django - 使用modelformset_factory填充created_by字段与request.user中查看

Question

我使用modelformset_factory创建一个空的表单，但我不知道如何在视图中使用request.user填充created_by字段。我知道可以使用models.Manager来处理created_by的默认值，但我更愿意用当前登录的用户直接在视图中填充它。我不在乎管理界面。

这是我的models.py：

from django.db import models 
from django.forms import ModelForm 
from django.contrib.auth.models import User 
import datetime 

class ezApp(models.Model): 
    name = models.SlugField(max_length=50,) 
    date_created = models.DateTimeField('date created', editable=False) 
    date_updated = models.DateTimeField('date updated', editable=False) 
    created_by = models.ForeignKey(User) 

def save(self): 
    if not self.id: 
     self.date_created = datetime.date.today() 
    self.date_updated = datetime.datetime.today() 
    super(ezApp, self).save() 

class ezForm(ModelForm): 
    class Meta: 
     model = ezApp 
     fields = ('name') 

这个views.py

from django.shortcuts import render_to_response 
from ezmapping.models import * 
from django.forms.models import modelformset_factory 

def setName(request): 
    ezAppFormSet = modelformset_factory(ezApp, extra=1, fields=('name')) 
    formset = ezAppFormSet(queryset=ezApp.objects.none()) 
    if request.method == 'POST': 
     formset = ezAppFormSet(request.POST, request.FILES) 
     if formset.is_valid(): 
      formset.save() 
    return render_to_response("project/manage_new.html", {'formset': formset, 'title': "New"}, context_instance=RequestContext(request)) 

错误消息：

project_ezapp.created_by_id不能为null

我想你可以试试：

class BaseEzAppFormSet(BaseModelFormSet): 
    def __init__(self, *args, **kwargs): 
     self.user = kwargs.pop('user') 
     super(BaseEzAppFormSet, self).__init__(*args, **kwargs) 

    def save_new(self, form, commit=True): 
     obj = form.save(commit=False) 
     obj.created_by = self.user 
     if commit: 
      obj.save() 
     return obj 
... 
ezAppFormSet = modelformset_factory(ezApp, extra=1, fields=('name'), 
    formset=BaseEzAppFormSet) 
... 
formset = ezAppFormSet(request.POST, request.FILES, user=request.user)
