ModelForm数据不保存django [英] ModelForm data not saving django

问题描述

我已经阅读了关于表单数据不保存的其他帖子，但似乎无法确定自己的问题。有一种感觉，它的东西真的很基本，我失踪了。真的感谢帮助谢谢。

I've read the other posts on here about form data not saving, but can't seem to pinpoint my own problem. Have a feeling its something really basic I'm missing. Really appreciate the help thanks.

#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>

推荐答案

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：

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))
