[web2py] Matplotlib not loading on 2.12.3 while loading on 2.11.2

[anonymous anonymous]

I posted this question online and it seems that it would be useful to post 
it here.

tl;dr: I found a work around by creating a symbolic link to matplotlib in 
the modules folder.

http://stackoverflow.com/questions/32428845/why-does-matplotlib-not-work-on-a-digitalocean-vps-with-web2py

I've got a digitalocean droplet and I deployed web2py using this script 
.
 
I installed matplotlib as follows:


ssh root@ipdroplet
apt-get install python-matplotlib


and I can indeed import matplotlib if I simply run python on the command 
line after I've ssh'd. The problem is that when I run my app I get the 
following error:


 Cannot import module 
applications.app.modules.matplotlib

I'm guessing this has something to do with user www-data vs root but no 
idea how to resolve it. Any help much appreciated. The tips that are 
mentioned in this 
 
link unfortunately didn't help me.

Thanks

*EDIT*

I should also mention that I'm not using the binary version of web2py. I've 
also managed to run python as www-data by doing sudo -u www-data python and 
I can import matplotlib there just fine.

*EDIT2*

When I was running locally on web2py 2.11.2-stable it worked fine. On my 
server though I was under 2.12.3-stable. I'm guessing this is probably the 
reason.

[web2py] Preference between programmaticaly building a page vs in .html view?

[anonymous anonymous]

Dear all,

this is my first post as well as my first attempt with web2py. I've read 
through most of the book and have the following question.

Here are a few guidelines I've understood:


   - Each controller/function should have it's own view
   - There are two ways to build up a webpage one is programmatically and 
   one is by modifying the view.

For example I could have a view:


# controller.py


def fun1():

return { 'content' : H1('Hello') + P('this is my first app World') }


def fun2():

return { 'content' : H1('Hello Again') + P('this is the second page') }


and 


views/controller/fun1.html


{{extend layout.html}}

{{=content}}


views/controller/fun2.html


{{extend layout.html}}

{{=content}}


The alternative would be:


# controller.py


def fun1():

return { }


def fun2():

return { }


and views:


views/controller/fun1.html


{{extend layout.html}}

h1'Hello'/h1

p'this is my first app World'/p


views/controller/fun2.html


{{extend layout.html}}

h1'Hello Again'/h1

p'this is the second page'/p


What is the difference, which is better practice? In this simple case which 
pattern is it advisable I follow?


Thank you
