Saving or Creating a Parse File in Parse Cloud code - parse-platform

I am trying to create a Parse cloud code function that would run a query and then put the results of the query in csv file and finally using the mailgun plugin send it out to a receipient.
Unfortunately I cannot figure out how to create a Parse File in cloud code. Suggestions?
Parse.cloud.define("exportDataViaEmail", function(request, response){
var query = new Parse.Query("Diaper");
var today = new Date();
var startTime = new Date(today - 1000 * 60 * 60 * 24 * (7*52+1));
query.lessThan("logCreationDate", today);
query.greaterThan("logCreationDate", startTime);
query.find({
success: {
//TODO I want store this in a Parse File but how?
},
error :{
}
});
})
/*
* Send email via mailgun
*/
Parse.Cloud.define("sendEmail", function(request, response){
Mailgun.sendEmail({
to: "myemail#gmail.com",
from: "hello#example.com",
subject: "Hello From example App",
text: "Using Parse and Mailgun is great!"
}, {
success: function(httpResponse) {
console.log(httpResponse);
response.success("Email sent!");
},
error: function(httpResponse) {
console.error(httpResponse);
response.error("Uh oh, something went wrong");
}
});
})

Using files in cloud code is easy and is thoroughly documented in the Parse Javascript Guide
It's as simple as var file = new Parse.File("myfile.txt", bytes);

Parse Server - How to delete image file from the server using cloud code

How can I delete an image's file from the server using Parse Cloud Code. I am using back4app.com
After Deleting Image Row
I am getting the images urls, then calling a function to delete the image using its url
Parse.Cloud.afterDelete("Image", function(request) {
// get urls
var imageUrl = request.object.get("image").url();
var thumbUrl = request.object.get("thumb").url();
if(imageUrl!=null){
//delete
deleteFile(imageUrl);
}
if(thumbUrl!=null){
//delete
deleteFile(thumbUrl);
}
});
Delete the image file from the server
function deleteFile(url){
Parse.Cloud.httpRequest({
url: url.substring(url.lastIndexOf("/")+1),
method: 'DELETE',
headers: {
'X-Parse-Application-Id': 'xxx',
'X-Parse-Master-Key': 'xxx'
}
}).then(function(httpResponse) {
console.log(httpResponse.text);
}, function(httpResponse) {
console.error('Request failed with response code ' + httpResponse.status);
});
}
for security reasons, not is posible to delete directly the image from Back4App, using DELETE from SDK or REST API. I believe that you can follow the guide below:
https://help.back4app.com/hc/en-us/articles/360002327652-How-to-delete-files-completely-
After struggling with this for a while it seems to be possible through cloud function as mentioned here. One need to use MasterKey in the cloud code:
Parse.Cloud.define('deleteGalleryPicture', async (request) => {
const {image_id} = request.params;
const Gallery = Parse.Object.extend('Gallery');
const query = new Parse.Query(Gallery);
try {
const Image = await query.get(image_id);
const picture = Image.get('picture');
await picture.destroy({useMasterKey: true});
await Image.destroy();
return 'Image removed.';
} catch (error) {
console.log(error);
throw new Error('Error deleting image');
}
});
For me it was first confusing since I could open the link to that file even after I deleted the reference object in the dashboard, but then I found out that the dashboard is not calling Parse.Cloud.beforeDelete() trigger for some reason.
Trying to download the data from the url after deleting the file through the cloud code function returns 0kB data and therefore confirms that they were deleted.

Session token empty for parse cloud code user query

I have written the following query to query a user with a given email and once found, return the session key.
Upon executing it returns an empty response.
I double checked that the user session entry actually exists and is linked to the user I am querying.
var query = new Parse.Query(Parse.User);
var email = request.params.email;
query.equalTo("email",email);
query.first({
success: function(user) {
Parse.Cloud.useMasterKey();
response.success(user.getSessionToken());
},
error: function(user, error) {
response.error(error);
},
useMasterKey: true
});
Ok, since you are using parse.com and not parse-server you need to write
the following line of code:
Parse.Cloud.useMasterKey();
in the first line because you tell cloud code that you want to use master key before you are executing any request to the server. Also it's better to use Promises (according to the best practices)
so at the end your code should look like this:
For running on parse.com
// in parse.com - it's the first thing that you do
Parse.Cloud.useMasterKey();
var query = new Parse.Query(Parse.User);
var email = request.params.email;
query.equalTo("email", email);
query.first().then(function(user) {
response.success(user.getSessionToken());
}, function(error) {
response.error(error);
});
For parse-server
in parse-server you use useMasterKey and send it to the function.
Parse.Cloud.useMasterKey(); will not work here.
// in parse-server - you send useMasterKey to the function
var query = new Parse.Query(Parse.User);
var email = request.params.email;
query.equalTo("email", email);
query.first({
useMasterKey: true
}).then(function(user) {
response.success(user.getSessionToken());
}, function(error) {
response.error(error);
});

Mandrill with parse server not working on heroku migration

I have migrate app from parse.com to heroku with mLab and everything works fine except cloud code.
I am using Mandrill for sending email from parse cloud code which is not working with heroku
Here is what I have done so far:
Installed mandrill ~0.1.0 into parse-server-example and push the code to heroku app
Put the cloud code into '/cloud/main.js'
Called the function from iOS app which respond error as:
[Error]: Invalid function. (Code: 141, Version: 1.13.0).
Here is my code script:
Parse.Cloud.define("sendMail", function(request, response) {
var Mandrill = require('mandrill');
Mandrill.initialize('xxxxxx-xxxxx');
Mandrill.sendEmail({
message: {
text: "ffff",
subject: "hello",
from_email: "xxxxx#gmail.com",
from_name: "pqr",
to: [
{
email: "xxxxxxxxxx#gmail.com",
name: "trump"
}
]
},
async: true
},{
success: function(httpResponse) {
console.log(httpResponse);
response.success("Email sent!");
},
error: function(httpResponse) {
console.error(httpResponse);
response.error("Uh oh, something went wrong");
}
});
});
But after calling 'sendMail' function I am getting this error:
[Error]: Invalid function. (Code: 141, Version: 1.13.0).
================================== MailGun ==========================
Parse.Cloud.define('hello', function(req, res) {
var api_key = 'key-xxxxxxxxxxxxxx';
var domain = 'smtp.mailgun.org';
var mailgun = require('mailgun-js')({apiKey: api_key, domain: domain});
var data = {
from: 'xxxxxxxald#gmail.com',
to: 'xxxxx8#gmail.com',
subject: 'Hello',
text: 'Testing some Mailgun awesomness!'
};
mailgun.messages().send(data, function (error, body) {
console.log(body);
});
//res.success(req.params.name);
});
I had a similar problem with sendgrid, but I finally find a way around the problem.
I think this steps may help you,
Miss some brackets or some code separator? ( try rewritting the entire code in the main.js )
The app is actually running? ( when you type "heroku open" in the terminal you get the default message? ) - if not check step 1.
If the previous are not working, rollback to a safe build and Add the add-ons in the heroku dashboard instead of installing them yourself, then download the git and do any changes to git and then push.
Below I have pasted from cloud code main.js code that is working using Mandrill on heroku parse application to send password recovery e-mail.
in cloud code main.js:
var mandrill_key = process.env.MANDRILL_KEY;
var Mandrill = require('mandrill-api/mandrill');
var mandrill_client = new Mandrill.Mandrill(mandrill_key);
{
success: function(gameScore) {
//alert('New object created with objectId: ' + gameScore.id);
mandrill_client.messages.send(
{
message: {
html: "<p>Hello " + firstUser.get('fullname') + ",</p><p>We received your request to reset your password.</p><p>Your user name is <strong>" + firstUser.get('username') + "</strong>. Please click here to create a new password. This link will expire in one hour after this mail was sent</p><p>If you need additional help, just let us know.</p><p>SampleCompany Support<br>customerservice#example.com</p><p>Copyright Sample Company, Inc. 2014-2017</p>",
subject: "Sample Company Name account recovery",
from_email: "customerservice#example.com",
from_name: "Sample Company Name",
to: [
{
email: firstUser.get('email'),
name: firstUser.get('fullname')
}
]
},
async: true
},
//Success
function(httpResponse) {
console.log(httpResponse);
//alert("Email sent!");
},
//Failure
function(httpResponse) {
console.error(httpResponse);
//alert("Uh oh, something went wrong");
});
},
error: function(gameScore, error) {
console.error(error.message);
//alert('Failed to create new object, with error code: ' + error.message);
},
useMasterKey: true
})

Parse query not returning

I am trying to do a little script on Cloud Code that sends an email whenever an object of type Reservas is created. This email needs to contain the information about the user that created this object. I know that using a related field would be better, but this option is not possible at the moment.
What I thought of doing is a query using the email from the Reservas object and the email property from the user but I can't seem to get to the line console.log("--> Usuario encontrado")
Here's what I tried to do:
Parse.Cloud.afterSave("Reservas", function(request) {
var assunto = "Reserva App Criada - ";
var conteudo = "Reserva App CRIADA\n"
try {
query = new Parse.Query(Parse.User);
query.equalTo("email", request.object.get("email"));
query.find({
sucess: function(usuario) {
console.log("--> Usuario encontrado")
mandarEmail(conteudo, assunto, request, usuario)
}, error: function(error) {
console.log("--> Usuario não encontrado")
emailErro(request, error);
}
})
} catch(err) {
console.log("--> Erro:" + err);
}
});
It was just a silly typo. I wrote sucess instead of success

parse.com cloud code can't send email via mandrillapp

I'm trying to send an email via parse.com via mandrill. The examples are very easy to follow, but I'm getting a strange error.
here is my code:
Parse.Cloud.afterSave("ip", function(request) {
var IPLogger_config = require('cloud/mandrillapp_config.js');
var Mandrill = require('mandrill');
Mandrill.initialize(IPLogger_config.mandrillAppKey);
console.log('within afterSave for ip');
console.log(request.object.id);
var ip = Parse.Object.extend("ip");
var query = new Parse.Query(ip);
query.descending("createdAt");
query.limit(2); // limit to at most 2 results
query.find({
success: function(results){
console.log('success query');
console.log('got ' + results.length + ' results');
var newestIp = results[0];
var olderIp = results[1];
if (newestIp.get('ip') == olderIp.get('ip') ) {
// the newest ip and the older one are equal, do nothing.
console.log('No ip change');
} else
{
console.log('ip change!');
console.log(Mandrill.initialize);
console.log(Mandrill.sendEmail);
Mandrill.sendEmail({
message: {
text: "The IP of your server has changed! The new ip is: " + newestIp.get('ip') ,
subject: "The IP of your server has changed!",
from_email: "parse#cloudcode.com",
from_name: "IPLogger",
to: [
{
email: IPLogger_config.your_email,
name: IPLogger_config.your_name
}
]
},
async: true
},{
success: function(httpResponse) {
console.log(httpResponse);
response.success("Email sent!");
},
error: function(httpResponse) {
console.error(httpResponse);
response.error("Uh oh, something went wrong");
}
});
}
},
error: function (error){
console.log('no success for query');
console.error("Got an error " + error.code + " : " + error.message);
}
});
});
my mandrillapp_config.js looks like this:
var IPLogger_config = {};
IPLogger_config.mandrillAppKey = "xxx";
IPLogger_config.your_email = 'myemail#bla.com';
IPLogger_config.your_name = 'myName';
The mandrillAppKey is correctly set. I double checked that. Sending email from mandrill website also works. I just created a new account and did no other settings on the mandrill site.
I'm getting this error: "code":-1,"name":"ValidationError","message":"You must specify a key value". In https://www.parse.com/questions/sometimes-getting-mandrill-you-must-specify-a-key-value-error-when-sending-email is written that the header might be wrong, but as you can see on my log, the "Content-Type":"application/json; charset=utf-8" is set correctly.

Where can be the problem? any ideas how to get it running?
thank you very much!
I finally found the problem. There was en error in the config script.
it need to look like this:
var IPLogger_config = {};
IPLogger_config.mandrillAppKey = "xxx";
IPLogger_config.your_email = 'myemail#bla.com';
IPLogger_config.your_name = 'myName';
exports.IPLogger_config = IPLogger_config;
in the main.jsfile, the resources of the config file need to be called like this:
var config = require('cloud/mandrillapp_config.js');
Mandrill.initialize(config.IPLogger_config.mandrillAppKey);
and now it works fine.
