  raise "Multiple matching foreign_keys. Only unique foreign keys allowed [#{field}]" if matching_fields.count > 1

#belongs_to_field?(field) ⇒ Boolean

Returns:

  • (Boolean)

#many_to_many_associated_tables ⇒ Object

OData does not allow creating an entry for a table that is used in a many to many joining table. You must associate tables together. If a table uses this field, it indicates its a joining many to many table. An array of the 2 associated tables, eg [Table1, Table2]

  @many_to_many_associated_tables = value
end

#many_to_many_binding_name ⇒ Object

Binding name is found in the metadata xml file. It will look something like (system users - opportunities): <EntitySet Name=“systemusers” EntityType=“Microsoft.Dynamics.CRM.systemuser”>

<NavigationPropertyBinding Path="new_systemuser_opportunity" Target="opportunities"/>

Its different for both entities, so this is a hash of tablename to binding name

  @many_to_many_binding_name = value
end

#many_to_many_use_old_api ⇒ Object

For some associations the new api does not work, notably the systemuser. But the old api does work. Hopefully in future releases Microsoft will fix the new apis.

end

#odata_field(field, options) ⇒ Object

In some cases the odata field name is different than the database field name. This method is used for this mapping

# File 'lib/active_record_extension.rb', line 127

def odata_field(field, options)
  @odata_property_key ||= {}
  @odata_property_key[field] = options[:crm_key]
end

#odata_field_value(crm_key) ⇒ Object

# File 'lib/active_record_extension.rb', line 132

def odata_field_value(crm_key)
  @odata_property_key ||= {}
  @odata_property_key[crm_key]
end

#odata_table_reference ⇒ Object

If odata refers to table differently than table name when using associations, you can use this method
