昨天我問了這個question。Django-crispy上傳表格
然後我發現這個片斷：
models.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
form.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"])
，並添加此行是settings.py
FILE_UPLOAD_MAX_MEMORY_SIZE = 157286400 # 157286400 bytes = 150 MB
我只是發現了關於所謂Django-crispy forms的應用程序。他們給你this snippet創建this form
我的問題是：
是否有可能我的片段與Django的香脆創建一個表單，看起來像這樣結合？我知道我必須使用django-tagging。
