Sorry if I'm not explaining this well. The default widget for a list:string
field is a vertically stacked list of inputs, one per value. There is a
little + at right that allows me to add more inputs to the list
dynamically.
In a SQLFORM, when I set keepvalues=True the values are preserved in the
form fields after form submission. But only one of the inputs from the
list:string widget is left, holding just the last string value submitted
for that field. In other words, the form doesn't remember the additional
inputs I added to the widget (by clicking +) before submission, and it
forgets the submitted values from those additional inputs as well.
I've experienced this on many forms, so I don't think it's my code. In the
case that brought this up for me again, I'm creating a SQLFORM.factory with
the fields defined in the controller. (You can see that I've got some for
loops to simplify the creation and processing of a large number of fields,
but otherwise it's straightforward.) The problem appears with the widgets
for any of the list:string fields:
message = ''
output = ''
flds = [Field('label_template', 'string'),
Field('words', 'list:string'),
Field('aligned', 'boolean'),
Field('avoid', 'list:string'),
Field('testing', 'boolean')]
for n in ['one', 'two', 'three', 'four', 'five']:
fbs = [Field('{}_prompt_template'.format(n), 'list:string'),
Field('{}_response_template'.format(n), 'list:string'),
Field('{}_readable_template'.format(n), 'list:string'),
Field('{}_tags'.format(n), 'list:reference tags',
requires=IS_IN_DB(db, 'tags.id', '%(tag)s',
multiple=True)),
Field('{}_tags_secondary'.format(n), 'list:reference
tags',
requires=IS_IN_DB(db, 'tags.id', '%(tag)s',
multiple=True)),
Field('{}_tags_ahead'.format(n), 'list:reference tags',
requires=IS_IN_DB(db, 'tags.id', '%(tag)s',
multiple=True)),
Field('{}_npcs'.format(n), 'list:reference npcs',
requires=IS_IN_DB(db, 'npcs.id', '%(name)s',
multiple=True)),
Field('{}_locations'.format(n), 'list:reference
locations',
requires=IS_IN_DB(db, 'locations.id',
'%(map_location)s',
multiple=True)),
Field('{}_instructions'.format(n),
'list:reference step_instructions',
requires=IS_IN_DB(db, 'step_instructions.id',
'%(instruction_label)s',
multiple=True)),
Field('{}_hints'.format(n), 'list:reference step_hints',
requires=IS_IN_DB(db, 'step_hints.id',
'%(hint_label)s',
multiple=True)),
Field('{}_step_type'.format(n), 'list:reference
step_types',
requires=IS_IN_DB(db, 'step_types.id',
'%(step_type)s',
multiple=True)),
Field('{}_image_template'.format(n), 'string')]
flds.extend(fbs)
form = SQLFORM.factory(*flds)
if form.process(keepvalues=True).accepted:
vv = request.vars
stepsdata = []
for n in ['one', 'two', 'three', 'four', 'five']:
nkeys = [k for k in vv.keys() if re.match('{}.*'.format(n),
k)]
filledfields = [k for k in nkeys if vv[k] not in ['', None]]
if filledfields:
ndict = {k: vv[k] for k in nkeys}
stepsdata.append(ndict)
if isinstance(vv['words'], list):
wordlists = [w.split('|') for w in vv['words']]
else:
wordlists = [vv['words'].split('|')]
paths = self.make_path(wordlists,
label_template=vv.label_template,
stepsdata=stepsdata,
testing=vv.testing,
avoid=vv.avoid,
aligned=vv.aligned
)
message, output = self.make_output(paths)
elif form.errors:
message = BEAUTIFY(form.errors)
