I have a strange behavior when validating a record in a nested form. The
association collection is empty when creating a new record and the
validation does not catch the error. But when updating the same record the
validation gets it right but continues to catch the error even after
modifying the needed attribute value to make it pass.
Here is the model:
#timesheet.rb
class Timesheet < ActiveRecord::Base
attr_accessible :status, :user_id, :start_date, :end_date,
:activities_attributes
SUBMITTED = 'Submitted'
APPROUVED = 'Approuved'
REJECTED = 'Rejected'
STATUS_VALUES = [SUBMITTED, APPROUVED, REJECTED]
belongs_to :user
has_many :activities, dependent: :destroy, inverse_of: :timesheet
has_many :time_entries, through: :activities
accepts_nested_attributes_for :activities, allow_destroy: true
validates :user_id, presence: true
validates :status, presence: true, inclusion: {in: STATUS_VALUES}
validate :maximum_worktime_per_day
after_update :check_an_activity_present
after_initialize :init_working_week
..
private
def maximum_worktime_per_day
time_entries_by_date = time_entries.group_by(&:workdate)
time_entries_by_date.each do |key, value|
errors[:base] << "Maximum daily time should not exceed 1 day" if
value.map(&:worktime).inject(:+) > 1
break
end
end
As I could see the output in the console, when creating a new record, the
hash 'ime_entries_by_date' in the validation method is empty, that's why
the record is saved without problems even if the worktime exceeds the
validation value of 1 day.
When updating the same record, the validation method catches well the error
but does not refresh the hash values even after I modify the work time
values to make it pass.
Any idea how to fix that?
Thank you
