json patch (jsonpatchdocument) rfc 6902 implementation for .net to easily allow & apply partial rest-ful service (through web api) updates from any client (portable class library). this component supports staticly typed objects. dynamically typed objects are supported as well: have a look at marvin.jsonpatch.dynamic (important: if you’re using asp.net core, you don’t need this component - i’ve been working with microsoft on integrating this into asp.net core. have a look at for more information, or have a look at for a more recent post on this. json patch (defines a json document structure for expressing a sequence of operations to apply to a javascript object notation (json) document; it is suitable for use with the http patch method. the "application/json-patch+json" media type is used to identify such patch documents. one of the things this can be used for is partial updates for rest-ful api’s, or, to quote the ietf: "this format is also potentially useful in other cases in which it is necessary to make partial updates to a json document or to a data structure that has similar constraints (i.e., they can be serialized as an object

QUESTION
Are there any recommendations for cases where you need some members to be immutable/read-only as far as patch operations are concerned?
Normally we would pass a context entity to the JsonPatchDocument, we expose the entire object to modification bar any entity validation rules you may have.
I can imagine a case were one member of an entity should not be editable for security reasons or may be a calculated value.
I don's see much online regarding this, one way I could think of was to map my entity to an UpdateRequest/DTO class that you could pass to initialize the JsonPatchDocument object. Then run the patch operation against that, finally mapping the updateRequest back to the db entity and persisting.
I think this would work, but feels a little messy, would be great to have a decorator that restricted patch operations on a per member basis e.g [NoPatch] or the inverse.
Here is a nice standard implementation of Dotnet API patch operation that matches my current understanding of the topic How to use JSONPatch in .net core

Answered 2022-Feb-19 at 14:47After more research I came across this project which allowed you to pass in a list of immutable members Tingle.AspNetCore.JsonPatch.NewtonsoftJson
I wanted to take that further and decorate my entities with attributes that could also handle role based permissions and have the ability to disable patch operations completely, so this is what I came up with.

QUESTION
I want to support partial updates with JSON Merge Patch. The domain model is based on the always valid concept and has no public setters. Therefore I can't just apply the changes to the class types. I need to translate the changes to the specific commands.
Since classes have nullable properties I need to be able to distinguish between properties set to null and not provided.
I'm aware of JSON Patch. I could use patch.JsonPatchDocument.Operations to go through the list of changes. JSON Patch is just verbose and more difficult for the client. JSON Patch requires to use Newtonsoft.Json (Microsoft states an option to change Startup.ConfigureServices to only use Newtonsoft.Json for JSON Patch (https://docs.microsoft.com/en-us/aspnet/core/web-api/jsonpatch?view=aspnetcore-6.0).
Newtonsoft supports IsSpecified-Properties that can be used as a solution for JSON Merge Patch in the DTO classes (How to make Json.NET set IsSpecified properties for properties with complex values?). This would solve the problem, but again requires Newtonsoft. System.Text.Json does not support this feature. There is an open issue for 2 years (https://github.com/dotnet/runtime/issues/40395), but nothing to expect.
There is a post that describes a solution with a custom JsonConverter for Web API (https://github.com/dotnet/runtime/issues/40395). Would this solution still be usable for NetCore?
I was wondering if there is an option to access the raw json or a json object inside the controller method after the DTO object was filled. Then I could manually check if a property was set. Web Api closes the stream, so I can't access the body anymore. It seems there are ways to change that behavior (https://gunnarpeipman.com/aspnet-core-request-body/#comments). It seems quite complicated and feels like a gun that is too big. I also don't understand what changes were made for NetCore 6.
I'm surpised that such a basic problem needs one to jump through so many loops. Is there an easy way to accomplish my goal with System.Text.Json and NetCore 6? Are there other options? Would using Newtonsoft have any other bad side effects?

QUESTION
I would like to allow for versioning of text in Vespa. If a user changes certain fields over time the changes would be tracked and versions could be restored.
I imagine a solution running in parallel to Vespa would be the way to go, with version numbers being stored in the vespa doc as unindexed data.
Any recommendations on a solution to use to do this? Something like http://jsonpatch.com?
...ANSWER
Answered 2022-Jan-23 at 16:00I would just store each version as a separate document by including the version in the document id.

I have Kubernetes cluster set up and managed by AKS, and I have access to it with the python client.
Thing is that when I'm trying to send patch scale request, I'm getting an error.
I've found information about scaling namespaced deployments from python client in the GitHub docs, but it was not clear what is the body needed in order to make the request work:
...ANSWER
Answered 2022-Jan-13 at 19:29The body argument to the patch_namespaced_deployment_scale can be a JSONPatch document, as @RakeshGupta shows in the comment, but it can also be a partial resource manifest. For example, this works:
QUESTION
I'm trying to deploy a django application on AWS EC2 for the first time. I'm using Ubuntu server, but it happens that the packages I installed are not recognized, the packeges have already been added to the INSTALLED_APPS. The error I'm getting is:
...ANSWER
Answered 2021-Sep-08 at 07:22The error occurred because you have installed your dependencies using Sudo.
This has installed your pip dependencies only for Sudo users, whilst you are running your Django application as a non-sudo user. This is the reason why you didn't saw your packages when you did pip freeze but you saw them after doing sudo pip3 freeze
To solve this
- Install
python3-venvwith this commandsudo apt-get install python3-venv - Create a virtual environment
python3 -m venv envthis command will create a virtual environment namedenv - Activate the virtual environment with this command
source env/bin/activate
Once you have done this you will see a (env) before your shell which indicates that your virtual environment is activated now need to install the dependencies inside this
cdto your requirements.txt and typepip3 install -r requirements.txtmake sure you do it without sudo (because you will run your Django app in your web server as a non-sudo privilege user for security reasons)
After this, you can run your Django app with your virtual environment kept active.
