    <p>I'm writing a <code>data</code> record to marshall a <code>JIRA</code> <code>JSON</code> object. The problem is, multiple objects have the same labels for name/value pairs. For example :</p> <p>(returned from curl and formatted)</p> <pre><code>{"expand":"schema,names" ,"startAt":0 ,"maxResults":2 ,"total":74 ,"issues":[ {"expand":"editmeta,renderedFields,transitions,changelog,operations" ,"id":"183614" ,"self":"https://10.64.16.44/rest/api/latest/issue/183614" ,"key":"BNAP-339" ,"fields":{"versions":[ {"self":"https://10.64.16.44/rest/api/2/version/28240" ,"id":"28240" ,"name":"2012-12-07" ,"archived":false ,"released":false } ] ,"status":{"self":"https://10.64.16.44/rest/api/2/status/1" ,"description":"The issue is open and ready for the assignee to start work on it." ,"iconUrl":"https://10.64.16.44/images/icons/status_open.gif" ,"name":"Open" ,"id":"1" } ,"description":"Do Re Mi Fa" ,"resolution":null } } ] </code></pre> <p>when I construct the problematic corresponding Haskell <code>data</code> records I get:</p> <pre><code>data Issue = Issue {expand :: String ,id :: String ,self :: String ,key :: String ,fields :: Fields } deriving Generic data Version = Version {self :: String ,id :: String ,name :: String ,archived :: Bool ,released :: Bool } deriving Generic </code></pre> <p>and 'id' and 'self' will clash. It occured to me I could solve this by just changing the names in the records and fixing it with a manually-created <code>FromJSON</code> instance. Any alternative solutions would be welcome.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
