For a simple ModelSerializer, the response JSON contains instances of
models, which fails when the response is JSON serialized. For example:
class AccountSerializer(ModelSerializer):
tokens = SerializerMethodField()
def get_tokens(self, obj):
token_list = []
for token in obj.get_tokens():
token_list.append({
'client' : token.client, # <----- token.client is an
instance of a model
'account_id' : token.account_id
})
return token_list
The response fails with the following error:
TypeError: <client object> is not JSON serializable
This was perfectly valid in rest framework 2.x, as the result of the
get_tokens method would then be automatically serialized further.
I'm wondering, is there an easy way to upgrade for this type of expected
behavior to DRF v3, or can I simply not rely on code like this and
explicitly serialize objects? As an aside, I've noticed instances of models
in the result of ModelSerializer calls where the ModelSerializer was
serializing anything more than depth=1.
After extensive searching, I have not found another issue like this one and
so any help would be appreciated.
Thank you
