You can use also GraphQL instead of building REST APIs , it depends on your needs

You could install django-notifications-hq. Then, you could extend it including serializers and views for your api.

Why? That's painfull

Django ORM do magic for us

Andrej

Hello all, can I use my own Mysql queries instead of creating django models?

I was also very skeptical of all ORM's until I took time to try the Django ORM. I was even able to make a join over multiple tables on indexed keys and improve the query execution time from 10 sec to under 50 ms on tables with 10+ million rows. Now, I'm loving it. It is worth to learn it. You can even write custom SQL queries if you want to.

Jamil

What is the difference between authentication and permissions classes, I cannot find an adequate explanation from stack

Andrej

In authentication you find out if the credentials are right and which user it is. In permissions you check which rights the authenticated user has to see, change or delete a resource.

Jamil

In authentication you find out if the credentials are right and which user it is. In permissions you check which rights the authenticated user has to see, change or delete a resource.

So authentication allows you to map the request to the token(for token auth) to find the user, and then so that you can use the user within the permissions right

Jamil

without authentication we couldnt have permissions right?

Jamil

In authentication you find out if the credentials are right and which user it is. In permissions you check which rights the authenticated user has to see, change or delete a resource.

thanks

I am creating a django blog post. I want see the content which is specifically uploded by the user who is now logged in. But i am seeing all the post uploded by all user. How to see only post uploded by the user logged in.

I am using django.contrib.auth for user sign in via admin panel

you need to put conditions for that i guess

Vinayak Kumar

I can't think of {% if user.username == ? %}

nah....if the user is authenticated

Filter by user on the view

First obtain the user from the request and then filter it

Can use pythonanywhere or heroku

Yeah I totally agree with you for this stuff , I highly recommend pythonanywhere

Hi guys, what is the solution if I need to compare big text fields ( about 2k symbols)?

Roman

I have about 8M rows of data and I have a field text which has from 50 to 2k symbols, and this fields should be unique, but the comparison take too long, what is the way to avoid it ? use hash ?

Roman

The thing is that this super big field should be inique

Intrepid

Which os is good for python project?

Intrepid

And IDE?

Muflone

the os is irrelevant good IDEs are pycharm and vscode

2k symbol count is convenient for unique indexing on most of RDBMS solutions. If you can, you should check it in SQL level. Unless you can test data whether unique in SQL level, python set data structure behaves like hashmap, and it creates hash binary tree in background. If there are multiple hits to same hash(Yes this is possible) it tests out from a sub array.

2k symbol on unique =True on 8M

Django Docs is a great place to start: https://docs.djangoproject.com/en/3.1/topics/db/queries/

Mehmet

If you have possibility to implement in Java lang you can get much more performance thanks to its sub hash testing algorithm. You may use multiprocessing in python and map data to multiple cores for testing. Secondary Hashing is probably wont give performance enhancement in pure language because it is already stored as integer hashed. You can also search on red black tree algorithm to enhance insert performance

So in the sql level it does not compare to text== text but creates a hashed integer and compare those?

Mehmet

In sql level it leverages multiprocessing, hashing automatically. You should try to enhance performance first by fine adjustments on unique indexing, partitioning based on a field.

Roman

Okay, thanks

Mehmet

If you have authorization to tweak on RDBMS system parameters such as caching, purging behaviors memory parameters, you should try on that. Because mostly Databases do better performance tweaking on data than your implementation.

Roman

Ha, yeah I think so

Mehmet

Ha, yeah I think so

For example, partitioning table on multiple disks based on custom hashed(md5, sha256) field would be good first try to enhance insert performance. If you have this much insertion, you can research on async database shrinking(Example: vacuum analyze on Postgresql) with cronjobs. It leverages good calculation times while accessing and manipulation of data.
