script/runner.

wrote:

‘Usuario.usuario_del_dia’

The console says me taht I have new mail in /var/mail/jose. the mail say

At the risk of sounding completely stupid, where is your ruby
interpreter ?

Hi,

Ruby isn’t in /usr/local/bin/ruby. Run `which ruby’ to see where it is.

You shouldn’t need to have that path to ruby though before calling
script/runner, because it looks like it already has a shebang line.

Hi, ruby is in /usr/bin/ruby :frowning:

Now this is my line in crontab:

*/1 * * * * /usr/bin/ruby /Users/jose/mimandote.com/script/runner
‘Usuario.usuario_del_dia’

The problem is that since i change /usr/local/bin/ruby to /usr/bin/ruby
i don’t recive any mail. This would say thet it runs good? (i say it
because my application doesm’t work and i don’t know if is by cron or by
the programation of the model method).

I tried with this:

*/1 * * * * /Users/jose/mimandote.com/script/runner
‘Usuario.usuario_del_dia’

with the same result :frowning:

Sometimes you should test the file which is executed or not.
So I suggest you can write some code in the script to show whether it
work or not, such as
date >> ~/test.txt
After testing it ,you can permit the situation.

*/1 * * * * /Users/jose/mimandote.com/script/runner
‘Usuario.usuario_del_dia’

with the same result :frowning:

Have you tried running it directly to see if it works or not?

If it’s not giving any errors, then the script is probably running.

I try with this:

  •   *       *       *       *       echo

“hola”>>/Users/jose/prueba.txt

and it works perfectly.

This is my code…

crontab:

  •   */6       *       *       *       /opt/local/bin/ruby

/Users/jose/mimandote.com/script/runner ‘Usuario.new_usr_dia’

In my aplication

In usuario.rb -->Selects the new user of the day

def self.new_usr_dia
cambiado = false
Usuario.all(:conditions => “usuario_del_dia is NULL”, :order =>
“posicion_ranking”, :limit => 200).each do |usuario|
if cambiado == false and usuario.avatar.existe? # El usuario del
dia tiene que tener avatar
usuario.update_attribute(‘usuario_del_dia’,Time.now.to_s(:db))
cambiado = true
end
end
‘UPDATE usuarios SET usuario_del_dia = NULL’.lanza_sql if
cambiado == false
end

In avatar.rb:

The constant DIRECTORIO:

DIRECTORIO = File.join(“public”, “images”, “avatar”)
(I change it to this -->DIRECTORIO =
File.join(Rails.public_path, “images”, “avatar”). This error doesn´t
appears now:

/opt/local/lib/ruby/gems/1.8/gems/rails-2.1.2/lib/commands/runner.rb:47:
/Users/jose/mimandote.com/app/models/avatar.rb:21:in `mkdir’: No such
file or directory - public/images/avatar (Errno::ENOENT)

But the day usuary doesn’t change :frowning:

Some methods:

def initialize(usuario, imagen=nil) #It creates the directory if
doesn`t exists
@usuario = usuario
@imagen = imagen
Dir.mkdir(DIRECTORIO) unless File.directory?(DIRECTORIO)
end

def existe?
logger.debug “AVATAR.RB(existe?): directorio #{DIRECTORIO} - todo
#{File.join(DIRECTORIO, nombre_archivo)}”
File.exists?(File.join(DIRECTORIO, nombre_archivo))
end

It’s very strange for me that before I tried to run in background this
method it runs perfecly running it from application’s control zone. I
only do this from my controller

def accion_control
…
Usuario.new_usr_dia if params[:accion] == ‘new-usr-dia’
…
end

PD.
Sorry…because i know my enlish is not the best.
Thanks a lot!!
