generate_message(attribute, type = :invalid, options = {}) Instance Public methods Translates an error message in its default scope (activemodel.errors.messages). Error messages are first looked up in models.MODEL.attributes.ATTRIBUTE.MESSAGE, if it's not there, it's looked up in models.MODEL.MESSAGE and if that is not there also, it returns the translation of the default message (e.g. activemodel.errors.messages.MESSAGE). The translated model name, translated attribute name and th

content_tag_for(tag_name, single_or_multiple_records, prefix = nil, options = nil, &block) Instance Public methods #content_tag_for creates an HTML element with id and class parameters that relate to the specified Active Record object.

e.peek_values â array Instance Public methods Returns the next object as an array, similar to #next_values, but doesn't move the internal position forward. If the position is already at the end, StopIteration is raised. Example o = Object.new def o.each yield yield 1 yield 1, 2 end e = o.to_enum p e.peek_values #=> [] e.next p e.peek_values #=> [1] p e.peek_values #=> [1] e.next p e.peek_values #=> [1, 2] e.next p e.peek_values # raises StopIter

==(p1) Instance Public methods Tests for value equality; returns true if the values are equal. The == and === operators and the eql? method have the same implementation for BigDecimal. Values may be coerced to perform the comparison: ::new('1.0') == 1.0 -> true
