I've got a model with its validations, and I found out that I can't update an attribute without validating the object before.
I already tried to add on => :create
syntax at the end of each validation line, but I got the same results.
My announcement model have the following validations:
validates_presence_of :title
validates_presence_of :description
validates_presence_of :announcement_type_id
validate :validates_publication_date
validate :validates_start_date
validate :validates_start_end_dates
validate :validates_category
validate :validates_province
validates_length_of :title, :in => 6..255, :on => :save
validates_length_of :subtitle, :in => 0..255, :on => :save
validates_length_of :subtitle, :in => 0..255, :on => :save
validates_length_of :place, :in => 0..50, :on => :save
validates_numericality_of :vacants, :greater_than_or_equal_to => 0, :only_integer => true
validates_numericality_of :price, :greater_than_or_equal_to => 0, :only_integer => true
My rake task does the following:
task :announcements_expiration => :environment do
announcements = Announcement.expired
announcements.each do |a|
#Gets the user that owns the announcement
user = User.find(a.user_id)
puts a.title + '...'
a.state = 'deactivated'
if a.update_attributes(:state => a.state)
puts 'state changed to deactivated'
else
a.errors.each do |e|
puts e
end
end
end
This throws all the validation exceptions for that model, in the output.
Does anybody how to update an attribute without validating the model?
You can do something like:
object.attribute = value
object.save(:validate => false)
