I have an application launched in Django, which has a very high traffic of requests and queries to the databases. I am having problems and I have read that with PGBouncer and some settings in Django I can solve the problem.
The question is how to integrate PGBouncer with Django.
I have the Django application in Docker.
The database is Postgres and it is in the RDS service of Amazon web services.
Would PGBouncer be installed on the instance where the Django application runs?

I have an issue where I can login to Django via my development server but it will not work on the production server. I am using Heroku to deploy. All the pages work correctly but I can't login to my Django database.
Your user credentials are stored in your database.
If you have a different database Server in Production which is hosted online it won’t have the credentials stored that you have in your local development database.
So you basically have to get into your deployed Django app using ssh or so and run „createsuperuser“ there again.
Alternatively you could copy the user credentials from you local database and push them to your production database; but just creating new ones will probably be easier if you don’t have to deal with a lot of users.
If you were using Django with „default settings“ it is using an SQLite file (= database).
In Production for a Webapp hosted online it will be most likely a „real database server” (DBMS) like PostgreSQL or MySQL or so as SQLite is fine for development and testing, but struggles with concurrent user access to data.
If you are configured different database in your production server you have to execute migrations and createsuperuser. Then you'll able to login.
Your current user credentials are saved in your database which is configured in local server.
I'm planing to built an app using Django with SQL Server. But I'm going to develop the app in my computer but the database is already exist in other computer/server.
How can I connect to that database in the other server and connect the Django which is in my computer? They are separate computers.
I have a web application written in Python-Flask with database created using MySQL. I have deployed my app using Heroku but it's only the frontend and backend part. I also need to upload database so that the app can interact with the database. I have searched many videos on YouTube but nothing came as useful. Most of them are using Postgre SQL both in local and heroku app but I've an MySQL database with me. I need help how can I connect my app to my database.
Heroku has native support for postgessql not mysql, so you might want to change to that or use the Clear DB addon as explained in the docs.
From heroku
"Heroku provides three managed data services to all customers:
Heroku Postgres, Heroku Redis, Apache Kafka on Heroku"
Also have a look at this previous answer that targets the same issue.
What is the definition of a Django application? Any application that uses Django features, such as orm and url-view mapping?
I ask because I have a component which has 2 sub-components: a web service server and a standalone application. The web service server uses Django views to map url to request handlers. The web service server and the application use Django models and a database managed by Django. The web service server obviously needs to be a Django application. The standalone application must be a Django application as well?
Thanks in advance.
No, importing your models is enough, as long as you have Django installed and correctly configured.
I'm reading conflicting reports about using PostgreSQL on Amazon's Elastic Beanstalk for python (Django).
Some sources say it isn't possible: (http://www.forbes.com/sites/netapp/2012/08/20/amazon-cloud-elastic-beanstalk-paas-python/). I've been through a dummy app setup, and it does seem that MySQL is the only option (amongst other ones that aren't Postgres).
However, I've found fragments around the place mentioning that it is possible - even if they're very light on detail.
I need to know the following:
Is it possible to run a PostgreSQL database with a Django app on Elastic Beanstalk?
If it's possible, is it worth the trouble?
If it's possible, how would you set it up?
Postgre is now selectable from the AWS RDS configurations. Validated through Elastic Beanstalk application setup 2014-01-27.
Is it possible to run a PostgreSQL database with a Django app on
Elastic Beanstalk?
Yes. The dummy app setup you mention refers to the use of an Amazon Relational Database Service. At the moment PostgreSQL is not available as an Amazon RDS, but you can configure your beanstalk AMI to act as a local PostgreSQL server or set up your own PostgreSQL RDS.
If it's possible, is it worth the trouble?
This is really a question about whether it is worth using an RDS or going it alone, which boils down to questions of cost, effort, usage, required efficiency etc. It is very simple to switch database engines serving django so if you change your mind it is easy to switch set up.
If it's possible, how would you set it up?
Essentially you need to customise your beanstalk AMI by installing a PostgreSQL database server on an Amazon linux EB backed AMI instance.
