[web2py] Re: plugin_wiki

[Tim Michelsen]

> What does the roadmap look like for

Yes, that's exactly my question at the moment.

I mean there were a numbert of attempts:
t1, t2, c9, cube2py and now just plugin_wiki.

How much is the core team dedicated to make this more that just a demo
project?

Web development at my company is shaping again as decisions seem to be made.

So before I invest another bunch of hours in yet the next show-off tool?

I tried to convert my self-programmed site into T9 now it tuens out to
be a senseless effort.

So a clear statement is needed.

Because the video is definately HOT STUFF that deserves to be used.
But for production employment I need a statement that ensures future
upgradability just like web2py development ensures backward compatibility.

Thanks and regards,
Timmie

[web2py] OT: email notifications on repo change?

[Tim Michelsen]

Hello,
when we were using bazaar and Lunchpad, there was a possibility to
subscribe to code repositories and Launchpad would send me a email when
a new revision was submitted.

Is there a similar feature with google code?

I could find the setting in my profile.

I welcome your hints.

Would be good if you could use one of the major markup languages as input:
http://en.wikipedia.org/wiki/List_of_lightweight_markup_languages

Currently, your markmin seems to be like Texy (http://texy.info/en/)

A look at converters show how is the life could be:
* http://txt2tags.sourceforge.net/
* http://johnmacfarlane.net/pandoc/

So I may suggest to adapt markmin to one of the major lanuages and then
use a converter.

[web2py] Suggestions for the Basic Authentications

[Tim Michelsen]

Hello,
I recently checked out two sites created by Lasiaf using Basic
authetication and Google authentication; I also just checked out the
default welcome app.

I miss the following features in the authentication system:

option for profile removal

possibility to fully remove the user's profile from the application
currently, we can only change email and password.
But there is no option for the user to remove the profile himself by
using a dedictated button in the profile menu. Adding this would be
great. With increased awareness on privacy this is a must-have for many
"social" sites.

cross-app persistent authentication
---

Imagine you have many applicances (e.g. blog system, wiki, conference
management). These may all be stored as individual apps under
/applications. But I would like to see that a used logged in in the blog
system would also automatically be logged in at the wiki when visiting
the wiki start page.
Is this already implemented?
What are the suggestions to handle this?

Kind regards.

[web2py] suggestions for web2py website

[Tim Michelsen]

Hello,
my suggestion for the web2py webpage

Add a news menu to the top menu and the add the following 3 colums to
the page using RSS aggregation:

left  center
  right
web2py twitter last 5 posts web2py users list english  last 5
commits web2py code

web2py planet last 5 posts web2py users list brazillast 5
commits cube2py code

  last 5 posts web2py users list spanish


This page could then be refreshed periodically be AJAX...

I think, this could help people to stay updated with web2py developments
as easy as possible.

What do you think?

Best regards,

Sorry, there is amisunderstanding:
I would like to provide the user a option to completely remove his entry
(identity) from the application (remove the corresponding entry from the
user table).
This action is like "completly remove my account from the website" ==>
the opposite of "register".

Where do you see the advantage over xlwt?

Maybe Spreadsheet export could be added as core functionality like CSV

I think this is most wanted in business environments.

[web2py] Re: In trunk. admin wizard. Please give it a try (alpha)

[Tim Michelsen]

Hey,
this is very nic.

The only think is that the INFO sentences are
a) not very accessible from the readability pointof view
b)not very helpful. example in step 3:

 You can use special attributes like "integer", "boolean", "float",
"file", "date", "time", "datetime" to specify the fields type. You can
also use "multiple", "notnull" and "unique" to add attributes. To create
a reference just add the name of the table you want to reference.

It does simple to help.

I suggest:
* Divide messages into paragraphs
* have a animated GIF or small video for each step.
* include a WSIWYG editor for the HTML editing

and extended  feature could be the selection of installed plugins and
layout pages for inclusion into the respecitve pages.

Apart from that, this is just sooo biiig thing. Web app development
fully in browser!

Go on!

[web2py:23259] podcast hint: Becoming an Open Source Developer

[Tim Michelsen]

Hi,
in recent times a lot of discussion has been about roadmap, cummunity 
and contribution.

Here is a nice podcast from our "competitors":

Becoming an Open Source Developer: Lessons from the Django Project 
(PyCon 2007)
http://advocacy.python.org/podcasts/pycon/PyCon2007-BecomingOSDeveloper.mp3
It almost seems like a joke: a family-owned newspaper in Lawrence, KS
(population 80,000) releases an open-source web framework. It's not a
joke, of course: today Django is an increasingly popular web
development platform. As an open-source community Django has been
incredibly successful; in Tim O'Reilly's OSCON keynote, he called
Django "the new face of open source."  But it's often unclear how we
got here. How did a couple of programmers at a newspaper convince
management to contribute to the open-source ecosystem? How does the
company justify the time its developers spend on open source? And how
have we as individuals and as a business had to adapt to become better
open source developers?  In this session: ten lessons in becoming an
open source developer from the Django project.

I think a good piece to learn from.

Kind regards,
Timmie

I also believe that this is where to go.
Instead of creating your own spatial stuff, create plugins that extend 
the DAL for spatial data bases:
* postgis based on postgres
* spatiallite based on sqlite
* upcoming google api

Maybe this sets us apart from competing frameworks and attracks more 
geo-hackers.

[web2py:23918] editing static files from user pages?

[Tim Michelsen]

Hello,
is there any app or controller out there that lets me edit text files 
saved in the static direcory?

I am looking for a functionality just like we have in admin.

I want to achieve:
1) user logs in
2) sees a list of files in a pre-defined directory from static
3) user selects the file and edits it
4) changes get written to the file
5) user logs out

I know I could simply replicate parts of the appadmin to the frontend.
But maybe someone has already done such a thing...

wanted to try GAE deployment as shown in

1) not really documented how to do this quickly!
2) I found out that I need to have appcfg.py. Unfortunately, it's 
absolute path is hardcoded into
applications/admin/models/0.py
Why do you not use web2py root directory as default?

Actually, you start to hit the walls of the zero-config paradigm...
I'd like to support the idea of a comon static direcory which could also 
be the default place for tthe appcfg.py
Any other place could easily changed by symlinks...

3) I put it into
/var/devel/web2py/web2py_gae/appcfg.py

This would be very convenient.
For example, sometimes one only wants to test out the same page with 
different results.

I tried this in a controller

In [4]: controller_page1 = "test"

In [5]: controller_page2 = controller_page1

In [6]: contr
controller_page1  controller_page2

In [6]: controller_page2
Out[6]: 'test'

but the page call for controller_page2 would lead to an invalid request.

I like that statement. Keen to see what follows up.
I mean, you add neice little features every week and asure to maintain
backward compatibility.
But I really miss a roadmap with release dates.

mdipierro :

True. And I guess this applies even for memebers of this list.

Such posts as
http://groups.google.com/group/web2py/msg/61d0e1356ac1252a
are interesting.
But will not change a lot until something changes in the project set up.

I agre with Hans here:

For my topic of contribution I would suggest you to install pydocweb on
your server:
http://groups.google.com/group/sphinx-dev/browse_thread/thread/b77ff5ed73faf410
http://code.google.com/p/pydocweb/
http://gminick.wordpress.com/

Although written in Django, it offers the great opportunity to get nice
shiny and valid docstrings with doctest more sooner than later.

a good notice: I was asked by my potential users to continue my app
development today.

Best regards,
Timmie

Here is a matplotlib based version:

# CONTROLLER:

def image_mat():
 import sys
 import matplotlib
 matplotlib.use('Agg')
 from pylab import plot, savefig
 plot([1,2,3])
 response.headers['Content-Type']="image/png"
 savefig(response.body)

 return response.body.getvalue()

# view

   

=> this can be extended for interactive plotting using
* form as input
* numpy /scipy as support for the math

@Massimo
You may add this to the examples.

[web2py:26327] ho to exchange data between controllers

[Tim Michelsen]

Hello web2py folks,
what is the preferred way to exchange parameters or variables between 
views and controllers?

I have a page where a form gathers input and then a plot is generated 
according to these inputs.

I am currently using the following setup:

## in VIEW
Input form
  {{=form}}
Submitted variables
{{=(request.vars.number, request.vars.hold)}}


   
   


# in CONTROLLER
def plot():


 form=FORM(TABLE(TR("Your number:",INPUT(_type="text", 
_name="number",requires=IS_FLOAT_IN_RANGE(0, 10))),
 TR("Overlay new 
curves:",INPUT(_type="checkbox",_name="hold", value=False)),
 TR("",INPUT(_type="submit",_value="SUBMIT"
 if form.accepts(request.vars,session):
 response.flash="form accepted"
 elif form.errors:
 response.flash="form is invalid"
 else:
 response.flash="please fill the form"
 return dict(form=form,vars=form.vars)


def image_mat_form():
 number = float(request.args[0])
 hold = request.args[1]
 if hold == 'on':
 hold_check = True
 else:
 hold_check = False


 import sys
 import matplotlib as mpl
 mpl.use('Agg')

 #from pylab import plot, savefig, legend, hold
 import matplotlib.pyplot as plt
 import numpy as np
 import scipy as sp
 import scipy.stats as st

 plt.hold(hold_check)
 t = np.arange(0.0 , 5.0, 0.05)
 s1 = np.sin(number * np.pi * t )
 s2 = s1 * np.exp(-t)

 plt.plot(t, s1, 'g--o', t, s2, 'r:s' )
 plt.legend(('sine wave ', 'damped exponential'))


 # plot([1, 2 , number])
 response.headers['Content-Type']="image/png"
 plt.savefig(response.body)

 return response.body.getvalue()

is there a better option for exchanging the form data than
args=[request.vars.number, request.vars.hold] -> number = 
float(request.args[0]), hold = request.args[1]?
I will extend this and the "request.vars" will be many more.

Please tell if you do not understand my question.

Also I'd like to know how to add a file upload field to a FORM.

Thanks in advance,
Timmie

[web2py:26361] Re: ho to exchange data between controllers

[Tim Michelsen]

BTW, when doing this scipy/matplotlib stuff I noticed that web2py does 
issue tickets when something is wrong with third party libraries.

E.g. if I write

2* pi
instead of numpy.pi
the image is not drawn (wrong namespace addressing) but also not ticket 
is issued.

It should be np.sin & np.ext. But if I forget to reference the module 
with "np." web2py does not issue an error ticket. It
just doesn't render any image.

I may suggest to grant these selected developers editing rights to the

Then, they could update roadmap & how-to-contribute pages.

I suggest to add a new page to the web2py page:
Development with subpages
* roadmap: put content of messages
- http://permalink.gmane.org/gmane.comp.python.web2py/14110
- http://permalink.gmane.org/gmane.comp.python.web2py/13864
* how to contribute: put the procedure depicted below:

reported,

Then you make an experiment:
Go on your journey and enjoy. See what happens. how the community can hadle.
As the guy at the Pycon presentation said:
He foudn out that some people can only contribute here and there. Small 
pieces.
He got success integrating them by setting up a supporting 
infrastructure and right channels of communication & handling.

Have a good trip!

Good that they work with mercurial which is inteded for web2py, too.

For what it's worth:
I success created a converter for Lyx:
http://www.lyx.org/trac/ticket/6042
Unfortunately, the patch isn't finished due to time constraints. But 
it's fairly easy to export Lyx (WYSIWYM) -> RST.

I tried to show some here:

you can use a simple editor that involves good syntax highlighting. Like

sorry, I don't understand.

Yes, I changed it into a path that points to web2py root.
I put appcfg.py there.
The process starts.

BTW, one can only hit the GAE deployment button if appcfg.py is found. 
If not, it will not appear in appadmin.

@Massimo:
I am ready to test it.

I succeded in using OpenLayers.
Quite easy with web2py.

But the relevant java code in a file called mymap.html

then modify the view:

{{extend 'layout.html'}}
{{extend 'mymap.html'}}

{{try:}}{{=H2(message)}}{{except:}}{{=BEAUTIFY(response._vars)}}{{pass}}

{{=T("click here for the administrative interface")}}
{{=T("click here for online examples")}}
{{=T("click here for the Show 
Doc Test")}}

=> the map is now reusable.

=> you still need to write the java code yourself.
But you can just start with the simple examples at:
http://openlayers.org/dev/examples/

I don't know what interaction with web2py or database you need.
Also search the list archives for "geo".

[web2py:29853] Re: creating and importing from CSV

[Tim Michelsen]

> My questions:
> * Do I need to fill something in the first column: wmostations.id?
> * Why does web2py not parse the file?
> * Is it possible to wrap text with " some text, with comma"?


I found the thread: http://thread.gmane.org/gmane.comp.python.web2py/16808

Here is what helped in this particular case:
1) going to the database admin for the table
2) enter the first line of the data and hit enter
3) the validators for field types give feedback on the validity and help 
to reformat the input file.

CSV import seems to have the following conventions:
1) delimiter must be a comma: ,
2) a text separator like "" is accepted.

=> I recommend to use Openoffice which has more export options for the 
CSV export.

I would still like to ask for the following feature:

* Could the import tool be expanded to add support for more dialiects
  (e.g. other delimiters)?
* Better documentation of the CSV import in the manual or else where.

I see that others do also have these problems.

Best regards,
Timmie

[web2py:29855] Feature proposal: easier table creation

[Tim Michelsen]

Hello,
I would like to ask for a tool that helps to create tables.

This could be implemented as follows:

1) In the admin there could be a spreadsheet app that feeds  a table 
definition tool.
* In such a spreadsheet the user would enter in the rows:
field name, field type, field description, further parameters.
* this could be converted in a draft table definition written to a file 
in models and imported in db.py

2) use DBF tables which contain the the table field definitions and can 
be easily created from spreadsheet applications.
Python libraries can read these and web2py tools could automatically 
create table definitions from this
* http://www.sqlite.org/cvstrac/wiki?p=ConverterTools
* http://pypi.python.org/pypi?%3Aaction=search&term=dbf+sqlite&submit=search

What do you think?

Best regards,
Timmie

I think for large data bases, it would also be good to have a CLI based

[web2py:30337] connecting to existing SQLite database

[Tim Michelsen]

Hello,
I have troubles connecting and using an existing SQLite table from web2py.

Here are my steps and difficulties

1) imported an existing table into sqlite
2) table definition with migrate=False
=> I get no values/entries shown in the database administration!

If I set migrate=True I get an error ticket telling that the table exists.

"OperationalError: table mydata already exists"

Why does this happen?

How can I connect to an existing sqlite table?
Do I need to create a ID column before?
Can I  define another table field as id?

Thank for your help in advance,

Actually, you don't need to create tables.
Because you seem to upload different data everytime for new calculations.
Would that mean that you create a new table in the database everytime?
I doubt that you want this.

Do you care for storing the input in web2py?

If not,
1) just read serve your data as a stream to a StrinIO.
Massimo may tell more about this.

2) read the stream with numpy into an array:
Example: 
http://www.nabble.com/numpy:-loadtxt-with-default-value-td24987747.html

3) then use array for your number crunching.

Yes, if Alvaro would create a Sphinx sandbox on his box we could even 
use web2py to edit the Sphinx doc and the docstrings online.
like the numpy community.

Again, I tried to help some months ago. My priorities have changed and I

I tried to create a API documentation but got stopped by the following

Maybe it works with all the recent bug fixed?

What I have is a CSV file.
The data is from:

I converted this into a SQLITE file with sqlite-browser.

How can I make web2py connect to that data base?
Normall, web2py would require to generate its ID field.
But I would rather use the "Number" column as id / identifier.

Could you please give me some hints?

Thanks in advance,
Timmie

thanks for the response.

How can I use the first number as PK in this better version of the list:

Please assist.

Thanks in advance,

Thanks.

By this appraoch you import the data into the database used by web2py.
What if the data base already exists as a independant sqlite file and I
just want web2py connect to that one?

How would I show web2py (my model) which field to use as ID?

Thanks,
Timmie

Thanks a lot for your verbose help! I really appreciate it.

I am not a database guru. So I still do not understand why t.staid could
not be the PK (= ID).

I did it like this:
* copy web2py_ajax.html to web2py_ajax_ol.html
* in your map view use web2py_ajax_ol.html instead of the default.
* put the java script stuff in the header of that file
* see if that works. the examples of OL can help you.

[web2py:19175] Re: using web2py for Geo / GIS stuff

[Tim Michelsen]

Hello,
thanks for everyone how responded to my inquiry.

I can see that the interest in geo stuff is there.

What would you guys think of the idea to put the stuff from Sahana and 
pycon into a common respository and develop the geo functionality together?

Thanks again and regards,
Timmie

Nice.
What would you suggest?
The web2py repository or an external one?

Why not an example app?

What about entering a request at Launchpad and then post it at the 
mailing list for discussion.
What I can see from the short time I am following this project I get the 
impression that:
* a lot of useful tips get burried in the mailing list
* some mails are left unanswered
* the documentation in the manual is good for learning but getting outdated.

So, to my opinion, it could be useful for tracking purposes to keep docs 
and issues at a central place.

Thanks for your work on this smart app,
Timmie

Hello,
thanks very much for your response!

I was more thinking of something like:

In [1]: import numpy as np

In [2]: a = np.zeros(10)

In [3]: a
Out[3]: array([ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.])

In [4]: resh = a.reshape(2,5)

In [5]: resh
Out[5]:
array([[ 0.,  0.,  0.,  0.,  0.],
[ 0.,  0.,  0.,  0.,  0.]])

In [6]: transp = resh.transpose()

In [7]: transp
Out[7]:
array([[ 0.,  0.],
[ 0.,  0.],
[ 0.,  0.],
[ 0.,  0.],
[ 0.,  0.]])

Promt [5] / resh shows the default output of SQLTABLE. I would like to 
have [7] / transp.

I think the quickest would be if I read the result of the query into an 
string array and then transpose it and convert back to with transp.tolist().

Rebuilding the table with the header, rows format in the view by using a 
hand-made HTML table is not in the elegant style of web2py.

But I will try yours and see what I get.

Regards,
Timmie
