Code-based document editing with CouchBase

Question

Code-based document editing with CouchBase

To test Couchbase, I need to create a servlet that will edit 1,000 JSON documents by changing the value of '"flag": false' to '"flag": true'. How can I achieve this task?

Here is my view code for finding documents with '"flag": false':

function (doc, meta) {  
    if (meta.type == "json" && doc.flag === false) {        
        emit(doc.flag, null);
    }
}

Below is my servlet code for printing results:

doGet(....
View view = client.getView("des1", "flag");
Query query = new Query();
query.setIncludeDocs(true);
ViewResponse result = client.query(view, query);
for(ViewRow row : result) {
  resp.getWriter().println(row.getId());  
}

Apologies for any language errors in my explanation)

Answer №1

To make changes to the fields within a JSON document, you need to follow a specific process. First, retrieve the documents you wish to update from the view. Next, convert these documents into Java objects. Edit the desired property, such as the "flag," within the Java object. Then, serialize the modified Java object back into JSON format and replace the original document with the updated one. One useful tool for handling the conversion between Java objects and JSON is GSON.
