Module Description

SAAS Subscription Trial - DB Filter Extension. Adds DB Filter server group configuration to trial packages, enabling trial subscriptions to be deployed on DB Filter servers.

Dependencies

• sadeem_subscription_trial
• sadeem_saas_dbfilter

Extension

This module extends the trial package with a DB Filter Server Group field. When the subscription type is set to dbfilter, the trial system uses the server group to auto-select the best DB Filter server for the trial subscription.

Additional Trial Package Fields

1. Subscription Type - Extended with DbFilter option
2. DB Filter Server Group - Server group for auto-assigning trial subscriptions (required when type is dbfilter)

How It Works

1. Trial package is configured with type DbFilter and a server group
2. Customer submits trial form
3. System creates trial request and subscription
4. The server group's get_best_server() selects the optimal server
5. All server-related fields (IP, ports, domain, Cloudflare, Nginx) are auto-populated
6. Subscription is confirmed and deployed on the selected DB Filter server

Key Fields

Trial Package — DBFilter additions (sadeem.subscription.trial.package inherit)

Key Actions

Warnings & Important Notes

• Server group required: _validate_subscription_creation raises ValidationError if subscription_type = 'dbfilter' and no dbfilter_server_group_id is configured on the trial package.
• No new models: This module only inherits and extends existing models.
• subscription_type cleared: @api.onchange clears dbfilter_server_group_id when switching away from dbfilter type.
