使用现有的sqlite3数据库和Django

Question

I am getting started with Django and have this particular question regarding using my own SQLite database with Django. What I mean is that if I create a new database and populate it everything works fine. Here is my situation now.

I have an existing database in my instance retail_data.sqlite3 in the BASE_DIR. I now want to use this as the data so I go ahed and add this to seettings as follows.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    },

    'retail_data':{
        'ENGINE':'django.db.backends.sqlite3',
        'NAME':os.path.join(BASE_DIR,'retail_data.sqlite3')

    }
}

The above piece of code is replicated from this site . I then use the inspectdb command (python manage.py inspectdb --database=retail_data > salesapp/models.py) to generate the models.py which can use my current database. Also I go ahead and update the admin.py file so that I can see it from my admin panel. In the admin panel however even though the data table is visible I am unable to view the data.

I was in doubt as to if the database actually consisted data so I used simple pandas.read_sql_query to query the data base and it has all the required data. How should I proceed? Your guidance is much needed. Thanks in advance

You will also need to tell Django which models use the database you've named 'default' , and which models use the database 'retail_data' .

You do this by writing a database router class .
