I'm using GeoIP for geo location with django and it works fine - locates city, country etc. But what i want is to locate the country name if is searched the city name. Example:
Search: Madrid
Found country: Spain
Search: Paris
Found country: France
Is this possible with GeoIP and if it is, how?
Thanks!
It's not possible. GeoIP can only map IP to country/city, that's all.
You should try experimental Google Places API - you can use it to check in which country eg. Madrid is.

I have two models with the same primary key:
class OperationalDevice(models.Model):
ip = models.GenericIPAddressField(primary_key=True)
mac = models.CharField()
class AllowedDevice(models.Model):
ip = models.OneToOneField(OperationalDevice, primary_key=True, on_delete=models.DO_NOTHING, db_constraint=False, db_column='ip')
type = models.CharField()
owner = models.CharField()
I would like to display the list of all AllowedDevices that are down - kind of like:
SELECT AllowedDevice.ip from AllowedDevice
LEFT OUTER JOIN OperationalDevice ON
AllowedDevice.ip = OperationalDevice.ip
WHERE OperationalDevice.ip is NULL
I tried using AllowedDevice.objects.filter(ip__...), but it creates inner join. I also tried objects.exclude and objects.annotate, and they also create a query with inner join
Maybe I should't be using OneToOneField?
Making the relationship go the other way is not a solution, because I need to find both kinds of exceptions - devices that are in one table but not the other.
This is related to my previous question:
I have two tables with the same primary key.
ip mac
11.11.11.11 48-C0-09-1F-9B-54
33.33.33.33 4E-10-A3-BC-B8-9D
44.44.44.44 CD-00-60-08-56-2A
55.55.55.55 23-CE-D3-B1-39-A6
ip type owner
22.22.22.22 laptop John Doe
33.33.33.33 server XYZ Department
44.44.44.44 VM Mary Smith
66.66.66.66 printer ZWV Department
The first table is automatically refreshed every minute. I can't
change the database structure or the script that populates it.
Both tables have ip as PRIMARY KEY.
In a view, I would like to display a table like this:
ip mac type owner Alert
11.11.11.11 48-C0-09-1F-9B-54 Unauthorized
55.55.55.55 23-CE-D3-B1-39-A6 Unauthorized
22.22.22.22 laptop John Doe Down
66.66.66.66 printer ZWV Department Down
33.33.33.33 4E-10-A3-BC-B8-9D server XYZ Department OK
44.44.44.44 CD-00-60-08-56-2A VM Mary Smith OK
How can I model this? Should I make one of the two primary keys a
foreign key into the other one?
Once the code is in operation, there will be lots of data, so I want
to make sure it's fast enough.
What is the fastest way to retrieve the data?
To use left outer join you should use .values('one_to_one_field__sub_filed') or .annotate(sub_field=F('one_to_one_field__sub_filed')):
from django.db.models import F
AllowedDevice.objects.all().annotate(mac=F('ip__mac'))
But I think that you really need a "FULL JOIN" that can only be simulated using QS.union(). See the last part (Using OneToOneField for better SQL) of answer to your original question for details.
We want to be able to query local sellers based on seller's preferred distance to a geolocation set by a customer using PostgreSQL and Django models.
Our seller model is given below:
class Seller(AbstractModel):
user = models.OneToOneField('users.User')
distance = models.IntegerField()
geoposition = GeopositionField()
For example:
Seller John can travel 50 miles. If buyer's location(lat, long) is 49 miles a John's geoposition, we get John.
Alternatively you can write a solutions with just postgreSQL.
Try filtering the query using a distance calculation between the buyer and seller location and compare that to the sellers preferred distance.
It appears you want a arithmetic query correct? I think the above example will help you ask me and the community with more questions.
First of all, Thank You. Here is my Boondoggle...
Currently, users are required to do regular training which is printed
and stored in user's manila folder.
My objective:
Create a SharePoint List page with InfoPath forms for each training item.
Included in this form:
Training Title/Description/Due date
User Name - Repeating table pulled from a data connection to a SharePoint list with "User Names".
(60 users max, this list also has title, name, phone number)
A PDF attachment for their certificate of completion.
EXAMPLE:
Blow your nose today.
Due Date 08-23-2013
Name Attachment

Bill Smith YYY.PDF

I am able to create the repeating table list of names from the 'user names' List.
But, I cannot figure out a way to attach a file to each name individually.
I add a file and it populates the entire list.

Any ideas would be greatly appreciated, Thank you in advance!
Selecting distinct(country) from my maxmind database i found country with code "AN", that is not in list here:
http://dev.maxmind.com/geoip/codes/iso3166
and on wiki:
http://en.wikipedia.org/wiki/ISO_3166-1
For which country it can refer to?
According to http://www.iso.org/iso/home/standards/country_codes/iso-3166-1_decoding_table.htm
This is Netherlands Antilles
Or, I'm fine downloading all the cities in a country, and searching in memory.
It's actually quite simple but not (obviously) documented... Just query http://graph.facebook.com/106078429431815 with 106078429431815 being the city id (London in this example).
