[FunFormKit-discuss] Repeating Field defaults

[Luke O. <lu...@me...>]

Hey all -

We weren't able to figure out how to set the defaults for a
repeating field, from the existing code it would only take
a single common default.

Here's patched code to Field.py (around line 212, html()) to
allow optionally passing a list of default values for each
repeated field. Defaults for the field either can be
old-style single value, or a list that must have the same
number of elements as repetitions.

Enjoy,

- Luke

if options.get('repeat') and options['repeat'] > 1:
    assert self._repeatable, "You must indicate a field is
repeatable when it is defined"
    out = [html.input(type="hidden",
        name=suffixMap(".repetitions",nameMap)(self.name()),
        value=options['repeat'])]
    if type(defaultValue) is not ListType:
        # build list of defaults...
        #this might be considered list-comp abuse.
        defaultValues = \
          [defaultValue for x in range(options['repeat']) ]
    else:
        assert len(defaultValue) == options['repeat']
        defaultValues = defaultValue
    for i in range(options['repeat']):
        nm = suffixMap(".%i" % i, nameMap)
        out.append(self.htWidget(defaultValue[i], options,
nameMap=nm))
    return out
