Re: Are there references yet for SQLalchemy reflection and using multiple engines under pyramid ?
Thanks. This ended up helping quite a bit! I haven't gotten into multiple databases yet, but I think it should be supported trivially I refactored your code for re-use into this pastebin - https://gist.github.com/1556734 I tried to make it simpler, but there is a bit of a janky hack in there. 1. I stripped the ReflectedTable down to just being an inherited class type , and one which defines a __tablename__ 2. The map_tables routine now just takes an app_model directory and looks for items that have both a) inherited from ReflectedTable and b) define __tablename__ To make it work, just replace models/__init__.py with this This obviously needs a few more passes, but I'd like to really abstract this into something that can just be a standalone module to handle all this stuff. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: pyramid and social auth
I ran into similar confusions as you a few weeks back. What I realized is that Velruse - and some other packages - kind of exist as standalone authentication micro-apps that wrap other auth libraries, and not as libraries to build that functionality into your own app as you would want. For some projects, that works perfect. For others, you might want a specific user experience -- which will necessitate rolling a bit more code yourself around the auth libraries they wrap. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: SQLAHelper 1.0 released, and a proposal
I wish I was online over the holidays to take part in this discussion. Here's my .02¢ : - I think SqlAlchemy is the best ORM out there, and it's honestly been the deciding factor for me going with Pylons and sticking with Pyramid. - I think Pyramid core really needs to have a concrete DB/ORM plugin functionality / method / api / style. Whether you use SqlAlchemy or ZopeDB or something else, I think Pyramid should have a standard / recommended and documented place + support for starting up the DB connectivity. This doesn't need to be lines of code , it could just be a very well documented coding style / paster template. - I think the SqlAlchemy support needs to handle one or more databases , and both declaritive and reflective styles ( is there a third kind )? Pyramid is simply too free / open ended right now in regards to database support. It has the most potential out of all the frameworks, but its just frustrating at times. I started with the stock sqlahelper, and have been hacking at my integration to get more core SqlAlchemy functionality that it no longer resembles anything in published docs... if i had to hand this project over to someone else, i'd be worried that its so custom. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Serving Dynamic/Template js files
I *think* wyatt might be referencing a technique similar to how Facebook Connect works. - In your templates, you can just set a JS variable/object in JSON , and then have your external JS files reference it on load. - Between using that, and a lot of callbacks in your JS code, you can keep most of your client side scripting as a library that can be aggressively cached.

The opposite (as in a separate js file) however is true. And I wonder if it is better to be able to serve these small snippets as separate js files rather than inline, so that they get loaded even if downloaded via AJAX. I guess then I will have to assign a special view/route to these dynamic snippets, and render via a template. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Are there references yet for SQLalchemy reflection and using multiple engines under pyramid ?
I'm now using pyramid for some projects. Under Pylons I would almost always do the following: 1. Use multiple Engines ( Write, Read, Config, Log ) which each had different permissions in PostgreSQL. 2. Have my models reflect the database. With some custom routines, I largely just had to pass in a string for the tablename and a sometimes primary key . I'm not sure how to do that under Pyramid ( I am using the Akhet scaffold ). I might just use MongoDb for a bit, but would love to figure this out. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Model validation
I've built dozens of sites over the past 14 or so years , with Ad Agencies, Large Brands, Tech Startups, Major Media companies. Doing this, I've learned that Frameworks are really really great for the run-of-the-mill project that has a quick deadline, doesn't do anything new exciting, and has a shelf-life ( ie, it's expected to last 6-18 months and then it gets turned off ). For anything that needs constant improvement, nurturing, active product development and scaling of user interactions... frameworks have always been a complete fucking nightmare. Time and time again, I've seen my colleagues hit their heads against a wall ( often literally ) and wasting countless cycles trying to get around a 'design' or 'convenience' of a framework. I've also often seen months of work for projects that built on a framework thrown out and replaced with entirely custom Java/C/Python/etc code to solve the issues. I'm a big fan of using the right tool for the right job. If I'm needing to do a simple project that a 'framework' can quickly get off the ground and not need to maintain/grow it outside of that framework -- fine! But I'm well past the point in my career where I can justify saving an extra week off the initial launch plan to go with a convenience framework, when I know that I'm damning my dev staff to mundane and crap tasks like spending a week to customize a pagination plugin to work within the confines of that framework. I became a huge fan of Pylons/Pyramid , because a large majority of the stuff that lead people tend to abandon frameworks during project growth can be - and is easily - done within the environment. On Dec 13, 4:59 am, rihad ri...@mail.ru wrote: So it's a perfect tool for writing a framework :) Lightweight in my understanding means few features, mostly glue code. Just like Pyramid. All other meaty, but nonetheless important features, are meant to be chosen by a developer using that framework, and plugged in. For example, AFAIK Pyramid has no Form/validation subsystem in its core, or even an official plug-in that it endorses. Through trial and error, you have to just pick the missing part from the plethora of what's available, that would suit you functionally and esthetically. Maybe in the long run this would make you a more savvy, professional developer. But you'll have to agree with me, that if our goal is to build bigger, less buggy programs, we're gonna have to abstract from smaller details, use bigger bricks, so to speak. That's why people have chosen C, not assembly to write most parts of a larger OS; PHP, Perl or Python over C for web work, Frameworks over plain PHP, Perl or Python to facilitate building even larger programs. And that's because a human, however smart he or she is, cannot hold all the miniscule details in his head. People can see the bigger picture more clearly. So unless there's a larger framework built on top of Pyramid, as it is now the learning curve of getting the needed tools and do some CRUD/DB/auth/form edit/add, lists/pagination with some custom functionality - is pretty slow. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: how to add query parameters to the current url in view code?
Exactly what do you want to do - and why ?
You're talking about adding a new sort parameter to the current
url. If you meant that you want to change the URL, then you have two
options:
1. return a pyramid.httpexceptions.HTTPFound . you'd want to do this
before you touch the database or any other code
2. in the html template, have some javascript that will update the
window.location to reflect changes
That being said, I suspect you might be going about this wrong.
I don't understand why you would want to change a URL , or create a
new sort parameter for the URL. In this scenario, as long as there
isn't a sort parameter, you'll always execute that default code. I
see little benefit in redirecting to a new URL if you already have
code to correct for it.
You should also check the user submitted param , to ensure that it is
valid or allowed. i showed this in the 2nd example.
=
from pyramid.httpexceptions import HTTPFound
@view_config(route_name=countries_list, renderer=countries/
list.html)
def list(request):
countries list - with HTTPFound
if request.GET.get(sort):
sort = request.GET.get(sort)
else:
new_url = 'whatever code you want here'
return HTTPFound(location=new_url)
dbsession = DBSession()
countries = dbsession.query(Country).order_by(sort)
#TODO:how to return current url with new sort parameter ?
return {countries: countries}
=
@view_config(route_name=countries_list, renderer=countries/
list.html)
def list(request):
countries list, condensed, and with some sort of check
sort= 'default_sort_order'
if request.GET.get(sort):
submitted_sort = request.GET.get(sort)
if submitted_sort in [list,of,valid,sorts]:
sort= submitted_sort
dbsession = DBSession()

Re: Production.ini
You may be over-thinking this. The only good reason I've encountered to not have the passwords within the codebase, is worries of : 1. a web config makes the file viewable as plaintext 2. a web config makes the file's revision control info viewable as plaintext 3. not trusting the source control management server to be secure 4. not trusting team-members who have source access The *easiest* ways i've found to overcome this are : 1. stuff the login/passwords into a file that is not in source control 2. stuff the login/passwords into environment variables You can also code your apps so development servers pull the dev logins out of the codebase, but the production servers use the not-under- source-control files or environment variables. Forcing a 'person' to provide this info will hurt your ability for automatic deployments, make scalability a mess, and a host of other issues. This is just my 2¢, but it applies equally to any programming language or web framework i've encountered.

I think its in that sqla fork I shared with you too. if you stick to the following paradigm, it works well: def form_dispatch: if request.submit: return self._form_submit return self._form_print def _form_print: return render(form) def _form_submit: try: form.validate except FormError: return self._form_print() redirect( form_success_url ) -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

question about middleware
i'm trying to port an old perl project ( which was essentially middleware for the mod_perl environment ) to Pyramid/WSGI The basic premise is that it: - migrates the x-fowraded-for header into remote-addr - but only from accepted servers by ip - but only from accepted servers with a lan secret this way, your app functions as normal with no necessary logic needed, and you can toss it behind as many loadbalancers or proxies you need. the 2 issues i've been running into are: 1. how should I configure this? Should I have the middleware import config stuff ( if so, is there a reference ?) or should that all happen in the pyramid app when I layer in the middleware ? 2. is it even possible to raise a 403 in middleware and prevent the app from running ? -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: question about middleware
thanks. the accepted ips don't need to be db based. the notion is that you can trivially ensure that a request is through your gateway and doesn't have spoofed headers if the application recognizes both a the ip of the server and a secret that only those ips would know. for example, you would configure nginx working as a load balancer onto 4 machines in round-robin style... and have it add a header of (QU#EKJHADS to each request. so long as your app recognizes the header and the ip, it processes it as normal. otherwise, its either a spoof or some local traffic that you don't want to code for. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Pyramid/Pylons Project status update...
Great news to see traction! I've been busy porting over a microframework we used under Pylons for many projects to Pyramid and shared with some trusted friends. The application design is changing quite a bit due to pyramid, so its a complete rewrite. I'm taking this as an opportunity to just start publicly releasing stuff now, and not worry about security issues ( which kept back public release of the previous framework). The goal is to build out a framework for very quick prototyping of web applications, while not enforcing any requirements on the database or overall application design. https://github.com/jvanasco/pyramid_opensocialnetwork -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

it's probably not the response text from the AJAX call.
Otherwise it would definitely help to see the server-side code you're

Re: Attach SQLAlchemy Session to settings object instead of creating module global?
have you looked at the pyramid_sqla stuff ? i think mike orr may have done some of this. in my pylons apps, ive never needed sessions to persist between requests.. so i looked more at global settings and request based stashes. On Feb 24, 9:51 pm, Wyatt Baldwin wyatt.lee.bald...@gmail.com wrote: In Pylons, there's a recommended SQLAlchemy setup where the Session is created as a module global and then configured by a call to a function in the model package. I've been using a variation of this setup in my Pylons apps, but as I've been porting to Pyramid, I've been thinking it would be cleaner to attach the Session to some application object. One possibility is attaching it to the settings dict. I wouldn't want to add it to the WSGI app returned by `main` because that app may be wrapped by other middleware and then the Session would be hard or impossible to access. I'm thinking it would look something like this: def main(global_config, **settings): settings = init_settings(global_config, settings) config = Configurator(settings=settings) settings['db.Session'] = make_session_factory(settings) # ... return config.make_wsgi_app() def make_session_factory(settings): engine = engine_from_config(settings, prefix='sqlalchemy.engine.') Session = scoped_session(sessionmaker(bind=engine)) return Session What I think is preferable here is that there is a single place where the database stuff is set up and there is no possibility of using the Session before it's fully configured. Also, accessing the Session in a controller wouldn't require an import, which is slightly more convenient though not really a big advantage. So, my questions are: - Has anyone tried a setup like this? - Are there any down sides I'm not thinking of? - Is there maybe a better high level application object to attach the Session to? - Am I over-thinking this? After I wrote all this, I found something in the cookbook about using a non-global session: http://docs.pylonsproject.org/projects/pyramid_cookbook/dev/sqla.html Seems like basically the same idea except that I'm using the standard thread-local Session factory. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: a few more pyramid questions
To be clear:
This works:
@action(renderer='/test_a.mako')
def test_a1(self):
return {'project':'myapp'}
@action(renderer='/test_b.mako')
def test_b1(self):
return {'project':'myapp'}
def test_c1(self):
return render_to_response('/test_b.mako', self.test_b1(),
request=self.request)
But this doesnt:
@action(renderer='/test_a.mako')
def test_a2(self):
return {'project':'myapp'}
@action(renderer='/test_b.mako')
def test_b2(self):
return HTTPFound(location='/account/login')
def test_c2(self):
return render_to_response('/account/test_b.mako',
self.test_b2(), request=self.request)
Based on this pattern, I don't think it would be possible to migrate
any of my Pylons apps to Pyramid -- this behavior would require a
substantial rewrite of most controllers.
1- The way redirects / 404s are currently implemented creates a need
for additional logic in a dispatching function ( the results would
need to be tested, not handled by the framework )
2- There looks to be a duplication in labor - a call to a dispatched
function would also require noting the template as well. So instead
of just noting the template at the function, you're also noting it at
anything that dispatches it.

Re: Form handling in Pyramid
personally, think it would be best to decouple the moving parts as much as possible to me, there is : html form creation - great if this is baked-in, but it shouldn't be required form validation - i think formencode is fine, but i often use it as a first-pass and then handle things in my controllers too form submission - validation is only a portion of submission. what is triggering the validation ? what happens when its a success ? how about a failure ? anything else could/should be a module that plugs into the forms. the old @validate had some issues, but could have been extended into something more powerful. at least in my usage i was able to separate out the various phases and provide hooks back into it. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: some thoughts on pyramid
I've forked Mike's pyramid_sqla , and have been extending the templates to be more familiar to pylons users. Namely: 1- making the app structure seem more like a more mature pylons 1.0 app 2- added some reference functions around form submissions , beaker session usage , etc 3- integrated some routines and designs from the pylonshq source code ideally, someone would be able to create a new project and see a reference of how to do most things right in the source. They only need to delete a few lines and files in order to get going on their on stuff. perhaps this template should have a different name -- but it seemed to me like a mechanism was needed so people could get up running in a manner of minutes, without reading a ton of docs.

like this in the 'handlers':

does this mean you can't switch out the templates in these handler

Took a lot of combing to find. It was kind of hidden under some text on the Pyramid intro. Would be great to see that in another tool tip style text-treatment like the item above it. Will be going through it tonight. When Pylons was created in 2005, every framework had to be like Rails and MVC in order to succeed. Yet Django became the most-used Python framework in spite of being MV rather than MVC. The main issue for developers is ignorant managers who say It must be Django (or Rails/PHP/Java) -- without knowing anything about these technologies, just that these are the popular buzzwords. It's much less common to hear Must be MVC. For developers who can choose their own framework, again they are swayed more by these Django/Rails/PHP/Java buzzwords than by MVC. So Pyramid's most direct competitor nowadays is Django, not MVC. I know that too well and can give a few perspectives: I took over as Acting CTO at TheDailyBeast.com a few months ago. My predecessor committed the org down a Rails path that I needed to finish up ( legacy on php ). Then we merged with Newsweek. I was in meetings with the rest of the management teams nonstop for months. When execs hear words like typical/standard MVC , its a few points in your favor. When there are words like MV or just like Django - it falls on deaf ears. I do A LOT of consulting with startups and ad agencies in the NYC area. 9/10 times they have a MVC framework or experience. it's not just Rails, but there's also: CakePHP, Symfony, CodeIgnighter, Kohana, etc. Django can look slightly alien to folks because of the paradigms it's chosen, but its also got some familiar elements. Pyramid has less of the familiar elements, because like Pylons its more for power users and engineers than webapp developers. Only 1/10 people I meet would even be interested in Pylons; for the rest - they're looking for familiar ground. The developers went back and forth on this but in the end went with single modules. i'd really suggest revisiting this. showing multiple files gives a clear idea and example how to scale. programmers looking at multiple files can more easily see how to collapse into a single file, than looking at a single and trying to figure out if there's any special stuff needed to use multiple files in the module.

some thoughts on pyramid
I spent some time today with Pyramid. It was a bit of a rollercoaster -- at times I was very excited, at others very stressed. i figured i'd share my thoughts here for the maintainers. 1. on setting up an app, there were no instructions on how to setup for a postgres 'url' in sqlalchemy ; in fact - there was nothing in there regarding this setup. i pulled it out of an existing project; one could probably look at pylons 1.0 (not pyramid) docs. 2. i assume this is part of the template designed to show how to do stuff... however creating the initial 'models' table, with a sample entry, is misleading and not clear. i'd suggest changing it to sample_model or something that is very clearly not needed for the application. 3. i haven't figured out yet if its possible to handle multiple db connections in pyramid. in pylons i have sqlalchemy.write.url and sqlalchemy.read.url and handle multiple databases due to master/ slave clustering. in order to get widespread appeal, something like this needs to be very apparent and easy to do - Rails accomplishes this in a few lines of configs. 4. i'm not sold on the MV design. personally, I think it was risky departing from MVC, which has become the de facto standard and super familiar for developers across the web. django has had issues selling people on their MVT , and its just an uphill battle. i'm sure it has many advantages, i'm just speaking from a 'marketing ' view. 5. the default application template should really generate a multiple views models structure. most people i've worked with strive very hard to keep the entirety of their models/views from being a single file. 6. also on the migration point, it would be good to discuss sqlalchemy reflection. The code looks solid, and I understand the rationale behind a lot of design choices... but from an adoption view, i think there's a lot of work to be done. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Pyramid for Pylons users guide

Re: Pylons for Facebook apps
i tried it a while back, and then gave up. i don't think its worth it, because facebook has changed the way the apps work so many damn times i think you'd be better off just using one of the many full-featured, mature, has-tons-of-people-maintaining-it php libraries that are out there , and let that handle all the integration crap. then your pylons app can just sit on the site, and do what it needs to do regardless of facebook. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Hiring Pylons Devs in NYC
Hi all- One of the startups that I'm working with will be starting a round of hiring in the next 2-6 weeks. We're in NYC. I'm effectively the director of product engineering... or something like that. The CTO is focused on RD, so I'm dually the product manager and building out the development engineering teams. There's a full posting here: http://jobs.nytm.org/job/multiple-developer-engineering-opportunities-new-york-ny-5ad6b2edb5/?d=1source=site_home The nitty gritty you'll care about before clicking the above: - Our webapps are being rebuilt on Pylons Postgres , using a microframework that started out at FindMeOn and has been used at ArtWeLove and a few other projects. They were php+mysql until i yelled profusely. - I'm projecting that we're going to have serious scaling issues in 3 months, based on some partnership contracts that we're working on - We're looking at building out a service oriented architecture -- the main user interface will be in Pylons and we'll store transactional data in Postgres... but we're going to need some fancy shit behind-the- scenes as well as a decent API for partners. So in addition to Pylons folks, I'm also on the lookout for people with experience/aptitude for Erlang, Scala/Lift, and custom C/C++ servers, as well as nosql experience. - I'm looking for folks at all levels. I'd definitely love some folks who are much smarter and better than me on the team, and we're totally open to smart folks with great aptitude that don't have much experience. There's more info on the link above. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: FormEncode inadequate?
I use FormEncode very happily... along with a custom solution.
1. For multiple-step logic, I use multiple FormEncode forms.
2. For advanced formatting, my stuff looks like this:
def form(self):
if request.params.get('m') == 'submit':
return self._form__submit()
return self._form__print()
def _form__print():
return render('form.mako')
@custom_validate(form='_form__print')
def _form__submit(self):
try:
if i_encounter_error:
raise GetPost_Form_Error(value)
except GetPost_Form_Error, e:
tweak_c_or_form_results_with( e.value )
return form_reprint( self, '_form__print' )
except:
raise
return 'yay'
that lets me handle a lot of situations. if i'm dealing with
formatting multiple error fields, i just populate a dict with errors
and raise at the end.

Re: application deployment question about nginx and pylons
I'm of this school of thought: if you're doing anything with moderate to high traffic, you should be running NGINX on port 80 , with a proxypass to something else. What you proxypass to, however, is up to you. 1- paster 2- wsgi 3- apache the important thing is to get Apache off of port 80 , its really just not a great performer. you *especially* don't want to run apache on port 80 if you're using a single apache configuration. the mod_perl folks did the math and wrote a chapter or two about it, which may have wound up online... it was called vanilla apache + mod perl or something like that. you basically want the lightest and leanest server running on port 80 as possible (nginx, or a stripped down apache with as few DSOs loaded as possible) . you can then proxy back to other servers as needed. if you decided to stay apache, you DEFINITELY want to run a vanilla instance on port80 to handle static files and proxy back. the reasons for this are twofold: 1- IIRC, a stripped down apache process is 500k or so of memory; a mod_* will grow to 3-5MB, and then compile in your application code and allocated/reserved memory... which often ends up at 20-30MB per process. if you run your app on port 80, both static files and dynamic content will be served by these apache processes - which means you'll tie up the 20-30mb processes with tasks a 500k one could do. if you profile your app correctly, you can find the right types of servers to run that will easily allow you to increase your throughput by 10-20x -- if not more -- just by smarter resource allocation. 2- if a client is slow, or drops a connection without being detected, your dynamic apache ( or anything else ) just sits there slwly serving a file until a timeout is reached. if you put a 'vanilla' server on port 80, the dynamic server instantly returns the result to it... and it can handle the timeout/slowdown issues... freeing up the memory and processor for the dynamic server to process another request. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Pylons hosting on a VPS (memory usage)
i'm running pylons apps on a few VPS my issues have been this: - the database takes up a lot of ram - the search engine takes up a lot of ram pylons app performance has been better as more ram is tossed in. if you're running a DB like postgres or mysql on the same vps, i would probably use 512mb ram as a minimum... 256 could work. if you're running anything like solr/lucene as well, i'd defintely consider 512 a minimum in terms of the apache issues indicated above -- were they on the master or child processes ? you should be able to mitigate that behavior on the children by tweaking max_requests also, as i remember from my mod_perl days, apache doesn't like to free memory on a restart. you need to explicitly stop then start. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

any good references / best practices for Test Driven Design and Integrated Testing with Pylons ?
I really do love the fact that Pylons offers the unit tests ; however as others have mentioned - they can be really difficult to use when session based data is concerned ( or when forms require access to Globals ,etc etc ) I pretty much stopped using them a while back, and just started doing everything with selenium. I'd like to transition back into using them though - so i can have automated testing and deployment.

Re: which is the best ORM recommended?
for what its worth... I find ORM useful for three things: - inserts of new records - updates of single records - displaying data in templates i find ORM a hassle on larger items. i'd much rather write SQL myself , that i know is optimized and i have control over. A great middle ground which I've found, is that in many instances an ORM allows you to supply the raw SQL, or you can do manual SQL queries and 'bless' ( to borrow from Perl ) the results into an object. With situations like this, you can get the benefit in the View/templates that the ORM provides, while keeping your model and controller much more sane and optimized. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

looping sqlalchemy attributes
my code is still running on sqlalchemy .48, so if this has been
addressed in future versions - let me know!
lets say i have a one-to-many sqlalchemy relation, and loop an
attribute called items:
def cleanup( cart ):
for item in cart.items:
if item.qty == 0 :
self.dbSession('write').delete( item )
once i call cleanup(cart) , how can i ensure that looping through
cart.items will not bring up the deleted items ?
if i loop through the cart.items again, I'll have None types where I
deleted
i found that if i do a flush() and expire() , i can avoid this
for item in cart.items:
...
self.dbSession('write').flush()
self.dbSession('write').expire(cart)
Is this the best way to handle the situation ? is there something
better ?

Re: Validating a select box

unexpected behavior of request.params after validate ; is this intentional of webob (not @validate)?
i spent the past 3 hours going through my own validate code, and the
original pylons that i forked off of, trying to figure out why params
is always empty on a form error.
i finally tracked down the issue.
@validate has this line, so that the form can be re-run as a GET with
htmlfill args:
request.environ['REQUEST_METHOD']= 'GET'
and this is the weird behavior:
once this is set, it appears to be impossible to access any POST vars
via :
request.params.get(var) # makes sense
request.params.POST(var) # empty
request.params.POST # empty
however if i run this:
request.environ['REQUEST_METHOD']= 'POST'
then all my data is accessible again.
this seems to happen because of this line in webob:
if self.method not in ('POST', 'PUT'):
return NoVars('Not a form request')
i'm not sure if this was intentional , or some sort of optimization.

Re: @validate revisited, JSON support, content negotiation
ah, interesting -- so the validation becomes a function of the controller. i'd like to make a suggestion to your then. i have an arg to validate called gatekeeper , which is enabled as True by default ( along with post_only ) In conjunction with one another, gatekeeper just makes sure that if you GET a form that is post_only ( or: not on_get ) , you automatically raise an error. in the original pylons distro, it was possible to GET a post_only form and have things not work out the way you would want them to. personally i thought it opened the door to security issues, others disagreed. ``gatekeeper`` Default True. Boolean to raise an error on form submission if not complete. the code in mine/patch to distribution is : if request.environ['REQUEST_METHOD'] == 'GET' and not on_get: if gatekeeper: ControllerInstance.osn_form.is_error= True raise ValidationStop() I'm not sure how it would work on yours. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Pylons and images from database
if you store things on the filesystem, you'll need to use a hashing algorithm to bucket it effectively -- filesystems don't like too many files in a directory. you don't need to rename the file to a hash -- you could just store that in the db -- but I'd advise renaming the file to a hash, because then you can write a regex rule or something super simple to serve it. ie: a file named aabbccddeeff.jpg would end up as aa/bb/cc/dd/ee/ff/ aabbccddeeff.jpg ; a rewrite rule could easily map requests for http:/ img .site.com/aabbccddeeff.jpg to that folder ; you wouldn't have to include the actual filepath. in my years i've learned a few things: 1- hashing to md5 base 16(hex) is fine. if you do 3 chars per directory, you have 4096 buckets in each level; going 3 deep gives you a ton of directories. if you do base32, you can do 2 chars per directory, and have 1024 in each level. a couple of filesystems start to degrade around 1k and 10k files - so this could improve performance. 2- if you bucket items by numeric id, bucket backwards. ie: 123456789 - 9/8/7/6/5/4/3/2/1/123456789. there's a math law about this, i can't remember the title, but basically points out that you'll round- robin evenly if you bucket from the back, but you'll have a new bucket every power-of-10 if you bucket forwards..

Re: Writing a web app as a series of plugins
I tried to do this before, and gave up. It became WAY too confusing and difficult to manage as WSGI components. What I ended up doing is creating a single WSGI component to 'plugin' and bootstrap some special variables into 'c'. I then created a series of Libraries that offer functions and basic controllers.

Re: Do your models handle all the data logic?
I use PostgreSQL exclusively too, and rely on tons of constraints within the db - from unique indexes built through functions, to actual functions themselves. I still, pretty much, always query the db to check for a duplicate value or possible constraint violation. 1- It's easier than parsing errors. plus you don't have to continually flush() or save() to trap the error. 2- There's really not much of a performance hit on any site i've ever worked on. In terms of the MVC debate - I've gone through the entire array of options that Mike Orr has illustrated ( though not all in Pylons ). I've had Models that have most of the logic, and the Controllers just call them... I've had Models that have no logic... and I've had Models that wrap ORMs as an abstraction layer, so I can use multiple backends (or ORMs ) easily. After years of struggle, I've ended up with this approach: - I put 'search' and 'new' functions in the model. I also put 'render' functions too ( like model.F_url() to display a url ) - If more than one controller needs to do similar operations on the model, I break it out into a helper method and stash it as a library function. The problem I encountered with putting too much logic in the models, is that MANY of my models were highly interrelated with other models. From a maintenance and testing standpoint, this created too many headaches. I really don't like 'horizontal' interactions of models creating and modifying one another. So many issues arose. Examples that caused issues for me were Group creates / controls Members ( and vice versa ); or if Account creates AccountAsset or ApiKey. I can't recall if I had the most issues with Python or Perl or something else... but with horizontal interaction within the model, I always had issues of inclusion order / dependencies / etc. So I've found it simpler that each Model is only concerned with a representation of One member of its own class -- and that a Controller , or helper function , handles the interrelation of all of them. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Caching all but 1 variable.

Someone in IRC said write a wrapper, but having a hard time wrapping
my head around this, since the data I need to cache is all in the

the cache render function would run.
I do almost the same thing in a few places on ArtWeLove.com
The two techniques I use:
- In most instances, Pylons writes a .php file. Yeah, I hate that
damn language too -- but running php through nginx+fcgi with a couple
of optimizations makes it considerably faster than Pylons. Nginx just
knows which directories to serve as php, and which to not. If there
are a handful of variables , i'll often have pylons write out a php
file that is just a dict/array of the variables in php.
- In some instances, I just use beaker caching. this is confusing to
explain, so i'll try to illustrate with code that handles 1 'heavy db
call' fragment. In practice, our splash page has 3 zones that we do
this to.
index-fragment-a.mako
% for item in dbcall: do stuff
index.mako
%inherit file=/@site-template.mako/
${h.literal(c.rendered_fragment__a)}
splash.py
def splash(self):
page_cache= cache.get_cache('awl.page',cache_type='memory')
c.rendered_fragment__a = page_cache.get_value( 'splash:a',
createfunc= self._splash_generate_fragment_a ,
expiretime=g.awl_cache_expiry_page )
c.code= CODE
return render ('/index.mako')
def _splash_generate_fragment_a(self):
self._dbSessionSetup('read')
lots of db calls
return render ('/index-fragment-a.mako')
does that make sense?
There's a third technique you could do as well -- you could just
render the page and store in beaker , and either have that template
generate a mako template ( by escaping certain interpolation stuff )
or just some raw html with a string like CODE# then do
def splash(self):
page_cache= cache.get_cache()
template= page_cache.get_value( 'splash:a', createfunc=
self._generate )
template= template.replace( 'CODE', code )
return template
i think there's a way to render() on a string too (instead of a file )
so it could be...
c.code= CODE
return render( string_template= template )
i have no idea what the params would be -- i made up
string_template... but i'm pretty sure i've seen that in the
templating source code.

Why doesn't it render foo? #continue doing stuff However this code prints 'in foo' then 'what am I doing here?' and I think its because the request cycle is getting things confused (kind of jumping into another one before finishing first). While perhaps not a bug (but I'm not sure of that, it is indeterminate what will happen), it could be handled better and would be if I could throw out the response so far and restart with the new method (be more performant as well). self.foo() does not dispatch a new request, it merely calls the foo() method of self inline the request cycle is not getting confused. the dispatcher called self.bar() , and that is it. self is just a python object. if you want to return the output of foo, the code should be def bar(self): if 'v' not in request.params: return self.foo() print 'what am i doing here?' v= request.params['v'] #continue doing stuff Why doesn't it render foo? the original code did render foo. however it did nothing with the output. calling self.foo() doesn't create a new request / re-dispatch , it just runs foo() like any other python object woud. if you want to do that, you need to redirect or subrequest. in order to foo() and stop and return the output of foo() to the browser, you would call return self.foo() Look through my first example, and Graham's later example -- which both addressed this pattern. -- You received this message because you are subscribed to the Google Groups pylons-discuss group.
