python pylons pyramid
What problems can I have if I will use python 2.7 instead python 2.6 for my pylons/pyramid projects? Before I use python 2.6 on my ubuntu 10.04 but now I have ubuntu 11.04 on my laptop with python 2.7.

python wsgi pyramid
INTROI’ve recently switched to Python, after about 10 years of PHP development and habits.Eg. in Symfony2, every request to server (Apache for instance) has to load eg. container class and instantiate it, to construct the “rest” of the objects.As far as I understand (I hope) Python’s WSGI env, an app is created once, and until that app closes, every request just calls methods/functions.This means that I can have eg. one instance of some class, that can be accessed every time, request is dispatch

python plugins pyramid
I’d like to know how to edit pyramid registry at runtime. Well i’m not so sure exactly what I have to edit. I know I can extend pyramid with config.include(…). But once config.make_wsgi_app() is called, there seems to be no way to add routes or new mako directories. Any change to the registery in threadlocals or settings have no effect on how the app behave. My goal is to add plugin at runtime. Here’s a use case. Someone install my appserver running pyramid…then install some pluginspip insta

python sqlalchemy pyramid paster
I’ve defined a new Column type called File, which should let me store only the file name in the database. Then I would store the actual file in the file system at root+subfolder+name.File(root, subfolder=””, max_length=100, **kwargs)The problem I’m having is that I’d like to define the root in a PasteDeploy config file. How do I define this at runtime so I can access the configuration?

In pyramid, I need to render my templates according to different runtime environments — enable google analytics, use minified code, etc. (when in production). Is there an easy way to find out the current environment — perhaps an existing flag to find out which ini file was used?

python crash paste pyramid chameleon
I have a Pyramid application that uses Chameleon as its template engine. I have one (quite large, but I have had larger) template that will just not work. Whenever I try to render it to return as a view, paste server development.ini crashes miserably without any errors (Mac OS X’s terminal tells me “bus error”). When I run the exact same code on my server with apache and mod_wsgi, everything works great. How do I even start figuring out whats wrong?

python views pyramid error-logging
Task: When an error occurs in one of my views I need to show a custom error view. The error type does not matter.I tried to override all exceptions by registring a view for all exceptions, like this:<viewcontext=”Exception”renderer=”server_error.pt”/>It worked good. All exceptions were showing my view. But the problem was that those errors stopped logging. Of cource I can do something like logger.error(traceback) in my error view, but this is a dumb idea.How can I register a view for all e

python reflection sqlalchemy pyramid
I am currently working on a pyramid system that uses sqlalchemy.This system will include a model (let’s call it Base) that is stored in a database table. This model should be extensible by the user on runtime. Basically, the user sould be able to subclass the Base and create a new model (let’s call this one ‘Child’). Childs should be stored in another database table.All examples available seem to handle database reflection on a predefined model. What would be the best way to generate complete mo

pyramid mako
I’m using Pyramid 1.3 with Mako Templating. I have a view with a method called “create” that returns an empty dictionary to a template. I intend to use the same “create.mako” template for both creating and editing. I’ve put the context variable like such in my input fields:<input type=”text” id=”nameInput” value=”${content[‘name’]}” />The problem with this is that I get errors like below when I try to load the create method:<input id=”nameInput” value=”${content[‘name’]}” type=”text”
