python - 在用户表单 django 中设置默认值

Question

我需要在用户表单中添加一个额外的默认值，但不会向用户询问，默认情况下它会保存在每个用户的数据中，但我该怎么做？这是我的表格

from django import forms
from django.contrib.auth.models import User


class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput, min_length=6) 
    confirm_password = forms.CharField(widget=forms.PasswordInput(), min_length=6) 
    first_name = forms.CharField(max_length=30) 
    last_name = forms.CharField(max_length=30) 
    email = forms.EmailField(max_length=254) 

Answer 1

我想我明白你在问什么。如果您要使用 ModelForm，您应该在此处了解类元:如何适用于 ModelForm这应该可以帮助您开始在表单中添加一个附加字段。如果您要向用户模型添加一些额外的数据，您将需要使用 AbstractUser 扩展用户模型。并添加“additional_field”。

from django import forms
from django.contrib.auth.models import User


class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput, min_length=6)
    confirm_password = forms.CharField(widget=forms.PasswordInput(), min_length=6)
    first_name = forms.CharField(max_length=30)
    last_name = forms.CharField(max_length=30)
    email = forms.EmailField(max_length=254)
    additional_field = forms.CharField(max_length=100)

    def __init__(self, *args, **kwargs):
        super(UserForm, self).__init__(*args, **kwargs)
        self.fields['additional_field'].disabled = True
        self.fields['additional_field'].initial = 'SOME INITIAL VALUE'
