[web2py] Which checker (PyChecker, Lint, PyFlakes, ...?) is good for using with web2py projects, and how?

[nick name]

What works?
What doesn't work?
What are the pitfalls?

Do you need to write any "if 0: import ..." statements to make it recognize 
the functions?

Thanks in advance.

[web2py] Re: [web2py:34669] Re: Does your Response Flash get in the way?

[Annet]

I have been struggling with the flash messages as well. At the moment I 
have a separate view flash.html:

{{if response.flash:}}
  
x
{{=response.flash}}
   
{{pass}}

In this view I use Bootstrap's alerts to style the flash messages. 
'alert-info' is the one I use most, in case I need another alert set it in 
the function:

def index():
...
if form.process().accepted:
...
alert='alert-success'
elif form.errors:
alert='alert-error'
else:
...
   return dict(alert=alert, ...)

In my views I simply include {{include 'flash.html'}}

This works for now, to come up with a more sophisticated way to set the 
alerts is on my to do list.

[web2py] Re: [web2py:34669] Re: Does your Response Flash get in the way?

[pbreit]

It's controlled with CSS in the web2py.css file. Look for "div.flash".

With the new bootstrap support, I put this in my layout.html:

{{if response.flash:}}

  ×
  {{=response.flash}}

{{pass}}

How can I change the location of response.flash. It overlaps with my menu 
items...

Thank you,

[web2py] Re: Is the welcome.w2p file missing in Version 1.99.7?

[Massimo Di Pierro]

Now I see the problem.

For now you should be able to do

echo '' > NEWINSTALL
python web2py.py -a 'hello'
Ctrl+C

when starting with apache the first time it skips the logic to create 
welcome.w2p.

Hi Massimo. Thanks for the reply. I DID do what you said to do. Here are 
the commands i ran. 


[web2py]$ echo '' > NEWINSTALL

epydoc.css   modpythonhandler.py   setup_app.py
fcgihandler.py   NEWINSTALLsetup_exe_2.6.py

I still don't see any *welcome.w2p* in the *web2p*y directory. In addition, 
i think the purpose of the   $ echo '' > NEWINSTALL command was to create 
the NEWINSTALL file. However, i am NOT sure, but i believe,  that file 
already existed as shown by the $ ls of the web2py directory in my original 
post.

Is there something else I need to do?

Thanks in advance.

Love and peace,

Joe

[web2py] grid/smartgrid ondelete issue

[weheh]

I gave grid (and later tried smartgrid) an ondelete parameter, but it's not 
getting used at all by the grid object. Inspection of the grid's Delete 
button shows the onclick action to be the same regardless of whether or not 
I have an ondelete argument to SQLFORM.grid.

Related questions, assuming the ondelete argument worked as expected:
- How to pass the .id of the intended record?
- How to get the signature?

Could it be that part of the problem may be that my query is considered an 
unsupported query because it has a left join?

[web2py] Re: conflicts with issue 778

[Carlos]

Hi Massimo,

In summary, just revert changeset # e808fd6f684a, since that code is 
already included in the assert_status function.

Thanks,

   Carlos

[web2py] Symbolic links in the applications directory...

[Doug Philips]

I can only find one mention of symbolic links in the book, under:
http://web2py.com/books/default/chapter/29/4#Application-init

That seems to imply that symbolic links at the applications directory
level are ok.
Specifically, if I have the following applications:
ProjectX2010
ProjectX2011
ProjectX2012
and then I symbolic link ProjectX to point to one of them, say
ProjectX2012, is the underlying database safe if I have clients using
the ProjectX2012 and ProjectX applications at the same time?

The one mention of symbolic links seems to say so, but that's pretty
'backhanded' way of saying symlinks won't cause any corruption with
simultaneous access, etc.
I'm interested because I have several instances of ProjectX (and
ProjectY) planned, and if symbolic links are safe, for my use case
here, symbolic links seem a lot easier than doing URL
rewriting/routing. If I've missed where this is talked about in the
book, a link or even a better, a better term to search for would be
great!

Thanks,
 --Doug

Re: [web2py] Re: web2py still unable to create application on WebFaction

[Massimo Di Pierro]

The file welcome.w2p does not ship with web2py. It is created when the 
file NEWINSTALL is present. NEWINSTALL ships with web2py. How did you 
upgrade? If you upgrade from trunk, it is not there.

Why do you say that? The exception is raised by the app controller, not by

[web2py] Is the welcome.w2p file missing in Version 1.99.7?

[JoeCodeswell]

This is a continuation of the "web2py still unable to create application on 
WebFaction"
 
topic.

When creating a new simple app from the web admin interface i get "unable 
to create application "newapp" (it may exist already)".  I had this problem 
occur AGAIN, TODAY on WebFaction, when I upgraded to Version 1.99.7 
(2012-03-04 22:12:08) stable, Running on Apache/2.2.17 (Unix) mod_wsgi/3.3 
Python/2.7.3. 

I checked and there is NO *welcome.w2p *in the  *web2py* directory. Here 
are the ssh commands i used to upgrade.  


$ cd PATH/w2py/apache2/bin
$ ./stop

$ cd ../..
$ rm web2py_src.zip

$ wget -q http://www.web2py.com/examples/static/web2py_src.zip

I can see the site in a browser and get to the web-admin interface. I 
cloned the Movuca demo from GitHub and it seems to be working. But when I 
create a new simple app from the web admin interface I still get "unable to 
create application "newapp" (it may exist already)". And subsequent $ 
lscommands show there is STILL NO 
*welcome.w2p *in the  *web2py* directory.

I hope I have been clear enough in my description. Here is my question. 

How can i get a *welcome.w2p *into the *web2py* directory so i can create a 
new simple app from the web admin interface?

Thanks for the help. 

Love and peace,

Joe

No, it's unique to the current request (that's why it's called current).

But web2py itself saves things there, like current.request, and there's no 
guarantee that it might not save something like current.db in the future, which 
you'd be clobbering. So you're better off doing something like

current.app = Storage()
current.myappname.db = db

Nag: I really think that we should be executing that first line in gluon 
itself, and officially reserve current.app for use by the app.

Re: [web2py] Help me get a better feel for efficient code

[Cliff Kachinske]

Thanks, Jonathon,

Does that mean there's only one instance of current for a running instance 
of Web2py?  So if I do current.db, it could overwrite a current.db assigned 
in an earlier request?

[web2py] Re: Fluxflex will be shut down and no longer available on June 30, 2012

[greaneym]

Hello,

people can also consider using RedHat's Openshift services for hosting as 
they do support python.  They will be soon offering commercial pricing but 
maybe for many people their free platform is sufficient.  Please contact 
Sumitha Nathan for details, snat...@redhat.com.  I got her permission to 
send this to the list.

I see that other people on the list have tried this hosting platform.  I 
think RedHat's hosting will be around for more than 2 years:)

It shouldn't really matter. But where is the caller and callee? If the caller 
is in a controller and the callee is in an imported module, for example, I 
don't think it makes much difference. I'd avoid current where you don't really 
need it (and if you do use current, using current.db is a little risky; try to 
give yourself a safe namespace).

Right. I'm working on a back end for an iPad app that uses that general setup. 
The development environment is local to my map, and the text box is a 
small-scale imitation of the production box (both Rackspace servers, as it 
happens), with identical configurations.

Minor changes I just push out to the test box, but anything that's more 
involved goes through all three.

(To my original restart question, though: think of it as an academic project. 
If you wanted to recognize a restart from inside an app, how would you go about 
it?)

[web2py] Help me get a better feel for efficient code

[Cliff Kachinske]

I'm just starting to use modules with classes for code commonality.

I don't have a good feel for the most efficient way to, for example, pass 
the db to a class method.  I can think of three ways.

- Pass it in when you call the method.
- Pass it in when you initialize the class
- Import current, do something like current.db = db and then pass current 
to the class's __init__

Any opinions on this?  All help greatly appreciated.

[web2py] default foreign key

[Vincent]

Hi,

I'm looking for a way to define a default foreign key dynamically.

For example if I have the following schema:

db.define_table('owner',Field('name', 'string'), 
Field('isdefault','boolean',default=False))
db.people.insert('name'='Bill')
db.people.insert('name'='unknown',isdefault=True)
db.define_table('dog', 
Field('name','string'),Field('owner',db.owner,default=))
db.dog.insert(name='Fido',owner=1)
db.dog.insert(name='mutt') # hopefully points to "unknown" in owner table

Is there a way I could dynamically check the "owner" table and return the 
id of the first row where isdefault==True whenever I define a new "dog" 
without an owner?
In the example above the "mutt" row should have owner==2 ("unknown" in the 
owner table).

Trying to put a function as the default argument does not work. I realize I 
could set the owner to always be the first row in the table but I would 
like something more robust and flexible.

Thanks
Vincent

Re: [web2py] Re: recognizing web2py restart

[Cliff Kachinske]

It's not unusual to have a setup like this:

development box -> test box -> production box

The test box is a clone of the production box, as much as you can make it 
so.  No reason why it couldn't be a virtual machine, but it has to be there 
to prevent surprises due to different patch/version levels of the various 
packages in the system.

"links" is a list so you could add more items to it.

links = [lambda row: A(T('action 1'),_href=URL("acontroller

   lambda row: A(T('action 2'),_href=URL("acontroller

[web2py] Re: web2py: crud interface and query strings

[Anthony]

Two problems:

   1. You are using partnum as a GET variable, but it is also the name of 
   one of the form fields, so when you submit the form, there is a "partnum" 
   in both the GET and the POST variables. When the same variable appears in 
   both the GET and POST variables, web2py puts them in a list in request.vars 
   -- so, in this case, upon form submission, request.vars.partnum is 
   ['12345', '12345'] instead of just '12345'. To avoid that problem, you 
   should refer specifically to request.get_vars.partnum instead of 
   request.vars.partnum.
   2. Issue #1 caused your query to return no results, but you don't have 
   any logic to check for no results (which would be a problem even without 
   issue #1), which is why you got an error ticket.

Your code also includes some unnecessary checks and variable assignments. 
Here's a much simpler version of the code:

def update_inventory(): 
if request.get_vars.partnum:
row = db(db.invent.partnum == request.get_vars.partnum).select().
first()
return dict(record=crud.update(db.invent, row.id) if row
else 'Part #%s not found' % request.get_vars.partnum)
else:
return dict(record="No part number. URL should read 
update_inventory?part=12345")

Note, I removed the check for duplicates:

# check to make sure there are no double entries in database
if(len(rows) > 1):
record = "Database Error"
return dict(record=record)  

That shouldn't be necessary, because in your model definition, you have:

Field('partnum', unique=True),

Setting unique=True tells the database not to allow duplicates, so if you 
try to enter a duplicate, you'll get an operational error from the 
database. However, getting an error from the database isn't a friendly user 
experience, so in addition to setting unique=True, you should also add an 
IS_NOT_IN_DB 
validatorto 
the field -- the validator will be enforced at the form level and will 
result in a friendly error message being displayed on the form when a 
duplicate value is submitted:

Field('partnum', unique=True,
requires=IS_NOT_IN_DB(db, 'invent.partnum')),

[web2py] Re: Errors creating/reading tickets

[Frederick Yankowski]

The fix that I saw was just to ignore the exception during unpickling.  As 
selecta said at least that allows viewing the other tickets. It does not 
address the root problem of corrupted error files being created.

[web2py] Re: Newbie Alert: A flow chart of how things happen

[Omar Ali]

Thank you all for your feedback. I suppose that's correct. I should try to 
change my way of thinking about writing applications from plain simple 
event-driven programming. It just felt so natural thinking about it that 
way... 

I will definitely go through the online manuals thoroughly and then if I 
have more questions, will come back here. This is actually my first ever 
forum post. I was always reluctant to post questions thinking I'd never get 
timely responses, but I read somewhere that I should give web2py a shot and 
see how "friendly" the community is.. :) so Good first experience.

Hope to be able to add back to web2py. It looks good so far

 There are several measures we might take to tighten up default security

 1. Use IS_STRONG() by default in the welcome application template.

 doesn't have to be appended to the hash, since it's already available).

 3. Add a meta hash method for migrating hashes. Let a site that's using

 a hash type of MIGRATEHASH(WEAKHASH, STRONGHASH). The rule for this method

 6. Consider some mechanism that requires a user to choose a new
 password (aging, perhaps), so that IS_STRONG can be enforced.

 7. Encrypt the user table (or at least critical fields in it) with a
 secret key, so that if someone gains access to the database, they don't get
 access to email addresses or password hashes. This raises the question of
 how to keep the secret key secret, but at the very least it can be kept
 separate from the database, say in an access-controlled file in the
 filesystem.

 8. Note that (7) introduces the general problem of secret-key
 management, which is also an issue for HMACs. Some general solution would
 be nice.

 9. Finally, none of this helps against a stolen-password attack. For
 that, we ought to be supporting two-factor authentication. I assume that we
 can do this already via third-party methods; perhaps we could identify
 someone supporting something like the Verisign dongle.

For example:

"When users log in, if their passwords are stored with anything other than 
the preferred algorithm, Django will automatically upgrade the algorithm to 
the preferred one. This means that old installs of Django will get

[web2py] Re: backward-compatible CRYPT() upgrades

[pbreit]

Bumping since another password compromise came out today (last.fm).

I would like to at least salt my passwords. Also would be nice to have a 
bcrypt option. Finally, would be nice to have an easy way to migrate an 
existing set of users to new password scheme as they log in (or I've also 
seen suggested encrypting current encrypted strings and then checking both 
ways in the future).

[web2py] Re: uWSGI + Cherokee + web2py - a howto.

[Leopold]

I am not committed to cherokee and if this goes unsolved then I would be 
forced to choose another webserver, Apache seems overkill since my app is 
only used by intranet users; I am taking a look at Nginx at the moment. 
Still, I'm a bit reluctant to just forget about it since it worked 
wonderfully until now and I have a feeling it may be just a minor thing but 
I just cant find what it is.

Anyway thanks for the suggestion but in the meantime if somebody knows how 
to fix this please post, even it is just for future reference...

Re: [web2py] Dynamic model creation

[Andrew]

Check out http://www.web2pyslices.com/slice/show/1491/plugin-lookout

I have a need to open up other databases and inspect their structures, by 
looking at the other system's catalog.  The slice above also does that.

[web2py] Re: uWSGI + Cherokee + web2py - a howto.

[pbreit]

Are you committed to Cherokee? I would advise against that since 
development has stalled/stopped and instead consider Apache or Nginx. If 
Nginx, web2py includes a setup script:
http://code.google.com/p/web2py/source/browse/scripts/setup-web2py-nginx-uwsgi-ubuntu.sh

You can either run the script as-is or, a better idea is to just manually 
run each step so you get an understanding for what's going on and can fix 
any problems.

Re: [web2py] Re: A Web2py CMS like Joomla ?

Yes, me too.  
Can anyone point me to the documentation referenced on the movu.ca home page?  
I would like to see what it looks like as a plain cms without the social bits, 
or maybe making some of it available.

To add to this thread,  I've installed Movuca, instant press, and plugin wiki,  
just to check them out.Although I'm not clear when a wiki becomes a cms, or 
the other way around.

Anyway, having all of them is great.  I have to make a choice for my pet

[web2py] Re: Newbie Alert: A flow chart of how things happen

[pbreit]

I'd suggest running through the "Overview":
http://web2py.com/books/default/chapter/29/3

If I understand correctly, you're not going to see "event driven 
programming". Basic web programming is "Request > Build Response > Send 
Response back to the User".

Re: [web2py] Dynamic model creation

[pbreit]

I'm not sure it's a Web2py limitation so much as an SQL limitation. You 
actually might be able to implement dynamic schemas in Web2py I guess by 
building your define_tables() on-the-fly but it doesn't sound like the best 
idea (you'd need to be doing a lot of unpredictable migrations).

But dynamic schemas are where NoSQL DBs really shine. There's some degree 
of support for Mongo in Web2py but I think it's fairly preliminary.

You could also program directly to Mongo but you'd lose DAL features (which 
might not be too bad).

[web2py] Re: uWSGI + Cherokee + web2py - a howto.

[Leopold]

Hello everyone, I'm in need of help to get this configuration (ubuntu + 
cherokee + web2py + uwsgi) running.
I used a very similar how to on this (this happened many months ago) and 
everything worked perfectly.

When I followed the instructions I had an ubuntu version with python 2.6 
but when I decided to upgrade to ubuntu 12.04 (python 2.7) the problem 
started. Initially the problem was the 503 Service Unavailable message and 
by looking at the logs it was obvious the change in python version was 
responsible for this since uwsgi was saying libpython2.6.so.1.0 missing or 
something like that. So I reinstalled the latest uwsgi built with python 
2.7 and the 503 error went away. However I still couldn't get my web2py app 
to show, I now get:

*uWSGI Error*Python application not found

I searched all over for this but I can't find how to fix it. I'm posting 
the cherokee error log and the uwsgi config file hoping you can help me.

Well, I looked at the code in gluon/sqlhtml.py
the SQLFORM class @staticmethod grid() does not take submit_button or
_submit_button and doesn't (so far as I can tell) accept *args or
**kwargs parameters. Further, the code itself for handling the edit
case creates a SQLFORM and passes in the submit_button parameter with

[web2py] SQLFORM.grid - questions/suggestions

[Doug Philips]

I know that SQLFORM.grid is marked experimental and thus I shouldn't
expect it to be as refined as some of the other parts of web2py, but
I'm hoping that also means it is still a bit open to adjustment?

SQLFORM.grid has saved me a ton of work, but there are few things I
wish it did slightly better.

1. The 'Add' button's button text seems to be hard coded. I'd like to
make that a parameter with a default value of 'Add' (in some forms,
'Add' is ok, and in others I'd like to set it to something else, such
as 'New Proposal').

2. The submit button's button text on the edit forms for a row (the
ones you get when use the 'edit' button from the tabular view) is hard
coded to 'Submit'. I'd like to suggest changing it to a parameter and
making the default value of that parameter be 'Save Changes'.

3. Would it be OK to add a "separator" parameter, as in the base
SQLFORM? (I've gone into the code to just change the hard coded
value.)

I'll make bug tracker entries (one or three) unless the current
behaviour can't be changed.

Thanks!

[web2py] Re: web2py: crud interface and query strings

[Joel Robinson]

Thanks for the reply. I tried you sugestion but still no joy. I haven't 
included all the code 
so that the examples as simple as possible. I can try to attach some of my 
code and send it
to you if you wish. 

If you add some code such as:
else :
record = 'No part number URL should read 
"update_inventory?partnum=something"'
return dict(record=record)

then it returns that message when you submit an update, but the database is 
still not being updated.

[web2py] Re: web2py: crud interface and query strings

[Anthony]

What are you returning in case no rows are found? Also, you can instead do:

row = db(db.invent.partnum == request.vars.partnum).select().first()
if row:
etc.

.first() returns the first row or None if there are no records.

Thanks for the reply, but its still not working correctly. I changed the 
code to the following:

if rows:
row = rows[0]
record = crud.update(db.invent, row.id )
return dict(record=record)

with a URL like:

http://localhost:8000/GeorgesTV/qrinv/update_inventory?partnum=LAMP-4

I will get the correct web page, but when I change a value and hit the

a page that says "None". If I reload the page the values are unchanged.  
Nothing was updated.

 I thought maybe the request variable wasn't getting passed correctly when 
 updated so I made the following change:

 session.partnum = request.vars.partnum
 rows = db(db.invent.partnum == session.partnum).select()

 which didn't help either, but I then noticed that if I tried to pull up 
 the update_inventory page now without the query string
 it would come up since session varible was already set and it would update 
 correctly!

 I was eventualy able to get it work more or less how I wanted by writing a 
 page whose only function was to take the 
 query string set a session variable and then redirect you to the 
 update_inventory page. But I worry that using session varibles
 may cause unforseen problems eventualy.

 So what I would like to know, is this a bug I've found or am I going about 
 doing this incorrectly? Could someone explains
 what happens when you use crud.update and why I get this error when I try

[web2py] Re: Dynamic model creation

[Anthony]

Once you specify a given type of object, will its schema always remain the 
same? If so, you should be able to dynamically generate the DAL table 
definition and have the DAL create the table. However, if you need to make 
arbitrary dynamic changes to the schema within a given class of object, 
you're probably better off with a document database like MongoDB. The DAL 
does have an experimental MongoDB adapter, but I'm not sure how complete it 
is and whether it could easily handle this use case -- if not, though, I 
think MongoDB is fairly easy to work with natively via the Python driver.

[Joel Robinson]

Thanks for the reply. I tried your sugestion but am still getting an error, 
though a different one:

Traceback (most recent call last):
  File "/home/joel/Source/web2py/gluon/restricted.py", line 205, in restricted
exec ccode in environment

, line 
131, in update_inventory
record = crud.update(db.invent, row.id )
UnboundLocalError: local variable 'row' referenced before assignment

Just to be clear the page is coming up initialy. This error only happens when I 
click
on the submit button. Thanks again for your help.

I think it would really help for you to get the web2py book and read 
it.  It does a great job explaining the flow of control and how data 
gets passed around.

[web2py] Re: Errors creating/reading tickets

[Chris]

Following up on some of the clues others have suggested -- I have this 
problem when running web2py version 1.99.7 on Red Hat Enterprise 6.2 (very 
similar to CentOS) and mod_wsgi with Apache.

Happy to provide copies of the error tickets if that would help with 
troubleshooting -- ?

Hello Johann,

thanks for your response.
But I'd like to have two buttons per item, and I wonder if this could be
implemented.
At the moment the lambda function returns one link for an item resulting
in one button per item.

I can not figure out, what to pass, if I want to have several buttons
and I wonder if this is supported at all.

Kind regards
Cornelius

[web2py] Newbie Alert: A flow chart of how things happen

[Omar Ali]

I'm a total newbie. I have programmed extensively during the VB days (event 
driven programming) (I know, you'd hardly call that programming!) so ... 
Web programming is taking a toll on me.

Could someone explain to me the dynamics of web2py programming in a way 
that an event driven programming dude can understand, maybe using analogies 
and such..

Re: [web2py] Dynamic model creation

Hi pbreit and thanks for the reply.
So web2py is not the preferred way to go as DAL needs a scheme? Is there no
way to integrate DAL in a dynamic way?

There will be a button for each item in links if you use links=links in
arguments for SQLFORM.smartgrid.

Hi Paolo,
I'm afraid I can't reproduce it anymore.  The caret is there and I now see

I've just put your two files above back on my old app and it still works

After that small diversion,   I'm still looking forward to seeing your

Hi,
is it possible to add more than one button to a SQLFORM.smartgrid?

At the moment I would add one button like this...|
links = [lambda row: A(T('Add a contact to this
customer'),_href=URL("customer","add_contact",args=[row.id]))]

[web2py] Re: Anyone using BootSwatch with new web2py layout

[LightDot]

Yes, I thought it might be a feature, not a bug :)

I was just testing the bootstrap integration and capabilities, so no great 
harm. Thanks for clarifying.

I'm afraid you can not do it. The first item in the dropdown menu (having 
class="dropdown") can not contain an URL. The structure of the dropdown 
menu is as follows (taken from this page 
http://twitter.github.com/bootstrap/components.html#navbar):

Adding dropdown menus

Adding dropdowns and dropups to the nav is super simple, but does require 
the use of our javascript 
plugin
.

Re: [web2py] niphlod tvseries error

[Niphlod]

There are a few places here and there stating that web2py supports python 
2.5 , 2.6 and 2.7, preferring 2.5 .

I contacted Massimo the last week just about that the binary 
distribution with a recent python version could enable some new features 
that are in stable. Builds against 2.7 seems to work ok with small 
modifications, and I sent Massimo my patches for it.

I'm pretty sure that for the 2.0 release binary version will be built 
against python 2.7 ...

 yeah, forgot to mention in the main page that w2p_tvseries won't work

 BTW, the function this line is in is not used for the moment, but a 
 one-line fix will avoid the error, so as soon as possible I'll release an 
 update.

 @all: if you want to discuss it further, maybe this can be a right

 move to github's pages ;-)

Re: [web2py] niphlod tvseries error

[blye]

thanks again
I am curious.. 
in light of above, my web2py runs very fine most of time but newer apps are 
having this issue
why does the web2py distrib bin version have py 25 dll etc

Are there any references to this issue in the lit or books
Is a new main thread worthwhile in this regard?

 this is a python issue you can solve with this (if not running 2.7)

 return UL(*lis, **{"_class": 'nav'})

Re: [web2py] Re: Embed youtube videos

[pbreit]

You could write a little but of code to figure out if the user put in the 
whole URL or just the code and then just save the code.
