I''m studying the Agile Development with Rails book. In the chapter that first sets up the depot application (page 68), there is this bit of code from a view: <% for product in @products %> <tr> <% for column in Product.content_columns %> <td><%=h product.send(column.name) %></td> <% end %> etc...

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

Hello! I''ve modified ActiveRecord a bit to support enum columns. This is tested only with MySQL, and maybe needs some changes for other adapters (if they use another syntax or quoting style). I believe this patch should be tested well, so I haven''t (yet) tried to post it to the official Trac. It is also not solid-as-a-rock when it comes to quoting ENUM values. After

I''m getting the following bug when I try to run rake db:migrate in Rails 3 beta 4: $ rake db:migrate --trace (in C:/Users/Adam/Documents/Aptana Workspace/QuestionBank) default formats are encoded in ISO-8859-1 ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate == CreateUsers: migrating

Hi all, I am in the process of adding Migration support to the Ingres ActiveRecord adapter and have run in to a problem. During the call to create_table the Ingres adapter some how causes ruby to blow the stack and coredump/segv. I have tracked down the problem down to "add_column_options!" in "lib/active_record/connection_adapters/abstract/schema_statements.rb".

hi, I am experiencing a very strange problem with my Rails installation. I''m using ruby 1.8.6 on Debian Linux, with edge rails. Whenever I try to start mongrel, I get an exception about "can''t modify frozen string". I get a similar exception when I try to do "rake db:migrate". In this case, the exception seems to pop up *after* the migrations do succesfully

Hi, I have a database table and associated ActiveRecord model. I was trying to store (temporarily) an array in one of the attribute elements - not to save it, but just so that I can keep some form data in a sensible place. A stripped down version of the problem I''m having is: p = Property.new(:bedroom_count => ["2","3"]) puts p.inspect # ==> will correctly show

Often I need to do a one-off validation before Rails has had a chance to convert. For example, a date. Is there a general mechanism to cause validations to run on the raw input or do I have to resort to: private def validate unless attributes_before_type_cast[''date_of_loss''] =~ /^(\d+(-|\/)){2}\d{4}/ errors.add(''date_of_loss'', ''use the

Hi I have the following values pActualCost = 33.00 pPaymentCost = 29.99 So this calculation should leave me with 0.01 pPaymentDifference = pActualCost - pPaymentCost however when doing this in rails, it returns 0.00999999999999801 has anyone got any suggestions to whats going wrong and how I can correct this Thanks Scott -- Posted via http://www.ruby-forum.com/.

Mmmh, seems as if I really should change my options as I seem to keep sending off empty bug-reports ;-/ Sorry guys.

I''m working on an existing global database running on MS SQL Server.

Hi all! I have come into a strange issue in Rails that I am hoping someone can shed some light. To make a very long story short, I have been researching how to override ActiveRecord::Base#read_attribute and write_attribute to perform security checks at the model level (influenced by the ModelSecurity generator). Shortly after implementing some code to check this behavior, I began to
