i want to perform this function between two liists, what function?

[<CartItem: Royal Watches 2>, <CartItem: Royal Watches 2>] i want this from it ['Royal Watches 2','Royal Watches 2',] how can i do this

[<CartItem: Royal Watches 2>, <CartItem: Royal Watches 2>] i want this from it ['Royal Watches 2','Royal Watches 2',] how can i do this

You need to convert list to model objects?

sorry from this <QuerySet [<CartItem: Royal Watches 2>, <CartItem: Royal Watches 2>]> bro i am beginner so i don't know that much

sorry from this <QuerySet [<CartItem: Royal Watches 2>, <CartItem: Royal Watches 2>]> bro i am beginner so i don't know that much

If you are begginer go learn django, I don't know what you want to get from queryset, learn how to work with it, and you will understand why you dont need list for this

Queryset is already a list(simplified)

I still don't understand what you want, but if you need to 'connect' two queryests into one you can do that with: queryset1 |= queryset2

i don't want to connect them i am working on ecommerce website in which i want to merge the two carts 1 cart = local withou login 2 cart = online on database

i don't want to connect them i am working on ecommerce website in which i want to merge the two carts 1 cart = local withou login 2 cart = online on database

So it fully depends on how your cart, and database made

i don't want to connect them i am working on ecommerce website in which i want to merge the two carts 1 cart = local withou login 2 cart = online on database

What is the connection b/n models?

Watch some videos on YouTube at least to get familiar with django. I don't sometimes understand you people are jumping into building e-commerce without getting familiar. Start from basics, please.

bro didn't jumped i purchased the udemy cource and teacher directly started this his code is working mine not can you suggest any another course i am going to cancel that one

Hi, how can I add some extra key/values to cleaned_data ? I mean, I have a form with x and y fields, but I want a "z" in my cleaned data which is the result of x + y

Don't know what to advise you, I never bought courses, there are tons of stuff on YouTube. Just start from basics, blog with comments, auth, tags, categories or even a todo-app.

i will but here is final code that i need try: if user is not None: cart = Cart.objects.get(cart_id = _cart_id(request)) cart_item = CartItem.objects.filter(cart=cart) prodcut_vari = cart_item.values_list('product__name', flat=True) prodcut_vari = list(prodcut_vari) print(prodcut_vari) cart_item = CartItem.objects.filter(user=user) ex_vart = cart_item.values_list('product__name', flat=True) ex_vart = list(ex_vart) id = [] for i in cart_item: id.append(i.id) for pr in prodcut_vari: if pr in ex_vart: index = ex_vart.index(pr) item_id = id[index] item = CartItem.objects.get(id=item_id) item.quantity +=1 item.user = user item.save() else: cart_item = CartItem.objects.filter(cart =cart) for item in cart_item: item.user = user item.save() else: pass auth.login(request,user) return redirect('home')

thanks a lot to everyone now i will start from youtube

Hi, how can I add some extra key/values to cleaned_data ? I mean, I have a form with x and y fields, but I want a "z" in my cleaned data which is the result of x + y

just use them like z = form.cleaned_data['y'] + form.cleaned_data['x'] that there is no advetage appending extra key/values to it, I guess.

just use them like z = form.cleaned_data['y'] + form.cleaned_data['x'] that there is no advetage appending extra key/values to it, I guess.

because data is already cleaned

Hi, how can I add some extra key/values to cleaned_data ? I mean, I have a form with x and y fields, but I want a "z" in my cleaned data which is the result of x + y

Try passing commit=False to form.save() ,then adding extra field and then saving form

just use them like z = form.cleaned_data['y'] + form.cleaned_data['x'] that there is no advetage appending extra key/values to it, I guess.

I made it simple to x,y,z. It's not this simple, actually. So I need it in cleaned_data in my case

Try passing commit=False to form.save() ,then adding extra field and then saving form

It's not a ModelForm. It's Form

I tried to declear a new field named z and then in clean_z() I did return x + y but unfortunately it won't show up in cleaned_data

I made it simple to x,y,z. It's not this simple, actually. So I need it in cleaned_data in my case

do you want to save the data in that fields ?

do you want to save the data in that fields ?

to your model

Yes I want to save something like x + y in z

to your model

No, not model

No, not model

what else ? or they should be rendered in views ?

what else ? or they should be rendered in views ?

Yes it's just a regular form which will be rendered in templates

Yes it's just a regular form which will be rendered in templates

cleaned_data is dictionary , so maybe you can use update method like that s = {} s.update({'a' : 1}) # adding 'a' key with value of 1 then you can use s['a'] like that it will return -> 1

why u want to save ?

I want to add the z to cleaned_data using the form class itself. I mean like: class MyForm(Form): x = ... y = ... z = ... def clean_z(self): return self.data.get("x") + self.data.get("y") THEN IN VIEWS: form = MyForm(request.POST) form.is_valid() print(form.cleaned_data) And I expect this result: {"x":1, "y":2, "z":3} But it shows: {"x":1, "y":2} ( I did not rendered z in my template )

This is my url in postman what should be the url for urls.py in http://127.0.0.1:8000/api/v1/division/list/?school_id=d7a72306-046b-40ff-9d01-d0252507e4c7

dont put z as field in form , simply get z in your view diectly through request.POST['x']+request.POST['Y']

I tried this but not working. re_path(r'^api/v1/division/list/(?P<school_id>[\w\d-]+)/$', division_view.get, name='list'),

need instant help.

dont put z as field in form , simply get z in your view diectly through request.POST['x']+request.POST['Y']

Need validations on z. x + y is simplified function, it's not the actual thing I want

def clean_additional_costs(self): keys = self.data.getlist('additional_costs_key') values = self.data.getlist('additional_costs_value') cleaned_keys = list(filter(lambda x: x not in [None, '', ' '], keys)) cleaned_values = list(filter(lambda x: x not in [None, '', ' '], values)) if not len(cleaned_keys) == len(cleaned_values): raise forms.ValidationError( "invalid len!", code="invalid_len", ) return dict(zip(cleaned_keys, cleaned_values))

clean_additional_costs is clean_z

clean_additional_costs is clean_z

My guess is that you can override form's clean() method, thus your fields gonna be validated and you gonna have access to form's errors, you would be able to use add_error() method to your z field.

Yes i guess it's possible but I coudn't find out how to add z to it and also run clean_z

Seems clean_z only runs when I render it in template and there is something like z_htmlName in my POST data

I tried this but not working. re_path(r'^api/v1/division/list/(?P<school_id>[\w\d-]+)/$', division_view.get, name='list'),

Maybe use a newer way to define url patterns with converters like <uuid:school_id>

Yes i guess it's possible but I coudn't find out how to add z to it and also run clean_z

Why do you need to run clean_z if z is dependent on other fields, might be a stupid question though. And yeah, why not just use clean_z() method. Or z.validate(). Data is cleaned when validation begins, so you would have access to cleaned_data. Read https://docs.djangoproject.com/en/3.2/ref/forms/validation/

raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: WSGI application '(my_app_name).wsgi.application' could not be loaded; Error importing module. Can anyone help for this error?

Data is cleaned when validation begins, so you would have access to cleaned_data. Read https://docs.djangoproject.com/en/3.2/ref/forms/validation/

z needs to be validated to check if len(x) and len(y) are equal after filtering None and empty input values, then return them as a zip, so each x key have a y value, otherwise raise an error in form The problem is clean_z will not run at all

x and y are a fieldset for additional costs, they are connected to each other on template x is title and y is price User can clone() [ in js ] them and add more additional costs So if user send 10 x and y they all have same names and ids Then I need to bind all that additinal costs to each other, so any title have a price I want to have access to these as a dict in z field

is_valid() should trigger any validations even custom, but you need to tell your form fields to use specific validation. Sorry if I am not helpfull

Validation is decleared in clean_z, please reffer to the code I've sent But it won't run it, like z field doesn't exists at all

Anyone who acknowledges the heroku deployment for django project pls dm me i am stuck in and i need help

You can validate in your view and add error in form from there also

Yeah it's a way but I wanted to use form :( I guess I have to validate in views anyway

Yeah it's a way but I wanted to use form :( I guess I have to validate in views anyway

Yeah ultimately u gonna push error in form only, that can be done through view also

Don't mess a framework itself and what you can do with it. The docs describe at least 90% of what you need to know about django. On the other hand - creation of applications is a matter of oo-decomposition and architecture.

Does documentary teach this?

If you ask such a question, I would advise you to recheck your knowledge of OOP for it seems you know not much than "classes have methods and can go inheritance"
