Djongo - how to add custom migration using raw mongodb command
I have a legacy mongodb database. And I create a django application witch uses it. Djongo is used as a database provider. I want to add a custom update in my migration file:
db.collection1.updateMany({}, [{$set:{"field2": "$field1.id"}}])
I trid to add this command to migration file but it leads to an error:
operations = [
migrations.RunSQL("""
update collection1
set field2 = "$field1._id"
"""),
]
What is the correct way to add this command to migration?
