title: HttpResponse won't display `post` information when submitting a form
body: <p>I'm working my way through Django and I'm creating an app that will allow users to use an ID number to sign-in to a system. So I have two views, one for users to log-in, and the other to sign-up. The former view works just fine, I can get it to display the information the user has submitted. However I can't get the second view to display the <code>POST</code> data to the user: </p>
  
  <pre><code>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})
  </code></pre>
  
  <p>Basically I want to make the response to be "thank you, your ID number is: <code>post</code>". </p>
  
  <p>Here is the class for my model: </p>
  
  <pre><code>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 
  </code></pre>
  
  <p>And here are the form classes for both views:</p>
  
  <pre><code>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']
  </code></pre>
