Question

我真的花了最后两天搜索如何在Django 2.0中上传单个文件，在实现它之后，我在前面的“上传多个文件”，文档还不够，我搜索了很多次没有任何结果。这是我的代码：

models.py：

from django.db import models

class Image(models.Model):
    title = models.CharField(max_length=40)
    image = models.ImageField()

    def __str__(self):
        return "{0} => {1}".format(self.id, self.title)

forms.py：

from django import forms
from . import models

class Image_Form(forms.ModelForm):
    class Meta:
        model = models.Image
        fields = "__all__"
        widgets = {
            "title": forms.TextInput(
                    attrs={
                        "required": "True",
                        "autofocus": "True",
                    }
                ),
            "image": forms.FileInput(attrs={'multiple': True}),
        }

views.py：

from django.shortcuts import render, redirect
from . import models, forms
from django.views.generic.edit import FormView

def index(request):
    all_images = models.Image.objects.all()
    image_form = forms.Image_Form()
    upload_files = Upload_Files()

    dico = {
        "images_key": all_images,
        "form_key": image_form,
        "upload_key": upload_files,
    }
    return render(request, "index.html", dico)

def media_upload(request):
    if request.method=="POST":
        upload_files = Upload_Files()
        upload_files.post(request)
    else:
        return redirect("index")

class Upload_Files(FormView):
    form_class = forms.Image_Form
    template_name="index.html"
    success_url = '/index/'

    def post(self, request, *args, **kwargs):
        form_class = self.get_form_class()
        form = self.get_form(form_class)
        files = request.FILES.getlist('image')
        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_invalid(form)

的index.html：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8"/>
        <title>index page</title>
    </head>
    <body>
        <form method="POST" action="{% url 'media_upload' %}" enctype="multipart/form-data">
        {% csrf_token %}
            <p>{{ form_key.title }}</p>
            <p>{{ form_key.image }}</p>
            <p><input type="submit" value="Save"/></p>
        </form>
        <hr/><hr/>
        {% for i in images_key %}
            <p>{{ i.title }}</p>
            <p><img src="{{ i.image.url }}"/></p>
            <hr/>
        {% endfor %}
    </body>
</html>

感谢您的帮助。谢谢:) :)

Answer 1

您的问题出在index.html上：您应该删除action="{% url 'media_upload' %}"，即更改

<form method="POST" action="{% url 'media_upload' %}" enctype="multipart/form-data">

到

<form method="POST" enctype="multipart/form-data">
