`assert_valid_fields': +options[:field]+ entry :<child_only_property> does not map to a property in <rootclass> (ArgumentError)

Reported by Andrea Dallera | September 29th, 2009 @ 08:56 AM | in 1.0.0

The following code:

require 'rubygems'
require 'dm-core'

include DataMapper::Types

class Root
  include DataMapper::Resource

  property :id, Serial
  property :name, String
  property :type, Discriminator

class Branch < Root
  property :value, Integer

DataMapper.setup(:default, {:adapter => 'sqlite3', :database => 'test.db'})

branch_one = Branch.new
branch_one.name = "branch one"
branch_one.value = 42


entities = Root.all

p entities[0].value

raises an ArgumentError, coming from an assert in Query. The cause is that entities[0] is recognized as a Root while it is a Branch instead in the Query constructor (line 590 in query.rb), which determines @property to be Root.properties and not Branch.properties and then causes the assert fail in assert_valid_fields

    I ran this against dm-core (v 10.2) and it works fine so I think you can close this.

    • Milestone set to 1.0.0
    • State changed from “new” to “resolved”
    • Assigned user set to “Dan Kubb (dkubb)”

    I can also confirm this works with DM 1.0.0 rc3.

    I believe this was resolved in some changes I made before 0.10.2 in how Query tests the properties added to the query fields.
