This article is the 10th day article of Django Advent Calender 2016.
Hello! I've been an engineer for about 3 years since I started using Django in my current job. This time, I would like to introduce the Django-related library that I am currently using, which also serves as a means of organizing my own knowledge.
django-storages https://pypi.python.org/pypi/django-storages
A library for delivering static files on a CDN such as Amazon S3. A fork version called django-storages-redux was born because it wasn't compatible with Python3, but now it supports up to the latest 3.5. doing. Recently, whitenoise seems to be popular, and I'm thinking of switching if it's okay to try it.
django-compressor https://pypi.python.org/pypi/django_compressor/2.1
It is a library that combines multiple css and js files into one. There is also a function that embeds the contents inline and reduces the amount of data transfer by looking at line breaks and comments. It can also be combined with compilers such as altJS and Sass (SCSS).
easy-thumbnails https://pypi.python.org/pypi/easy-thumbnails/2.3
It is a library that generates so-called "thumbnail images". If the image that is the source of the thumbnail image is deleted, only the thumbnail image will remain as garbage, so you need to delete it regularly with the thumbnail_cleanup command.
django-haystack
https://pypi.python.org/pypi/django-haystack/2.5.1
I use it to do location information in Elasticsearch.
When using location information, you can only search in the environment where libgeoip is installed.
django-extensions https://pypi.python.org/pypi/django-extensions/1.7.5
It's a library that makes Django's features even more powerful, with the feeling that it's within reach. I especially like the following commands.
--runserver_plus command
--Code can be executed on any line of the stack trace when an error occurs.
--shell_plus command
--The shell is started with frequently used import statements such as the model class and from django.conf import settings pre-executed.
django-formtools https://pypi.python.org/pypi/django-formtools/1.0
It is a library to realize the movement of "input" → "confirmation" → "send" that is often found in inquiry forms. Originally built into Django itself, it's now independent from 1.8.
django-model-utils https://pypi.python.org/pypi/django-model-utils/2.6
It is a library that allows you to concisely write patterns that are often used in model design.
StatusField or [Choices](http://django-model-utils.readthedocs.io/en/ The latest / utilities.html # choices) class is often used because it's a cleaner way to write a field like "status" where you can only enter a predetermined value, rather than passing a tuple to the choices attribute normally. I will.
django-braces https://pypi.python.org/pypi/django-braces
A library of mixed-in classes of Class-based views. If you read the Documents carefully before you start development, it will be easier for you to proceed. For LoginRequiredMixin, LoginRequiredMixin is standard from Django 1.9. Now that you have / en / dev / topics / auth / default / # the-loginrequired-mixin), you should use the standard.
django-debug-toolbar https://pypi.python.org/pypi/django-debug-toolbar/1.6
A library that displays a debugging toolbar on the right side of the browser screen.
It is useful to check the output contents of the log and the query thrown to the DB.
There is also a handy command called debugsqlshell that will parse the queries that are thrown by model operations from the shell.
django-haystack-panel https://pypi.python.org/pypi/django-haystack-panel/0.2.1
An extension of django-debug-toolbar that parses queries thrown from django-haystack.
REST API djangorestframework https://pypi.python.org/pypi/djangorestframework/3.5.3
A standard library for creating services that provide REST APIs in Django. It's quite sophisticated, so depending on what you want to make, django-braces' JSONResponseMixin, JsonRequestResponseMixin, AjaxResponseMixin You should use it.
django-fancy-cache https://pypi.python.org/pypi/django-fancy-cache
A library for things like "clear a specific page cache when this data is updated". (The standard page cache can't do that unexpectedly ...)
django-axes https://pypi.python.org/pypi/django-axes
It is a library that freezes the login screen for a while if login fails a certain number of times. It is introduced as a countermeasure against bots trying to steal accounts with brute force (or reverse brute force). Since logs are spit out at the WARN level when frozen, it is a policy to notify by e-mail or Slack and block IP addresses that persistently retry with a firewall.
django-password-validation https://pypi.python.org/pypi/django-password-validation
You can force a somewhat complicated password when registering or updating a password. [Password validation] introduced from Django 1.9 This library backports (https://docs.djangoproject.com/en/dev/topics/auth/passwords/#password-validation) to 1.8 or earlier. The service I'm working on now uses 1.8, so I introduced it.
