[web2py] Re: How can I set alternative DAL when main DAL endpoint is not available?
The solution is an elegant one, however, there is an issue I want to discuss further after applying it. When the solution is applied, it works but with some trouble that might compromise testability. Since it will try to connect the production db and throws 'OperationalError' after trying to connect it for awhile and then it moves on to the next one, which is the local db for this case. Then, the test takes a lot longer with local db. Can this issue be circumvented so that test "experience" can be as much as like to the technique that I started with this thread (manually toggling on and off db endpoints)? If the issue persists, I guess our team will perform the test a lot more less, or go back to switching the endpoints manually, which is not a too much hassle. But what I am afraid of is that someone forgets to turn the endpoint back to the production before submitting the code and it goes live.

Sorry, that was a typo.
Even something as simple as response.js = 'alert("Here");' or response.js =
'alert("Here");' doesn't seem to work, although it does if

Mmm, site-packages seems to be added in main.py, befor dal is
imported, calling the function create_missing_folders .
If I'm correct, it should see the psycopg2 module
> Is there other way to acomplish these?
I think you could download and install python, psycopg and web2py from
source, and then use py2exe to make an installer.
BTW, I'm working on pg8000 support, a pure python postgresql
interface, you can see the changes in my clone:
http://code.google.com/r/reingart-web2py/source/detail?r=3837efb84b1f
you can download with mercurial:
hg clone https://reing...@code.google.com/r/reingart-web2py/
hg update pg8000
If you try it, please tell me if you find any issue.
With this changes, you'll not need anything else (nor even psycopg2,
and pg8000 is inside contrib)

Psycopg2 has a LGLP licence, the same as web2py, and the license of
libq IIRC is the same as PostgreSQL: BSD so it shouldn't be an issue:
http://initd.org/psycopg/license/
pg8000 has also a BSD-like license

[web2py] Re: Web2py binary distribution and psycopg2 driver
Thanks for your comments.
Do you remember how you did it? I can make it work correctly when
using the source version of web2py, and I install psycopg under the
python installation (c:\python27).
However, when trying the binary distribution, I have tried extracting
the files from the psycopg version for python 2.5, and putting them:
a) Inside web2py\site-packages: They work if I start a shell and try
"import psycopg2", "psycopg2.connect(...)", etc. However they are not
detected as an available driver, and trying to connect the DAL to
Postgres fails with "Unable to import driver"
b) I tried putting the files inside the library.zip file created by
py2exe, but it just didn't work even when importing from the
application shell...
I have managed to get it working using portable python + web2py source
distribution, but I think it would be easier to bundle it with web2py
binary.

Thanks for any help. Thiago

[web2py] How to get name of linking field from two table names
I have a function in which I have two table names 'db.A' and 'db.B'. There is a field in db.A that links to the id field of db.B. But I don't know what that linking field is called in db.A. Is there a way to find this out programmatically? (This is the last nut to crack before I can release the second version of my ajaxselect plugin, adding the ability to filter one select based on the value of another.)
[web2py] Re: Auth user custom update
After processing the form, try: auth.user.update(form.vars) auth.user is just a (dictionary-like) Storage object, so you can update it like any dictionary. Note, if form.vars includes some variables that are not part of the auth_user table (and therefore shouldn't be added to auth.user), you can do: auth.user.update(db.auth_user._filter_fields(form.vars)) The _filter_fields method returns a filtered copy of form.vars including only fields in the auth_user table. Another alternative might be to just use the auth.profile() action (it automatically handles updating auth.user). If you want to limit the fields that can be edited via profile(), you can simply set their .writeable attribute to False before calling auth.profile().

The DAL can be into an if statement. In principle you can test outside whether the connection is available. How would you check it efficiently without wait?

Can you show the code you tried? I tried the exact code you posted and
simply added this to the overview() function:
response.js = '''$(function() {$(".replacewloading").click(function()

Re: [web2py] Web2py binary distribution and psycopg2 driver
I remember the postgresql driver usually works with the source

I think a way u get it working is use the source web2py on windows, and use

[web2py] Bug in languages.py
Hello,
I have discovered a bug where I got read errors for language files (ERROR:
Syntax error in /home/... .../languages/en-gb.py). After some debugging I
found out that the cause is that the file is being read while it is half
written by another thread (or process). There is a lock for it, but the
full contents of the file is not written before close (which is after the
unlock). By adding a flush before the unlock in write_dict, I don't get the
error anymore.
I discovered the error by running system tests with Selenium in parallel, I
suppose there is a simpler way to trigger the bug. ;-)
My patched write_dict in languages.py:
def write_dict(filename, contents):
try:
fp = open(filename, 'w')
except IOError:
if not is_gae:
logging.warning('Unable to write to file %s' % filename)
return
portalocker.lock(fp, portalocker.LOCK_EX)
fp.write('# coding: utf8\n{\n')
for key in sorted(contents):
fp.write('%s: %s,\n' % (utf8_repr(key), utf8_repr(contents[key])))
fp.write('}\n')
fp.flush()
portalocker.unlock(fp)
fp.close()

A simpler fix might be to remove the unlock call. (In fact, it seems to me that
it's an error to explicitly unlock a file that's been locked with LOCK_SH.
Isn't it?)
A precaution (though it only papers over the error) would be to flush in
portalocker before unlocking a file.

[web2py] Intercept file download
Hi guys, For a web application, I have to implement a sort of responsive design for images. There are tons of solution online, but they requires to use some sort of javascript and custom html to work (insert special tags or classes in code). I don't like the approch because it make the code unmaintenable. The idea I have in mind is something like this: 1) On page load, a jquery function calls a controller and communicates infos about the device. 2) Controller stores those infos in session 3) I intercept images download and 3a) If there are session infos about device width and is_mobile, I resize the image with PIL to the exact width server side and give the new url to the response. 3b) If there aren't infos (browser doesn't support cookies) and is_mobile, I resize the image to an arbitrary small size (ex: 480 px) and give the new url to the response. 3c) If !is_mobile, I return the normal url How can I intercept file download also the static ones?

[web2py] Re: How can I set alternative DAL when main DAL endpoint is not available?
It would be great if there is a way to check whether request is originated from local (127.0.0.1) and then set DAL's endpoint to local. Would it be possible, and if it is then, is it recommended to do so?
Re: [web2py] Intercept file download
Thanks Bruno, These not solve my problem! To use thumbor, I have to prepare links using a special syntax, that is what I want to avoid. If I wanted to change links I would have done using responsive design tecniques and my own webserver! @Antony: I know sencha and it adopts an approch like the one I proposed, they have a proxy that intercepts requests to images and resize them basing on the knowledge of the device they have by the useragent. The only caveat is that you have to change all of your urls! I think that we have a framework, we have user_agent_parser and we can include responsive images in web2py! If we can intercept GET to images, we can build something totally integrated with web2py! And this is what I'm doing! I'm thinking of a responsive design module for web2py that can be configured (local processor power with PIL, online service like thumbor) and when plugged in, it makes automatically responsive all of your images. So, my question is, there is a way to intercept GET to static image files? 2012/1/11 Bruno Rocha > > > On Wed, Jan 11, 2012 at 2:23 PM, Bruno Rocha wrote: > >> https://github.com/globocom/thumbor > > > and > > https://github.com/globocom/mugshot > -- Profile: http://it.linkedin.com/in/compagnucciangelo

[web2py] Re: How can I set alternative DAL when main DAL endpoint is not available?
Sure, request.is_local indicates if the request is local (though I think will give a false positive if the site is running behind a proxy server).

Re: [web2py] Intercept file download
Thanks Anthony, Ok, this way I have to play anyway with urls. I'll try another approach. There is a way to rewrite the page after rendering, just before the page will be sent to the browser? This way we can analyze img urls, resize images accordingly, and rewrite the new ones.

[web2py] Re: LOAD, javascript and a loading gif
Two errors. I forgot to remove the tag -- it isn't needed in
response.js because the returned JS is eval'ed. Also, in your code, you
have request.js, but it should be response.js, so try:
response.js = '''$(function() {$(".replacewloading").click(function()
{$(this).parent().html('Refreshing...')} );}
);'''
