Thus, code that looks for =2.1.0-rc2 wants a version *later* than 2.1.0 final. Your requirement should list =2.1.0 instead. To avoid this problem in future, do not use '-' for prerelease tags; setuptools recognizes '2.1.0rc2' or '2.1.0.rc2' (or '2.1rc2') as equivalent prerelease versions, but '-' means post-release patch. Have you considered using text history file for releases? Then you don't have to guess the order of releases, the file can also describe branches: --- .egg-info/releases.txt ... 2.1a1 2.1.beta1 2.1.beta2 2.1.0-rc2 2.1.0 2.2alpha1 ... [2.1.0 bugfix] # 2.1 bug-fix branch 2.1.1-rc1 2.1.1-rc2 2.1.1 2.1.2-rc1 2.1.2 This way you can restrict upgrades to one branch like 2.1.0 bugfix.

[TurboGears] RuleDispatch version conflict
Hi,
I am having a problem to start a server after installing rev207 from
svn. I am running win2k. I had TG 0.8a3 and the latest setuptools
installed, and then I run:
1. easy_install RuleDispatch
2. setup develop (R207)
3. tg-admin quickstart (created project x)
4. x-start

[TurboGears] Re: About LocalizedSubmitButton.
This is a good point. All widgets should be localized using _(). This is only required for attributes, as the i18n_filter calls gettext on all text in Kid templates(if the i18n.runTemplateFilter option is on). BTW the LocalizedSubmitButton has been moved to i18n/widgets.py, along with some example widget classes.

[TurboGears] Reconnect to the database (mysql) when connection goes stale
Hi everyone! I'm about to release an alpha version of my TurboGears project to a client. Working with the framework has been a complete joy and my coworkers are amazed at how quickly I've been able to do the development. I have one small item I need to fix before I can let the client loose: my MySQL connection goes stale due to inactivity every night. I've read the relevant questions on the SQLObject list [1] but those posts are pretty old and I can't figure out how to apply those solutions in a TurboGears context. Has anyone else encountered this issue and dealt with it?

[TurboGears] Re: Reconnect to the database (mysql) when connection goes stale
Hi Liza, Glad to hear that your project has gone well! If it's going to be publicly available, I'm sure we'd all love to hear more about it when it launches. If this is a MySQL-related issue, I wonder if it would make sense to change SQLObject's MysqlConnection to detect if the underlying DBAPI connection has gone away and do something about it. The concern I'd have there is you'd get really weird behavior if the connection goes away while you're in the middle of a transaction. TurboGears knows if you're using a transaction or not, so we might be able to make a more intelligent decision about it in turbogears.database. I've seen the MySQL connection drops previously when using Java, though I think the Java JDBC driver for mysql had an ?autoReconnect option.

[TurboGears] Identity documentation
I'm trying to pull together some high-level documentation for identity. The way I see it, an end-user has three basic strategies for using the identity subsystem: 1. Use the default identity provider and model (include the default somodel, which creates separate User, Group, and Permission tables). 2. Use the default identity provider with a customized model, with user-defined tables that subsume one or more of User, Group, and Permission 3. Create a custom identity provider, and just implement the methods required by a provider. Jeff: is this the way you see it? From where I'm standing, #2 seems like the most common case for a typical end user.-- Tim Lesher [EMAIL PROTECTED]

On Wed, 2005-11-16 at 13:45 -0500, Jonathan LaCour wrote: Given that this is also possible, it seems like there are several different ways to do this off the top of my head: 1. WSGI middleware (I think) 2. CherryPy filters 3. SQLObject modifications 4. Decorators 5. Some mixture of the above 1. Unfortunately, CherryPy really only has very basic WSGI support - I don't know of any reasonable way to hook WSGI middleware up to Cherrypy at this point (maybe in a future release). 2. Filters in CherryPy won't work either, they don't allow you to wrap the request and I don't think there is any way to guarantee that they are actually run - especially if an exception occurs. 3. SQLObject modifications would be great, but until they are done we'll need to have an interim solution. 4. Which leaves decorators. My plan now is to implement a transaction decorator which will look something like: def in_transaction(func): hub = AutoConnectHub() def newfunc(*args, **kw): hub.begin() try: func(*args, **kw) except cherrypy.HTTPRedirect: hub.commit() raise except: hub.rollback() raise else: hub.commit() newfunc.func_name = func.func_name newfunc.func_doc = func.func_doc return newfunc The expose decorator will check the config / it's parameters and if a transaction is desired it will wrap itself in the in_transaction decorator. This doesn't give us strict per-request transactions if you have database code in your cherrypy filters. But I think any database code in filters would probably mostly be doing reads, so this doesn't seem to be a huge issue. It is probably possible to monkeypatch CherryPy to give us true per-request transactions if we really need them. The AutoConnectHub.begin method checks to see if we're already in a transaction, so calling one transaction-wrapped method from another will result in them both running in one transaction. I think this is the desired default behavior. If you need more transaction stuff beyond this, you can always write your own decorators to do things like nested transactions. And if there is enough demand we can add support for such things to TG in the future. Of course, if you want you can disable all of this automatic transaction stuff in the config and handle transactions yourself or not use transactions / database at all. Sean Cazzell
[TurboGears] Re: validation_error is going away right?
JW, That is in SVN now - if your method has a has_errors var it will get called instead of validate_error. Sean Cazzell On Thu, 2005-11-17 at 17:02 +, [EMAIL PROTECTED] wrote: I read in a post that validation_error was going away. Kevin said, That's a good point. If we deprecate validation_error, then the method can just be called directly and you can check form_errors to see if there's a problem. I think this also means that an invalid exception would never be raised. It simplifies the code, but it does also eliminate a visual reminder to check for errors. Maybe that's not so bad, though. The idea being that the method being called would receive a has_errors argument. The example Kevin gave is below: @turbogears.expose(input_form=myform) def save(self, name, address, age, has_errors): if has_errors: return self.index() Did this change ever make it into turbo-gears? I've been playing with validators and have really grown to not like the validation_error method of dealing with problems :). I'd really like to know what the new-method will be, if there is going to be one. Thanks, jw

a way to bind the function to the instance, is there not?

[TurboGears] MochiKit 1.1 Intro Screencast
I put together an introductory screencast for MochiKit this week, presented via the interactive interpreter example: http://mochikit.com/screencasts/MochiKit_Intro-1 This screencast was recorded with Snapz Pro X 2 and was encoded with QuickTime using the H.264 video and AAC audio codecs.

[TurboGears] Re: validation_error is going away right?
It was also noted earlier that has_errors may actually be redundant and can be eliminated in favor of just setting the errors on the request object.

The idea being that the method being called would receive a has_errors argument.

Speaking of internet connections - I am going to be out of town until Sunday, on vacation at a place with *no* internet connection, so I'll have to get caught up on the list Sunday night. I'm pretty close to having something ready to commit on the new expose decorator front. Things will be fully backwards compatible (expose will still accept and process validators and inputform args). The big changes are splitting the validators and inputform stuff out of expose into other decorators and adding implicit transaction support to expose. I'll throw up some docs on the wiki prior to committing. Have a nice weekend everyone.

[TurboGears] Can someone give me a hint about this @turbogears.expose thing?
Hello, I'm very new to TG and relatively new to python. I understand most of it, but something I could not yet get are these @turbogears.expose lines. I understand that it tells Kid which template it should serve, but the syntax is odd. It is executed right before a def - I didn't even know that python allows code there. And what does the @ mean? I could not yet find it in the python documentation (and googling for python @ doesn't really make much sense). I guess it's something really simple, but it would be great if someone could explain it to me. Thanks in advance.

[TurboGears] Re: Forms declarative style
In my TG CRUD work, I generate edit form, view list and view screen
from SQLObject. I use the similar approach of Kevin : using *arg or a

method. Advantages of this solution :
* easy to create and extends a form automaticaly
...
editWidgetMap = {
'container' : widget4edit.FormWidgetsList,
'default' : widget4edit.TextLineWidget,
'SOStringCol': widget4edit.TextLineWidget,
'SOStringCol+long': widget4edit.TextWidget,
'SOUnicodeCol': widget4edit.TextLineWidget,
'SOUnicodeCol+long': widget4edit.TextWidget,
'SOBoolCol': widget4edit.CheckBoxWidget,
'SOForeignKey' : widget4edit.VocabularyWidget,
'SOEnumCol' : widget4edit.VocabularyWidget,
#'SOIntCol':IntWidget,
#'SODateTimeCol':DateTimeWidget
}
def buildWidgetsList(self, sqlobj, widgetmap):
@param sqlobj the type (like app.model.Page) for wich create a
WidgetContainer
@param widgetmap the family of widgets to use for each
SQLObject field type
back = []
columns = sqlobj.sqlmeta.columns
for col in sqlobj.sqlmeta.columnList:
name = col.origName
clazz = col.__class__.__name__
if (clazz == 'SOStringCol' or clazz == 'SOUnicodeCol') and
not(col.length):
clazz += '+long'
widget = widgetmap.get(clazz,
widgetmap['default'])(key=name)
if hasattr(widget, 'vocabulary') and (widget.vocabulary is
None):
if clazz == 'SOForeignKey':
referencedsql = findClass(col.foreignKey)
widget.vocabulary = SQLVocabulary(referencedsql)
elif clazz == 'SOEnumCol':
widget.vocabulary =
widgetsupport.Vocabulary(col.enumValues)
if hasattr(widget, 'defaultValue') and
(widget.defaultValue is None):
widget.defaultValue = col.enumValues[0]
if hasattr(widget, 'required') and (widget.required is
None):
widget.required = col.notNone
if hasattr(widget, 'validator') and (widget.validator is
None):
widget.validator = col.validator
back.append(widget)
return widgetmap['container'](*back) #IGNORE:W0142
...
* the WidgetContainer instance could be attach to a SQLObject type. In
my case after building a WidgetContainer I do :
if not(hasattr(sqlobj, 'editWidget')):
#autogeneration of the editwidget
sqlobj.editWidget = self.buildWidgetsList(sqlobj,
self.editWidgetMap)
sqlobj.editWidget.append(widget4edit.HiddenWidget('isNew',
validators.Bool(), True))
sqlobj.editWidget.append(widget4edit.HiddenWidget('id',
validators.Int(), -1))
* you could create 2 instances of the same WidgetContainer, an each one
could have it's own internal state without interference, like 2
instances of TextField... (may be my java background influence me too
much, but class state/field are share by all instance, and there is
only one class definition available in the system)

then run:
easy_install 'CherryPy=2.1.0,!=2.1.0-beta,!=2.1.0-rc1,!=2.1.0-rc2'
Notice that this is just pasting the requirement from the error message
above (in quotes so the shell won't think the is a redirect).
This problem is being caused by the 2.1.0-rc2 version number, which
setuptools thinks is a post-release patch rc2 of 2.1.0, not a
prerelease release candidate (which would be spelled 2.1.0rc2 or
2.1.0.rc2). As a result, it thinks the egg you have is newer than
the one that's needed, when in fact it's older.
Kevin, Ian: if I may make a suggestion... it might be easiest to fix
this issue in the field by releasing a CherryPy 2.1.1, and making
TurboGears and PasteScript depend on that, rather than trying to get
people to fix their individual installs like this. Meanwhile, I'll
continue doing penance for not having put prominent enough
documentation in the setuptools manual about how version number parsing
works. (It's buried in the pkg_resources docs under Parsing Utilties
