[web2py] Re: Web2Py without Bootstrap
Thanks Massimo! I was searching, trying and finaly get the point. My problem was that I was working exactly in SQLFORM and navbar, that´s why I was seeing things so tied to Bootstrap. I made my own navbar, instead of using response.menu.. for now is pretty fine. Later will discover how to build a helper to create a menu using div a or ul li. Now I´m struggling to customize the smartgrid. =) Thanks again for your help!

The navbar can be customized to not use bootstrap classes but the HTML of navbar is also very specific of bootstrap. If you do not want bootstrap, you should make your own navbar bit expliticely building links to login/logout/register/etc. FORM does not acually use format by default. You can style with SQLFORM(formstyle=...) Some of the options are: SQLFORM.formstyles = Storage(dict( table3cols=formstyle_table3cols, table2cols=formstyle_table2cols, divs=formstyle_divs, ul=formstyle_ul, bootstrap=formstyle_bootstrap, bootstrap3=formstyle_bootstrap3, inline=formstyle_inline, )) You can also make your own formstyles. Look into sqlhtml.py The GRID can also be passed a formstyle and will use it for FORMs. Other css classes can be customized using other arguments.

Is there a way to get rid of Twitter Bootstrap and generate a clean HTML code? Is so annoying this tied structure.

Re: [web2py] Re: Python Performance Issue
People have found lots of variability in performance with apache+mod_wsgi. Performance is very sensitive to memeory/etc. This is because Apache is not async (like nginx) and it either uses threads or processes. Both have issues with Python. Threads slow you down because of the GIL. Parallel processes may consume lots of memory which may also cause performance issues. Things get worse and worse if processes hand (think of clients sending requests but not loading because of slow connections). Apache is fine for static files. gunicorn and nginx are known to have much better performance with Pyhton web apps.

A 2x-10x performance hit is very serious. I was considering dropping Apache and going with nginx/gunicorn in my Linux server, but I'm not sure that's a good idea. Apache is a nearly universal web server and one cannot simply ignore it. Also, I'm not sure I can duplicate the functionality in my current Apache setup in nginx/gunicorn. On Monday, 17 March 2014 21:15:12 UTC-4, Tim Richardson wrote: (I am the furthest thing from being an Apache expert as you can find.) Well, whereever that puts you, I'll be in shouting distance. I guess this means you are using defaults. The defaults are sensible for small loads, so I don't think you would get better performance from tweaking. These default settings should set you up with 15 threads running under one process which for a small load should be optimal that is, it's as good as it's going to get. You get these sensible defaults if you used the deployment script mentioned in the web2py book (the settings are in the /etc/apache2/sites-available/default file) threads are faster than processes, but gunicorn and nginx don't even use threads. They manage their workloads inside a single thread which makes them fast as long as nothing CPU intensive is happening. \ Thanks.

Re: [web2py] pysimplesoap help
Hi piero:
The first choice to connect to a webservice that requires username
password (add_credentials), you will httplib2 installed:
https://code.google.com/p/httplib2
Then you could do:
client = SoapClient(location = location_wsdl,sessions=True,username='admin',
password='xx')
Also, assuming your webservice supports basic auth, you could pass the
Authentication http header directly (it shouldn't need to install external
library):
import base64
auth = base64.b64encode('%s:%s' % (username, password)).replace('\n', '')
client = SoapClient(location = location_wsdl, sessions=True, http_headers={'
Authorization': Basic %s % auth})
Let me know if this solves your issue,

Yes, actually I was thinking setting session=True for every user, but using cache_model=cache.ram just when the user isn't logged in. After your tips and a few tests, now I understand better. Now my goal is this: I want to cache server-side the rendered view **excluding the extended layout**, that is, I have a layout.html and index.html extends the layout. The layout has things that I don't want to be cached (for example, user's navbar). I think in this case @cache.action is not going to work (because it will cache the complete rendered view). However, I managed to achieve what I want, doing this: - A layout.html containing user's navbar and site's header and footer. - An index.html that extends layout.html - An content.html that **doesn't** extends layout.html - An index() controller function that **doesn't** use @cache.action decorator. Instead, the function uses response.render() specifying content.html as the view file to be rendered, and stores the results of the rendering in the cache. That result is passed as a variable to index.html view. In this way, I'm getting the behaviour I want, which is: caching just a portion of the site's homepage. If you see that something is wrong with this approach, please let me know. Until now tests have been ok. Thanks for your help!

The main issue is to make sure the key is unique to the specific content being cached (e.g., if there is a query string in the URL that affects the returned response, make sure that is part of the key).

[web2py] Change 'working...' message in ajax links
I want to change the default 'working...' message presented in an ajax link
while it is waiting for the callback to return. I couldn't find anything
about this in the web2py manual, but looking in web2py.js it looks like the
message can be overridden by setting the data-disable-with value on the
link, e.g.:
myargs = {'data-disable-with': IMG(_src='coolspinner.gif')}
A('mylink', _href=URL('some', 'view'), **myargs)
(I believe the indirect insertion of the data-disable-with property is
necessary because of the hyphens in the property name.)
But how would I change the default for all of my ajax links? Obviously I
can just change line 474 of web2py.js, but that's a bit fragile because
when I update my app with new versions of that file there's the risk of
regression. So is there any way of setting this default value, say in
db.py, for the whole app? If not, is this something we could add to the
api? I suspect it's something that many will want to tweak to fit their own
themes.
On a similar note, is there a way to set a custom default value for the
'content' property of the LOAD helper? (Again, I'd like to set the new
default in one place for the whole app.) I suppose I could subclass the
LOAD helper, but that seems a bit heavy-handed.
Thanks,
Ian

[web2py] Re: Bootstrap3 package - help to test
Although I'm replying late, I just want to say a huge thanks for tackling this. It's something I've wanted to get to for a few months, and it's great to see that I don't have to start from scratch. If there was an initial lack of response I suspect it's just that many people like me happened to miss the thread. Kudos. On Wednesday, January 15, 2014 6:10:25 PM UTC-5, LightDot wrote: Hm.

[web2py] Password feild type seems to save in plain text for me.
I am trying to create a model with an encrypted key so it's harder for
someone to maliciously screw over my customers.
I have the following snippet.
Field('public_gram', 'boolean', default=False),
Field('tag_name', 'list:string'),
Field('deletion_key', 'password')
)
You can see there the deletion_key is a feild type password which I
understand is hashed out so you can't get the original code. However, when
I try to print it I get this...
test
CRYPT()(gram_details.deletion_key)
(gluon.validators.LazyCrypt object at 0x7f56b8305c10, None)
CRYPT()(gram_details.deletion_key) == gram_details.deletion_key
False
Where test is print gram_details.deletion_key
If this is the case then my password is not very cryptic.
Am I doing something wrong?

Re: [web2py] Password feild type seems to save in plain text for me.
How did you insert test into database?
If you use db.tablename.insert(..., deletion_key='test') it will store it
plain text because you are bypassing validators.
You should:
1. use .validate_and_insert(...) instead
or
2. use .insert(deletion_key=db.tablename.deletion_key.validate('test'))
If you use SQLFORM(db.tablename...) it will automatically validate (=hash
the password)

Hi piero:
The first choice to connect to a webservice that requires username
password (add_credentials), you will httplib2 installed:
https://code.google.com/p/httplib2
Then you could do:
client = SoapClient(location = location_wsdl,sessions=True,
username='admin',password='xx')
Also, assuming your webservice supports basic auth, you could pass the
Authentication http header directly (it shouldn't need to install external
library):
import base64
auth = base64.b64encode('%s:%s' % (username, password)).replace('\n', '')
client = SoapClient(location = location_wsdl, sessions=True,

Let me know if this solves your issue,

[web2py] Python Performance Issue, Part 2
I took the shipping code that I ran in Flask (without Apache) and adapted
it to run under Apache as a Flask app. That way, I'm comparing apples to
apples. I'm comparing the performance of the shipping code between Flask
and web2py.
Below, I've included the 'default' file from Apache2/sites-available for
Flask.
Basically, the code in Flask executes 10x faster than the same code in
web2py. So my question is: if Apache is at fault for the web2py app's slow
performance, why doesn't Apache hurt the Flask app's performance? (This
doesn't seem to be related to GIL or WSGI.)

[web2py] Re: What's the correct implementation of cache.action?
@cache.action(public=False) will cache the content server-side and send along in the past cache headers, marking also the content as private, so browsers are forced to reissue the request for that page. On Tuesday, March 18, 2014 5:16:24 PM UTC+1, Anthony wrote: Seems like a reasonable approach. If you don't want to cache within the index function, you could instead use the @cache() decorator (rather than @cache.action). I will give it a try. I haven't tried that because the book suggested using @cache.action, but I will give it a try. Well, you're already using cache() within the index function itself -- it will be no different to use the decorator instead. The main issue is to make sure the key is unique to the specific content being cached (e.g., if there is a query string in the URL that affects the returned response, make sure that is part of the key).

Hi Mariano and thanks for the help.
I did what you said.
I downloaded the httplib2 and the pysimplesoap 1.10
In the pysimplesoad 1.10 the params username and password are not
present anymore
I wrote the following code:
from pysimplesoap.client import SoapClient
location_wsdl = http://docway.demo.3di.it/3diws/services;
wsdl = http://docway.demo.3di.it/3diws/services/eXtraWay?wsdl;
import base64
username='admin'
password='X'
namespace_wsdl = http://docway.demo.3di.it/3diws/services/eXtraWay;
auth = base64.b64encode('%s:%s' % (username, password))
client = SoapClient(location = location_wsdl, wsdl=wsdl,sessions=True,
namespace=namespace_wsdl,http_headers={'Authorization': Basic %s % auth})
But i got the following error:

Hi piero:
The first choice to connect to a webservice that requires username
password (add_credentials), you will httplib2 installed:
https://code.google.com/p/httplib2
Then you could do:
client = SoapClient(location = location_wsdl,sessions=True,
username='admin',password='xx')
Also, assuming your webservice supports basic auth, you could pass the
Authentication http header directly (it shouldn't need to install external
library):
import base64
auth = base64.b64encode('%s:%s' % (username, password)).replace('\n', '')
client = SoapClient(location = location_wsdl, sessions=True,
http_headers={'Authorization': Basic %s % auth})
Let me know if this solves your issue,

Re: [web2py] calling download function page by ajax
content-disposition on ajax requests is not allowed, therefore browser
refuse to show the usual download as file dialog, plain and simple :D
You need to come up with an alternative plan (such as, opening a new window
pointing to the url, open a hidden iframe, using 3rd party libraries that
do the previous, etc)

Re: [web2py] calling download function page by ajax
:(
I already have a workaround where I show buttons for starting download for
each files that are appended on submit, but I hate that from user
experience point of view... I thought about an other solution, where I
could get vars values from javascritp once form is submit trought
session.var but I am not sure it will work.
Do you know such a library?
Thanks

I’ve posted a recipe comment but I don’t see (also) the comment anywhere or any flash message saying it will be checked for approval or so. my 2 cents, Cheers, -- Frank -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] MicroData and Uploaded Images problem
Hello I am implementing some pretty basic micro data information (For Google Searches) and I am having a problem displaying an image uploaded to SQLITE in the Structured Data Testing tool. Here is a screenshot what the information contains http://imagehost.suck-o.com/images/2014/03/19/image.png The logo field is the problem in question. This is the output displayed in the listing http://imagehost.suck-o.com/images/2014/03/19/image2.png I checked the link which is a direct link to download the image in my browser (Normally an image selected in my browser will display in the browser). Is there a way to directly link to the images that are uploaded in to the uploads folder. So that hopefully based on my assumption Google will understand how to handle the image? Thank you for any advice :D -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

Re: [web2py] Python Performance Issue, Part 2
I shall do that. Thanks. With the knowledge about processes=, I've tuned my actual Linux server to eliminate the 10x slowdown. As it turns out, for my 2.4GHz quad-core Xeon with 4GB RAM, processes=2 works best. I found that any other value (3, 4, 5) gave very inconsistent results–sometimes I would get 1x (the ideal) and sometimes I would get 10x. Very bizarre. processes=2 is counter-intuitive. After all, I have 4 cores. Why shouldn't processes=4 be good? Anyway, not only is the shipping code fast, but I find that my overall web2py app feels a lot snappier. Is it just my imagination? If processes=2 is boosting the speed of Python in general, then you would expect all of web2py to benefit. So maybe it's not my imagination. Anyway, the takeaway, I think, is that you must tune the Apache configuration for the particular server hardware that you have. The default processes=1 is not good enough.

Re: [web2py] Python Performance Issue, Part 2
threads=0 is no good–Apache restart upchucks on this. BTW, I haven't experimented with the threads value. Might this also improve performance (with respect to GIL)? Also, I was wondering. Is the processes= solution related to whether you are using the prefork MPM or the worker MPM? I know that Apache is normally compiled to use the prefork MPM.

[web2py] Customisable error messages for a form determined by device type.
I am happily using the web2py FORM and custom validator's for form validation using JSON messaging. The problem I have is a customer wants verbose messages for webpages, but succinct messages for everything else. For eg, On the webpage You must enter an email address, A password is required, is an invalid post code while on an iPhone app or Mobile Webpage, email required, password required, invalid postcode. Device type is easy enough to determine by data from request.user_agent(), so that isn't a big issue. I'm just curious to see how others approach this kind of situation. Obviously, I'd like to keep my registration method and FORM object function common so I don't have to maintain the same code in multiple places. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: MicroData and Uploaded Images problem
You can use attachments=False in your response.download call on your download controller function if you don't want it to download automatically. Although I don't think that's what's causing the google trouble. You can also try adding: response.headers['Content-Type'] = 'image/png' Again, I don't see anything wrong with your original solution. Is it possible the thumbnail generation is the problem or that the logo just isn't supposed to show or something? -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

Re: [web2py] calling download function page by ajax
You might want to look at
http://johnculviner.com/jquery-file-download-plugin-for-ajax-like-feature-rich-file-downloads/
The only fiddly bit is to make sure you set the cookies correctly (see the
documentation for details).
For example:
{{view}}
response.files.append(URL('static','js/jquery.fileDownload/jquery.fileDownload.js'))
{{controller}}
response.js =
'$.fileDownload(http://127.0.0.1:8000/sgddms/label/download_func1?var1=2676var1=2673var1=2678;);'
response.js +=
'$.fileDownload(http://127.0.0.1:8000/sgddms/label/download_func1?var1=2676var1=2673var1=2678;);'

I already have a workaround where I show buttons for starting download for
each files that are appended on submit, but I hate that from user
experience point of view... I thought about an other solution, where I
could get vars values from javascritp once form is submit trought
session.var but I am not sure it will work.
Do you know such a library?
Thanks

content-disposition on ajax requests is not allowed, therefore browser
refuse to show the usual download as file dialog, plain and simple :D
You need to come up with an alternative plan (such as, opening a new
window pointing to the url, open a hidden iframe, using 3rd party libraries
that do the previous, etc)

[web2py] Re: Newby - what is (**dict(form.vars))
hi!
Don't worry it's pretty common question for newcomers :)
This is called Function Argument Packaging and Function Argument
Unpackaging.
arguments could be packaged into list or dictionary:
* - position based arguments
** - name based arguments
def f(*a, **b):
return a, b
x, y = f(3, 'hello', c=4, test='world')
print x
(3, 'hello')
print y
{'c':4, 'test':'world'}
and vice versa, arguments could be extracted for functions
def f(a, b):
return a + b
c = (1, 2)
print f(*c)
3
def f(a, b):
return a + b
c = {'a':1, 'b':2}
print f(**c)
