While the two solutions provided by the other members may get you access to all the variables in a template I thought there had to be an easier way (thanks for your responses, BTW).
Here is a simple way to find all the variables passed to the template.
- Introduce an error into the template you want to examine. Adding a non-existent tag works.
- Ensure that debugging is ON.
- Browse to the page that loads the template. (your site must be running via runserver or some other means).
The debugging output for the template contains a section called "TraceBack". Find the traceback for your view (second entry from the top in my case) and click on "Local vars". And it's all there.
