Bad file descriptor - connect(2)
Hi All,
I am a newbie in Ruby-Rails. Actually we are using postgre SQL and Ruby
application to access the DB. I have made the controller and the model
classes. My database.yml contains:
development:
adapter: postgresql
database: test
username: poc
password: poc
host: localhost:5000
test:
adapter: postgresql
database: test
username: poc
password: poc

PostgreSQL, postgres gem, rails2.pdf, http://ruby.scripting.ca/postgres/ confusion...
Hello people...
In the rails2.pdf Dave T says:
Rails works with the DB2, MySQL, Oracle, Postgres,...
The database drivers are all written in C and are primarily distributed in
source form.
Then he lists this site:

Then he says,
There is a pure-Ruby version of the Postgres adapter available. Download

Freezing Architecture-Dependent Gems such as Rmagick, Ferret, Unicode
A lot has been made recently about the need to freeze your gems for
production deployment on a shared server so your application can depend on
it''s own gem version instead of being subjected to whatever gem is installed
on the server, but does this rule of thumb come with an exception?
Architecture dependent gems such as RMagick, Ferret and Unicode have
dependencies that cannot be

File.size() on Uploaded Images Fail
I am checking the file size of an uploaded file and storing it in a filesize
column. It will work just fine when the user uploads any files other than
images (jpg,png,gif).
Word, Excel, Powerpoint, .zip and more all work fine.
This is my model asset.rb that handles the file upload.
def newfile=(newfile_field)
self.filename = base_part_of(newfile_field.original_filename)

testing file uploads
Hi all,
I was wondering about the class used when rails receives file uploads.
Sometimes it appears to be a File, and other times it is a StringIO.
Also it has methods such as original_filename that don''t appear to
belong to either of these classes. I ask because I''m trying to work out
how to test my fil upload related models and controllers.
Is there some standardised way of

file_column do download from URL
Is there a simple way of forcing file_column to download file from given

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?

Image upload problem.
I''ve seen posts of a few people who have this problem, but not a single
response about solving it.
I can''t upload .png files, but .jpg and .gif work fine. When I upload just a
.png, my action gets a StringIO object which breaks when I try to copy the
upload to an absolute location. However, using multiple-field upload, as
long as one of the to-upload files is *not* a .png, all

SVG and tooltips, hyperlinks
Dear all,
is there a good way to create SVG plots with R whose elements have
titles (tooltips) or act as hyperlinks?
I am using the RSvgDevice package, which works great - but it doesn't
seem to support the notion that plot objects have titles or are act as
hyperlinks, so I am helping myself by giving the objects funny unique
colors and then postprocessing the .svg file.

Input/output error on linux
Hi,
I''m trying to use mongrel 0.3.13 with Rail 1.0
Believe it or not, on OS/X it works well for weeks at a time. On
linux I''m getting Input/output errors after anything from a few hours
to days, never more than a week. Once they start they don''t stop.
The only pattern I''ve seen is that it always (seems) to happen while
rendering an rhtml file.

File Upload problem when file is small, under 19k(read method returns nothing)
Hi
I hope someone can shed some light on this have searched a lot but found
nothing definite. This happens on Ubuntu and Fedora 2.
I am having a problem with uploading small files (images gif or jpeg
under 19k).
According to ruby documentation these are stored temporarily as StringIO
objects rather than temporary files (as is done with the larger file
uploads).
The problem is that when it

Testing custom mongrel handlers?
Hey Folks-
I''m trying to setup a new test/spec harness for testing Merb. I was
wondering if there is a way to mock the Mongrel request, response
objects easily to test my handler without actually running a server?
I can easily do the env hash but I''m not entirely sure what needs to
go in the request StringIO object that gets passed into my mongrel
