如何将数据转储 (SqLite3) 中的数据导入 django？

Question

I have a data dump file(.sql) containing certain data, I would like to import it to my database(currently Sqlite3 but thinking about changing to MySQL) in order to use it in my test website. Also, I need to know if it's possible to add the models too automatically, I presume it needs to be added manually, but any how, if there is any way to solve it, please suggest it.

Answer 1

There is a way to help you generate the Django models automatically given you have an existing database. However this is a shortcut. You may then fine tune your models and add them to your app as needed.

Structuring your models in apps might force you to use the Models db_table meta option.

If at some point you would like to switch databases (Sqlite3 -> MySQL) you can export (dump) your current data to json. Then you could import (load) the data to the new database (after creating the database tables withmigrate command). To do this you can use Django management commands:

• Dump data
• Load data

Answer 2

I was able to get an alternative answer after researching a bit. Since I'm having a PostgreSQL data dump file with a file extension '.sql', I was capable of running a single command that imported the whole data dump into my local database, which is PostgreSQL. I'm using PgAdmin4 as my database management system and I installed psql during the installation of PgAdmin4, I added the psql to the path of my command prompt, hence it was accessible. In order to import the data dump, I used the command provided below,

psql -U <username> -d <database_name> < <file.sql>

The '<' after database_name is necessary, so be sure to include it. Here is the username of the configured account, is the database to which the data dump should be added, , is the file containing the data dump.
