Django 的 sqlmigrate 命令 在本文中，我们将介绍 Django 中的 sqlmigrate 命令。Django 是一个流行的 Python Web 开发框架，提供了丰富的功能和工具，用于简化开发过程。其中一个重要的功能是数据库迁移，能够帮助开发者管理数据库模式的变化。 To preview the SQL that Django will run to create the blog_post table in the database, you use the sqlmigrate command: python manage. reduces_to_sql = False # If this is False, Django will refuse to reverse past this operation. Django will write out the value as an instantiation of your class with the given arguments, similar to the way it writes out references to Django fields. Also if it needs any extra fields, they should be added in operations after SeparateDatabaseAndState. To prevent a new migration from being created each time makemigrations is run, you should also add a __eq__() method to the decorated class. reversible You can check the existing table name through sqlmigrate or dbshell. filter all migrations that have been applied. This requires an active database connection, which it will use to resolve constraint names; this means you must generate the SQL against a copy of the database you wish to later apply it on. Your new through model should use the same names for the ForeignKey s as Django did. Note that sqlmigrate doesn’t colorize its output.
