[英]Adding a value to a queryset in Django
In my Django form I have a ModelChoiceField for employees, but I want a choice in the dropdown for 'all' employees. 在我的Django表单中,我有一个供员工使用的ModelChoiceField,但我想在下拉菜单中为“所有”员工选择。 What would be the best way to accomplish this? 做到这一点的最佳方法是什么?
employees = forms.ModelChoiceField(queryset=Employees.objects.all())
First attemptI tried 第一次尝试
employees = forms.ChoiceField(choices = Employees.objects.values())
but I get a 'too many objects to unpack' error 但出现“无法解包的对象太多”错误
Thanks 谢谢
Try this: 尝试这个:
employees = forms.ChoiceField(choices = [(emp['id'], emp['full_name'])
for emp in Employees.objects.values('id', 'full_name')])
The too many objects to unpack error raised because every cell of chioces must only contains two value similar below: 出现太多无法解包的对象的错误,因为每个chioceo单元格只能包含两个类似以下的值:
[(1, 'Eric Manson'), (2, 'Julia Rose'), (3, 'Saadi Khorshid'), ...]
But Employees.objects.values()
unpacking all fields in dictionary form. 但是Employees.objects.values()
以字典形式解压缩所有字段。
