ServiceNow Application Developer Part 6

Access to the Code Review Requests module Cderevdeleonptimale: nOtninesotafntche following -A user with the admin role on the parent instance -A user with the teamdev_code_reviewer role on the parent instance

-A user with the teamdev_user role on the registered

exclusion policy

Developers can create an _____________ to prevent pushes or pulls to particular instances in the team development hierarchy

code review

Team Development administrators can require that pushes undergo ___________ before accepting pushes

code review

When enabled, pushing a change to the parent instance triggers the ____________ workflow

Code Review Workflow

Notifications are sent out by the ______________ to thereviewers group when: -A push requires code review -A user cancels a push

Code Review Workflow

-Starts when changes are pushed to the parent instance -Verifies that the code review property is active on the parent instance -Sets the stage of changes requiring approval to Awaiting Code review -Notifies the Team Development Code Reviewers group to review the pushed changes -Loads approved changes or set the stage to Code Changes Rejected

Update Set

A group of configuration changes that can be moved from one instance to another

Update Set

Allows administrators to group a series of changes into a named set and then move them as a unit to other systems for testing or deployment

True

True//False: Update sets track customizations where the table has an "update_synch" dictionary attribute

update set

An ___________ is an XML file that contains: -A set of record details that uniquely identify the update set -A list of configuration changes -A state that determines whether another instance can retrieve and apply configuration changes

special handlers

Things tracked with _____________: -Workflows -Form sections -Lists -Related lists -Choice lists -System dictionary entries -Field labels

False

True//False: More than one update set can be the default set for any application scope

ServiceNow Best Practices for Update Sets

-Do not delete update sets, if an update set is deleted, any         updated record maybe overwritten in the next update

-Do not include the system_id field from the ldap_server_config record in an update set, this points to the wrong system_id for the target instance and does not work

-Do not back out the Default update set, causes damage to the system

-Never change the Update Set field value in a Customer Update record

-Do not mark an update set as Complete until it is ready to

migrate. Once complete, do not change it back to "In progress". -Do not manually merge updates into an update set, always use the Merge Update Set module -If a committed update set has a problem in the test instance, build the fix in another update set in the development instance -Always preview an update set before committing it -Set completed update set on the production instance to "Ignore" -Keep a to-do list of manual changes and data loads that need to be completed after an update set is applied -Do not make too many changes at one time, verify that the correct changes have been made incrementally

Auto Map Matching Fields

Which utility is used to determine if field names in an Import Set match the field names on the target table when importing data into ServiceNow?

Good fit for ServiceNow

-Data can be modeled in a relational database -Extensive use of forms to interact with data -Needs reporting -Needs workflow to manage processes

Bad fit for ServiceNow

-Data is unstructured such as audio or video -Requires "as-is" use of low level programmatic libraries -Multiplayer games or apps that need a game engine -No process flow through application

False

True//False: ServiceNow is good for real-time data delivery and update form external sources

False

True//False: ServiceNow is good for media streaming

How to get to the mobile version of the application

Form Header

Form element: Provides navigation tools and actions related to the record

Sections

Form element: Stores specific data about the record

Related links

Form element: Provides access to additional functions based on record type and system setup. Administrators can add related links to form using UI actions.

Related lists

Form element: Displays records in other tables that have relationships to the current record.

Embedded lists

Form element: Allows for editing related lists without having to navigate away from the form. Changes are saved when the form is saved.

Response time indicator

Form element: Appears at the bottom of some forms to indicate the processing time required to display the form.

Form Designer

Drag and drop interface used to: -Create form layouts -Create form views -Create and delete form sections -Add fields to tables

Fields, Field Types

Components of the Field Navigator

Fields

A list of all fields from the selected table that are not already part of the form layout

Field Types

A list of data types that can be used to create new table fields. The Form Layout is used to create and edit fields, sections, and annotations

onLoad, onChange, onSubmit, onCellEdit

The Client Script Types:

Active

Option in the configuration that controls whether the script is enabled. Inactive scripts do not execute.

control, oldValue, newValue, isLoading, isTemplate

The parameters for the onChange function

GlideForm (g_form) Class

______________ client-side API provides methods for managing form and form fields including methods to: -Retrieve a field value on a form -Hide a field -Make a field read-only -Write a message on a form or a field -Add fields to a choice list

GlideUser (g_user) Class

_________________ API provides methods and non-method properties for finding information about the currently logged in user and their roles

Yes

g_user.hasRole('x_foo_app_user'), does this return true for the admin role?

Client-side debugging	-JavaScript Log and jslog()
& UI Policies debugging	-Field Watcher
	-Try/catch
	-Debugging tools built into web browsers (browser
	dependent)

Field Watcher

Tracks and displays information about actions ServiceNow performs on a form field

UI Policies

Client-side logic which governs form and form field behavior. Unlike Client Scripts, UI Policies do not always require scripting

UI Policy Actions                   Client-side logic in a UI Policy used to set three field                                   

attributes:

-Mandatory

-Visible -Read-Only

UI Policy Scripts

Client-side API to execute script logic based on whether the UI Policy conditions tests true or false

-Business Rules -Script Includes

Two types of server-side scripts:

Business Rules

Server-logic which execute when database records are queried, updated, inserted, or deleted

Before, After, Async, Display

The "When" options for Business Rules:

Before

Business Rules execute their logic before a database operation occurs

After

Business Rules execute their logic immediately after a database operation occurs and before the resulting form is rendered for the user

Async

Business Rules execute asynchronously

Display

-Business Rules execute their logic when a form loads and a record is loaded from the database -Processed when a user requests a record form -Primary objective is to use a shared scratchpad object, g_scratchpad, which is also sent to the client as part of the form.

Condition Field

Used to specify when the Business Rule script should execute

Business Rules

_____________ often use the current and previous objects in their script logic

current

____________object • Automatically instantiated from GlideRecord class • Properties are all fields for a record and all the GlideRecord methods • Property values are values as they exist in the runtime environment
