how to call get_foo_display in html page-CodePudding

I want to show in ListView human redable format instead of actual values. Like

From this

| fc_mo | c_serv |
| ---   | ---    |
| 1     | 5      |

To this

| fc_mo | c_serv     |
| ---   | ---        |
| 1     | cardiology |

Or to check it values

I tried to call it in several ways, but it always get no data from it. It only worked in a shell. Please can someone show me example of using get_FOO_display().There is very little information in the django documentation about this

model.py

class LicAppNew(models.Model):
  id_prof = models.AutoField(primary_key=True, serialize=True)
  fc_mo = models.CharField(max_length=8, choices=FC_MO_CHOICES)
  name = models.CharField(max_length=280, blank=True, null=True, choices=FC_NAME_CHOICES_2)
  date_b = models.DateField(blank=True, null=True, default='01.04.2022')
  idpr = models.IntegerField(blank=True, null=True, choices=IDPR_CHOICES)
  disp = models.CharField(max_length=10, blank=True, null=True)
  date_e = models.DateField(blank=True, null=True, default='01.01.2070')
  lic_num = models.CharField(max_length=255, blank=True, null=True)
  c_serv = models.IntegerField(blank=True, null=True, choices=C_SERV_CHOICES)
  deleted = models.BooleanField(default=False, blank=True, null=True)

class Meta:
    managed = True
    db_table = 'lic_app_new'
    #ordering = ['fc_mo']
    ordering = ['fc_mo','c_serv']


#def __str__(self):
   # return self.name()


def get_absolute_url(self):
    return f'/app/{self.id_prof}'

views.py

class LicAppNew_view(ListView):
  model = LicAppNew
  template_name = 'app/LicView_view.html'
  queryset = LicAppNew.objects.all()

class AppLicUpdateView(UpdateView):
    model = LicAppNew
    template_name = 'app/detail_app_view.html'
    form_class = LicAppNewForm
    success_url = '/app/'

CodePudding user response：

get_FOO_display is a django model instance "magic" method, not a form attribute. Also, Django template language invokes functions which don't have arguments, but you don't call them with brackets. So not {{form.get_c_serv_display()}}

You possibly want {{form.instance.get_c_serv_display}} if form is a ModelForm. Otherwise you will have to pass instance explicitly in the context, if it's not already there (It probably is there, as the default object of LicAppView, so {{object.get_c_serv_display}} )
