Django cors headers and server error -

i'm trying use django-cors-headers add cors server, when load page receive error on server.

improperlyconfigured: error importing module corsheaders.middleware.corsmiddlewaredjango.middleware.common: "no module named corsmiddlewaredjango.middleware.common" 

i've installed cors-header app using pip:

pip install django-cors-headers 

and settings.py file configured way:

installed_apps = (     'django.contrib.admin',     'django.contrib.auth',     'django.contrib.contenttypes',     'django.contrib.sessions',     'django.contrib.messages',     'django.contrib.staticfiles',     'social.apps.django_app.default',     'corsheaders',     'dashboard', ) middleware_classes = (     'django.contrib.sessions.middleware.sessionmiddleware',     'corsheaders.middleware.corsmiddleware'     'django.middleware.common.commonmiddleware',     'django.middleware.csrf.csrfviewmiddleware',     'django.contrib.auth.middleware.authenticationmiddleware',     'django.contrib.messages.middleware.messagemiddleware',     'django.middleware.clickjacking.xframeoptionsmiddleware', ) cors_origin_allow_all = true 

i'm using python 2.7 version.

you're missing comma after 'corsheaders.middleware.corsmiddleware' in middleware_classes.

add one.

your issue caused fact python concatenating strings 'corsheaders.middleware.corsmiddleware' , 'django.middleware.common.commonmiddleware' , therefore trying import commonmiddleware corsheaders.middleware.corsmiddlewaredjango.middleware.common'.
