Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

A pure JavaScript library to manage Django formsets

Readme

django-fancy-formset

This is a plain JavaScript library to let users add and remove forms in a Django inline formset. It can be installed from PyPI as a Django app, from NPM as a JavaScript module, or linked to directly from your HTML.

PyPi version Npm version Documentation CI

Features:

  • No dependencies, just 5kB of plain JavaScript
  • Apply to formsets manually, or automatically via a data- attribute
  • Optional Django app to simplify usage
  • Raises events to allow for customisation
  • Class based and designed to be extended
  • Default styling available

Quickstart using Python

Install with:

pip install django-fancy-formset

Add to your INSTALLED_APPS, then create your formsets using the provided fancy formset classes:

from fancy_formset import FancyInlineFormSet

BookInlineFormSet = forms.inlineformset_factory(
    Author, Book, formset=InlineFancyFormSet,
)

then leave it to Django to render your formset:

{{ formset.media }}
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  {{ formset.as_p }}
  <button type="submit">Save</button>
</form>

See the Django installation documentation for more details

Quickstart using JavaScript

The Python package is a thin wrapper around the JavaScript package. For more control, you can integrate it yourself.

Add to your page directly using unpkg:

<html>
  <head>
    <!-- Optional styles -->
    <link rel="stylesheet" href="https://unpkg.com/django-fancy-formset@^1/dist/formset.min.css">
  </head>
  <body>
    <!-- Django formset goes here -->
    <script src="https://unpkg.com/django-fancy-formset@^1"></script>
    <script>formset.init();</script>
  </body>
</html>

You can also use it in your bundler or browser as module - see the JavaScript-only installation documentation for more details

Render your formset in your Django template. The template structure which will work with the default configuration is:

<form method="post">
  {% csrf_token %}
  {{ form.as_p }}

  <h2>Formset</h2>
  <div data-formset="{{ formset.prefix }}">   {# Formset container to target #}
    {{ formset.management_form }}             {# Add the management form #}
    <fieldset style="display: none">          {# Add and hide the empty form #}
      {{ formset.empty_form.as_p }}
    </fieldset>
    {% for form in formset %}
      <fieldset>                              {# Each formset form has a container #}
      {{ form.as_p }}                         {# Actual form layout doesn't matter #}
      </fieldset>
    {% endfor %}
  </div>

  <button type="submit">Save</button>
</form>

This can all be customised with options passed as formset.init(options) - see the configuration documentation for details.
