Synchron user-request without reloading the site or the controller

Rails

Hello,

I have a controller which gets some data from a user (through a form)
and the it compute the user data and get an result. Depends on the
result I want to make a request (for example: a simple popup) and the
user type into the popup simple data (some numerary) and then the
request return the value back to the controller and the controller can
continue computing with the new data (numerary) and generate the end
result. At the end the view will be generated with access to the end
result.

Is this possible to implement an user requst while the controller is
computing and before the view will generated?

Thanks

Not as such, but the functionality you envision is certainly possible.
Basically, it works like this: the controller determines (or asks the
model to determine) if additional input is needed from the user. If so,
it renders one view template; if not, it renders another.

The point is that (barring client-side JavaScript) no rendering is
possible without involving the view. Nor should it be.

Thanks

Not really - that’s just not how web apps wortk in general.
