I am using IntelliJ IDEA 13 Ultimate edition with its Python plugin. I opened an existing folder containing a Django project (which I had created using Vim) as an IntelliJ project and enabled the Django facet manually on it. However, my HTML files are still being treated as plain HTML files - Django template tags and syntax aren't recognized. I recall that Django templates were automagically recognized by IntelliJ in an earlier project, but can't reproduce it now.
How can I get IntelliJ to recognize my template files as Django templates, please?
