This page contains some advice about errors and problems commonly encountered during the development of Cookiecutter Django applications.

  1. project_slug must be a valid Python module name or you will have issues on imports.

  2. jinja2.exceptions.TemplateSyntaxError: Encountered unknown tag 'now'.: please upgrade your cookiecutter version to >= 1.4 (see #528)

  3. Internal server error on user registration: make sure you have configured the mail backend (e.g. Mailgun) by adding the API key and sender domain

  4. New apps not getting created in project root: This is the expected behavior, because cookiecutter-django does not change the way that django startapp works, you’ll have to fix this manually (see #1725)

  5. If your email server used to send email isn’t configured properly (Mailgun by default), attempting to send an email will cause an Internal Server Error.

    By default, django-allauth is setup to have emails verifications mandatory, which means it’ll send a verification email when an unverified user tries to log-in or when someone tries to sign-up.

    This may happen just after you’ve setup your Mailgun account, which is running in a sandbox subdomain by default. Either add your email to the list of authorized recipients or verify your domain.
