Question

我有一个这样的模型：

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

class Task(models.Model):

    title = models.CharField(max_length=200)
    pub_date = models.DateTimeField(default)
    completed = models.BooleanField(default=False)
    description = models.TextField()
    user = models.ForeignKey(User, on_delete=models.CASCADE)

    def summary(self):
        return self.description[:50]

    def pub_date_pretty(self):
        return self.pub_date.strftime('%b %e %Y')

    def __str__(self):
        return self.title

我有一个这样的forms.py，因为我不希望用户能够确定哪个用户正在保存数据，我希望pub_date成为现在的时间：

from django import forms
from .models import Task

from django.utils import timezone

class Taskform(forms.ModelForm):
    class Meta:
        model = Task
        fields = ['title', 'description', 'completed']

我的观点是这样的：

@login_required
def create(request):
    form = Taskform(request.POST or None)
    task = Task()
    task.pub_date = timezone.datetime.now()
    task.user = request.user

    if form.is_valid():
        form.save()
        return redirect('')

    return render(request, 'home/create.html', {'form': form})

我想将时间和用户传递给表单，因为它验证但我不确定如何？

您可以使用带有form.save()参数的commit=True来获取任务实例并进行更新：

if form.is_valid():
    task = form.save(commit=False)
    task.pub_date = timezone.datetime.now()
    task.user = request.user
    task.save()
    return redirect('')

Django将时间值和用户值传递给forms.py
