Mongoengine + Django-tables2：所需的表或查询集，而不是QuerySet

Question

I'm starting to learn django and using it to build and interface to our mongoDB using also mongoengine. I'm following this tutorial to use django-tables2 but I can't even start it because I get the error Expected table or queryset, not QuerySet . This is the class I'm using:

class Companies(Document):
    url = StringField(required=True, unique=True)
    name = StringField(required=True)
    founded = IntField()
    headquarters = EmbeddedDocumentField(HQ)
    description = StringField()

On the view I'm just doing

def companies(request):
    return render(request, 'toolbox/companies.html', {'companies': Companies.objects.all()})

I see that mongoengine output is a QuerySet type. How can I convert it to some type I can input on django-tables? Thank you for the help!

Answer 1

The data format django-tables2 expects is a QuerySet, a list of dicts, or something behaving like that. You can create a class inheriting from TableData , pass that to a vanilla django_tables2.Table and put that in your context instead of Companies.objects.all() .

It would look somewhat like this:

import django_tables2 as tables
from django_tables2.data import TableQuerysetData


class TableDocumentData(TableQuerysetData):
    # not sure what to override here, since I do not know the mongoengine API at all


def companies(request):
    table = CompanyTable(data=TableDocumentData(Companies.objects.all()))

    return render(request, 'toolbox/companies.html', {'companies': table})
