Question

我已经阅读了其他关于表格数据未保存的帖子，但似乎无法查明我自己的问题。感觉它的东西非常基本我不见了。非常感谢帮助谢谢。

#model

class AboutMe(models.Model):
    title = models.CharField(max_length=30)
    user = models.ForeignKey(User)
    post = models.TextField()
    created = models.DateTimeField(auto_now_add=True)

    def __unicode__(self):
        return self.title

#form

class AboutMeForm(forms.ModelForm):

    class Meta:
        model = AboutMe
        fields = ['title', 'post']

#view


def post_line(request):
    if request.method == 'POST':
        form = AboutMeForm(request.POST)
        if form.is_valid():
            new_about = form.save(commit=False)
            new_about.user = request.user       
            new_about.save()
            return HttpResponseRedirect('index.html')
    else:
        form = AboutMeForm()
    return render_to_response('post_line.html', locals(), context_instance=RequestContext(request))

#template:

<div class="post_line">
<form enctype="multipart/form-data" action='.' method="post">{% csrf_token %}
    {{ form.as_table }}
    <input type="submit" name="submit" value="post" />
</form>
</div>

Answer 1

我无法在这里发表评论所以我在这里写作

1）HttpResponseRedirect('index.html')这里错了，你必须传递一些网址，如

/ login /或/ profile /

2）请打印您的表格，如

打印表单并检查您获得的是所有字段都有效或缺少任何字段

然后告诉表单错误

尝试这样做：

forms.py

class AboutMeForm(ModelForm):
    class Meta:
        model=AboutMe
        fields = YOUR FIELDS

    def __init__(self, *args, **kwargs):
        self.user = kwargs.pop('user', None)
        super(AboutMeForm, self).__init__(*args, **kwargs)

    def save(self, commit=True):
        instance = super(AboutMeForm, self).save(commit=False)
        if self.user:
            instance.user = self.user
        return instance.save()

在views.py上

：

def post_line(request):
    if request.method == 'POST':
        form = AboutMeForm(request.POST)
        if form.is_valid():
            new_about = form.save() 
            return HttpResponseRedirect('index.html')
    else:
        form = AboutMeForm()
    return render_to_response('post_line.html', locals(), context_instance=RequestContext(request))

ModelForm数据没有保存django
