Description

the TemplateResponseView class based view should return kwargs as a dict when calling get_context_data (same as all the other class based views), however it returns the kwargs as {'params': kwargs} therefore they are extra context is namespaced (e.g. {{ params.extra_data }} rather than {{ extra_data }} as documented.

TemplateView behaves according to the documentation. params is intended to contain the parameters captured in the URL.

See https://docs.djangoproject.com/en/dev/ref/class-based-views/#django.views.generic.base.TemplateView

This behaviour seems rather undesirable. The TemplateView is meant to be the quickest and easiest way of rendering a template. Why does it encapsulate the kwargs inside a redundant single-element dictionary? Having to change the templates to include params feels totally wrong.

Is there an alternative class-based view that doesn't require the use of 'params'?

The params dictionary isn't redundant at all -- it's a namespace. The parameters passed in to the view aren't the only context variables that the template can render. Consider the case where the arguments passed in part of the URL pattern overlap with context variables created by the view.
