怎么可以在django中保存manytomany字段？

本文介绍了怎么可以在django中保存manytomany字段？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

models.py：

models.py:

class Tag(models.Model): name = models.CharField(max_length=100) description = models.CharField(max_length=500, null=True, blank=True) created = models.DateTimeField(auto_now_add=True) modified = models.DateTimeField(auto_now_add=True) class Post(models.Model): user = models.ForeignKey(User) tag = models.ManyToManyField(Tag) title = models.CharField(max_length=100) content = models.TextField() created = models.DateTimeField(default=datetime.datetime.now) modified = models.DateTimeField(default=datetime.datetime.now) def __unicode__(self): return '%s,%s' % (self.title,self.content) class PostModelForm(forms.ModelForm): class Meta: model = Post class PostModelFormNormalUser(forms.ModelForm): class Meta: model = Post widgets = { 'tag' : TextInput() } exclude = ('user', 'created', 'modified') def __init__(self, *args, **kwargs): super(PostModelFormNormalUser, self).__init__(*args, **kwargs) self.fields['tag'].help_text = None

我在views.py中尝试了（看起来不正确的方式）

what i tried in views.py: (that doesn't look the correct way)

if request.method == 'POST': form = PostModelFormNormalUser(request.POST) print form print form.errors tagstring = form.data['tag'] splitedtag = tagstring.split() if form.is_valid(): temp = form.save(commit=False) temp.user_id = user.id temp.save() post = Post.objects.get(id=temp.id) l = len(splitedtag) for i in range(l): obj = Tag(name=splitedtag[i]) obj.save() post.tag.add(obj) post = Post.objects.get(id=temp.id) return HttpResponseRedirect('/viewpost/' + str(post.id)) else: form = PostModelFormNormalUser() context = {'form':form} return render_to_response('addpost.html', context, context_instance=RequestContext(request))

任何人都可以发布示例完成代码编辑，以保存到Post表，标签表和post_tag表？

Can anyone post example complete code editing this to save into Post table, Tag table and post_tag table?

输入表单将包含一个文本框以键入'title'和texarea for 'content'和一个文本框，键入'tag'作为字符串。标签字符串由空格分隔。我需要将这些标记词保存到Tag表中，并在post_tag表中映射。

The input form will contain a textbox to type 'title' and texarea for 'content' and a textbox to type 'tag' as string. The tag string is seperated by space. I need to save those tag words into Tag table and map in post_tag table.

我该怎么做？

推荐答案

如果你想标注标签，你可以使用django-tagging或django-taggit

As an aside, if you're implimenting tagging, you could just use django-tagging or django-taggit
