-# django-searchable-select
-
-[](https://travis-ci.org/and3rson/django-searchable-select) [](https://coveralls.io/github/and3rson/django-searchable-select?branch=master)
-
-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.
-
