In this Django free course with certificate, we will be discussing all about building the Django delete data command.
The Django delete data command is a powerful tool that can be used to remove data from the database. It is one of the most popular commands in Django.
The command is used to remove data from a table and can be executed with options that specify what you want to delete. There are three different ways of executing the command - by using a single argument, by using multiple arguments, and by passing in an SQL query string.
The delete data command is an important part of the Django framework. It helps you to delete content from a model or a database table.
The command can be used in three ways:
1) To remove all the records associated with a given object:
E.g. - python manage.py dbshell # Delete all the records in this database table (this will be destructive)
2) To remove specific records from a given object:
E.g. - python manage.py dbshell # Delete all the records where "age" is greater than 23
3) To remove specific rows from a given table:
E.g. - python manage.py dbshell # Delete all rows where "name" is "John Doe"
Coming to the Django delete app command deletes all the data from a specific application. It is used to delete any database tables, models, views, and settings.
The main purpose of this command is to get rid of unused or old code. It can be used to remove old versions of an application that no longer need it or to remove old applications that are no longer needed in order to free up space on the server.
When you delete a database in Django, it is not deleted from the filesystem. Instead, it is removed from the database and marked for deletion.
The process of deleting a database in Django can be done by using the following commands:
delete_database() - Deletes the given database from your system.
drop_database() - Drops the given database from your system.
