I'm using Parse.com as my backend and after Query how can I fill an array with all the data inside the Parse object? how can I avoid re-mapping? example:
$scope.addContList = contacts.map(function(obj) { // re-map!!!!
return {name: obj.get("name")}; // mapping object using obj.get()
});
I'm mapping my Parse object's properties one by one: name: obj.get("name"), etc. is there a better way?
$scope.addContList = [];
var ActivityContact = Parse.Object.extend("ActivityContact2");
var query = new Parse.Query(ActivityContact);
query.equalTo("activityId", $scope.objId);
query.find({
success: function(contacts) {
console.log("Successfully retrieved " + contacts.length + " contact.");
$scope.$apply(function() {
/*$scope.addContList = contacts.map(function(obj) {
return {name: obj.get("name")}; // mapping object using obj.get()
});*/
for (var i = 0; i < contacts.length; i++) {
$scope.addContList.push(contacts.ALL_PROPERTIES); // contacts.ALL_PROPERTIES does not exist, I'm looking a way to do that and avoid mapping?
}
});
console.log("--->>>"+JSON.stringify($scope.addContList, null, 4));
},
error: function(object, error) {
// The object was not retrieved successfully.
// error is a Parse.Error with an error code and message.
}
});
Should I use Underscore library, is that the only way to go?
I have seen some ppl using PFQuery but I don't know what is that, is PFQuery better for this?
Thanks!
The other answers are correct, but I think it's unnecessary to launch a digest cycle every time you add an item from contacts to $scope.addContList. Something like this should be sufficient:
query.find({
success: function (contacts) {
$scope.apply(function () {
// 1) shallow-copy the list of contacts...
// (this is essentially what you are trying to do now)
$scope.addContList = contacts.slice();
// or 2) just assign the reference directly
$scope.addContList = contacts;
// or 3) transform the Parse.Object instances into
// plain JavaScript objects
$scope.addContList = contacts.map(function (c) {
return c.toJSON();
});
});
},
error: function (object, error) {
// The object was not retrieved successfully.
// error is a Parse.Error with an error code and message.
}
});
Options 1) and 2) will correspond to a template similar to
<div ng-repeat="cont in addContList">{{ cont.get('name') }}</div>
while option 3) can be used like
<div ng-repeat="cont in addContList">{{ cont.name }}</div>
If you change
$scope.addContList = contacts[i];
to:
$scope.addContList.push(contacts[i]);
you should be good to go. Your previous code was re-assigning addContList to be each element in the contacts array, instead of adding the element to it. So at the end of your for loop, $scope.addContList would just be the last contact in your contacts array.
Change:
$scope.addContList = contacts[i];
to
$scope.addContList.push(contacts[i]);

I am trying to see if a value in the "apply" sublist for customer payment data has changed and do some action based on it.
My SuiteScript is as follows:
define(['N/record', 'N/https'],
function(record,https)
{
function afterSubmit(context)
{
var oldRec = context.oldRecord;
log.debug({title: 'oldRec ', details: oldRec });
// This log shows that the JSON has an
// attribute called sublists which contains "apply" which has all the applied payments
// eg: {"id":"1234", "type":"customerpayment", "fields":{all the fields},
// "sublists": {"apply" : {"line 1"...}}}
var oldRecSublists = oldRec.sublists;
log.debug({title: 'oldRecApply ', details: oldRecSublists });
// This returns empty or null though there is data
What am I doing wrong here?
Basically what I am trying to achieve is compare the context.oldRecord.sublists.apply and context.newRecord.sublists.apply to find if the amt has changed or not.
Is there a better way to do this is SuiteScript 2.0?
Thanks in advance!
Part of what is going on there is that it looks like you are trying to spelunk the NS data structure by what you see in the print statement. You are not using the NS api at all.
When you send the NS object to the log function I believe it goes through a custom JSON.stringify process so if you want to just inspect values you can do:
var oldRecObj = JSON.parse(JSON.stringify(oldRec));
now oldRecObj can be inspected as though it were a simple object. But you won't be able to manipulate it at all.
You should be using the NS schema browser
and referring to the help docs for operations on N/record
A snippet I often use for dealing with sublists is:
function iter(rec, listName, cb){
var lim = rec.getLineCount({sublistId:listName});
var i = 0;
var getV = function (fld){
return rec.getSublistValue({sublistId:listName, fieldId:fld, line:i});
};
var setV = function(fld, val){
rec.setSublistValue({sublistId:listName, fieldId:fld, line:i, value:val});
};
for(; i< lim; i++){
cb(i, getV, setV);
}
}
and then
iter(oldRec, 'apply', function(idx, getV, setV){
var oldApplied = getV('applied');
});
I'm trying to get HTML form data, loop it through, change it a bit and insert it to database. I have tried like below app.js.
How can I make callbacks so that formdata what I have modified is available for .create function?
I have searched from everywhere and I always end up in dead end and undefined variable somehow.
app.js:
//Find the day where to save
Day.findById(req.params.id, function(err, day) {
if (err) {
console.log(err);
res.redirect("/diary");
} else {
// Search function to find data with _id
function ingredientIdQuery(reqBodyId) {
var ingQuery = Ingredient.find({_id:reqBodyId});
return dbQuery;
}
// This loops through HTML formdata and formats it for mongoose model
for (var i = 0; i < req.body.amount.length; i++) {
if (req.body.amount[i] !== "") {
var amount = Number(req.body.amount[i]);
var singleMealTempObj = {};
singleMealTempObj.amount = amount;
var _id = req.body.id[i];
var query = ingredientIdQuery(_id);
// Executing the query for the data I need with id
query.exec(function(err, ingr){
if(err) {
return console.log(err);
} else {
singleMealTempObj.ingredient = ingr[0];
singleMealTempArr.push(singleMealTempObj);
}
});
}
}
}
// This inserts data into day
Meal.create(singleMealTempArr, function(err, singleMealObject) {
if (err) {
console.log(err);
} else {
day.meals.push(singleMealObject);
day.save();
res.redirect("/day/" + day._id + "/dayshow");
}
});
});
});
Edit:
Thanks for reply and notices! While I was trying to do everything to get this work I missed those few things like declaring variables. Sorry for that. I threw the towel in to the cage at this point.
flow goes like this:
User sends HTML form data to app.js which is inside object of two arrays (id[] and amount[]). Amount array needs to be looped through if it has value other than 0. Same index id array value is used to fetch data from database. This data what is found from database with id from id[] is used with same index amount[] and it should be saved to mongo.
I can get the values from HTML form ok. but I have tried to make a search in Mongo in a for loop (query.exec in the code) I get the data ok. When I log the data outside the database query, variable is undefined.
I hope this clarifys a bit what I'm trying to achieve.
I'll continue this later... :)
I guess issue originates because of this function.
function ingredientIdQuery(reqBodyId) {
var ingQuery = Ingredient.find({_id:reqBodyId});
return dbQuery;
}
Is find function asynchronous or synchronous?
Also you are returning dbQuery but dbQuery does not seem to be changed inside the function.
Couple I noticed that may fix this:
You never define singleMealTempArr, so when you try to push data to it, you are gonna run into problems.
Your ingredientIdQuery function returns dbquery - which also isn't defined. You actually call it ingQuery. Even so...are you positive that this will return the data that you want?
// lets loop through all the form fields in req.body.amount
for (var i = 0; i < req.body.amount.length; i++) {
// keep going unless the form field is empty
if (req.body.amount[i] !== "") {
// assign all the form fields to the following vars
var amount = Number(req.body.amount[i]);
var singleMealTempObj = {};
singleMealTempObj.amount = amount;
var _id = req.body.id[i];
var query = ingredientIdQuery(_id);
// we are executing the ingredientIdQuery(_id), better
// double-check that this query returns the result we are
// looking for!
query.exec(function(err, ingr){
if(err) {
return console.log(err);
} else {
singleMealTempObj.ingredient = ingr[0];
// now that we've gone through and mapped all the form
// data we can assign it to the singleMealTempArr
// WOOPS! Looks like we forgot to assign it!
singleMealTempArr.push(singleMealTempObj);
}
});
}
}
}
I'm using parse.com as the backend to my project and am creating a web page using javascript.
I'm extending PFObject as follow:
var Match = Parse.Object.extend("Match");
On the match object i have a couple properties, let say the first one is "player1"
My question is how can i make it so that when i try to get a property of my match object it succeeds
ie:
var matchQuery = new Parse.Query("Match");
matchQuery.find({
success: function (results) {
_.each(results, function (element, index, list) {
//
var test = element.player1 <<<< here player1 is undefined
})
},
error: function (error) {
alert("Error: " + error.code + " " + error.message);
}
});
Thanks for any tips!
Setting values on the backbone object works like regular JS. The value is retained for as long as the object is in memory, but no longer.
match.memoryOnlyAttribute = "I'll be gone soon";
If match is released and then queried again, memoryOnlyAttribute will be null, as you have observed.
To get a value for a property that persists, it must first be a property on the object. This is typically done in the data browser with the "+ Col" button. (It can also be done in code if your CLP permits).
With that done, the object can only be assigned persistent property values via the set() method...
var Match = Parse.Object.extend("Match");
var match = new Match();
match.set("player1", /* an object here that is of the right type */);
match.save();
Once the object is retrieved, the property in the parse data can be retrieved with the get() method...
matchQuery.first().then(function(matchResult) {
var player1 = match.get("player1");
// player1 will have a value
});
In my cloud code I want to retrieve the first object in the "Messages" class. Then i want to grab some information from that object, send it to another class, and finally delete that object from the "Messages" class i originally pulled it from. Below is my code, however it doesn't work. How should i rework this?
Should i use a different approach than the "destroy" method such as collection.remove?
Parse.Cloud.afterSave("sendMessage", function(Parse.Message, response) {
var body = null;
var senderName = null;
var senderId = null;
var randUsers = [];
var query = new.Parse.Query(Parse.Message);
query.find({
success: function(results){
body.push(results[1].get("messageBody"));
senderName.push(results[1].get("senderName"));
senderId.push(results[1].get("senderId"));
results[1].destroy({
success: function(results[1]){
//the first object in the class "Messages" was deleted
}, error: function(results[1], error){
//the first object was not deleted
}
});
response.success(getUsers);
}, error: funtion(error){
response.error("Error");
}
});
});
to avoid confusion: "getUsers" is an arbitrary function call.
Duplicate question with the entry;
Query entire class vs first object in the class
However, if you want to delete a specific object you need something which uniquely identify the
object. Then, one way is using the Parse object id to delete the object from class.
To delete the object via cloud, you need to use the destroy method of ParseObject. But if you have multiple objects then you can use destroyAll method. One example of ParseObject delete method on javascript API is below;
var yourClass = Parse.Object.extend("YourClass");
var query = new Parse.Query(yourClass);
query.get("yourObjectId", {
success: function(yourObj) {
// The object was retrieved successfully.
yourObj.destroy({});
},
error: function(object, error) {
// The object was not retrieved successfully.
// error is a Parse.Error with an error code and description.
}
});
Hope this helps,
Regards.
Some changes into above :
var missingDataQuery = new Parse.Query(missingDataObj)
missingDataQuery.equalTo('projectId',project);
var getMissingData = missingDataQuery.find({
success: function(yourObj) {
console.log('here')
yourObj[0].destroy({})
},
error: function(object, error) {
}
});
Here we getting object and then destroying it.
func deleteImage(imageId: String) {
let query = PFQuery(className: "ClassName")
query.whereKey("imageId", equalTo: "\(imageId)")
query.findObjectsInBackground {
(objects:[PFObject]?, error: Error?) -> Void in
if error == nil && (objects != nil) {
for object in objects! {
object.deleteInBackground()
print("object deleted")
}
}
}
}
I'm trying to convert my basic crud operations into an API that multiple components of my application can use.
I have successfully converted all methods, except the update one because it calls for each property on the object to be declared before the put request can be executed.
controller
$scope.update = function(testimonial, id) {
var data = {
name: testimonial.name,
message: testimonial.message
};
dataService.update(uri, data, $scope.id).then(function(response) {
console.log('Successfully updated!');
},
function(error) {
console.log('Error updating.');
});
}
dataService
dataService.update = function(uri, data, id) {
var rest = Restangular.one(uri, id);
angular.forEach(data, function(value, key) {
// needs to be in the format below
// rest.key = data.key
});
// needs to output something like this, depending on what the data is passed
// rest.name = data.name;
// rest.message = data.message;
return rest.put();
}
I tried to describe the problem in the codes comments, but to reiterate I cannot figure out how to generate something like rest.name = data.name; without specifying the name property because the update function shouldn't need to know the object properties.
Here is what the update method looked like before I started trying to make it usable by any of my components (this works)
Testimonial.update = function(testimonial, id) {
var rest = Restangular.one('testimonials', id);
rest.name = testimonial.name;
rest.message = testimonial.message;
return rest.put();
}
How can I recreate this without any specific properties parameters hard-coded in?
Also, my project has included lo-dash, if that helps, I don't know where to start with this problem. Thanks a ton for any advice!
Try like
angular.extend(rest,testimonial)
