You need to use the factory trait for the model to have the

What am I trying to do?
Django does not support setting enum data type in mysql database. Using below code, I tried to set enum data type.
_mysql.connection.query(self, query) django.db.utils.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'NOT NULL,
created_atdatetime(6) NOT NULL,
user_idbigint NOT NULL)' at line 1")
Am I missing anything?
Enumeration class with all choices...

You can print out the sql for that migration to see specifically whats wrong, but defining
db_type to return
"enum" is definitely not the right way to approach it.
I'm exploring a new DDD project using SQLAlchemy and Alembic for the first time. I'd like to use imperative mapping to isolate my domain objects. All the doc I can find about auto generating migrations with Alembic is using declarative mapping. Is it because I have to manually write all migrations if I want to use imperative mapping ?...

I am using MongoDB(Mongo Atlas) in my Django app. All was working fine till yesterday. But today, when I ran the server, it is showing me the following error on console...
ANSWERAnswered 2021-Oct-03 at 05:57
This is because of a root CA Let’s Encrypt uses (and Mongo Atals uses Let's Encrypt) has expired on 2020-09-30 - namely the "IdentTrust DST Root CA X3" one.
The fix is to manually install in the Windows certificate store the "ISRG Root X1" and "ISRG Root X2" root certificates, and the "Let’s Encrypt R3" intermediate one - link to their official site - https://letsencrypt.org/certificates/
Copy from the comments: download the .der field from the 1st category, download, double click and follow the wizard to install it.
I have an app with postgres as db, sequelize, and express, and whenever it receives a db query, it just stays there forever, no logging or anything I run postgres in a container which I can connect to through GUI normally When I swapped it for sqlite, it worked perfectly the application

I think it is your "0.0.0.0:5432".
If local, it should be just "localhost:5432". If deployed server is remote, it should be a certain IP address XXX.XXX.XXX.XXX:5432. If deployed server is home network, it should be "192.168.0.XXX:5432".
Check your postgres network configuration https://youtu.be/Erqp4C3Y3Ds

I've deleted two columns in two different tables. And I tried repeat the
@DeleteColumn annotation, like so

Kotlin has yet to add full support for repeatable annotations with the same syntax as Java. So we'll have to use the container annotation, like this:
I am trying to use the new DateOnly aspects of c# but when I come to do my migrations I am having the following issue. I am using SQL Server 2019 the error is.

ANSWERAnswered 2021-Sep-12 at 10:54
You have two choices:
use DateTime instead of DateOnly.
build a custom converter (see below).
As far I can see, the actual version of Entity Framework Core issue tracker states that model builder does not support it (find the issue here). Building a converter may solve your issue (cited from there):
I'm trying to build an API with EF Core as database access, right now on dotnet 6 RC1. I want to use dotnet cli tools to manage migrations (creating, updating the database etc), but the tools do not cooperate with minimal API from the template.

I created an MinimalAPI project using EFCore Context and it runs fine no major problem ocourred, other than updating ef tools cli and so on, see the complete project:

I want to reuse a variable in
Kustomize patches in our deployments. Specifically, we are using commit IDs to reference image tags (Use Case A) and k8s Jobs related to the deployments (Use Case B).
We use a setup where for each ArgoCD app we have a
/base/ folder and
/overlays/[environment-name], this base is patched with a
A very straightforward usage - in
/overlays/[environment-name] we have a
kustomization.yaml which uses:

but I want to reuse a variable within the manifests.
This is not how you typically work with Kustomize. Its a good thing that things are declarative and explicit when working with Kustomize.
when developers do PRs for releases, they should only touch one reference to the commit ID to prevent typos etc. (also easier to review instead of checking commit ID in N places)
yes and no.
That there is a change in four places should not be seen as a problem, in my opinion. That there is human toil to update four places is the problem.
The solution to human toil is typically automation. By using yq in an automated pipeline (e.g. Jenkins - or a shellscript) can you automate your manifest-update to take a single parameter - this can optionally be automated directly for each build after you have a git "commit id" available. The pipeline need to run four
yq-commands to update the four Yaml fields. See e.g. assign operation and github action - pipeline example. No other variables are needed.
I try to execute command
update-database in PMC and always get this error msg. I know theres another article basically has the same error but i tried every answer and nothing works.

Try updating EntityFramework package to the latest version. I was having the same problem with EF 6.1.3, but then updated to 6.4.4 and it worked fine on VS2022 preview.

PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
