[web2py] Fetching a single field from multiple rows in gluon.sql.Rows as a tuple/list?
Hi, assuming that I have a Record table with a field called Name in the database (all also that there are a bunch of other fields for that table). Assume that I make the following query: Rows = db().select(db.Record.ALL) Is there a way to directly (with one line without having to iterate through each row and create the tuple/list manually) fetch the Name field for all the rows in a tuple/List? -- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: Translate change password
Looking at gluon/tools.py (around line 600:) I see all the messages,
labels, and strings that can be customized.
For a start, you could copy this entire list into your db.py (or
wherever you enable auth), and at a minimum reset each such as this:
auth.messages.submit_button = T('Submit')
I seem to remember something about this not being done in gluon
because T() is not necessarily known there...
Hope that helps.

[web2py] Re: Fetching a single field from multiple rows in gluon.sql.Rows as a tuple/list?
Thanks for both replies :). So, if ``db().select(db.Record.Name)`` acts like a tuple, then I can do something like this: Names_in_db = db().select(db.Record.Name) for Name in List_of_names: if Name in Names_in_db: #Update logic goes here else: #Insert logic goes here Also, I have another question: The belongs member function for DAL.Table.Field allows you to isolate rows for which a particular field is in a given set of values. Is there a short direct way to specify that you actually want to isolate the rows for which a particular field is in the complement of the set? Likes (for example... actually, its pretty much what I'm trying to do in my code): db(db.Record.Group_id==ID (! db.Record.Name.belongs(List_of_names))).delete() Note: The above syntax is not correct and gives an error, but it illustrates what I'm trying to achieve.

[web2py] Re: web2py book and softcron
Exactly, hardcron checks once a minute, softcron checks on each page load. The 'check' is calling a function or two and comparing a file's timestamp, so not *that* much more expensive.

[web2py] Re: Fetching a single field from multiple rows in gluon.sql.Rows as a tuple/list?
Ah, I found the answer to my question in the post:
http://groups.google.com/group/web2py/browse_thread/thread/cf8ad3e94fc9f1da/59261d38a98ece4d?lnk=gstq=belongs#59261d38a98ece4d
So, I guess I'll modify:
db(db.Record.Group_id==ID (!
db.Record.Name.belongs(List_of_names))).delete()
To be:
db('NOT %s' % (db.Record.Group_id!=ID |
db.Record.Name.belongs(List_of_names))).delete()
Got it.

So, if ``db().select(db.Record.Name)`` acts like a tuple, then I can
do something like this:
Names_in_db = db().select(db.Record.Name)

if Name in Names_in_db:
#Update logic goes here
else:
#Insert logic goes here
Also, I have another question:
The belongs member function for DAL.Table.Field allows you to isolate
rows for which a particular field is in a given set of values.
Is there a short direct way to specify that you actually want to
isolate the rows for which a particular field is in the complement of
the set?

in my code):
db(db.Record.Group_id==ID (!

illustrates what I'm trying to achieve.

So lets repeat some steps to see how this happened.

- Refresh appadmin
- db.import_from_csv_file(open('/home/dumps.csv', 'r'))
export / import use csv.reader / csv.writer ---
DAL import_from_csv_file calls Table import_from_csv_file --- you
should look at how these setup, and if that's causing the problem.
The table ID's triy to be re-numbered - it might be that a reference
is being missed (if you have a reference field defined as an integer,
I would suspec that - otherwise, might be a bug in the way the import
happens).
Basically - look at the csv file manually, and then try to find the
reference that is potentially causing you the problem - figure it out,
and fix it (I know that's not helpful in itself, but that's the level
you need to look at, at this point).
- Yarko
- Refresh appadmin
- Raises - Undefined Exception - get record id.
- bad_reference = db(db.category.parent == bad_record_id).select()
- len(bad_reference) = 1
- print bad_reference.parent == 4057
- print db(db.category.id 0).select(orderby=~db.category.id).first()
category.id - 4053 # this is the highest category in databases
category.name - sports

[web2py] crud update with represent
Hi, As I understand, when crud.update(...) creates a form it pulls the values of a given record into the form as a string. If the field is a reference to another table, then this shows up as a number. I would like to instead show the name of the record instead of the id. I have a represent function set in the data model, but that is only used on crud.select(). So, my question is how can I get the crud.update(...) form to render the record values with according to the represent function specified by the represent function of the field. Code below: #model db.define_table(food, Field(desc, string,) ) db.define_table(ate, Field(food_id, db.food, represent=lambda x: db(db.food.id==x).select().first().desc ) ) #controller form=crud.update(db.ate,ate_id) Thanks, Avik -- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Using Ajax to display detail from a list
What I want to do: have a list of items displayed; when one is clicked,
more detail is shown (via an Ajax call) in a defined detail area.
Problem: the web2py ajax call takes three parameters: a controller action,
one or more field ids, and a target DIV. My controller action needs to
identify which row has been clicked on, so I need a hidden field per row
that holds the row number. Because all field ids need to be unique, I
actually have to build a dynamic name for the row id (eg,
id=row_{{=row.number}}, name=row_{{=row.number}}), and - even worse - my
controller action doesn't know the name of the field passed, so it has to
parse response.vars to find it.
Web2py and Python in general are so well architected that I know there
must be a better way. Could someone point it out, please?
Thanks.

Re: [web2py] Re: psycopg2 problem
So mod_wsgi will not let you print, try this (before your db=DAL(...) statement)
import sys
tmp_file = open('/path/to/a/writable/file.txt', 'w')
tmp_file.write(sys.version)
tmp_file.close()
db = DAL(...)
Try and access default controller (you will get an error, but now we
have a file) Open up the file, and make sure the version corresponds
to the one your shell is using.
Probably not the most elegant way, but its quick.

Re: [web2py] Using Ajax to display detail from a list
I usually do something similar.
Even to the extreme of my td have an extra column.
So My id usually looks like
id=tablename_recordid_column
And in my controllers I parse this as
tablename, record_id, column = request.vars.id.split('_')

What I want to do: have a list of items displayed; when one is clicked,
more detail is shown (via an Ajax call) in a defined detail area.
Problem: the web2py ajax call takes three parameters: a controller action,
one or more field ids, and a target DIV. My controller action needs to
identify which row has been clicked on, so I need a hidden field per row
that holds the row number. Because all field ids need to be unique, I
actually have to build a dynamic name for the row id (eg,
id=row_{{=row.number}}, name=row_{{=row.number}}), and - even worse - my
controller action doesn't know the name of the field passed, so it has to
parse response.vars to find it.
Web2py and Python in general are so well architected that I know there
must be a better way. Could someone point it out, please?
Thanks.

Re: [web2py] Re: psycopg2 problem
And to triple make sure... from the shell printing sys.version gives
exactly the same, date, revision, GCC version ?
mod_wsgi was compiled with the same version of python installed?
So just to make sure you only get the GlobalName when you access
web2py through mod_wsgi ?
tburg...@***-dev:~/Applications/web2py$ python web2py.py -S welcome
db = DAL('postgres://user:p...@localhost:1234/database')
Correct?
and

[web2py] Re: response.headers web2py-component-command is being cut short
This means that any script included in the returned ajax call data will be evaluated (run) after the target element is updated but the script itself will not be part of the target. If the returned data is guessed by jQuery as not being 'html' this does not happen. Massimo, can this explain what you have experienced?. Also note that the 'success' function runs before the 'complete' function in web2py_ajax_page, I am not sure if you have those two reversed. Denes.

5432/appdb') gives a FATAL: no pg_hba.conf entry for host
127.0.0.1, user postgres, database appdb, SSL off but this is a
different issue that I can sort out later! It is still accessing that
postgres server to get that error, which web2py isn't.
import psycopg2 works perfectly.
Seems like web2py's dal.py module cannot find psycop2 even though
command line python can, but I have no idea why. Path probs? I'm
clueless!

If cron is being used only for something relatively simple, say expire_sessions.py, how about a kind of 'cron lite' that runs its tasks in the context of an application rather than spawning an entirely new instance of python+web2py to do the work? At the point where softcron is invoked, at the end of a request, if we're running in litecron mode, process only the crontab file for the current app, and run the cron tasks more or less as if they were models (that is, exec in environment).

Somod_wsgi will not let you print,
Not true.
For older versions of mod_wsgi if you use 'print' you need to redirect
it to 'sys.stderr' is all. This is because using sys.stdin/sys.stderr
in a WSGI application is not portable.
Because though people are lazy and wouldn't fix their code and instead
just want to blame mod_wsgi and say it is broken, more recent mod_wsgi
versions don't try and make people write portable code any more and
allow them to hang themselves by using 'print' to sys.stdout.
A post from a year ago about this can be found at:
http://blog.dscpl.com.au/2009/04/wsgi-and-printing-to-standard-output.html
So, use mod_wsgi 3.X and there is no restriction.

Yes, you have to define_table before web2py can use it.
When accessing an existing table, i.e., a table not created by web2py
in the current application, always set migrate=False.
I don't know if table names are case sensitive in Oracle.

[web2py] Re: psycopg2 problem
Yeah, it's all spelled fine (not like I typed it there, sorry!) and
the database exists. Obviously if web2py was connecting to PostgreSQL
it would give a database not found or a cannot write to database
error or something, not a python cannot find psycopg2 module.
I think now that the question that needs answering is why can't WSGI
web2py see psycop2 even though terminal web2py can...? I'm not gonna
say BUG, but I can't work out what Im doing wrong!

Re: [web2py] Re: Validation per object
I actually have an example for this kind of form. Say I have two Records, Person 124 and Person 532. Well come to find out, record 124 and 532 are the exact same person who signed up twice. I want to merge the two records together and leave with just one, but oh noes 532 has more up to date info than 124. So I want to display both records, side by side, with some radio buttons A and B for each record. If the radio button has A as a value when it comes in, I take from Record A( in this case, Person 124)., If the radio button has a value of B, I take record 532. So in this case, I cannot use SQLFORM (I could, but its much easier to just use a manual form, and manually validate the request.vars) -Thadeus On Thu, Apr 1, 2010 at 6:34 PM, Yarko Tymciurak resultsinsoftw...@gmail.com wrote: On Apr 1, 5:04 pm, carlo syseng...@gmail.com wrote: sorry for this out of sync answer but though I managed some tricks to tackle the (problem of) validation in pure html forms during these years, I would be curious about an answer to Mengu's request of showing how to make validation with manual forms.

As it stands, it seems to me to be missing some key information / motivations.

Re: [web2py] Re: psycopg2 problem
It still must be a problem with the site-packages.
And I wonder if it has something to do with the fact you had
problems with easy_install.
I would try
apt-get remove python-psycopg2
then look in your site-packages, make sure to remove ALL instances of
psycopg2 egg or src files. Also check your local user instance of
python modules.
Then once you are sure its clean, attempt to reinstall with apt-get.

Yeah, it's all spelled fine (not like I typed it there, sorry!) and
the database exists. Obviously if web2py was connecting to PostgreSQL
it would give a database not found or a cannot write to database
error or something, not a python cannot find psycopg2 module.
I think now that the question that needs answering is why can't WSGI
web2py see psycop2 even though terminal web2py can...? I'm not gonna
say BUG, but I can't work out what Im doing wrong!

A really basic check: have you created the database, appdb, and
given it no-password rights to user posttgres (? is that use spelled
correctly???) for at least read and modify?

import psycopg2 works perfectly.
Seems like web2py's dal.py module cannot find psycop2 even though
command line python can, but I have no idea why. Path probs? I'm
clueless!

And to triple make sure... from the shell printing sys.version gives

mod_wsgi was compiled with the same version of python installed?
So just to make sure you only get the GlobalName when you access
web2py through mod_wsgi ?
tburg...@***-dev:~/Applications/web2py$ python web2py.py -S welcome

Correct?
and

So mod_wsgi will not let you print, try this (before your db=DAL(...)

Try and access default controller (you will get an error, but now we
have a file) Open up the file, and make sure the version corresponds
to the one your shell is using.
Probably not the most elegant way, but its quick.

1) He said he gets the error when I try to access default

2) He did not say I try to access psycopg2 from my controller.
I take what he said to mean (statement 1) he cannot connect to
postgres with web2py. Perhaps he really ment statement 2, in which
you
are correct.

that is not the point / problem here;
anyway, python web2py.py -S welcome, and an attempt to import
psycopg2 from that shell will show that you can import it fine
from
the web2py app level; gluon.dal imports it, and your app
doesn't get
to see it for a reason.

[web2py] Import modules not working
Hi
I tried to install the clienttools.py module found here
http://www.web2pyslices.com/main/slices/take_slice/8
However when in my application controller I try to import the module
by doing the following:
clienttools = local_import('clienttools')
page = clienttools.PageManager(globals())
event = clienttools.EventManager(page)
js = clienttools.ScriptManager(page) # javascript helpers
jq = clienttools.JQuery # don't instantiate, just to shorten
I get the following error:
Traceback (most recent call last):
File C:\web2py\gluon\restricted.py, line 173, in restricted
exec ccode in environment
File C:\web2py\applications\mlinks/controllers/
backend.py:GenerateLinksBetweenSites, line 26, in module
File C:\web2py\gluon\compileapp.py, line 258, in lambda
local_import_aux(name,reload,app)
File C:\web2py\gluon\compileapp.py, line 196, in local_import_aux
exec(import %s as mymodule % name) in env
File string, line 1, in module
ImportError: No module named applications.mlinks.modules.clienttools
the clienttools.py file is in the modules directory of my application.
What am I doing wrong?
Thanks

PS: I am running on the gae locally (devserver)
