How to get the list of variables used in a Rule

[zakerzadeh]

I have created a Rule object like below

rule = rule_engine.Rule("Name == 'John' and Type== 'Auto'")

How can I get the list of variables used in my rule, ie. I want to get "Name" and "Type".

In my use case, the rules are very dynamic and are red from a file, so they might contain different variables. I need to dynaically be able to understand what variables are used in each rule.

There's a symbols attribute on the context object. Assuming the context isn't shared across multiple rules, you can access it to see the symbols.

Should be something like rule.context.symbols.
