WebHelpers 1.0b2 released

2009-12-21T17:51:50Z

WebHelpers 1.0b2 is released.

Feedgenerator is updated to the current Django original, and the
GeoRSS classes added. Please test it with your newsfeeds, including
those using the 'published' property. (The 'generator' and 'source'
properties are still disabled until somebody can tell me what exactly
they should be.)

I'm not sure about one aspect of the GeoRSS code. It's putting the
longitude first in the XML file, and I've heard contradictory things
about whether it should. Does anybody have Justin Bronn's email
address, the author of the Django GIS code? I emailed Jacob but he's
out of town.

The other biggest change is in the HTML tag builder implementation.
It passes the tests and works with my site, but let me know if you
have any problems.

The deprecation of webhelpers.markdown has been canceled. The other
changes to markdown() to make it work with other Markdown
implementations remain.

Here's the full changelog since 0.6.4:

1.0b2 (2009-12-21)
------------------
* webhelpers.constants:
- Fix spelling of Massachusetts.
* webhelpers.feedgenerator:
- Sync with Django rev 11910. This adds GeoRSS and makes the API more
extensible, as well as fixing a few bugs.
(Re-added the Atom1 'published' property.)
(The 'generator' and 'source' properties were lost, but they weren't
working correctly anyway.)
GeoRSS usage: use the Geo\* classes and add ``geometry=(lat, lon)`` to
each news item. Other shapes and a (not yet implemented) Geometry class are
allowed; see the source.
Note: you should specify the latitude first, but the longitude appears
first in the newsfeed. This is a feature, to comply with the spec.
* webhelpers.html:
- New ``HTML.cdata()`` method for producing "<!![CDATA[ ... ]]>" sections.
- The basic tag builders (``HTML.a()`` and ``HTML.tag("a")``) now have a
``_nl`` arg which, if true, inserts a newline between content elements
and at the end of the tag for readability. Example:
HTML.a("A", "B", href="/") => '<a href="/">AB</a>'
HTML.a("A", "B", href="/", _nl=True) => '<a href="/">\nA\nB\n</a>\n'
This does not affect HTML attributes nor the higher-level tag helpers.
The exact spacing is subject to change. The tag building code has been
refactored to accommodate this.
* webhelpers.html.tags:
- ``form()`` puts its hidden "_method" field in a '<div style="display:none">'
to conform to XHTML syntax. The style prevents the div from being displayed
or affecting the layout. A new arg ``hidden_fields`` may be a dict or
iterable of additional hidden fields, which will be added to the div.
- Set magic ID attribute in ``hidden`` helper to match behavior of the other
tag helpers.
- ``image()`` can now calculate the width and height automatically
from an image file, using either the PIL algorithm or the pure Python
algorithm in ``webhelpers.media``. It also logs the dimensions to the
debug log for troubleshooting.
* webhelpers.html.tools:
- Reimplement ``highlight()`` using the HTML builder. New arguments add
flexibility. Deprecate the ``highlighter`` argument, which creates tags
via string interpolation.
- Fixed ``auto_link()`` to parse slash characters in query string.
Patch by hanula; Bitbucket issue #10.
- Fix HTML overescaping and underescaping in auto_link(). Patch by Marius
Gedminas. A parsing bug remains:
http://pylonshq.com/project/pylonshq/ticket/657
* webhelpers.markdown / webhelpers.html.converters:
- ``webhelpers.markdown`` will not be upgraded to the version 2 series but
will remain at 1.7. Users who want the latest bugfixes and extensions
should download the full Markdown package or the alternative Markdown2
from PyPI.
- The ``markdown()`` helper in
``webhelpers.html.converters`` now has support for external Markdown
implementations. You can pass a specific module via the ``markdown``
argument, otherwise it will attempt to import ``markdown`` or fall back
to ``webhelpers.markdown``.
- To see which version is autoloaded,
call ``_get_markdown_module()`` and inspect the ``.__file__``,
``.version``, and/or ``.version_info`` attributes of the return value.
* webhelpers.media:
- Bugfix in ``get_dimensions_pil``.
* webhelpers.paginate:
- Change for SQLAlchemy 0.6. (bug #11)
* webhelpers.pylonslib:
- Fix HTML overescaping. Patch by Marius Gedminas.

1.0b1 (2009-11-20)
------------------
* Delete deprecated subpackage: rails.
These are replaced by new helpers in date, html, misc, number, text.
* Delete other deprecated subpackages: commands, hinclude, htmlgen, pagination.
Pagination is replaced by paginate.
* webhelpers.constants:
- ``uk_counties`` returns tuples rather than lists.
* webhelpers.feedgenerator:
- ``rfc3339_date`` now accepts date objects without crashing.
- Add 'generator' and 'source' properties to RSS2 feeds. Patch by
Vince Spicer.
- Add 'published' property to Atom1 feeds.
* webhelpers.html.converters:
- New helper ``render()`` formats HTML to text.
- New helper ``sanitize()`` strips HTML tags from user input.
* webhelprs.html.tags:
- New helper ``css_classes()`` to add classes to a tag programmatically.
- Fix bug in tag helpers when passing 'id_' argument (although 'id' is
recommended instead).
- Add OptionGroup class and optgroup support to select(). Patch by
Alexandre Bourget.
* webhelpers.html.tools:
- New helper ``strip_tags()`` deletes HTML tags in a string.
* webhelpers.paginate:
- Allow all versions of SQLAlchemy > 0.3.
- convert "_range" and "_pagelink" function to Page class method so that they
can be overridden
- pager "onclick" argument use template string value. So, javascript code can
use "partial_url" or "page" value or any. Backward compatibility is
considered.
- Add presliced list option to avoid slicing when list is already.
* webhelpers.pylonslib:
- is now a package.
- The ``Flash`` class now accepts severity categories, thanks to Wichert
Akkerman. The docstring shows how to set up auto-fading messages using
Javascript a la Mac OSX's "Growl" feature. This is backward compatible
although you should delete existing sessions when upgrading from 0.6.x.
- ``webhelpers.pylonslib.minify`` contains enhanced versions of
``javascript_link`` and ``stylesheet_link`` to minify (shrink) files for
more efficient transmission. (EXPERIMENTAL: tests fail in
unfinished/disabled_test_pylonslib_minify.py; see
http://pylonshq.com/project/pylonshq/ticket/466 .)
* webhelpers.text:
- Port several helpers from Ruby's "stringex" package.
+ ``urlify()`` converts any string to a URL-friendly equivalent.
+ ``remove_formatting()``
+ If the ``unidecode`` package is installed, these two helpers will also
transliterate non-ASCII characters to their closest pronounciation
equvivalent in ASCII.
+ Four other helpers reduce HTML entities or whitespace.

Yes, TG 1 and 2 are working fine without virtualenv. You only get
problems when you want to run TG apps based on different TG versions at
the same time.

include my own java script into turbogears 2.0

2009-12-21T13:25:21Z

Hi,

Is it possible that I can include my own java script in Genshi
template without writting ToscaWidgets?
Here is what I have in my template but it does not seem to work. It
does not pick up my script.

<script src="${tg.url('/public/javascript/mylayout.js')}"></script>

I am using TG 2.0. Is the above method only applicable in TG 1.0?
btw, my /public directory resides at the same level as /conrollers and
/templates directories.

thanks much in advance.

You can use the User.validate_password() method for this purpose. Have a
look at the User class in the file model/auth.py.

I think you somehow managed to botch your python installation. And
whatever keeps virtualenv from working kills your installation as well.
So I'd suggest you try & fix python itself, and make VE running.

help_text='Please enter a value'),
TextField('field2', label_text='Field2')]
submit_text = 'submit'

Now, when I am not giving any value in field1 and clicking 'submit'
button, I get error like:

TypeError: pylons_formencode_gettext() got an unexpected keyword
argument 'domain'

Struck trying to install on Snow Leopard

2009-12-20T12:46:22Z

First, the virtualenv script seems broken. I asked in the virtualenv
group and they say it needs to be regenerated or something. It
generates the following error:

python tg2-bootstrap.py --no-site-packages tg2env
New python executable in tg2env/bin/python
ERROR: The executable tg2env/bin/python is not functioning
ERROR: It thinks sys.prefix is '/System/Library/Frameworks/
Python.framework/Versions/2.6' (should be '/Users/todd/Projects/iParq/
tg2env')
ERROR: virtualenv is not compatible with this system or executable
[todd]~/Projects/iParq>sudo python tg2-bootstrap.py --no-site-packages
tg2env
Password:
New python executable in tg2env/bin/python
ERROR: The executable tg2env/bin/python is not functioning
ERROR: It thinks sys.prefix is '/System/Library/Frameworks/
Python.framework/Versions/2.6' (should be '/Users/todd/Projects/iParq/
tg2env')
ERROR: virtualenv is not compatible with this system or executable

So fine - I try the manual setup instead. I successfully create the
virtualenv and activate it.

Then run the easy_install script

easy_install -i http://www.turbogears.org/2.0/downloads/current/index
tg.devtools

and it chugs for awhile and then dies with

File "/Users/todd/Projects/iParq/tg2env/lib/python2.6/site-packages/

So what am I doing wrong?

Re: TG2 mako templates and preprocessor

Jose, you should create a trac ticket for this.

Btw, why don't you use Genshi in the first place if you want to have
something that plays well with html editors and IDEs? If performance is
really an issue, I wouldn't use a preprocessor.

SingleSelectField Widget

2009-12-19T20:37:48Z

Hi,

Any toscawidget gurus out there?

I'm using a TableForm with a SingleSelectField widget with TG2. Can someone please advise how I can update the SingleSelectField options parameter when the page is displayed. I have no problem adding the options parameter when the widget is initialised, however I need to update the select control dropdown list based on user selection. How can this be done?

Thanks,

Michael

TG Admin too slow

2009-12-19T10:55:09Z

Hello everyone,

I've developed an app using tg 2.0 and it uses the admin frontend to
do the
CRUD stuff.
The problem is that the interface is too slow, I mean, it takes
about 25~30
seconds to load and not only the first time. Every time that I switch
to another
model takes the same time.
I've used wireshark to see what was happening and I realized that
the browser
reloads in every request all the css and the js files. These js are
from the
dojo library and sprox widgets.
I'd like to know if there's a workaround to solve this or if I'm
doing something
wrong.
When the browser request one of my own css, it sends the 'if-
modified-since'
header and the server response 'not modified'. But, with dojo and
sprox js
this doesn't happens.

Any ideas?
Cheers,
Mauro Ciancio.

Beaker has a two-level cache, you can cache any arbitrarily pickle-able
object in the cache[x] at the key [y] using the code shown in the 2.1
docs. Encode the parameters in a canonical format into a unique
(string) key and use that as the sub-key for the cache. That works with
2.0 as well (we use it extensively in one customer's application). Note
that pickles are not secure, so only trusted processes should be allowed
to write to your cache (i.e. memcached must be heavily fire-walled if
you're going to use that as your beaker back-end).

HTH,
Mike

Re: Validation in tg2

2009-12-19T07:07:13Z

You state "The validation is not working". What does that mean? Are data types failing to be converted? Is invalid data being accepted? Is valid data being rejected? Is the code simply giving a stack trace?

Without more information, we can't even guess. All we'll be able to do is say "Well, that kinda sucks."

Use one of the various memoized-caching-decorators for your API-call.
Recipes can be found on ASPN.

If am understanding the docs, that will cache an entire page view.
Not what I need.

I just need to cache one or two calls from within my controller, but
from what I can tell, the pylons cache demands an "argument-less"
call.

Am I understanding the docs right?

Let's try that again...Gmail seems to have sent my mail early...

Ah, I see now.

According to the Pylons docs here:
http://pylonshq.com/docs/en/0.9.7/caching/

it looks like you are correct, the expensive function cannot have any
arguments.

However, there are a couple of ways around this.

1. You could wrap your expensive function in a argumentless function, and
store the args someplace else. Then have your argument-less function get
the args from wherever you stored them and call you expensive function. You'd also need a function to generate a uniqe key for each set of args.

Modifying the example, something like:

class Example(TurboGearsController):

    self.tempargs = []

    def _expensive(self, *args):
        # do something expensive
        return value

    def _argless_wrapper(self):
        return self._expensive(self.tempargs)

    def key_func(self, *args):
        # generate a key based on your args
        return key

    @expose()
    def index(self, *args):
        self.tempargs = args

        c = cache.get_cache("example_cache")
        x = c.get_value(key=key_func(*args),
                        createfunc=self._argless_wrapper,
                        type="memory",
                        expiretime=3600)

2. Just memoize the expensive function, just like you would if you weren't doing anything with a web framework. In other words, don't use the beaker cache at all. Google for "python memoize" and you'll find a bunch of recipes, decorators, etc. which might make this easier for you. Most of them probably won't let you expire things based on a time limit, but you could probably adapt them to do so if you really needed to. I would probably go this route. Here's a couple of links:

http://code.activestate.com/recipes/52201/
http://code.activestate.com/recipes/498110/

Hope this helps!

Kevin Horn

Also, note that if you use option 2 above, you'll have to do something to make sure the "cache" is shared between threads. This should be handled automatically if you used the Beaker cache.

If am understanding the docs, that will cache an entire page view.
Not what I need.

I just need to cache one or two calls from within my controller, but
from what I can tell, the pylons cache demands an "argument-less"
call.

Am I understanding the docs right?

Arbitrary caching in TG2.1?

2009-12-18T10:52:00Z

Hello,

I have a "slow" call in my controller to an external API. I would
like to do short-term (10 mins.) caching of the results returned, as
many of the same calls are made rapidly.

Found docs at:
http://docs.turbogears.org/2.0/Caching

However, the docs mention that I can't call the "expensive" function
with any args. In my case, the call must take a number of request-
dependant arguments.

What should I do?

Thanks,
:)

The setter method in the default auth.py model file already does that
for you automatically if you store a user password, and you can modify
the encryption method there as you like.

How to encrypt password

2009-12-18T04:43:18Z

Hi All,

In TG 1, I was using the following code to encrypt the user given
password
identity.encrypt_password(data['pwd'])

In TG2, need help to use like that.

Regards,
Ranjan

I wanted to change SQLAlchemy session settings slightly: namely, set the
autoflush flag to False when running batch jobs (it has been noticed to
speed up my scripts by 2x or 3x).

I would have preferred not to take the risk to break the controllers by
doing so, but I finally took it :-) (the model itself is covered by unit
tests)

I think your only chance then is to have your own config-module thingy that
you import in model/__init__.py, and check for a certain variable being set.

If you are in the commandline tool code, make sure you import this module
*first*, alter the setting, and *then* import model-code.

I agree though that it really sounds like a bad idea. What is the actual
problem you try to solve with that?
