nested attributes change value before save with cocoon

I have a project model:

class Project < ApplicationRecord
   has_many  :site_visits, inverse_of: :project, dependent: :destroy

   accepts_nested_attributes_for :site_visits, allow_destroy: true, reject_if: :all_blank

   before_save: :convert_site_visit_dates

   def convert_site_visit_dates
     begin
       if self.site_visits_attributes.present?
         self.site_visits_attributes.each do |site_visit|
            site_visit[1]['visit_date'] = convert_date(site_visit[1]['visit_date']) if site_visit[1]['visit_date'].present?
            site_visit[1]['_destroy'] = true if site_visit[1]['_destroy'] == "1"
         end
       end
     rescue StandardError
       nil
     end
   end 

end

I have site_visit model: (columns - visit_date)

class SiteVisit < ApplicationRecord

  belongs_to  :project

end

Before saving the site_visits in any particular project through cocoon gem I need to change the value of the site_visits_attributes using a callback. In my project model you can see I've defined a callback to change the visit_date column of site_visit table. But the value is not changing. Thus, in the database null values are being saved.

Any idea what's wrong?

site_visits_attributes is not a method on the Project object. If you remove rescue StandardError you'll catch this issue.

It is probably a better idea to modify the data in a before_filter in your controller. Or alternatively, you could modify the data on before_save on the SiteVisit objects.
