我已经定义了一个User类，它(最终)继承自models.Model.我想获得为此模型定义的所有字段的列表.例如，phone_number = CharField(max_length=20).基本上，我想检索从Field类继承的任何内容.
我以为我可以利用inspect.getmembers(model)来检索这些字段，但是它返回的列表不包含这些字段中的任何字段.看起来Django已经掌握了这个类，并添加了它的所有神奇属性，并go 掉了实际定义的内容.所以...我怎么才能拿到这些田地呢？它们可能有检索它们的功能，用于它们自己的内部目的？
因为大多数答案都过时了，我会试着向你通报Django 2.2的最新情况. 此处帖子-您的应用程序(帖子、博客、store 等)
1) From model链接:https://docs.djangoproject.com/en/stable/ref/models/meta/
from posts.model import BlogPost
all_fields = BlogPost._meta.fields
#or
all_fields = BlogPost._meta.get_fields()
请注意:
all_fields=BlogPost._meta.get_fields()
Will also get some relationships, which, for ex: you can not display in a view.
As in my case:
Organisation._meta.fields
(<django.db.models.fields.AutoField: id>, <django.db.models.fields.DateField: created>...
和
Organisation._meta.get_fields()
(<ManyToOneRel: crm.activity>, <django.db.models.fields.AutoField: id>, <django.db.models.fields.DateField: created>...
2) From instance
from posts.model import BlogPost
bp = BlogPost()
all_fields = bp._meta.fields
3) From parent model个
Let's suppose that we have Post as the parent model 和 you want to see all the fields in a list, 和 have the parent fields to be read-only in Edit mode.
from django.contrib import admin
from posts.model import BlogPost
@admin.register(BlogPost)
class BlogPost(admin.ModelAdmin):
all_fields = [f.name for f in Organisation._meta.fields]
parent_fields = BlogPost.get_deferred_fields(BlogPost)
list_display = all_fields
read_only = parent_fields
