 I'd like to give some suggesting, for improving this document. It is very
 helpful already and, incidentally, had just the information I was looking for
 today, but you godd make it really good, with just a few enhancements:

I have gone forward and implemented the suggested changes myself and updated
the code for the cherrypy filter method so that it can be used as a base class
for your root controller.

If some of you could check it out and comment, that would be appreciated.

[tg-trunk] Config files

[Mark Ramm]

Sorry it was late, and was both confused, and said what I meant in a
confusing way.

What I'm talking abut is a way to parse our old config files to pass into
cherrypy as required.

Right now we have a central config system, which is only passing stuff to
cherrypy's global config.

We need to parse it differently and pass it to the cherrypy global config,
and app.cfg.

But the real question (as Kevin noticed, in spite of my obtuseness) is how
we deal with the tree/app config split.   Mounting sub-applications in trees
is one of the main things we need at my work, it would be great if we could
work this out in a way that let's us be backwards compatable with our old
config file format.

Though I haven't been a 100% fan previously, hearing from Jim Fulton
that Zope is moving toward PasteDeploy just makes me that much more
certain that using PasteDeploy as the deployment config file format is
a good way to go. The format was generally functional, but it seemed
(from working with it last year) that there were some places where it
could be smoother.

It will probably be possible to maintain some level of backwards
compatibility. But, if we decide to make a move like that we'd likely
want to switch over entirely to standard INI files so that all of the
config files use the same format. It may also be possible to perform
automated conversion between old formats and new.

In truth, this shouldn't be that bad since we don't fully support app
composition in TG 1.0 as it is.

[tg-trunk] TurboGears and CP3

[Mark Ramm]

So, many of our tests are very tightly coupled with the CP2 way of doing
things.   But the actual TurboGears code is not nearly so tightly coupled,
and we are now able to process requests with a quickstarted app (we get a
stacktrace due to some configuration work that isn't yet done, but we can
fake it.

Internal server calls need to change, and we probably need to determin the
API we want to use for mounting applicaitons at other places than the root.
Once we get things working in an acutal applicaton, we plan to go back and
write some new tests that are less tightly coupled to CherryPy.

The nicest bit so far is cherrypy.url which will let us make the turbogears
url() function way less complicated.   Woo--hoo for code removal!!!

So far we have only one change that will impact end users so far:

*  simple_cookie has become cookie on both the request and response objects.


If you're interested in following along, all of this work is happening in
the cp3 branch.

Have you considered using paste.fixture for the functional tests?  
That would decouple the tests from CP completely as it treats the  
whole cow as an opaque WSGI app which is ideal IMO. I did some  
experiments with paste.deploy and CP3 a while back which I have here  
[1] if you guys want to take a peek. The paste.app_factory entry  
point that builds the CP3/TG WSGI app is implemented here [2].  
Something similar can be done to create the app that needs to be fed  
to  fixture's TestApp. Just some thoughts

You guys are doing an amazing job out there at PyCON! (so great  
you're distracting me too much from this project that's keeping me

[TurboGears] Re: select_ from_ inheritable_ tables

[svetl]

Hi!
Thank you for your response.
I will try to describe my problem more precisely.
In model.py file there are the following classes:

class Base((InheritableSQLObject):
 created  = DateTimeCol(default=DateTimeCol.now())

class BaseSample(Base):
  name = StringCol(length=40, alternateID=True)

class BaseData(Base):
  sample_id = ForeignKey(BaseSample)

On the web page user must have opportunite to find samples.
The fields for seach are described in controller.py file:
def sample_search(self, tg_errors=None, **kwarg):
 order_list = [('name', 'sample name'),
   ('created', 'time of recording')]
  # fields in search form:
  name = widgets.TextField(name='name', label='Sample name')
  before = widgets.CalendarDateTimePicker(name='before',
  label='Created before,
  convert=True)
  order = widgets.SingleSelectField(name='order', label='Order
by',
options=order_list)

  if kwarg.has_key('order'):
  if str(kwarg['order']) == 'name':
  order_by = model.BaseSample.q.name
  if str(kwarg['order']) == 'created':
   order_by = model.Base.q.created

result = [list(model.BaseSample.select(query, distinct=True,
orderBy=order_by))]
...
query consists criteria for sample search. If one selected
orderBy = model.Base.q.created, TG gives the following error:
ProgrammingError: ERROR:  for SELECT DISTINCT, ORDER BY expressions
must appear in select list
SELECT DISTINCT base_sample.id, base_sample.child_name,
base_sample.name
FROM base, base_sample
WHERE base_sample.name) LIKE ('%S%'))) AND ((base_sample.id) =
(base.id)))
ORDER BY base.created

How I can add the fields in select list?

I tried to resolve this problem with Select(SQLExpresion). In this
case I can't define distict (it also important for my task), because
Select hasn't parameter distinct.

Best regards
Svetlana

  model.Base.created =='12.12.06')), orderBy=model.Base.created)

  It gives an error and I undestand why. Because this select query
  generates the following:
  SELECT * FROM tables base_sampl, base WHERE.
  The fields (*) in SELECT query are all from table 'base_sample'. In
  this place
  there are no fields from table Base, but orderBy needs the explicit
  field name
  from table 'base' (class Base).

 The above clearly isn't what you actually have in your code, or it gives you a
 different error altogether. Because you miss the model.Base.q several times.

 Please verify that you really have working code.

 Apart from that, it should work like this (note the usage of Base

 model.Base.select(AND(your-criteria, model.Base.q.childName
 == 'BaseSample'), orderBy=model.Base.q.created)

Your whole design is flawed because of improper use of InheritableSQLObject. 
It is not meant for mere column adding for arbitrary objects. You should be 
able to do that by simply subclassing from SQLObject. 

InheritableSQLObject is meant for class hierarchies like 

Car-Mercedes
 -BMW

not for just adding some common fields.

Redesign it that way, and things should work as you try to make them work.

[TurboGears] Newbie Question about Model Designer

[Michael Petroni]

hi all,

i'm just new to turbogears and have a question that may be answered 
easyly by one who knows turbogears better than me.

when i create a project with identity support (tg 1.0.1), the model 
designer of the toolbox does not see the intially created model. even 
worse, when i create some model there and generate the code for it, the 
old model information for identity support (user, group, permission, 
etc.) is lost.

is there a way to reverse engineer the model from the model.py into the 
model designer or at least to start over with a model such as it is 
initially created by a project with identity support?

thx to all,

rg.

[TurboGears] Re: TurboLucene now has documentation!

Krys,

Yeah, read the mailing list archive (it's not very long yet :) and I think
that using Elixir statements at least would make that sort of thing pretty
easy.  I'm sure you could also work up a more general (non-Elixir) solution.

Good luck!

I'm hoping to have a look at the source (though it way be a couple of weeks
before I get the chance), so hopefully, I can come up with some more
specific suggestions in the future.

[TurboGears] Disabled fields validating as not_empty=False?

[Mikael Jansson]

Hi,

I've set a bunch of fields to disabled in order to make them read-
only, so I can re-use a WidgetList for both creating and editing data
(i.e., I don't want to be able to change the data once it's set for
certain f fields).

Now, most of these have not_empty=True set as a condition in their
validators. Which is good when creating a new object. When I want to
edit them, I set add a dict(disabled='disabled') for certain fields.
However, that makes them disappear from the input!

Why is this, and what can I do about it if I still want to re-use my
forms?

Thanks,
Mikael

[TurboGears] Best way to pass on URL parameters?

[Mikael Jansson]

Hi,

I've got an exposed method that gets called with /do?id=N (def do()),
that displays a form and posts it to /action (@error_handler(do) def
action()).

Problem is that I want to pass on the ID parameter to the 'action'
method. How do I do that the most convenient way?

Do I use a table with an extra field? If so, is there a way of adding
fields to a TableForm /after/ it has been created? This all boils down
to being able to re-use forms for both creating and editing -- the ID
field /cannot/ have not_empty=True for the create form (as the
object has not yet been created), however it /must/ have
not_empty=True for the edit form.  Also, per a previous post to this
group, hidden fields seem to validate as not_empty=False.

Any suggestions?

Thanks in advance,
Mikael

I found if you put all your changable sets in the DB, hooked TG to an
MXMLC compiler, have the Kid template spit out  ActionScript, and
created/edited the SWF in CatWalk, it just worked.

I am tinkering with the SWF having an edit mode right now, but it is
primitive.  Just a button press (Cricket Compiler) to recompile the
page, drag the images around to reposition, editing the text in the
page.  I am gonna try and add a Flex based control panel next.

I think it would be potent if attached to a better library of
ActionScript than I know how to write.

One thing, creating/editing the page in the browser, it is irritating
not having an image editor for the browser, and having to drop out of
a web based environment to edit images for the web.

 No need, people buy flash websites all the time. I don't know about the

 I don't really like *most* flash sites myself. But I sure as heck intend

 Hi,

 I've got an exposed method that gets called with /do?id=N (def do()),

 Problem is that I want to pass on the ID parameter to the 'action'
 method. How do I do that the most convenient way?

 Do I use a table with an extra field? If so, is there a way of adding
 fields to a TableForm /after/ it has been created? This all boils down
 to being able to re-use forms for both creating and editing -- the ID
 field /cannot/ have not_empty=True for the create form (as the
 object has not yet been created), however it /must/ have
 not_empty=True for the edit form.  Also, per a previous post to this
 group, hidden fields seem to validate as not_empty=False.

Discriminate on value, not on existence. By that I mean that I always have an 
id-field - it's just negative in case of create.

And HiddenFields are vailadated as all other fields as well, I just use

id = widgets.HiddenField(validator=validators.Int(not_empty=True))

all the time.

[TurboGears] Re: Disabled fields validating as not_empty=False?

 Now, most of these have not_empty=True set as a condition in their
 validators. Which is good when creating a new object. When I want to
 edit them, I set add a dict(disabled='disabled') for certain fields.
 However, that makes them disappear from the input!

 Why is this, and what can I do about it if I still want to re-use my
 forms?

The browser won't spend bandwidth sending information from disabled fields.
If you said they're disabled, why should they be sent again?  Their value
remains the same or isn't interesting on the context the form was submitted. 

To use the same form you'll have to use a different validation schema.  There
you omit the unneeded fields.

You can set text fields to 'readonly' instead, but then, there is no visual
feedback to the user that they are not editable (for browsers that handle CSS
attribute slectors that can be easily changed).

But neither setting fields to 'disabled' or 'readonly' prevents malicious users
from sending other data for those fields back to your server, so server side
validation must be used anyway, as always.

[TurboGears] Re: Turbogears app with two database-connection?

[Jim Steil]

I have the same situation here.  But, I've taken a totally different 
approach.  We have an ERP system running on an AS/400.  I have LOTs of 
other little apps that access data (mostly order and sales history info) 
from the ERP system.  Instead of dealing with the AS/400 database and 
two db's in TurboGears, I have written synchronization scripts that run 
nightly to grab data off the production AS/400 and bring it in to my 
MySQL database.  This works for me because for my needs, day old data is 
acceptable.  The other added benefit is that I can now dictate what the 
model looks like and can make it play nice with SQLObject.  The 
synchronization scripts are not difficult to write.  Also, I've been 
playing with another open source tool called JitterBit which will do the 
whole thing for you if you have a server you can spare for it.

I don't know if this will work in your environment, but this is the way 
I was able to implement the same kind of thing.  Also, I haven't tried 
it, but does SQLObject work with Interbase?  I thought there were only a 
few databases supported.

 Had the same situation here and TurboGears provides some very nice

 handle it. Just split your model into two different packages and use
 turbogears.database.PackageHub.

 For example:
 -
 legacy.py
 __connection__ = turbogears.database.PackageHub(myapp.legacy)
 (my legacy model)
 -
 model.py
 hub = PackageHub(quarantine)
 __connection__ = hub
 (your app model)

 Use the configuration system to define different credentials:
 sqlobject.dburi = mysql://foo:[EMAIL PROTECTED]/mydb
 myapp.legacy.dburi = mysql://bar:[EMAIL PROTECTED]/xams

 
 would i have two separate models for each database?
   
 yes.

All the questions, and the answers for each question

You can have a widget (simple, compound, whatever) for each answer if
you like. As long as the widgets are similar, this fits the model of a
repeating input widget.

Or, if the answers are of the kind pick one out of N, typical for a
poll, a multiple radio button for each question is enough.

In this case, you have a repeating widget where each repetition contains
a multiple radio button (or singleselect, multipleselect, multiple
checkbox, whatever).
You can fill the options of the radio buttons with a list filled at runtime

form_args = {
   'repetitions': {'questions':len(poll.questions)},
'options': {'questions':[ {'answers':get_answers(question)} for
question in poll.questions ]},

[TurboGears] Re: Turbogears app with two database-connection?

[Johnny Blonde]

Hello Jim,

yes, it does work with interbase using the firebird driver... it at
least for now does what i need ;-)

well, i fear it won´t be enough to copy the data once a day or twice,
because some data has to be looked up in realtime. after the first
lookup some data will be replicated to the new database by the new
application.

i first was thinking of just replicating it every hour or so, but the
ceo told me, it won´t be enough, as data needs to be FAST, man... so, i
´ll try it this way...

Frank

[TurboGears] Filtered options

[Jim Steil]

Hi:

I'm working with a SingleSelectField where I'd like to limit the values 
that are going into the select list.  Here is my situation:

I have users and plants.  A plant can have multiple users and a user can 
be in multiple plants.  I want a dropdown list of all of the plants for 
a specified user.  The model for the user and plant objects follow:

class User(SQLObject):
class sqlmeta:
table = tg_user

user_name = UnicodeCol(length=16, alternateID=True, 
alternateMethodName=by_user_name)
email_address = UnicodeCol(length=255, alternateID=True, 
alternateMethodName=by_email_address)
display_name = UnicodeCol(length=255)
password = UnicodeCol(length=40)
brillLogon = UnicodeCol(length=10, dbName='brillLogon')
active = BoolCol()
created = DateTimeCol(default=datetime.now)
# groups this user belongs to
groups = RelatedJoin(Group, intermediateTable=user_group,
 joinColumn=user_id, otherColumn=group_id)
plants = RelatedJoin('Plant', intermediateTable='userPlant', 
joinColumn='userId', otherColumn='plantId')
   
class Plant(SQLObject):
class sqlmeta:
style = Style(longID=True)
idName = 'plantId'
   
plantNumber = IntCol()
name = UnicodeCol(length=50)
initials = UnicodeCol(length=3)
active = BoolCol(default=True)
users = RelatedJoin('User', intermediateTable='userPlant', 
joinColumn='plantId', otherColumn='userId')

I normally fill my dropdowns with the getXxxxOptions as detailed in the 
TurboGears book.  As such, the following is my code to fill the plant 
dropdown (when not limited by user)

def getPlantOptions():
plants = Plant.select(orderBy='plantNumber')
options = [(0, '-- None --')]
for plant in plants:
options.append((plant.id, plant.name))
return options

But, what I really want to do is pass a userId into this method as a 
parameter so I'm only putting in the plants for a specific user.  Is 
there a way to do this?  If so, can someone point me in the right 
direction to figure out how I can do it?  What I'd really like to do is:

def getPlantOptions(userId=0):
if userId != 0:
   u = User.get(userId)
   plants = u.plants
else:
plants = Plant.select(orderBy='plantNumber')
for plant in plants:
options.append((plant.id, plant.name))
return options

But, then I wouldn't know how to specify it on my field def.  Here is 
what I do for the non-filtered dropdown:

plant = SingleSelectField(label='Plant:', 
options=qlfOptions.getUserPlantOptions)

I don't know where I'd supply the parameter.  Would I do it somehow in 
the controller?

[TurboGears] Form widget with default values set from identity and validation decorator

[Alex]

Hi,

I'm trying to create a form in which some of the select field defaults
are set from values obtaied from a user's identity. So for example to
default a country selection to the user's default country from their
profile.

Because I only have access to the user's identity within my Page
classes I'm currently creating a fields class, which i then insert
additional values into within my Page class before creating the form
widget and returning that. This way I can set the default values
appropriately at the time the widget is created.

Doing this however, the form widget can't be used in a validate
decorator on my save method as it's not in the global scope.

Is there a way to do this so that I can have the benefits of a
validation decorator and set the defaults from the identity?

Alex

a system with limited (flash) storage.  I am aware of the various
compressed filesystems available, but I'm considering other
approaches.

Is it possible to deploy a TurboGears application with all/some of
it's source .py and .kid files gzipped to save space?

e.g. If foo.kid can't be found, foo.kid.gz should be read instead.  So
long as the .kid and .py files do need to be accessed randomly, there
should be no need to gunzip the file.)

These are text files, so 3:1 compression may be possible.

I have a feeling (as functions are first class objects in Python, like
Ruby) that it may be possible to redefine a few IO functions to
achieve this.  Any hints would be welcome.

Regards,

Chris.

[TurboGears] Re: Investigating TurboGears

[writeson]

Diez,

Thanks for your feedback, I will try implementing a test harness for
Pyro and XMLRPC and see how far I get.

Again, thanks for our feedback,

 You can use everything python has.

  2)   To support the Windows machines, and perhaps 3rd party outside

 Yes. It is never a problem as a client, and TG can even work as server.

[TurboGears] TurboGears for Mac OS X install fails.

[shredluc]

Hey guys,

the TurboGears easy_install fails for an installation against a OS X
os.

It tells me that it cannot find a page for 'RuleDispatch.'

When i go to http://cheeseshop.python.org/pypi/RuleDispatch , the page
does not exist.

I downloaded the .egg file manually (RuleDispatch-0.5a0.dev_r2115-
py2.4-macosx-10.4-fat.egg) and install using easy_install -f .
TurboGears (while in the dir with the egg files) and it still is
trying to access the site.

Any help would be appreciated.

Thanks,

[TurboGears] Having very wierd TG problem, error msg with master or templates?

[[EMAIL PROTECTED]]

Hi,

I'm having a very strange TG problem.  The problem manifests itself
somewhat randomly; the error messages seem to alternate between the
below, this one (http://groups.google.com/group/turbogears/browse_frm/
thread/2704d1ef2faf4e1f/3b5b74d075d4e5bf?lnk=gstq=tclass+%3D
+mod.templaternum=2#3b5b74d075d4e5bf), and no errors.  The page used
to work fine, and I just added some new HTML div and span elements
into KID and all of sudden I have these errors.  I'm not able to edit
the page without causing these errors, though if I revert back to base
it always works.

I'm not sure what is going wrong?  My templating is correct, as is the
master.kid paths and all variables passed into the KID page.

I'd doubt that the templates would work, but the sources would. It's a
non-trivial amount of effort though.

You're probably prematurely optimizing though. Is it work that much
effort to save (if you're REALLY lucky) about 1MB?

[TurboGears] Re: TurboGears generated MardiGras page

[gogoxoom]

Hi, Sam,

Listen, you're doing some very interesting work. The message behind
your development comes across as clearly experimental and not to be
reviewed in terms of usability (yet*wink*). I think you're onto
something. Please, stay the course and continue to share your findings
and examples. Per the previous post by ian duncan, he's spot on in
terms of marketability. Do you have some example code posted somewhere
or that you'd be willing to share?

Go a step further and provide some visual feedback to your audience
(e.g. pre-loader). It makes a world of difference rather than looking
at a gray box for some indeterminate amount of time. This could be
accompanied with a small explanatory tag denoting your intent/
inspiration. It probably won't make the 'nay-sayers' love a particular
technology any more but they might come to appreciate the approach
you've provided.

I hope this message encourages you to keep it up.

Jes

 I think it would be potent if attached to a better library of

 One thing, creating/editing the page in the browser, it is irritating
 not having an image editor for the browser, and having to drop out of

 But, then I wouldn't know how to specify it on my field def.  Here is
 what I do for the non-filtered dropdown:

 plant = SingleSelectField(label='Plant:',
 options=qlfOptions.getUserPlantOptions)

 I don't know where I'd supply the parameter.  Would I do it somehow in
 the controller?

Yes, in the controller:

user_plant_widget = SingleSelectField('plants', options=[]) # put
default/dummy options in

@expose('project.templates.user_plant'
def plant(self, user):
options = qlfOptions.getUserPlantOptions(user)
return dict(widget=user_plant_widget,
params=dict(options=options))

And somewhere in user_plant.kid:

...
${widget.display(**params)}
...

That will pass the options in when the page is rendered for the given
user.

If your SingleSelectField is part of a form or other compound widget,
you'll need to pass the options differently. I can't remember the
syntax exactly for TG widgets, but for ToscaWidgets I think it would
be (untested, from memory)

@expose('project.templates.user_plant'
def plant(self, user):
options = qlfOptions.getUserPlantOptions(user)
child_args = dict(plants=dict(options=options)) # child named
'plants' gets the keyword argument 'options'
return dict(widget=user_plant_widget,
params=dict(child_args=child_args))

The pattern for TG widgets is similar, but it's not child_args, its
something else, and I think the structure might be different.
Sorry, can't remember any docs on it, I had to grok the source to
figure it out back then. I've been using toscawidgets since they were
released, much better IMO.

Yes, there is :) The form parameter to @validate can be a callable,

e.g.

   updated. So somehow i guess the browser must cache these lists (IE 
   and firefox both show this behaviour). Both controller A and B are 
   secure resources so a session is maintained. Might that be the 
   reason or is it something completely different? Most importantly 
   however, how do i get
  around this?

[TurboGears] cursor passing into kid

[tml]

Hey,

I'm curious what the best practice is for passing data fetched from db
into a kid template.

I'm doing a fetchall() on the resultset gotten from a SA select, and
passing the resulting python list to kid to iterate and display items.
Would the better and efficient way be to just send the result set into
kid and ask it to iterate over fetchone() ?

thanks.

If there's no typo here you're not passing a callable but the result

def makeOptions(results, labelColumn, seperatorColumn=None,
AddNull=False,MultiLang=False):
 def get_options():

 try:
 label = getattr(result,labelColumn)

[TurboGears] Re: TurboGears generated MardiGras page

[SamFeltus]

I can post some code when I get it together, but, it is code that just
works, is COMPLETELY undocumented and at this time not easy to use
without a demo.  I didn't know any ActionScript 3 when I started.  The
code needs plenty of work.  But, the swf files are manufactured in the
browser with TG, minus the image editing...

Here is an HTML intro with links...  I'll try and make it more useful
later...
http://samfeltus.com/site_index.html

ActionScript 3, MXMLC compiler, the new Flash VM, Linux support and
Flex are major upgrades.  I expect the web is fixing to be bombarded
with a new generation of Flash content.

It's not a problem for TurboGears, cause it's trivial to output
ActionScript instead of HTML...  Loose coupling is a good thing, and
allows for happy accidents...

There are no unit tests...  I just ran it in the browser until it quit
crashing...

 Go a step further and provide some visual feedback to your audience

 at a gray box for some indeterminate amount of time. This could be
 accompanied with a small explanatory tag denoting your intent/

I like the first one because the python list is more natural for kid,
than a result set. Also it's less information being pass to the kid
template which will make both the compilation and resulting py file
smaller.

Also the first approach is more close to MVC then the second one.

if your really concern about efficiency the best will be to code it
both ways and benchmark it.

 Python itself can import zipped files (zip, not gzip AFAIK).  I've not tried

 it might be able to.

[TurboGears] ? about passing objects into kid templates!

[hamilton ganesan]

Hi All,

I notice that its easy to pass objects into a kid template but.. when you
try to pass that same object from the
same kid back into turbogears , the object loses its integrity :-(

Is there some way of passing objects from kid templates into turbogears
functions without the object undergoing any changes?

you lost me there, TG works one way the dispatcher in CP (aka the

tg.url()

could you provide an example of what you want to accomplish maybe it's
an issue with the type of the object your trying and not all objects.

[TurboGears] Re: AssertionError: This transaction has already gone through ROLLBACK; begin another transaction

[Jorge Vargas]

On 2/26/07, Rainy [EMAIL PROTECTED] wrote:

 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 .

first of all if it works ok on one env and the other we should list
the differences, if your using different db engines maybe you have hit
a bug in one of SO's backends. there is no reason for code to work
different on two hardwares with the same environment.

 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)

just a note on the structure of the code, instead of using the same
variable to store the key param and the string param why not add 2
named params something like
   @expose(format=json)
   def getCounties(self,state_id=None,state_name=None,tg_errors=None):
   if state_id:
   state = int(state_id)
   counties = model.State.get(state).counties


   state = state_id
   is_id = False

   if is_id:
   else:
   counties = [tmp] + model.State.selectBy(stateName=state)
[0].counties
   return dict(counties=counties)


also the tmp variable is not a good idea I don't see why your turning
it later into a list why not just leave that on the template and just
move the actual data in the controller, it's always going to be
Select county right?

 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 :

That might be true, but your design is still flawed. Sooner or later you

taking place for an unnecessary case.


All you want from your base-class is to propagate created-columns

a needless waste, and will get in your way soon.

  -bob

 That's a good point about it being premature optimisation.

 If the (application *and* framework's) .py and .kid files are only
 1.5Mb, I would save 1Mb.  I expect there are more than 1.5Mb of
 files.

 Even 1Mb is good if you've only got 16Mb.  I should have more than
 that, but you're fighting bloat all the way with flash.

 With the work involved, I may be better off storing much of the
 application/framework on some form of compressed (read-only?) loopback
 filesystem.  I was (perhaps naively) hoping that you could set
 USE_GZIP = TRUE in a configuration file.

Well dependent libraries are easy enough if they're egg zip
compatible, you don't have to do anything -- they're already zipped.
You said TurboGears application, not the rest of the stack. Still not
really worth spending much time on though.

A compressed filesystem like squashfs or cramfs is a much easier and
more standard approach to this sort of problem *and* it will compress
things like extensions and executables (which dwarf Python bytecode
most of the time) where any other solution will not. If you truly
constrained to double digit MBs you're going to want (perhaps even
need) to use one anyway for the rest of the OS.

I have my own object which I pass into my kid template (via a dict). I can
in the kid template treat that object as normal and access any of its
attributes.

I then want to pass that very same object ( e.g YYY) (via a form) from the

in the turbogears function it gives me a unicode type.???

[TurboGears] Re: Strange problem when autoreload.on=False

[Jorge Vargas]

 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?

check out a similar thread with the name of the error your getting, it
seems that your SO objects are leaving longer then expected and that
is causing troubles.

Also remember that http request/responses and therefore CP/TG
request/responses are supposed to be atomic so this is a chance your
using a dead object.

can you add ?debug=1 to your dburi, that way you can see the SQL and
see when it is actually making the bad request and it could be track
to where the sql was generated.

 I'm using TG 1.0.1 and Postgres 8.2.

 Regards,
   Puck
