Question

我是Django的新手。我想创建一个简单的上传应用程序，其中用户将输入图像，价格和电子邮件ID的描述。并且想要显示描述文本和电子邮件以及图像。但是文本没有与图像一起出现。 See the final image after uploading

以下是我的代码：

Models.py

  # -*- coding: utf-8 -*-
from django.db import models

class Document(models.Model):

    docfile = models.FileField(upload_to='documents/%Y/%m/%d')

    description = models.CharField(max_length=255, blank=True)

    price = models.IntegerField(default=0)

    emailId = models.CharField(max_length=255, blank=True)



**forms.py**

    from django import forms


class DocumentForm(forms.Form):

    docfile = forms.FileField(
        label='Select a file',
    )
    description = forms.CharField(max_length=255)

    price = forms.IntegerField()

    emailId = forms.CharField(max_length=255) 

**views.py**

from django.template import RequestContext

from django.http import HttpResponseRedirect

from django.core.urlresolvers import reverse

from django.shortcuts import render

from django.shortcuts import render_to_response

from myapp.models import Document

from myapp.forms import DocumentForm

def list(request):

    if request.method == 'POST':

        form = DocumentForm(request.POST, request.FILES)

        if form.is_valid():

            newdoc = Document(docfile = request.FILES['docfile'])

            newdoc.save()


            return HttpResponseRedirect(reverse('list'))
    else:
        form = DocumentForm() # A empty, unbound form


    documents = Document.objects.all()


    return render(request,'myapp/list.html',{'documents': documents, 'form': form} )

def index(request):

    return render_to_response('myapp/index1.html')

**list.html**

{% load staticfiles %}

{% load static %}

<html>

  <head>

    <meta charset="utf-8">

    <title>Recent Uploads</title>

  </head>
  <body>

    <form action="{% url "list" %}" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Upload</button>
</form>

    <div id="wrapper">
      <section>
        {% if documents %}
        <ul id="gallery">
          {% for document in documents %}
          <li>
             <a href="{{ document.docfile.url }}">
              <img src="{{ document.docfile.url }}" alt=""></a>
              <p>
                <font color="black"> 
                  <p>Description : {{ document.description }}</p>
                  <p>Price :{{ document.price }}</p>
                  <p>Contact/Email-ID : {{ document.emailId }}</p>
            </font>
            </a>
          </li>
          {% endfor %}
        </ul>
        {% else %}
            <p>No documents.</p>
        {% endif %}
      </section>
    </div>
  </body>
</html>

您的表单不会将数据保存到数据库中。您需要继承forms.ModelForm而不是forms.Form。对于后者，您可能需要编写自己的自定义保存方法。 ModelForms隐含地为你做这件事。

forms.py，

class DocumentForm(forms.ModelForm):
    class Meta:
        model = Document
        fields = "__all__"

views.py，

def list(request):
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            doc = form.save(commit=False)
            doc.docfile = request.FILES['docfile']
            doc.save()
            return HttpResponseRedirect(reverse('list'))
    else:
        form = DocumentForm() 
    documents = Document.objects.all()
    return render(request,'myapp/list.html',{'documents': documents, 'form': form} )
