Question

setting.py

from pathlib import Path

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent

#TEMPLATES_DIR = path.join(BASE_DIR, 'templates')    #it dosen't work
#STATICS_DIR = path.join(BASE_DIR, 'statics')             #it also dosen't work

Please consern on the top and 3rd top line where is the main difference from Djago2.7 version

In Djnago2.7 where imported os as below,

import os

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

and I used the below code for connecting templates and statics forlder

TEMPLATES_DIR =os.path.join(BASE_DIR,"templates")
STATICS_DIR =os.path.join(BASE_DIR,"statics")

But there is differece in form Djnago 3.1 from pathlib imported Path given below,

from pathlib import Path

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent

and the os techinques dosen't works as below

TEMPLATES_DIR =os.path.join(BASE_DIR,"templates")
STATICS_DIR =os.path.join(BASE_DIR,"statics")

How can I make connection with templates and statics folder, need help.

Note: I create templates and statics folders in main projects where already presented manage.py and db.sqlite3 file. below the screenshot of my projects direction,

Answer 1

If you look at the top of the settings.py file, you'll see BASE_DIR is using pathlib:

BASE_DIR = Path(__file__).resolve().parent.parent

Because of this, you no longer need os to join the paths, you can simply do:

STATICS_DIR = BASE_DIR / "statics"

This is new in 3.1 - you can read about it in the release notes here: https://docs.djangoproject.com/en/3.1/releases/3.1/
