Hi,  
I wanna make one dynamic rule engine for that suppose i create one  
rule designation equals Project Leader.

Now my question is that now how i will validate this rule and how i will  
check condition for this in controller.

I can check something like designation.eql?(“Project Leader”) but that  
rule will be in plain English as i said above.

So,please tell me how can i do this.I hope all of you got my  
problem…

Thanks  
Varun
