does anyone know if it is possible to create relationships in the dashboard of parse?
I'm running the bitnami parse api 1.0.18 through aws ec2 and can't see anyway of doing it and the documentations only says you can do it through code. i want to have these set up in the background as the user won't write to them, probably just download some data and images.
i could just go and create a whole heap of tables with unique identifiers but this seems a bit of a dumb work around.
I strongly suggest you look into Cloud code. This is one of the reason why cloud code works so well! Simple to setup and little bit of javascript you'll be on your way.

If its something that needs to happen before the insert, look at the beforeSave method.

We are currently working with a Neo4j database, and we need some kind of id to identify nodes.
For example we have functions like CurrentUserHasAccess(NodeId)
On other Stackoverflow posts I read that it's a bad idea to use the internal neo4j-identifier, because it can change over time. However I think that's not an issue when we do not use this id to link data.
However I cannot seem to find any official sources about this topic.
I would like to use this ID because then we do not need to worry about uniqueness, and more importantly indexing.
You are right that it is generally not recommended to use the internal Neo4j node IDs. This is mainly because if a node gets deleted, its original internal ID may get recycled/reused. If you're looking for a quick and elegant solution to this, have a look at the UUID module of the GraphAware Framework here https://github.com/graphaware/neo4j-uuid and let us know if it works for you.
I would like use CloudKit without CloudKit Dashboard.
Could I have diffulculties or other during my development?

There are a couple of things that you can only do from the dashboard. You can use your app to create recordTypes with fields, but if you want to index fields and make them queryable, then you need to do that from the dashboard. You also need the dashboard to migrate your data structure to production.
What are you trying to do? This is like asking if you can develop an app with Xcode, but not use the debugger. It's possible, but why would you want to avoid a tool that helps make your job easier?
CloudKit was designed so that you could start writing code and using the database right away without needing to configure anything in the dashboard. However, at some point you're going to need to move to production or tweak the schema in your container and you're going to need the dashboard for that.
I took a look at Serilog.Sinks.EventLog at Github and noticed there doesn't seem to be a way to set the Event ID of the logged event (example IDs here).
Would there exist a way to modify the sink so that it'd be possible? Perhaps with some kind of specially formatted message? I don't know if I should put this here or on Github, I'll try here first. :)
There isn't a mechanism currently for this - designing one seems tricky (but ultimately it'd be a great addition to the project!)
I would like to sync a core data app with a user with a different iCloud ID and I am trying to figure out the most graceful way to do this. I do not want the data to sync with all users, but want to be able to sync among family members for instance. From the research I have done, I do not think I can do that using iCloud Core Data sync because it only syncs between devices with the same iCloud ID. I have looked at this stackoverflow answer and read a little bit about Ensembles, Parcelkit and TICoreDataSync, Parse etc., but it is not clear to me if any of those options will allow me to sync with multiple users. Does anyone have a good method for syncing a Core Data app with multiple users?
Ensembles and TiCoreDataSync might work. They can use Dropbox file syncing, so in principle they should work with Dropbox shared folders. I don't think these are the main intended uses, so I suggest contacting the developers and/or doing some good testing yourself before assuming this would actually work.
You'll need to think about the user experience, though. At a minimum, your users would both need Dropbox accounts and would have to set up a shared folder before beginning to sync data this way.
Parcelkit probably won't work. It uses Dropbox's data store API which, unlike other Dropbox services, doesn't appear to support shared data.
Services that do support this kind of sharing exist-- for example, Parse and Firebase-- but make sure to review their pricing carefully before using them. Also of course, there have been any number of projects that have their own custom server back end, but that obviously requires having someone on the team who can do that kind of work.
You need to think about other device types (Android at least) if you want your application to be reaching more users.
I'm doing the same now by the following way:
Setup an online database with proper web services (careful with implementation for security matters - DB should NEVER be exposed by anything other than the web services).
Create a Class for your communication with the server (using Class methods with security handling like authentication and authorisation).
Use the class in your app to communicate with the server (SQL operations are done on the server).
To integrate with CoreData you need to create the model in your app similar to the structure in the backend database. Then you need to create a similar class for the app that deals with only local CoreData.
A higher level class might be required if you want to make sure that operations done on both server and local data storage.
Besides, you have to implement a lot of conditions to make sure that data written in local ONLY after making sure that it is stored online (or create an engine for differed operations to run later).
Another Way if you are familiar with notifications:
Use structured notifications between devices for data operations in order to keep everything in sync with other users. The problem with this is the "Autonomy" of the operations. If two operations were done in approximately the same time, you have to find a way to make sure the order of the operations is done properly (maybe timestamp or something).
I'm looking into the same thing for my app and I 'think' you can do a fairly unsecured version of what you are after using using the public folder in cloud kit as mentioned in this question (no accepted answer at time of posting) : Private data sharing using CloudKit
You would need to find a way to differentiate between data that is truly public and those shared among the users you need and some level of authentication.
I'm going to try exporting a permission file with access permission in it to whomever I want to share with combined with a unique identifier located in that permission file.
Keep in mind, as mentioned in the comments of the linked answer, my implementation will be security by obscurity (thanks for that phrase) unless you find a way of adding proper validation to it but my data is relatively insensitive.
Hope this, or any ridicule in the comments, points you in the right direction : )
I was wondering how I would go about updating my passes. I already know I need a webServiceURL (which I assume will be your IP address or one set on Ruby on Rails or something) and an authentication token. I'm more focused on how I would actually, physically update it. Is there an easy way out of this? Sort of like those iPhone app creating websites (but you don't professionally code it). I'm going to look into it more, but there aren't too many resources on the internet to choose from (that are useful).
If you are looking for a WYSIWYG, point and click solution, you might want to check out our service PassKit.
To see how updates work, you can start with this demo pass, flip it over and push yourself an update. You can import the template for the demo direct into the pass creator, edit it, and be pushing updates to your own passes within 5 minutes.
We also have a fully functional API that allows your to update and push a new pass your pass in a single call, E.g.
https://api.passkit.com/v1/pass/update/template/yourTemplateName/serial/yourPassSerial/push/?field_value1=newValue&field_value2=newValue2
If you want some code to get you stated, you can also access the source code to our pass creation pages.
If you are going to roll your own, I would use passbook-ios or something like that which is a Ruby Gem. If you want to use a service Urban Airship has one....though the pricing is a bit expensive at 10 cents a pass.
