Copy Custom field value from one field to another

[Pushpkant Garg]

My requirement is to copy Text field data into USer picker field. Text Field data has single email address.

When I used script runner "Copy custom field" option it gave me type casting error. 

Can anyone please help me with groovy script which will help me to update the same. We have around 30k+ records which need to be updated.

To expand on @Vasiliy Zverev's answer a bit, you could get the results of a JQL query in a console script, then iterate through the list of values to update them.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.UpdateIssueRequest
import com.atlassian.jira.issue.search.SearchProvider
import com.atlassian.jira.jql.parser.JqlQueryParser
import com.atlassian.jira.security.JiraAuthenticationContext
import com.atlassian.jira.web.bean.PagerFilter

def jqlQueryParser = ComponentAccessor.getComponent(JqlQueryParser)
def searchProvider = ComponentAccessor.getComponent(SearchProvider)
def issueManager = ComponentAccessor.getIssueManager()
def jiraAuthenticationContext = ComponentAccessor.getJiraAuthenticationContext()
def user = jiraAuthenticationContext.getUser()

// edit this query to suit
def query = jqlQueryParser.parseQuery("summary is not EMPTY")

def results = searchProvider.search(query, user, PagerFilter.getUnlimitedFilter())

log.debug("Total issues: ${results.total}")


def customFieldManager = ComponentAccessor.getCustomFieldManager()
def cfUser = customFieldManager.getCustomFieldObjectByName("userFiledName")
def cfEmail = customFieldManager.getCustomFieldObjectByName("emaiFiledName")

def emailUserMap = ComponentAccessor.getUserManager().getAllApplicationUsers().collectEntries {
    [(user.getEmailAddress()): user]
}

results.getIssues().each { documentIssue ->
    log.debug(documentIssue.key)

    // if you need a mutable issue you can do:
    def issue = issueManager.getIssueObject(documentIssue.id)

    issue.setCustomFieldValue(cfUser, emailUserMap.get(issue.getCustomFieldValue(cfEmail)))
    UpdateIssueRequest updateIssueRequest = UpdateIssueRequest.builder().eventDispatchOption(EventDispatchOption.ISSUE_UPDATED).sendMail(false).build()

    issueManager.updateIssue(user,
        issue,
        updateIssueRequest)
    
    // do something to the issue...
    log.debug(issue.summary)
}

Here is script for script console to update single issue

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.UpdateIssueRequest
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.user.ApplicationUser

Map<String, ApplicationUser> emailUserMap = new HashMap<>();
for(ApplicationUser user: ComponentAccessor.getUserManager().getAllApplicationUsers()){
    emailUserMap.put(user.getEmailAddress(), user)
}

CustomField cfUser = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("userFiledName")
CustomField cfEmail = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("emaiFiledName")

MutableIssue issue = ComponentAccessor.getIssueManager().getIssueObject("issueKey");

issue.setCustomFieldValue(
        cfUser
        , emailUserMap.get(issue.getCustomFieldValue(cfEmail))
)

UpdateIssueRequest updateIssueRequest = UpdateIssueRequest.builder().eventDispatchOption(EventDispatchOption.ISSUE_UPDATED).sendMail(false).build()

ComponentAccessor.getIssueManager().updateIssue(
        ComponentAccessor.getJiraAuthenticationContext().getUser()
        , issue
        , updateIssueRequest
)

You've answered your own question really.  Fields have to contain compatible data types for a simple copy to work.  A text string is not a user object.

You'll need to write a bit of code that can look up the email address, and find a user  with that email address (you'll need to check for duplicates with a rule, even if it's just "the first one I find")
