[Zope3-Users] zc.table FieldColumn question
Does anyone have a simple example of how FieldColumn
is used?
I'm quite sure I'm missing a very serious step here,
but have been unable to figure out how to trigger
the update method. Any help at all would be
appreciated.
I've tried the following, the request values show on
screen but fail to update the object.
class MovieColumnSubmit(fieldcolumn.SubmitColumn):
def getId(self, item, formatter):
return fieldcolumn.toSafe(item.__name__)
class MovieColumn(fieldcolumn.FieldColumn):
def getId(self, item, formatter):
return fieldcolumn.toSafe(item.__name__)
class TableView(BrowserPage):
columns = (
MovieColumn( IMovieTime['brief']),
MovieColumn( IMovieTime['times']),
MovieColumnSubmit(apply, MYFORM),
)
def __call__(self):
items = [value for name, value in
self.context.items()]
formatter = table.Formatter(
self.context, self.request, items,
('brief', 'times', 'MYFORM'),
columns=self.columns,
prefix=tableview)
return htmlhead/headbodyform
action=./@@TableView.html%s/form/body/html
% formatter()

Ok, so the following works, but if someone with more
knowledge could comment on this I'd appreciate it.
class MovieColumnSubmit(fieldcolumn.SubmitColumn):
def getId(self, item, formatter):
return fieldcolumn.toSafe(item.__name__)
def update(self, items, data, formatter):
pass
class MovieColumn(fieldcolumn.FieldColumn):
def getId(self, item, formatter):
return fieldcolumn.toSafe(item.__name__)
def update(self, items, data, formatter):
changed = False
for item in items:
id = self.getId(item, formatter)
v = data.get(id, self)
if v is not self and self.get(item,
formatter) != v:
self.set(item, v, formatter)
changed = True
if changed:
self.setAnnotation('changed', changed,
formatter)
return changed
class TableView(BrowserPage):
Browser Page
columns = (
MovieColumn( IMovieTime['brief']),
MovieColumn( IMovieTime['times']),
MovieColumnSubmit(apply, MYFORM),
)
def __call__(self):
items = [value for name, value in
self.context.items()]
formatter = table.Formatter(
self.context, self.request, items,
('brief', 'times', 'MYFORM'),
columns=self.columns,
prefix=tableview)
columns = self.columns
for index, value in enumerate(columns):
data = columns[index].input(items,
formatter)
columns[index].update(items, data,
formatter)
return htmlhead/headbodyform
action=./@@TableView.html%s/form/body/html
% formatter()

We have two separate stages (and methods) in our views, update and render. In our views, we *explicitly* call the field columns' input, and then call their update during the update stage. Sometimes we only call input/update if some other event happens, like an Apply button being clicked on the page. Then we render.
