How do I create a new module in django and register the classes in that module-CodePudding

I want to create a new module and set of middleware classes in my app. I created a subfolder "middleware" and put my python classes there in separate files. But when I try to access them it says not defined.

For the following to work where do I place my 'CustomerMiddleware' class and what else do I need to do?

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'dose.middleware.CustomMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

CodePudding user response：

Place your middleware at the end of your middleware section

The exact reference will depend on where the files live in your directory structure, relative to your projectfolder. I keep mine in the same folder as my base URLs.py and asgi/wsgi files, so mine looks like the below

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'dose.middleware.CustomMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'projectname.middleware_filename.middlewareclass1',
'projectname.middleware_filename.middlewareclass2',
]

I was trying to find a way to subclass a core Django class so I could change its behavior. I found out how to do it, but along the way I discovered the Django Middleware that could intercept requests and responses anywhere in the application regardless of the app. A CustomMiddleware was the key and with that I can do anything I want to do either before or after a request is handled by the model.

Here is the Middleware documentation

Enjoy.
