I am building a TODO-list type application while studying web2py. For each
task, I would like to set a priority. Having integer values for priority
makes it easier to query something like db(db.task.priority > 1).select().
Because there will be only a few of them, I would just create some
constants for them (rather than creating a priority table). Also I would
like to show descriptive text rather than numbers on drop-down list.
My model looks something like this.
class Priority:
LOW, MEDIUM, HIGH, URGENT = range(1, 5)
set = {LOW: 'Low', MEDIUM: 'Medium', HIGH: 'High', URGENT: 'Urgent'}
db.define_table('task', Field('name'), Field('priority',
requires=IS_IN_SET(Priority.set, zero='Select on')))
Everything works well, except that on the view it is kind of ugly to
display the priority text instead of numbers. The way I am doing is
<td>Priority: </td> <td>{{= Priority.set[ int( task.priority ) ] }}</td>
I envision that it would become uglier and harder to understand, where I
start adding more fields. I wonder if there's a better way to do this? I am
also open to go about other ways than doing a constant based approach.
Thanks a lot for your help! - Dan
