I'm working on some cloud code right now where I have an id I query against which returns all the data for that row.
I then need to iterate over all the fields (columns) of data and make some changes to the values then update that row.
Im able to get the data from parse but im not sure how to pull out the PFObject keys to iterate over the data in a for loop , make changes then save.
Here is some sample code where I hardcoded a field value in but I'm not sure how to get the fields, then iterate over them in a for loop..
Also excuse the JS code, I its been years since I wrote any JS.
<script type="text/javascript">
Parse.initialize("xxxx", "xxxx");
var LocationTag = Parse.Object.extend("LocationTags");
var query = new Parse.Query(LocationTag);
query.equalTo("SomeId", "302d87f2-0188-4cbe-bc2c-e6dcbf822539");
query.find({
success: function(results) {
for (var i = 0; i < results.length; i++) {
var object = results[i];
var data = object.get('T0fYiV9PeeU'); <--- hardcoded field key.. i need to iterate over all fields returned from the row..
count = data.length;
for (var c = 0; c < count; c++) {
var res = Number(data[c].split(":")[0]);
text += "Value: " + res + "<br>";
sum += parseInt(res);
}
document.getElementById("main").innerHTML = text + ' sum: ' + sum + ' average: ' + sum/100 + results
}
},
error: function(error) {
alert("Error: " + error.code + " " + error.message);
}
});
Any ideas.. sorry again if its just a simple JS issue.. but I need to iterate over all fields, returned in the PFObject
If I understand correctly, you want a list of properties from a Parse.Object. The easiest way to to this is to call .toJSON() on the Parse.Object and then extract the keys from the json.
Example:
for (var i = 0; i < results.length; i++) {
var pfObject = results[i];
var jsonObject = pfObject.toJSON();
var pfKeys = [];
for(var key in pfKeys){
if(jsonObject.hasOwnProperty(key)){
pfKeys.push(key);
}
}
//Now we have a list of the pfObject keys in pfKeys
}

I want to convert the data of a Google Sheet into JSON format so that I can use it on my website. However, I get a 500 error whenever the website tries to fetch the JSON file.
I have already tried different methods to convert my sheet into JSON that are available on the internet
$url = 'https://spreadsheets.google.com/feeds/list/1dpmzzKNR8hRILX6qMD0KTruxxXYT3UAXR0EcX0zS0dE/1/public/full?alt=json';
$file= file_get_contents($url);
$json = json_decode($file);
$rows = $json->{'feed'}->{'entry'};
return $rows;
I had the same problem; I was able to work around the problem by parsing the html from the pubhtml page directly to output a similar JSON format:
Instead of using the Google Sheet ID, use the link for "Publish to Webpage".
There are some rows that I skip since some are for frozen rows, but you should be able to modify the code to your needs.
function importGoogleSheets(publishedUrl, sheetId, onSuccess, onError) {
var headers = [];
var rows;
$.ajax({
url: publishedUrl+'?gid='+sheetId+'&single=true',
success: function(data) {
data = $.parseHTML(data)[5];
htmldata = data;
rows = data.getElementsByTagName('tr');
for (var i = 0; i < rows[1].cells.length; i++) {
headers[i] = 'gsx$' + rows[1].cells[i].textContent.toLowerCase().replace(/[^0-9a-z]*/g, '');
}
for (var i = 3; i < rows.length; i++) {
temp = {};
for (var h = 1; h < headers.length; h++) {
temp[headers[h]] = {'$t': rows[i].cells[h].textContent};
}
all_data[i - 3] = temp;
}
onSuccess(all_data);
},
error: function(data) {
onError(data);
}
});
}
One note though is that it includes any empty rows unlike the feed, so you may want to filter the ouptut based on some column.
Here I have tis function that is querying data and returning it to me and im putting that data in to html elements to make a post.my if statement at the bottom is where im having a bit of problem i trying to only apply my comment window once to the new clones once they have been pushed over to the new div called story board, i believe im telling my if statement that if the class already exists in that new clone then do nothing else apply it there.. to seee what i am talking about...here is my test domain...http://subdomain.jason-c.com/
sign in is "kio" pass is the same and when you hit publish on the stories, everytime a nw one hits it will apply comment box to a post in the storyboard window that already has a comment text area. what am i doing wrong.
function publishWindowHandler(){
var query = new Parse.Query('Post');
console.log(currentUser);
query.equalTo("User", currentUser);
query.include("User");
query.descending("createdAt")
console.log(user.get('username'));
query.find({
success:function(results){
document.getElementById("publishCenter").textContent = "";
for(var i =0; i < results.length; i++){
var userPost = results[i];
//console.log(userPost.get("User") + " / " + userPost.get("Author") + " / " + userPost.get("Story") + " / " + userPost.get("objectId"));
var authorTitle = document.createElement("p");
var newPost = document.createElement("P");
var title = document.createElement("P");
var userLabel = document.createElement("p");
var postId = userPost.id;
var postBtn = document.createElement("INPUT");
postBtn.className ="publishBtn";
postBtn.id ="publishBtn";
postBtn.setAttribute("Type", "button");
postBtn.setAttribute("value", "Publish");
title.textContent = "Story: " + userPost.get("Title");
authorTitle.textContent = "Author: " + userPost.get("Author");
newPost.textContent = userPost.get("Story");
userLabel.textContent = "Published by: " +userPost.get("User").get ("username");
var postWrapper = document.createElement("DIV");
postWrapper.className = "postWrapper";
postWrapper.id = postId;
document.getElementById("publishCenter").appendChild(postWrapper);
postWrapper.appendChild(title);
postWrapper.appendChild(authorTitle);
postWrapper.appendChild(newPost);
postWrapper.appendChild(userLabel);
postWrapper.appendChild(postBtn);
postBtn.addEventListener("click", publicViewHandler);
function publicViewHandler(){
$(this).parent(".postWrapper").clone().appendTo(".storyBoard");
function testWindow(){
if($(publicBoard).children().hasClass(".commentWindow")){
}
else
{
$(".storyBoard").children().append(commentWindow);
}
}
testWindow();
}
}
}
})
}
According to the documentation, jquery hasClass doesn't need '.' prefixing the passed in class name.
https://api.jquery.com/hasclass/
Try removing that and see if that get's you anywhere.
Also, where is the variable commentWindow defined? Is it global?
var myClone = $(this).parent().clone(true);
myClone.appendTo(".storyBoard");
console.log(publicBoard);
console.log("hello",$(this));
console.log($(publicBoard).find('.postWrapper').find("commentWindow"));
myClone.append($(commentWindow).clone());
this is what i ended up doing to solve my issue took me a while and a little help from a friend.
I'm trying to query the Parse User Class but I'm not getting any results. The User class has a column labeled "phone", and I'm passing an array of dictionaries where each dictionary has a key "phone_numbers" that corresponds to an array of phone numbers. I'm trying to determine if a User in my table has one of those phone numbers. I'm not getting any errors running the code, but there does exist a user in my table with a matching phone number. What am I doing wrong?
Parse.Cloud.define("hasApp", function(request, response) {
var dict = request.params.contacts;
var num = 0;
var found = 0;
var error = 0;
var phoneNumbers = "";
for (var i = 0; i < dict.length; i++){
var result = dict[i].phone_numbers;
num += result.length;
for (var j = 0; j < result.length; j++){
phoneNumbers += result[j] + ", ";
var query = new Parse.Query(Parse.User);
query.equalTo("phone", result[j]);
query.find({
success: function(results) {
found = 1;
},
error: function() {
error = 1;
}
});
}
}
response.success("hasApp " + dict.length + " numbers " + num + " found " + found + " error " + error + " phoneNumbers " + phoneNumbers);
});
My response from calling this is
hasApp 337 numbers 352 found 0 error 0 phoneNumbers "list of phone numbers"
where some of those phone numbers appear in my User class. As far as I can tell I'm not getting any errors but I'm also not successfully querying the User table
UPDATE
After moving
response.success("hasApp " + dict.length + " numbers " + num + " found " + found + " error " + error + " phoneNumbers " + phoneNumbers);
to the body of the success block, I get the following error because I'm only allowed to call response.success once per cloud function.
Error Domain=Parse Code=141 "The operation couldn’t be completed. (Parse error 141.)"
UserInfo=0x14d035e0 {code=141, error=Error: Can't call success/error multiple times

at Parse.js:2:4531}
Does this mean that I'm only able to verify one phone number at a time? So I can't pass an array of phone numbers and get the PFUser objects corresponding to those phone numbers (if they exist)?
I understand that my internal query to Parse.User is happening synchronously with my "hasApp" call, so is there a way to query Parse.User asynchronously? That way I can respond back to the client after checking all the phone numbers?
You can use Parse.Promise to solve logic where you need to iterate through O(n) number of database queries in one asynchronous Cloud Code definition:
var _ = require("underscore"),
isEmpty = function (o) { // standard function to check for empty objects
if (o == null) return true;
if (o.length > 0) return false;
if (o.length === 0) return true;
for (var p in o) {
if (hasOwnProperty.call(o, p)) return false;
}
return true;
};
Parse.Cloud.define("hasApp", function (request, response) {
var dict = request.params.contacts,
users = [];
var promise = Parse.Promise.as();
_.each(dict, function (obj) {
_.each(obj.phone_numbers, function (num) {
promise = promise.then(function () {
var promiseQuery = new Parse.Query(Parse.User);
promiseQuery.equalTo("phone", parseInt(num));
return promiseQuery.find({
success: function (result) {
if (isEmpty(result)) // don't save empty results e.g., "[]"
return;
users.push(result); // save results to a model to prevent losing it in scope
}
});
});
});
});
return promise.then(function () {
response.success("Found user(s): " + JSON.stringify(users));
});
});
Note a few things about this block:
You can append functionality iteratively to a Parse.Promise.
You can loose scope of database results in your iteration. Use a local array model to save your query results to. Although, I presume there is a better way to achieve the same functionality without the use of a user model, someone else can quote me on that.
Pay close attention to the way Parse handles data. For example, if you are storing your phone numbers as numbers, you have to make sure you use parseInt() when querying for it.
Be aware that you must attach your response.success() function to your promise to assure it is resolved after your iterations have run. From this block, your response from Parse will look similar to an array of User objects. You can decide on the many different ways you can save the data model depending on what you need it for.
As a final note, this block doesn't account for any validation or error handling that should be accounted for otherwise.
The problem seems to be that your response.success call is happening before the query can even happen. While you have response.success calls in your query success block, they are never called because you return success before the query is executed.
Try commenting out the line:
response.success("hasApp " + dict.length + " numbers " + num + " found " + found + " error " + error + " phoneNumbers " + phoneNumbers);
This should let the code go to your query, and maybe move it into the success block of your query.
Let me know if this works.
You're now calling response.success in a loop now. You should only call response.success/response.error once per cloud function.
It would help if you can show the original code with no commented out lines (to show your original intention) and the new code with no commented out lines as two separate code samples.
Querying a Parse.User is fairly easy and well explained in the documentation, here is an example taken from it
var query = new Parse.Query(Parse.User);
query.equalTo("gender", "female"); // find all the women
query.find({
success: function(women) {
// Do stuff
}
});
For your case it will be something like this:
Parse.Cloud.define("getAllFemales", function(request, response) {
var query = new Parse.Query(Parse.User);
query.equalTo("gender", "female"); // find all the women
query.find({
success: function(women) {
// Do stuff
}
});
});
Hope it helps, as always more info on the Documentation
I am writing a cloud function that has a query:
var query = new Parse.Query("A");
query.ascending("age");
After the find comes back I iterate through the results:
query.find({
success: function(results){
// here I iterate through and want to iterate through expecting to follow the sort...
for (var i = 0; i < results.length; ++i) {
a = results[i];
console.log(("found A object after save, age = "+ a.get("age"));
}
},
error:function(......
........
})
The problem is that the log does not print the "a" object ordered by age.
How can I iterate through the A objets here in order, so following the age sorting the query should give me back?
I want to set i to 0 of the first item from a json criteria, eg. if the criteria is green in this case the i will start from 3... if criteria = blue it will start on 2... i need to set it to start from 0 or 1 whether it is.. also how to count total of a criteria, eg. green total is 2,, blue=1, red=2... thanks in advance!
var myBox_html ="";
var i = 0;
function createDiv(1x,2x,3x) {
A = '<something>'+1x;
B = '<something>'+2x;
C = '<something>'+3x;
myBox_html += '<something-more>'+A+B+C;
}
criteria // is a parameter from url, in this case means green
get_it = function(doc) {
var jsonData = eval('(' + doc + ')');
for (var i=0; i<jsonvar.name.length; i++) {
var 1x = jsonvar.name[i].1;
var 2x = jsonvar.name[i].2;
var 3x = jsonvar.name[i].3;
if (1x == criteria){
var Div = createDiv(1x,2x,3x);
} else {null}
}
document.getElementById("myBox").innerHTML = myBox_html;
}
get_it();
json should look like this:
var jsonvar = {"name":[{"1":"red","2":"round","3":"fruit"},{"1":"red","2":"squared","3":"box"},{"1":"blue","2":"squared","3":"box"},{"1":"green","2":"squared","3":"box"},{"1":"green","2":"pear","3":"fruit"}]};
Consider several solutions:
1: Generate criteria-grouped JSON response on the server-side. E.g.
var jsonvar = '{"name":{
"red": [{"1":"red","2":"round","3":"fruit"}, {"1":"red","2":"squared","3":"box"}],
"blue": [{"1":"blue","2":"squared","3":"box"}],
"green":[{"1":"green","2":"squared","3":"box"}, {"1":"green","2":"pear","3":"fruit"}]}}';
2: Convert you JSON array to criteria-grouped format as defined above. Here is sample routine for such a grouping:
function group_elements (arr) {
var result = {};
for (var i=0; i < arr.length; i++) {
if (!result[arr[i][1]]) {
result[arr[i][1]] = [];
}
result[arr[i][1]].push(arr[i]);
}
return result;
}
Both solutions allows you to iterate only filtered records and count length of group.
