Hi, We have experienced some problems with ActiveRecord::Base class of Ruby-Rails. We are building a web-application based on the Ruby-rails framework and the web-application needs to access to difference databases, so we do not pre-define our database accesses in the database.yml file. In fact, we are using the ActiveRecord::Base.establish_connection() to connect to our database, the function

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

Hi, I really need help to understand what is happening while Rails connect to a database, (we area actually using postgresql, so my example will be with postgresql) What I understand is Rails is able to connect to different DB. Actually, this is what we want, and we have made some tests, everything is juste fine. However, all these tests lead us to some important questions that we did find the

This seems pretty brain dead: add_column :types, :notify_on_create, :boolean, {:default=>true, :null=>false} $ rake migrate Error: ERROR: column "notify_on_create" contains null values : ALTER TABLE types ALTER notify_on_create SET NOT NULL Why doesn''t Rails set the new column to true, as it''s supposed to default to? I tried :default=>1 as well (same

I''m working with a legacy postgresql database where the names of tables, columns, etc., do not usually follow Rails conventions. I''ve been able to work around it for the most part, but I ran into this: I have the following test: require File.dirname(__FILE__) + ''/../test_helper'' class SponsorTest < Test::Unit::TestCase self.use_transactional_fixtures =

I need to bootstrap my database when creating schema. My model class and migration class are the same. When I trying: ClassName.create :foo => ''bar'' in migration I got: undefined method `create'' for #<ActiveRecord::ConnectionAdapters::PostgreSQLAdapter:0xb75a357c> How to avoid this? I think the same class names causes problem, but I can''t change

Dear all, I am trying to use the Matrix package to do some calculations on rather large and sparse matrices. An example of such a matrix is given below. mig<-0.2 side<-10 np<-side^2 mig.mat<-matrix(0,np,np) diag(mig.mat[1:(np-side),(side+1):np])<-mig/4 diag(mig.mat[(side+1):np,1:(np-side)])<-mig/4 diag(mig.mat[-np,-1])<-mig/4

The src_owner field in struct migrate_vma is being used for two purposes, it acts as a selection filter for which types of pages are to be migrated and it identifies device private pages owned by the caller. Split this into separate parameters so the src_owner field can be used just to identify device private pages owned by the caller of migrate_vma_setup(). Rename the src_owner field to

Add a new opaque owner field to struct dev_pagemap, which will allow the hmm and migrate_vma code to identify who owns ZONE_DEVICE memory, and refuse to work on mappings not owned by the calling entity.

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
