Django-autocomplete-light 3.4.0 introduced a regression in locale loading, it has been reported by Phil Gyford, thank you !

django-autocomplete-light 3.4.0 release

| by jpic | django-autocomplete-light python
This release re-enables Python 2 and Django 1.11 support, even though it doesn’t pass all tests because tests rely on dicts being ordered by default which came in Python 3 Also, this release exits from using Django’s vendored select2, and vendors select2 itself with a submodule again, this is to benefit from upstream bugfixes faster


| by jpic | python django A Delegative Democracy implementation made in BlackLoop HackerSpace for Les Indignés back in the days I used to squatt hackerspaces in-between gigs (now running my own). It’s a bit old but probably still valid, given the complexity is handled in SQL with a WITH RECURSIVE query. Anyway, hope this will inspire you ! Have a great week

| by jpic | devops python ansible best-practice GitHub release of part of my current production practice to Continuous Integration and Continuous Delivery. It’s the main monolyth that combines well in CI with our Python & PHP distributions. Actually some parts of the monorepo in the process of being extracted and rewritten to smaller sized units and that’s the development track that’s issued recent tools such as cli2 that is the library for decorating another CLI in python extracted as a generic engine, base for djcli (also extracted from injected code from ansible django plugin), shyml, with other parts that are yet to be installed in a production pipeline such as ansible-apply ansible modern command line wrapper, compoctl docker-compose decorator that’s shorter to write but also provides experimental commands to improve automated deployments, backups and restores.

Django & JS research report

| by jpic | python django best-practice npm nodejs js
This article aims to report the current state of research about dealing with both JS and Django, for people that aim to primarly deal with Django and enjoy the same workflow they have with python package with their frontend development, and find patterns to connect them while keeping them loosely coupled at whatever limit feels right for them. Nuff said, let’s hack ! crudlfap relies on django-webpack-loader, which does its job very well. Read More


| by jpic | python django best-practice GDAPS - Generic Django Apps Plugin System Awesome app by Christian González, undergoing research & development for frontend framework plugin EPIC !!! This is the README so far: This library allows Django to make real “pluggable” apps. A standard Django “app” is reusable (if done correctly), but is not really pluggable, like being distributed and “plugged” into a Django main application without modifications. CAVE: This software is in a very early development state. Read More

ansible-compose: deploying docker-compose files over bare ssh

| by jpic | python devops ansible docker docker-compose
In kubernetes, we have the joy of applying configuration directly from maintainer repositories: kubectl apply -f https://raw.github.../setup.yml This allows each repository to maintain its own infrastructure configuration as code, and maintaining a core devops framework in between. You will have to deal with particular credentials, that you should use something else to generate and so on. On the other side of internet, happy docker-composers are also having a lot of fun maintaining them in repositories they contribute to. Read More

Automatic test rewrite for django-dbdiff/django-responsediff/cli2

| by jpic | python django best-practice tdd
Still in the competition for most code coverage with least test code that is written manually and needs to be maintained manually, all our test autowriting software has been updated to support a new environment variable : FIXTURE_REWRITE. Instead of deleting fixtures manually to regenerate them by running the tests, you can now just run your tests with the FIXTURE_REWRITE env var. This will overwrite the fixtures and make the tests look like it passed. Read More

I’ve been upgrading my to setupmeta, which gives me 10 times more useful features than the crappy script I had in my delivery pipelines, and I’m going directly with setupmeta for all new packages. So far, we have at least the following packages with setupmeta (probably more): - cli2 - shyml - djcli - crudlfap - playlabs Even if you don’t maintain python packages, I highly recommend that you check setupmeta because it’s really well thought of.

DevOps since 2005: a  retrospective

PlayLabs: the Obscene Ansible Distribution, long version

| by jpic | python linux ansible best-practice playlabs
From baremetal to deploying docker images on a PaaS in one command ? PlayLabs is the result of a refactor of playbooks we’ve had in production for a while to acheive hackable docker-based PaaS. The refactor was designed to be Open Source, almost there to beta. PlayLabs combines simple ansible patterns with packaged roles to create a docker orchestrated paas to prototype products for development to production. PlayLabs does not deal with HA, for HA you will need to do the ansible plugins yourself, or use kubernetes … but until then, PlayLabs do everything else, even configure your own sentry or kubernetes servers !

CRUDLFA+ 0.3 Series

| by jpic | python django crudlfap
CRUDLFA+ is an expirement (read: pre-alpha state) of what Django could be if: generic views provided templates and javascript for a rich experience out of the box, class based views leveraged OOP a bit more to add DRY goodness, leveraged externals apps from the Django ecosystem.

Model in Django: not what you think they are

| by jpic | python django
It’s funny how my imagination was completely anihilated when I actually read django model field source code. I thought a Django Model was dedicated to designing the database. But a Model field is not a DB Field. A Model field has a DB field, and a formfield method. Unfortunnately, formfield is not changeable unless you override the method which means creating your own model field. Also unfortunate, Model has no form() method like their fields have formfield() method. Read More

Djangonauts: Say no to selenium drug

| by jpic | selenium best-practice python django js
When you start applying best development practices such as TDD, you discover that you make much better software. First, you can TDD your python code with anything, django has a test runner, otherwise you have pytest and many friends. Then, you make python to interact with javascript. In the Django community, it seems that there is a conscensus around “use selenium to test your JS”. I’ve been like this myself for years, but the thing with selenium is that it’s functional testing, not unit testing, it does bring short term ROI, but on the long term it becomes costy to maintain over time.

PHPUnit has had a DBUnit component since at least 10 years, and Junit too, I ported the concept to Django, first in several apps. Extracted it in the package to de-duplicating the data import tests from django-representatives and django-representatives-votes which is re-used in django-cities-light. Read More

get_context_data() considered harmful

| by jpic | django python
Hello everybody <3 Let’s talk about ideas for deprecation / discouraging the use of get_context_data(). get_context_data() is useful to support legacy templates from the pre-CBV era, since CBV we can now access any attributes from the view instance with {{ view }}. I’ve seen things like this in many projects, I wonder if it’s the case for other people too: def get_context_data(self, **kwargs): c = super().get_context_data(**kwargs) c['something'] = self.something return c And I’m guilty as charged you can find commits from myself like this all over internet.

This is supported out of the box with CRUDLFA+, the modern web framework for Django. All you need to implement is: a Model class with what you want in it, just set Meta. Read More

django-session-security 2.4.0 release

| by jpic | django python django-session-security
This new release enforces SESSION_EXPIRE_AT_BROWSER_CLOSE, because it makes no sense to use django-session-security without it, by design. However, a vulnerability caused by having SESSION_EXPIRE_AT_BROWSER_CLOSE disabled was fixed, thanks Clayton Delay for the report.

| by jpic | django python django-autocomplete-light
django-autocomplete-light v3.1.6 was released, thanks to these fine contributions: #671: Create_field support with querysetsequence by @jpic #679: Allow create message translation by @maisim #682: Extend ‘forward’ attribute to creating objects as well by @toudi #666: Improved missing ‘created_field’ error by @guettli #670: Javascript loading documentation by @jpic #678: Added example to update autocompletes in JS by @jpic

django-autocomplete-light 3.1.5 release

| by jpic | django python django-autocomplete-light
This release enables field-forwarding in formsets and forms with prefix. Also note that several things have been made to help users: a new tutorial section showing placeholder and minimum-input-length select2 options has been added and a system check will raise an error if select2’s js is not present - typically for users who have git clone'd the repo without --recursive, resulting in a wc without select2. For devs, we’ve moved from django-sbo-selenium to pytest+splinter and it’s pretty cool ! Read More

django-dbdiff was released. It allows to exclude fields from tests with the new exclude parameter, ie:: Fixture( 'tweets/tests/after_create_retweet.json', models=[Tweet, Retweets], ).assertNoDiff( exclude={ 'tweets.tweet': ['datetime'], 'tweets.retweets': ['datetime'], }, } This was initially requested by Nicolas Joyard for the Political Memory project. Note that you shouldn’t use exclude for datetimes like in the above example, but instead use something like freezegun to force datetimes to an arbitrary fixture.

Porting ModelForm enhancements from django-autocomplete-light v2 to Django

| by jpic | python django django-autocomplete-light xmodelform
Currently, django-autocomplete-light v2 provides enhancement to default form field generation for model fields, depending on the registered autocompletes, as shown in the tutorial. For v3, we don’t want this feature inside DAL anymore because it has really nothing to do with autocomplete. Instead, I’m trying to contribute a generic way to do that. It would not benefit only django-autocomplete-light anymore, but all Django apps. You could get enhanced default form fields for model fields just by installing and configuring apps in your project.

django-autocomplete-light v3: what’s going on

| by jpic | python django django-autocomplete-light
This post clarifies the status of django-autocomplete-light and strategy for v3. Version 2 No further effort will be made to support new versions of Django in v2. However, it supports the current LTS Django 1.8 and future-release Django 1.10, so we’ve got plenty of time to re-do v2’s best features in v3 (in a better way) and most importantly you’ve got plenty of time to upgrade (until 2018). Version 3 It’s a ground-up rewrite and it’s not backward compatible - hence the 2 years upgrade plan. Read More

django-responsediff 0.3.0

| by jpic | python django best-practice django-responsediff
django-responsediff 0.3.0 has been released ! It now also checks the status_code, and has a cute mixin: from responsediff.test import ResponseDiffTestMixin class MixinTest(ResponseDiffTestMixin, test.TestCase): def test_admin(self): self.assertResponseDiffEmpty(test.Client().get('/admin/')) The above will fail on the first time with FixtureCreated to indicate that it has written responsediff/tests/response_fixtures/MixinTest.test_admin/{content,status_code}. This file is meant to be added to version control. So next time this will run, it will check that response.status_code and response.content is the same, in future version, or in other configurations (ie. Read More

django-autocomplete-light 3.0.0 release

| by jpic | django-autocomplete-light django python
After 4 years of supporting django-autocomplete-light, I’m beginning to figure what users expect and the common mistakes, like registering the wrong model for autocomplete, or having troubbles figuring how to link suggestions with other form fields, or create choices on the fly, or with the magic modelform. So at first, I really tried to find other autocompletion apps for with DAL could be just an extension. It turned out that with they had too much security issues, known security vulnerabilities which aren’t going to be fixed (which I don’t dare to post here). Read More

This release fixes an important usability but on the manychoice fields, and introduces a minor backward compatibility break: #563 Don’t disable multiplechoicewidgets if select is [multiple], bd9ca0085 Don’t import anything in init anymore if on django 1.9 test_project fixes, for the above. Disabled field bug Thanks George Tantiras for reporting the bug ! Note that only paliative solutions have been taken for v2: repaired the demo website, should make it easier to spot bugs, bug fix in the JS. Read More

Automatic fixtures for HTTP Response assertions

| by jpic | python django test django-responsediff best-practice
As stated in the “Database state assertion” article: I’m pretty lazy when it comes to writing tests for existing code, however, I’m even lazier when it comes to repetitive manual testing action. When my user tests my website, they browse it and check that everything is rendered fine. In the same fashion, django-responsediff eases doing the high-level assertions of page HTML rendering. Consider this example: class TestYourView(TestCase): def test_your_page(self): result = test. Read More

Django database testing

I’m pretty lazy when it comes to writing tests for existing code, however, I’m even lazier when it comes to repetitive manual testing action, we’ve got so much patches to review and test against so many versions of Python and Django, we need testing to be automated. This article presents a new Django app for testing the database. Java has DBunit and so does PHP, and django now has django-dbdiff. Read More

Django 1.9 support for Django-autocomplete-light

| by jpic | python django django-autocomplete-light
Since Django 1.9a1 was released, many users are going to upgrade their project and wonder why django-autocomplete-light won’t load anymore. Probably, some users are going to google ImportError or even django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet about autocomplete_light and Django 1.9. This post documents the situation and provides a solution. Do: find test/ -name foo -exec sed -i 's/import autocomplete_light/from autocomplete_light import shortcuts as autocomplete_light/' '{}' \; I don’t remember why exactly since we’ve baked Django 1.

Scripted Cache AnyThing - HTTPS included - in Python with mitmproxy

| by jpic | linux python security ci
The last article demonstrated how we could simply make any https flow going out a virtual bridge network interface through mitmproxy to cache anything. In this article, we’ll focus on the logic to “cache anything” from within our mitmproxy script. Design We’d like each fetched file to be stored in a directory as is to make it easy to tweak the cached content: remove a file from the cache directory to force the proxy to re-fetch it, fill the cache directory with your own files, have the cache directory mountable in a memory (ie.

Speed up your travis-ci builds with container based infrastructure

| by jpic | travis-ci python django linux
Travis-ci just released container based infrastructure for open source repository (free users). We tried it with our apps, and you can see we had some performance increase, even on database-intensive jobs: django-autocomplete-light normal build takes around 1 hour and 35 minutes while it takes rather 1 hour and 22 minutes with container based build]( so that’s around a 10% build speed increase, pretty cool right ? read on ;) django-cities-light normal build takes around 5 hours and 45 minutes, on travis-container it takes around 3 hours and 30 minutes !

Django 1.7 new feature: AppConfig

| by jpic | django python
Check out the new applications documentation for Django 1.7 ! It’s still quite cryptic what will “holding app metadata” be really able to do. For starters it enables changing the name of an app in the admin without any hack. It will probably make installing and customizing apps easier, ie.: provides a default setting system, similar to django-appconf, automatically include app-specific stuff like middlewares, urls, etc, etc … ? replace an app’s model ?

Interresting Python and pip behaviour with Python 2 and 3 compatible packages

In this article we’ll explore a gotcha with Python 2 and 3 support on the long run, using Selenium as an example. Selenium is an automated testing tool enabling the tests to control a temporary browser GUI - Firefox by default. You can use it to automate functional testing. Selenium 2.37 had Python 2 and 3 support. But a little before the 2.38 release, some non-Python3-compatible code was commited. This was released in selenium 2. Read More

Using bootstrap and less css in django

Enable global site packages in an existing virtualenv

| by jpic | python virtualenv
Nowadays, virtualenv uses --no-site-packages by default. This means that the created virtualenv will not access global site-packages modules ie. /usr/lib/python2.7/site-packages/. To enable global site-packages again, just remove this file:: your_env/lib/python2.7/no-global-site-packages.txt Why would you do that ? Some modules are complicated to install (xpyb) or take too much time to compile (pyqt). Using the distro packages can be pretty useful !

Jedi-vim/rope takes too long

| by jpic | python vim
For those using jedi-vim are indirectly using rope refactoring library. If you are also using a home-level virtualenv ie. in ~/env/ then your vim instance might take crazy long time. First things first, rope creates a .ropeproject directory where it thinks the project root is. And it will scan every file in every sub directory. A quick and dirty solution is to create empty .ropeproject folders lower in the $HOME filesystem. Read More source code is now open !

Using rst for documentation on both GitHub and Sphinx/RTFD: code-block tip

| by jpic | python documentation service
Good documentation should be readable from source, and usable to generate fancy HTML. That’s why RST is so commonly used: readable as text source, usable to generate HTML and even PDF GitHub knows how to render it, Sphinx and ReadTheDocs know how to render it. Good documentation should often show code. This article demonstrates an inconsistency between RTFD and GitHub rendering, and how to fix it. As far as sphinx is concerned, the default highlight language for code blocks is Python. Read More

Testing django signals properly

| by jpic | python django
Asserting that signals were sent properly can be a bit tricky: they must be sent in a particular order with specific arguments. Fortunately, mock-django provides plenty of cool features, including a nice signal receiver mock. The only problem with mock-django is that it’s not documented. So I had to reverse-engineer and here’s what I’ve found: the best way to test a signal is to use the call_args_list property of the receiver mock. Read More

Django, Pinax, virtualenv, setuptools, pip, easy_install and requirements.txt

| by jpic | django pinax python virtualenv best-practice
This article describes how to build project dependencies with virtualenv. It is appliable to Pinax. Pinax uses virtualenv by default. It lets the developer have a project-specific python directory, including binaries, packages etc … OpenSuse for example supplies very bad Pinax packages which allows the user to mess with his operating system. It is much better to isolate project dependencies from a project to another for more granular control of the maintenance cost; for example if a package upgrade breaks the user project. Read More
