Internally, every method in Odoo has access to a dictionary called context that is propagated from every action to the methods involved in delivering that action. The UI also has access to it and can be modified in various ways by setting values in the context. In this recipe, we'll explore some of the applications of this mechanism by toying with the language, default values, and implicit filters.
