Scriptrunner validator to search for a JQL and compare

[JIRA User]

I'm trying to find out how to write a validation with scriptrunner that checks if there are any existing issues with the same date as I've put in to a custom date field.

I have a custom date field: "Change Scheduled Date"

When I transition my issue it should check if there are any other issues (JQL) with the same date value as in my issue. If so, the transition should be blocked with a message "There are already changes planned on this date"

Any assistance would be much appreciated.

You could try

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.search.SearchProvider
import com.atlassian.jira.jql.parser.JqlQueryParser

import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.user.ApplicationUsers

def jqlQueryParser = ComponentAccessor.getComponent(JqlQueryParser.class)
def searchProvider = ComponentAccessor.getComponent(SearchProvider.class)
def issueManager = ComponentAccessor.getIssueManager()
def userManager = ComponentAccessor.getUserManager()
ApplicationUser user = userManager.getUserByName("soporte")

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def cf = customFieldManager.getCustomFieldObjectByName('Start date')


def myDate = cf.getValue(issue) as Date


String JQL='createdDate >= ' + myDate.format("yyyy-MM-dd") + ' and createdDate < ' + (myDate.plus(1).format("yyyy-MM-dd"))

def query = jqlQueryParser.parseQuery(JQL)
if (searchProvider.searchCount(query, user)>0){
return false
}
return true

in a simple script validator

Change the user and the field name
