Any other details that can be helpful
It seems that the new version of Django has changed the field parameter settings, resulting in the field not being found. Please help to check.

migrate command works well with Django 5.0.8 version. Only get error when upgrade to 5.1 version.

Hi @wilson-jw, the team still working on 5.1 support. Will let you know when that is ready.

@MichaelSun90 Hello sir, any news about the 5.1 support ?
It's already been 2 months since the end of mainstream support for 5.0.x
Thank you for you answer

Hello @MichaelSun90
Any estimated release date for mssql-django with Django 5.1 support? We are migrating our application from Django 3.2 to Django 5, and would like to use Django 5.1 instead of 5.0, as that's the latest version (we would ideally want to upgrade to Django 5.2 as soon as that's released as well).
