Hi,
I have created an application in rails but I am having problem in
computing taxable income from the supplied datas in the database .
How can I connect the database to the controller so that I can access
basic,hra, medical allowance etc from database to calculate it in
controller and display the output in view.
code that I have written in controller
class HomeController < ApplicationController
def index
@taxableincome= basic+hra
end
end
code that I have written in view
<h1>tax calculation</h1>
<br>
the taxableincome is = <%= @taxableincome %>
<%= link_to "old members", posts_path %> <%=link_to"enter new
details",new_post_path %>
If I want to make another link "taxableincome" whick will show me the
result of taxableincome as I click it how can I do it ?
since, I am having these problems I am unable to proceed.
please guide me to fix these problems.
Thankyou,
Regards,
Chandana Boral
