从Django迁移中排除应用程序

Question

有没有办法从Django迁移中排除应用程序的模型？我知道用managed = False更改模型元选项是一个选项，但每次都要编辑很多模型。有没有办法指定我不想迁移其模型的应用程序？

Answer 1

从apps migrations目录中删除__init__.py文件应该有效。

Answer 2

从您设置中的已安装应用中删除该应用。

Answer 3

如果您将数据库路由器与

    def allow_migrate(self, db, app_label, model_name=None, **hints):
        return False

示例。

class FilemakerRouter:
    """
    A router to control all database operations on models in the
    filemaker application.
    """
    def db_for_read(self, model, **hints):
        """
        Attempts to read filemaker models go to filemaker.
        """
        if model._meta.app_label == 'filemaker':
            return 'filemaker'
        return None

    def db_for_write(self, model, **hints):
        """
        Attempts to write filemaker models go to filemaker.
        """
        if model._meta.app_label == 'filemaker':
            return 'filemaker'
        return None

    def allow_relation(self, obj1, obj2, **hints):
        """
        Allow relations if a model in the filemaker app is involved.
        """
        if obj1._meta.app_label == 'filemaker' or \
           obj2._meta.app_label == 'filemaker':
           return True
        return None

    def allow_migrate(self, db, app_label, model_name=None, **hints):
        return False
