I have a form where I want the user to be able to specify a custom formula and then have this formula calculated.
I am using the npm module expressions-parser/func to achieve this in a Blaze helper like this:
Template.calculated.helpers({
value(){
const mkFunc = require('expression-parser/func');
console.log(mkFunc.express(this.rowArgs.row.formula));
const fn = mkFunc(this.rowArgs.row.formula);
let rv = this.rowArgs.formData.get();
console.log(rv, fn, fn(rv));
const value = fn(rv);
return round(value, 3);
}
});
This works really well for even complex functions when I test this on local development.
My debug console messages return on localhost for an input formula that is simply Number
symbols["Number"]
Object {Number: "123"}
function anonymous(symbols/*``*/) {
symbols = symbols || {}; // 80
return (symbols["Number"]);
"123"
Doing the same once deployed onto Galaxy I get instead:
symbols["Number"]
Object {Number: "123"}
function anonymous(symbols/*``*/) {}
undefined
I have no idea how to even start debugging this.
