I have checked for method/association name clashes and can't see any.
Any tips on how I might debug this further would be very much
appreciated - I am completely stuck!
To recap, I am getting the error "undefined method `each' for
true:TrueClass" when an Active Record method (in active_record/base.rb
- see below) is being executed. So I assume 'attribute_names' is being
set to true for some reason.
# Returns a copy of the attributes hash where all the values
have been safely quoted for use in
# an SQL statement.
def attributes_with_quotes(include_primary_key = true,
include_readonly_attributes = true, attribute_names =
@attributes.keys)
quoted = {}
connection = self.class.connection
attribute_names.each do |name|
if (column = column_for_attribute(name)) &&
(include_primary_key || !column.primary)
value = read_attribute(name)
# We need explicit to_yaml because quote() does not
properly convert Time/Date fields to YAML.
if value && self.class.serialized_attributes.has_key?
(name) && (value.acts_like?(:date) || value.acts_like?(:time))
value = value.to_yaml
end
quoted[name] = connection.quote(value, column)
end
end
include_readonly_attributes ? quoted :
remove_readonly_attributes(quoted)
end
