python - 提交表单时HttpResponse不会显示 `post`信息

Question

我正在通过 Django 工作，并且正在创建一个应用程序，该应用程序将允许用户使用 ID 号登录系统。所以我有两个 View ，一个供用户登录，另一个供用户注册。前一个 View 工作得很好，我可以让它显示用户提交的信息。但是我无法让第二个 View 向用户显示 POST 数据:

from .forms import NameForm, IdForm
from django.shortcuts import render
from django.http import HttpResponse

def sign_in(request):

    if request.method == "POST":
        #here will construct the form with the POST data
        form = NameForm(request.POST)
        #the next part is to check that the information submitted is valid
        if form.is_valid():
            post = form.save()
            post.save()
            return HttpResponse(post)
        else:
            return HttpResponse("Form is invalid")
    else:
        form = NameForm()
    return render(request, 'checkin/base.html', {'form': form})



def sign_up(request):
    if request.method == "POST":
        form = IdForm(request.POST)
        if form.is_valid():
            post = form.save()
            post.save()
            return HttpResponse(post)
        else:
            return HttpResponse('Form is invalid')
    else:
        form = IdForm()
    return render(request, 'checkin/base.html', {'form': form})

基本上我想让回复是“谢谢，您的身份证号码是:post”。

这是我的模型的类:

from __future__ import unicode_literals

from django.db import models
from django import forms
from django.forms import ModelForm

# Create your models here.

class Question(models.Model):
    question_text = models.CharField("What is your ID?", max_length=200)

    id_text = models.CharField("Enter a new identification          
    number",max_length=200, null=True)

    def __str__(self):
        return self.question_text 

以下是两个 View 的表单类:

from django.forms import ModelForm
from .models import Question

#put the form here

class NameForm(ModelForm):
    class Meta:
        model = Question
        fields = ['question_text']

class IdForm(ModelForm):
    class Meta:
        model = Question
        fields = ['id_text']

Answer 1

将 POST 数据显示为用户的响应通常是 Not Acceptable 。那不是 HTML，只是普通用户无法理解的字典。在 Django(实际上是几乎所有 Web 框架)中使用表单的标准方法是向用户显示表单验证错误，以便他可以纠正它。

正确的方法

def sign_up(request):
    if request.method == "POST":
        form = IdForm(request.POST)
        if form.is_valid():
            post = form.save()
            post.save()
            return HttpResponseRedirect('/succes_url')
    else:
        form = IdForm()
    return render(request, 'checkin/base.html', {'form': form})
