[web2py] Re: How do I incorporate git into my web2py workflow?
I use Mercurial but should be basically the same. First, hg clone web2py somewhere on your hardrive. Then in /applications, create a new app (I usually copy welcome). Then cd into the new app directory and git init. Now your app will be version controlled. I host some of my projects on Bitbucket (similar to Github but private projects are free). In that case, I might create the project on Bitbucket and then hg clone it to my hard drive. I don't use any of the git/hg features built in to Web2py.

[web2py] bug in 2.0.8
Hi there,
First off thanks for all of the fantastic work putting 2.0 together.
Looking forward to trying the new features.
I've just upgraded from 1.99.7 - 2.0.8 and I've discovered a serious bug
which has resulted in the loss of my data.
[I'm using both GAE with CloudSQL and dal(migrate_enabled = True)]
The automatically created image_blob references for GAE fields like:
Field('image', 'upload', required = True, length = 100)
Have vanished and with them the data contained in the image_blob fields.
It seems to have happened fairly randomly i.e. some tables are fine but
others are affected. Out of about 6 tables using uploads only two still
have the extra blob columns.
I've had some of these table definitions around for a long time and they
haven't changed. Whereas some others have been edited more recently.
Any help or suggestions would be appreciated. Happy to give mere
information if possible.
Thanks in advance,
Matt
BTW: Also had this problem occur prior to the above:
self.db.executesql(CREATE TABLE IF NOT EXISTS web2py_filesystem (path
VARCHAR(512), content LONGTEXT, PRIMARY KEY(path) ) ENGINE=InnoDB;)
File /Projects/www/gluon/dal.py, line 7234, in executesql

[web2py] Re: Web2py. for a minimalist app, it feels bloated. Do it I need it?
It sounds like you know enough about these things to figure out if Web2py is too bloated for you. My sense is that even if you think it might be bloated, the extraneous stuff really doesn't get in the way too much. Not using DAL means you are missing out on one of the core features. Building a REST API should be fine either using what Web2py gives you out of the bos or rolling your own. You can either build multiple Web2py apps or build some web2py apps and some other apps. DAL doesn't really support NoSQL much at this point so you're on your own there. I've used Web2py to build a POS system and it works great.

Re: [web2py] Re: internal error crash with newest 2.0.6 and old 1.99.2
ok, maybe some progress. i removed any instances of psycopg2 from my computer and web2py by default was and is not forced to use only the contrib/pg8000 driver. i think i would rather use that one anyway. when i changed the pool_size from the default 0 to 16, the initial ticket/exception above stopped being logged. so i was under the impression that all was good again, but then my users have still been having logging in, but this time it tells them it is an unrecoverable error and when i try to see the ticket on their computer after this message, i can't pull anything up. so now i can not trace the problem and the users still have infrequent times the site is crashing unrecoverably. when i look into the ticket logs i only get a bunch of these: Traceback (most recent call last): File /opt/web-apps/web2py/gluon/restricted.py, line 209, in restricted exec ccode in environment File /opt/web-apps/web2py/applications/admin/controllers/default.py https://weinstruct.org/admin/default/edit/admin/controllers/default.py, line 1726, in module File /opt/web-apps/web2py/gluon/globals.py, line 185, in lambda self._caller = lambda f: f() File /opt/web-apps/web2py/applications/admin/controllers/default.py https://weinstruct.org/admin/default/edit/admin/controllers/default.py, line 1548, in ticket e.load(request, app, ticket) File /opt/web-apps/web2py/gluon/restricted.py, line 168, in load d = ticket_storage.load(request, app, ticket_id) File /opt/web-apps/web2py/gluon/restricted.py, line 96, in load return cPickle.load(ef) EOFError but i am not sure what this means because it looks internal to web2py. i have upgraded to 2.0.8 a few days ago; so i am up to date. so i am still having trouble finding if it is the postgresql-9.1, the pg8000 driver, web2py, the DAL, my code, my views, i just don't know. pretty frustrating. lucas --
[web2py] BeautifulSoup parsers when in web2py

[web2py] Re: Best Method to implement a like button
How about: in 'likes' make a unique composite index of both fields
(created at DB level). Try to insert a record. If it fails (because of
the index) then delete instead.
On Monday, September 10, 2012 11:58:03 PM UTC+1, Mark Li wrote:
I have 3 datatables as follows:
db.define_table('songs',
Field('songname'),
format='%(songname)s')
db.define_table('likes',
Field('username', 'reference auth_user'),
Field('songname', 'reference songs'))
with the 3rd table being db.auth_user
I would like to implement a like button, where clicking it adds an entry
to the intermediate table 'likes'. For example, if User1 likes Song1, it
would perform the following:
db.likes.insert(username=auth.user.id, songname=1)
Right now I have the like button as the following in the view:
{{=A('like me', callback=URL('add_like'))}}
and the function as:
def add_like():
db.likes.insert(username=auth.user.id, songname=1)
The problem I'm having is that a user should only be allowed to 'like' a
song once; if the user has already liked the song, clicking on 'like' again
should remove that like. Basically a toggle functionality for the 'like'
button.
I'm not sure how to implement the last part, as it seems checking the
entire database for the existence of that record on every 'like' click is
overkill. Is there an eloquent way (minimal database calls) to go about
implementing this toggle functionality for a 'like' button?

Opened the ticket: http://code.google.com/p/web2py/issues/detail?id=980 Now it was closed with status fixed, but: -AFAIK, fileld.writable still has no effect in computed fields. You cannot set a computed field as writable with crud so it shows the widget. You can with SQLFORM (by using the fields argument), however, entering blank inputs don't trigger the compute function server side. -There's no modification of SQLFORM to process empty form fields as computable (in replacement of a previous or new record value)* -SQLFORM doesn't set computed fields as empty on form creation (I think this should be the default behavior)* * Perhaps it would be necessary to add different checks by field type and a standard way of detecting a blank input in each case. Of course, it's possible to show a given widget and do further record processing in the controller without depending on the computed field facility, but with this changes, it would save that extra code and give a more clean and web2py like interface. --
[web2py] Re: web2py DAL one-to-one relation
I am quite familiar with cascade; I just couldn't figure out how it could
assist you.
In my opinion, Field('','reference other_table', unique=True) should
be supported and work. Maybe you added the constraint later and the DB
didn't accept it because you already had duplicated field contents.
In any case, even if unique=True is not working for the moment, then a
work-around would be to make a unique index on the field yourself. You'll
have to handle exceptions when the insert/update fails due to duplicate
keys.

[web2py] Re: web2py DAL one-to-one relation
I think it does have some effect.
I suspect that your existing data may not be unique.
See whether the following helps:
- If using commandline, try with db.commit() after.
- Try with a new table.
- Look in databases/sql.log and see whether the field was created with
UNIQUE.
- Use a DB management tool to inspect your DB.

Re: [web2py] compute fields do not show up in SQLFORM view form
Now I see what you are trying to do. I do not consider this a bug. At this point this is the intended behavior. You want conditional computed fields depending on user input. If a value is provided use it, if one is not provided then compute it. That is not what compute fields were designed for. What you ask can be done but would break backward compatibility because it would require running the compute callback even if there is a value provided for the computed field and let the callback decide whether to override the provided value. For some an empty value is an acceptable value and for some it should trigger a computation. For me a field has a compute attribute the field is NOT editable in forms, it is only readable.

Re: [web2py] compute fields do not show up in SQLFORM view form
I haven't followed this closely, but instead of specifying a compute attribute for the field, could you instead specify the default attribute as a function? In that case, the field will appear on forms -- if the user enters a value it will be used, and otherwise the default value will be computed. Of course, the record is not passed to the default function, so instead the default function would have to directly access request.vars to get the values of the other fields if needed (so this works with form inserts, but not other inserts).

[web2py] Re: bug in 2.0.8
I found the web2py bug that caused this problem. It was an indentation
issue. Took the occasion to rewrite the logic a little better.
Can you please check this works now? You should be able to update to trunk
and your missing fields should re-appear (they will be hidden,
writable=False, readable=False) but web2py should be able to use them as
intended.
Please let me know asap.

The core will a simply be an advanced rest based api. The other half dozen or so apps will all be built of this core. The either apps will likely be built as a cms like system to manage each other. And as different as a POS in store program. So as many cool things as I thing web2py has, do you guys think its the right system? I know w2p can do great APIs easily. But for that simple aspect, I don't need a milti-application admin interface, or a code editor, and I may not even use DAL. (For my project I may actually use something like neo4j/orientdb/titan. Not sure yet. Might use mongodb as instead). So for that simple part, all the other stuff seems a little bloated to me. Stuff that I won't need. Sure as a whole, all the apps will be built into somewhat of a cms (which I would like to build anyways), for that I'm not sure I would need the web2py admin part. As a cms I would probably have my own interface, even for the admins. How or would web2py admin ui fit in. I know you guys are biased towards web2py, but does it sound like it would be a right fit? Or would it be too complex? In comparison, I feel django is too bloated as well since I would be doing a similar thing, except it would be done quite a bit differently. The core of how it works doesn't seem to fit my ideas. If I don't use web2py, the next best things I see as a starting point are pyramid, or bottle/flask or even wheezy looks pretty cool. What do you guys think? The core great api would be the crux of the other apps. This core is what talks to the db. And each if the apps with build on it. The rest part will be made so they can all communicate with each other based on the URL. The either individual apps, were they to be on their own, I can totally see as a web2py app. So I'm curious how this idea as a whole, would fit into web2py. If it can. Since there are a handful of web2py featured I won't even use. I don't need them to be auto imported if I'm not using them (since I can't see what's being imported). So in a way it feels like bloat.

In that case, the field will appear on forms -- if the user enters a value it will be used, and otherwise the default value will be computed. Of course, the record is not passed to the default function, so instead the default function would have to directly access request.vars to get the values of the other fields if needed (so this works with form inserts, but not other inserts).

[web2py] problem adding members to group
Dear all, I'm testing the pos plugin and have it mostly set up, but I'm stuck. I had commented all the auth statements and have now uncommented them, and was adding the group called manager and before I could add members was interrupted. My session ended, and after that I could not use the admin interface to access the database from appadmin. So I'm now trying to add members through the shell, but I'm getting an error: python web2py.py -S app -M -N -R applications/myapp -A Traceback (most recent call last): File web2py.py, line 16, in module import gluon.widget ImportError: No module named gluon.widget I upgraded from version 1.99 to 2.06 and just added the web2py.app. Do I need something else?

[web2py] MENU helper and Server-side DOM work together?
Hi to all
I want to use the html helper MENU to have in the page footer a menu
totally exploded without sliding items.
I changed the css classes and everything looks fine but I don't want the
first level menu items to be clickable
so the first thing I tried was the server-side parsing to remove
unnecessary tags but in a web2py shell I got
mlist = ... well formatted web2py menu list
In [40]: mmenu = MENU(mlist)
In [41]: mitems = mmenu.elements('a')
---
AttributeErrorTraceback (most recent call last)

Is MENU helper supposed to work with sever side DOM parsing? Is web2py
ipython Shell fault?
Can you suggest something better to try to have first level items menu seem
like simple labels?

[web2py] web2py default layout.html

I used the inspector in firefox to check it, when I noticed that text I had was going out of the container div. This was obvious since I gave the container a different color.

Re: [web2py] Re: Web2py. for a minimalist app, it feels bloated. Do it I need it?
Yes i can definately help with testing. Currently there seems to be 2 existing libs for using orientdb. - Compass: https://github.com/emehrkay/Compass which ties directly into orientdb through its rest interface, and will eventually have binary support. - Bulbs with Rexter: http://bulbflow.com/http://bulbflow.com/ / https://github.com/tinkerpop/rexster/wiki/Rexster-Configuration bulbflow uses a system called blueprints, which is eddentially an orm for most graph databases. then there are a few layers that talk to the different db's. most of them use rexter (second link for configuration for orientdb). While the first option, Comnpass, could probably be easier to work into dal, if bulbflow/rexter is used, we can let people use whatever graphdb they want, as long as it supports blueprint. Which I believe most do. The main difference with them, is there is no relations like has many, belongs to, or many to many. They have edges, which are still relationships, but are represented in the form of fields. For an example, a user, and a post, might have an edge of date (published date), and author (who made the post). And bot hthe nodes themselves, and edges can be searched for.

My sense is that even if you think it might be bloated, the extraneous stuff really doesn't get in the way too much. Not using DAL means you are missing out on one of the core features. Building a REST API should be fine either using what Web2py gives you out of the bos or rolling your own. You can either build multiple Web2py apps or build some web2py apps and some other apps. DAL doesn't really support NoSQL much at this point so you're on your own there. I've used Web2py to build a POS system and it works great.

To start the app will be relatively light weight, but if it works out in my grand scheme could be far more complex.but the core will be fairly simple. something an experienced python dev could probably whip up in bottle in a few days. The core will a simply be an advanced rest based api. The other half dozen or so apps will all be built of this core. The either apps will likely be built as a cms like system to manage each other. And as different as a POS in store program. So as many cool things as I thing web2py has, do you guys think its the right system? I know w2p can do great APIs easily. But for that simple aspect, I don't need a milti-application admin interface, or a code editor, and I may not even use DAL. (For my project I may actually use something like neo4j/orientdb/titan. Not sure yet. Might use mongodb as instead). So for that simple part, all the other stuff seems a little bloated to me. Stuff that I won't need. Sure as a whole, all the apps will be built into somewhat of a cms (which I would like to build anyways), for that I'm not sure I would need the web2py admin part. As a cms I would probably have my own interface, even for the admins. How or would web2py admin ui fit in. I know you guys are biased towards web2py, but does it sound like it would be a right fit? Or would it be too complex? In comparison, I feel django is too bloated as well since I would be doing a similar thing, except it would be done quite a bit differently. The core of how it works doesn't seem to fit my ideas. If I don't use web2py, the next best things I see as a starting point are pyramid, or bottle/flask or even wheezy looks pretty cool. What do you guys think? The core great api would be the crux of the other apps. This core is what talks to the db. And each if the apps with build on it. The rest part will be made so they can all communicate with each other based on the URL. The either individual apps, were they to be on their own, I can totally see as a web2py app. So I'm curious how this idea as a whole, would fit into web2py. If it can. Since there are a handful of web2py featured I won't even use. I don't need them to be auto imported if I'm not using them (since I can't see what's being imported). So in a way it feels like bloat. A reason I don't like django. What do you guys think? Any input is greatly appreciated. --

Looks like MENU doesn't generate a DOM structure until its .serialize()

I'm not sure why it was done this way as opposed to generating the DOM upon

In my opinion, Field('','reference other_table', unique=True)

In any case, even if unique=True is not working for the moment, then a
work-around would be to make a unique index on the field yourself. You'll
have to handle exceptions when the insert/update fails due to duplicate

Re: [web2py] Re: Is 'second option' for one-many available for many-many?
That look right... There ways to write request in web2py when it comes to join.

[web2py] Display Image in text
Hi I like to have an Image Displayed within the Content of an Article. The
Content ist stored in a db table.
Up till now I simply displayed the content by this line {{Article.Content}}
I thought an image with text flowing around the image would freshen up the
article.
I tried the following I put somewhere in the content of my article
Image and replace that Tag with the image.
{{import string}}
{{try:}}
{{content=string.replace(Article.Content, lt;lt;Imagegt;gt;,
IMG(_src=URL(r=request, c='default',
f='download',args=Article.InTextImage.thumb),_style='display:block;'))}}
{{except:}}
{{content=string.replace(Article.Content, lt;lt;Imagegt;gt;, )}}
{{pass}}
{{=content}}
I put the whole part into a try clause so no errors are raised when There
is no Image stored for an Article.
What happens is that every time the except part is executed only removing
my tag.
Is it even possible to do put the Image in a Text that way?

I assume the db itself (MySQL) isn't even in play with this problem.

No good reason. The logic can be moved in the constructor but need to be

Looks like MENU doesn't generate a DOM structure until its .serialize()

[web2py] Re: What data should be private (for security) in a standard web2py installation?
- the dal URI if it contains logins/password/db that is not localhost - eventually janrain key is to be kept private as well. PS: Auth.settings_hmac_key in modern scaffolding apps is not written plainly: it is replaced by Auth.get_or_create_key() that reads from private/auth.key or it creates a new one (so if you don't ship private/auth.key you're fine) My normal environment is having a 0_production.py and a 0_test.py with DAL URI, db connection, Auth and mail parameters. In the db.py reside all define_table() statements. Publishing 0_test.py to the repo, added 0_production.py instead to the ignore list. When deploying to production server, 0_production.py is already there (or transferred separately), 0_test.py is renamed to 0_test.py.bak. Little trick, you can have a 0_Atest.py and a 0_Zproduction.py . As long as all the things defined into 0_Atest.py are redefined into 0_Zproduction.py you are fine (models are executed alphabetically). Anyway it's not recommended, also for performance issues (ideally you have already a deployment script and renaming one file shouldn't be so hard ^_^) On Tuesday, September 11, 2012 9:20:34 PM UTC+2, monotasker wrote: I'm using github for open-source development of some web2py apps and want to make sure I'm not exposing any data that would be a security risk.

In my opinion, Field('','reference other_table', unique=True)
should be supported and work. Maybe you added the constraint later and the
DB didn't accept it because you already had duplicated field contents.
In any case, even if unique=True is not working for the moment, then a
work-around would be to make a unique index on the field yourself. You'll
have to handle exceptions when the insert/update fails due to duplicate
keys.

I am trying to cook up a widget ... ( or a plugin ) inspired from the

it uses radio buttons instead of a dropdown select menu, it is about
selecting a profile picture among a number of pics shown and defined and
where the user has the alternative option to ADD ( or upload his own pic (
by uploading that picture from his computer hard drive for example ) and
have it shown in the same view without refreshing the page with its related
radio button selected to choose the newly uploaded picture from the pack

How can I succeed in tweaking the SELECT_OR_ADD_OPTION widget and mixing
it with the js scripts proposed here :

Please advise, any assistance with this matter will be greatly

It depends. Does content contain HTML?

You should not do it that way because the value of content would be

[web2py] When/how is 'format' used?
I have the following parent-child:
db.define_table('Institution',
Field('Institution_name', 'string', length=60,
required=True,
unique=True),
format='%(Institution_name)s')
db.define_table('Team',
Field('Institution', db.Institution),
...
I retrieve some records:
meetTeams = db(db.Team.id == request.args(1)).select(
db.Team.Institution, db.Team.Sex,
db.Institution.Institution_name,
join = [db.Team.on(db.Team.id ==
db.Participant_team.Team),
db.Institution.on(db.Team.Institution ==
db.Institution.id)])
I pull out some data:
for team in meetTeams:
message += %s %d %s\n % (team.Team.Sex,
team.Team.Institution,
team.Institution.Institution_name)
I return locals(), and I have no explicit view. When meetTeams is
displayed, the field team.Team.Institution displays with the
expected/defined 'format'. When 'message' is displayed,
team.Team.Institution shows up as an int.
Three questions:
1. What's the 'magic' going on that tells the display code for meetTeams
to use the 'format' expression (but not to use it when displaying
'message')? Does it realize it's a row, and the row knows how to display
using the format?
2. Are the results of that 'format' expression stored in the row,
available to me to use? As you can see I can explicitly join with the
Institution to get the name. But if there's an easier way, then I'll do it.
3. If I don't reference Team.Institution in the SELECT field list, will
that avoid the various other SELECTs that get done to 'translate' an
Institution.id to the corresponding name (according to 'format') when
meetTeams is displayed?
Thanks.
