NFEED VERSION 5.12 AND LOWER
Nfeed is a JIRA add-on allowing to integrate external information into the context of an issue. This information can come from databases, web-services or other sources.
For instance, it can be used to show customer information such as a telephone number, address and so on, which has been looked-up from a CRM database.
This add-on is particular in the way that the information is stored. Instead of storing the information which is showed in the issue, it only stores an identifier of that information allowing to lookup the actual values.
There are 2 challenges manipulating this data especially when each side of a synchronisation relation is using a different data store.
Looking up nfeed values
The challenge when synchronizing these custom fields between two instances, is that the values needs to be looked up in the same way as nfeed does. As the add-on doesn't provide a JIRA level API to actually do this look up, a workaround needs to be used.
NFeed provides a REST Api allowing to extract the values as showed in the issue. Below is a snippet allowing to use this REST api to extract the required information
// NFeed REST Api returns a json which needs to be parsed. Using the JsonSlurper import groovy.json.JsonSlurper // A generic function which can be reused for accessing rest resourses def getNfeedValue = { String issueKey, customFieldId -> URL url; def baseURL = "http://foo.exalate.net/rest/nfeed/1.0/customfield"; String userpass = "user:password"; String basicAuth = "Basic " + new String(new Base64().encoder.encode(userpass.getBytes())); // GET the value using the 'Export' method url = new URL(baseURL + "/${issueKey}/${customFieldId}/EXPORT"); URLConnection connection = url.openConnection(); connection.requestMethod = "GET" connection.setRequestProperty ("Content-Type", "application/json;charset=UTF-8") connection.setRequestProperty ("Authorization", basicAuth); connection.connect(); // Parse the JSON String jsonString = new Scanner(connection.getContent(),"UTF-8").useDelimiter("\A").next(); def jsonSlurper = new JsonSlurper() def jsonObject = jsonSlurper.parseText(jsonString) // the display contains the value displayed in an issue return jsonObject.displays } replica.customKeys.Products = getNfeedValue(issue.key, "customfield_10302")
Storing nfeed values
To be able to store nfeed values, one needs to understand how the custom field is configured.
In the example below, nfeed depends on a table 'audience_d2' which is stored in the JIRA database.
The code will
- Open a connection to the database
- Retrieve the right id from the table based on values provided by the remote instance
- Set the local custom fields to the found id.

How to connect to a mysql database
Here is an example to connect to a mysql database
import groovy.sql.Sql // connect to db def sql = Sql.newInstance("jdbc:mysql://localhost:3306/test", "user", "password", "com.mysql.jdbc.Driver") // execute a simple query sql.eachRow("SELECT city, zipcode from cities"){ row -> // print data returned by the query println "City = $row.city - Zipcode = $row.zipcode" } // close the connection - don't forget !!! sql.close()
