DBProject | Simple database in C | Database library

I'm generating a migration and then applying it to a database but I'm getting a weird error about not having any files to deploy.

I'm trying to make an app with MERN stack. When I'm trying to add a user to the current database, it returns with CastError: Cast to ObjectId failed for value "undefined" at path "_id" for model "Project" What have I done wrong?

API.js

I'm making a simple edit operation for my Project model in a RazorPage. I can read the data and edit the data in the model but I'm unable to save it back into the database.

It's as if the public bound Project variable is suddenly no longer linked to the database-context anymore. In the OnPost(), the bound Project variable doesn't seem to be the same as the one from await _context.Project.FirstAsync(p => p.Id == project.Id); anymore?

Code:

Any time I try to run npm start I get an error saying:

npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! dbproject@0.1.0 start: set PORT=9999 && react-scripts start npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the dbproject@0.1.0 start script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

So far I've tried:
-Changing environment variables, my current environment variables are these
-Cleaning the npm cache, deleting the node_modules and then running npm install again
-I tried running npm start in different project folders, none of the React projects work, they all throw the same error. Node servers run well, I haven't tried running anything else.

I'm running Windows 10 Home Build 17134.

I would be extremely grateful of any help

I want to run my integration tests against a local Docker-hosted SQL Server 2019 database inside an Azure pipeline. I'm trying to copy over sqlpackage to this Docker image so I can restore a .bacpac each time in order to setup the database before the tests. Here's the YAML config I have so far:

azure-pipelines.yml:

I'm writing a Spring Boot application that starts up, gathers and converts millions of database entries into a new streamlined JSON format, and then sends them all to a GCP PubSub topic. I'm attempting to use Spring Batch for this, but I'm running into trouble implementing fault tolerance for my process. The database is rife with data quality issues, and sometimes my conversions to JSON will fail. When failures occur, I don't want the job to immediately quit, I want it to continue processing as many records as it can and, before completion, to report which exact records failed so that I, and or my team, can examine these problematic database entries.

To achieve this, I've attempted to use Spring Batch's SkipListener interface. But I'm also using an AsyncItemProcessor and an AsyncItemWriter in my process, and even though the exceptions are occurring during the processing, the SkipListener's onSkipInWrite() method is catching them - rather than the onSkipInProcess() method. And unfortunately, the onSkipInWrite() method doesn't have access to the original database entity, so I can't store its ID in my list of problematic DB entries.

Have I misconfigured something? Is there any other way to gain access to the objects from the reader that failed the processing step of an AsynItemProcessor?

Here's what I've tried...

I have a singleton Spring Component where I store how many DB entries I've successfully processed along with up to 20 problematic database entries.

I'm trying to build a system that allows users to make 'projects'. These projects have a fairly simple syntax, they just need an ID, a name, optionally a description and the participants.

Because I want users to be able to add or remove other users from the project without having to input the entire list of users again, I want to make use of a string or array or some such method instead of a string.

However, I'm stuck with trying to input it. I initially tried a regular list, but SQLalchemy didn't accept that. After a google search, it appears that's not possible? Unless I simply haven't come upon it.

I am now trying to use an Array instead. My current code looks like this:

I'm using EF core in a .net core project. After fetching data from ef context, the object's entity's (one-to-many etc...) are automatically loaded.

Here's my code:

I have made a webapp where you search by client id, and then adds orders on that client. The index action method assigns the chosen client to the viewmodel(vm.AllClients). The order table of course has information about the client. In the Insert method i want to use the information about the chosen client, but now vm.AllClients is returning null.

During debugging vm.AllClients is filled with one client object, as it should, during the running of the first method. When the second method is running vm.AllClients is empty.

I have tried to save the search string as a variable and find it in the db(Not a good solution), but the variable is also empty during the running of the second method. Also tried to save the chosen client as a Client object in the viewmodel, still no dice.
