Why is my log level not being used when using loadapp from paste.deploy?

阅读更多关于 Why is my log level not being used when using loadapp from paste.deploy?

I want to temporailiy turn on debug messages in a production pyramid web project so I adjusted the production.ini file, pushed it to Heroku and saw only error and warn level messages. So I thought, that seems odd since if I start the pyramid application like the following on my local PC I get all the log level messages. env/bin/pserve production.ini OK, so that's not exactly how it runs on Heroku, it is actually run from a little bit of python that looks like this (in a file called runapp.py ): import os from paste.deploy import loadapp from waitress import serve if __name__ == "__main__":

Chameleon templates for javascript files?

阅读更多关于 Chameleon templates for javascript files?

I am developing a simple pyramid application where I am using JQuery to do AJAX requests. I have until now had my javascript code within my chameleon templates. Now I want to extract my javascript into another location (e.g. as static resources).

How to use template inheritance with Chameleon?

阅读更多关于 How to use template inheritance with Chameleon?

I am using latest Pyramid to build a web app. Somehow we have started using Chameleon as the template engine. I have used Mako before and it was extremely simple to create a base template. Is this possible with chameleon as well? I have tried to look through the docs but I can not seem to find an easy solution. With Chameleon >= 2.7.0 you can use the "load" TALES expression. Example: main.pt: <html> <head> <div metal:define-slot="head"></div> </head> <body> <ul id="menu"> <li><a href="">Item 1</a></li> <li><a href="">Item 2</a></li> <li><a href="">Item 3</a></li> </ul> <div metal:define-slot=

How do I split models.py into different files for different models in Pyramid?

阅读更多关于 How do I split models.py into different files for different models in Pyramid?

问题 I am new to pyramid and have been struggling to make some changes to my project. I am trying to split my models/Classes into individual files instead of a single models.py file. In order to do so I have removed the old models.py and created a models folder with __init__.py file along with one file for each class. In __init__.py I imported the class by using from .Foo import Foo . This makes the views work correctly and they can initialize an object. But running the initializedb script does

SQLAlchemy - Getting a list of tables

阅读更多关于 SQLAlchemy - Getting a list of tables

问题 I couldn't find any information about this in the documentation, but how can I get a list of tables created in SQLAlchemy? I used the class method to create the tables. 回答1: All of the tables are collected in the tables attribute of the SQLAlchemy MetaData object. To get a list of the names of those tables: >>> metadata.tables.keys() ['posts', 'comments', 'users'] If you're using the declarative extension, then you probably aren't managing the metadata yourself. Fortunately, the metadata is

Multiple domains and subdomains on a single Pyramid instance

阅读更多关于 Multiple domains and subdomains on a single Pyramid instance

I'm looking to have multiple domains and subdomains on a single Pyramid instance. However, I can't seem to find any documentation on it. The last question referred to a glossary with very little information and no examples. Do any of you have any examples or can direct me to better documentation? Pyramid is just a WSGI application. This means it's dependent on the HTTP_HOST environ key (set by the Host header) to determine the host of the application. It's all relative. Point-being that Pyramid has no restrictions on what it can accept, thus the world is your oyster and you can set it up to
