How to iterate a PlainLocationField object and fetch some values? - PrateekG - Jun-21-2018
Hi All,
I am doing one mistake in my code but unable to solve this.
from location_field.models.plain import PlainLocationField
class Store(OwnedModel):
address = models.TextField(default='Mumbai')
location = PlainLocationField(based_fields=['address'], zoom=7, null=True)
@property
def latitude(location):
if not location:
return
latitude = location[1]
return latitude
@property
def longitude(location):
if not location:
return
longitude = location[0]
return longitudeIssue in above code is PlainLocationField object does not support indexing.So I am unable to return latitude,longitude from location.
Can anyone please help me to solve this?

Return the location object to see what it is. It's type and so on.

location object is returning latitude and longitude in the following format:
1.3762866,103.86537729999998

Is it just string/csv data?
Split it by the comma and return the first object for the one location and in the other @property method the same with the second object for the other location.

If you see my code, I am using following django package to fetch the location-
django location widget
So it's just not string/csv data.

I am not familiar with the Django library.
Return the type of the 'location' object to know how to process it. Obviously, it is not a list or a tuple so you can't get the first or the second index.

So from the documentation,

So split it by the comma and so on...
See the prev. post

I did following and it's working now-
from location_field.models.plain import PlainLocationField
class Store(OwnedModel):
address = models.TextField(default='Mumbai')
location = PlainLocationField(based_fields=['address'], zoom=7, null=True)
@property
def latitude(self):
if not self.location:
return
latitude, _ = self.location.split(',')
return latitude
@property
def longitude(self):
if not self.location:
return
_, longitude = self.location.split(',')
return longitude
class Meta:
managed = False
db_table = 'store'
RE: How to iterate a PlainLocationField object and fetch some values? - wavic - Jun-21-2018
@property
def longitude(self):
if not self.location:
return
return self.location.split(',')[1]And thenclass_instance.longitude?
