• Django Admin tip: Auto-generated slug content

  Posted on April 6, 2021 at 6:32 p.m. by Filip Němeček's Blog RSS
  <![CDATA[ Django Admin tip: Auto-generated slug content In this post I want to share super quick tip that can help you a lot, assuming you use Django Admin and at least some slug fields. Slugs are these human readable parts of an URL, that also let you identify a piece of content. For example this URL: https://nemecek.be/blog/79/working-with-django-imagefield. The last part is a slug based on the post title "Working with Django ImageField". The motivation for slugs is that URLs cannot contain spaces (among other characters) so we use process which is called "slugify" to turn a piece of text into valid slug. Django offers a SlugField which will automatically validate its input to allow only slugs and you can use these as part of the URL. And now we can finally move to the tip. Django ModelAdmin has setting called prepopulated_fields which is mainly there for automatic slug creation. We can use an example from the official docs: class ArticleAdmin(admin.ModelAdmin): prepopulated_fields = {"slug": ("title",)} This will monitor the value of title input and automatically create slugified version with the help of JavaScript. Django also makes sure to not automatically update this slug later on, because you probably don't want your …

• Guest Post: Django Crispy Forms Advanced Usage Example

  Posted on April 5, 2021 at 11:41 a.m. by DjangoTricks RSS
  This is a guest post by Serhii Kushchenko, Python/Django developer and data analyst. He is skillful in SQL, Python, Django, RESTful APIs, statistics, and machine learning. This post aims to demonstrate the creation and processing of the large and complex form in Django using django-crispy-forms. The form contains several buttons that require executing different actions during the processing phase. Also, in the form, the number of rows and columns is not static but varies depending on some conditions. In our case, the set of rows and columns changes depending on the number of instances (columns) associated with the main object (data schema) in a many-to-one relationship. The django-crispy-forms documentation includes a page Updating layouts on the go. That page is quite helpful. However, it does not contain any detailed example of a working project. IMHO such an example is much needed. I hope my project serves as a helpful addition to the official Django Crispy Forms documentation. Feel free to copy-paste the pieces of code that you find applicable. Please see the full codebase here. It is ready for Heroku deployment. Task Suppose we have a database with information about people: name, surname, phone numbers, place of work, companies owned, …

• Django modify_settings and receivers

  Posted on March 31, 2021 at 6:47 p.m. by Schinckel.net RSS
  Sometimes, tests expose weird behaviour. In this instance, I have a `Makefile` command that calls a `cookiecutter` command to create a new integration with a payroll system. We'd noticed that over time, this infrequntly used code had become slightly less than perfect. So, I wrote a test that runs this code. Not directly using the `make new-payroll-system` command, but rather using a test case from within Django. This worked great in development. I was able to have code that was generated, some tests on that code were run (including generating migrations for the new app), and then the code was removed. {% highlight python %} def test_cookie_cutter(self): from cookiecutter.main import cookiecutter try: cookiecutter( 'integrations/__template__', extra_context={'system_name': 'new_thing'}, output_dir='integrations/systems', no_input=True, ) with modify_settings(INSTALLED_APPS={'append': 'integrations.systems.new_thing'}): call_command('makemigrations', 'new_thing', no_input=True, verbosity=0) finally: shutil.rmtree('integrations/systems/new_thing') {% endhighlight %} But this failed in CI. Turns out that our Codeship-based testing infrastructure doesn't allow for writing the files in the expected location. Never mind, we can use `tempfile.TemporaryDirectory()` instead. That will handle the cleanup for us, which is better than removing files ourselves: {% highlight python %} def test_cookie_cutter(self): from cookiecutter.main import cookiecutter with tempfile.TemporaryDirectory() as dirname: # Put our new temporary directory on the PYTHONPATH. sys.path.insert(0, dirname) cookiecutter( …
