Hey all. I''m trying use the form tag(s) to create a named / id''d form. I.e., I need to use JS to access the form via the DOM and submit it - support for a reusable navigation component which will persist app state on each jump. However, from reading the form_tag APIs and searching google, I don''t see where either :name or :id is an option which can be passed

I''m trying to get started with Rails, but I''m running into a few places where I''m having trouble understanding the expected workflow. I''m trying to work with migrations from the beginner; its a port of an existing application, but I''d like to let the db schema evolve as the application grows, so I''m starting from an empty (tableless) database.

Hi all, Rails 1.1.4 Rake 0.7.1 PostgreSQL 8.1.4 Windows XP Pro I checked for errata on pragmaticprogrammer.com, but didn''t see any explicit mention of this issue. I''m going over the depot example in AWDwR, 2nd ed, and I can''t get the migration to work on p. 82. Specifically, the AddTestData example (with reduced description text to save my fingers some typing):

Hey Rails People, I''m doing my first Rails app and I''m having a newbie problem with the count method.... Mysql::Error: #42S02Unknown table ''jobs_sectors'' in where clause: SELECT COUNT(*) FROM jobs WHERE (jobs_sectors.sector_id = 1 ) Extracted source (around line #4): 1: <div class="sectors"> 2: <ul> 3: <% for sector in @sectors

Has anybody heard of / written a tool/generator that quickly converts any SQL DDL into migration create_tabl tasks. i know i could just go the way of creating the tables and then do a rake db_schema_dump, but since this is something i do continuously i would like to find a quicker route. Thanks Sebastian

I started my app before migrations were a best practice and have been using SQL scripts. Now I''m looking at potentially having to move from using MySQL to postgreSQL to use a particular hosting provider. I understand migrations are the way to go to make this ''easy'' but it also looks like the use of migrations introduces extra work in other areas. I''d really

I read in various places that although migrations aren''t transactional, all you need to do is wrap you migration method in "ActiveRecord:: Base.connection.transaction do" to make the self.up or self.down transactional. In my experience (Rails + PostgreSQL), this doesn''t work very well. If my migration hits an exception, any tables that were touched remain modified.

Hi! It seems that migration doesn''t use single transcation to execute the needed migrations for the database upgrade, so if I have database at version 5, and I wrote some migrations 6..10, and error occurs while executing migration 7, the database stays in state 6? I also think that migration taks could use some more verbosity, for example if migration fails, there''s no

Hello, I recently have started to learn about R, and am interested in using it to generate data that would then get used to produce audio. Basically, I am "envisioning" using R to create the data, based on probability functions (and fractal data), which then gets output as a text data file, and then processed by CSound to produce the finished audio. My interests are based on some of

Hi all, Can I safely assume that each migration is excuted within a transaction, so that''s it''s safe to have migrations executing failing statements? Thanks, - Rowan -- Morality is usually taught by the immoral.

Hi Daniele and Arnaud, While tracking down the Cyber Power voltage scaling issue, I found the DDL repository extremely helpful. Instead of searching across all of the old mailing list posts, I was able to run 'git grep' in the Cyber Power directory, and the consistency of the data made it an easy task. I had a motherboard failure on my main computer, and I was trying to recreate the

Hi All I am trying to understand if I can use migrations to migrate data under the following conditions 1. Across 2 different databases (Oracle/DB2) with same schemas. 2. Across 2 different databases (Oracle/DB2) with different schemas. I am trying to avoid writing DBI/OCI8 scripts. Can somone please shed some light if this is even possible? thanks -daya -------------- next part

The ActiveRecord-JDBC adapter is rapidly maturing these days. I got the full set of AWDwR2 migrations to run with it against MySQL last night, and Ola Bini has gotten migrations working well against Oracle and Firebird. We also have SQL Server support running most of our test cases (under non-Windows environments too!) and have started adding support for Derby and HSQLDB (Java-based DBs). Things

Greetings railsers - I''m trying to add to a collection through HABTM, but the sql insert is trying to insert a PK rather than letting mysql produce the auto_increment''ed PK. ## @medication_dose holds a validated, saved model @medication_dose.medication_frequencies << MedicationFrequency.find (:all) The above bails with, Mysql::Error: #23000Duplicate
