How to use the MigrationAutodetector manually for dynamic models

Hi All, I'm working on an API-server project that uses dynamically generated Django models, so it can service many user-provided datasets. To ease maintenance work, we'd like to generate the SQL statements to migrate database tables to a newer version of the schema. I've managed to use the

Problem, as you see is that Django is build for static models. So if you have a dynamic model, how would you construct (efficient) queries in your other views unless you know the structure of the data? Well you kind of can't since there is no structure. Also, what purpose would such a models

Re: Dynamic Models

Re: Dynamic Models

Hi, You're probably after EAV pattern (or anti-pattern depending who you ask). Implementing that in Django is relatively trivial, though with any kind of dynamics you'll going to loose most of the ORM goodies. This kind of leads to question that is Django ORM really needed for you at all?

I think you just need to define a generic model. I dont see how what you are asking is feasible since it would require that (on the fly that migrations are made). You can write a generic model where the types can be represented by a field name. On Thursday, 5 January 2017 17:33:07 UTC+2,

Hi Matthias , Thank you, I went for option 1 and it works perfectly! Funny, the add_to_class function basically does "setattr(cls, name, value)". So I had the right solution, only you have to do this after class creation, not inside its __init__ function. Good to know, will blog about this :)
