# operation\models.py
from datetime import datetime
from django.db import models
from course.models import Course
from users.models import UserProfile

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'users',
'course',
'organization',
'operation',
]3、遷移到資料庫
makemigrations
migrate4、將四個App放到一起
- 新建package：apps
- 把四個App都拖進去
紅框內的 √ 記得去掉 - 然後Mark為sourceRoot
5、然而我們發現，在cmd下執行的話還是會報錯
需要在settings設定：
import os
import sys
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))再執行就可以了
未完待續~~~
