When i hit insomnia with this request bellow then it shows this response. How can i solve this issue?
Request:
query{
datewiseCoronaCasesList{
updatedAt,
affected,
death,
recovered
}
}
Response:
{
"errors": [
{
"message": "Received incompatible instance \"{'updated_at': datetime.date(2020, 4, 8), 'affected': 137, 'death': 42, 'recovered': 104}\"."
}
],
"data": {
"datewiseCoronaCasesList": [
null
]
}
}
My expectation which i have already gotten in errors message but this way:
{
'updated_at': datetime.date(2020, 4, 8),
'affected': 137,
'death': 42,
'recovered': 104
}
My GraphQL query:
class CoronaQuery(graphene.ObjectType):
datewise_corona_cases_list = graphene.Field(CoronaCaseType)
def resolve_datewise_corona_cases_list(self, info, **kwargs):
return CoronaCase.objects.values('updated_at').annotate(
affected=Sum('affected'),death=Sum('death'), recovered=Sum('recovered'))
My model:
class CoronaCase(models.Model):
affected = models.IntegerField(default=0)
death = models.IntegerField(default=0)
recovered = models.IntegerField(default=0)
district = models.CharField(max_length=265, null=False, blank=False)
created_at = models.DateTimeField(default=timezone.now)
updated_at = models.DateTimeField(default=timezone.now)
def __str__(self):
return "Affected from: {}".format(self.district)
Under CoronaQuery
class, since you are returning a list of objects (instances), graphene.Field
should be changed to graphene.List
.
I mean:
class CoronaQuery(graphene.ObjectType):
datewise_corona_cases_list = graphene.List(CoronaCaseType)
