QUESTION
I used the database first approach. The model is right (or at least it looks like) But I always get this error. Please, I've already tried so many things.. The full code of my program (and even sql script by which I create my database) is here: https://github.com/AntonioParroni/test-task-for-backend-stack/blob/main/Server/Models/ApplicationContext.cs
Since I have a mac. I created my model with dotnet ef cli commands (dbcontext scaffold) I can use my context. But I can't touch any DbSet..
...ANSWER
Answered 2022-Mar-31 at 09:23You have net6.0 target framework which is still not released while you have installed EF6 which is a previous iteration Entity Framework (mainly used with legacy .NET Framework projects) and you also have EF Core (a modern iteration of it) but older version - 5.0 (which you are actually using for your context, see the using Microsoft.EntityFrameworkCore; statements there).
Try removing EntityFramework package and installing preview version of Microsoft.EntityFrameworkCore.SqlServer (possibly just updating to the latest 5 version also can help) and either removing completely or installing preview version of Microsoft.EntityFrameworkCore.Design. (Also I would recommend to update your SDK to rc and install rc versions of packages).
Or try removing the reference to EntityFramework (not Core one) and changing target framework to net5.0 (if you have it installed on your machine).
As for why do you see this exception - I would guess it is related to new methods added to Queryable in .NET 6 which made one of this checks to fail.
TL;DR
As mentioned in the comments - update EF Core to the corresponding latest version (worked for 5.0 and 3.1) or update to .NET 6.0 and EF Core 6.

I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs
...ANSWER
Answered 2022-Mar-16 at 07:01First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".
January 11, 2022 Final brownout.
This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.
Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.
As noted by Jörg W Mittag:
For GitHub Actions:There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".
Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.
The permanent shutdown is not until March 15th.
As in actions/checkout issue 14, you can add as a first step:
QUESTION
I am working on a spatial search case for spheres in which I want to find connected spheres. For this aim, I searched around each sphere for spheres that centers are in a (maximum sphere diameter) distance from the searching sphere’s center. At first, I tried to use scipy related methods to do so, but scipy method takes longer times comparing to equivalent numpy method. For scipy, I have determined the number of K-nearest spheres firstly and then find them by cKDTree.query, which lead to more time consumption. However, it is slower than numpy method even by omitting the first step with a constant value (it is not good to omit the first step in this case). It is contrary to my expectations about scipy spatial searching speed. So, I tried to use some list-loops instead some numpy lines for speeding up using numba prange. Numba run the code a little faster, but I believe that this code can be optimized for better performances, perhaps by vectorization, using other alternative numpy modules or using numba in another way. I have used iteration on all spheres due to prevent probable memory leaks and …, where number of spheres are high.

QUESTION
I want to apply pagination on a table with huge data. All I want to know a better option than using OFFSET in SQL Server.
Here is my simple query:
...ANSWER
Answered 2022-Jan-30 at 12:24You can use Keyset Pagination for this. It's far more efficient than using Rowset Pagination (paging by row number).
In Rowset Pagination, all previous rows must be read, before being able to read the next page. Whereas in Keyset Pagination, the server can jump immediately to the correct place in the index, so no extra rows are read that do not need to be.
In this type of pagination, you cannot jump to a specific page number. You jump to a specific key and read from there. For this to perform well, you need to have a unique index on that key, which includes any other columns you need to query.
One big benefit, apart from the obvious efficiency gain, is avoiding the "missing row" problem when paginating, caused by rows being removed from previously read pages. This does not happen when paginating by key, because the key does not change.
Here is an example:
Let us assume you have a table called TableName with an index on Id, and you want to start at the latest Id value and work backwards.
You begin with:

QUESTION
Upgrading kotlin to 1.6.0 causes Room Dao suspend modifier to break build project with error: "Not sure how to handle query method's return type........".
Are there(here) any solutions other than a workaround for running Dao functions withContext(Disapatchers.IO) in repository?
...ANSWER
Answered 2022-Jan-06 at 18:35I faced the same issue yesterday with the upgrade of Kotlin 1.6.0.
My working project started to fail, same error messages.
After searching in some other forums someone mentioned to change roomVersion to "2.4.0-beta02". And.. surprisingly it worked! At least it compiled without any more issues.
Try it , hopefully it will work for you too.
Mine is defined in a variable:
def roomVersion = "2.4.0-beta02"
So the rest of the dependencies for Room should take advantage of this change.
