[web2py] Debug Web2py with Wing IDE
Hi , I asked Wing support the following question: I am using Web2py framework. I saw a video that says the Wing can debug a running python code no matter if it launched it itself. When reading this: http://wingware.com/doc/howtos/web2py I see that I can only debug Web2py in a way that I need to rerun the server from Wing for each time I hit 'Debug'. Is there any better way to do it? *They replied:* *This is our recommended approach because of the difficulties reloading code in Python. Does web2py have code reloading? It's been some time since I worked with it. Or does it have a master process that spawns a new sub process when things change? django and some other frameworks work this way.* Do someone know what is the answer to these two questions?

Another thing is, when user edits the ticket, he should again see changes

Is this possible? I'm a bit confused, because LOAD works fine, but not

[web2py] Can I change a value from a form before it is processed?
Hi ,
So the situation is this:
I have table for posts - Only the user posted a message may see it
and then table for shared_posts - The user created a post may enter
user_ids here, and those users may also see the post
I don't want to add record for each share, so shared posts is defined
like this:
db.define_table('shared_goals',
Field('goal','reference
posts',readable=False,writable=False,requires=IS_NOT_EMPTY()),
Field('user_id','list:reference auth_user'),
auth.signature)
Notice that user_id is a list.
When I produce a form (with given id, so it is actually an edit form), it
shows user_id as a list of all the people registered. I don't want this.
people should not see who else is registered.
So, In the view I wrote this:
{{=shared_goals_form.custom.begin}}
{{=INPUT(_name=user_id,_id=shared_goals_user_id)}}
{{=shared_goals_form.custom.submit}}
{{=shared_goals_form.custom.end}}
And then, after being processed, the list in DB only contains one user_id
(latest).
The question is: Can I change the value of user_id input after submission
and before the process, so that it will include previous user_ids?
Thanks!
Omri.

[web2py] Speeding up the admin interface
Hi dear list, I am using web2py mainly as a JSON-RPC server and gateway to the database. As a client I use qooxdoo with asynchronous json-rpc calls to communicate between the two. I currently have in my database 74 tables, and expect the number to grow a bit in the future. I mainly use two files, the models file to define the tables and controllers/default.py to handle all the traffic. This file is ~4300 lines long. My problem is that when I try to access the admin interface, usually to use the database admin, it takes a really long time to load, and actually also sometimes hangs. In addition to what I described above, I have the qooxdoo application in the static directory, along with the framework since I need to do the development while the server is running. When I deploy the app, the qooxdoo framework won't be needed anymore (it will be 'compiled' to one minified js file). Do you have any suggestions as to how to speed up the admin interface? Or, for that matter, the server response time which is sometimes quite long? Thanks, Omri Har-Shemesh --

[web2py] Re: Watching a table for changes
Thanks for all your help! Now I understand web2py a little better :-) Since I do not want to add to each insert the appending of the function - I simply added it after creating the table in the model, and now it works well since it is being executed together with the model code. Are there good reasons not to do it? Since I use web2py mainly as a back-end to JSON-RPC calls and gateway to the database, my application is basically built out of a huge default controller and a huge model file. I don't think I would know where to put it otherwise.

This is not how web2py works -- you have to add the _after_insert function in the same request as the insert. More generally, keep in mind that your application code is executed on each request -- whatever you define in a given request is specific to that request and does not persist to subsequent requests (unless, of course, you explicitly store it in the cache, session, db, filesystem, etc.).

[web2py] db.table.insert() inserts a field with id=None but returns an id number
Hi, I suddenly came across a weird bug, where when I add a record to a specific table (it doesn't happen with other tables), it inserts the record with the id field == null, but returns a number as if it is the id. Furthermore, the number returned is close to (but not exactly) the number of records in the table (it is a little bigger than the number of rows in the table). The thing is that the highest id field in the table (which was obviously inserted prior to the bug) is 219, while the new ids generated are around 70, and the number of records in the table is 65. I am using web2py 1.99.7 dev with pysqlite2. Any advice as to how to debug this will be greatly appreciated!
[web2py] Re: db.table.insert() inserts a field with id=None but returns an id number
Additional information: after going through my revision history, it seems that the problem started after I changed the type of a field from string (didn't notice I forgot to define it as integer and therefore it defaulted to string, even though the default=0 was specified). Then, since sqlite doesn't really allow you to change the type of a column, I used Sqliteman to do that (it was critical to change the field type). What sqliteman does is essentially drop the table and recreate it with the new definitions. I'm suspecting that web2py is unhappy about this. Is there a way to make web2py happy again? I'm guessing that now the table's definition as it really is, is different from what web2py expects. Any help would be greatly appreciated!

[web2py] Sharing application across development machines - what files to synchronize from databases directory
Hey List, I am developing a database application with web2py as the server back-end, and a client application in qooxdoo, which interacts with the server through JSON-RPC. I use Mercurial as my VCS and synchronize the code from qooxdoo, the code from the controller and the code of the model (I do not use any views since it is handled by qooxdoo) using Mercurial to Bitbucket. I also added the database (SQLite) file to the repository so that I can develop on more than one machine. I do not synchronize the web2py code and the qooxdoo framework code because it will make the repository bloated and I don't really need to do that. My question is the following - which files should I synchronize in order to use the database in more than one computer? Tables are being continuously added and changed. I tried synchronizing only the database file, but then the application complained about the structure of the tables in the database. To solve it, I deleted everything from the databases directory, let web2py rebuild the files and then replaced the storage.sqlite file with the one from the repository. Is there a better way to do that? Should I add to the repository all the files from the databases directory? And a different question which occurred to me - is there a way to tell web2py to clear the database before deployment, or should I simply delete everything from the 'databases' directory and let it rebuild the tables? Thanks, Omri

In addition I found the following article of someone who explored the regexp support of popular SQL databases: http://trentrichardson.com/2008/10/23/exploring-various-sql-regex-syntax/ All in all, seems that most systems support some version of POSIX standard, except when you need to extend the SQL with a user defined function, then I guess you can chose the implementation you want.

[web2py] (Very) small improvement suggestion
Hi All,
I have an extremely small suggestion to make life a tiny bit easier - in
the beginning when starting web2py using python web2py.py there appears a
dialog box.
In the dialog box, the password field has a binding on the 'Return' to
start the server when the return key is pressed. I suggest adding a similar
binding to the port field (and maybe IP field as well), since usually the
focus is on the password field I fill it in first, and since I need a
different port and change it next and it will be very helpful if it
automatically opens the window after a return press.
the only change necessary is in the gluon.widget, around line 214 one has
to add:
self.port_number.bind('Return', lambda e: self.start())
and maybe around line 202 the same for the ip field.
Thanks,
Omri
[web2py] importing gluon to a module in the modules directory
Hello, I'm writing a module to contain some class definitions I need for my application's business logic and I would like to access gluon from my module. I placed my module inside the modules directory and import it using local_import. I want to have the classes in the module access the database (which I managed by passing the db DAL instance to the classe's constructor), but I would like to be able to check that the expected DAL object is transferred during construction of the object. To that end I would like to write something like: if isinstance(db, gluon.dal.DAL) or just if isinstance(db,DAL). I have tried to import web2py in the usual way (import web2py) - and it raised an exception - TclError: image pyimage2 doesn't exist. and opened a white triangular window without any borders that will not go away unless I close the web2py application. It does the same when I try to import only web2py.gluon.dal. I'm running on Ubuntu 10.10 with web2py version 1.94.6. Thanks, Omri

[web2py] Web2py uses the wrong database
Hello all,
I have recently come across a strange problem:
I copied my application to a different name, because I wanted to
create a branch for beta testing of my application. I emptied the
database from all my tests (using Sqliteman - btw - is there a better
way to clear the database and reset the auto incrementing fields?).
Now when I opened my development (trunk) version, I discovered that it
uses the same (clean) database as the branch. I checked that it really
is the same database by using one application to add data, and view
the data with the second app. This does not happen with the web2py
database administrator, only when I access the data through my
application.
For both applications I use the default db = DAL('sqlite://
storage.sqlite'). I am accessing the server through JSONRPC (using
qooxdoo).

[web2py] Re: Web2py uses the wrong database
I have found my problem - it was some stupid configuration problem.
But I will still want to leave the question open - What is the best way to
create a new 'clean' copy of the database file, resetting all the
auto-increment fields?
Thanks,
Omri

Hello all,
I have recently come across a strange problem:
I copied my application to a different name, because I wanted to
create a branch for beta testing of my application. I emptied the
database from all my tests (using Sqliteman - btw - is there a better
way to clear the database and reset the auto incrementing fields?).
Now when I opened my development (trunk) version, I discovered that it
uses the same (clean) database as the branch. I checked that it really
is the same database by using one application to add data, and view
the data with the second app. This does not happen with the web2py
database administrator, only when I access the data through my
application.
For both applications I use the default db = DAL('sqlite://
storage.sqlite'). I am accessing the server through JSONRPC (using
qooxdoo).
Any suggestions?
Thanks,
Omri

[web2py] datetime, DAL and JSON serialization
Hey, I have a problem with datetime json serialization. I am using the DAL with sqlite, and accessing web2py using JSONRPC. Today I started getting an error when trying to pass datetime fields back to the client. I haven't changed anything in the code for the routines, but it seems that the DAL returns a datetime object which is not JSON-serializable. Has anything changed recently with the DAL? I don't think I have changed any configuration properties on my database - but could this be a reason for it suddenly stop working? Thanks for the time and great work on web2py! Omri
Re: [web2py] Re: UnicodeDecodeError: 'ascii' codec can't decode byte ...
sorry for the stupid question - but how can I call the print data function
inside a function that is called through JSONRPC? where will I see the
output?
in case it helps - I know that at least I get the two fields that I sent,
because the last line (where I name them specifically) works.

[web2py] Small suggestion regarding auth.add_membership
Hello all, I used auth.add_membership today for the first time, and I realized that the add_membership function adds a membership also if the user already has this membership. Wouldn't it make more sense if the function first uses the has_membership function to check if the user is already a part of the group? Thanks for the great work with web2py! I love it :) Omri
Re: [web2py] Re: UnicodeDecodeError: 'ascii' codec can't decode byte ...
I should have thought about that.. the result from the print data function
is:
{u'textfield': u'Viele Umlauts:
\xe4\xe4\xe4\xfc\xfc\xfc\xdc\xdc\xdc\xd6\xd6\xd6\xe4\xe4\xe4', u'name':

for the following data sent:
data = {

[web2py] JSON-RPC best practices
Hello All, I'm writing a web application using qooxdoo as the client framework and web2py as the server. Almost all of the communication between the client and the server are done through the JSON-RPC service. Since I found myself writing @service.jsonrpc functions by the dozens, I was beginning to wonder what would be considered as best-practices. Should I write a very general function that basically exposes the database to the client side? Should a write many small functions, each wrapping a database call (perhaps sometimes also doing some calculations in the background)? Should I opt to transfer large amounts of data at each JSON-RPC call (to minimize server calls), or only ask for the data when needed? This web-application is intended to be internal to my company, with no more than 30 users, and probably no more than 10 simultaneously. Any thoughts/opinions/discussions are welcome :) Cheers, Omri
[web2py] Re: 'DEMO_MODE' is not defined
I came here to report this bug as well.
I did a workaround - it comes from the beginning of the appadmin.py
file.
For the meantime I put the if DEMO_MODE: inside a try..except block.
I'm not sure this is robust but at least it works:
try:
if DEMO_MODE:
response.flash = T('disabled in demo mode')
redirect(URL('default','site'))
except:
pass
hope this helps,

[web2py] Validators with Dependencies
Hello,
I'm writing a relatively big database application. A small part of it
requires me to handle lists of values, where every list can only exist
once, and where each item in the list can only exist once (but
different lists can have items named the same way).
A simplified model is:
db.define_table('lists', Field('name'))
and
db.define_table('list_items', Field('list',db.lists), Field('name')).
(there exists more fields but they are irrelevant to the current
case).
I am now writing an interface to define new lists. I would like to use
SQLFORM to generate the forms required. I would like to use the
validators IS_NOT_EMPTY() and IS_NOT_IN_DB() to make sure there will
not exist two lists with the same name. The problem is that I would
also like to make a similar validation on the items of the list, but
to restrict the IS_NOT_IN_DB() to a set containing the list items.
In the book it gives an example using SQLFORM.factory() on how this
should be done, but when I simply use SQLFORM(db.list_items) I don't
know how to access the different fields to add a requires validator in
the action.
I've tried looking in the book and the group but was unable to find a
way to do so.
Thanks,
Omri Har-Shemesh
