Training Django ChatterBot

Hi, since the command (with the new version of ChatterBot) python3 manage.py train is no more supported, how can I train my online bot implemented with Django? I read that I have to create a new python file train.py, but I tried and I didn’t solve the problem.

This is part of my settings.py file:

CHATTERBOT = {
    'name': 'My Online Bot',
    'django_app_name': 'django_chatterbot',
	
    'storage_adapter' : 'chatterbot.storage.SQLStorageAdapter',
    'database_uri' : 'sqlite:///online_bot_database.sqlite3',

    'logic_adapters' : [
          {
		'import_path': 'chatterbot.logic.BestMatch',
		'statement_comparison_function': 'chatterbot.comparisons.levenshtein_distance',
		'response_selection_method': get_first_response
	  },
    ]
} 

How to properly set up the train.py file for this bot?

Thanks in advance,

Alan

For me, using the SQLStorageAdapter was not good enough because then the data would not show up in Django admin, but using a separate train.py with the chatterbot.storage.DjangoStorageAdapter that the chatterbot.ext.django_chatterbot app uses resulted in a django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet. error.

I did get it working by creating a custom manage.py command in my own Django application using the folder structure described in https://docs.djangoproject.com/en/3.2/howto/custom-management-commands/

and with the following management/commands/train.py

from django.core.management.base import BaseCommand, CommandError

from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer

class Command(BaseCommand):
    help = 'Train the chatbot with a corpus'

    def handle(self, *args, **options):
        chatbot = ChatBot(
            'ChatBot name from settings.py CHATTERBOT',
            storage_adapter='chatterbot.storage.DjangoStorageAdapter',
        )

        trainer = ChatterBotCorpusTrainer(chatbot)
        trainer.train(
            "chatterbot.corpus.english"
        )

        self.stdout.write(self.style.SUCCESS('Successfully trained!'))

Edit: and then finally you can use python3 manage.py train again 😃
