I am trying to delete a mass amount of records from my database. My destroy_all keeps getting stopped when a callback fails to destroy a record because of ActiveRecord::RecordNotFound
. I want to skip the callbacks when the error ActiveRecord::RecordNotFound
occurs on records that the callback is trying to delete.
All User records belong to school via a UserSchool relation. I am trying to delete all User Records where the school_id
: 74 is present in any UserSchool record.
user_ids = UserSchool.where(school_id: 74).map(&:user_id)
User.where(id: user_ids).destroy_all
The result is:
ActiveRecord::RecordNotFound: Couldn't find Comment with 'id'=17
I want to skip over that error and continue destroying User records. How can I rescue here?
user_ids = UserSchool.where(school_id: 74).map(&:user_id)
users = User.where(id: user_ids)
users.each do |user|
begin
user.destroy
rescue => ActiveRecord::RecordNotFound
puts "Record not found"
end
end
I think we can rescue by looping it over each object.
user_ids.each do |user_id|
User.find(user_id).destroy rescue nil
end
For only ActiveRecord::RecordNotFound
exception you could do,
user_ids.each do |user_id|
begin
Contact.find(user_id).destroy
rescue => ActiveRecord::RecordNotFound
puts "Record not found"
end
end
