I want to extend my api using loopback . I have read the documentation
'use strict';
module.exports = function(Meetups,pusher) {
Meetups.status = function(cb) {
var currentDate = new Date();
var currentHour = currentDate.getHours();
var OPEN_HOUR = 6;
var CLOSE_HOUR = 20;
console.log('Current hour is %d', currentHour);
var response;
if (currentHour >= OPEN_HOUR && currentHour < CLOSE_HOUR) {
response = 'We are open yeah!!! for business.';
} else {
response = 'Sorry, we are closed. Open daily from 6am to 8pm.';
}
cb(null, response);
};
Meetups.remoteMethod(
'status', {
http: {
path: '/status',
verb: 'get'
},
returns: {
arg: 'status',
type: 'string'
}
}
);
Meetups.pusher = function(cb) {
if (2>1) {
response = 'sending something';
} else {
response = 'mont blanc';
}
cb(null, response);
};
Meetups.remoteMethod(
'pusher', {
http: {
path: '/pusher',
verb: 'get'
},
returns: {
arg: 'pusher',
type: 'string'
}
}
);
};
First, I added /status route and it worked fine. But, when i tried to add /pusher . It just didnt work. I am getting an error
{

}
I am pretty sure, its a very small mistake. I am beginner in loopback and trying to implement loopback in my project.
In the example they define response as a local variable to that remote method, you did not. Secondly, (Meetups,pusher) you do not need to export pusher here. You are adding to Meetups.
You have to declare response in your pusher remote method.
An alternative way without declaring response is, Simply returning the value.
Example:
Meetups.pusher = function(cb) {
if (2>1) {
return 'sending something';
} else {
return 'mont blanc';
}
};
Define the variable and return the variable or you can directly call the cb in if and else like
Meetups.pusher = function(cb) {
if (2>1) {
cb(null,'sending something');
} else {
cb(null, 'mont blanc');
}
};

On button click I have programmed to call a graphql api which is connected to a Lambda function and the function is pulling data from a dynamodb table. The query does not produce any error, but it doesn't give me any results as well. I have also checked the cloudwatch logs and I dont see any traces of the function being called. Not sure on the careless mistake I am making here.
Here is my api
void findUser() async {
try {
String graphQLDocument = '''query getUserById(\$userId: ID!) {
getUserById(userId: \$id) {
id
name
}
}''';
var operation = Amplify.API.query(
request: GraphQLRequest<String>(
document: graphQLDocument,
variables: {'id': 'USER-14160000000'}));
var response = await operation.response;
var data = response.data;
print('Query result: ' + data);
} on ApiException catch (e) {
print('Query failed: $e');
}
}
Here is my lambda function -
const getUserById = require('./user-queries/getUserById');
exports.handler = async (event) => {
var userId = event.arguments.userId;
var name = event.arguments.name;
var avatarUrl = event.arguments.avatarUrl;
//console.log('Received Event - ', JSON.stringify(event,3));
console.log(userId);
switch(event.info.fieldName) {
case "getUserById":
return getUserById(userId);
}
};
const AWS = require('aws-sdk');
const docClient = new AWS.DynamoDB.DocumentClient({region: 'ca-central-1'});
async function getUserById(userId) {
const params = {
TableName:"Bol-Table",
KeyConditionExpression: 'pk = :hashKey and sk = :sortKey',
ExpressionAttributeValues: {
':hashKey': userId,
':sortKey': 'USER'
}
};
try {
const Item = await docClient.query(params).promise();
console.log(Item);
return {
id: Item.Items[0].pk,
name: Item.Items[0].details.displayName,
avatarUrl: Item.Items[0].details.avatarUrl,
createdAt: Item.Items[0].details.createdAt,
updatedAt: Item.Items[0].details.updatedAt
};
} catch(err) {
console.log("BOL Error: ", err);
}
}
module.exports = getUserById;
Upon button click I get this
Moving my comment to an answer:
Can you try changing your graphQLDocumnet to
String graphQLDocument = '''query getUserById(\$id: ID!) {
getUserById(userId: \$id) {
id
name
}
}''';
Your variable is $userId and then $id. Try calling it $id in both places like in your variables object.
Your flutter code is working fine but in lambda from the aws is returning blank string "" to not to print anything
I'm trying to load test an API (GET method) using loadimpact k6 which requires oauth token for authorization to get the successful response. I already have a postman collection file which does this by running pre-request script. The pre-request script will request token from the authorization server and then populates the token in the environment variable. I used the "Postman to LoadImpact converter" to generate the k6 script but it isn't doing any help. The script fails to get the access token.
The generated script from the converter is given below:
// Auto-generated by the Load Impact converter
import "./libs/shim/core.js";
export let options = { maxRedirects: 4 };
const Request = Symbol.for("request");
postman[Symbol.for("initial")]({
options,
collection: {
currentAccessToken: "",
"Client-Id": "",
"Client-Secret": "",
"Token-Scope": "",
"Grant-Type": "client_credentials",
"Access-Token-URL": "",
accessTokenExpiry: ""
}
});
export default function() {
postman[Request]({
name: "Collection Mock",
id: "",
method: "GET",
address:
"",
headers: {
Authorization: "Bearer {{currentAccessToken}}"
},
pre() {
const echoPostRequest = {
url: pm.environment.get("Access-Token-URL"),
method: "POST",
header: "Content-Type:x-www-form-urlencoded",
body: {
mode: "urlencoded",
urlencoded: [
{ key: "client_id", value: pm.environment.get("Client-Id") },
{
key: "client_secret",
value: pm.environment.get("Client-Secret")
},
{ key: "grant_type", value: pm.environment.get("Grant-Type") },
{ key: "scope", value: pm.environment.get("Token-Scope") }
]
}
};
var getToken = true;
if (
!pm.environment.get("accessTokenExpiry") ||
!pm.environment.get("currentAccessToken")
) {
console.log("Token or expiry date are missing");
} else if (
pm.environment.get("accessTokenExpiry") <= new Date().getTime()
) {
console.log("Token is expired");
} else {
getToken = false;
console.log("Token and expiry date are all good");
}
if (getToken === true) {
pm.sendRequest(echoPostRequest, function(err, res) {
console.log(err ? err : res.json());
if (err === null) {
console.log("Saving the token and expiry date");
var responseJson = res.json();
pm.environment.set("currentAccessToken", responseJson.access_token);
var expiryDate = new Date();
expiryDate.setSeconds(
expiryDate.getSeconds() + responseJson.expires_in
);
pm.environment.set("accessTokenExpiry", expiryDate.getTime());
}
});
}
}
});
}
The issue is with pm.sendRequest which is not supported by the converter and I'm not sure what the alternative is. So, I'm looking for ways to dynamically request access token from the authorization server and use that token to make a request to the API for load testing in k6 script.
As you have seen sendRequest is not supported ...
This is primarily because of the fact pm.sendRequest is asynchronous but k6 at this point doesn't have a event loop so ... no asynchronous http calls :( (except with http.batch but ... not
I find it unlikely that you want this to be asynchronous or ... well you can't do it with k6 at this point either way ... you can just rewrite it to use k6's http.post
As far as I can see this should look like
pre() {
var getToken = true;
if (
!pm.environment.get("accessTokenExpiry") ||
!pm.environment.get("currentAccessToken")
) {
console.log("Token or expiry date are missing");
} else if (
pm.environment.get("accessTokenExpiry") <= new Date().getTime()
) {
console.log("Token is expired");
} else {
getToken = false;
console.log("Token and expiry date are all good");
}
if (getToken === true) {
let res = http.post(pm.environment.get("Access-Token-URL"), {
"client_id": pm.environment.get("Client-Id") ,
"client_secret": pm.environment.get("Client-Secret"),
"grant_type": pm.environment.get("Grant-Type"),
"scope": pm.environment.get("Token-Scope")
});
console.log(err ? err : res.json());
if (err === null) {
console.log("Saving the token and expiry date");
var responseJson = res.json();
pm.environment.set("currentAccessToken", responseJson.access_token);
var expiryDate = new Date();
expiryDate.setSeconds(
expiryDate.getSeconds() + responseJson.expires_in
);
pm.environment.set("accessTokenExpiry", expiryDate.getTime());
}
}
Disclaimer: I have never used postman and the code above was written/copy-pasted by hand and not tested :)
I ended up using below code snippet to make a successful call for my purpose:
// Auto-generated by the Load Impact converter
import "./libs/shim/core.js";
import http from "k6/http";
import { check, sleep } from "k6";
export let options = {

}

pm.environment.set("accessTokenExpiry", "");
pm.environment.set("clientId", "");
pm.environment.set("clientSecret", "");
pm.environment.set("tokenScope", "");
pm.environment.set("grantType", "");

export default function() {
var getToken = true;

} else {
getToken = false;
//console.log("Token and expiry date are all good");
}
if (getToken === true) {
//get the access token first

var checkRes = check(res, {

if (checkRes) {

pm.environment.set("currentAccessToken", responseJson.access_token);
var expiryDate = new Date();
expiryDate.setSeconds(
expiryDate.getSeconds() + responseJson.expires_in

sleep(1);
//make the api request using the access token and subscription keys (if required)
let apiRes = http.get(pm.environment.get("apiUrl"),
{

}
});
check(apiRes, {

In Vtiger 6.5.0 open source, I wants to create a alert function to warn users that the conact's mobile is existing? could you please help me. I'm fresher.
Thanks,

You can refer the function wich exist in Account module for checking Duplicate Account Name.
Please follow this files you will get an idea.
This is the code flow how its done In Account Module
Registring Pre Save Event
http://code.vtiger.com/vtiger/vtigercrm/blob/master/layouts/vlayout/modules/Accounts/resources/Edit.js#L250
This teh Fucntion to check Duplicate in cache, If not calls the Helper function
http://code.vtiger.com/vtiger/vtigercrm/blob/master/layouts/vlayout/modules/Accounts/resources/Edit.js#L83
This the Helper function which makes the call to server
http://code.vtiger.com/vtiger/vtigercrm/blob/master/resources/helper.js#L166
This is the action function which is responsible for Serving the request which came from Helper Function
http://code.vtiger.com/vtiger/vtigercrm/blob/master/modules/Accounts/actions/CheckDuplicate.php#L30
And this is the function which checks for Duplicate
http://code.vtiger.com/vtiger/vtigercrm/blob/master/modules/Accounts/models/Record.php#L57
Hope this helps.
Hi Victor please follow this steps

2: Create new file in** \modules\Contacts\actions\CheckDuplicate.php
Follow the same process / code as given in \modules\Accounts\actions\CheckDuplicate.php
3: Add new function checkDuplicate() in \modules\Contacts\models\Record.php
And follow same process as given in \modules\Accounts\models\Record.php having function checkDuplicate()
Note: Don't forget to change the db table name, class name module wise.
Hope this will help you. Thank you.
I can't seem to fetch new data in Internet Explorer 9. For the purpose of an example I test the store this way:
App.__container__.lookup('store:main').find('style')
The only error I receive is the following:
SCRIPT5022: Error: Assertion Failed: [object Object]
Does Ember-data works out of the box (without polyfills, ...) in Internet Explorer 9?
versions:
Ember: 1.9.1
Ember-data: 1.0.0-beta.12
Problem solved. When doing an AJAX request with jQuery, this normally happens through the XMLHttpRequest object.
On IE8-9, this object is not present, instead it uses XDomainRequest. The simplest fix for this is adding: https://github.com/MoonScript/jQuery-ajaxTransport-XDomainRequest.
ember-data works out of the box with IE8+. According to this issue:
We've been supporting IE8 with our platform (built on Ember) for a
while now. Things I know:
shim/sham is not needed, it's polyfilled by Ember and Ember-Data.
You will need it if you want additional things like .bind() on a function, then you must prepend it to the vendor file (using Brocfile)
and we only include the shim for that purpose, not the sham
Solution Synthesis
Reason :
On IE8-9, this object is not present, instead it uses XDomainRequest.
Solution :
The issue is solved. When using an AJAX request with jQuery. Normally this is done through the XMLHttpRequest object. A simple fix would be using the Open-Source jQuery-ajaxTransport-XDomainRequest

What i'm doing is loading Ids from my Parse database and for each Id I want to call a httpRequest to Facebook Api. The problem is that httpRequest seems to not work when there is not a response.success (it ends the proccess) call inside itself.
This is what I have so far:
Parse.Cloud.define("hello", function(request, response) {
var query = new Parse.Query("Location");
query.find({
success: function(results) {
console.log(results);
for (var i = 0; i < results.length; ++i)
var locationId = results[i].get("locationId");
console.log(locationId);
Parse.Cloud.httpRequest({
url: 'https://graph.facebook.com/v2.2/'+locationId+'/events?access_token='+accessToken,
success: function(httpResponse) {
console.log(httpResponse.data);
response.success("result");
},
error:function(httpResponse){
console.error(httpResponse.message);
response.error("Failed to login");
}
});
...
Any ideas?
I'm not the most up on my javascript, but I'm pretty sure this is the concept you're looking for. It's possible better solutions exist.
var totalResults = results.length;
var completedResults = 0;
var completion = function() {
// Because you're doing multiple requests, you'll need to figure out how you determine success/failure. ie: Are any failures considered an overall failure? Do you want to pass a more detailed success?
response.success("Finished");
};
