similar to: ActiveRecord::SubclassNotFound: The single-table inheritance mechanism failed to locate the subclass: 'Transactions::DummyDdnlTransaction'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Pleas

FIXED: Transaction is a reserved word, and it cannot be used even though I put it into its own module. So my guess is Transactions::Transaction still somehow got resolved to the Rails internal Transaction class. Renamed the Transaction (and its subclasses) to Transact and it works fine now.

So by default to get STI, I would have something like: create_table :items do |t| t.column "type", :string t.column "title", :string end But if I want to store those type values in a separate table, such that I have ... create_table :items do |t| t.column "item_type_id", :string t.column "title", :string

Hi, I''m having fun playing around with Camping...I am slowly working on extending tepee to a personal e-notebook sort of tool (never lose my papers/revisions....hehe). I''ve given tepee an oswd css design, and am currently adding a admin page that I want to show the ruby version, sqlite version and db size and db stats information. I tried running: @db_stats =

Hey, I have been looking at ActiveRecord''s serialization code, and noticed that ActiveRecord::XmlSerializer#serializable_attributes purposely excludes the STI inheritance column per ``options[:except] = Array(options[:except]) | Array(@record.class.inheritance_column).'''' Is there a particular reason for this? Would anyone be opposed to my writing a patch to have this

I have been struggling for quite sometime with this. Is there any way to configure the Model to store user defined value in the inheritance_column instead of the default value (which is class_name) The problem I have is like this: I have a User model and there are different models which inherit from this like Admin, Premium, Professional, etc. Each of these inherited models are identified by a

Hi! I have a legacy table that has a column named "type" and need to remove this automatic subclassing by ActiveRecord. The api pages are vague about this, and I tried self.inheritance_column = "xtype" which seemed to get me half-way. In the validate_on_create method, the value of self.type was my model Class name. How would you disable this feature? -- Posted via

Hi, I''ve dug into some previous discussion on this list about having multiple clients running on a single Rails site. I can see how to work this out with a single project type. For example, my tenants all have their own CMS in a single Rails environment. What if 3 of my clients have a CMS site, 5 have an e-book site and 2 a dating site. Is there a way to house these websites within a

I''ve made a inheritance rework some weeks ago that would possible fix it since it only loads the inheritance support in the class that''ll use it. In STI case, it would load only if the class that descends directly from AR has been inherited and the column specified in the inheritance_column is available. People here told me to wait until next release so we can dig into this, but

I updated some of my gems, and I think it may be the reason I am getting the following error when the agents try to retrieve a catalog. err: Could not retrieve catalog from remote server: Error 400 on SERVER: The single-table inheritance mechanism failed to locate the subclass: ''Host::Managed''.

Hi Chandler, That's embarrassing how weird this part of clang is. I have a provisional patch which fixes the problem but underlines clang's problems.

Hi, Try powering down, then as soon as you reconnect press the # key. This should invoke the factory reset, followed by entering 1234556789*0# when requested, which will wipe the phone. Make sure that you have the appropriate image available as the next reboot will look for the OS79XX.TXT file, then image, which if incorrect could lead to an expensive paperweight! I would recommend
