I have made three scaffold generated controllers in my project by following three commands ruby script/generate scaffold amain a:integer ruby script/generate scaffold bmain b:integer ruby script/generate scaffold cmain c:integer I want to take three different inputs( a,b,c) on three different pages and then on the third page once a user clicks the button "Calculate" a value based on following equation has to be generated. value = a + b*x1 + c*x2 here, x1 is set on the page where input "a" is set and x2 is set on the page where input "b" is set x1 and x2 are virtual attributes and hence do not exist in any of the data models. Value of these coefficients is not constant and in fact depends on several dynamic factor such as the date and time when a/b was set. I want to know how to pass on the values of "x1" and "x2" from one controller to another. These attributes are not the part of model of "a" or model of "b". I can not keep them in models. Thanks vipin

You can always pass the values as hidden fields... your data isn't going directly from controller to controller. There are views in between, so you need a way to ship the data via the views. If you don't want to see the values on the pages, you can use hidden fields to pass along the data.

Then in this case, will the values be accessed through param table. Can you please give a small example or some pointer to study about this topic. if possible vipin
