  • google app engine persistent globals

    - by Joey
    Hi, I'm looking for a way to keep the equivalent of persistent global variables in app engine (python). What I'm doing is creating a global kind that I initialize once (i.e. when I reset all my database objects when I'm testing). I have things in there like global counters, or the next id to assign certain kinds I create. Is this a decent way to do this sort of thing or is there generally another approach that is used?

  • JSON serialization of Google App Engine models

    - by user111677
    I've been search for quite a while with no success. My project isn't using Django, is there a simple way to serialize App Engine models (google.appengine.ext.db.Model) into JSON or do I need to write my own serializer? My model class is fairly simple. For instance: class Photo(db.Model): filename = db.StringProperty() title = db.StringProperty() description = db.StringProperty(multiline=True) date_taken = db.DateTimeProperty() date_uploaded = db.DateTimeProperty(auto_now_add=True) album = db.ReferenceProperty(Album, collection_name='photo') Thanks in advance.

  • Game engine with python scripting?

    - by Kayle
    Looking to put together a 3D side-scrolling action platformer. Since this is my first time trying to put together a non-simple adventure game, I'm at a loss for which engine to consider. I would prefer one that supports scripting in python, since that's my primary language. Without tight controls, the game will suck... so speed is a priority. Cross-platform is also important to me. Any suggestions?

  • 3d engine with telnet access

    - by zaf
    Does anyone know of a open source 3d engine which can be operated via telnet? What I'm looking for is scripting via a socket connection. To allow for world creation and/or camera movement. Does anybody know of any that has this built in or very, very easy to add as a plugin or script? The platform is not crucial.

  • Getting logging.debug() to work on Google App Engine/Python

    - by brainjam
    I'm just getting started on building a Python app for Google App Engine. In the localhost environment I'm trying to send debug info to the GoogleAppEngineLauncher Log Console via logging.debug(), but it isn't showing up. However, anything sent through, say, logging.info() or logging.error() does show up. I've tried a logging.basicConfig(level=logging.DEBUG) before the logging.debug(), but to no avail. What am I missing?

  • Facebook connect on Google App Engine with Django Patch

    - by yoav.aviram
    We are building a website on Google App Engine, using django patch. We would like to use Facebook connect for two purposes: Authenticate users. Access user's social data. Searching for a solution in the usual places (google, FB, SO) brigs up a lot of noise, many partial solutions and no clear answer. So the question is this: does anyone has a clear working solution? maybe even a recipe? Thanks.

  • Refactored App Engine project - now Eclipse is infinitely building the project without end

    - by Yog
    I renamed some files in my App Engine project and refactored code, changing references to variables. Everything seemed fine until I changed the references in the web.xml for the project. Then I got a complaint about some error with the DataNucleus enhancer and now the project build process is stuck at 22%. I tried stopping Eclipse and restarting but the build process keeps hanging. Any tips on how to clean out whatever it's getting stuck on?

    What is the best way to save a user profile with Google App Engine (Python) ? What I did to solve this problem is create another Model, with a UserProperty, but requesting the profile from the user I have to do something like this: if user: profile = Profile.all().filter('user =', user).fetch(1) if profile: property = s.get().property Any ideas?

  • Extract text from PDF (google app engine)

    - by Miroslav Bajtoš
    Is there any free Java library for extracting text from PDF, that is compatible with Google Application Engine? I've read about PDFJet, but it can't read PDF, can it? Is there perhaps other way how to extract text from PDF? I tried http://www.pdfdownload.org/, unfortunately they don't handle non-English characters correctly.

  • Google App Engine with local Django 1.1 gets Intermittent Failures

    - by Jon Watte
    I'm using the Windows Launcher development environment for Google App Engine. I have downloaded Django 1.1.2 source, and un-tarrred the "django" subdirectory to live within my application directory (a peer of app.yaml) At the top of each .py source file, I do this: import settings import os os.environ["DJANGO_SETTINGS_MODULE"] = 'settings' In my file settings.py (which lives at the root of the app directory, as well), I do this: DEBUG = True TEMPLATE_DIRS = ('html') INSTALLED_APPS = ('filters') import os os.environ["DJANGO_SETTINGS_MODULE"] = 'settings' from google.appengine.dist import use_library use_library('django', '1.1') from django.template import loader Yes, this looks a bit like overkill, doesn't it? I only use django.template. I don't explicitly use any other part of django. However, intermittently I get one of two errors: 1) Django complains that DJANGO_SETTINGS_MODULE is not defined. 2) Django complains that common.html (a template I'm extending in other templates) doesn't exist. 95% of the time, these errors are not encountered, and they randomly just start happening. Once in that state, the local server seems "wedged" and re-booting it generally fixes it. What's causing this to happen, and what can I do about it? How can I even debug it? Here is the traceback from the error: Traceback (most recent call last): File "C:\code\kwbudget\edit_budget.py", line 34, in get self.response.out.write(t.render(template.Context(values))) File "C:\code\kwbudget\django\template\__init__.py", line 165, in render return self.nodelist.render(context) File "C:\code\kwbudget\django\template\__init__.py", line 784, in render bits.append(self.render_node(node, context)) File "C:\code\kwbudget\django\template\__init__.py", line 797, in render_node return node.render(context) File "C:\code\kwbudget\django\template\loader_tags.py", line 71, in render compiled_parent = self.get_parent(context) File "C:\code\kwbudget\django\template\loader_tags.py", line 66, in get_parent raise TemplateSyntaxError, "Template %r cannot be extended, because it doesn't exist" % parent TemplateSyntaxError: Template u'common.html' cannot be extended, because it doesn't exist And edit_budget.py starts with exactly the lines that I included up top. All templates live in a directory named "html" in my root directory, and "html/common.html" exists. I know the template engine finds them, because I start out with "html/edit_budget.html" which extends common.html. It looks as if the settings module somehow isn't applied (because that's what adds html to the search path for templates).
