昨天我问了这个问题。

然后我找到了这个片段：

模型.py

from django.db import models
from app.extra import ContentTypeRestrictedFileField

class upload(models.Model):
    """ upload """
    name = models.CharField(max_length=100)
    description = models.CharField(max_length=250)
    file = ContentTypeRestrictedFileField(
        upload_to='/media/videos,'
        content_types=['video/avi', 'video/mp4', 'video/3gp', 'video/wmp', 'video/flv', 'video/mov'],
        max_upload_size=104857600
    )
    created = models.DateTimeField('created', auto_now_add=True)
    modified = models.DateTimeField('modified', auto_now=True)

    def __unicode__(self):
        return self.name

表格.py

from django.db.models import FileField
from django.forms import forms
from django.template.defaultfilters import filesizeformat
from django.utils.translation import ugettext_lazy as _

class ContentTypeRestrictedFileField(FileField):
    """
    Same as FileField, but you can specify:
        * content_types - list containing allowed content_types. Example: ['application/pdf', 'image/jpeg']
        * max_upload_size - a number indicating the maximum file size allowed for upload.
            2.5MB - 2621440
            5MB - 5242880
            10MB - 10485760
            20MB - 20971520
            50MB - 5242880
            100MB 104857600
            250MB - 214958080
            500MB - 429916160
    """
    def __init__(self, content_types=None,max_upload_size=104857600, **kwargs):
        self.content_types = kwargs.pop('video/avi', 'video/mp4', 'video/3gp', 'video/wmp', 'video/flv', 'video/mov')
        self.max_upload_size = max_upload_size

        super(ContentTypeRestrictedFileField, self).__init__(**kwargs)


    def clean(self, *args, **kwargs):        
        data = super(ContentTypeRestrictedFileField, self).clean(*args, **kwargs)

        file = data.file
        try:
            content_type = file.content_type
            if content_type in self.content_types:
                if file._size > self.max_upload_size:
                    raise forms.ValidationError(_('Please keep filesize under %s. Current filesize %s') % (filesizeformat(self.max_upload_size), filesizeformat(file._size)))
            else:
                raise forms.ValidationError(_('Filetype not supported.'))
        except AttributeError:
            pass        

        return data

        from south.modelsinspector import add_introspection_rules
        add_introspection_rules([], ["^app\.extra\.ContentTypeRestrictedFileField"])

并添加这一行是settings.py

FILE_UPLOAD_MAX_MEMORY_SIZE = 157286400 # 157286400 bytes = 150 MB

我刚刚发现了一个名为Django-crispy forms的应用程序。他们给你这个片段来创建这个表单

我的问题是：

是否可以将我的代码片段与 django-crispy 结合起来创建一个看起来像这样的表单？我知道我必须使用django-tagging。

看看 django 给出的 css 选择器是什么形式。然后使用你的样式表来改变它的外观。您甚至可以自己设置选择器，请参阅文档以获取更多信息。
