I have two models

class Weather(model.model):

        region = models.ForeignKey(Region)
        district = models.ForeignKey(District)
        temp_max = models.IntegerField(blank=True, null=True, verbose_name='Max temperature (C)')
        temp_min = models.IntegerField(blank=True, null=True, verbose_name='Min temperature (C)')

and

class Plan(model.model):
    name = tinymce_models.HTMLField(blank=True, null=True)
    region = models.ForeignKey(Region)
    district = models.ForeignKey(District)

Provided for every region and district have unique row. I want to combine the result so that i can get all the columns of both tables

These two Models are not related to each other. ' I need to make the join like

join weather w on w.region = A.region and w.distric = A.district

so that result contains all the columns in everyobject like

obj.temp_max etc
