有条件地显示具有DJANGO模板语言的按钮

如何解决有条件地显示具有DJANGO模板语言的按钮

我有一个页面，如果用户被标记为“可制造”（可计费），则该页面应显示一个按钮，否则，该按钮不应出现。我尝试了以下代码：

{% if form_experfil.facturable %}
     <a href="{% url 'incid:xtodo' %}?pagref=factdatshow" type="button"
                       class="btn btn-primary waves-effect"> Consultar datos de facturación</a>                      
{% endif %} 

但是它一直在显示。这种失败和其他失败使我认为{％if％}标签的行为并不像我想的那么简单，它不仅将html代码裁剪为endif标签，而且还首先呈现了某些内容。有没有正式记载而没有神秘参考的地方？是否有一种方法可以在客户拥有此数据时仅显示此按钮，而不显示其他数据？

这是视图：

def perfil_view(request):
perfil = ExUserProfile.objects.get(user=request.user)
facturar = perfil.facturable
if facturar:
    factdat = Factdat.objects.get(cliente=request.user)
if request.method == 'POST':
    form_perfil = perfilEditForm(data=request.POST,instance=request.user)
    form_experfil = experfilEditForm(data=request.POST,instance=perfil)
    if facturar:
        form_factdat = factdatEditForm(data=request.Post,instance=perfil)
    if all([form_perfil.is_valid(),form_experfil.is_valid(),form_factdat.is_valid()]):
        form_perfil.save()
        form_experfil.save()
        form_factdat.save(commit=facturar)
        return HttpResponseRedirect('incid/perfil')
else:
    form_perfil = perfilEditForm(instance=request.user)
    form_experfil = experfilEditForm(instance=perfil)
    if facturar:
        form_factdat = factdatEditForm(instance=factdat)
template = "incid/perfil.html"
if facturar:
    return render(request,template,{
        'form_perfil': form_perfil,'form_experfil': form_experfil,'form_factdat': form_factdat
    })
else:
    return render(request,'form_experfil': form_experfil
    })

这些是模型：

eclass ExUserProfile(models.Model):
user = models.OneToOneField(User,primary_key=True,on_delete=models.DO_NOTHING)
logo = ResizedImageField(size=[200,200],crop=['middle','center'],quality=75,upload_to='static/logos/',default='logos/no-img.jpg')
facturable = models.BooleanField(default=False)

def __str__(self):
    return str(self.user)


class Factdat(models.Model):
    cliente = models.OneToOneField(User,verbose_name='cliente_fact',default='',on_delete=models.DO_NOTHING)
    nomfact = models.CharField(max_length=240,verbose_name='nomfact')
    niffact = models.CharField(max_length=16,verbose_name='niffact')
    mailfact = models.EmailField(max_length=254,verbose_name='mailfact')
    telfact = models.CharField(max_length=24,verbose_name='telfact')
    persfact = models.CharField(max_length=128,verbose_name='persfact')

    class Meta:
        verbose_name = "Fact_dat"
        verbose_name_plural = "Fact_datos"

    def __str__(self):
        return str(self.cliente)

以防万一，这里是整页：

def perfil_view(request):
perfil = ExUserProfile.objects.get(user=request.user)
facturar = perfil.facturable
if facturar:
    factdat = Factdat.objects.get(cliente=request.user)
if request.method == 'POST':
    form_perfil = perfilEditForm(data=request.POST,'form_experfil': form_experfil
    })
