In this video will show you how to use a database connection URL to configure the database in your Django project instead of the default configuration dictionary that can be tedious to use.

A simple Boilerplate to Setup Authentication using Django-allauth, with a custom template for login and registration using

virtual environmentfor this project:
# creating pipenv environment for python 3 $ virtualenv venv # activating the pipenv environment $ cd venv/bin #windows environment you activate from Scripts folder # if you have multiple python 3 versions installed then $ source ./activate
SECRET_KEY = #random string DEBUG = #True or False ALLOWED_HOSTS = #localhost DATABASE_NAME = #database name (You can just use the default if you want to use SQLite) DATABASE_USER = #database user for postgres DATABASE_PASSWORD = #database password for postgres DATABASE_HOST = #database host for postgres DATABASE_PORT = #database port for postgres ACCOUNT_EMAIL_VERIFICATION = #mandatory or optional EMAIL_BACKEND = #email backend EMAIL_HOST = #email host EMAIL_HOST_PASSWORD = #email host password EMAIL_USE_TLS = # if your email use tls EMAIL_PORT = #email port
change all the environment variables in the
.env.sampleand don't forget to rename it to
After Setup the environment, you can run the project using the
Makefile provided in the project folder.

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

let’s just get into this diagram that I made so in here:
Describe each parameter in Django querset
we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.
Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.

In our previous posts in this series, we spoke at length about using PgBouncer and Pgpool-II , the connection pool architecture and pros and cons of leveraging one for your PostgreSQL deployment. In our final post, we will put them head-to-head in a detailed feature comparison and compare the results of PgBouncer vs. Pgpool-II performance for your PostgreSQL hosting !
The bottom line – Pgpool-II is a great tool if you need load-balancing and high availability. Connection pooling is almost a bonus you get alongside. PgBouncer does only one thing, but does it really well. If the objective is to limit the number of connections and reduce resource consumption, PgBouncer wins hands down.
It is also perfectly fine to use both PgBouncer and Pgpool-II in a chain – you can have a PgBouncer to provide connection pooling, which talks to a Pgpool-II instance that provides high availability and load balancing. This gives you the best of both worlds!
While PgBouncer may seem to be the better option in theory, theory can often be misleading. So, we pitted the two connection poolers head-to-head, using the standard pgbench tool, to see which one provides better transactions per second throughput through a benchmark test. For good measure, we ran the same tests without a connection pooler too.
All of the PostgreSQL benchmark tests were run under the following conditions:
We ran each iteration for 5 minutes to ensure any noise averaged out. Here is how the middleware was installed:
Here are the transactions per second (TPS) results for each scenario across a range of number of clients:
