Re: capture client side location in Django

[Salima Begum]

Hi all,

I tried use https://docs.djangoproject.com/en/3.1/ref/contrib/gis/geoip2/
and This particular package requires
GeoLite2-Country.mmdb.gz
GeoLite2-City.mmdb.gz
These databases are not free. We are looking for an open source API or
package for our web application.

I appreciate if someone can share suitable pointers.

Thanks
~Salima

There's rarely a "best way", since use cases differ and people tend to 
have different preferences, but I personally use django-configurations:


https://github.com/jazzband/django-configurations

And then use an environment variable for my secret key which is set in 
the service file I use for starting my Django UWSGI application in 
production.


Using django-configurations has the added benefit that I can easily have 
different configurations in development and production and the secret 
key is more or less the only thing I don't keep in revision control (git).


Of course, not sure if that's the "best way", but it's one way at least :-)

Kind regards,

Re: Setting up models and postgres in django 3.1

[Patrick Carra]

Figured it out 3.1 is more strict about how it creates tables in postgres.  
The workaround I used was to put the tables into the various 
appname/models.py and then import them as needed when I need them.

Setting up models and postgres in django 3.1

[Patrick Carra]

So I have worked in django 2.2 where I have multiple apps that I use the 
same models.py file in for all of them (same meaning I make sure each one 
is exactly the same as the others not one single models.py).  When I do 
migrations I have no problem with anything.  When I started using django 
3.1 if I try to do the same it creates tables in the postgres database for  
each app.  For example I have  a table called Menu_Item it creates tables 
for home_Menu_Item, custOrders_Menu_Item, and menu_Menu_Item.  How to get 
them all to use the same postgres table Menu_Item.   Why is django 3 acting 
differently.  I'm not sure what changed but it isn't working out well for 
me.

You use Pillow:

Double query to retrieve a Paginator's page

[hldev]

Paginator.page() 
 
when called for the first time will trigger the evaluation of the cached 
property "count", which performs a COUNT query on the database. It will 
generally happen every time, since a new Paginator object is made for each 
new request.
The problem here is that the COUNT query costs almost the same as the main 
query which retrieves the page's items, so in effect it's doubling the 
needed query.
How can I avoid that duplication?

Re: Stuck with Calculated feild

[Frederic Salvetat]

Hi Eankomah,

You have several solution depending upon your need:

 

> Le mercredi 23 septembre 2020 07:24:05 UTC+2, eankomah a écrit :
> Hi all am stuck at getting total_price Calculated in my model
>  
> class inventory(models.Model):

>   ...
> Thanks

 

First *dr neyx de godlove* answer is the more elegant if you do not need a 
dedicated db field.

You just need to remove the 'get_' prefix  in get_total_price :

 

@property

def total_price(self):

total_price = self.unit_price * self.quantity

return total_price

 

(*@dr neyx de godlove*, thank I learned the use of property in django 
trying you solution)

 

Then if you really need a dedicated field, create it and override the save 
method in your model :

total_price = models.FloatField()

 

def save(self, *args, **kwargs):

#change total_price

# Transaction.save(update_fields['total_price'])

self.total_price = self.unit_price * self.quantity

super(Inventory, self).save(*args, **kwargs)

Best Regards

Re: Stuck with Calculated feild

[Frederic Salvetat]

Hi Eankomah,
You have several solutions depending upon your need:

*>Le mercredi 23 septembre 2020 07:24:05 UTC+2, eankomah a écrit :*
*>Hi all am stuck at getting total_price Calculated in my model*
*>*
*>class inventory(models.Model):*
*>def __str__(self):*
*>return self.name*
*>  ...*
*>total_price = models.FloatField(total=('unit_price' * 'quantity'))*
*>  ...*
*>Thanks*

First *dr neyx de godlove*'s answer is the more elegant if you do not need 
a dedicated db field.
You just need to remove the 'get_' prefix  in get_total_price :

@property
def total_price(self):
total_price = self.unit_price * self.quantity
return total_price

(*@dr neyx de godlove*, thank I learned the use of property in django 
trying you solution)

Then if you really need a dedicated field, create it and override the save 
method in your model :
total_price = models.FloatField()

def save(self, *args, **kwargs):
#change total_price
# Transaction.save(update_fields['total_price'])
self.total_price = self.unit_price * self.quantity
super(Inventory, self).save(*args, **kwargs)


Best Regards

Backend exception after upgrade.

[Kirill Maksimov]

Hello guys. I'm using Python3.8 and Django2.2. 

After upgrade to django 2.2, I'm getting weird exception which happens only 
on ecs sever:

*AttributeError partially initialized module 'django_redis.cache' has no 
attribute 'RedisCache' (most likely due to a circular import)*

Also had similar exceptions for mysql backend:

*AttributeError partially initialized module 
'django.db.backends.mysql.compiler' has no attribute 'SQLInsertCompiler' 
(most likely due to a circular import)*

I wonder why it could happen? Also if I build and run the same container 
locally it works fine. Big thanks for any help.

Look in your log files for details. That should give you a clue.

Re: capture client side location in Django

You can read the client's IP address with -

request.META['REMOTE_ADDR']  -- ( not sure how it handles proxies, etc )



Proxies should set the X-Forwarded-For header:

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-For

the value of which will then be used in the META dictionary.

Worth noticing that it's trivially possible for any client to set that 
header as well and there's no way to reliably get the actual IP address 
of the client simply because of how HTTP works.


Of course that's just a variation of "never trust the client" :-)
