如何将用户字段数据和用户配置文件数据绑定到视图上的模型表单,当我使用instance = user时,我只能将用户数据呈现给表单,但不能在实例上呈现用户配置文件的任何数据= profile,我需要将所有用户及其个人资料呈现为表单。
models.py
class User(AbstractUser):
is_supervisor = models.BooleanField(default=False)
is_student = models.BooleanField(default=False)
class Supervisor(models.Model):
user = models.OneToOneField('User', on_delete=models.CASCADE, primary_key=True, related_name='supervisor')
su_mobile_number = models.CharField(max_length=200)
view.py
def supervisor_update(request, user_id):
# user = get_object_or_404(User, pk=user_id)
user = get_object_or_404(User, pk=user_id)
profile = get_object_or_404(Supervisor, pk=user_id)
if request.method == 'POST':
form = SupervisorSignUpForm(request.POST, instance=user)
else:
form = SupervisorSignUpForm(instance=user)
return save_user_form(request, form, 'partials/partial_supervisor_update.html')
form.py
class SupervisorSignUpForm(UserCreationForm):
su_mobile_number = forms.CharField(label="Mobile Number")
class Meta(UserCreationForm.Meta):
model = User
fields = ('username', 'email', 'password1', 'password2', 'first_name', 'last_name')
supervisor_update.html
{% load crispy_forms_tags %}
<form method="post" action="{% url 'supervisor_update' form.instance.pk %}" class="js-supervisor-update-form">
{% csrf_token %}
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title">Update Supervisor</h4>
</div>
<div class="modal-body">
{% include 'partials/form_messages.html' %}
{{ form.username|as_crispy_field }}
{{ form.email|as_crispy_field }}
{{ form.first_name|as_crispy_field }}
{{ form.last_name|as_crispy_field }}
{{ form.su_mobile_number|as_crispy_field }}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-primary">Update Supervisor</button>
</div>
</form>

设置与用户实例一起传入的额外字段应该起作用
initial = {'su_mobile_number': profile.su_mobile_number}
form = SupervisorSignUpForm(instance=user, initial=initial)
或者,如果您不想手动创建字典,则可以使用model_to_dict
from django.forms.models import model_to_dict
initial = model_to_dict(profile, exclude=['user'])
form = SupervisorSignUpForm(instance=user, initial=initial)
在视图的顶部,您还假设用户和主管具有相同的ID(事实并非如此),您可以这样做
user = user = get_object_or_404(User, pk=user_id)
profile = user.supervisor
if not profile:
raise Http404
