Hi all, I'm implementing an activerecord connector on top of a database driver I wrote (in pure ruby). The platform of reference is a Mac OSX 10.5 box with the shipped ruby interpreter version 1.8.6 and activerecord 2.3.2. Table creation and select queries work; I though have some problems when I try to perform insertion. As an example I created a table called 'albums': ActiveRecord::Schema.define do create_table :albums do |table| table.column :title, :string table.column :performer, :string end end class Album < ActiveRecord::Base end Manual insertion works: sql>insert into albums (title, performer) values ('a', 'b'); +----+--------+--------------+ | id | title | performer | +==+====+=======+ | 1 | a | b | +----+-------+---------------+ Selection seems to be working: puts Album.find(:first)['title'] returns: "a" When I try to call the create method though I get an AttributeError: album = Album.create(:title => 'Black and Blue', :performer => 'The Rolling Stones') /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/ base.rb:2745:in `attributes=': unknown attribute: title (ActiveRecord::UnknownAttributeError) When enabling Logger I get the following: Exception occurred during reader method compilation. Maybe "performer" is not a valid Ruby identifier? compile error /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/ attribute_methods.rb:211: syntax error, unexpected tSTRING_BEG def "performer"; missing_attribute('"performer"', caller) unless @attributes.has_key?('"performer"'); @attributes['"performer"']; end ^ /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/ attribute_methods.rb:211: syntax error, unexpected kEND, expecting $end def "performer"; missing_attribute('"performer"', caller) unless @attributes.has_key?('"performer"'); @attributes['"performer"']; end [...] May there be any problem with the implementation of my database driver? Maybe type conversion? I googled but I was not able to find any hint to solve this or at least things I should check. Kind regards.
