Database Functions available in your Remix Supabase schema
Learn the most useful database functions in your schema
The database schema contains several functions that you can use so that you can extend your database with custom logic and RLS.
Check if a user is the Owner of an Account
This function checks if the user is the owner of an account. It is used in the accounts
table to restrict access to the account owner.
public.is_account_owner(account_id uuid)
This is true
if the account is the user's account or if the user created a team account.
Check if a user is a Member of an Account
This function checks if the user is a member of an account. It is used in the accounts
table to restrict access to the account members.
public.has_role_on_account( account_id uuid, account_role varchar(50) default null)
If the account_role
is not provided, it will return true
if the user is a member of the account. If the account_role
is provided, it will return true
if the user has the specified role on the account.
Check if a user is a team member of an Account
Check if a user is a member of a team account. It is used in the accounts
table to restrict access to the team members.
public.is_team_member( account_id uuid, user_id uuid)
Check if an account has permissions to action another account
This function checks if an account has permissions to action another account. It is used in the accounts
table to restrict access to the account owner.
public.can_action_account_member( target_team_account_id uuid, target_user_id uuid)
This function will:
- check if the current user is the owner of the target account: if so, return
true
- check if the target user is the owner of the target account: if so, return
false
- compare the hierarchy of the roles between the two accounts: if the current user has a higher role than the target user, return
true
This is useful to check if a user can remove another user from an account, or any other action that requires permissions.
Check Permissions
Check if a user has a specific permission on an account.
public.has_permission( user_id uuid, account_id uuid, permission_name app_permissions)
This function will return true
if the user has the specified permission on the account.
The permissions are specified in the enum app_permissions
. You can extend this enum to add more permissions.
Check if a configuration is set
Check if a configuration is set in the public.config
table.
public.is_set( field_name text)
Check if an account has an active subscription
Check if an account has an active subscription.
public.has_active_subscription( account_id uuid)
This means that the subscription status is either active
or trialing
. In other words, the account billing is in good standing (eg. no unpaid invoice)
This is important because just checking if the subscription exists is not enough. You need to check if the subscription is active, as the status can vary (eg. canceled
, incomplete
, incomplete_expired
, past_due
, unpaid
)
