kandi X-RAY | FlaskAuth Summary
A web app written with Python Flask framework that allows users to create accounts, login, and modify there information. Code is commented and provides tutorials for flask, sql and jinja2 templating. Might provide app specific documentation later. NOTE This app is a stripped down, ugly example from a larger app I am building. I am posting it here as a resource for others to use to learn Flask and start playing with the framework in a development environment. To start using this code quickly follow these steps. 1.) create a free account at pythonanywhere.com 2.) in the consoles tab open a bash console and run the following; git init git clone 3.) this should Clone this entire repo and create a FlaskAuth folder in your pythonanywhere directory. 4.) in the Web tab create a new web app. Select flask framework, and Python 2.7. 5.) When the Path appears on the next screen remove "mysite" from the path and add "FlaskAuth". Leave everything else in the path alone!! 6.) Now go to the files tab. Open FlaskAuth and look for the run.py file. Copy its single line of code to file that the web app wizard created in step 5. 7.) To set up the database go to the Database tab and set a SQL password. Then create a database. Before leaving this screen note the following; server name, mysql username, mysql password (you just set it), and finally the database name(you just named it) 8.) Take the information from the database you created in step 7 and go to FlaskAuth/app/views.py and at about line 20 where the mysql database connection credientials are, populate the code with YOUR server name, username, password, and name of database 9.) Next go to the Upload Folder variable at around line 30 and change it to make sure it reflects the path to YOUR profilepics folder in static/images. 10.) Finally, go to db.txt in the root of the repo and copy the sql code at the bottom. Go to the consoles tab again and open a MySQL console. 11.) In the MySQL console run 'show databases;' and look for the one you created in step 7. Once you see it type 'use that$database' where that$database is the database YOU created in STEP 7 and not this instructional place holder. 12.) Now paste the Create Table code from Step 10 into the console (control+v). That is all folks. now go to the Web tab and click on the big url for your app. if everything went well you should be greeted with the apps index page and the join / signin boxes. If ANY part of this was screwed up dont expect it to work since the app depends on the database being configured as outlined. I will try to release a screen cast about this if there are very many problems.

QUESTION
Not really sure what caused this but most likely exiting the terminal while my rails server which was connected to PostgreSQL database was closed (not a good practice I know but lesson learned!)
I've already tried the following:
- Rebooting my machine (using MBA M1 2020)
- Restarting PostgreSQL using homebrew
brew services restart postgresql
- Re-installing PostgreSQL using Homebrew
- Updating PostgreSQL using Homebrew
- I also tried following this link but when I run
cd Library/Application\ Support/Postgres
terminal tells me Postgres folder doesn't exist, so I'm kind of lost already. Although I have a feeling that deleting postmaster.pid would really fix my issue. Any help would be appreciated!

Answered 2022-Jan-13 at 15:19My original answer only included the troubleshooting steps below, and a workaround. I now decided to properly fix it via brute force by removing all clusters and reinstalling, since I didn't have any data there to keep. It was something along these lines, on my Ubuntu 21.04 system:

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,

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.
QUESTION
I am having difficulties to scaffold an existing MySQL database using EF core. I have added the required dependencies as mentioned in the oracle doc:
...ANSWER
Answered 2021-Dec-12 at 10:11I came across the same issue trying to scaffold an existing MySQL database. It looks like the latest version of MySql.EntityFrameworkCore (6.0.0-preview3.1) still uses the EFCore 5.0 libraries and has not been updated to EFCore 6.0.
It also seems Microsoft.EntityFrameworkCore.Diagnostics was last implemented in EFCore 5 and removed in 6.
When I downgraded all the packages to the 5 version level, I was able to run the scaffold command without that error.
QUESTION
I'm using Lambda with RDS Proxy to be able to reuse DB connections to a MySQL database.
Should I close the connection after executing my queries or leave it open for the RDS Proxy to handle?
And if I should close the connection, then what's the point of using an RDS Proxy in the first place?
Here's an example of my lambda function:
...ANSWER
Answered 2021-Dec-11 at 18:10The RDS proxy sits between your application and the database & should not result in any application change other than using the proxy endpoint.
Should I close the connection after executing my queries or leave it open for the RDS Proxy to handle?
You should not leave database connections open regardless of if you use or don't use a database proxy.
Connections are a limited and relatively expensive resource.
The rule of thumb is to open connections as late as possible & close DB connections as soon as possible. Connections that are not explicitly closed might not be added or returned to the pool. Closing database connections is being a good database client.
Keep DB resources tied up with many open connections & you'll find yourself needing more vCPUs for your DB instance which then results in a higher RDS proxy price tag.
And if I should close the connection, then what's the point of using an RDS Proxy in the first place?
The point is that your Amazon RDS Proxy instance maintains a pool of established connections to your RDS database instances for you - it sits between your application and your RDS database.
The proxy is not responsible for closing local connections that you make nor should it be.
It is responsible for helping by managing connection multiplexing/pooling & sharing automatically for applications that need it.
An example of an application that needs it is clearly mentioned in the AWS docs:
Many applications, including those built on modern serverless architectures, can have a large number of open connections to the database server, and may open and close database connections at a high rate, exhausting database memory and compute resources.
To prevent any doubt, also feel free to check out an AWS-provided example that closes connections here (linked to from docs), or another one in the AWS Compute Blog here.

QUESTION
Our stack is nodejs with MySQL we're using MySQL connections pooling our MySQL database is managed on AWS aurora . in case of auto failover the master DB is changed the hostname stays the same but the connections inside the pool stays connected to the wrong DB. The only why we found in order to reset the connection is to roll our servers.
this is a demonstration of a solution I think could solve this issue but I prefer a solution without the set interval
...ANSWER
Answered 2022-Feb-04 at 12:22Instead of manually monitoring the DB health, as you have also hinted, ideally we subscribe to failover events published by AWS RDS Aurora.
There are multiple failover events listed here for the DB cluster: Amazon RDS event categories and event messages
You can use and test to see which one of them is the most reliable in your use case for triggering poolCluster.end()
though.

QUESTION
I am following this tutorial on migrating data from an oracle database to a Cloud SQL PostreSQL instance.
I am using the Google Provided Streaming Template Datastream to PostgreSQL
At a high level this is what is expected:
- Datastream exports in Avro format backfill and changed data into the specified Cloud Bucket location from the source Oracle database
- This triggers the Dataflow job to pickup the Avro files from this cloud storage location and insert into PostgreSQL instance.
When the Avro files are uploaded into the Cloud Storage location, the job is indeed triggered but when I check the target PostgreSQL database the required data has not been populated.
When I check the job logs and worker logs, there are no error logs. When the job is triggered these are the logs that logged:
...ANSWER
Answered 2022-Jan-26 at 19:14This answer is accurate as of 19th January 2022.
Upon manual debug of this dataflow, I found that the issue is due to the dataflow job is looking for a schema with the exact same name as the value passed for the parameter databaseName
and there was no other input parameter for the job using which we could pass a schema name. Therefore for this job to work, the tables will have to be created/imported into a schema with the same name as the database.
However, as @Iñigo González said this dataflow is currently in Beta and seems to have some bugs as I ran into another issue as soon as this was resolved which required me having to change the source code of the dataflow template job itself and build a custom docker image for it.
QUESTION
I have to move a large Odoo(v13) database almost 1.2TB(DATABASE+FILESTORE), I can't use the UI for that(keeps loading for 10h+ without a result) and I dont want to only move postgresql database so I need file store too, What should I do? extract db and copy past the filestore folder? Thanks a lot.
...ANSWER
Answered 2022-Jan-14 at 16:59You can move database and filestore separately. Move your Odoo PostgreSQL database with normal Postgres backup/restore cycle (not the Odoo UI backup/restore), this will copy the database to your new server. Then move your Odoo filestore to new location as filesystem level copy. This is enough to get the new environment running.
I assume you mean moving to a new server, not just moving to a new location on same filesystem on the same server.
