Question

上传到默认django db的简单图像永远不会完成。该错误似乎表明图像字段出现问题，就像我的views.py打印form.errors，它返回

image

此字段是必填字段。

这是我的代码，我只上传了我认为可能影响它的内容。

models.py

class Image(models.Model):
     name = models.CharField(max_length=128, unique=True)
     image = models.ImageField(upload_to="user_images")
     slug = models.SlugField(unique=True)

    def save(self, *args, **kwargs):
       self.slug = slugify(self.name)
       super(Image, self).save(*args, **kwargs)

   def __unicode__(self):
       return self.name

forms.py

from django import forms
from shareIt.models import Image

class ImageForm(forms.ModelForm):
    name = forms.CharField(max_length=128, help_text="Please enter an image name")
    image = forms.ImageField()
    slug = forms.CharField(widget=forms.HiddenInput(), required=False)

class Meta:
    model = Image
    fields = ('name', 'image')

views.py

def uploadImage(request):

if request.method== 'POST':
    form = ImageForm(request.POST, request.FILES)
    if form.is_valid():
        form.save(commit=True)
        return images(request)
    else:
        print form.errors
else:
    form = ImageForm()

contextdict = {"form": form}
return render(request, 'uploadImage.html', contextdict)

uploadImage.html

<html>
<form id="upload" action="/share/images/upload" method="post">
    {% csrf_token %}
    {{ form.as_p }}

<input type="submit" name="submit", value="upload image" />
</form>

Answer 1

将enctype属性添加到<form>代码：

<form id="upload" action="/share/images/upload" enctype="multipart/form-data" method="post">

Answer 2

使用模型表单时，无需键入：

name = forms.CharField(max_length=128, help_text="Please enter an image name")
image = forms.ImageField()
slug = forms.CharField(widget=forms.HiddenInput(), required=False)

您的模型中已有此功能。你只需要这个：

class ImageForm(forms.ModelForm):
    class Meta:
        model = Image
        fields = ('name', 'image')

Django图像上传总是失败，表单永远不会有效
