django migrations git version-control Python

I'm maintaining legacy code that After trying multiple solutions online, I still can't figure this out. I'm currently working on a Django 4.2 project where multiple team members are working on separate branches, and we're experiencing issues with migration conflicts when merging. Recently, I attempted to merge a feature branch that added a new model and its migrations, but when I ran `python manage.py migrate`, I encountered the following behavior: ``` django.db.migrations.exceptions.ConflictingMigrationError: ("app_name", 0002): Conflicting migrations detected; multiple migrations with the same name ('0002_auto_20231001_1234') detected in 'app_name'. ``` To address this, I tried using `python manage.py makemigrations --merge`, hoping it would resolve the conflict. However, it simply created a new migration that doesn't seem to apply the changes made in both branches correctly. The new migration file includes this: ```python # -*- coding: utf-8 -*- # Generated by Django 4.2 on 2023-10-01 12:00 from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ('app_name', '0001_initial'), ('app_name', '0002_auto_20231001_1234'), ] operations = [ migrations.AddField( model_name='yourmodel', name='new_field', field=models.CharField(max_length=100, default=''), ), ] ``` This setup doesn't reflect the actual changes from both branches. I'm worried that the migration history might become messy and lead to further issues down the line. What strategies or best practices can I adopt to manage these migration conflicts more effectively? Is there a recommended way to consolidate or handle migrations across branches without losing data integrity or causing confusion? I'd really appreciate any guidance on this. I've been using Python for about a year now. Has anyone dealt with something similar?
