primary_key() click to toggle source

Defines the primary key field – can be overridden in subclasses. Overwriting will negate any effect of the primary_key_prefix_type setting, though.

# File lib/active_entity/attribute_methods/primary_key.rb, line 62
def primary_key
  unless defined? @primary_key
    @primary_key =
      if has_attribute?("id")
        "id"
      else
        nil
      end
  end

  @primary_key
end
primary_key=(value) click to toggle source

Sets the name of the primary key column.

class Project < ActiveEntity::Base
  self.primary_key = 'sysid'
end

You can also define the primary_key method yourself:

class Project < ActiveEntity::Base
  def self.primary_key
    'foo_' + super
  end
end

Project.primary_key # => "foo_id"
# File lib/active_entity/attribute_methods/primary_key.rb, line 90
def primary_key=(value)
  @primary_key = value && -value.to_s
end
