====== Scripted Validators ======

Following scripts can be used for scripted validators within the workflow

=== Verify project name ===

<code java>
issue.projectObject.name == "My First Project Name"
</code>

=== Require Value in FIELD2 if FIELD1 = 'Yes' ===
<code java>
if ( cfValues['FIELD1']?.value == 'Yes') { 
    if ( cfValues['FIELD2'] ) {
        return true
    } 
    else return false
     }
 else return true
</code>

=== Require Value in DATEFIELD2 greater than "NOW" if FIELD1 is set ===
<code java>
Date today123 = new Date()
if ( cfValues['FIELD1'] ) { 
    if ( cfValues['DATEFIELD2'].getTime() > today123.getTime() ) {
        return true
    } 
    else return false
     }
 else return true
</code>

=== Check if field equals some string ===
<code java>
def selectedSegment = cfValues['Segment']
def selectedSegmentString = selectedSegment.toString()
if ( selectedSegmentString.equals("Some String") ){
    // do something here

}
</code>

=== Verify if custom field value is 5 characters long ===
<code java>
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.IssueManager;

def customfield_ID = "customfield_11700"
def issueManager = ComponentAccessor.getIssueManager()
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def cField = customFieldManager.getCustomFieldObject(customfield_ID)
def cFieldValue = issue.getCustomFieldValue(cField).toString()


if (cFieldValue.size() != 5){
    return false
}
else{
    return true
}
</code>

=== Verify if any other tickets have the same dates as requested ===

=== Validate user changed the OD Environment field if it was "None" previously ===

=== Allow only specific users in project ABC or users in a group "JIRAGROUP" to create issues validator ===

<code java>
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
def groupManager = ComponentAccessor.getGroupManager()

(issue.projectObject.key == 'ABC' && issue.issueType.name == 'Bug' && currentUser.name in ["XYZ", "TEST"] ) || groupManager.isUserInGroup(currentUser, "JIRAGROUP")


</code>

=== Only allow users in group "users" to execute this action ===

<code java>
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
def groupManager = ComponentAccessor.getGroupManager()

groupManager.isUserInGroup(currentUser, "users")
</code>

=== Check if user is in group "users" or project role "Developers" to execute this action ===

<code java>
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.security.roles.ProjectRoleManager

def projectManager = ComponentAccessor.projectManager
def projectRoleManager = ComponentAccessor.getComponent(ProjectRoleManager)

if (groupManager.isUserInGroup(currentUser, "users") || projectRoleManager.isUserInProjectRole(currentUser, role, issue.getProjectObject())){
	return true
}
</code>

=== Check if cascading child drop down is set to "None" ===
The following script was found on Atlassian community here: [[https://community.atlassian.com/t5/Jira-questions/How-to-check-the-second-value-of-a-cascading-select-list-in-a/qaq-p/759808|How to check the second value of a cascading select list in a custom field]]
Use the **Custom Validator** for this script-runner script.
<code java>
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.opensymphony.workflow.InvalidInputException

def issue = issue as MutableIssue
def cf = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("CascadingSelect")
def cfValue = issue.getCustomFieldValue(cf) as HashMap

def parentOption = cfValue.values().getAt(0)?.value
def childOption = cfValue.values().getAt(1)?.value

if (!childOption) {
    throw new InvalidInputException("Child option is Null")
}
