ImageField / FileField Django表单目前无法修剪文件名的路径

问题描述 投票:1回答:1

我有一个存储在AWS S3中的ImageField(类似于FileField)。在表单中,它具有显示图像文件路径的“当前”标签。我想修剪,只显示文件名。

谈到Django : customizing FileField value while editing a model的最新答案,我仍然无法让它发挥作用。

它显示“Currently”,文件路径名如下:https://imgur.com/a/xkUZi

form.朋友

class CustomClearableFileInput(ClearableFileInput):
    def get_template_substitution_values(self, value):
        """
        Return value-related substitutions.
        """
        logging.debug("CustomClearableFileInput %s",value) <-- it never came here
        return {
            'initial': conditional_escape(path.basename(value.name)),
            'initial_url': conditional_escape(value.url),
        }

class CompanySettingEdit(forms.ModelForm):
    display_companyname = forms.CharField(max_length=50, required=True)    
    company_logo = forms.ImageField(widget=CustomClearableFileInput)

    class Meta:
        model = Company
        fields = ("display_companyname","company_logo")

model.朋友

class Company(models.Model):
    display_companyname = models.CharField(max_length=50)    
    company_logo = models.ImageField(upload_to=upload_to('company_logo/'), blank=True, null=True, storage=MediaStorage())

我怎么能有这样的东西:目前:filename.jpg

仅供参考 - ImageField / FileField,我试过它并没有什么区别。我使用Django == 1.11.7

python django django-forms django-file-upload django-1.11

在Django 1.11.x中,get_template_substitution_values已被弃用。 CustomClearableFileInput的新实施可以如下:

class CustomClearableFileInput(ClearableFileInput):
    def get_context(self, name, value, attrs):
        value.name = path.basename(value.name)
        context = super().get_context(name, value, attrs)       
        return context
