No ID replace when returning list of objects

[shlomiLan]

When I run this:

instance = self.api_class.objects.get_or_404(id=object_id)
return instance.to_json()

I get a single document with the ID field formated correctly:

{"amount": 1, "descreption": "BBB", "pay_method": "5b51fed52c88845720509757", "id": "5b5101de2c88845fdf1429ed"}

But when I do:

return self.api_class.objects.to_json()

I get the following list without the IDs been formatted:

[{"_id": {"$oid": "5b5101de2c88845fdf1429ed"}, "amount": 1, "descreption": "BBB", "pay_method": {"$oid": "5b51fed52c88845720509757"}}, {"_id": {"$oid": "5b5204772c88845720509759"}, "amount": 100, "descreption": "BBB", "pay_method": {"$oid": "5b51fed52c88845720509757"}}]

Am I doing anything wrong?

Well, simple encode/decode is already tested by test code (Check queryset integration test), but I think this issue might happens when you code a complex code.

Did you inherit/override something other than mongoengine_goodjson.document.Document?

I don't understand your solution.
My class is quite simple but I also used this package.
Now I have solved it by implementing the to_json method by myself in a class and then all my document Inheriting from it.

Hi,
As far as I read the code of that, flask_mongoengine seems to have their own Document class and QuerySet class that don't inherit mongoengine_goodjson.Document and mongoengine_goodjson.QuerySet. As the solution, you will need to create your own classes that inherit the both of mongoengine_goodjson classes and flask_mongoengine classes.

That solved my problem, but I had to set my class as follows:

class Expense(db.Document, gj.Document)

the other way (class Expense(gj.Document, db.Document)), didn't work
