Django doesn't call model clean method

Question

I have a view, which creates models from CSV file. I\'ve added clean method to the model class definition, but it isn\'t called when model is created.

Here is exampl

Answer 1

I've found a solution to override method:

class CommonMeasurement(models.Model):
    timestamp = models.DateTimeField()
    value = models.FloatField()
    run = models.ForeignKey(Run)

    objects = models.Manager()
    analyzes = managers.MeasureStatManager()

    def save(self, **kwargs):
        self.clean()
        return super(CommonMeasurement, self).save(**kwargs)

    def clean(self):
        super(CommonMeasurement, self).clean()
        print 'here we go'
        if self.timestamp < self.run.timestamp_start or self.timestamp > self.run.timestamp_end:
            raise django_excetions.ValidationError('Measurement is outside the run')

But I'm not sure that it can be a good decision.
