使用“接受”生成输入标签属性在Django窗体中使用FileField [英] Generating an input tag with "accept" attribute in Django form using FileField

问题描述

我想创建一个表单来上传和保存iOS Safari中的视频，它支持输入标签的accept属性，例如：

I want to create a form to upload and save videos from iOS Safari, which supports the "accept" attribute of the input tag, for example:

<input type=file accept="video/*">

可让您拍摄和上传新视频或在设备上选择一个视频文件。

lets you shoot and upload new video or select a video file on the device.

我已经看过Django文档： https://docs.djangoproject.com/en/dev/ref/forms/fields/#django.forms.FileField

I've looked at the Django docs at: https://docs.djangoproject.com/en/dev/ref/forms/fields/#django.forms.FileField

但是看不到我可以在哪里指定输入中的accept属性。这可能吗？我可以在模板中创建输入标签，还是使用Django表单处理来接受文件？

but don't see where I can specify the "accept" attribute on input. Is this possible? Can I create the input tag in the template and still use Django form processing to accept the file?

推荐答案

没有简单的方法为此，您可以在这个问题中看到一些很好的答案
此外，个人建议（未经测试）：创建表单后，设置您想要的任何属性，如

There is no easy way to do this, you can see some good answers in this question Also, a personal suggestion (untested): after creating the form, set whatever attributes you want on it like this

    for f in form.fields:
        if isinstance(form.fields[f].widget, ClearableFileInput):
            form.fields[f].widget.attrs['accept'] = 'video/*'
