similar to: rspec & table type MyISAM

Hi, I have been using myisam tables in mysql with rails because my client will soon want fulltext searchable content, however when I migrated my development db from schema.rb all of the tables generated were innodb. I understand that I can override this, but also like the transactions and foreign keys of innodb. So 2 questions really: 1. are transactions in activerecord dependent on innodb or do

I tried adding a FULLTEXT search index to a table of mine in MySQL, only to discover that the InnoDB table format doesn''t seem to support this feature. Switching to the MyISAM table type seemed to work, but I seem to have some recollection that ActiveRecord transactions aren''t fully atomic on MyISAM tables. Is this true or am I just remembering wrong? If so, does anyone have

I''ve been creating my tables using the command line approach Dave advocates in AWD. I just noticed that they''re being created as MyISAM-type tables. I remember reading (but not where) that I should be creating these as InnoDB-type tables. So, two questions... 1) Is the table type important? (a "why" component to the answer would be nice too ;-) ) 2) If so, is

Hi, I am a RoR newbie and I''ve been experimenting with different databases (mySQL, PostgreSQL, etc.) and different table types (MyISAM vs. InnoDB). Is there a preferred database/table type for RoR development. I like how MySQL''s InnoDB tables enforce referential integrity, but these tables require a lot more storage space then MyISAM tables. For everyone with a lot of RoR

I''ve been looking through some references but can''t seem to find the right syntax and commands. I basically just want to have a migration to convert my db and all my tables to InnoDB.

Hi all, I am starting out learning Ruby on Rails (coming from a PHP background) and I have a question about proper database design. 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`

Dear R Developers, In the same way that MySQL/MariaDB's Engine InnoDB or MyISAM/Aria have the innodb_buffer_pool_size or the key_buffer_size for setting the maximum amount of RAM which can be used by a Server Instance: ?Would it be possible to create an R Configuration Variable which fixes the maximum amount of RAM memory to be used as Commit / Dynamic Memory Allocation? Thank you. Juan

Can anyone point me to the proper syntax to build a FULLTEXT MySQL index via migrations? I''m really liking these things, and don''t want to step back into the world of manual intervention.

I''m currently using Perl, Class::DBI, Template Toolkit on top of Mysql and I''m about to try my hand at a first Rails app. The power of Rails and Ruby has me very intrigued... The O-R mapping in Class::DBI seems to be covered by AR, so I''m hoping it is a workable proposition. I plan to build a simple test case to get up to speed before converting a large production

Hi Guys, I just wanted to take a moment to give some positive feedback regarding my experiences with Xapian recently. I've been doing a fair amount of research into search engines recently, as we have some fairly specific requirements with what we're attempting to do with them. Long story short, after a few weeks of playing around with just about everything under the sun (or at least,

Hi all, Ive been getting this error on one particular query repeatedly for the past few days. ActiveRecord::StatementInvalid: Mysql::Error: Lock wait timeout exceeded; try restarting transaction: UPDATE `posts` SET `updated_at` = ''2010-03-17 05:35:00'', `view_count` = 54 WHERE `id` = 158 Googling around, I found that this is basically because the transaction times out after

so for relational associations, do i need to actually be using an rdbms like innodb or bdb? or can i get away with myisam and assume that telling ruby how i want the tables related will be good enough (ie, has_one, has many, etc)?

I have converted my engine from myISAM to InnoDB, the matter now in Test Unit, the table cant do any changes for CRUD. Any advice? But if I convert it back, the CRUD can run very smooth and data value in attributes changed.

Hello, This forum has been very helpful to me in the past, and I've run out of ideas on how to solve my problem. I had been using R and MySQL (and Perl) together for quite some time successfully on my Windows XP machine. However, I recently had some problems with MySQL (the ibdata file had become 35GB on my hard drive, turns out it's a known bug with InnoDB), and ultimately the way I

Hi All, In my companies environment, we have multiple sites in multiple geographic locations, sometimes with high latency between the sites. I''m trying to come up with a solution that could provide puppet infrastructure to all sites nodes. ----a few assumptions--- - puppet manifest / configuration is fetched from a centralized version control system. - store db is needed (ssh keys,

I just installed acts_as_authenticated into an app and one of its unit tests is failing. The cause is that another unit test''s changes to the AAA fixtures aren''t being rolled back. I''m confused, since I have transactional fixtures turned on and MySQL InnoDB engine being used. Details: - MySQL 5.0.24. InnoDB is the default engine, all tables in the test db are using the
