Question

要求用户填写由modelformset_factory创建的表单，在django admin之外创建一个新实例。问题是我不知道如何将request.user传递给表单，因此在保存表单时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置created_by字段。

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()
