Danger

☠️ The commands listed here cause irrecoverable data loss! Only proceed if you know what you’re doing and you have a backup!

Note

Please note that this is not a full command list, if you’re missing commands, feel free to ask over at the Community.

Removing tickets (and their articles)¶

# Delete a ticket (specified by database ID)
>> Ticket.find(4).destroy

# Delete all tickets
>> Ticket.destroy_all

# Keep some tickets (specified by database ID); delete the rest
>> tickets_to_keep = [1, 2, 3]
>> Ticket.where.not(id: tickets_to_keep).destroy_all

Removing users¶

Warning

Customers may not be deleted while they have tickets remaining in the system.

As such, the examples below will delete not only the specified customers, but all tickets associated with them, as well. Below commands remove upon executing without any further warnings.

Hint

If you’re not sure what to do and need to learn more about what Zammad does upon removing users, please consider using Zammad’s UI options in stead.

Our documentation for the data privacy function will help you a lot!

Removing users is possible in 2 ways: A single user and in bulk.

>> User.find_by(email: '<email address>').destroy

>> User.where(
      email: ['<email address 1>', '<email address 2>']
   ).destroy_all

Removing organizations¶

Note

Removing an organization does not delete associated customers.

Step 1: Select organizations

# by "active" status
>> organizations = Organization.where(active: false)

# by name
>> organizations = Organization.where(name: 'Acme')

# by partial match on notes
>> organizations = Organization.where('note LIKE ?', '%foo%')

Step 2: Preview affected organizations

>> puts organizations.map { |org| "ORGANIZATION #{org.name}" }.join("\n")

Step 3: Proceed with deletion

>> organizations.each do |org|
     puts %{Preparing deletion of organization "#{org.name}"...}

     org.members.each do |member|
        puts "  Removing #{member.fullname} from organization..."
        member.update!(organization_id: nil)
     end

     puts "  Deleting #{org.name}..."
     org.destroy
   end

Removing system records¶

# Remove all online notifications
>> OnlineNotification.destroy_all

# Remove all entries from the Activity Stream (dashboard)
>> ActivityStream.destroy_all

# Remove entries for all recently viewed objects
# (tickets, users, organizations)
>> RecentView.destroy_all

# Remove all history information from tickets, users and organizations
# (dangerous!)
>> History.destroy_all
