Python Django无法上载图像文件

我在模型中尝试ImageField，但当我尝试从表单上载时，图像上载不起作用。但是当我从管理页面上传它时，它就工作了

任何调试的方法都是有帮助的

我的模型-

class Inventory(models.Model):
    """docstring for Inventory"""
    name = models.CharField(max_length=100,default='Something')
    image = models.ImageField(null=True, blank=True)
    description = models.CharField(max_length=100, default='Describe Something')
    price = models.IntegerField( default=0)

我的表格-

class InventoryForm(forms.ModelForm):
    class Meta:
        model = Inventory
        fields = ['name','description','price','image']

        widgets = {
            'name' : forms.TextInput(attrs={"placeholder":"Name", "onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
            'description' : forms.TextInput(attrs={"placeholder":"Email", "onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
            'price' : forms.NumberInput(attrs={"placeholder":"Price","onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
            
        }

背景-

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, "media/")

模板-

<form action="" method="post" enctype="multipart/form-data">  {% csrf_token %}
    {{form}}
    <input type="submit" value="Send">
</form>

问候,，

如何在图像字段中向模型中添加upload_并添加默认图像？这将在以后派上用场，无论您是否选择：

models.py

class Inventory(models.Model):
    """docstring for Inventory"""
    name = models.CharField(max_length=100,default='Something')
    image = models.ImageField(upload_to='/your_file_name/',default='default.png')
    description = models.CharField(max_length=100, default='Describe Something')
    price = models.IntegerField(default=0)

---

在您的视图中.py。更改：

form=InventoryForm（request.POST或None）

到

form=InventoryForm（request.POST、request.FILES或None）

---

因为，django post请求中的文件位于request.Files字典中。您还必须将其发送到表单。

问题可能出在您的views.py中。使用

request.Files

接收文件。确保您没有对文件使用

request.POST

，我添加了views.py文件，我也添加了下面的答案，我可以尝试一下，但这不是一个好的做法。我想使用媒体url和媒体设置

def index(request):
    form = InventoryForm(request.POST or None)
    if form.is_valid():
        form.save()
        form = InventoryForm()
    else:
        form = InventoryForm()

    inventory = Inventory.objects.all()
    context = {'form' : form, 'all_inventory' : inventory}
    return render(request, 'inventory/index.html',context)

models.py

class Inventory(models.Model):
    """docstring for Inventory"""
    name = models.CharField(max_length=100,default='Something')
    image = models.ImageField(upload_to='/your_file_name/',default='default.png')
    description = models.CharField(max_length=100, default='Describe Something')
    price = models.IntegerField(default=0)
