Override def get_context_data()
It returns kwargs in which you can pass fields to use in your template

btw its get_context_data()

I guess the get_context_data would be bonded to return at form_valid().
Or could you show an example

Thanks, I understand this perfectly. The issue is am working with formview. How do I pass data to context right inside the form_valid function

Do you mean for example a validated data ?
You are working with a Python class , aren't you ?
So define a class attribute , set as you need inside form_valid, then use it into your get_context_data as you would do with every class field into a class method
Ghorz
Okay
Ghorz
If you look the code clearly on line 10

How will results be passes to context data
Anonymous
guys can it possible django model status change just a button click
Ghorz
It is not a model data. Instead data from a form was passed to a function. I want to return the results sets to a context data so I can display it in my template

That's why it's important to know Python before Django

That's why it's important to know Python before Django
Yea I coded python for 4years before I tried django. I hated OOP as a C programmer until I started with python. Even while working with python, i used pure function. Django made me create a tiny space in my heart for oop
Ghorz
since to work now but results resets to None in get_context_data

Hi Guys! I want to know which is better to learn: django or nodejs? I am proficient at C language only. I don't knlow anything much about Python or JavaScript... Can you please help?

Does django support composite primary key, like combination of 2 fields as primary key without having an extra column named id, i have googled a lot and couldn't find a proper solution to it..
Sanjay Krishnan
Has anyone faced this problem?

since you ask this in django group, then my answer is if you are good with django, then you will be good at python and javascript. that means learning nodejs will be as easy as reading docs.

you can use primary key instead index as fk but i still dont understand what you want to do

@Inchidi so you mean to say that django is equal to learning python + javascript + nodejs
Anonymous
(concept wise)
Sanjay Krishnan

I don't want id as primary key, instead if i have fields A and B then i want to identify objects uniquely by the combination of these 2 fields
inchidi
@Inchidi so you mean to say that django is equal to learning python + javascript + nodejs
not equal, but python is a must, javascript is a must in most case.
learning nodejs is personal choice but will be easier if you already good with django for sure

Anyone has a clue?
inchidi
Kaio
I tried.. but it seems not working.. the paginate_by only paginate the queryset of the listview.. but I'm displaying the results using the FilterQuerySet
Kaio
didn't find a way to paginate the filtering
inchidi
inchidi
pls share your view
Kaio
class CompanyListView(ListView):
model = Company
paginate_by = 9
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['filter'] = CompanyFilter(self.request.GET, queryset=self.get_queryset())
return context
Miguel

inchidi
Kaio
Good!
Kaio
I'm trying
`def get_queryset(self):
return CompanyFilter(self.request.GET, queryset=Company.objects.all()).qs`
inchidi
class CompanyListView(ListView):
model = Company
paginate_by = 9
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['filter'] = CompanyFilter(self.request.GET, queryset=self.get_queryset())
return context
def get_queryset(...):
queryset=super().get_queryset(...)
company_filter =CompanyFilter(self.request.GET, queryset)
return company_filter.qs
inchidi
should be something like this
