Hi,
i want to have the same model-field 2x in the query result.
The model.py is:
class Measurand(models.Model):
"""
A Model for measurement data
"""
entry = models.ForeignKey(Entry)
avg_value = models.FloatField(help_text='the average measurement
value', db_index=True, blank=True, null=True)
def __unicode__(self):
return 'Measurand:' + str(self.avg_value)
My raw-sql looks like:
cursor = connection.cursor()
cursor.execute(""" SELECT speed.avg_value, dir.avg_value
FROM data_measurand AS speed LEFT JOIN
data_measurand AS dir
ON speed.entry_id=dir.entry_id;
""", locals() )
row = cursor.fetchall()
How can i do this with the django-orm?
