django-simple-select

A simple jQueryUI autocomplete <select> replacement for Django.

This project is meant to be an easy replacement for the Select widget when you have too many objects to sensibly use it.

Requirements

• jQuery
• Twitter Bootstrap
• selectize

Features

Good "does nots":

• Doesn't require any SQL tables.
• Doesn't change your POSTdata.

Not-strictly-good "does nots":

• Doesn't have any API documentation (yet!)

This is in extremely early alpha status; I've only put it on PyPI for the sake of the project I've created for.

Originally there was an intention to have this be a lightweight dependency (i.e. require not much beyond jQuery), but I've nixed that in favor of me writing lightweight code. So this at the moment has a hard dependency on both Twitter Bootstrap and the selectize library.

Quickstart

1. pip install django-simple-select

2. Add simpleselect to INSTALLED_APPS in your project's settings.py.

   Note

   This is only for the sake of being able to include the JS file. It may be possible to remove this step, so it may vanish from a future version.

3. Add this to your urls.py

   # other urls...
   url('^', include('simpleselect.urls')),
   # ...

4. In your form, make use of a simpleselect.AutocompleteSelect in a ModelChoiceField, e.g.

   Warning

   This whole step is out of date. From this point on this documentation is unreliable. Hopefully I will come back and update these docs on my own time.

   class MyForm(django.forms.ModelForm):
   
       class Meta:
   
           model = models.Person
           widgets = {
               'employer': simpleselect.AutocompleteSelect(
                   ['name__icontains']),
           }
   
   
   class AddPersonForm(django.forms.ModelForm):
   
       _personwidget = simpleselect.AutocompleteSelect(
           ['first_name__icontains', 'last_name__icontains'])
   
       person = django.forms.ModelChoiceField(models.Person.objects.all(),
                                              widget=_personwidget)

   The autocomplete widget takes a list of Django field lookups. When autocompleting, it splits the search string. For each individual word, it ORs together all lookups applied ot that word. It then ANDs together the results of that process applied to all words.

   E.g.: for a widget like

   simpleselect.AutocompleteSelect(['first_name__icontains',
                                    'last_name__icontains'])

   and a search string like

   "John Smi"

   your final query is equivalent to this, built using Django Q objects:

   ((Q(first_name__icontains='John') | Q(last_name__icontains='John'))
    & (Q(first_name__icontains='Smi') | Q(last_name__icontains='Smi')))

   This seems to be the correct thing to do, at least most of the time. But I am no expert. More documentation coming!

5. Add this to your template

   {% load staticfiles %}
   
   <script type="text/javascript" src="{% static "simpleselect.js" %}"></script>

6. Unless I forgot something else while writing this, you should be good to go!

Discussion/help

For now, feel free to message me directly on Github or open a ticket. There's no mailing list or anything fancy like that. If this picks up any steam I'll add that stuff.
