Django Version

Django==3.2.8
pytz==2021.3

JavaScript
 
Django==3.2.8
pytz==2021.3
​

every time i refresh it shows David D the previous value of name not the new one i have to restart the server to show the new value

Also when changing the HTML code it detect the change and just refreshing the page is sufficient(no need to restart the server) for python it is another story it does not detect any change (need to restart the server to detect the change)

i also tried making different projects

update: I tried another Django version Django==2.1.5 and it works fine I really do not know the cause of the problem but changing the version seems to work

update 2: I have tested the 3.2.8 version of django on another PC and it is working fine so i do not know where is the problem

Answer

I just found the reason for this problem in my settings.py file

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, "templates")],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

JavaScript
 
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, "templates")],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]
​

I was doing

'DIRS': [BASE_DIR, "templates"]

JavaScript
 
'DIRS': [BASE_DIR, "templates"]
​

Now after using

'DIRS': [os.path.join(BASE_DIR, "templates")]

JavaScript
 
'DIRS': [os.path.join(BASE_DIR, "templates")]
​

It is working fine Django version == 3.2.8 in this version do not forget to import os and for the other versions I used os.path.join so that explains why it was working, beside if you are doing the urls.py files well it will work even without including the templates in DIR list
