g_om Details

2.4.22.1 Details

Intrexx provides a wide range of extended options for process-controlled user management. With access objects and methods, new users, among other things, can be created and managed in Groovy actions. The globally available, pre-initialized object "g_om" serves as an entry point for the portal organizational structure in processes. With this object, principle use cases such as searching for a user or generating a new password can be implemented. These methods can be used as "normal" method calls. All available methods can be found in our JavaDocs:

Class GroovyOrgBuilder

Class GroovyOrgStructureWrapper

Examples

// Change the password of the stated user.
g_om.changePassword(g_session.user, "SECRET")

// Generate and send a new password to the stated user.
g_om.generateAndSendPassword(g_session.user)

// Get a user using a GUID.
def user = g_om.getUser("C10579449052F85D9C3FF3C2824348FCE020A22E")

// Classify a list of GUIDs. A list with GUIDs can
// be transferred or a text (e.g. content of a multiple selection data field).
def guids = ["AE39A904172F5867DA23DE289D1D6B7967420DC0", "6AA80844C3C99EF93BF4536EB18605BF86FDD3C5", g_session.user.guid]
			 
def classified = g_om.classifyGuids(guids) //guids = Collection or String

//The result is a map with the categorized GUIDs.
//e.g. {containers=[], users=[7312F993D0DA4CECCA9AE5A9D865BE142DE413EA], 
//      unclassified=[AE39A904172F5867DA23DE289D1D6B7967420DC0], 
//      sets=[6AA80844C3C99EF93BF4536EB18605BF86FDD3C5]}
println(classified)

//Additional filters for specific object types
println(classified.users)
println(classified.containers)
println(classified.sets)
println(classified.unclassified)

//Returns the number of non-anonymous sesssions
g_om.getNonAnonymousActiveSessionCount()

In addition, the object "g_om" has access to more methods that can be called in conjunction with a closure to implement subsequent actions. These methods can be recognized by the stated parameter in the JavaDocs with the type "groovy.lang.Closure", such as "GroovyOrgBuilder.createUser(groovy.lang.Closure p_closure)". Within such a closure, methods of any class can be called that are documented in each of the defined links. The following methods can be called with a closure:

g_om.createUser(groovy.lang.Closure p_closure)

A new Intrexx user can be created with this. At the same time, the properties listed below can be set within the closure. The properties "name" and "loginName" are mandatory and the others are optional.

For the properties "container" and "memberOf", you can choose whether to enter the GUIDs or the unique names of the containers, roles, sets, groups and paths in the organizational structure.

Example

g_om.createUser {
	name      = "g_om"
	loginName = "g_om"
	birthday  = now()
	container = "0F8233A39555B28F6B32CFFE666A5151E1F41AD3"
	memberOf = ["8FBF199EE826D16742F0F131E0AB4CF0E6BA6CA3", "Users"]
	emailBiz  = "g_om@example.org"
	guid      = newGuid()
	male      = true
}

g_om.getLoggedOnUsers(boolean p_bIncludeAnonymous, groovy.lang.Closure p_closure)

Returns all currently logged-in users. "p_bIncludeAnonymous" allows you to define whether anonymous sessions should be included in the result. Additional filters can be applied via the Groovy closure.

Example

def userOnline = g_om.getLoggedOnUsers(false) {
	it.containerGuid == "9DABA9EE4F9F6F771704F75C79A1C3A124FF399C"
}

g_om.getLoggedOnUsersDistinct(groovy.lang.Closure p_closure)

Returns all currently logged-in, non-anonymous users without double entries. Additional filters can be applied via the Groovy closure in the same way as "g_om.getLoggedOnUsers(boolean p_bIncludeAnonymous, groovy.lang.Closure".

g_om.withOrgStructure(groovy.lang.Closure p_closure)

Allows you to work in the portal organizational structure.

Example

g_om.withOrgStructure {
	println("9DABA9EE4F9F6F771704F75C79A1C3A124FF399C".isUser())
}

The following methods can be called within the OrgStructure closure:

isUser()
isSet()
isGroup()
isDistList()
isContainer()
isOrganization()
isOrgUnit()

g_om.getMembers(java.lang.Object,boolean)

Generates a list of the GUIDs of all users that belong to a specific or multiple groups.

Example

def userGuids = g_om.getMembers(["00A303288634E154D755732E478F2BE0D9AD36F7"], false)*.guid

"00A303288634E154D755732E478F2BE0D9AD36F7" is the GUID of the group copied from the from the Users module. Multiple group GUIDs or set GUIDs can be entered. More information is available here:

2.4.24. g_permissions

This class is intended to check and query permissions. The usage is demonstrated in the template "JSON response" for the corresponding use case. checkPermission(Permission) and check(Closure) check whether the desired permissions have been granted. Otherwise, a java.security.AccessControlException is thrown. hasPermission(Permission) and has(Closure) function in the same way but return a Boolean value that states whether the requested permissions have been granted or not. The closure methods delegate to the above-mentioned GroovyIxAccessControllerDelegate object and demand a map that assigns actions to the object names.

Example

Check application permissions for the application <application GUID>, read permission for the data group <data group GUID> and write permission for the data group <another data group GUID>.

g_permissions.check {
    application("<application GUID>": "access")
    dataGroup("<data group GUID>": "read", "<another data group GUID>": "write,create")

2.6.2. Intrexx database API

2.6.2.1. Prepared statement with SELECT

Executes a SELECT statement as a prepared query. Afterwards it is iterated over the results in the result set.

Example

stmt = g_dbQuery.prepare(conn, "SELECT * FROM DATAGROUP('7AFAF7CB5DE281D35F05D96FCD96CE27692C110F') WHERE ID = ?")
stmt.setInt(1, 1)
stmt.executeQuery()
stmt = Safely.close(stmt)

Snippet

import de.uplanet.scripting.groovy.util.Safely

def conn = g_dbConnections.systemConnection
def stmt = null
def rs   = null

try
{
	stmt = g_dbQuery.prepare(conn, "SELECT <COLUMNS> FROM DATAGROUP('<DATAGROUP_GUID>') WHERE <CONDITION>")
	
	//stmt.setInt(1, 1)
	
	rs = stmt.executeQuery()
	
	while (rs.next())
	{
		// do something
		// rs.getIntValue(1)
		// rs.getStringValue(2)
		// rs.getBooleanValue(3)
		// rs.getTimestampValue(4)
	}
	
	rs   = Safely.close(rs)
	stmt = Safely.close(stmt)
}
finally
{
	rs   = Safely.close(rs)
	stmt = Safely.close(stmt)
}

2.6.2.2. Prepared statement with INSERT

Executes an INSERT statement as a prepared query.

Example

stmt = g_dbQuery.prepare(conn, "INSERT INTO DATAGROUP('7AFAF7CB5DE281D35F05D96FCD96CE27692C110F') (ID, STRTEXT, DTDATE, BBOOLEAN) VALUES (?,?,?,?)")

stmt.setInt(1, 1)
stmt.setString(2, "Example text")
stmt.setTimestamp(3, now().withoutFractionalSeconds)
stmt.setBoolean(4, true)

Snippet

import de.uplanet.scripting.groovy.util.Safely

def conn = g_dbConnections.systemConnection
def stmt = null

try
{
	stmt = g_dbQuery.prepare(conn, "INSERT INTO DATAGROUP('<DATAGROUP_GUID>') (<COLUMNS>) VALUES ()")
	
	//stmt.setInt(1, 1)
	//stmt.setString(2, "Example text")
	//stmt.setTimestamp(3, now().withoutFractionalSeconds)
	//stmt.setBoolean(4, true)
	
	stmt.executeUpdate()

	stmt = Safely.close(stmt)
}
finally
{
	stmt = Safely.close(stmt)
}

2.6.2.3. Prepared statement with INSERT (with closure)

Executes an INSERT statement with a closure as a prepared query.

Example

def conn = g_dbConnections.systemConnection

g_dbQuery.executeUpdate(conn, "INSERT INTO DATAGROUP('7AFAF7CB5DE281D35F05D96FCD96CE27692C110F') (LID, STRTEXT, DATE) VALUES (?,?,?)") {
	setInt(1, 1)
	setString(2, "Example text")
	setTimestamp(3, now().withoutFractionalSeconds)
}

Please note:
If the statement should be used multiple times, e.g. within a loop, the prepared statement version without a closure is more efficient.

Snippet

def conn = g_dbConnections.systemConnection

g_dbQuery.executeUpdate(conn, "INSERT INTO DATAGROUP('<DATAGROUP_GUID>') (<COLUMNS>) VALUES ()") {
	//setString(1, "Example text")
	//setTimestamp(2, now().withoutFractionalSeconds)
	//setBoolean(3, true)
}

2.6.2.4. Prepared statement with UPDATE

stmt = g_dbQuery.prepare(conn, "UPDATE DATAGROUP('7AFAF7CB5DE281D35F05D96FCD96CE27692C110F') SET STRTEXT = ?, DTDATE = ?, BBOOLEAN = ? WHERE ID = ?")

stmt.setString(1, "Example text")
stmt.setTimestamp(2, now().withoutFractionalSeconds)
stmt.setBoolean(3, true)
stmt.setInt(4, 1)

stmt.executeUpdate()
stmt = Safely.close(stmt)

Snippet

import de.uplanet.scripting.groovy.util.Safely

def conn = g_dbConnections.systemConnection

	setString(1, "Example text")
	setTimestamp(2, now().withoutFractionalSeconds)
}

Please note:
If the statement should be used multiple times, e.g. within a loop, the prepared statement version without a closure is more efficient.

Snippet

def conn = g_dbConnections.systemConnection

g_dbQuery.executeUpdate(conn, "UPDATE DATAGROUP('<DATAGROUP_GUID>') SET <COLUMNS> = ? WHERE <CONDITION>") {

2.17.3. Define an error handler for a script

Usable in

Groovy pages
Action and rendering handlers

Snippet

onError = { exception, err ->
	err.title = ""
	err.description = "Insert your description here. ${exception.message}"
}

2.18. Groovy server scripts

2.18.1. JSON response

Please note that a permissions check (IxAccessController) is required before any action that is triggered by a user.

Snippet

response.json()

// define an error handler
response.onError = {e, err ->
	//err.type = "default"
	// either title/description, ...
	err.title = "my error"
	err.description = e.message
	err.showEmbedded = true
	// ... or a redirect
	// err.redirectUrl = "http://www.example.org/"
	// err.redirectDelay = 1500 // milliseconds
}

// check permissions
g_permissions.check {
	// application("${application.guid}": "access")
	// dataGroup("<data group GUID>": "read", "<another data group GUID>": "write,create")
}

// create some JSON content
writeJSON("person": [
	givenName: "Donald",
	lastName: "Duck",
	age: 78,
	nephews: ["Huey", "Dewey", "Louie"]
])

Possible variations of the script above

Closure without or with exactly one parameter

If the closure declares a parameter, the exception that occurred is transferred to the closure in the first parameter (e).

Snippet

// define an error handler
response.onError = {e ->
    writeJSON("error": "Something bad happened.")
}

Closure with two parameters

The exception that occurred is transferred to the closure in the first parameter (e) and a ErrorResponseData object is transferred in the second parameter (err). The ErrorResponseData object can be configured in the closure according to the respective requirements.

Snippet

// define an error handler
response.onError = {e, err ->
    //err.type = "default"
    // either title/description, ...
    err.title = "my error"
    err.description = e.message
    err.showEmbedded = true
    // ... or a redirect
    // err.redirectUrl = "http://www.example.org/"
    // err.redirectDelay = 1500 // milliseconds
}

With a string

The stated string is sent to the client in the response body.

Snippet

response.onError = '{"error": "Something bad happened."}'

Assign another object

In a JSON response scenario, an attempt is made to generate JSON from the object. If the response is not JSON, an attempt is made to output the object in a suitable manner as text.

Snippet

response.onError = [
    "error": "Something bad happened.",
    "solace": "But things could be worse."
]

// add additional variables to the Velocity context
// vc.put("PreparedQuery", g_dbQuery)
// vc.put("variableName", variableValue)
