How to do dynamic maxValue Expressions in AnsibleForms

[MarcosLealSierra]

Hello,

I’m currently working with AnsibleForms and have encountered a scenario where a dynamic validation would be extremely helpful. In my form, I need to ensure that a number field does not exceed a limit that is dynamically calculated based on another field’s value. However, it seems that the maxValue property currently only accepts a literal integer and does not support dynamic expressions.

Would it be possible to consider adding support for dynamic validations or custom validators in future versions of AnsibleForms? This feature would greatly assist in scenarios where validation needs to depend on other field values.

Thank you very much for all the hard work on this project. I truly appreciate the effort that has gone into developing AnsibleForms, and I look forward to your thoughts on this suggestion.

Best regards,

Marcos

just make a local expression field that results in a boolean and use the validIf or validIfNot validator with custom description.

See example : #268

fields:
  - name: mymax
    type: number
    default: 5
  - name: ishigher
    type: expression
    runLocal: true
    expression: ((x,y)=>{ return y>x })($(mymax),$(myvalue))
  - name: myvalue
    type: number
    validIfNot:
      field: ishigher
      description: that's too high.
    default: 3
