I am getting this error File "C:\Python\Python38\lib\site-packages\django\core\handlers\base.py", line 124, in _get_response raise ValueError( ValueError: The view home.views.seller_register didn't return an HttpResponse object.

This is view def seller_register(request): if request.method=='POST': a=SellerRegisterForm(request.POST) if a.is_valid(): email=a.cleaned_data['email'] try: f=SellerRegister.objects.get(email=email) error_message="Email Already Taken" return render(request,'seller_register.html',{'error':error_message,'fm':a}) except: a.save() return redirect('index') else: a=SellerRegisterForm() return render(request,'seller_register.html',{'fm':a})

if a.is_valid(): else for this if

if a.is_valid(): else for this if

There is no else

if a.is_valid(): else for this if

Thanks I add and it resolved

exactly thasts why you are receiving this error because if a.is_valid(): is false then its looking for else but its not their and neither the statement for if method =post

But why it is important to add that bcz I had not added in others but it worked

Thanks I add and it resolved

I tried documentation, import future fail

I tried documentation, import future fail

It does not make sense what u have said Try to share code and errors u have

"from future imports must occur at the beginning of the file"

future

There is double underscore on beginning and end on future.

"from future imports must occur at the beginning of the file"

It's a python error not a Celery one You need to put at the beginning of the file most of times

create category table in db

how would i know?? before creating a website you should clearly define models and create draft of database schema with all entity and relationship tables, after making sure everything is fine, then you have to implement it

the core part of backend application is not just your view functions, the most important part is db part, if your db is well implemented, you will have much less difficulty in your project

X(id, name,brand,size) , Y(X foreign key, ...) . I want to see X.brand in to the Y model) How can i do that.

Use this code: data = models.Foreignkey(X, on_delete = models.CASCADE)

Use this code: data = models.Foreignkey(X, on_delete = models.CASCADE)

It works for me. X is the models class name as you said.

It works for me. X is the models class name as you said.

oh thanks. Sorry for my English. I need to fields of the Model(as X) in to the Y model. For example: X model has this fields= name,color_code. Y model has this field = X(related with ForeignKey) and other fields parameter. But i want to Y model include the color_code in the Admin panel. I hopefully understand me

Do default = None and Null = true do the same thing? No data is to be recorded in the field

Do default = None and Null = true do the same thing? No data is to be recorded in the field

None != Null

X(id, name,brand,size) , Y(X foreign key, ...) . I want to see X.brand in to the Y model) How can i do that.

Inside Y you can access all X fields just using X.brand, X.*, when you define a relationship, the X inside Y is not just a field in ORM, it is a particular instance of X model
