Errors represents validation errors, a simple hash subclass with a few convenience methods.
Public Instance methods

count()
Return the total number of error messages.
errors.count # => 3

empty?()

# File lib/sequel/model/errors.rb 23 def empty? 24 count == 0 25 end
full_messages()
Returns an array of fully-formatted error messages.
errors.full_messages # => ['name is not valid', # 'hometown is not at least 2 letters']

errors.add(:name, Sequel.lit("Album name is not valid")) errors.full_messages # => ['Album name is not valid']
[show source]
# File lib/sequel/model/errors.rb 38 def full_messages 39 inject([]) do |m, kv| 40 att, errors = *kv 41 errors.each {|e| m << (e.is_a?(LiteralString) ? e : full_message(att, e))} 42 m 43 end 44 end
on(att)
Returns the array of errors for the given attribute, or nil if there are no errors for the attribute.
errors.on(:name) # => ['name is not valid'] errors.on(:id) # => nil
