Set null value for floatfield

[Rakhee Menon]

Hi,

Please could anyone tell how to set null value for FloatField and when I try with null=True and blank=true I get this error

AssertionError: Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'NoneType'>`

Regards,

You're not returning a response from the view method.  this has nothing to do with setting the value on the model field.

Yeah! but now I get this error

'required': 'This field is required.', 'null': 'This field may not be null.', 'invalid': 'Invalid data. Expected a dictionary, but got {datatype}.'}

ipdb> serializer.errors

{'cast_weight': ['A valid number is required.']}

In models.py 

cast_weight = models.FloatField(null=True, blank=True)

sounds like you didn't make a migration after the change.
