Encrypt/ Decrypt password
Hi,
I have user add/edit forms.While creating a user I tried the following
method to encrypt password and stored the encrypted password in the
table.
def self.sha1(pass)
Digest::SHA1.hexdigest("#{salt}--#{pass}--")
end
But when I try to edit the page I get the encrypted password in the
password field instead of the decrypted password. Is there any method
to decrypt

Error Handling
Hi,
I am doing a project on invoice. For that I have to use a page both for
crating new invoices and for updation of existing invoices. The problem
is that when an error occures, I can''t maintain the same page for error
correction. How can I redirect it from the controller ? Or can I display
ruby errors before submit of the page in ruby?
Thanks..

Gruff gives font-related error
Hello Railslist,
I''m trying to get Gruff running on OSX Tiger (intel) with edge Rails.

dependencies, or so I believe. (I''ve compiled them from source mostly,
following a recent tutorial for Rails and ImageMagick on Intel Macs)
While following the sample on the Gruff downloadpage (the one with the

How can one use GRUFF with locomotive ( I guess there is a wider question here, also)
Hi:
I love Locomotive and use it exclusively for my rails projects. I''d
like to install GRUFF and give it a try (a graph image creation
package). I know I can do sudo gem install gruff from the command
line for normal ruby and rails. How do I make gems available to
Locomotive?

Gruff with PDF::Writer
Hello all
Has anyone managed to embed gruff graphs into a PDF document using
pdf::writer?
The easy way (as far as I can see) would be to just save the gruff graph
as a temporary file then read that file in pdf::writer. I was wondering
if anyone had managed to get them working together directly?

Gruff Charting Question
I am using Gruff to chart 2 sets of data and have run into a problem,
the numbers between the two sets are so far apart that the first set
appears as a mostly straight line at the top and the second a mostly
straight line at the bottom.
Is there a way to set the min/max vertical column values so that I can

Have a quick Gruff Graphing question
I have some graphs and everything is working great, but I''d like to set
a minimum height so to speak on the vertical scale. Is there a method
to do that with Gruff? I''ve tried looking through the docs but can''t
seem to get it to work.
So for example, if the highest datapoint in my graph was say 500, is it
possible to have the minimum vertical scale on the left set

Need some Gruff graphing help - custom dimensions?
I''ve been working with Gruff to do all my apps graphing and such etc. I
love it but I''m just having a hard time customizing the graphs, but this
is perhaps due to my inability to comprehend the online RDocs.
What I want to do is adjust the width / heights of my graphs or at the
VERY LEAST the heights. It seems that if you scale a graph anywhere
below 400-450px it is pretty
