使用 Modelform 选择值以填充组合框
Selecting values to populate the combobox using Modelform
我想获取列表中的所有国家/地区名称,以便将其设置为下拉列表的来源。
我的模型class如下所示
class UserExtForm(ModelForm):
countries = Countries.objects.values('countryname').filter(countryname__isnull = False)
class Meta:
model = UserExtras
fields=['phone','aboutme','countries']
我试图用所有国家/地区名称填充国家/地区对象,但是当显示 html 表单时,下拉列表中填充了文本 'Countries object'。请帮助我指出这里的内容。
非常感谢
在你的models.py
from django.db import models
class Article(models.Model):
countries = models.CharField(max_length=200) //whatever
def __str__(self): # __unicode__ on Python 2
return self.countries
取自the docs :
"It’s important to add str() methods to your models, not only for your own convenience when dealing with the interactive prompt, but also because objects’ representations are used throughout Django’s automatically-generated admin."
