Question

我有一个Django应用程序，其中包含公司列表，当用户点击公司时，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，以便任何使用都可以向公司添加标签，他们也可以搜索标签。我已经创建了表单和模板的东西，但现在我已经陷入了如何将其连接到View中，特别是使用新标签更新Company模型。

Forms.py

    <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>

模板

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

查看

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

更新

我得到的错误“'TagForm'对象没有属性'save'”。当我将窗体从forms.Form更改为forms.FormModel时，我收到以下错误“禁止创建没有'fields'属性或'exclude'属性的ModelForm;表单TagForm需要更新。”我不是要创建一个模型，而是通过表单更新它。

Taggit用于模型

<paper-drawer-panel id="paperDrawerPanel" force-narrow disable-swipe disable-edge-swipe ></paper-drawer-panel>

您可以做的一件事就是为标签创建一个简单的表单，就像您所做的那样，但删除Meta信息并更新post方法只是在公司中添加标签。如下所示：

# 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())
