Forcing a default unit for Properties
Closed, DeclinedPublic


Author: dan.bolser

If I have a property of type 'size' that can accept mm, cm, m, km, etc. and these units correspond to 0.01, 0.1, 1, 1000, respectively. If the user then enters a number without specifying the unit, is there a way to have SMW automatically assume that value corresponds to the unit for which '1' is assigned (in this case, m)?

Answer: No!

The unit for which the conversion fact of 1 is assigned, the "Standard Unit" or "main unit", *should be* the default unit used when none is specified by the user.

Not specifying a unit causes the property to 'break':

The type "Time":

  • [[Corresponds to::1 h, hour, hours]]
  • [[Corresponds to::3600 s, second, seconds]]

The property "Has duration":

  • [[Has type::Time]]

The page "Sandbox":

  • [[Has duration::3]]
  • [[Has duration::2 hours]]
  • [[Has duration::10 seconds]]

{{#show: {{PAGENAME}} | ? Has duration # s }}

The show query does not return the value of 3 hours in seconds...
