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，我已经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（因为它需要是只读的），并且无需用户提供输入即可自动填充数据。我读过django文档，但它仅指定动态初始化数据 see here。我曾尝试将这些代码放入Forms.py中，但没有用。

我什至尝试了HTML模板，但效果也不佳。

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

如何默认将数据获取到表单中？有人可以帮我吗？

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)

如何用用户数据填充（填充数据）模型表单？
