I am writing a prototype program whose aim is to collect bookkeeping
transactions in a Database ( Gadfly).
After creating the table I create the variables with
varAmount = StringVar()
I then create labels in Tkinter to ease the input of data.
With a function
def treatment ():
requete = "insert into transactions ( date,amount,,.. ..)
values(......) "% (varDate.get(),
varAmount.get
I transfer data from the labels in Tkinter into the Database at the end
of the program
with a button named "End" . I print the Database with print cur.pp().
No problem up to now but then I try to use a select command:
cur.execute ("select sum(amount) from transactions"). I get
Sum.amout.trans action
=============== ==
100-10.5.......
instead of 110.5
It means that the select command does not add but concatenates the
different amounts. Why ?
Many thanks if you can help me.

Maybe you want to use DoubleVar or IntVar here?
With a function def treatment (): requete = "insert into transactions ( date,amount,,.. ..) values(......) "% (varDate.get(), varAmount.get
Or float(varAmount .get()) |
int(round(100 * float(varAmount .get()))) here
cur.execute ("select sum(amount) from transactions"). I get Sum.amout.trans action =============== == 100-10.5.......

Sounds like you selected columns are strings, not numbers.
Remember '123.5' + '-23' is '123.5-23', while 123.5 + -23 is 100.5
You need the amount column of the transactions table in the gadfly
database to be a numeric type, not a string type.

I haven't been keeping up. Is Gadfly still in development?
Thank you for your help. I have changed StringVar in IntVar and it
works! I didn't know that IntVar (as StringVa) were Tkinter Widget
variables! (It is important to read the doc!) I made another mistake
in the value definition. I'have changed '%s' in %d and it goes
perfectly well.
It could be useful for me to change of DB ? Which one ? Postgresql or
another ?

You're welcome.

Well, if gadfly is serving you well, you might as well stay with it.
Python 2.5 comes with sqlite3, which might well be a nice small step.
I find Postgresql to be a real solid DB, and a company I've been talking
with likes MySQL -- which finally has transactions (one of my personal
requirements before I'll call a DBMS "real").
Really, you should decide what you want the DBMS to do, and try to get
those requirements out; you'll get better advice.

I always find this question a little
irritating -- gadfly is perfect the
way it is :). If it ain't broke don't
fix it. At least until the python guys
make another non-backwards-compatible
change that makes a patch necessary
(speaking of things that irritate me...).
Seriously, there are a few problems
that could be fixed that I can
think of, but mostly it works for what
it is -- why are people so concerned
that it's not changing?

I didn't mean to be irritating and I wasn't concerned about it not
changing but I could probably have stated the question a little better.
For some reason I thought it was a dead project so maybe "still being
maintained" would be a better statement. I dunno.

You're not the only one. Why do I keep seeing "gadfly...d ead"
in the same sentence?
What if it doesn't need maintenance? Does that make it dead?
No offense to you personally, you are just repeating what
everyone else has been saying for years for reasons that
totally escape me. Several times people have suggested that
gadfly be added to the python standard library and then the
question comes up... who will maintain it? And I answer I'll
maintain it if anyone finds serious problems with it and then
a few months later I hear that it was decided that gadfly was
a dead project. This has been going on since about '97.
It's irritating and tiresome. Sorry, I'm grumpy today.

Hi Everybuddy,
I am having a little problem I can not find a solution for.
I am trying to use the SQL-LIKE statement in gadfly. After googling
around I found out that it is not supported, and that on is supposed to
use a regular expression. All great, but there is nowhere a reference
to be found on how to do this. No examples, no nothing, just the
comment to use regular expressions.

Hi,
i have a webserver with (approx.) the code below, but whatever i do
the html code sent to the browser stays the same.
The strangest is, if i insert a local variable in the class which is incremented
upon each call to self.render_GET() and append it to the html code, it
increments correctly on the browser. Could it be a probem with gadfly?

Hello
I've got problems while using py2exe, because of a module I'm using : gadfly
In fact, I had the same problem with Pmw, and the solution was to create a
single file Pmw.py which contained all the parts of the original module, and
to put it in the project's main folder.
So, I'd like to make a "freezed" version of gadfly, in order to create a
fixed win32 exe. But it's more difficult than with Pmw... so does anyone
know another way...
