks in advance for your help!
