How to validate a field with uppercase with django serializers-CodePudding

I am programming an API and I have noticed the following error when debugging. The following code does not validate the Status field

class DocumentSalesforceSerializer(serializers.Serializer):
    AccountId = serializers.CharField(required=True)
    ContactId = serializers.CharField(required=True)
    Status = serializers.CharField(required=True)
    StartDate = serializers.CharField(required=True)
    EndDate = serializers.CharField(required=True, allow_blank=True)
    Subject = serializers.CharField(required=True)

    def validate_status(self, Status):
        if Status not in ("New", "In Progress", "On Hold", "Completed", "Closed", "Cannot Complete", "Canceled"):
            raise serializers.ValidationError("Invalid Status")
        return Status

But, when I change the word "Status" to "status" like this:

class DocumentSalesforceSerializer(serializers.Serializer):
    AccountId = serializers.CharField(required=True)
    ContactId = serializers.CharField(required=True)
    status = serializers.CharField(required=True)
    StartDate = serializers.CharField(required=True)
    EndDate = serializers.CharField(required=True, allow_blank=True)
    Subject = serializers.CharField(required=True)

    def validate_status(self, status):
        if status not in ("New", "In Progress", "On Hold", "Completed", "Closed", "Cannot Complete", "Canceled"):
            raise serializers.ValidationError("Invalid Status")
        return status

Everything is working perfectly fine. Can anyone tell me why is it working like that and how can I do to validate the "Status" uppercase field? Thanks

CodePudding user response：

It's because the name of the attribute inside your model. You should follow the same naming convention you followed in your model. You have two ways to solve your problem:

Go to your model, and change status to Status

Use this in your serializer:

Status = serializers.CharField(required=True, source='status')

The following code does not validate the Status field.

It expects that the validator is named validate_Status, so with an uppercase S as well:

class DocumentSalesforceSerializer(serializers.Serializer):
    AccountId = serializers.CharField(required=True)
    ContactId = serializers.CharField(required=True)
    Status = serializers.CharField(required=True)
    StartDate = serializers.CharField(required=True)
    EndDate = serializers.CharField(required=True, allow_blank=True)
    Subject = serializers.CharField(required=True)

    def validate_Status(self, Status):
        if Status not in ("New", "In Progress", "On Hold", "Completed", "Closed", "Cannot Complete", "Canceled"):
            raise serializers.ValidationError("Invalid Status")
        return Status
