similar to: add_primary_key Re: #3735

Hi, We use "add_primary_key" method in the active record script to create primary key in a table. But this method does not allow us to create our own primary key constraint name. Is there a way where we can give our own constraint name ? please help !! Appreciate your response. Thanks, John -- Posted via http://www.ruby-forum.com/.

Hi all, This is my first post to the forum, and I''ll point out right away that I''m a noob to everything, Ruby, Rails, MySQL, etc., so I expect that I''m wrong here, but is the ''year'' datatype missing from ActiveRecord in 2.0.2? According to my MySQL 5.0 reference manual, ''year'' is a datatype, but when I try to run a migration that has

Is anyone using migrations with a SQL Server database who might be able to lend me a hand? I''ve used migrations with MySql in the past and haven''t run into any issues so forgive When I run rake migrate nothing is actually getting updated in my database. I created a migration using ./script/generate migration AddFooTable and updated the migration to look as follows: class

How does one do a SELECT MAX query in rails? I''ve searched and searched and tried lots of things with no luck. I want to implement "SELECT MAX(column_name) from table_name and have it return the maximum value from column_name. I just need to get that one value, not the whole object... Thanks for any ideas...

Hi, after some experience with Rails on MySQL databases I gave it a try on one of our larger Oracle database. I was facing a problem when Rails tried to detect the columns for a model/table. The appropriate statement ran about 1 min which led to a timeout. Our Oracle guru told me to analyze the SYSTEM schema. After that hadn''t helped, he said the only remaining chance is to use a

I''m just looking into how to connect to Oracle using Rails. I''ve got everything connecting and working as it should. I have a Users table in Oracle: create_table "users", :force => true do |t| t.column "username", :string t.column "created_on", :datetime t.column "email", :string t.column "note", :text

Hi all, when I execute the command "rake db:schema:dump" i get this error in the db/schema.rb file. ____________________________________________________ # Could not dump table "region" because of following ActiveRecord::StatementInvalid # OCIError: ORA-00918: column ambiguously defined: SELECT lower(i.index_name) as index_name, i.uniqueness, lowe r(c.column_name) as

development.log contains quite a few SELECTS on system tables like COLUMNS. Wouldn''t it be more efficient to cache this info? I''m also wondering about strings like "[4;35;1m". What''s their purpose and is it possible to get rid of them? They look like screen coordinates and makes no sense in a text file. Christer Processing ReportController#create (for

While working on win32-service-0.3.0 I got hung up trying to resolve that "RPC server is unavailable" error message that was popping up on some systems. I couldn''t duplicate this on my XP Pro box, but it does show up on my Win2k box. Quick review - this is the test case from tc_service.rb def test_services assert_nothing_raised{ Service.services{ } }

Hi, after changing a primary key column name, the auto-increment information (MySQL) and sequence (Oracle) are lost. What is the correct way to rename primary keys?

Hi... I want to know the equivalent instructions to insert, update, search and delete a registry. I know Rails can do it easily Thanks to ActiveRecord, but here''s the catch: I''m using PostgreSQL. As I''m using SQL to do the migration (Including the foreign keys), I need to know if I can use SQL queries to do those actions. Is there an example out there? I uncommented

I am unable to get ActiveRecord session support to work under 2.x against a SQL Server database. I''m starting to wonder if anyone is running 2.x against SQL Server? Is anyone running under the following configuration: Rails 2.x SQL Server 2000 DB (using AR adapter in ODBC mode) AR store for ActionController session store. I''d like to chat with you if you are. Thanks, Wes --

Hey guys, I''ve been trying out ferret 0.9.3 on my powerbook this weekend and I''ve been triggering ''bus errors'' when using the Query API. If I programmatically build up strings, it works just fine. There''s some more information available in the trac ticket http://ferret.davebalmain.com/trac/ticket/62 Is anyone successfully using the Query API on

I still want to get this into Rails for all connection adaptors, but for now I''ve hacked my own addition on for just PostgreSQL. The following code extends every Column object returned by MyModel.columns to support a new #required? method, which indicates if the column may or may not be null. The following is a huge hack - suggestions on a cleaner way to add this functionality

Greetings, I''m trying to put a Rails face on a Legacy Oracle 10 table. I am currently setting the table_name and primary_key, and I get the list and show to work fine. However, when I hit edit I just get the Editing <table name>, Edit button, Show, and Back. None of the fields are rendered. Why would I be able to show these fields in the show and list, but not edit them in the

http://dev.rubyonrails.org/ticket/1117 I''ve attached a patch to ticket 1117 which fixes it so that booleans are escaped as booleans, not integers. Specifically, this situation will now work find_all(["send_date=? and sent=?", Date.today, false]) Which matches peoples expectations, but it causes some problems with the postgresql unit tests. Specifically, the use of

Hi, While I was hacking ovirt-server, I have found that it's currently restricted to Postgres DB. Even if I like postgres for serious work on a server, I really prefer to hack/dev locally on a Sqlite or MySQL DB. I have googled on rails in order to find a good answer for the "foreign key problem" which forces OVirt to stay on pg. I have found a plugin on this particular
