Graphene Django - Mutation with one to many relation foreign key
1
I would like to know how to properly create mutation for creating this django model:
class Company(models.Model):
class Meta:
db_table = 'companies'
app_label = 'core'
default_permissions = ()
name = models.CharField(unique=True, max_length=50, null=False)
email = models.EmailField(unique=True, null=False)
phone_number = models.CharField(max_length=13, null=True)
address = models.TextField(max_length=100, null=False)
crn = models.CharField(max_length=20, null=False)
tax = models.CharField(max_length=20, null=False)
parent = models.ForeignKey('self', null=True, on_delete=models.CASCADE)
currency = models.ForeignKey(Currency, null=False, on_delete=models.CASCADE)
country = models.ForeignKey(Country, null=False, on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
As you see, there are three Foreign keys. For model Currency, Country and Parent(self). Company DjangoObjectType looks very simple like this:
class CompanyType(DjangoObjectType):
class Meta:
model = Company
And finally my mutation class CreateCompany have Currency, Country and Self(Parent) defined like graphene.Field():
class CompanyInput(graphene.InputObjectType):
name = graphene.String(required=True)
email = graphene.String(required=True)
address = graphene.String(required=True)
crn = graphene.String(required=True)
tax = graphene.String(required=True)
currency = graphene.Field(CurrencyType)
country = graphene.Field(CountryType)
parent = graphene.Field(CompanyType)
phone_number = graphene.String()
class CreateCompany(graphene.Mutation):
company = graphene.Field(CompanyType)
class Arguments:
company_data = CompanyInput(required=True)
@staticmethod
def mutate(root, info, company_data):
company = Company.objects.create(**company_data)
return CreateCompany(company=company)
When i want to start django server, Assertion error will be raised.
AssertionError: CompanyInput.currency field type must be Input Type but got: CurrencyType.
I was finding some good tutorial for one to many foreign key for a long time, so if someone know how to implement this solution nice and clear I would be very glad.
PS: Please can you also show me example of GraphQL query, so I would know how to call that mutation? Thank you very much.

@KeykoYume Yes. To graphene.Field goes InputType not Type object. As you see class CompanyInput. All you need to do is change for example graphene.Field(CurrencyType) to graphene.Field(CurrencyInput). The same class for currency like CompanyInput for company.

Could you please write up the answer along with what you defined forCurrencyInputand the associated graphql query? I am having trouble with a create mutation because of a foreign-key field, I've tried implementing your above approach but obviously, I am short of something important.
