To get a data from the firestore I queried a document and get that data into variable. Now, I need to use that variable in other part of the code.
when I am using that variable it does not get any data . How to resolve these error.
var d1;
var getdata = respond.get()
.then(doc =>{
if(!doc.exists){
console.log('No such document');
}else{
console.log('Document data:', doc.data());
d1 = doc.data();// In d1 I am not getting the data of that document
}
}).catch(err => {
console.log('Error getting documnet', err);
});
Here in for loop, I am using the d1 variable. But it is not executing these for loop
for(var k in d1){
var p = d1[k].PhoneNumber;
let rph = respond.where(receiverph ,"==", p)
.set({
Status : status
});
let payload = {
notification : {
title: "Message",
body: msg,
sound:"default",
}
};
console.log(payload);
return admin.messaging().sendToDevice(token,payload).then((response) =>{
console.log(token);
console.log("Successfully sen notification");
}).catch(function(error){
console.warn("Error sending notification",error);
});
}
});
In d1 the data is
{ Invite2: { PhoneNumber: 917893659558, Amount: 33 },
Invite1: { PhoneNumber: 917799266509, Amount: 33 },
Invite3: { Amount: 33, PhoneNumber: 918639146409 }
}
Use Promisse.all
let promise = [];
let all = [];
for(var k in d1){
var p = d1[k].PhoneNumber;
let rph = respond.where(receiverph ,"==", p)
.set({ Status : status });
let payload = {
notification : {
title: "Message",
body: msg,
sound:"default",
}
};
console.log(payload);
return admin.messaging().sendToDevice(token,payload).then((response) =>{
console.log(token);
console.log("Successfully sen notification");
}).catch(function(error){
console.warn("Error sending notification",error);
});
}
promise.push(rhp);
});
Promise.all(promise).then((data)=>{
data.forEach(query => {
query.forEach(res=>{
all.push(res.data());
})
})
When you get a document with .get, the document has to be fetched from the database. Therefore this operation is asynchronous and you must wait until the document is received before you can iterate on its data. In short, it should look something like the following:
some_doc_ref.get().then(doc => {
if (doc.exists) {
var d1 = doc.data();
for(var k in d1) {
//...
}
}
});
Hope that helps.
Hi i am using nightmare for scrape data from website and also course details. I occur a issue :-
err: { message: 'navigation error',
code: 0,
details: 'OK',
url: 'https://www.myskills.gov.au/courses/details?Code=CHC14015' }
on each url traversal. Please suggest me to resolve this:
var Nightmare = require('nightmare')
var vo = require('vo')
var fs = require('fs')
var filesystem = require('file-system')
// var nightmare = Nightmare({show:true});
var sleep = require('sleep');
vo(run)(function(err, result) {

console.log("1st step *run");
yield nightmare
.goto('https://www.myskills.gov.au/courses/search/')

.evaluate(function () {
var hrefs = [];
$('.search-result h4 a').each(function()
{
var course = new Object();
course.title = $(this).html();
course.link = $(this).attr('href');
course.code = $('.search-result .col-md-2.text-small
span').html();
hrefs.push(course);
});
return hrefs;
})
.then(function(str){
console.log("2nd step evaluate then on page load");
console.log(str);
for(var i=0; i< 8; i++)
{
console.log(i);
sleep.sleep(1);
var link = "https://www.myskills.gov.au";

console.log("Hi in run1");
//console.log(result);

function *run1() {
console.log("I 2nd time:-"+i);
console.log(coursesinglelink);

My case:
app.js:
let app = angular.module('myApp', []);
app.controller('login', function ($scope, $login) {
$scope.account = {};
$scope.loginForm_submit = function ($event, account) {
$event.preventDefault();
if ($login.isValid(account)) {
$login.submit(account);
// goal:
$login.submit(account).then(function () {
window.location = '/'
}, function (msg) {
console.log(msg)
});
}
};
});
login.js:
app.factory('$login', function () {
let o = {
isValid: function (x) {
let success = false;
// validating...
return success
},
submit: function (x) {
// prevent to force submitting
if (this.isValid(x)) {
let formData = new FormData(), xhttp = new XMLHttpRequest();
// appending data to 'formData' via 'x'...
xhttp.onreadystatechange = function () {
if (xhttp.readyState === XMLHttpRequest.DONE) {
let data = JSON.parse(xhttp.responseText);
if (data['Success']) {
// return then() with successCallback() function
} else {
let msg = data['ErrorMessage'];
// return then() with errorCallback() function
}
}
}
xhttp.open('POST', '/account/register');
xhttp.send(formData);
}
}
}
return o
});
data is an object like:
let data = {
'Success': false,
'ErrorMessage': 'Invalid login attempt.'
};
I want to return then() method after submitting to access result. How can I do that?
UPDATE:
In controller:
[HttpPost]
public async Task<ObjectResult> Login(LoginViewModel model)
{
IDictionary<string, object> value = new Dictionary<string, object>();
value["Success"] = false;
if (ModelState.IsValid)
{
// login
value["Success"] = true;
}
return new ObjectResult(value);
}
First of all, you should avoid using $ for your own functions.
About your problem, you need to use $q. And you should use what angular offers to you.
Let me give you this :
app.factory('loginFactory', function($q, $http) {
var ret = {
isValid: isValid,
submit: submit
}
return ret;
function isValid(x) {
// Your code ...
return false;
}
function submit(x) {
// x is your form data, assuming it's a JSON object
var deferred = $q.defer();
// Assuming you're posting something
$http.post('yoururl', x,{yourConfigAsAnObject: ''})
.then(function(success){
console.log(success.data);
deferred.resolve(success.data);
}, function(error) {
console.log(error);
deferred.reject(error);
});
return deferred.promise;
}
});
Now, in your controller, you can use
loginFactory.submit(yourParam).then(function(success){
// Your code
}, function(error) {
// Your code
});
app.factory('$login', function ($q) {
let o = {
isValid: function (x) {
let success = false;
// validating...
return success
},
submit: function (x) {
var d = $q.defer();
// prevent to force submitting
if (this.isValid(x)) {
let formData = new FormData(), xhttp = new XMLHttpRequest();
// appending data to 'formData' via 'x'...
xhttp.onreadystatechange = function () {
if (xhttp.readyState === XMLHttpRequest.DONE) {
let data = JSON.parse(xhttp.responseText);
if (data['Success']) {
// return then() with successCallback() function
d.resolve('success');
} else {
let msg = data['ErrorMessage'];
d.reject(msg);
// return then() with errorCallback() function
}
}
}
xhttp.open('POST', '/account/register');
xhttp.send(formData);
}
else {
d.reject('error');
}
return d.promise;
}
}
return o
});
dude,I made a sample function with promise
$q should be injected as dependency
class AppUserService {
constructor($http,CONFIG_CONSTANTS,$q, AuthService) {
this.API_URL = CONFIG_CONSTANTS.API_URL;
this.$http = $http;
this.$q = $q;
this.api_token = AuthService.api_token;
}
getAppUserList() {
const deferred = this.$q.defer();
this.$http.get(`${this.API_URL}/customer?api_token=${this.api_token}`)
.success(response => deferred.resolve(response))
.error(error => deferred.reject(error));
return deferred.promise;
}
}
its in ES6 form.
How to use:
AppUserService.getAppuserList().then(success => {
// code for success
},error => {
// code for error
})
submit: function (x) {
return $q(function (resolve, reject) {
// prevent to force submitting
if (this.isValid(x)) {
let formData = new FormData(), xhttp = new XMLHttpRequest();
// appending data to 'formData' via 'x'...
xhttp.onreadystatechange = function () {
if (xhttp.readyState === XMLHttpRequest.DONE) {
let data = JSON.parse(xhttp.responseText);
if (data['Success']) {
resolve(data);
// return then() with successCallback() function
} else {
let msg = data['ErrorMessage'];
reject(msg);
}
}
}
xhttp.open('POST', '/account/register');
xhttp.send(formData);
}
else
reject('x not valid');
}
}
}
But I recommended to use angular $http service.
I have this code on my meteor app:
// client side
Template.lead.events({
'submit .insertExternalAccountForm': function (event) {
event.preventDefault();
Session.set('mcsStatus', 'Creating external account ...');
var target = {
code: event.target.code.value,

};
var noFormError = true;
if (target.username.length === 0) {
Session.set("username_error", "Field must not be empty");
noFormError = false;
} else {
Session.set("username_error", null);
}
if (target.password.length === 0) {
Session.set("password_error", "password must not be empty");
noFormError = false;
} else {
Session.set("password_error", null);
}
if (!noFormError) {
return noFormError;
}
Meteor.call('createExternalAccount', target, function (err, res) {
if (err) {
console.error(err);
}
console.log('in meteor call');
Router.go('/' + res.domain + '/' + res.externalId);
});
}
});
//server side
var createExternalAccountSync = function (query, external) {
return models.SearchSources.findOne(query).exec()
.then(function (searchsource) {
external.domain = searchsource.source;
var emr = searchsource.source.split('-');
return models.Organization.findOne({externalId: emr[2]}).exec();
}).then(function (org) {
console.log('after org');
external.organizationId = org._id;
return models.AppUser.findOne({clientId: external.clientId, externalId: external.clientUserId }).exec();
}).then(function (user) {
console.log('after app user');
external.userId = user._id;
external.userIds = [user._id];
return new Promise(function (resolve,reject) {
console.log('saveOrUpdate');
models.ExternalAccount.saveOrUpdate(external, function (err, newE) {
if (err) {
console.error(err)
reject(err);
}
resolve(newE)
});
});
})
.catch(function (e) {
console.error(e);
throw new Meteor.Error(e);
});
};
Meteor.methods({'createExternalAccount': function (data) {

} else {
query.searchSourceId = data.searchSourceId;
}
newExternalAccount.searchSourceId = query.searchSourceId;
console.log('creating external account')
createExternalAccountSync(query, newExternalAccount)
.then(function (external) {
console.log('should return to meteor call');
return external;
})
.catch(function (e) {
console.error(e);
throw new Meteor.Error(e);
});
}
});
The problem that I'm having is that the code on the server side, while it's being called properly, is not triggering the client side meteor.call, there's no console.log output or anything. I believe that the Meteor.wrapAsync method is properly used, but still not showing anything on the client side, and not in fact redirecting where I want the user to go after form submission.
UPDATE
The code has being updated to the newest form, but now I'm getting a weird error on the client, and its actually because the meteor.call method on the template returns neither error or result

By the code you provided,it could be because you are calling different method.
You defined 'createAccount' but on client side you are calling 'createExternalAccount'
getTime: function () {
host="http://www.xxxxxx.com/";
res= Meteor.bindEnvironment(function(){
var Fiber = Meteor.require('fibers');
var Future = Meteor.require('fibers/future');
var future = new Future();
request(host, function (error, response, body) {
Fiber(function(){
if (!error && response.statusCode == 200) {
$ = cheerio.load(body);
var $thumbs = $('.thumb');
for (var i = 0, l = $thumbs.length ; i < l ; i++) {
// elements
var $thumb = $($thumbs[i]);
// save info
videourl=host+$thumb.find('a').attr('href');
videothumbs = [$thumb.find('img').attr('src')];
videos=Videos.insert({title:videoTitle,thumbs:videothumbs,lastUpdated:Date.now()});
}
return videos;
}
else {
return "error";
}
}).run()
});
}) ;
return res;
}
This is a server side method and returning undefined
Without bindenvironment it is returning error to use bindenvironemnt.
Am I using it properly, can somebody tell m the modifications in my code
You need a future to return the value of inner function:
Meteor.methods({
getTime: function() {
var future = new Future();
Meteor.bindEnvironment(function() {
future.return('Some value');
});
return future.wait();
},
});
Check out this Meteorpad for an example.
If you use suggestion from #saimeunt comment, then your code could be simplified into form:
SERVER:
Meteor.methods({
getSite:function(url){
var site = HTTP.get(url);
console.log("statusCode =\n " , site.statusCode);
console.log("content.length =\n ",site.content.length);
console.log("header =\n ",site.headers);
$ = cheerio.load(content);
...
}
})
CLIENT :
Meteor.call("getSite", "http://www.google.com");
See how it works
