• Professionalism: You should maintain a transition file

  Posted on Nov. 9, 2022 at midnight by Jacob Kaplan-Moss RSS
  When you change jobs, ideally you’ll have the opportunity to brief your successor directly. But that isn’t always possible: you might get fired or laid off, you might leave for another job without a clear successor named before your last day, you might have to take sudden medical leave, etc. Situations like that will be disruptive, it’s unavoidable, but a transition file will help minimize that disruption.

• Django: Customizing how a model form renders fields

  Posted on Nov. 6, 2022 at 9:25 a.m. by Filip Němeček's Blog RSS
  <![CDATA[ Django: Customizing how a model form renders fields I recently wanted to improve my form that contains a couple of ImageField fields. I wanted to display a small preview of the image to remind users what they saved for this particular model. Since I am using the Django Form API to render the form in a template without providing my own HTML, I couldn’t add more HTML to show the preview. Instead, what you can do is to provide custom “widgets” for some of the fields in your model form. I will use my implementation as an example, but you could use this same approach for other form fields to customize how they get rendered. Initial setup To get the ability to customize the widgets, you need to do a bit of configuration in the settings.py. You need to add 'django.forms' to your INSTALLED_APPS and add this line: FORM_RENDERER = 'django.forms.renderers.TemplatesSetting' TimonWeb has a bit more info about this. Creating your custom template The next step is to create your template in the templates directory. Creating a custom widget template is easier than it sounds since you can look at the base widget templates in Django to get the …

• Reusable cookie consent app for Django

  Posted on Nov. 4, 2022 at 3:20 a.m. by 406.ch: Posts about Django RSS
  Reusable cookie consent app for Django We at Feinheit have been working on a cookie consent app for some time. Why and what? There are many many solutions in this problem space already. We have used several scripts in the past. Some are simple banners or popups which only inform users that cookies are being used. It is our view and belief that this isn’t sufficient to fulfil the legal obligations imposed by the GDPR and other comparable legislations. We wanted a way to ask for consent and only embed any third party scripts after the consent has been given, not use some other tool which only comes into action after e.g. the Google Analytics scripts already have been loaded. Accepting only essential cookies is made very annoying by some cookie banners. They drown users in options and nudge (or maybe coerce) them towards accepting all cookies. The banner buttons are inspired (stealed) from Twitter, we think it’s nice to offer as little options as possible. Embedding third party content Also, we wanted to integrate a solution for embedding content from third party sites (e.g. Vimeo, Mailchimp and friends) where consent was asked as well when users only accept essential …

• django-upgrade Mega Release 1.11.0

  Posted on Oct. 25, 2022 at 11 p.m. by Adam Johnson RSS
  I just released version 1.11.0 of django-upgrade, a tool for automatically upgrading your Django project code. This release contains a lot of new features and fixes, thanks to new contributors including those at the Djangocon Europe sprints. Let’s look at the top changes. New admin.site.register() fixer Originally the Django admin required you to first define a ModelAdmin class, and then later register Model classes to use it with admin.site.register(): from django.contrib import admin class MyCustomAdmin(admin.ModelAdmin): ... admin.site.register(MyModel1, MyCustomAdmin) admin.site.register(MyModel2, MyCustomAdmin) With this format, the register() calls can become quite separated from the admin classes. In more complicated scenarios, you might also miss exactly which Model classes are registered to an admin class. To solve these problems, Django 1.7 (September 2014!) added the admin.register() class decorator: from django.contrib import admin @admin.register(MyModel1, MyModel2) class MyCustomAdmin(admin.ModelAdmin): ... django-upgrade can now automatically upgrade from the first form to the second: from django.contrib import admin +@admin.register(MyModel1, MyModel2) class MyCustomAdmin(admin.ModelAdmin): ... -admin.site.register(MyModel1, MyCustomAdmin) -admin.site.register(MyModel2, MyCustomAdmin) This works with various forms of admin.site.register() calls, and with GIS admin aliases as well. Thanks to Thibaut Decombe for contributing this feature. New @admin.action() and @admin.display() fixers The Django admin has two special kinds of functions: actions and display functions. …

• How to Handle Django Forms within Modal Dialogs

  Posted on Oct. 21, 2022 at 9:50 p.m. by DjangoTricks RSS
  I like django-crispy-forms. You can use it for stylish uniform HTML forms with Bootstrap, TailwindCSS, or even your custom template pack. But when it comes to custom widgets and dynamic form handling, it was always a challenge. Recently I discovered htmx. It's a JavaScript framework that handles Ajax communication based on custom HTML attributes. In this article, I will explore how you can use django-crispy-forms with htmx to provide a form with server-side validation in a modal dialog. The setup For this experiment, I will be using these PyPI packages: Django - my beloved Python web framework.django-crispy-forms - library for stylized forms.crispy-bootstrap5 - Bootstrap 5 template pack for django-crispy-forms.django-htmx - some handy htmx helpers for Django projects. Also, I will use the CDN versions of Bootstrap5 and htmx.

• Migrate PostgreSQL ID’s from serial to identity after upgrading to Django 4.1

  Posted on Oct. 20, 2022 at 11 p.m. by Adam Johnson RSS
  The Django 4.1 release notes feature this short, innocent-looking note: On PostgreSQL, AutoField, BigAutoField, and SmallAutoField are now created as identity columns rather than serial columns with sequences. In this post, we’ll expand on what this means, why you might want to update existing columns from serial types to identity columns, and a management command to update them. Serial versus identity What are “identity” and “serial” columns? Well, basically they’re PostgreSQL’s two different ways to create auto-incrementing ID columns. Originally PostgreSQL only had serial types, used like: CREATE TABLE example ( id serial NOT NULL PRIMARY KEY ); These serial types are not true data types. Instead, it’s a shorthand that creates a column and a sequence for its default value. PostgreSQL 10 (Oct 2017) added support for SQL-standard identity columns, used like: CREATE TABLE example ( id integer NOT NULL PRIMARY KEY GENERATED BY DEFAULT AS IDENTITY ); (Documented under CREATE TABLE, search for “identity” on the page.) As the syntax shows, the column has a data type, integer, and then “identity” behaviour on top of that. There is an associated sequence for generating values, but PostgreSQL manages this internally. For regular usage, there is not much difference between …
