pylons

I have Eclipse setup with PyDev and love being able to debug my scripts/apps. I've just started playing around with Pylons and was wondering if there is a way to start up the paster server through Eclipse so I can debug my webapp? Create a new launch configuration (Python Run) Main tab Use paster-script.py as main module (you can find it in the Scripts sub-directory in your python installation directory) Don't forget to add the root folder of your application in the PYTHONPATH zone Arguments Set the base directory to the root folder also. As Program Arguments use "serve development.ini" (or

I am giving Pylons a try with SQLAlchemy, and I love it, there is just one thing, is it possible to print out the raw SQL CREATE TABLE data generated from Table().create() before it's executed? Antoine Leclair from sqlalchemy.schema import CreateTable print(CreateTable(table)) If you are using declarative syntax: print(CreateTable(Model.__table__)) Update: Since I have the accepted answer and there is important information in klenwell answer , I'll also add it here. You can get the SQL for your specific database (MySQL, Postgresql, etc.) by compiling with your engine. print(CreateTable(Model._

I'm programming a web application using sqlalchemy. Everything was smooth during the first phase of development when the site was not in production. I could easily change the database schema by simply deleting the old sqlite database and creating a new one from scratch. Now the site is in production and I need to preserve the data, but I still want to keep my original development speed by easily converting the database to the new schema. So let's say that I have model.py at revision 50 and model.py a revision 75, describing the schema of the database. Between those two schema most changes are

We have several Python 2.6 applications running on Linux. Some of them are Pylons web applications, others are simply long-running processes that we run from the command line using nohup . We're also using virtualenv , both in development and in production. What is the best way to deploy these applications to a production server? In development we simply get the source tree into any directory, set up a virtualenv and run - easy enough. We could do the same in production and perhaps that really is the most practical solution, but it just feels a bit wrong to run svn update in production. We've

How do i check if a user has a permission in pyramid. For example, I want to show some HTML only if a user has some permission, but have the view available for everybody. The usual method is: from pyramid.security import has_permission has_permission('view', someresource, request) See also http://docs.pylonsproject.org/projects/pyramid/1.0/narr/security.html#debugging-imperative-authorization-failures and http://docs.pylonsproject.org/projects/pyramid/1.0/api/security.html#pyramid.security.has_permission 来源： https://stackoverflow.com/questions/4916127/check-if-a-user-has-a-permission-in

I would like to use autoload to use an existings database. I know how to do it without declarative syntax (model/_ init _.py): def init_model(engine): """Call me before using any of the tables or classes in the model""" t_events = Table('events', Base.metadata, schema='events', autoload=True, autoload_with=engine) orm.mapper(Event, t_events) Session.configure(bind=engine) class Event(object): pass This works fine, but I would like to use declarative syntax: class Event(Base): __tablename__ = 'events' __table_args__ = {'schema': 'events', 'autoload': True} Unfortunately, this way I get:
