我正在使用在https://github.com/Chive/django-multiupload找到的Django的多上傳應用程序。Django中的模型表單是否需要表單具有forms.fieldtype格式？ form.save（）不適用於multipleupload
這似乎工作得很好，但我之前使用了一個模型表單，並用默認的multipupload字段替換了我之前的表單字段。
這似乎沒有模型的formfield。我的表單仍然以同樣的方式運行？
看來，form.save（）函數沒有采取相應的行動，我得到這個錯誤：

我知道，這是與事實多個文件被保存的形式做，但我不知道解決方案。
我的表格：
from django import forms
from uploads.models import Document,Sess
from multiupload.fields import MultiFileField
from pandas_sql import *
class DocumentForm(forms.models.ModelForm):
#docfile = forms.FileField(widget=forms.FileInput(attrs={
# 'class':'filestyle','data-classButton':"btn btn-primary",
# 'data-input':"false",'data-classIcon':"icon-plus",
# 'data-buttonText':"Upload Data",}))
docfile = MultiFileField(min_num=1, max_num=3, max_file_size=1024*1024*5)
is_multiple = forms.BooleanField(label='Multi-Gene List',required=False,widget=forms.CheckboxInput())
class Meta:
model=Document
fields=('docfile','is_multiple',)
def clean_docfile(self):
docfile = self.cleaned_data.get('docfile',False)
name = docfile.name
extension = os.path.splitext(name)[1]
if extension != '.xls' and extension != '.xlsx':
raise forms.ValidationError("only excel files allowed ")
if docfile._size<int("27000"):
raise forms.ValidationError("File Not Large Enough For Upload")
return docfile
def save(self,for_page):
self.instance.sess = for_page
return super().save()
，這裏是我的模型：
from django.db import models
from django.core.urlresolvers import reverse
class Sess(models.Model):
def get_absolute_url(self):
return reverse('view_page',args=[self.id])
class Document(models.Model):
docfile = models.FileField(upload_to='documents/%Y/%m/%d')
is_multiple = models.BooleanField(default=False)
sess = models.ForeignKey(Sess,default=None)
註釋的部分是我以前的代碼。我是否需要將表單文件還原爲標準表單文件或模型表單是否仍然有效？謝謝
您對模型的使用對我來說似乎有點奇怪。而不是在其中清晰地顯示模型字段中的'docfile'和'is_multiple'，我只會更改他們的小部件或任何必需的屬性。看到https://docs.djangoproject.com/en/1.8/topics/forms/modelforms/#overriding-the-default-fields並告訴我它是怎麼回事。 – Wtower
