I am using Geomanager for storing MultiPolygon data.
I have below tables:
il
class Customer(gismodels.Model):
is_active = models.CharField(max_length=15, default="Inactive",
choices= ACTIVE_CHOICES)
name = models.CharField(max_length=255)
organisation_name = models.CharField(max_length=100, blank = True)
rating =
models.CharField(max_length=25,choices=RATING_CHOICES,null=True, blank=True)
description = models.TextField(max_length=255, blank=True)
email_primary = models.EmailField(max_length=1000 ,null=False,
default="test...@gmail.com")
email_secondary = models.EmailField(max_length=1000 ,null=True,
blank=True)
phone_primary = models.CharField(max_length=1000)
phone_secondary = models.CharField(max_length=1000, null=True,
blank=True)
address = models.CharField(max_length=2000, blank=True)
has_shop = models.CharField(max_length=128, verbose_name="Does he have
a shop?", choices=[('Yes', 'Yes'),('No', 'No')],blank=True)
working_hours_start =
models.CharField(max_length=12,blank=True,verbose_name="What is the
website = models.URLField(blank=True, null=True)
expertise = models.CharField(max_length=2000, blank=True)
experience = models.CharField(max_length=12, null=True, blank=True)
city = models.ForeignKey(City, null=True)
country =
models.CharField(max_length=255,choices=COUNTRY_CHOICES,null=True,
blank=True)
multi_poly = gismodels.MultiPolygonField(srid=4326, null=True,
blank=True,verbose_name="Service Locations")
objects = gismodels.GeoManager()
class Meta:
db_table = 'customer'
verbose_name = 'Customer'
verbose_name_plural = 'Customers'
class Logs(models.Model)
'''logs Info'''
merchant = models.ForeignKey(Merchant, verbose_name='Merchant')
message = models.TextField(max_length=255, blank=True)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
So from shell when i try to access merchant from logs object i get error
