如何使用用户数据填充（填充数据）模型？

Question

这是我的models.py。

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

class User_data(models.Model):

    user_ID = models.CharField(max_length = 20)
    name = models.CharField(max_length = 50)
    user = models.ForeignKey(User, on_delete = models.CASCADE, null =True)

    def __str__(self):
        return self.name

这是我的forms.py

from django import forms
from lrequests.models import User_data

class UserForm(forms.ModelForm): 
    class Meta:
        fields = ("name", "user_ID")

        model = User_data

这是我的views.py

from django.shortcuts import render
from django.http import HttpResponse
from .forms import UserForm
from django.shortcuts import render_to_response
from .models import User_data

def get(request):
    form_class = UserForm
    if request.method == "POST":
        form = UserForm(request.POST)
        if form.is_valid():
            data = form.save(commit = False)
            data.user = request.user
            form.save()
        return HttpResponse("Sucessfully submitted")
    else:
        form = UserForm()
        return render(request, "request_form.html", {'form' : form_class})

#update
def auto_fill_form(request):
form = UserForm(initial = dict(name = request.user.first_name))
context = dict(form=form)
return render(request, "request_form.html", context)

现在，我尝试填充在创建帐户时指定的用户数据。因此，他（用户）不会篡改数据（因为它需要只读）并且它会自动填充而无需用户提供输入。我已阅读 django 文档，但它仅指定动态初始化数据 see here。我试过将该代码放入 forms.py，但没有成功。

我什至在 HTML 模板中尝试过，也没有用。

            {% csrf_token %}
            <div class="form-row">
                {{ form.name.errors }}
                {{ form.name.label_tag }} {{ form.name = user.first_name }}
            </div>
            {% comment %} {{ form.as_p }} {% endcomment %}

默认情况下如何将数据获取到表单中？有人可以帮我解决这个问题吗？

Answer 1

只需更换

else:
    form = UserForm()
    return render(request, "request_form.html", {'form' : form_class})

作者：

else:
    return auto_fill_form(request)
