similar to: migrations and database creation

I''ve got a bunch of table creations in the schema.rb file and all is well. However, I have to manually go and create the db first. Is there a way (something like a create_database method) to get this to work? (execute "create database ..." didn''t seem to cut it either.) _______________________ Brad Eck Sr. Software Engineer Pelco 3500 Pelco Way Clovis, CA 93612

It's generally a very good idea to examine the structure of data after you have read it in. str(data2) would have shown you that read.csv() turned your strings into factors, and that's why the == operator no longer does what you think it does. use ... data_2 <- read.csv("excel_data.csv", stringsAsFactors = FALSE) ... to turn this off. Also, the %in% operator will achieve

Hi, I have two columns that contain numbers along with letters (as shown below) and have different lengths. Each entry in the first column is likely to be found in the second column at most once. For each entry of the first column, if that entry is found in the second column, I would like to get the corresponding index. For instance, if the first entry of the first column is 5th entry in the

Combining and completing the advice from Greg and Boris the complete solution is two lines: data_2 <- read.csv("excel_data.csv", stringsAsFactors = FALSE) match_list <- match( data_2$data1, data_2$data2 ) The vector match_list will have the matching position when it exists and NA's otherwise. Its length will be the same as the length of data_2$data1. You should get

Any thoughts on how to avoid this problem? Already tried: 1. Setting the charset and collation in migration 001 - no effect: def self.up db_name = ActiveRecord::Base::connection.current_database() execute "ALTER DATABASE #{db_name} CHARACTER SET utf8 COLLATE utf8_bin" end 2. Setting the charset and collation on each table individually - no effect:

rails railscoders --database=mysql created the directory with folders except for a ''components/'' folder which Practical Rails by Alan Bradburne lists as one of the folders created. Continuing with: mysqladmin -u root create railscoders_development returns this: mysqladmin: connect to server at ''localhost'' failed error: ''Access denied for user

That doesn?t seem to work either. Where do I find logs for log rotation to see the reason it failed?

I have recently noticed that my dovecot-deliver.log is huge and wanted to start rotating it. So a couple of questions: 1. Can the dovecot-deliver.log be combined with the maillog, that gets rotated weekly? If it can be done, is it advisable? Since the inception of this particular server, the log file has been located in the /home/vmail directory. Is there a reason it shouldn?t be located in

So, the question is, why can I rotate the log manually, but cron returns a permission error? Do I need to tell cron to run it as sudo or something like that?

See my screenshot of the command here. http://a.imagehost.org/0843/mysqladmin.png When I type the following: mysqladmin create <database_name> --user=root --password=xxxxxxxx Is my command executed simply by pressing "Enter" after the command? Am I missing some syntax? If the command has been executed , what directory can I find this database? How does this relate to MySQL

I just installed CentOS 3.5. Included in the install was mysql. When trying to start it using: service mysqld start. The system responds with mysqld not recpognized as a service. When trying to use /usr/bin/mysql I receive this error: ERROR 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2). A search of the system does not reveal

Hey everybody, I've been using mysql databases more and more. I've run across a couple of instances where I've either made a mistake on the ip address of the mysql database or for whatever reason, mysql wasn't running. In those instances, I've noted that the mysql command will hang indefinitely (I've counted to 40 before killing it). The offending line is: exten =>

If you use ActiveRecord::Base.connection.create_database you''ll notice that by default the created db will use latin1 encoding. I created a plugin to handle different charset and collations (on top of helping you with other boring DB tasks). You can check out the early version of the plugin svn checkout svn://rubyforge.org/var/svn/raketasks/db_tasks (I really need to move my projects out
