django mssql inspectdb all schema and tables

[gustavosooeiro]

Fellows,

I am trying to generate models from all the tables of a MSSQL SERVER 2017 legacy database with a django inspectdb. My problem is that it is been generated just the tables that has dbo prefix. Other tables on other schemas, like HumanResources.Department, are not been generated.

I already tryed to change the Default Schema for the user connected in the database, but no success.

I've seen a few posts that suggests to change the behavior of inspectdb, but I dont know if this is the best solution, or to get it done right.

Any ideas about how to change that and get all tables?

If you want to generate models for existing tables with inspectdb, you will need to change the ownership of the schema for the tables to a database user you use in addition to changing the default schema for the database user. You can use ALTER AUTHORIZATION statement to change the ownership of a schema to a database user like the following.

ALTER AUTHORIZATION ON SCHEMA::HumanResources TO dbuser

And the following is the models I generated from tables belong to HumanResources schema in AdventureWorks2016 database using inspectdb.

# This is an auto-generated Django model module.
# You'll have to do the following manually to clean this up:
#   * Rearrange models' order
#   * Make sure each model has one field with primary_key=True
#   * Make sure each ForeignKey has `on_delete` set to the desired behavior.
#   * Remove `managed = False` lines if you wish to allow Django to create, modify, and delete the table
# Feel free to rename the models, but don't rename db_table values or field names.
