kandi X-RAY | db_type Summary
Many databases (e.g. PostgreSQL) supports complex types as a column value. E.g. you may define a column which holds a 2d-array of strings:. CREATE TABLE something( id INTEGER, matrix TEXT[][] ); INSERT INTO something(id, matrix) VALUES( 1, ARRAY[ARRAY['one','two'], ARRAY['three "3"','four']] );.

QUESTION
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.
Error Details
_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_at
datetime(6) NOT NULL,user_id
bigint NOT NULL)' at line 1")
Am I missing anything?
Enumeration class with all choices

Answered 2021-Sep-29 at 19:39You 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.

Let's say I have an organization which contains 25 aws account where each account may or may not contains some reserved RDS instance. So I need to use boto3 to connect my organization and iterate each account to check that RDS reserved instance. What I do on a single account level to check RDS instances.
This Code will list all RDS instances present in the single account
Sample Code
...ANSWER
Answered 2022-Mar-14 at 17:34One way to do this is using a common role. The prerequisite for this approach is that a role, which has access to make the necessary API calls, needs to exist in each of the accounts that belong to the organization. You then assume this common role to perform API calls in the target accounts. This sort of setup is outlined at https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_accounts_access.html.
With that role in place, you can run boto3 code to find all the accounts in your organization--something like this perhaps:

I am using SQlalchemy for the database connection to a MySQL server in my FastAPI project, which consists of the actual API and a backend worker written using arq. Both share the same codebase, models and hence also the same database code.
I'm essentially creating the database connection like this:

Answered 2022-Feb-20 at 12:29In my case I forgot to close the DB connection in some instances and therefore didn't return the connection to the default pool. The logs actually told me about that. I'm not sure why that led to the BrokenPipe error above, but fixing the two affected worker methods solved the issue.

Answered 2022-Feb-11 at 12:45What are the steps I need to do to setup MUC from a fresh install?
Usually mod_muc is already configured and enabled by default. Of course, if ejabberd is installed in a remote server, you will need to setup DNS for the MUC service, similar to what you may want to do for any other services that have their specific domain, like pubsub.example.org

Kindly ask you to help with docker and Postgres.
I have a local Postgres database and a project on NestJS.
I killed 5432 port.
My Dockerfile
ANSWER
Answered 2022-Jan-30 at 17:16- Do not use
sudo
- unless you have to. - Use the latest Postgres release if possible.
The Postgresql Docker Image provides some environment variables, that will help you bootstrapping your database.
Be aware:
The PostgreSQL image uses several environment variables which are easy to miss. The only variable required is POSTGRES_PASSWORD, the rest are optional.
Warning: the Docker specific variables will only have an effect if you start the container with a data directory that is empty; any pre-existing database will be left untouched on container startup.
When you do not provide the POSTGRES_USER
environment variable in the docker-compose.yml file, it will default to postgres
.
Your .env file used for Docker Compose does not contain the docker specific environment variables.

Install db_type
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.
