Hi: I am new to the ruby and rails. What I am tried to do is to create a scaffold based on an existing table in a MS SQL Server database. Before I used the set_primary_key method, edit and show does not work in the generated code. Rails displayed the list of the records ok, but can not determine the id for each record. Create a new record does work properly, however. After I used the

We are trying to use set_primary_key to cause an existing rails db to use a different primary key. This works find for accessing existing data, but gives an error when we try to add a new record, as it seems to still be accessing the record by the default id field at that point. Are there other changes we need to make to get an alternate primary key working? Thanks, Ken

I''m using a legacy table, where the unique id is not ''id'' I have a Model class like the following: class Article < ActiveRecord::Base set_primary_key "ARTICLE_ID" end however, using a link_to like the following (modified scaffolding), the link has no id value: <% for article in @articles %> <tr> <% for column in

I found what was wrong with sqlserver adapter. I can rename "id" to other name and it works. Only scaffold does not work correctly. It ignores my set_primary_key command and is looking for "id" name. -- JZ

Hi all. I am trying to populate a dropdown based on two values. def self.clientref( reference ) @bugclientrefs = self.find_all(["bug_id = ?", reference]).collect {|b| [ b.client_id.strip << " - " << b.client_ref.strip ]} end This works fine. However this returns the reference to the client. I want the full name using this function. class Bugclient <

This is my first rails app with a legacy database and I''m having a terrible time getting the models set up correctly. I have an order table that has a primary field named order_number. I have a name table with a primary of item_number. These two tables are liked by the item_number and the order_number, but not as you might think. If the order_number is 2500, then each entry in

I''ve got a fairly simple system with a table for my Users that includes a CountryId field which looks up to the CountryId field of my Country table. What I would like to happen is for my Rails application, which contains models for both User and Country, to be able to draw the dropdown list of available countries on the edit page, like it does in all the tutorials. My model classes look

probablly a newbie question: Rails does not support a table with multiple keys ??? it seems that the ActiveRecord set_primary_key method can only set the column name... (hope i''m wrong there) example: table A - P.K id, string name table B - P.K id, string name table C - P.K a_id and b_id, both are also foreign keys.

I''ve got a problem with some tables that don''t follow any RAILS standards. how do I define the join in the model when all three tables have wacky names? class Machine < ActiveRecord::Base set_table_name "tbl_CodeMgmt_Host" set_primary_key "Id" end class Pool < ActiveRecord::Base set_table_name "tbl_CodeMgmt_Pool" set_primary_key

I have some legacy tables that I used set_table_name on, I''m attempting to write a method that will get key value from a sequence table and then update it and return a value. I''m hoping to put this in the base ActiveRecord method so I would like to reference the table name with self.table_name or something... class Contacts < ActiveRecord::Base set_table_name

Dear all, Please help me in this regards, I am using models to access LegacySchemas using set_table_name and set_primary_key... [code for model] class CdDetails < ActiveRecord::Base def self.find_data set_table_name ''cd_details'' set_primary_key ''cd_label'' find (:first, :select => "cd_label") end

I''m experimenting with Rails on the Recipes example first before I dive into applying it to my intended application. I''m exploring which will be more work: to rename all the primary id''s in the legacy database, or to work around the fact that the primary id''s are not called ''id'' within RoR instead. I''ve been successful in using a

I''m playing out with writing an online store. So far it has accounts, addressbooks, and orders, and those 3 are tied together with an customer ID. I also have orderDetails, which are associated to the order via an order number. See models below... When I do the following I can access the orderDetails information just fine: @order = Order.find(params[:id]) # i pass it a customer

I just switched from using the standard "id" column into using my own primary key and generating my own unique id for each record. But, this breaks acts_as_tree. Because my new primary key is not an integer, it breaks the SQL query as follows: StatementInvalid in PagesController#create --------------------------------------------------------------------------------------

I am applying Rails to an existing schema and not sure how much the existing developers will let me go in and rename things. So I need to discover the limits of what I can change with Rails. I''ve found set_table_name and set_primary_key, which have been very useful. If I have a "foo has_one :bar" relationship, but then in the bar table my column is named "fooid"
