Gestern fragte ich diese question.Django-crispy Upload-Formulare
Ich fand dann diese Schnipsel:
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.

Ich habe gerade über eine App Django-crispy forms rief. Sie geben Ihnen this snippetthis form
Meine Frage zu schaffen:
Ist es möglich, meine Schnipsel mit django-knusprig zu kombinieren, um eine Form zu schaffen, die wie folgt aussieht? Ich weiß, dass ich django-tagging verwenden muss.
