Hi All,
What's the correct way to limit the number of entries in a
SequenceSchema node?
The requirements is something like "each job must have at least one
requirement line, but no more than 5"
Not sure if you mean UI or validation, but:
- UI wise: use the min_length and/or max_length parameters to
SequenceWidget. See
http://deformdemo.repoze.org/sequence_of_constrained_len/
Validation-wise, put a validator on the schema node, see the same
example.
I meant both, so thanks for both answers :-)
I'm also keen to know if anyone has done a widget which uses a
<textarea> to produce a sequence of strings, rather than the JS "add one
as a time" approach?
See http://deformdemo.repoze.org/textareacsv/
If I just wanted to have something akin to the old Zope "lines" property
type, would the following do the trick?
class Lines(colander.SequenceSchema):
line = colander.SchemaNode(colander.String())
class Schema(colander.Schema):
lines = Lines(
widget = TextAreaCSVWidget(rows=5, cols=1)
)
If not, what would? :-)
Also, when would you use:
http://deformdemo.repoze.org/widget_adapter/
...instead of TextAreaCSVWidget?
cheers,
Chris
