django 通过模型获取惰性引用

Question

要从延迟引用中获取模型，我们可以这样做

from django.apps import apps
Article = apps.get_model('articles.Article') 
# app.Model

但是反过来呢？我的意思是通过 Model class.

获得惰性引用 app.Model

from articles.models import Article
# something like
print(Article.lazy_reference)
# <str> articles.Article

you probably wonder why I do this, I need to tract user initiative and passive actions, there's no modelfield in django, hence I store the model reference and pk as indication.

Answer 1

使用meta选项，

model_meta = Article._meta

lazy_ref = f"{model_meta.object_name}.{model_meta.app_label}"

django 通过模型获取惰性引用

django get lazy reference by Model

django

django-models
