Greetings,
I have created a couple widgets: ItemFields and MenuFields. Both
extend WidgetsList. I use both in a TableForm. The ItemFields are
used to create an Item, while the MenuFields are used to create a
Menu. In my MenuFields class, I select all the Items
(model.Item.select()) and use the results to populate a CheckBoxList.
The problem I have is after adding a new Item, it does not show in the
TableForm made from the MenuFields. How do I ensure the CheckBoxList
in my MenuFields is always up to date.
Thanks in advance. My code follows:
class ItemFields(widgets.WidgetsList):
"""Form fields for creating an Item."""
name = widgets.TextField(validator=validators.NotEmpty())
active = widgets.CheckBox(attrs=dict(checked=True),
help_text='If unchecked, it is unavailable to new menus.')
class MenuFields(widgets.WidgetsList):
"""Form fields for creating a Menu."""
item_list = []
all_items = model.Item.select(model.Item.q.active == True,
orderBy='name')
for item in list(all_items):
item_list.append((item.id, item.name))
date = widgets.CalendarDatePicker("date")
items = widgets.CheckBoxList(validator=validators.Int(),
options=item_list)
item_form = widgets.TableForm(
fields=ItemFields(), action='save', submit_text='Add Item')
menu_form = widgets.TableForm(
fields=MenuFields(), action='save', submit_text='Add Menu')
class Menu(controllers.Controller):
@expose(template='.templates.add')
def add(self, tg_errors=None):
"""Show the Menu form."""
if tg_errors:
flash('There was a problem with the form!')
return dict(form=menu_form)
