I'll respond with a question (don't ya hate that?) To what end is the config format changing? In scenarios where you're only running one TG app in a server, the config file doesn't need to change, right? So, where your question is going likely has more to do with the scenario where you want to run multiple apps within one server. Given that, backwards compatibility (probably with a deprecation warning) can be maintained for people who are only running one app within a server. Then it just becomes the simple matter of what config file format to use for composing multiple apps together into a site, which I will leave as an exercise for the reader. :) Kevin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears Trunk group.

[TurboGears] Re: Reloading Widgets
You can either assign a callable to options that returns an update to
date list of items or pass them in at display time. To use a callable
do something like this:
#Define the callable somewhere
def get_item_list():
return [(item.id, item.name) for item in
model.Item.select(model.Item.q.active == True, orderBy='name')]
#Define the items like this
items = widgets.CheckBoxList(validator=validators.Int(), options=get_item_list)

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

(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

[TurboGears] Re: How to set validator in a custom widget?
This is because the above validator code doesn't take argumens. It
gets them directly from the form values. So you just have to amke sure
the form_values keys are corrently looked up in the validator, and
call it as:
chained_validators = [BirthDateValidator()]
But, if you want input support so you can use
chained_validators = [BirthDateValidator('month', 'day', 'year')]
or,
chained_validators = [BirthDateValidator(2005,10,1)]
you need __unpackargs__ like this:
class BirthDateValidator(validators.FormValidator):
messages = {
'invalid_date': Invalid date.,
'date_not_in_future': Date must be in the future.,
'invalid_visitors': You need to give a positive number of
visitors.,
}
__unpackargs__ = ('month', 'day', 'year')
def validate_python(self, form_value, state):
# access the values thru, self.month, self.day, self.year

[TurboGears] Strange problem when autoreload.on=False
Hi *, I'm experiencing a strange problem: When autoreload.on is set to True, my app works fine. As soon as I set it to False, the application starts up, but an exception (AssertionError: This transaction has already gone through ROLLBACK; begin another transaction) is thrown on every single call. For the typical stacktrace see below. The utils module, which provides methods for all controllers is always the source of the error. All controller methods that actually return a dict to the template use the utils module to provide standard entries to the dict, i.e. a localized menu structure, etc. : @expose(template=sometemplate) def some_method(self): content = self.get_some_specific_content() return self.utils.default_dict(some_special_extra=content) Within the default_dict method, the best available locale for the user is calculated and loaded from db. The line that bombs is a debug logging statement which outputs the iso code of the loaded locale. Has anyone experienced similar problems? Any ideas as to why this is happening? I'm using TG 1.0.1 and Postgres 8.2.

[TurboGears] Investigating TurboGears
Hi all, I'm considering implementing a TurboGears project at work, one because what I've seen I like, and we already like Python here. But I've got a couple of questions I hope people might be able to help me with, or point me in the right direction for more information. We've got a distributed system of processes running on mixed platforms (mostly Linux, but some Windows) which runs as a collection of crontab jobs, files being moved around in folders that awakening processes see, process and move on and XMLRPC communication channels between the detached systems, particularly the windows systems. So here are my questions: 1) I'm looking at Pyro as a communications mechanism between the distributed systems that have Python. Is it possible to support Pyro from within the TurboGears server? 2) To support the Windows machines, and perhaps 3rd party outside users, can I get XMLRPC support inserted into TurboGears in some way? Right now I really like the MVC approach, which TurboGears supports and promotes. In our case we're trying to centralize the Model (the database for us). But the Controllers and the Views could be on other servers, which is why I'm thinking about Pyro to connect to the Model. Any help, advice or warnings would be greatly appreciated, Doug --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.

[TurboGears] Setting SingleSelectField's options in form.display()?
Hi,
Title says it. Code as follows:
controller.py::
class UsersFields(WidgetList):
users = SingleSelectField(options=[(0,'')])
number = Textfield()
users_form = TableForm(fields=UsersFields())
def UsersController(controllers.Controller):
@expose(template='users')
def index(self):
# a) -- won't work.
form_data = {'number': 42, 'users':[(1, one), (2, two)]}
# b) -- won't work.
#form_data = {'number': 42, 'users':{'options':[(1, one),
(2, two)]}}
return dict(users_form=users_form, form_data)
users.kid::
${users_form(form_data)}
When rendering the template by accessing .../index, I get two
controls: one regular text field with the value 42 inside, and a
SELECT-control vith the value .
Where did one and two go? What am I doing wrong?
Thanks in advance,

[TurboGears] Re: Setting SingleSelectField's options in form.display()?
users_form() or users_form.display() take named arguments so if you
pass a dictionary with the arguments inside you need to apply ** to it
like this:
${users_form(**form_data)}
And you want something like this(the parameter names and then the
field's names whose parameter you want set):
form_data = dict(value=dict(number=42), options = dict(users = [(1,
one), (2, two)]))

[TurboGears] Re: Reloading Widgets
Sweet. Thanks. I thought about something along those lines before
reading the response, but I would have passed a call to the function,
get_item_list(), rather than the fuction itself, get_item_list. I
need to research why that works. Thanks again, I'll do my reading.

You can either assign a callable to options that returns an update to
date list of items or pass them in at display time. To use a callable
do something like this:
#Define the callable somewhere
def get_item_list():
return [(item.id, item.name) for item in
model.Item.select(model.Item.q.active == True, orderBy='name')]
#Define the items like this
items = widgets.CheckBoxList(validator=validators.Int(),

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):

[TurboGears] hosting problems
I recommend server pronto be removed from the list at http:// docs.turbogears.org/1.0/Hosting. The customer support is very poor, and their billing practices are insecure (they will publish credit card information on the web). I've outlined this in more detail at http://bewest.wordpress.com/ 2007/02/15/serverpronto-doesnt-understand-privacy-or-security/ and http://bewest.wordpress.com/2007/02/14/serverpronto-will-publish-your- creditcard-on-the-web/.

[TurboGears] AssertionError: This transaction has already gone through ROLLBACK; begin another transaction
I can't reproduce this error right now because TG fails to access
database.. but this was bugging me for the last few days. I have a
form with 4 drop down menus.. When first menu is chosen, it loads the
second through ajax. When second is chosen, it loads 3 4 through
ajax. (1st is country, second is state, 3 4 are county and city). It
works fine at home but on remote server only the second (state) menu
loads, when I change 2nd menu, 34 do not load and I get a traceback
from TG that goes, AssertionError: This transaction has already gone
through ROLLBACK; begin another transaction .
The code in question is this:
@expose(format=json)
def getCounties(self, state_id, tg_errors=None):
#print ###getCounties, counties, ,
model.State.get(state_id).counties
tmp = {id: 0, countyName: Select county..}
is_id = False
try:
state = int(state_id)
is_id = True
except:
state = state_id
is_id = False
if is_id:
counties = [tmp] + model.State.get(state).counties
else:
counties = [tmp] + model.State.selectBy(stateName=state)
[0].counties
return dict(counties=counties)
getCities is similar. Note that at home I just have try: State.get(id)
except: State.selectBy(name=state) and it works fine. On remote server
I tried to do this because I thought it might be related to the
Rollback error. It didn't help of course..
The reason I'm not sure if I will get an id or a name is that when the
menu is loaded from ajax, sometimes it will return name and sometimes
id. Menu created by me of course always returns id, as it well should.
Again, this doesn't cause trouble at home and I didn't investigate
this more yet. I don't think this causes the Rollback error though.
From my reading of the group it looks like there was an old bug that
was related to this but it was fixed. It was also possible to bring
this error about by passing around sqlobject object between
transactions (if I understood right) and also there was one case when
a function had an empty list as an argument and it was reused in later
transactions causing the error.. It looks like this case is something
different.
Here's the mochikit code..:
SCRIPT SRC=/static/javascript/MochiKit.js TYPE=text/javascript/
SCRIPT
!--document.write(STATES!!+states)--
script
var conn = MochiKit.Signal.connect;
function replace_state(req) {
var states = evalJSONRequest(req).states;
replaceChildNodes($('location_form_state_id'),
map(
function(p) {
return OPTION((p.id,p.stateName))
},
states
)
);
}
function replace_county(req) {
var counties = evalJSONRequest(req).counties;
replaceChildNodes($('location_form_county'),
map(
function(c) {
return OPTION((c.id,c.countyName))
},
counties
)
);
}
function replace_city(req) {
var cities = evalJSONRequest(req).cities;
replaceChildNodes($('location_form_city'),
map(
function(city) {
return OPTION((city.id,city.cityName))
},
cities
)
);
}
function state_id_changedb(event) {
var state_id = event.target().value;
var defb = doSimpleXMLHttpRequest('/getCounties', {state_id :
state_id});
defb.addCallback(replace_county);
}
function state_id_changed(event) {
var state_id = event.target().value;
var def = doSimpleXMLHttpRequest('/getCities', {state_id :
state_id});
def.addCallback(replace_city);
}
function country_id_changed(event) {
var country_id = event.target().value;
var def = doSimpleXMLHttpRequest('/getStates', {country_id :
country_id});
def.addCallback(replace_state);
}
function init_state_selector() {
