serialization without a view?

[cltrudeau]

Please describe what you are trying to achieve

I have some places in my code where I need to get at a JSON version of an object that aren't within the API. Is there some way to take advantage of the Schemas I've defined to convert?

Please include code examples (like models code, schemes code, view function) to help understand the issue

from ninja.hope_this_exists import serialization_helper 

class Job(models.Model):
   ...

class JobOut(Schema):
  ...

job = Job.objects.get(id=1)
serialized = serialization_helper(JobOut, job)

Hi @cltrudeau

Use .from_orm + .dict or .json methods:

job = Job.objects.get(id=1)
data = JobOut.from_orm(job)

data.dict()  # will return python dict (that can be converted to json)
data.json()  # will return string (with json)

Perfect thanks.

I notice the .from_orm method doesn't appear to be mentioned in the docs. Happy to make an MR. Maybe something in the "Response Schema" section?

@cltrudeau sure - go ahead

@vitalik how does from_orm works with queryset? I have been qurious since I l faced #495 issue.

@quroom

qs = Job.objects.all()[:100]

result = [JobOut.from_orm(i).dict() for i in qs]

Docs got added. As it was only documentation I was lazy and didn't build anything. Hopefully I didn't break anything :)

Hi @cltrudeau,

If your issue was resolved would you mind closing down this issue? ( its hard to get actual bugs in a pile of issues )
