Hi All,
I wanna to do something like as:
1. Use will type plain English in text box like designation equals PM or
designation = PM.
2.Then i have to save this rule in DB and i have to made some function
to verify this rule.
3. My problem is that how to make if condition for following rule
dynamically.Cos in ROR i can say designation == 'PM'then fine but how i
will check that designation equals PM.
4.Means i have to make condition from plain english dynamically.
I would recommend that you create a DSL for your users. You can setup a mapping that abstracts away your domain specific names and allows for various types of rule creation. You need to guard/filter against code injection if you are eval-ing the rules directly.
