Question

今天我在网页上有多个表单时遇到了很多麻烦。我的问题是对不同的URL进行表单操作。它能够使形式不同，所以即使是form.errors也会知道要显示的那个。我检查here，这是我去的地方，但仍然没有告诉我如何在views.py中定义它们之后如何在django模板中显示这些表格。

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，它们的表单将在同一页面中，所以假设我有{{form.name_of_term.errors}}，我不知道如何添加我显示的表单前缀html格式<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。我有一些很酷的答案，但它没有帮助我。

Answer 1

毕竟，我试过这个

{{ form1.name_of_term }}

简单地使它像魅力一样工作。虽然我不知道，我无法解释。我刚刚教过，因为我将其定义为form1，那么我应该能够检索表格
