Re: [web2py] SQL Server Connection String Please HELP
I had big problems with the connection to a mssql server.
My working connection string is this:
mssql://DRIVER={SQL Server};SERVER=HOST\DATABASE,PORT;UID=USER;PWD=PASSWORD
On Wednesday, April 24, 2013 11:16:58 PM UTC+2, Tim Richardson wrote:
b = SQLDB('mssql://username:password@localhost:portnumber/databaseNAME')
Can someone give me a some examples or link to any information where I
can see how a simple program connects to a SQL SERVER DB and selects a few
records from a table and displays them...
I have been researching to find examples, but I have not found anything
specific to my problem,
this is how I access a local server. The machine is server-win2003.
db = DAL('mssql://*user*:*pass*@server-win2003\hcnsql07/vcidat')
In this case, the SQL Server has an instance name of hcnsql07
and the database is vcidat
Probably that part of the connection string is the trickiest (the server
name and instance). I use Microsoft SQL Server Management Studio to connect
to the database to prove to myself that I know exactly the name of the
server. In case you didn't know, there are free Express editions of
Management Studio for download.

You need to use some ajax file upload mechanism. Here's an example: http://www.web2pyslices.com/slice/show/1438/ajax-file-upload-in-loadweb2py-components If you follow that example, I recommend you put the javascript directly on the webpages that will use it so you don't have to deal with versions of web2py_ajax_page, etc. that are different from the regular web2py ones elsewhere.

[web2py] Re: Connecting to remote database - ERROR', '42P07', 'relation mytable already exists
you may have the mytable file but the connection string when it was
generated was different (there's a hash in front of all .table files just
for this). Anyway, if you're sure that you don't need to trigger any
migration, just set fake_migrate_all=True for one request and all .table
files will be regenerated without trying to do anything to your database
tables.

The funny thing is when if i access the post normally and not as a
component the file is being uploaded and but as a component as shown in the
code above, the image is not being uploaded and the database field for
image is empty but the name of the picture is added.
Any thought on this or its by design that its not working!?

[web2py] Re: sqlform custom fails to hide errors
Technically, hideerror is an argument of the .accepts() method of FORM (and therefore SQLFORM) -- it is also an argument of .validate() and .process(), which ultimately call .accepts(). Because of the way it is implemented, you can also pass hideerror directly to FORM() and SQLFORM(). It should work either way. If it's not working with form.process(), please show your code.

[web2py] Datetime calculations and some genearal functionality advice
So for the website that I'm developing I want my users to be able to set
availabilities, and after they have expired, I want them to be set as
inactive . Also another feature would be validating the form to make sure
the start and end time contained a vaild availibility (ex. the start time
the end time). Then after this, I would like to create a list of all of the
current available users at this current moment.
Here's my model
#user availability
db.define_table('user_availability',
Field('user_id', 'reference auth_user', default=auth.user_id, readable=
False, writable=False),
Field('start_availability', 'datetime', requires=IS_DATETIME()),
Field('end_availability', 'datetime', requires=IS_DATETIME()))
Controller
form_create_user_availability = SQLFORM(db.user_availability)
if form_create_user_availability.process(formname=
'form_create_user_availability').accepted:
session.flash = 'Availability Added'
redirect(URL('user/profile'))
elif form_create_user_availability.errors:
response.flash = 'Error'
Anyway, any help or advice on how to achieve this would be awesome !

in the library that saves the data is:

binary = a2b_base64(raw_epl)

I call the function using:
shipment.save_label(open('label.gif','wb'))
where shipment is a shipping label object produced by the library.
Does web2py do something that would corrupt the header?

It's not working because you're doing something wrong. Probably because

with your LOAD.
{{extend 'layout.html'}}

This is correct but does not mention that the contents of the additional field are only copied to the corresponding local field when the user logs in the first time, ie when the local user is created. When the original field (in the CAS provider) changes and the user later logs in locally the contents of the changed field are not copied again.

[web2py] Query doesn't select the proper range
I've got a query which looks like this: (db.tracking.number = 0) (db.tracking.number = 22000) where number is an integer. And this should select everything with numberbetween 0 and 22000 but it doesn't. For example, if I set the query to just (db.tracking.number = 0) as expected it grabs anything with a number greater than or equal to 0 and I can see all the data. However, if I set it to (db.tracking.number = 250) it grabs everything greater than 250, less than 1000, and will also pick up numbers where if a trailing zero was added, it would be within the range (ex: 26-260, 27-270, 28-280, 29-290, 30-300, ... ). I have some strings formatted like this: X# which I use re.sub to remove characters and then use int() to convert the remaining number to a int before ever being put into the table. I've checked to make sure everything really is an integer before going into the table and it all seems to be OK. I'm not sure if this is a python quirk, SQL quirk, or a web2py quirk. Any suggestions?

As long as web2py goes, it issues a select to your database engine and that one is responsible for picking up the records you want. Is the select generated by web2py correct ?

[web2py] Re: compute field insert/update
Ah silly me, I totally overlooked the default functionality. And those triggers seem useful.

[web2py] wymeditor
Does any one use wymeditor in web2py?
I downloaded version 0.5 and put it in the static folder, and included the
following tag in layout.html
script
src={{=URL('static','wymeditor/jquery.wymeditor.min.js')}}/script
and used the following function:
script type=text/javascript
$(document).ready(function(){
$('#promo_text').wymeditor();
});
/script
For some reason this doesn't turn the promo_text textarea into a wymeditor
instance.
What do I overlook?

[web2py] Re: Count and distinct
Yeah, I agree. I read the documentation and I have no clue what is happening there. Are there two people named Alex? Does 'Alex' own two items? Why is it grouping by person name instead of person id? Why is 'count' assigned as a count of person IDs, used as an argument in the select (presumably it's just an int?) and then used as an iterator (assuming the count of person IDs is 2, then it's just getting row 2?)?

[web2py] Re: Count and distinct
db.person.id.count() returns an Expression object. It generates SQL like COUNT(person.id). When it is passed to the .select(), the count is returned as one of the columns in the result. The key used to identify the count column in each Row object of the result is the count SQL itself (i.e., COUNT(person.id)), so you can access the count in each row via: row['COUNT(person.id)'] However, the __str__ method of the Expression object will also return the SQL, so you can instead do: row[str(count)] To make things even easier, if you pass an Expression object as the key to a Row, it will automatically apply the __str__ method, so you can just do: row[count] which is the method used in the book example.

Hello,
I have deployed my web2py application on Google app engine. I'm trying to
use Gatling (http://gatling-tool.org/) for load testing my web
application. Just accessing my home page (which is a static page with a few
images and links) exhausts my free quota of DB write operations per day.
On further debugging I realized that each request was creating a new
session record in the table web2py_session_appname table.
Investigating the HTTP request and response traces from my Gatling
client, I see that the client is setting the Cookie parameter
(session_id_appname) correctly in the request - same as the one sent by
my web2py app in the Set-Cookie parameter of the last response. The
SetCookie value sent back by server is enclosed in double quote (). The
Cookie sent from client also contains double quote.
The code in gluons/globals.py tries to parse the cookie value using
below line of code:
(record_id, unique_key) = response.session_id.split(':')
The record_id now contains a double quote - so the record is not found in
db and a new session record is created each time.
*I privately modified the globals.py code to use underscore ('_')
instead of colon (':') as delimiter in the session cookie - the cookie no
more contains double quote and the problem is solved.*
Please note that this problem is faced only when I use gatling; using
normal browsers (chrome, FF, IE) does not result is new session record
created each time. I think the problem is due to the way gatling is
handling double quote in as part of cookie value. Also when I test with my
local web2py instance with gatling, the problem is not faced as session
cookies which are stored as files in file system does not contain ':' and
hence no double quoting.
I don't see yet a way to modify gatling.
*My question to web2py community:*
Do you see it as a fair request to change the delimiter used in DB
session cookies from ':' to something else (e.g. _) so that cookies are not
double quoted - this will accommodate also clients which know only to
handle 'cookie version 0'.
If this is an acceptable change, where should raise my request /
contribute my changes?
Thanks and warm regards,
Aravindan.
