[web2py] Problem streaming videos in OS X
When I upload a video file (in MPEG4 format) to the static area, only the first several seconds will play in the video control appearing on the page. This happens whether I use an auth.wiki() provisioned page, or if I simply embed a ... tag on the Welcome index page. I've tried both video files I've created, as well as some simply downloaded from YouTube and uploaded into the static area from the "designing" admin page. On the wiki generated page, I can put in a URL for an external site and it streams perfectly. However, when I looked at the page source, that link was using an tag rather than a tag. The same behavior is exhibited whether I use Chrome or Safari (since Firefox has known issues with MPEG4 files), and whether or not I'm using the server only on "localhost" or within my lan from another machine. This is the only problem I'm having - and it's a rather serious one, since the project I'm working on uses many, many videos. It's a deep-dive self-guided technical presentation that will be used by a large development team. At this point, I've made no mods to any code at all, with the exception of putting the URL into the wiki page (as: http://HOSTNAME/MyTest/static/testFile.mp4 ) or embedding the same filename as the src file in a tag in the default_index.html page for the Welcome app. I'm running web2py Version 2.5.1-stable+timestamp.2013.06.06.15.39.19 on an iMac with OS X 10.8.4. The installation was simply to unzip the download into the Applications folder. I'm starting it from a shell using the command line "python web2py.py" so I can see any possible output. I'm using python 2.7.2. Thanks in advance for any help. -- --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] Re: Load content from a text file
Do you need to use a text file as an intermediary? I created a similar app for my pedal-powered laptop (described at www.pedalpc.com) where a function is called in the controller that reads/writes the serial port and returns the data as JSON which just updates the necessary data in the page in the browser. This method assumes the client has the processing power to handle updating the page via JSON...

[web2py] Re: An architectural strategy for a website - I'd like comments
Thanks guys!
So for next level strategy I will:
1) Determine and cache all queries and calculations that are non user
spefic (e.g. ranking of all participants)
- This can be done either with cached select(), or using
cache.ram/memcache/redis directly
- These could be done in a model level to make sure that they are updated
regularly or use a cron/scheduler to do that in a background
2) Make session specific calculations and queries lazy and cache those that
are required to be done multiple times in a session
- This can be done with @cache_property and/or storing results in a session
variable (e.g. participant ranking in different competitions)
3) Use iterator/generator with those methods/functions that require only
end result and most likely only once
- These could be also stored in a session for reuse if necessary
And of course it's a good idea to analyze code and decide the indexing of
the database tables based on what is used heaviest.
I think it's easier to get the right strategy now when the code is simple,
than later. Although I find Python flexible to change architecture also
later.

Hi,
After learning Python and web2py deeper, I've restructured my web2py
application so that all functions and data are now in classes with lazy
methods in my own module. The lazy property class turns any method into a
"cached attribute", thus I can make a db query that returns rows and if it
is called again it uses the previous result.
What this has allowed me to do, is to clean practically all code in my
controller as the logic and variables are in a class. Now I just pass the
class to the view and the view prints the "attributes" directly without
separate call and saving to dict. I've read that some don't like any logic
in the view, but that's unavoidable as in the view you need to print stuff
depending who the user is and is he logged in or not.
I'd like your opinions and comments on my strategy. Here are few
simplified examples from my code:
Module:
class MyClass(object):
def __init__(self):
self.db = current.db
@cached_property
def all_participants(self):
return self.db(self.db.participant.id>0).select()
class MyClassParticipant(MyClass):
"Inherits base class"
def __init__(self, auth_user_id=None):
self.auth_user_id = auth_user_id
super(MyClassParticipant, self).__init__()
@cached_property
def participant_stats(self):
return
self.db(self.db.participant.auth_user_id==self.auth_user_id).select()
Controller:
def index():
if auth.user:
xclassinstance =
module.MyClassParticipant(auth_user_id=auth.user_id)
else:
xclassinstance = module.MyClass()
return dict(xclassinstance=xclassinstance)
View:
{{if auth.user:}}
Your ranking is {{=xclassinstance.participant_stats.ranking}}
Rankings of all participants
{{for participant in xclassinstance.all_participants:}}
{{=participant.name}} ranking is {{=participant.ranking}}

[web2py] making true copy of HTML helpers
I discovered one way to make a true copy of some list of HTML helpers. I
would like to know if there are other more, web2py / pythonic ways to do
it. So for instance:
form = SQLFORM.factory()
trs = form.elements('')
trs_true_copy = map(lambda x: TAG(x.xml()),trs)
which works just fine, though it seems a bit overkill having to serialize
and deserialize to make a true copy.

[web2py] Re: making true copy of HTML helpers
there's a conceptual problem with your question either you want to save
a list of HTML helpers or you need to save a full-blown form. Of course you
serializing only the HTML part of the form won't get you form.vars,
form.accepts(), etc etc.
I'm curious though, what and why do you need it?

Hello, only one max two clients at a time will access this page. I don't even see why two clients would be accesing this page if not a supervisor wants to check on the progress of an worker.

The app stores also everything in the database but I thought it would be more efficient for this page to get the info from an text file. There will be many other pages that will be using mobile jquery with an normal menu that reads data from the database, but this one special page will be just a blank page showing the content of the file if I can't find out how to reload just the part of the page that shows the text file.

returns me in the format of the translation file("%d/%m/%Y"), but when use
like this to do the search, it returns nothing or something not expected.
But if i mannually change the format from the search on the sqlform.grid to
"%Y/%m/%d" it works out. How do to the sqlform.grid recognize the format
that i want to use on the search("%d/%m/%Y") ?

[web2py] Re: urlify - no char mapping
It works great, but I'm not getting "ł" character mapped using
IS_SLUG.urlify(string). How do I make sure all special characters (e.g.
latin ones) get mapped? Do I need to use a custom mapping dictionary or
there's maybe an easier, built-in way?

[web2py] GAE is converting Integers to Longs and len() breaks
My app is working locally fine with a field defined as
Field('Q2V','integer'),
then in the controller I have been able to
len(Q2V)
but after upload to Google App Engine I am tripping with
object of type 'long' has no len()
I've been abel to discover that apparently GAE will map Integers to Longs
for python- um, ok, so how can I measure the length then? Has anyone run
into this and solved it?

Python integers don't have len either. What are you trying to do?

Re: [web2py] GAE is converting Integers to Longs and len() breaks
Shoot, thanks, you're right, that field was a string and I changed it to do
math on elsewhere...
Do you know how to take the far right number of a two digit number? Will
something like field[-1] work like it does on strings?

If you had googled first for "Web2py vs django"
(https://www.google.com/search?channel=fs&q=web2py+vs+django), you might have
noticed the first result:

("Django vs web2py for a beginner developer").

You can always do len(str(thing)), or str(thing)[-1] (though thing % 10 might
be closer to what you want).

[web2py] Re: sharing my d3.js experiments with web2py community
Dave, I put an updated set of d3.js examples on my github page. Try the web2py-1.app.d3anim.w2p which contains more examples, including "overlayed on a page". You can change these examples by adding your own html files by "extending" or "including" html files, and you can read more about this in the web2py manual. Also, this should help you with svg placement, http://alistapart.com/article/using-svg-for-flexible-scalable-and-fun-backgrounds-part-i (and part-2) Margaret On Friday, August 16, 2013 11:07:33 AM UTC-5, dlypka wrote: > > Hi Margaret: > > OK I played with your samples. > Great technology. > I would like to see such effects overlayed onto an existing page. > > - Dave Lypka. > > On Saturday, August 10, 2013 7:47:00 PM UTC-5, greaneym wrote: >> >> >> Hi there, >> >> I am sharing my experiments with D3.js this week.
