"Learn the method for retrieving the number of rows in Cloud Code within the Parse platform

So I ran into an issue with this code - it keeps giving me a message that says success/error was not called.

Parse.Cloud.beforeSave("Offer", function(request, response) {
var duplicationQuery = new Parse.Query("Offer");

console.log(duplicationQuery.count);
});

After that, I made some changes:

Parse.Cloud.beforeSave("Offer", function(request, response) {
var duplicationQuery = new Parse.Query("Offer");
duplicationQuery.count()
{
    success: function(httpResponse) {
    console.log(httpResponse.text);
    response.success(httpResponse.text);
    console.log("Row count:   "+duplicationQuery.count);
},
     error: function(httpResponse) {
     console.error('Request failed with response code ' + httpResponse.status);
     response.error('Request failed with response code ' + httpResponse.status); 
 }
}

});

It seems like there might be an issue with the syntax. Any helpful suggestions would be greatly appreciated!

Answer №1

Avoid using count queries as they can be inefficient. Instead, perform a find query and retrieve the count by accessing the length property of the results.

var searchQuery = new Parse.Query("Offer");
searchQuery.limit(1000); // maximum limit
searchQuery.find().then( function(results) {
    console.log(results.length);
});

Keep in mind that the maximum number of records you can retrieve in a single query is limited to 1000.
