Hi,

In Odoo, the qcontext variable is a dictionary that allows you to pass additional context data to a template from a controller method. It stands for "quick context" and is used to provide specific data or variables to the template rendering process.

The qcontext variable can be used to define variables that are not part of the default context, allowing you to customize the behavior or appearance of a template. It is commonly used to pass additional information to the template that is derived from the controller method.

Here's an example of how to use qcontext in Odoo:

qcontext = {
'custom_variable': custom_variable,
}

return http.request.render('my_module.my_template', qcontext)

Thanks

Hi,

Q Context helps to get the values returned from the original controller and to modify the value. The Controllers are the frontend modules and they can be integrated with backend modules which will help to render the requests to the web_browser.
