As I wasn’t able to google a solution I came up with the following (not quite elaborated) code:

class OwnLogger < Logger

    include Severity
    SEV_LABEL = %w(DEBUG INFO WARN ERROR FATAL ANY)

    def add(severity, message = nil, progname = nil, &block)
      time = Time.now
      if ENV['LOG_FROM_INFO_TO_STDOUT']
        if severity >= INFO
          msg = "#{$$}:#{SEV_LABEL[severity]}:" + time.strftime("%Y-%m-%dT%H:%M:%S.") << "%06d " % time.usec + ":"
          if message.nil?
            if block_given?
              message = yield
            else
              message = progname
              progname = @progname

            end
            msg += message.to_s
            puts msg
          end
        end
        super
      end

    end

So if you put the following lines in your /config/application.rb you’ll get what I got

config.logger = OwnLogger.new(File.dirname(__FILE__) + "/../log/#{ENV['PROCNAME']}#{Rails.env}.log")

AND (most important) you’ll still have the “normal” logfile containing all messages

I found:
http://stackoverflow.com/questions/246983/informix-how-to-get-an-id-of-the-last-inserted-record

[...]The value of the last SERIAL insert is stored in the SQLCA record, as the second entry in the sqlerrd array. Brian’s answer is correct for ESQL/C, but you haven’t mentioned what language you’re using.
If you’re writing a stored procedure, the value can be found thus:
LET new_id = DBINFO(‚sqlca.sqlerrd1‘);
It can also be found in $sth->{ix_sqlerrd}[1] if using DBI
There are variants for other languages/interfaces, but I’m sure you’ll get the idea.
[...]

I got the idea and have created the following procedure

CREATE PROCEDURE lastid ()
RETURNING integer;
DEFINE lastid integer;
LET lastid = DBINFO(‘sqlca.sqlerrd1′);
RETURN lastid;
END PROCEDURE

So to get the latest column you just use

select lastid() from table(set{1})

btw.: If you want to make use of this in Rails, I’d some success with:

class InformixConnect < ActiveRecord::Base
self.abstract_class = true
establish_connection :development_informix

def save
super
self.id = self.connection.select_value(“select lastid() from table(set{1})”)
end

end

so a model like

class Customer < InformixConnect
        
end

would be able to connect to Informix and to get correct values from the DB without the
usage of sequences!

ERROR
Unfortunately the stuff above (overwriting the save method) does not work for some reasons.

I have patched

class InformixAdapter < AbstractAdapter

def prefetch_primary_key?(table_name = nil)
false
end
….

def insert(sql, name= nil, pk= nil, id_value= nil, sequence_name = nil)
execute(sql)
select_value(“select lastid() from table(set{1})”)
end
…..

This works!

Most of my application icons were broken, i.e. only visible in a very low resolution.

After googling a bit I found the following discussion:
http://discussions.apple.com/thread.jspa?threadID=2142401

mdi’s suggestion did the trick for me: http://discussions.apple.com/message.jspa?messageID=10296267#10296267

What I did:

• open Terminal.app (If you never did… : Try „spotlight-search“ –> Terminal)
• enter cd /private/var/folders
• enter sudo find . -name “com.apple.QuickLook.thumbnailcache”|xargs sudo rm -rf

                (you will have to enter your password)

• Restart Finder.app using „Apple-Menu–> „quit immediately (It’s „Sofort Beenden“ in German. Dunno the english term) or press
• command+option+escape“. Chose „Finder restart“.
• Be happy

OK, to be honest I had to restart to be really happy

records = Model.find(:first).

Guess why:

I made use of a legacy table that contained the attribute „type“. I just had to add a

self.inheritance_column=’itype’

into my model and now everything’s OK.

Rails: Do you consider this as friendly error messages?
