Conflict Checker

The scheduling configuration has been improved as part of Golive 9.23. If you are using Golive 9.23 or a newer version, please refer to the Scheduling Environments section. If you are using an older version of Golive, consider upgrading. Alternatively, you can refer to the documentation below for configurating your environment scheduling.

When you book an environment, you need to make sure you are not booking it on the same timeslot than a colleague. In our basic use case, we rely on the Timeline to visualize potential conflicts. If you want to go further and highlight or block conflicting booking requests, read further…

Highlight Conflicts with ScriptRunner

If you are using the ScriptRunner Jira App, you can display potential conflicts on your booking screen:

1. Add a new Script

After installing the ScriptRunner Jira App, add our script in the Script Editor (code reference below).

New Script in the Script Editor section (check below for the code)

The folder hierarchy (com/apwide/behaviour) should correspond to the import line you have in your script (point 3 below): import com.apwide.behaviour.ConflictChecker

You can ignore the warnings displayed in the script editor, about some classes (environment, ctx) unknown at this stage.

2. Add a new Behaviour

Then, create a new Behaviour and map it with your Booking Request project and issue type.

New entry in the Behaviour section

3. Call the Script from your Behaviour

In your Behaviour, create an Initialiser Script: and call the Conflict Checker script we added previously:

And copy-paste the following code in the opened text area to call our Conflict Checker script:

CODE 
package com.apwide.behaviour

import com.apwide.behaviour.ConflictChecker
import com.onresolve.scriptrunner.runner.customisers.WithPlugin
import com.onresolve.scriptrunner.runner.customisers.PluginModule
import com.apwide.env.api.GoliveAccessor
import org.apache.log4j.Level

@WithPlugin("com.holydev.env.plugin.jira-holydev-env-plugin")
@PluginModule
GoliveAccessor goliveAccessor

new ConflictChecker(
    ctx: this,
    golive: goliveAccessor.golive(),
    issueTypeName: "Booking Request",
    startDateFieldName: "Start time",
    endDateFieldName: "End time",
    environmentFieldName: "Environment(s) to book",
    helpFieldName: "Environment(s) to book",
    timelineUrl: "/secure/ApwideGolive.jspa#/home/timeline?view=timeline318",
    dateFormat: "MMM d",
    blocking: false,
    showDependencies: true,
    logLevel: Level.DEBUG
).check()

Script Parameters:

  • issueTypeName: your Booking Request issue type name

  • startDateFieldName: your booking start date/time field name

  • endDateFieldName: your booking end date/time custom field name

  • environmentFieldName: your Environment custom field name

  • helpFieldName: the name of the field under which the warning message should appear (if not defined, it will be your endDateFieldName)

  • timelineUrl: URL used in the warning message “Open the Timeline” button

  • dateFormat: date format used for the period (if not defined, it will be your Jira date format)

  • blocking: do you need to block the request creation (true) or not (false) in case of detected conflict. When the blocking parameter is set to true, the warning banner will be displayed in red:

  • showDependencies: decide to show (true) or hide (false) the list of dependencies of booked environments (with blue background on the screenshot)

  • calendarId (optional): ID of a Scheduled Event Calendar to include in the conflict detection. Calendars' IDs (Integer) can be found in the “Shared Calendars” section (HTML source code). This parameter is optional and does not appear in the script examples below.

In order to check for conflicts each time the fields are updated in your Booking Request, add the 3 fields in your Behaviour:

  • Environment field

  • Start time field

  • End time field

Mark them as “Required” using the first toggle, and for each of them, add the same Server-side scripts used than for “Initialiser”:

Here an exmple for the “End time” field

All scripts contained by the same behaviour must be identical. We recommend you to store the code in a common script file shared by the Initialiser and the Fields instead of copying the code.
