A better and faster multiple selection widget with suggestions for Django
## This project is looking for maintainers!
Please open an issue to request write access.
# What is this?
This plugin provides a replacement for standard multi-choice select on Django admin pages.
You can use this as custom widget for `ManyToManyField`.
# Features
- Filtering is performed on server side and thus significantly improves performance.
- Uses `Twitter Typeahead` to provide suggestion completion.
- Works **great** with ManyToMany fields that can be chosen from thousands of thousands of choices, e. g. `User - City` relations.
### Before
### After
# Installation
1. Install `django-searchable-select`.
```sh
$ pip install django-searchable-select
```
2. Add 'searchableselect' to your settings.
```python
# settings.py
INSTALLED_APPS = (
# ...
'searchableselect',
# ...
)
```
3. Add URL pattern required for the suggesting engine to your root `urls.py`.
```python
# urls.py
urlpatterns = patterns(
'',
# ...
url('^searchableselect/', include('searchableselect.urls')),
# ...
)
```
4. Use the widget in your model admin class:
```python
from django import models, forms
from searchableselect.widgets import SearchableSelect
from models import Traveler
class TravelerForm(forms.ModelForm):
class Meta:
model = Traveler
exclude = ()
widgets = {
'cities_visited': SearchableSelect(model='cities.City', search_field='name', many=True, limit=10)
}
class TravelerAdmin(admin.ModelAdmin):
form = TravelerForm
admin.site.register(Traveler, TravelerAdmin)
```
Remember to **always** initialize `SearchableSelect` with three keyword arguments: `model`, `search_field` and `many`.
- `model` is the string in form `APP_NAME.MODEL_NAME` representing your model in the project, e. g. 'cities.City'
- `search_field` is the field within model that will be used to perform filtering, e. g. 'name'
- `many` must be `True` for `ManyToManyField` and `False` for `ForeignKey`.
- `limit` (optional) specifies the maximum count of entries to retrieve.
# Example app
Just run the project from `example` directory, head to http://127.0.0.1:8000, login as `admin`/`admin` and try adding Cats!
# Supported versions
- Python 2.7.x: Django 1.7, 1.8, 1.9, 1.10
- Python 3.x: Django 1.8, 1.9, 1.10, 2.0
# Testing
In order to support multiple Django and Python versions we use:
- `py.test` - test runner
- `tox` - handy tool to test app with different versions of Pythons & libraries
- `selenium`
- `coverage`
Install them via `pip install -r requirements/dev.txt`
To test things in specific environment, run the following commands:
```sh
# Clear previous coverage data.
coverage erase
# This command can be ran multiple times.
tox -e -
# Possible python_ver values: `py27`, `py36`
# Possible django_ver values: `17`, `18`, `19`, `110`, '20'
# Values can be comma-separated, e. g. `-e py27-17,py27-18,py36-18`
# If you omit `-e ...` parameter, all environments will be tests.
# Also - not problems with running this within a virtualenv.
# Check tox.ini for these values.
# Run this once all tests passed on all environment.
coverage combine
# Render HTML with coverage info.
coverage html
# ...or simply display % of covered SLOC for each file.
coverage report
```
To add a new Django version for testing, add it into `tox.ini`, lines 3-4.
Why do we need `tox` and `coverage combine`? Because different versions of Python & libraries lead to different code execution: for example, consider this code:
```python
import sys
if sys.version_info.major == 2:
foo = 'spam' # Not covered in Python 3.x, leads to coverage < 100%
else:
foo = 'eggs' # Not covered in Python 2.x, leads to coverage < 100%
```
Using `tox` and `coverage combine` we're able to "merge" coverage info from across different environments.
# Known issues
- Not tested with empty fields.
- Tests sometimes fail randomly due to some Selenium timeout issue. Weird.
# Contributing
I'm looking forward to bug reports and any kind of contribution.
