我如何循环通过对象的字段？

I have a model like this, how can I loop through it and not have to type out company.id, company.name, etc?

我有这样的模型，我如何循环它而不必输入company.id，company.name等？

class Company(models.Model):
    name = models.CharField(max_length=1000)
    website = models.CharField(max_length=1000)
    email = models.CharField(max_length=200)
    phone_number = models.CharField(max_length=100)
    city = models.CharField(max_length=1000)
    zip = models.IntegerField()
    state = models.CharField(max_length=1000)
    address = models.CharField(max_length=1000)
    address2 = models.CharField(max_length=1000)

4 个解决方案

#1

First get them, then use a for loop or list comprehension.

首先得到它们，然后使用for循环或列表理解。

#2

You can loop over all field names like so

您可以循环遍历所有字段名称

for name in Company._meta.get_all_field_names():
    print name

this also works if you have a category instance:

如果你有一个类别实例，这也有效：

c = Company(name="foo",website="bar",email="baz@qux.com",....,)
c.save()
for field in c._meta.get_all_field_names():
    print getattr(c, field, None)

Update for Django 1.8

Django 1.8的更新

Django 1.8 now has an official model Meta api and you can easily grab all the fields:

Django 1.8现在有一个官方模型Meta api，您可以轻松获取所有字段：

from django.contrib.auth.models import User
for field in User._meta.get_fields():
    print field

#3

Iteration in a view:

在视图中迭代：

If you have an instance company of Company:

如果您有公司的实例公司：

fields= company.__dict__
for field, value in fields.items():
    print field, value

#4

this is a possible solution:

这是一个可能的解决方案：

entity = Company.all().get()

for propname, prop in entity.properties().items():   
    print propname, prop.get_value_for_datastore(entity)

another one could be:

另一个可能是：

# this returns a dict with the property 
# name as key and the property val as its value
entity.__dict__.get('_entity')
