Django如何将taggit标签添加到模板中的模型

Question

我有一个拥有公司列表的Django应用程序，当用户点击一家公司时，他们会看到该公司的所有详细信息。现在我正在尝试添加标签功能，以便任何使用可以将标签添加到公司，他们也可以搜索。我创建了表单和模板的东西，但是现在我被困在如何将它连接到View中，特别是使用新标签更新公司模型。

Forms.py

class TagForm(forms.Form): 
    tag = forms.CharField(label='Tag', max_length=100) 

    class Meta: 
     model = Company 
     field = 'tag' 

模板

<div class="add-tag-form"> 
     <form method="POST" class="post-form">{% csrf_token %} 
      {{ form.as_p }} 
      <button type="submit" class="save btn btn-default btn-sm">Add</button> 
     </form> 
    </div> 

查看

class CompanyDetails(generic.DetailView): 
    model = Company 
    template_name = 'company_details.html' 

    # This was my attempt to work it into the View... 
    def post(self, request, *args, **kwargs): 
     form = TagForm(request.POST) 
     if form.is_valid(): 
      tag = form.save(commit=False) 
      tag.company = Company.objects.get(pk=pk) 
      tag.save() 

    def get_context_data(self, **kwargs): 
     pk = self.kwargs.get('pk') 
     context = super(CompanyDetails, self).get_context_data(**kwargs) 
     context['articles'] = Articles.objects.filter(company_id=pk).order_by('-date') 
     context['transcripts'] = Transcripts.objects.filter(company_id=pk).order_by('-date') 
     context['form'] = TagForm() 

     # Yahoo Finance API data 
     stock_symbol = self.object.stock_symbol 
     data = Share(stock_symbol) 
     stock_open = data.get_open() 
     year_range = data.get_year_range() 
     fifty_day_moving_average = data.get_50day_moving_avg() 
     market_cap = data.get_market_cap() 

     yahoo_finance = dict() 
     yahoo_finance['stock_open'] = stock_open 
     yahoo_finance['year_range'] = year_range 
     yahoo_finance['fifty_day_moving_average'] = fifty_day_moving_average 
     yahoo_finance['market_cap'] = market_cap 
     context['yahoo_finance'] = yahoo_finance 

     # Yahoo News RSS data 
     yahoo_news = feedparser.parse("http://finance.yahoo.com/rss/headline?s=" + stock_symbol) 
     yahoo_news = yahoo_news['entries'] 
     for item in yahoo_news: 
      item['published'] = datetime.strptime(item['published'], '%a, %d %b %Y %H:%M:%S %z') 

     context['yahoo_news'] = yahoo_news 

     return context 

UPDATE

我得到的错误“'TagForm'对象没有'save'属性。当我将forms从form.Form更改为forms.FormModel时，出现以下错误：“禁止创建没有'fields'属性或'exclude'属性的ModelForm; TagForm需要更新。”我没有试图创建一个模型，而是通过表单更新它。

Taggit在模型

class Company(models.Model): 
company_name = models.CharField(max_length=200) 
tags = TaggableManager()

一件事，你可以做用是作一个简单的形式为标记，就像你做了什么，但删除的元信息和更新后的方法，只是在公司中添加标签。像下面这样：

# forms.py 
class TagForm(forms.Form): 
    tag = forms.CharField(label='Tag', max_length=100) 

# views.py 
class CompanyDetails(generic.DetailView): 
    ... 

    # This was my attempt to work it into the View... 
    def post(self, request, *args, **kwargs): 
     company = self.get_object() 
     form = TagForm(request.POST) 
     if form.is_valid(): 
      company.tags.add(form.cleaned_data['tag']) 

     return self.render_to_response(self.get_context_data())
