如何在django模板中应用表单前缀

Question

今天我在一个页面中有多个表单时遇到了很多麻烦。我的问题是对不同的 url 执行表单操作。它能够改变形式，所以即使 form.errors 也知道要显示的那个。我检查了 here，这是我去的地方，但仍然没有告诉我如何在 views.py 中定义这些表单后在 django 模板中显示它们。

这是我的观点

def TermAdd(request):
    if request.method == 'POST':
        form1 = SchoolFirstTermForm(request.POST, prefix="form1", request=request)
        form2 = SchoolSecondTermForm(request.POST, prefix="form2", request=request)
        form3 = SchoolThirdTermForm(request.POST, prefix="form3", request=request)
        if form1.is_valid() and form2.is_valid() and form3.is_valid():
            if 'term_add_button' in request.POST:
                myterm = form1.save(commit=False)
                myterm.session = session_dates
                myterm.save()
                messages.add_message(request, messages.SUCCESS, ("Administrator %s, The %s for %s Sessions were added successfully") % (request.user, myterm.name_of_term, session_dates.current_session))
                return HttpResponseRedirect(reverse('school_session.views.SchoolTermAddView'))
    else:
        form1 = SchoolFirstTermForm(prefix="form1")
        form2 = SchoolSecondTermForm(prefix="form2")
        form3 = SchoolThirdTermForm(prefix="form3")
    context = {'form1':form1, 'form2':form2, 'form3':form3, 'session_dates':session_dates, 'term_dates':term_dates}
    return render_to_response('schools/admin_term_add.html', context, context_instance=RequestContext(request))

这里是models.py

class SchoolFirstTerm(models.Model):
    session = models.ForeignKey(SchoolSession)
    name_of_term = models.CharField(verbose_name="Name of Term", max_length=15, help_text="leave this except you want to change the name of your First Term to another word")
    term_start = models.DateField()
    term_end = models.DateField()
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

    def __unicode__(self):
        return "%s Term of %d/%d session" % (self.name_of_term, self.session.current_session)

class SchoolSecondTerm(models.Model):
    session = models.ForeignKey(SchoolSession)
    name_of_term = models.CharField(verbose_name="Name of Term", max_length=15, help_text="leave this except you want to change the name of your First Term to another word")
    term_start = models.DateField()
    term_end = models.DateField()
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

    def __unicode__(self):
        return "%s Term of %d/%d session" % (self.name_of_term, self.session.current_session)

class SchoolThirdTerm(models.Model):
    session = models.ForeignKey(SchoolSession)
    name_of_term = models.CharField(verbose_name="Name of Term", max_length=15, help_text="leave this except you want to change the name of your First Term to another word")
    term_end = models.DateField()
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

    def __unicode__(self):
        return "%s Term of %d/%d session" % (self.name_of_term, self.session.current_session)

三个模型共享相同的字段，并且它们的表单要在同一页中，所以假设我有{{ form.name_of_term.errors }}，我不知道如何添加我的表单前缀以 html 格式显示 <input type="text" name="form1-name_of_term" id="id_form1-name_of_term" />

我尝试了这个 {{ form.prefix }}{{ form.name_of_term }} 并且还阅读了一些答案，例如 How can I build multiple submit buttons django form?, Django: Display form name in template with prefix。我在那里得到了一些很酷的答案，但对我没有帮助。

Answer 1

毕竟我试过这个

{{ form1.name_of_term }}

只是让它像魅力一样工作。虽然我不知道也无法解释。我只是教过，既然我把它定义为 form1，那么我应该能够检索到
