[web2py] Cheaper hosting...

[Magnitus]

So far, I've been using this service for my personal apps at 1 node:
http://www.vps.net/product/cloud-servers/

Recently, someone suggested this: http://fibervolt.com/vps.php

At the lower specs range (and assuming you don't use even a 1/10 of
the bandwidth vps provides), you have something that is almost as good
for like 25$/year (instead of 20$/month) and something that is
definitely better at less than 1/3 of the price (6$/month instead of
20$/month).

Seems too good to be true.

Anybody has any experience with them?

[web2py] grid - hiding reconds found count

[peter]

I am hoping that the developers of SQLFORM.grid will add an option to
hide the 'nn records found' message. In fact I do not think it should
appear at all when there is no search in place. I have discovered a
neat way of hiding this message
Put in your layout.html (or more locally if you wish)

.web2py_counter { display:none}


Put it just before {{include}}
Unfortunately it leaves a gap, but it is much better way of getting
rid of the message than editing gluon.

Re: [web2py] Cheaper hosting...

[Marin Pranjić]

If you need very cheap hosting, you can look here: http://www.lowendbox.com/

However, price does matter :) Uptime, customer support...
These providers are good for testing, backup, or small unimportant sites.
It's risky but if you pay monthly, not a big loss if something goes bad.
If you need solid provider, you'll have to pay for it.

[web2py] Re: Question to Bruno on grid and styles

[peter]

I am seeing the comments like a programmer sees comments, you comment
out a bit of code when you want to temporarily disable it. I see that
this is a different kind of comment to a comment where you want the
generated html to contain comments.  Having seen Massimo's video on
floss I can see why the html comments do not affect the python
execution. However for a programmer, having things within comments
execute is an 'unexpected behaviour'. Any way when one knows it works
in this way it is easy to work round.

[web2py] Re: Massimo Di Pierro talks about web2py on FLOSS Weekly

[peter]

I will think about making it open source in the future. The problem is
a) It is my first python and web2py project, so the coding is not
always as clean as an experienced python programmer would produce.
Secondly a music download store is not close to a generic ecommerce
store. When I have some more time I can maybe tidy up the code and
make it an open source music download project. This week I wrote a
picture gallery for my sister in law. I had previously written it in
net objects fusion with the idea that she would be able to modify it.
It proved much to complex so I have to add each picture for her. By
rewriting in with web2py, which took perhaps half a day, she can now
manage it herself. In the near future I will add this as an appliance.
The one there is very incomplete and more javascript than web2py.

[web2py] web2py App for sharing research results.

[Richard]

Does anybody have an web2py app for sharing research data?

We are with a number of teams of students researching the same
subject. To increase the statistical power we want to share research
data so one can increase validity.

A short functional design:
. Users will be authenticated
. This site will be hosted on the Internet, accessible for all
researchers.
. User will have only access to their own and to the created total
dataset.
. This total dataset will contain all shared attributes between the
different research.
. Research data can be viewed in a table.
. Research data is read from excel
. Export to excel of total data set.

[web2py] How about auth.define_tables(..., format='...')?

[Ray (a.k.a. Iceberg)]

Hi Massimo,

How about add a new parameter to auth.define_tables()? As below.

  def define_tables(..., format=''%(first_name)s %(last_name)s (%
(id)s)"):
 ...
db.define_table(..., format=format)
...

The idea is to let user has a change to customize it. Currently we can
override this value at all.

Hi Hassan,

You use so many webfaction slang in your post. Fortunately I use
webfaction too so I can understand.

Yes I think you can install the entire web2py package as a "webfaction
app" for your each "webfaction website". But that way each "webfaction
app" contains at least one dedicate process. Your webfaction account
may exceed memory quota quickly.

I install only one web2py package as a one-for-all "webfaction app".
Then bind my several domains to this unique "webfaction app" via
webfaction control panel, so requests to all my domain go to that same
web2py process. Later, setup some url rewrite rules so requests for
different domain go to different "web2py app". This solution is good
for many light traffic sites.

Hope I describe it clearly.

Regards,
Ray

I think you'd need different format arguments for auth_user and auth_group,

[web2py] slideshow in plugin wiki

[peter]

The slideshow plugin in plugin wiki has a height and width parameter.
Unless I am mistaken, these are not connected to anything and have no
effect.

Eventually I discovered the way to adjust the size of the slideshow
is:

In base.css put

#slideshow1 {
height:  500px;
width:   580px;
padding: 0;
margin:  0;
}

img#slideshow1 {
padding: 15px;
border:  1px solid #ccc;
background-color: #eee;
width:  580px;
height: 500px;
text-align: right;
top:  0;
left: 0
}


It would be good if this were put in the comments of the slideshow
function in plugin wiki. Maybe the section on this in the book could
reflect this.

You have persistent connections: just use the pool: it is documented in the
book.
If you find problems with speed use the profiler that comes with web2py and
post here or open a ticket with the results and a model to reproduce those
problems, they will be fixed.

[web2py] Re: Persistent variables in web2py

[Massimo Di Pierro]

this is not a web2py issue. This is an issue for all web applications.

What if your application is replicated on two server behing a load
balancer? The two servers cannot share objects. What if you use a web
servers that forks (apache can) than different requests are executed
by different processes, not different threads? Processes cannot share
objects. What if you have to restart the web server for maintenance
purposes? Do you want to store all persistent data?
The same user may request two pages and these two pages may be server
by different servers or different processes.

Web applications must be written without persistent objects. State is
share using the database, using sessions and using cache.

The bahvior you seek can be mimicked by serializing/deserializing the
objects at every request in session or cache.

Yes, but as a programmer, you have to use the correct comment syntax for 
the language you are using. In the web2py template language, everything 
outside {{ }} is left as is in the generated output. You can comment out 
code within {{ }}, but you obviously have to use Python comments for that.

Keep in mind that web2py templates can generate any type of output (JSON, 
XML, Javascript, CSS, or any arbitrary language/markup), not just HTML. It 
would not be expected or desirable for it to parse the comment syntax for 
all possible target languages and completely remove the content within. 
Rather, you want the template language to be able to generate comments in 
the target language if needed. This is particularly important in HTML 
because in HTML, sometimes you do actually want the browser to execute 
content within comments (e.g., HTML comments are used to create conditional 
markup for IE and to hide Javascript code within script tags from 
non-Javascript browsers).

Though if you tried to generate an HTML comment using the template language 
but found the content of that comment to be empty within the generated 
HTML, that would also be unexpected behavior.

Nice comment Anthony. So I would like to mend my previous suggestion

1. the auth.define_tables(...) interface remains state quo
2. the auth.define_tables(...) implementation follows some new

db.define_table(

format = self.settings.table_user_name_format)

Probably just settings.table_user_format (i.e., the format for the user

If ALL your other domains only need ONE SAME "web2py app" named
mastro, you are lucky. You only need to rename "mastro" as "welcome"
or "init". Problem solved.

If, in my cases, different domain needs different web2py app to serve,
I use a naive trick. Here is my "web2py app" welcome/default.py 's
index():
Well, my simple

def index():  # serves as a springboard
if request.env.http_host.endswith('site_alpha.com'):
redirect(URL(a='alpha',c='default',f='index'))
if request.env.http_host.endswith('site_beta.com'):
redirect(URL(a='beta',c='default',f='index'))
...

You get the idea.

It is not perfect. End users see a long url, e.g.
http://www.site_alpha.com/alpha/default/index
Besides, if site alpha 's end user types in 
http://www.site_ALPHA.com/BETA/default/index,
oops, he sees contents in site beta. I can live with that. How about
you?

It is possible to use web2py's builtin url rewriting feature, or
nginx's url rewrite feature, which should be faster by the way. But I
did not go that far yet. People who've been there please give some
light.

[web2py] How to hide uuid field in crud create form

[clarix]

Hello,

I added an uuid field to my tables to allow to merge dababases:

Field('uuid',default=web2py_uuid(),writable = False),

The problem I find is that the uuid field now shows in the crud.create
forms. I tried to set the uuid readable property to
False but in doing so the crud.create form not only shows the uuid
field but it also allows editing the field.

I would appreciate any help on this. Many thanks!

[web2py] Advantage to requires clause in controller vs model?

[Tom Campbell]

In the building a minimalist facebook  clone 
video at around 7:30 I see this in default.py:

def search()
 # make a form where to type a name
 form = SQLFORM.factory(Field('name',requires=IS_NOT_EMPTY())) 

Question about the requires. This no difference between putting the 
requires clause there vs. in the define_table() method in the model, 
correct? If not is either way considered to be a better web2py convention? 
Generally I think I'd like it in the model, and put it in the controller 
only where it does something contrary to expected behavior, but I'm a noob.

[web2py] Re: Persistent variables in web2py

Hi Massimo,

In the first post of this thread, Arturo said,

"Is there a way in web2py to have varibles be persistent. For example
when I instantiate a class I don't want to re-instantiate it every
time a page is loaded."

I guess what he concerns is performance. In other word, "web2py re-
instantiate all class, variables, app logics, etc. ... every time a
page is loaded. Isn't that sounds slow?" Do we have a doc for this
faq? By the way, does binary compiling a web2py app help much in this
aspect?

Ray

[web2py] Re: How to hide uuid field in crud create form

[Anthony]

Are you saying Field('uuid', default=web2py_uuid(), readable=False, 
writable=False) doesn't hide the field (it should)? Can you show more code?

Also, note that default=web2py_uuid() will only set the default value once 
per request, so if your code happens to insert multiple records in the same 
request, they will get the same uuid. If you want the default to be a 
function that gets called once for each insert, then just pass the function 
itself as the default, rather than calling the function:

default=web2py_uuid

or

default=lambda: web2py_uuid()

Only the stuff in models, and you can reduce that by using conditional 
models or by moving some code to modules and calling only when needed.

[web2py] Re: Advantage to requires clause in controller vs model?

[Anthony]

In general, you would define the validators with the model. However, the 
example below uses SQLFORM.factory, which is not based on an existing model 
(i.e., DB table definition). In other words, there is no define_table in a 
model file associated with that particular form creation.

[web2py] Using a decorator to choose which view to use

[~redShadow~]

In many cases, I find out that I can use a single view to render results
from multiple controllers, for example, I use this to render forms::

{{left_sidebar_enabled=right_sidebar_enabled=False}}
{{extend 'layout.html'}}
{{=title}}
{{=form}}

So I stored that view in ``default/form.html``, and I was calling that
this way from the controller::

def my_form():
# ...
response.view = 'default/form.'+request.extension
return dict(title=mytitle, form=myform)

But it doesn't look very clear at first look which controllers use which
custom view, etc. so I decided to write a decorator to do that.

I came up with this::

def use_custom_view(viewname):
"""Decorator to be used to customize the view to be used
to render a given controller.
"""
def _use_newcontroller(func):
def _newcontroller():
response.view = viewname+'.'+request.extension
return func()
return _newcontroller
return _use_newcontroller

It works quite nicely, and so I replaced the above ``my_form()`` with
this::

@use_custom_view('default/form')
def my_form():
# ...
return dict(title=mytitle, form=myform)

Then, I decided to move the ``use_custom_view()`` function into a
module, in order to reuse it in many controllers.
So, I created a module named ``helpers`` and placed the decorator
function there.

Now the problem is: how do I access ``request`` and ``response`` from
the module? There are many ways, as passing the two variables as
arguments to constructor, or copying them into the module scope.

I choose the second one, doing this::

helpers = local_import('helpers')
helpers.request = request
helpers.response = response

But I don't like having to do this each time I import that module..
Any suggestions on how to do better?
And, isn't already there something like this in the core?

[Anthony]

You can use the new thread local 'current' object. In your module file:

from gluon import *
def use_custom_view(viewname):
[snip]
current.response.view = '%s.%s' % (viewname, 
current.request.extension)
[snip]

Also, note that local_import is no longer necessary -- now you can just do:

import helpers

[web2py] issueTracking

[mart]

Hi,

I am shamelessly using Massimo's issueTracking and redoing it to
replace my own "request" app (because obviously, massimo does it
better than i could ;) )

If any body has played with it, i would have a few questions:

1) depending on the type of request, i would like the form to expose
different form fields
2) I wold like to do either of the following:

[web2py] Re: issueTracking

[mart]

sorry... i hit 'return' to quickly ;)

continuing:

2) I would like to do have a layout where fields are grouped by
"category", maybe using something like a . I.e.

* category 1
* bla: blabla
* bla_1 : blabla
* bla_2: blabla

* category 2
* bla_3: blabla
* bla_4 : blabla
* bla_5: blabla

* etc

also, in the 'issue' grid, i am not seeing the dafault "view"
button... does somebody know how to get them to display?

ANy help is appreciated :)

thanks,
Mart :)

Re: [web2py] Re: table.format cannot be set after define_table()?

[Anthony]

Now that I think about it, this has already been fixed in trunk. In trunk, 
you should be able to do:

db.person._format='whatever'

without having to first delete _format. That will work for any table 
attribute starting with an underscore, including the new _singular and 
_plural attributes (which are used as singular and plural table labels).

[web2py] Powertable and DAL count

[Wes Hall]

I am trying to show a grouped count in a powertable. How do I
reference the count's storage object?


def event_list():
class Virtual(object):
@virtualsettings(label='Count')
def email_count(self):
return ??? # What do I need to reference?

report_id = int(request.args[0])

count1 = db.events.email.count()
datasource = db(
(db.events.report_id==report_id) &
(db.events.event_type=='event1')
).select(
db.events.id,
count1,
db.events.email,
db.events.name,
db.users.first_name,
db.users.last_name,
left=db.users.on(
db.events.email==db.users.email),
groupby=db.events.email)

table = plugins.powerTable
table.datasource=datasource
table.headers = 'labels'
table.virtualfields = Virtual()
table.keycolumn = 'events.id'
table.columns = ['virtual.email_count','events.email']

...


This is my first web2py project and second python project, so if it is
a lack of basic understanding, pointing me towards helpful resources
would also be appreciated.

Thank you

Nice! It did the job.

BTW, is there any way to automatically watch module files for changes
using inotify and reload() them automatically upon change, at least
during development? Many times it gets confusing when changes in modules
in the modules dir don't apply while changes in controllers etc. does..

Some times ago I created a similar mechanism for a PyQt4 application;
for what I remember I took some code from a CherryPy "autoreload"
component but http://www.cherrypy.org/wiki/AutoReload is a 404 and
http://docs.cherrypy.org/dev/progguide/autoreloader.html seems to work
using a clock instead of inotify to watch files, plus it relaunches
process instead of reload()ing modules..

This will reload modules, but only when they change.

BTW, all of this will be documented in the upcoming revision of the book.

Re: [web2py] Re: WebFactions Applications

[Vasile Ermicioi]

a few steps that I use, I assume that you already installed web2py :)
0) set your domain at your registrar to point to webfaction dns servers
1) add your domain to webfaction domains
2) set your domain to be handled by your app (see webfaction's websites)
3 )create a routes.py (or rename routes_example.py) file with the content

routes_in = (
('(.*):https?://(www\.)?yoursitename1\.com:(.*)/', '/yourapp1/'),
('(.*):https?://(www\.)?yoursitename2\.com:(.*)/', '/yourapp2/'),
 )


def __routes_doctest():
pass

if __name__ == '__main__':
import doctest
from gluon.rewrite import *
load(routes=__file__)
doctest.testmod()

4) restart your server (apache, nginx or whatever server you use)

this kind of installation doesn't need multiple web2py's installations

[web2py] putting a condition in a form

Hi,

does anyone know if I can have some sort of condition in a form (but
BEFORE the form is submitted)?

For example, lets say I have 5 fields in a form where depending on
what a user decides, we would expose 2 extra fields (or not). Anyway
to do something like this? I am open to any suggestion :)

thanks,

[web2py] Re: How to hide uuid field in crud create form

[clarix]

Hello Anthony,

I think I found the problem. I had generated the table with the wizard
and I had an id field in the table. I removed the id field and the
uuid didn't show in the form anymore. I assume you either have an id
field or a uuid field not both. Sorry for my clumsiness, I am a
starter.

Also, thanks for the advice about making sure the web2py_uuid is
called for each individual request.

Thanks very much for your help, it is awesome to get sound answers so
quickly in this forum.

[web2py] Communicating With C Application

[Ialejandro]

Hi! I'm building a simple (really) bank simulator for my class, I need
to communicate my existing web2py app (just a CRUD) with a C
application, what´s the best way to do that??

I mean, I need to have the same CRUD functionality in both sides, web
(with web2py) and client (Ansi C, Unix/Linux/Mac), I'm using the
default SQLITE integrated with web2py.

[web2py] Re: Communicating With C Application

[Ialejandro]

I think the question is fuzzy...

I know It can be done by writing SQL queries from C... but I want to
use web2py as intermediary, so for example,

to insert a new client the C app just send a query like this:

127.0.0.1:8080/bank/remoteCalls/insertClient?name=

but what's the best way to retrieve rows from web2py?

[web2py] Wordpress and web2py

[Kenneth Lundström]

Hi listmembers,

a client of mine asked if Wordpress and web2py could be combined somehow.

He has an Wordpress website and wants to continue using but has some 
specifiec needs that he would like to be solved with web2py.


So when a user logins he does it in Wordpress, then he wants to look at 
some charts that are generated with pychart so somehow we need to login 
the user into web2py without having the user do it.


Any ideas how to do this?

hum... doesn't seem to be working for me... maybe because I am using

[web2py] Re: Persistent variables in web2py

[Massimo Di Pierro]

As Anthony suggests you can move code to modules and import modules.
Module can have global level variables (that do not depend on the user
or the request) that will be persistant within the process that
imports the module.

Database connections anyway, are handled by web2py in an efficient way
already, by using connection pooling.

I know that Massimo was going to work on that once finished the new
documentation, and I am doing some experiments too (although I have to
reverse-engineer the whole DAL mechanism due to documentation lack, and
it's definitely not the primary thing I'm working on..).

Plus (IMHO: don't take this as official since it's only how I see it), I
think it would take some development on the DAL too in order to make
full use of the mongodb features while allowing to keep the same
functionality on other databases too.. (In mongodb you don't care about
the record schema at all, while in other databases you cannot, so either
you don't make use of that or you need something to make a similar
behavior work on all databases too..).

So, I guess the best thing for the moment is using directly pymongo
(using the ``DAL()`` just for the pooling mechanism) and subclass
``Auth`` and ``Crud`` to make them work with pymongo directly.

My personal suggestion is for http://www.hetzner.de/
I have been using their products (both dedicated servers and vservers)
for about five years, and the service is great while prices are usually
lower than competitors.
Their lowest-price vserver is 7.90 EUR/month with 512MB ram and 20GB
HDD; the only disadvantage is that unless vps/linode/.. VMs are on
directly physical machines and not on a redundancy cloud, so it's a bit
less fault-tolerant; anyways, I never get any noticeable downtime, even
when they were turning off routers/switches for maintenance, etc..

Not offhand, no. But there's JSON-RPC documentation on the web that explains 
the protocol pretty well. And there's a client in the web2py contrib directory.

Thanks for the hint. I managed to come up with a seemingly simpler
routes.py for same purpose.

routers = dict(
   BASE = dict(
domains = {
"my_domain.com" : "app1",
"another_domain.com" : "app2",
},
),
)

However, the only downside is only one said app is exposed to the said
domain. What if my domain need two apps to serve?

Ray
