access to pk in a template form - django

Question

I want to display all elements of a form including the pk and I have not found a satisfying method to do so:
class SomeForm(forms.Form):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields["number"] = forms.IntegerField(required = True)
self.fields["id"] = forms.IntegerField(disabled = True)
self.fields["data"] = forms.CharField(required = False)
class Meta:
model = SomeModel
fields = ["id", "number", "data"]
So now I just call the form in the view with:
class SomeView(TemplateView):
template_name = "app/sometemplate.html"
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
obj = MODEL.objects.get(pk = context["pk"])
MODEL_data = {}
MODEL_data["number"] = obj.number
MODEL_data["id"] = obj.pk
MODEL_data["data"] = obj.data
context["form"] = SomeForm(initial = MODEL_data)
return context
and now in the templatetags I have a filter get_pk:
#register.filter(name='get_pk')
def get_pk(obj):
return obj.initial["id"]
and I get the pk in the template with {{ form|get_pk }} and I feel like this is not smart. I tried stuff like {{ form.instance.id }} like suggested here. I still feel there must be an easy way to achieve this?

I don't know why you need form in template view? You just need to get the context no more..
There are many comments in shared code like:
1-Disabled id field in initial form
2-Using different model name in form and get context data
3-Filtering context by using context["pk"] before assessing obj
Find the revised code,
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context["obj"] = SomeModel.objects.get(pk = the desired value)
return context
Note: if you want user to insert pk then you can use input field inside form with get method and get its value inside get context data in this way:
context["pk"] = self.request.GET.get("name of input field ")
In template html you can display fields directly:
{{obj.id}},{{obj.name}}, {{obj.data}}
