Django - 使用表单自动填充django admin以外的字段created_by

Question

要求用户通过填充由modelformset_factory创建的表单来在django管理员之外创建新实例。问题是，我不知道如何将request.user传递给表单，以便在保存表单时created_by字段无效。

models.py：

from django.db import models 
from django.contrib.auth.models import User 

class ezApp(models.Model): 
    name = models.SlugField(max_length=50, unique=True) 
    date_created = models.DateTimeField('date created', auto_now_add=True) 
    date_updated = models.DateTimeField('date updated', auto_now=True) 
    created_by = models.ForeignKey(User) 
    in_use = models.BooleanField() 

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))

您可以在保存实例之前自己设定created_by领域。

做这样的事情：

if formset.is_valid(): 
    instances = formset.save(commit=False) 
    for instance in instances: 
     instance.created_by = request.user 
     instance.save()
