Is there a preferred naming convention for creating a Django app consisting of more than one word? For instance, which of the following is preferred?
my_
App directory names must be a valid Python package name. This means that option 2 is completely inadmissible as a package name, although it can still be used for other purposes, such as documentation. In the end it comes down to personal style. If you prefer option 3 then use it.
They must be valid package names. That rules out 2 ("import my-django-app" would be a syntax error). PEP 8 says:
Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.
So, 1 and 3 are both valid, but 3 would be the recommended approach.
My votes for 1 and 3, but you can check several popular apps: http://www.django-cms.org/ http://geodjango.org/
some good examples
in simple terms, app_name
should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. also should have a short name and it can be a plural and singular name
