Web Applications - Separating DB Connections

[Burhan]

Hello Everyone:

  I am trying to find a way to extract and remove database connection
information (username, password, schema name) from the application
source. I need to do this because in my organization - for security
reasons - access to databases is controlled by a separate department;
and as such, when a solution is deployed to production - the
authentication credentials for the databases are changed (and not told
to the development team).

  Currently all development is done in Java and with that they have
the ability to publish databases as a service in their application
server; this way users can be granted access to modify the credentials
to the JDBC data source without having to edit source code of the
application being deployed.  I am looking for something similar in
Python (short of using Jython).

Thanks!

Using selenium, you can check for broken links[1]. Hope this helps.

Unfortunately our servers are Windows so neat tools like fabric (which
I
had used before on private projects) is out of the question. I am not
aware
of it being using for Windows servers successfully.

Thanks!

Printing Barcodes from webapp?

[Burhan]

Hello Group:

  I am in the planning stages of an application that will be accessed
over the web, and one of the ideas is to print a barcode that is
generated when the user creates a record.  The application is to track
paperwork/items and uses barcodes to easily identify which paper/item
belongs to which record.

  Is there an easy way to generate barcodes using Python -- considering
the application will be printing to a printer at the client's machine?
I thought of two ways this could be done; one would be to interface
with the printing options of the browser to ensure that margins,
headers, footers are setup properly (I have done this before using
activex and IE, but with mixed results); the other would be to install
some small application at the client machine that would intercept the
print jobs and format them properly (taking the printing function away
from the browser).

  Does anyone have any experience or advice? Any links I could read up
on to help me find out how to program this?  Another way (easier
hopefully) to accomplish this?

Thanks for any advice.

I thought about this as an option too, but I do not have control over
the client machines, maybe I'll use this and go with the PDF idea
mentioned above.

Thanks for all the links, I have some reading to do now.
