Usage of model variable instead of name in expressions.

[nikos445]

Is there a way to use "Model" variable instead of "Name" in expressions?

I am trying to do something like this:

• type: enum
  name: choice
  values:

  • x
  • y

• type: expression
  name: x
  model: test
  expression: '{x: "123"}'
  dependencies: x

• type: expression
  name: y
  model: test
  expression: '{x: "456"}'
  dependencies: y

• type: expression
  name: z
  expression: "return 'test.x' "

where x and y is 2 Remote API requests and "z" is a local option after one of requests return a value...

Any ideas?

name: z shall be the same always as it is used by multiple other expressions ...

so this is probably what you want...

for field z :

• I use "ignoreIncomplete" => that ignores unevaluated placeholders and falls back to undefined
• I use the || operator => this is a fallback operator (if the first is undefined, it falls back to the secode)
• Alternatively you can use operator ?? => as || is a true/false operator (empty strings or false booleans will fallback)

Also note I'm using an inline function, I often use this for better visibility :

((x=true,y='mydefault',z='4')=>{ return something using variables x,y,z })( $(var1), $(var2), $(var3) )

The above defines an inline function, with 3 parameters each having a default value in case undefined is passed.
You can then pass your 3 variables in an inline execution. Make sure you use ignoreIncomplete to handle undefined fields.
