我想要一个预先填写的表单,其中包含有关已登录用户的个人资料的详细信息(例如名字和姓氏),以便他们可以对其进行更新。我有一个带有名字和姓氏的自定义用户模型,然后有一个链接到该用户模型并对其进行扩展的配置文件模型,其中包含一些额外的信息。
我已经在个人资料模型中定义了一个常量,理论上该常量应该获得用户的名字和姓氏。
models.py:
class User(AbstractBaseUser):
email = models.EmailField(verbose_name="email", unique=True, max_length=255)
first_name = models.CharField(max_length=30, blank=True, null=True)
surname = models.CharField(max_length=30, blank=True, null=True)
[...]
objects = UserManager()
[...]
已添加个人资料模型
class Profile(models.Model):
user = models.OneToOneField(User, related_name='current_user', on_delete=models.CASCADE)
image = models.ImageField(default='default.jpg', upload_to='profile_pics')
def surname(self):
return self.user.surname}
def first_name(self):
return self.user.first_name
[...]
views.py:
@login_required
def profile_edit(request):
if request.method == 'POST':
p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile)
if p_form.is_valid():
p_form.save()
messages.success(request, f'Your account has been updated')
[...]
forms.py:
class ProfileUpdateForm(forms.ModelForm):
class Meta:
model = Profile
fields = ('first_name', 'surname')
template.html:
{% extends "base.html" %}
{% block content %}
<div>
<form method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ p_form }}
<button class="button" type="submit"> User update</button>
</form>
</div>
{% endblock content %}
通过浏览器访问模板时,我希望看到表单已经填充了配置文件(即用户)的名字和姓氏。相反,我在外壳中得到了django.core.exceptions.FieldError: Unknown field(s) (surname, first_name) specified for Profile
。

答案
用户ruddra的答案很好用,我已将其标记为我的问题的答案。不过,声明两个不同的表单对象并在模板中将它们打印出来也可以:
views.py:
u_form = UserUpdateForm(request.POST, instance=request.user)
p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile)
forms.py:
class UserUpdateForm(forms.ModelForm):
class Meta:
model = User
fields = ('first_name', 'surname')
class ProfileUpdateFormOld(forms.ModelForm):
class Meta:
model = Profile
fields = ('image',)
template.html:
{{ u_form }}
{{ p_form }}
答案 0 :(得分:2)
基本上,这些字段来自User
模型,但不在Profile
模型中。因此,您可以将ProfileUpdateForm
中的模型类更改为User
:
class ProfileUpdateForm(forms.ModelForm):
class Meta:
model = User
fields = ('first_name', 'surname')
根据评论更新答案:
class ProfileUpdateForm(forms.ModelForm):
first_name = forms.CharField(max_length=255)
surname = forms.CharField(max_length=255)
def __init__(self, *args, **kwargs):
super(ProfileUpdateForm, self).__init__(*args, **kwargs)
self.initial['first_name'] = self.instance.first_name()
self.initial['surname'] = self.instance.surname()
class Meta:
model = Profile
fields = ('first_name', 'surname')
def save(self, *args, **kwargs):
user = self.instance.user
user.first_name = self.cleaned_data.get('first_name')
user.surname = self.cleaned_data.get('surname')
user.save()
return super(ProfileUpdateForm, self).save(*args, **kwargs)
替代__init__(...)
方法的替代方法是在初始化表单时发送初始数据,并传递初始数据。例如:
个人资料= request.user.profile
ProfileUpdateForm(instance=profile, initial={'first_name':profile.first_name(), 'surname': profile.surname()})
