Re: Raw SQL - How to approach paging and lazy fetching

Hi, Even you do have legacy database, you can use unmanaged models and then leverage full power of ORM [1]. Just create models and in their Meta set managed = False and there you go. And what comes to paging - you need to somehow pass offset and limit to your query. [1] https://docs.djang

I have done some digging into the QuerySet API, and I think I may have found what you are looking for: MyModel.objects.all().query.get_meta().fields You can access the fields that are deferred by using MyModel.objects.all().query.deferred_loading. Note that the deferred columns will still be r

Hi, Bruno Soares, well values_list is not what I'm looking for, I'm searching for a list of field names, not field values. Imagine you have a queryset you know nothing about it (how it gets generated) and you want to build a representation (table) of it. The first thing would be to render the

You may be looking for values. MyModel.objects.all().values() returns a QuerySet list of dictionaries with the field names as the keys. You can specify which specific fields you want to return by passing them as arguments to values(). MyModel.objects.all().values('id', 'name') Then you can use th
