Here is a bit of syntactic sugar I use for creating fields with less
typing. And better consistency, of course -- there always has to be a good
reason for my lazy keyboard-saving shortcuts!
I have a number of fields which are for specific data types, such as phone
numbers. I gather the "common" parts of the Field definition into a
dictionary:
phone_fld = {'requires':IS_EMPTY_OR(IS_PHONE()),
'widget':lambda fld,val: SQLFORM.widgets.string.widget(fld,val,
_type='tel',_class='form-control')}
When defining the field in a table, I invoke the dictionary at the end of
the Field definition:
Field("homephone","string",length=20,label=T("Home phone"),**phone_fld),
Field("workphone","string",length=20,label=T("Work phone"),**phone_fld),
Field("cellphone","string",length=20,label=T("Cell phone"),**phone_fld),
Now the field is created exactly as I want. I keep a list of these
"helpers" in a module which I can call out when creating tables. It really
saves the typing and allow me to control how my fields are rendered on one
place instead of scattered among all the tables.
