Meteor Method to send a public MongoDB document without publishing everything - mongodb

new to meteor and mongo.
I have some JSON stored in mongo that I want to publicly expose via an obfuscated token without using something like:
//app/models/stuff.js
Stuff = new Mongo.Collection("stuff");
Meteor.publish("stuff", function (){
return Stuff.find();
});
//additionally, the client-side subscription
I only want to expose the files that the client directly requests via a URL routing parameter or some sort of client side identifier (like a textfield where you can type the code/token in)
e.g., http://website.com/view/abcdefghijklmnop
Anyone with knowledge of the link can type it in, and get the file. However, there should be no way to just get every file without being given every token.
I was wondering if this was the best way to accomplish the task:
//app/server/stuff.js
Meteor.methods({
getStuff: getStuff
});
function getStuff(stuffId) {
var result = Stuff.find({_id: stuffId});
return result;
}
then
//app/client/stuff.js
var json = Meteor.call('getStuff', 'abcdefghijklmnop');

Why not just publish the requested document?
Meteor.publish('stuff', function (id){
check(id, String);
return Stuff.find(id);
});

make meteor restful api/web-service

I have created a new url/route in my app where I need to write a web-service. I need to write a service that deletes user according to the parameters passed in the service. For now, anyone should be able to call that service (will make it secure at later stage). App is built on meteor.
My url is : loaclhost:3000/deleteUser. Now one should be able to call my delete user function defined on this page and pass json structure data as an argument to it. If the data is valid, then the user should be deleted.
Using simple:rest package
Meteor.publish("delUser", function (a, b) {
UserDetails.remove({}); //delete user according to data received
}, {
url: "/testing/delUser", //url where third party will call the function
getArgsFromRequest: function (request) {
// Let's say we want this function to accept a form-encoded request
// with fields named `a` and `b`.
console.log('received : ' + JSON.stringify(request.body) );
var content = request.body;
// Since form enconding doesn't distinguish numbers and strings, we need
// to parse it manually
return [content.a, content.b];
}
})
How to access the function, delUser from a thrid party? I also need to add authentication at a later stage.
Personnally, I use this :
simple:rest
simple:json-routes
simple:rest-accounts-password
I find it easier to implement.
even iron:router comes with server side routes where you can build your own functions and api calls.
http://iron-meteor.github.io/iron-router/#restful-routes
Sample (Server side code) :
Router.map(function () {
this.route("api", {path: "/api/:paramsYouNeed",
where: "server",
action: function(){
this.response.writeHead(200, {
'Content-Type': 'application/json',
'Access-Control-Allow-Origin': '*'
});
if (this.request.method == 'POST') {
var response;
//do whatever you want to do
this.response.end(response);
}
}
});
The other user can call this by making a http.post request to the above url (http:www.a****a.com/api/params)
The easiest way to do this is use the restivus package.
https://atmospherejs.com/nimble/restivus
Restivus makes building REST APIs in Meteor 0.9.0+ easier than ever
before! The package is inspired by RestStop2 and Collection API, and
is built on top of Simple JSON Routes to provide:
A simple interface for creating REST APIs
Easy setup of CRUD endpoints for Mongo Collections
User authentication via the API
Optional login and logout endpoints
Access to this.user in authenticated endpoints
Custom authentication if needed
Role permissions for limiting access to specific endpoints
Works alongside the alanning:roles package - Meteor's accepted role permission package

How to create a website with a searchbar to query a mongo database?

I have a large mongoDB database set up and am trying to create a website where a user can use a searchbar to query the database remotely and have the results posted on the site (strictly read-only).
I have experience with databases for data analysis, but have never created a website for querying results.
I'm don't have any experience with web development and don't know what platforms (PHP? node.js?) to use.
Thanks in advance.
There are the following steps to the problem:
Create the front-end, which will consist of HTML, CSS, and Javascript. Beginners often find it easiest to work with jQuery and jQuery UI, because they are well-documented and contain plugins for almost all possible scenarios (they should not, however, be used to create large complex applications!). Bootstrap or Foundation can help you with the HTML / CSS.
Create a (probably) JSON API, which the front-end can communicate with to submit searches and retrieve results. You could use PHP, Python, Ruby, or many other languages to do this. For a simple site like the one you're describing, it's more a matter of preference than anything else.
Translate the search request from the front-end into the MongoDB query APIs, and return the results through the API. You will use a MongoDB client library compatible with whatever language you have chosen.
Depending on your needs, you may be able to eliminate (2) by using an existing REST API for MongoDB.
Note that if you just want to make MongoDB data accessible via searching / charting, then you may be able to avoid coding altogether by leveraging SlamData, an open source project I contribute to. SlamData lets you use Google-style search (or more advanced SQL) to query MongoDB and get the results back in tabular or chart form.
I am doing such in nodejs.
In my server side app I have connection via mognoose like:
var mongoose = require('mongoose');
mongoose.connect('mongodb://yourhost/database');
Next you need to have your model to your database
var YourDBVarName = mongoose.model('collectionName', {
yourfields1 : type,
yourfields2 : type,
yourfields3 : type
...
});
Then I make GET for it
var express = require('express');
var app = express();
app.get('/dblisting', function(req,res){
YourDBVarName.find({ yourfieldsX: 'value'}, function(err, data) {
if(err) {
res.send(err.message);
}
else{
res.send(data);
});
});
Then simply you make some GET with $.ajax to yournodeserver.com/dblisting and in response you recive your collection filtered as in
{ yourfieldsX: 'value'}
Ofcourse you may do just {} so you get all your stored data.

If you want know about retrieving data from mongoDB, you can use my github https://github.com/parthaindia/CustomMongo .Use getByCondition() method which requires collection name and a Map . The Map can be your queries in form of key value pair,Key being the column name. I use this method when I write search Query for the web development. The java code gives you a Json. Write a Servlet to post your Json to WEB UI.
This is an example to show how to post the retrieved data using Js ,"server_base_url + /server/FetchData" would be your Service URL.The data you has to be appended to a table . Or a span ,depends on what you actually want.The below code appends data
function getdata() {
$.get(server_base_url + "/server/FetchData", {
}).done(function (data) {
$.each(data, function (index, value) {
alert("The Index" + index + "The Value" + value);
$("#11table1").append("<tr><td id='dynamicid1" + index + "'>" + value + "</td></tr>");
});
});
}
This function can be used for defining table
function defineTable() {
$("#mainDivID").text("").append("<div id='contpanel' class='contentpanel'>");
$("#contpanel").append("<div id='rowid11' class='row'>");
$("#rowid11").text("").append("<div id='row11table1' class='col-md-12'>");
$("#row11table1").text("").append('<br /><br /><center><h5 class="lg-title mb5" style="background-color:#428BCA;height:20px;color:#fff;padding-top:4px;"><b>Heading</b></h5></center>');
$("#row11table1").append("<div id='table11id1' class='table-responsive'>");
$("#table11id1").append("<table id='11table1' class='table table table-bordered mb30' >");
$("#11table1").append("<thead><tr><th>Index</th><th>Value</th></tr></thead>");
}

Ember-cli , how do i change rest call on fly in the rest adapter

Im working on ember-cli, how do i change rest call on fly in the rest adapter. If i use path params not query params?for example:
export default DS.RESTAdapter.extend({
namespace:'res/v1/users/id',
pathForType: function() {
return Ember.String.underscore("friends");},});
Based on the user selection from dropdown we get the "id", using the id I need to get user friends from the database.
Could you please suggest a better way to do. My aapplication supports pathparams not the query params
To customize the URL, override the buildURL method in your adapter.
The tricky part is to access related records from the adapter. For example, you request friends for a given user. You work in a friend adapter, but you need to know the user's id to include it in the URL.
For that purpose, use the record property on the snapshot argument of the buildURL method.
Alternatively, you might want to override some of buildURL's underlying methods such as urlForFindQuery, depending on how you request your model from the store. With a find.query(), you will retrieve the id of the user from the query.
If this does not help you, please respond with the way you're trying to fetch friends from the store.
I have created a variable in enviroment.js 'userId'. When ever i select a user
i set config.userId in the controller to the corresponding Id.
config.userId=this.get('selectedUser');
In pathforType of adapter I used this varible
pathForType: function() {
return Ember.String.underscore(config.userId+"/friends");
}
you just need to add an import statement
import config from '../config/environment';
Please suggest me if anyone get to know better way. Thanks all for your responses
buildURL() only takes the type imo. so you have to pass some more jazz.
i did something along the lines of the following in the application adapter
$ ember generate adapter application
app/adapters/application.js
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
findQuery: function(store, type, query) {
var urlQuery = query.theshityouwant;
var reply = this.ajax(this.buildURL(type.typeKey + '/' + urlQuery), 'GET', { headers: all});
return reply;
},
})
});

publishing user relevant data

I have created a simple, minimalistic diary app.
On the client, I use
Meteor.subscribe('entries', Meteor.userId());
to subscribe to the entries created by the user (stored in a mongodb collection). I pass the users ID to the publish function (on the server):
Meteor.publish('entries', function(userID) {
return Entries.find({userId: userID});
});
After login, Meteor.userId() isn't falsy anymore, because it's a reactive data source. However, the relevant data is not being published. I fixed that by auto-running the subscribe function:
Tracker.autorun(function() {
Meteor.subscribe('entries', Meteor.userId());
});
It works, but I feel it's a bad solution.
So here comes the question:
How should one publish user-relevant data in general? There must be a better way to do this, than passing the users ID to the publish-function. Also, isn't it insecure?
By the way, would love to hear some feedback on the app
You don't need to pass the userId from the subscription. Inside the publish function you can use this.userId to get the current user. You can also just return an empty array if the user is not logged in.
Meteor.publish("entries", function () {
if (!this.userId) return [];
return Entries.find({ userId: this.userId });
});

Ember Data not storing ID

I'm working on a website using nodejs for server side, emberjs for client side and mongodb for database. I have a page where a user profile is created and saved but the id of the data is stored as undefined unless I refresh. Is there a way atound this?
I would have to see the specific code in order to answer this with certain, but I suspect that you're either not waiting for a response from the server, or you're not passing in the model when you transition to the new route. Ember-data automatically updates when it gets a response from the server.
The general flow should go like this:
Send your post request to the server.
The server creates the user in Mongodb, and when it gets that object back, it sends it back to the client.
On the client, you wait to get the user back from the server, and pass the model into your transitionTo helper.
Here's an example on the Ember side:
App.UserCreateController = Ember.ObjectController.extend({
actions: {
createUser: function() {
var self = this;
this.get('model')
.save()
.then(function() {
self.transitionToRoute('profile', self.get('model'));
}, function() {
alert('User not successfully saved');
});
}
}
});
Another possible issue is that you're not sending the data back as Ember-data expects. i.e. Your payload should look something like this:
{
user: {
_id: 'lkj234l23jlk5j4l32j5lk34',
name: 'Jon Snow'
}
}
And you should let Ember know that it should be using the _id instead:
App.ApplicationSerializer = DS.RESTSerializer.extend({
primaryKey: "_id"
});
If this isn't your problem, post some code or give more details.
