重构：如何删除模型？
我有一个导致过多复杂性的模型，因此我想消除它，转向一种更简单的做事方式。不过，我不想立即将数据删除在此数据库表中。
class PRSblock( models.Model):
PRS = models.ForeignKey( 'jobs.PRS2', models.CASCADE, related_name='prs_blocks')
# no other relational fields
因此，首先，将相关名称prs_blocks迁移到opstolete_prs_blocks，然后在prs模型中，添加@property prs_blocks将surstert从未被调用过（要捕获我未能删除的任何代码的任何位），
其次，重命名模型prsblock obsolete_prsblock。 IIRC Django Makemigrations会询问我是否重命名，如果我说是的，它将保留数据库表。
这听起来很明智，还是我没有遇到过？
I have a model which is causing too much complexity, and so I want to do away with it and move to a simpler way of doing things. I don't immediately want to scrap the data in this database table, though.
class PRSblock( models.Model):
PRS = models.ForeignKey( 'jobs.PRS2', models.CASCADE, related_name='prs_blocks')
# no other relational fields
So, first, migrate the related name prs_blocks to obsolete_prs_blocks and then in the PRS model, add a @property prs_blocks that will assert that it is never called (to trap any bits of code which I failed to remove)
Second, rename the model PRSblock to obsolete_PRSblock. IIRC Django makemigrations will ask whether I renamed it, and if I say yes, it will preserve the database table.
Does this sound sensible or are there any gotchas I haven't though of?
