如何不当前渲染django图像字段并清除内容? [英] How to not render django image field currently and clear stuff?

问题描述

我看了以下SO问题，但是没有运气.我不知道，也许我听不懂答案.

I took a look at following SO question, but had no luck. I don't know, maybe I didn't understand the answers.

1)如何在Django中删除当前"标签和FileInput小部件的链接?

2) Django ModelForm ImageField

我的表单:

class SettingsForm(forms.ModelForm):
    company_logo = forms.ImageField(label=_('Company Logo'),required=False, error_messages = {'invalid':_("Image files only")})
    class Meta:
        model = Settings
        fields = ("company_logo")
    ....

我的模型:

class Settings(models.Model):
    strg=CustomFileSystemStorage(strict_name='images/company_logo.png',save_format='PNG')
    company_logo=models.ImageField(upload_to='images',blank=True,null=True,storage=strg)
    .....

渲染后:

我从第一个链接中看到， models.ImageField 继承了 FileInput 并添加了额外的内容，但是我不知道如何克服这个问题?

I see from the first link, that the models.ImageField inherits the FileInput and adds the extra stuff, but I do not understand how to overcome this?

先谢谢了.

推荐答案

解决方案是:

class SettingsForm(forms.ModelForm):
    company_logo = forms.ImageField(label=_('Company Logo'),required=False, error_messages = {'invalid':_("Image files only")}, widget=forms.FileInput)
    class Meta:
        model = Settings
        fields = ("company_logo")
    ....

我添加了小部件 forms.FileInput ，以告知ImageField使用基本字段，而不是从 FileInput 继承的字段.

I added the widget forms.FileInput, in order to tell the ImageField to use the basic field, not the one inherited from FileInput.
