If you wanted to automate, put it in the git hooks, puppet or capistrano or whatever deployment engine configs.

Re: deform: is it possible to invalidate a form / field manually ?
You can set either a field validation:
Validation function:
database_username_re = re.compile('^[a-z0-9_]{2,16}$', re.IGNORECASE)
def validate_database_param(param):
if database_username_re.match(param):
return True
else:
return unicode('Value must be between 2 and 16 characters and
can only contain uppercase and lowercase alphanumeric characters or an
underscore')
Schema definition:
databasename = colander.SchemaNode(
colander.String(),
validator=colander.Function(validate_database_param),
title = 'Database Name',
)
Or, in your actual Schema call:
def validate_userpass_existing(form, value):
checking to make sure we have a user/pass OR an existing user
exc = None
if value['databasename']:
db = DBSession.query(cp_database). \
filter(cp_database.device_id==value['device_id']). \
filter(cp_database.databasename==value['databasename']).first()
if db:
exc = colander.Invalid(form, 'Database name already in
use.')
exc['databasename'] = 'Cannot create a duplicate database'
if exc:
raise exc
schema = DBAddSchema(validator=validate_userpass_existing). \

Re: deform: is it possible to invalidate a form / field manually ?
Forgot to add: Validation on the field takes place on form submission. Validation on the Schema takes place after all field validations are validated. So, an error on a field where it has some constraint will not fire off your check on the Schema. So, if someone put a short password in, and you are checking to see if the user exists on the Schema validation, it actually will not check the username until the password validation passes. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

There is http://code.google.com/p/android-json-rpc/ which does handle
2.0, but, I suspect the library you're using is probably not sending
the rpc_version, rather than it being 1.0.
json-rpc 1.0 doesn't support named parameters and only supported
positional parameters, so, you would pass something like:
params: [asdf, qwer, , , , username]
json-rpc 2.0 would look like:
params: {name:asdf, company:qwer, login:username}
As you might imagine, that alone is going to be quite a showstopper.
If commenting out that check worked, you're probably using json-rpc
2.0 and should be pretty safe and I suspect that is the main reason
pyramid_rpc forces json-rpc 2.0.

I did see someone had ported pieces of Twisted to 3.2, but, I don't believe there is anything official. To my knowledge, even though Tornado supports python3.2, I don't believe it supports PEP 100% due to some string handling issues and there were bugs filed for it when I last looked in October.

Re: Usability is the most biggest problem of Pylons Pyramid.
http://highscalability.com/ has a number of case studies as does http://www.allthingsdistributed.com/ and are pretty good references. As for a consolidated FAQ, there are so many variables, there is never a best for every solution. In every case, you have to know what your stumbling blocks are in order to fix them. And you can't just look at the benchmark of the day because many are not run properly or aren't anywhere near testing real world situations. For one project I'm working on, I thought my use case was rather specific. After evaluating nine potential solutions and implementing two test projects in two separate long polling/ajax push scenarios, I realized that my initial design wouldn't work and that none of the solutions were optimal for what I needed. So, I had to pull the decision making back a layer and then I could implement almost any long polling solution - each worked as long as I had the ability to access named pipes. The battles with noSQL versus SQL are almost as religious as which noSQL solution is best. Do you need streaming map/reduce? do you care about immediate or eventual consistency? Every decision brings a dozen solutions and each solution needs to be evaluated. There are people that will pick their favorites and become experts in those and in 90% of the cases, you can usually shoehorn an idea into the tools in your skillset. The fundamental differences between riak, mongodb, couchdb, cassandra, etc. are there, but, it would be hard to say that any of them couldn't be engineered to handle most of the nosql use cases. While it would be nice to say, a + b + c + d = fastest, you need to qualify that as 'fastest in this situation'.

Python UTF-8 defaults, Paster and Pyramid/mod_wsgi
When pushing an app to production today, I was hit with:
TypeError: expected byte string object for header value, value of type
unicode found
Of course, the reason was that I was adding headers to the HTTPFound
headers = []
headers.append( (str('P3P'), str('CP=IDC DSP COR ADM DEVi TAIi
PSA PSD IVAi IVDi CONi HIS OUR IND CNT')) )
but, hadn't wrapped them with str().
Now that Python defaults to unicode for strings, WSGI is going to
break unless a string is explicitly set to a string rather than the
default unicode.
a simple mapper in Pyramid would fix this, but, I'm reluctant to
commit that as it is a hack which still hides the problem, and, could
break things later on.
Thoughts? or document and let everyone figure it out on their own?

a=((u'1', 'checked'), (u'13', 'checked'))
('1','checked') in a
True
('13','checked') in a
True
('14','checked') in a
False
Changing the order of the arguments to (('checked',u'1')) does work,

In our applications we use 'sqlalchemy.pool_recycle = 3600' When you get that error, it means that pool_recycle is mysql's idle timeout - increasing the timeout will increase the possibility that this will happen. The first question to address this is, are you connecting via socket or tcp? because you MIGHT be hitting a TCP timeout rather than a mysql idle timeout. If so, you need to fix that from the TCP side. Most operating systems will default to 600 seconds, however, your pool_recycle time of 30 seconds should be well under that. One possibility is to reduce pool_recycle to 10, or, turn echo_pool on in your debugs to see what is happening. With pools, it is possible that you have an idle pool that is being hit that has timed out. If it persists, you could import NullPool and set poolclass=NullPool, however, that might introduce threading/concurrency issues on a busy system. I've run pool_recycle at 10 to eliminate that problem, but, I connect via sockets rather than tcp on most machines. Also, you might check wait_timeout= to see if that value is set too low. I don't recall if sqlalchemy uses CLIENT_INTERACTIVE or not - I don't believe it does, which means interactive_timeout= isn't the variable to set.

It will fail a few times, then start working for a bit and continue that way. I'm wondering if you ran the app under paster, ran a bunch of wget -S on a small page, typescript so that you capture the output, then, ran the same under apache/mod_wsgi. Another thing to do, modify the code in chameleon right before the return to print the body and encoding. Possibly it is getting a value that it isn't expecting? Write to a file so that you know the last file contains precisely what is failing, or, wrap it with a try/except to write the body when it does fail. Since it happens on the login page, unless you're touching the database here, I suspect it is either an odd translation (which would not really happen intermittently) or some odd session variable that isn't being encoded. Position 467 seems far enough that it might not be in the header, but, that would depend on any cookies that are being set.

Re: Pylons, Apache reverse proxy/virtual hosting domain names
Some providers will set up wildcard hostnames, i.e. *IN A 1.2.3.4 whereanything.domain.com will be resolved to the name. What it looks like based on the check is that the ONLY thing set up currently is domain.com. At a minimum, you would need to define A records (or CNAME records to point to domain.com) for each hostname, or, if they support wildcard DNS, set that up. Usually when a domain is created, domain.com and www.domain.com are set up, but, that doesn't appear to be the case with what you've presented. So, your DNS provider is the one that can fix this. If you have it hosted at almost any registrar that offers DNS, you can usually set this up through the Domain Registrar's control panel. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Webhelpers html tag examples
Mike Bayer (of Mako and SQLAlchemy) posted this:
http://techspot.zzzeek.org/2008/07/01/better-form-generation-with-mako-and-pylons/
While it discusses Pylons, it does address one possible method without
using a form library (or, using Mako as a form library). The method
isn't limited to Mako, you could do it with Jinja2 or any other
reasonably powerful templating language.
I like deform - it has some very sophisticated widgets that make
developing some rather complex forms easy. The only issue I have
(coming from an SQLAlchemy background and not a zodb background) is
that it requires some magic to bring appstruct over to an object that
SQLAlchemy can use.
http://cd34.com/blog/framework/using-pyramid-with-deform-to-editcreate-records-in-sqlalchemy-backed-database/
WTForms is very Djangolike and works pretty well. We used it as the
form library for Apex. Formalchemy's documentation is in a state of
flux. They swapped maintainers moved the site, some of the links 404.
If you are looking for a form library that is very well tied to your
SQLAlchemy model schemas and has a RESTful interface, it works pretty
well.
If you're just looking to use webhelpers in your existing forms, you
would add it to your subscribers:
something like:
project/lib/subscribers.py:
from pyramid.threadlocal import get_current_request
from project.lib import helpers
def add_renderer_globals(event):
request = event.get('request')
if request is None:
request = get_current_request()
globs = {
'h':helpers,
}
event.update(globs)
project/lib/helpers.py:
from webhelpers.text import plural
from webhelpers.date import distance_of_time_in_words
from webhelpers.date import time_ago_in_words
project/__init__.py:
config.add_subscriber('project.lib.subscribers.add_renderer_globals',
'pyramid.events.BeforeRender')
In your template (Jinja example, Mako would use ${ } rather than
{{ }}:
br /span id=p-{{data.id}}{{h.plural(data.points,
'point', 'points')}}/span by a href=/user/
{{data.author.username}}{{data.author.username}}/a

Pyramid addons that are not part of the pyramid project
While developing applications that run on top of Pyramid, having other people find those projects becomes difficult without having pyramid somewhere in the project name. If someone searches github or any of the other repositories, the search function is somewhat inadequate in finding projects without Pyramid in the proper name. Projects have no way to easily signify that they are an addon, yet, are not part of the project. What I would suggest is a naming convention for pypi packages that are related to pyramid, but, not endorsed. Perhaps something like pyramid_ext_ or pyramid_app_. Django applications use the django. prefix and there is little confusion as it is the expected naming convention. I feel that the name Pyramid needs to be in the name somewhere so people looking for apps and extensions that work with pyramid are easily found. It is a two way street - it makes it easier for projects using Pyramid to be found, and, having projects with the Pyramid name in it will validate the framework as having activity and an external development community supporting it. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Sure, for simple stuff it's easier than building HTML by hand, but

everything's hidden from me.
I have an object which is a few string fields and then a list of
references to Tag objects. The input for the rest of the object is
fine but I can't see any way to handle the tags, because the way the
schema seems to work is that it assumes the object is composed of
everything within it, as opposed to associating with things outside of
it. So I can add new tags to the object, but that is not the behaviour
I want, because the user needs to be limited to existing tags.
What you want is to use the deferred decorator and then pass your
values along using .bind()
http://deformdemo.repoze.org/deferred_schema_bindings/
Something like this using

Re: Pyramid addons that are not part of the pyramid project
pyramid_registration does pretty much what Apex does - or appears that it will. Apex is just auth + registration on top of pyramid. CSRF and Flash messages were added into it because CSRF should be included in any front-facing webapp and Flash messages just made it easier to communicate events with a user when they signed in, registered or their password was invalid. Supporting i18n should be done for any app developed in the 21st century. Same with Pyramid_openid - which is just authentication with Pyramid using OAuth2 as a provider. At what point does a toolkit become an application? You can't do anything with Apex except auth and registration. You can't deploy Apex as an application - the app would do nothing but allow someone to register and sign in. This is similar to Akhet which is a layer on Pyramid to give developers a more pylons-like environment. Kotti does have CMS features and by definition appears to be an application or framework that uses Pyramid as a base which would be ineligible. I imagine someone new to Pyramid may not find Kotti, or, may not make the association that it has quite a few CMS components available and ready for a Pyramid app. While you may not want to endorse external apps or show preferences, I think it benefits the communities on either side. I'm not really that concerned about it for Apex, but, having an easy to find set of extensions and apps should raise awareness for pyramid - if that is a goal. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

testing with DummyRequest() when view requires access to cookies
When testing with DummyRequest, HTTP_HOST and SERVER_NAME aren't set.
As a result, one of two things needs to happen:
pyramid/authentication.py (line 377)
cur_domain = environ.get('HTTP_HOST', environ.get('SERVER_NAME'))
If cur_domain doesn't find either HTTP_HOST or SERVER_NAME, cur_domain
is set to None which causes a TypeError:
/pyramid/authentication.py, line 388, in _get_cookies
if ':' in cur_domain:
TypeError: argument of type 'NoneType' is not iterable
One possible workaround in the test code is to set the environment
locally:
environ = {
'HTTP_HOST':'test.com',
'SERVER_NAME':'test.com',
}
request = testing.DummyRequest(environ=environ)
However, should testing.setUp set certain variables to a sane default,
perhaps 'localhost' unless overridden? pyramid.paster.bootstrap seems
to properly handle this, but, the pyramid.testing doesn't.
Perhaps a more forgiving default could be used to avoid the exception?
The TypeError as it is could point out incorrectly configured
deployments whereas a default of localhost might cause additional
trouble debugging deployment issues. Or, should the test setUp set a
bare minimum environment and more closely replicate bootstrap's
behavior?

Re: Removing *.fcgi from URL on redirect's
In wsgi, that url is built from the environment parameter SCRIPT_NAME. I haven't used flup, but, I would guess it might be the same.

you can do:

Re: pyramid - how to debug on production server?
How are you calling your .wsgi script? ScriptAlias / /path/to/script.wsgi or using mod_rewrite? What does the apache error log say that corresponds to the 404? mod_wsgi is pretty helpful with debugging messages. with mod_wsgi, you can touch the .wsgi file to get it to reload, or restart apache. Most daemon methods do that since they cache the code to avoid the startup penalty, which, makes it a bit more difficult to develop your application the way it'll be deployed. If you're doing development, I prefer using paster serve --reload development.ini which reloads each time it recognizes a file has been changed. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Insight for configuring Pylons with repoze.who
What I ended up doing for that project was actually leaving the
repoze.who/what tables alone and created a parallel table with my
data. That way, my schema changes wouldn't affect auth. On another
project I let the AuthUser model alone, but, defined my own definition
and set:
__table_args__ = {'useexisting':True}
allowing one table for auth and metadata without having to modify the
default models. Personally, I feel that both approaches are probably
incorrect and with Pyramid, I have overloaded AuthUser with my own
model so that I only need to do one fetch each time there is an auth
request and all extended data is present in the session (with a little
modification).
While each are probably valid approaches, the indirection of the first
two probably would confuse an external developer making modifications
or troubleshooting more difficult.

Re: how to use a model (persistence layer) with deform
deform is a form library that is not tied to your backend storage similar to a few other form libraries. Unlike FormAlchemy that is based almost exclusively on your models, the glue to attach deform to an SQL backend has to be written by you. There are likely some bugs in the url that follows as it was a proof of concept, but, I am using it during development of a production app. While I'm using mysql, sqlite should work fine with some minor schema changes.

Re: Routing question versus real world situation

RESTful really means that you are using the verbs available in HTTP, that is, GET, POST, UPDATE, DELETE without wasting name spaces like addsite, delsite, etc., in your URL. RESTful doesn't necessarily mean that you must *not* use a query in the URL (like ?site_id=1). So, for your sites, I would have the following CRUD: Create: /admin/site/ (POST) Read: /admin/site/id (GET) Update: /admin/site/id (PUT) Delete: /admin/site/id (DELETE) Meaning that for your subsites, you could have the following CRUD: Create: /admin/subsite (POST) (where parent ID and any other info would be in the POST body) Read: /admin/subsite/id (GET) Update: /admin/subsite/id (PUT) Delete: /admin/subsite/id (DELETE) I looked at this and the same real issue persists with CRUD/Restful. My terminology was wrong - this is for a client facing application where I wanted clean URLs. How does one signify a subsite is being added to a site? The only way I can see it being done is adding another route. With the default routes, /admin/subsite/1 would indicate that you are editing subsite 1, not adding subsite to site 1 It seems no matter what I come up with, I'm having to alter routes to handle things and it just seemed like I was overlooking something. I've got workarounds, but, I was just curious how other people have handled similar situations. Having clean urls just seems nicer, but, I think in this case I am relegated to using ?site_id=1.

If you intend to create a new subsite with a GET with /admin/subsite?site_id=1 as the path, how would you handle a user hitting multiple times the reload button? You'd create as many subsites as the number of times the reload button was hit and that's probably not what you want. The situation here is that there is a list of 25 sites (paginated). In order to use POST, each 'add site' button would be a form. Adding a site presents a 'new subsite' function that allows them to enter some data before saving, so, a user reloading a page repeatedly isn't going to create multiple sites. By the way, I realize that you said in your original mail that the controller is admin (AdminController). I think that's what might be your problem. You should have a controller per entity, such as site (SiteController) and subsite (SubsiteController). Each having all the necessary CRUD methods (Pylons actions) like paster restcontroller subsite subsites would create for you. You would then just need to add map.resource(site, sites, path_prefix=/admin/) and map.resource(subsite, subsites, path_prefix=/admin/) in routing.py. (I have never played with path_prefix kwarg, so you might want to double check how it behaves). This way you wouldn't need an AdminController at all if all you want to have is the prepending /admin/ path in your URL to make it pretty. I'm leaning towards that. Right now I've got 3 controllers, admin, client and manager. The theory was to keep each of the backend areas in a controller but, I'm finding that layout to be problematic. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Why not use routes like
/admin/addsite
/admin/site/{site_id}
/admin/site/{site_id}/delete
/admin/site/{site_id}/addsubsite
/admin/site/{site_id}/subsite/{subsite_id}
/admin/site/{site_id}/subsite/{subsite_id}/delete
I think this is probably the direction I'm going to head. I was
actually curious if I was just not understanding how applications were
intended to be written around the default routes, or, if adding in
routes was the sign of me not understanding the zen of Pylons.
Switching from ToscaWidgets to FormAlchemy has also been instrumental
in cleaning up urls.

Re: paging a sqlalchemy query object give a typeError
First, Pylons 1.0 is current, debian is a little bit behind. 0.10 is essentially Pylons 1.0 with deprecation warnings to ease transition from 0.9.x. I use paginate in a number of projects the way you describe using: Pylons 1.0 WebHelpers 1.2 SQLAlchemy 0.6.5 exactly how you describe. Paginate was broken a while back during the transition to Pylons 1.0. Your environment has webhelpers in the wrong place and is loading the wrong version. Debian doesn't install its packages into /usr/local/lib so I'm reasonably sure that is the issue. The question is, how did it get there. If you did an easy- install as root, it might have placed it there, but, cleaning that is probably the first step to diagnosing it. I believe you can edit easy-install.pth in the /usr/local/lib/ python2.6/dist-packages directory and possibly remote the WebHelpers-0.6.4 directory which would remove that library. Make a backup of that directory first just in case. Second, I really would suggest you use a virtual environment for doing pylons development. This way, when you're developing code or multiple projects, you don't have a ton of dependencies installed on your main machine. Projects that you've written that haven't changed can stay on the same version without fear that the API will change when you do an apt-get upgrade. http://pylonshq.com/docs/en/1.0/gettingstarted/#installing contains some basic instructions. or wget http://pylonshq.com/download/1.0/go-pylons.py python go-pylons.py --no-site-packages pylons cd pylons source bin/activate easy_install mysql-python paster create -t pylons project cd project (edit development.ini to alter the IP address, port, sqlalchemy url, etc) paster serve --reload development.ini This creates a subdirectory named pylons whereever you are. Perhaps you want to use /var/www/pylons or /home/username/pylons as the location. When you go back to doing development, you cd /var/www/ pylons, source bin/activate and your environment is modified to run in a sandbox. Whatever you do in that virtual environment doesn't affect the main system. apt-get upgrades don't affect your sandbox either. So, if debian upgrades to a version of software that would break your project, your virtual environment insulates you from the system change. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Routing question versus real world situation
I have an app I'm putting together that has a common UI issue, but, I wasn't sure what the typical pylons method was to handle it. Basically I have: Add Site site Edit | Delete | Add subsite site Edit | Delete | Add subsite subsite site Edit | Delete | Add subsite subsite site Edit | Delete | Add subsite The controller is /admin/ and I have urls of /admin/site to create a new site, /admin/site/id to edit the site and /admin/delsite/id to delete a site. However, I am faced with the situation of adding a subsite to an existing site without some hideous hack. I can't really do /admin/addsubsite/id where id = the parent site id because that would invalidate the ability to later edit that subsite. I'd prefer a restful uri or something without get parameters, but, temporarily I've resorted to ?site_id=1.

Re: Pylons for Facebook apps
Parts of the REST API are still required and preloading FQL is another issue that needs to be addressed. While decorated actions make sense, I find that I almost have an all or nothing situation with a controller. The one loophole that used to be present with facebook was closed in June eliminating the need for a controller that never asked for privileges. With 2.6, one could just decorate the controller. I think overloading BaseController would provide the simplest integration path. That is the path I took with python-sdk and my latest app. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Pylons for Facebook apps
One thing I seriously debated was whether a single Pylons instance would be used per app, or, whether a single Pylons instance would have multiple controllers, each handling a separate Facebook application. Currently, I have one Nginx with uWsgi (4 threads on a quadcore) that talks to a single Pylons instance. I have three different Facebook applications that utilize the Pylons virtualenv and three separate controllers. While the applications are somewhat interconnected and share the same database, tables are separated with prefixes for the non-interconnected pieces. I do have two other apps, one that uses Apache2/mod_wsgi/Django and one that uses Apache2/mod_wsgi/Pylons. I'm working on another using Nginx/uwsgi and Tornado for a portion. In my case, I felt creating separate virtualenvs outweighed some of the other issues I would run into. Whether my requirements justify a more generic approach, I don't know. As for whether it should be middleware, or a new controller, I think I would like to avoid it being middleware, though, I can see advantages for both. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Their example for the App Engine requires it as well. While the methods do work and it is the library I have used for several projects, it doesn't handle everything within Python.

Re: Pylons for Facebook apps
But the session data isn't the hard part. If you're using pyfacebook, they are already suggesting that you use the Javascript SDK to handle auth and just read the session information from there which really eliminates the need for anything but Javascript/Python. Your controller just needs to make sure that it gets/keeps that session data from page to page, whether internally or through their canvas methods. Unless you're still doing FBML, there is very little that your controller needs to handle beyond making sure there is a valid, current auth token and one is passed on each FB Canvas pageload, though, not your IFrame Canvas pageloads. If you're doing IFrame Canvas apps, you've already got to use Javascript to handle quite a few authorization features or write your own popup handlers with the Facebook look and feel. Once you have the auth tokens, the wrappers around the Graph API are fairly developed. I think what I would like to see is a FacebookController method that allowed me to pass in my app id, secret, key, desired permissions etc. and would handle that transparently. My actions would then know the fb_uid for each request, and perhaps could have a method defined that would pass a variable to each action that contained my local session info. At that point, I can concentrate on the app without worrying about other methods. When the graph API fails due to permissions, a handler in the Controller could optionally prompt the user to add additional permissions and carry the action through. Passing information through the Invites/Friend Tagging so that referrals could be tracked would also be nice. Having the controller or attached methods generate properly formed urls and messages to handle those tasks would be nice. As for FBConnect, I believe Velruse handles many different OpenID/ similar authentication systems, but, still needs a backend hook through repoze or something similar. I could be wrong. -- You received this message because you are subscribed to the Google Groups pylons-discuss group. To post to this group, send email to pylons-disc...@googlegroups.com.
