Question

我已经创建了一个模型表单。我想在网页上显示它并将表单数据推送到数据库中：下面是模型和视图。这里应该由db自动生成topic_id和command_id。如果我创建的视图是正确的，请告诉我。

谢谢，阿伦

models.py

from django.db import models
# Create your models here.
from django.forms import ModelForm

class Topics(models.Model):
    topic_id = models.AutoField(primary_key=True)
    topic_name = models.CharField(max_length=200)
    def _unicode_(self):
        return self.name

class Command(models.Model):
    command_id = models.AutoField(primary_key=True)
    title = models.CharField(max_length=200)
    command = models.CharField(max_length=200)
    description=models.CharField(max_length=200)
    topic_under=models.ForeignKey(Topics)
    def _unicode_(self):
        return self.name

class TopicsForm(ModelForm):
    class Meta:
        model = Topics

class CommandForm(ModelForm):
    class Meta:
        model = Command

views.py

# Create your views here.
from command.models import Command
from command.models import CommandForm
from django.shortcuts import render_to_response, get_object_or_404
from django.template import RequestContext
from django.core.context_processors import csrf

def submitform(request):
    if request.method == "POST":
        form = CommandForm()
        if form.is_valid():
           form.save()
           return render(request, 'newcommand.html')
    else:
        form = CommandForm()
        return render(request, 'inputtest.html', {'form': form})

Answer 1

在以下块中：

form = CommandForm()
if form.is_valid():
   form.save()
   return render(request, 'newcommand.html')

将form = CommandForm()替换为form = CommandForm(request.POST)

这将解决它。无论如何，你应该尝试基于通用类的视图，因为它们更强大和标准。您可以了解他们here。看一下ListView，CreateView，UpdateView和DeleteView（a.k.a.CRUD）
