How to Resolve the \"TypeError: View Must Be Callable\" Error in Django 1.10?

TypeError: View Must Be Callable in Django 1.10

Overview:

Upon upgrading to Django 1.10, users may encounter an error stating, "view must be a callable or a list/tuple in the case of include()." This error occurs due to changes in how Django handles view specifications in URL patterns.

Cause:

Starting with Django 1.10, specifying views as strings ('myapp.views.home') is no longer supported. Django now requires view callables to be explicitly imported and included in URL patterns.

Solution:

1. Import and Specify View Callables:

Modify the URL patterns to include imported view callables. If the patterns lack names, consider adding them to ensure correct URL reversing.

<code class="python">from django.contrib.auth.views import login
from myapp.views import home, contact

urlpatterns = [
    url(r'^$', home, name='home'),
    url(r'^contact/$', contact, name='contact'),
    url(r'^login/$', login, name='login'),
]</code>

2. Import Views Module:

For projects with numerous views, importing each view individually can become cumbersome. Alternatively, consider importing the entire views module from the app.

<code class="python">from django.contrib.auth import views as auth_views
from myapp import views as myapp_views

urlpatterns = [
    url(r'^$', myapp_views.home, name='home'),
    url(r'^contact/$', myapp_views.contact, name='contact'),
    url(r'^login/$', auth_views.login, name='login'),
]</code>

Using Alias:

Note the use of as statements (e.g., as myapp_views) to import multiple views modules without name clashes.

Additional Information:

• For a detailed explanation of URL dispatchers in Django, refer to the official documentation.
• Ensure that the app's views module is correctly named and imported in the settings file (e.g., INSTALLED_APPS).
• If the error persists despite the above solutions, check for any typos or syntax errors in the URL patterns.
