I am using PouchDB 5.3 with Couchbase Sync Gateway 1.2, with the sync function. If I login using a user that has access to 2500 documents, it sync them to my device, but, if I logout and login with the other user, that has access to only 1 document, PouchDB doesn´t recognize this change, and keep data on my device.
If PouchDB is able to sync changes on both sides, should be able to recognize when the user change?
It seems it doesn´t support this functionality.

We have a Firebase database connected with an APP which we want to convert to a website now. Laravel is nice frame work but unfortunately unable to sync the existing database to show up on the website as is. End goal is that any changes through an APP should reflect on the website and vice versa. Existing database include the product price, picture, ability for users to message each other , user authentication. In essence it is almost a complete market place.
If you want to use data from the Firebase Realtime Database in a web app/site, consider simply using its JavaScript SDK in your web application.
Doing so allows you app to directly read data from the database, instead of having to set up a web server in Laravel.
To ensure that your users only get access to data they're authorized for, you'll want to use Firebase's security rules. These are enforced on the Firebase server, so once you configure them correctly, there's no way for anyone to bypass them.
Does anyone has any experience in next task:
I have ready project with some functionallity (some CRUD and payment functions)
I need to make something like demo mode. Where user can create records and make payments (always successfull, without taking charge), but it should not be recorded to database.
All entered data should be available only for this user and be live only fo
My question is how to make it without making copy of the controllers for fake actions?
I have try to look in to database driver that works with session as storage but have not found anything about it.
Initially I would like to inform you that I am using ember 2.10.
Can anyone tell me how to make a login system without a token?
I am developing an offline application with Ember and Electron and I need to make the login system without using external APIs.
If I understand you right, you want to create an application that will support few users. It is possible. You will need to perform following steps:
Install ember-simple-auth plugin. It makes auth-related things much easier
Create custom authenticator that will take a login and password or something from your users and save some identifier in session
Create login and register routes, where users will be able to login or create new credentials
Most probably you will not need an authorizer, because you don't have server api and don't send requests to it
Bear in mind that this will be zero-security system, even if you will use some encryption, because js code is not secured well from exploration. Also bear in mind that electron most probably stores user's data in user's home directory (I can't say for sure as I didn't work with electron, but node-webkit does that). In this case having different windows (or what OS your users will use) users is enough to separate data and you actually don't need any login system.
I recently noticed the addition of a "Session" object in Parse dashboard. Now, from what I understand, a session uniquely identifies a user to the server. So why would we need such a Session? For the session token? We already have a currentInstallation... so I don't really see the point. Can someone explain and provide a scenario where I would use the "Session" object. Right now they just annoy me by their presence because they take up potential space on the Parse server and I would like to go delete them all but want to make sure that isn't stupid.
The sessions are used by parse to deal with the users (is the user logged?, on which devices?, etc.), and are available as a class as you may want to manipulate them. By deleting the sessions you would automatically logout all your users, so it's a pretty bad idea.
You don't have to use or touch anything about this class, but here are few examples of why it can be useful:
[...] If a user contacts you about his or her account being compromised in your app, you can use the Data Browser, REST API, or Cloud Code to forcefully revoke user sessions using the Master Key. These new APIs also allow you build a “session manager” UI screen where your app’s users can see a list of all devices they’ve logged in with, and optionally log out of other devices. [...]
You can read more about the Sessions on their blog post.
I'm writing an app that's supposed to run with MVC5 and using parse as a backend.
I'm using the new Identity feature of the MVC5 to login an user. I also tried to use this solution but I couldn't make it work.
What is happening is that when I login with the user A and then login with the user B in a different session (a incognito windows or a new browser) whenever I try to insert something related with a ParseUser object using the first user that was logged in I get an exception: UserCannotBeAlteredWithoutSessionError.
I'm not sure if I'm doing the implementation in a wrong way, or if it is a limitation of the Parse (I think it was designed to run using one user per device).
If you have a workaround for this situation please help me.
There is a good answer which may help: Parse Database Authorization - Security For User Objects.
So, it's a kind of Parse SDK limitation, when you can work with only one user per device (as ParseUser is cached locally). The only workaround that I can see is to perform SignOut/Login explicitly, when you need to do something from other user's context. There is no way to have two users work simultaneously from the same device.
