- Switches:
- -no_perm_check (optional, boolean)

If the group's join policy is 'needs approval' then default_member_state will return 'needs approval'. If the group's join policy is closed then an error will be thrown, unless the no_complain flag is set, in which case empty string is returned.

Creates a group of this type by calling the .new function for the package associated with the given group_type. This function will fail if there is no package.
There are now several ways to create a group of a given type. You can use this Tcl API with or without a form from the form system, or you can directly use the PL/SQL API for the group type.
Examples:
# OPTION 1: Create the group using the Tcl Procedure. Useful if the # only attribute you need to specify is the group name db_transaction { set group_id [group::new -group_name "Author" $group_type] } # OPTION 2: Create the group using the Tcl API with a templating # form. Useful when there are multiple attributes to specify for the # group template::form create add_group template::element create add_group group_name -value "Publisher" db_transaction { set group_id [group::new -form_id add_group $group_type ] } # OPTION 3: Create the group using the PL/SQL package automatically # created for it # creating the new group set group_id [db_exec_plsql add_group " begin :1 := ${group_type}.new (group_name => 'Editor'); end; "]
- Switches:
- -form_id (optional)
- The form id from templating form system (see example above)
- -variable_prefix (optional)
- -creation_user (optional)
- -creation_ip (optional)
- -group_id (optional)
- -context_id (optional)
- -group_name (optional)
- The name of this group. This is a required variable, though it may be specified either explicitly or through
form_id
- -pretty_name (optional)
- Parameters:
- group_type (optional, defaults to
"group"
)- The type of group we are creating. Defaults to group which is what you want in most cases.
- Returns:
group_id

group::party_member_p (public)
group::party_member_p [ -party_id party_id ] [ -group_id group_id ] \ [ -group_name group_name ] [ -subsite_id subsite_id ]
Return 1 if the party is an approved member of the group specified. One can specify a group_id (preferred) or a group name. Note: The group name is not unique by definition, and if you call this function with a duplicate group name it will return the first one (arbitrary)!!! Using the group name as a parameter is thus strongly discouraged unless you are really, really sure the name is unique.
The party must have specifically been granted membership on the group in question.
- Switches:
- -party_id (optional)
