I have seen in presentations and posts that by changing the "odoo" part of the url to "json" I can then get a json response:
Example:
/odoo/project/5/tasks
/json/project/5/tasks
This works on Runbot and on demo.odoo.com but not my production instance.
I would like to activate the /json/ view on URL change on my database.
What do I have to do to enable it?
