Let me give you a quick example of what I want to do: Database: CREATE TABLE `users` ( `id` int(11) NOT NULL auto_increment, `login` varchar(40) default NULL, `email` varchar(100) default NULL, `crypted_password` varchar(40) default NULL, `salt`

Hello, I am trying to put my rails app on a host .So I presume the method to do this is to first do rake db_schema_dump and then copy it to the host and do rake db_schema_import. I use mySQL Ver 14.7 Distrib 4.1.14, for pc-linux-gnu (i686) using readline 4.3 ** Invoke db_schema_import (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db_schema_import rake

Hi list! I'd like to save all information about calls (CDR) in a MySQL-Database. I created the DB and a user for Asterisk on a separate server, then I configured my cdr_mysql.conf so: [global] hostname=192.168.10.3 dbname=asterisk table=cdr password=MYSECRET user=asterisk port=3306 and my cdr.conf so: [general] enable=yes unanswered = yes safeshutdown=yes [mysql] usegmtime=no

Hi everybody I am totally new to rails and I am trying to start a tiny project to get familiar with rails. But I already got my first problem and I would be happy if somebody could point me in the best and cleanest direction. I am trying to develop a small gallery app. Since I would like to add more features in future I am trying to design a clean OO architecture of my models: The base object

Ok, to keep things short. Im wondering if I need a secondary relationship table to handle my many-to-one relationships. Here is an example of what I''ve written down. For instance say I want to find all of the people in a given location. class Location < AR:Base has_many :people end class Person < AR:Base belongs_to :location end My SQL tables look like: CREATE TABLE

Hello, I''m a beginner, so any hints are appreciated; I''m still trying to find my way around Rails code. For a bug I''ve found I need to create a table called "values" so I added this: create_table :values do |t| t.integer :value end among the other table creations in activerecord/test/cases/migration_test.rb. Is that ok? But then, when I run the tests

Hi all, I hope someone can help with what is probably a simple newb installation mistake on my part. I''m having a couple of problems with the salted hash login generator.

I'm having a few issues with the MySQL realtime configuration in CVS-HEAD. I tested it initially with realtime extensions (realtime_ext => mysql,asterisk,extensions) and a realtime switch in extensions.conf and that works fine, So I though I'd go back and test a static configuration mapping.
