Hi,
I was playing with tw_samples and have a question about "repetitions"
parameter of FormFieldRepeater. From js_forms.py:
# We wrap the address fieldset with a FormFieldRepeater to
handle
# repetitions. This can be done with *any* FormField.
address = FormFieldRepeater(
widget = AddressFieldset(),
repetitions = 2,
max_repetitions = 5
)
When the form is displayed, address fieldset is repeated twice. But if
I assign three addresses to a person person.addresses =
[dict(street='street1), dict(street='street1), dict(street='street1')]
only the first two are displayed. I thought the widget will
authomagically adjust the number of address fieldsets to the number of
available addresses, with the maximum of 5. Am I wrong?
You'd have to pass a repetitions kw. arg to display to change that
dynamically.
form.display(value, **{'.address':{'repetitions':3}})
However, I'm not very happy with the Repeaters implementation... the
max_repetitions parameter shouldn't even exist and it's true that it
should be a little smarter and adjust itself to the length of available
data...
Currently it creates all repeated fields statically (that's the reason for
max_repetitions)... I'm sure something can be done so this happens
dynamically and repeated widgets are created on-demand (lowering memory
footprint in exchange for slighty higher execution time). I hope to have
something done regarding this before the first alpha in a couple of weeks.
