Ensure UpperCase on field

[Ari Sobel]

Hi to all,

i want to ensure Upper case on a field,

I've tried the below code:
   function on_before_field_changed(field) { 

           if(field.text && field.field_name=="pedido_base"){ 

            field.text = field.text.toUpperCase()

     } 

 }

  But I've gotten the following msg:

One of the main obstacles with using “on_field_changed” is a infinite loop happening. For example one field changing the field we are expected to “monitor”.

It is this:
function on_before_field_changed(field) {
    if (field.field_name === ' pedido_base' && field.new_value) {
        field.new_value = field.text.toUpperCase();
    }
}

I would suggest to check the Docs Ari:
