Hi...
Continuing to refactor several forms I isolated some common fields and I found
out that I can "reuse" them inside a new list. Something like this:
class CommonWidget(widgets.WidgetsList):
my_common_widget = widgets.SomeField(...)
class UseCommonWidget(widgets.WidgetsList):
one_widget = widgets.OneField(...)
another_widget = widgets.AnotherField(...)
common = CommonWidget()[0]
class UseCommonWidgetAsWell(widgets.WidgetsList):
other_widget = widgets.OtherField(...)
yet_another_widget = widgets.YetAnotherField(...)
common = CommonWidget()[0]
after_common_widget = widgets.AfterCommonField(...)
And this works except for the fact that "CommonWidget" doesn't respect the
ordering while displaying a form that uses any of UseCommonWidget or
UseCommonWidgetAsWell. They are placed as the first widget while rendering
the template. It doesn't matter -- on my tests -- what type of widget is
SomeField (TextField, CheckBox, SingleSelectField) this always happens.
If I have this "CommonWidget" as the last one there's no problem in
concatenating it while creating the form and in fact I do that for several
forms. The problem is when "CommonWidget" should be in the middle of the
form what would require me to split the form in two so that I could
concatenate them -- breaking the "logic" flow sometimes. Or when there are
three, four different common fields (it is not feasible to break a form in 5
or 6 parts just because of that).
Why am I worried with that? Because it requires one to either duplicate code
and makes maintenance more problematic and also because this is not the
behavior we have with lists, where order is preserved:
>>> some_list = [1]
>>> another_list = [2, 3, some_list[0], 4]
>>> another_list
[2, 3, 1, 4]
>>>
So, is there any "magic" going on here? Is it intentional? If not, is it
possible to fix this so that we have a consistent behavior with lists and
widgets lists?
(Making it clear, these aren't HiddenFields ;-))
