CouchDB Views

As always, refer to the manuals for the best documentation. The easiest way to create views is within CouchDB Futon (the web interface). Click on the mvp_sensor_data database to navigate down into it, then under the menu “View” go to the “temporary view” and create a new one (or edit an existing one). Click on the “View Code” window arrow to drop down the code editing window. The view I created has the following code:

 function(doc) {
      if(doc.value && doc.attribute && doc.status == 'Success')
      {
          emit([doc.attribute, doc.name, doc.timestamp], doc);
      }
 } 

The bottom window shows the query results. Click on “Save As” and save it in the _design/doc file as “attribute_value”

This view returns more data than you want, you will use query parameters within the curl http to select subsets of these records.
