Custom form widget for rendering an autocomplete (using jQuery UI's autocomplete widget) text input in a template. This arose from the need to have all fields asking for a state to use autocomplete, so I decided to make this.
For disabling autocomplete and security purpose, this snippet defines a CharField with a randomness name for each request of the form. This is useful for turning off autocomplete for credit card input in all browsers, without breaking the xhtml validation. * [https://wiki.mozilla.org/The_autocomplete_attribute_and_web_documents_using_XHTML#Security](https://wiki.mozilla.org/The_autocomplete_attribute_and_web_documents_using_XHTML#Security) * [http://en.wikipedia.org/wiki/Cryptographic_nonce](http://en.wikipedia.org/wiki/Cryptographic_nonce)
This is a general JQuery Autocomplete Form Field for selecting any model instance in your forms. 1 Download jquery.1.2.6 and the jquery autocomplete plugin http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/, place theme somewhere in your media directory (in this case {{ MEDIA__URL}}/js/ 2 copy fields.py to anywhere in your python-path (in this case utils.fields) 3 create a view for the ajax request that receives a query and returns a key|value list, and register it in your urls.py 4 Just Use the fields in any form like in forms.py
This snippet allows you to use YUI's autocomplete widget in a easy way. 1. Download YUI (http://developer.yahoo.com/yui/) library and put it into MEDIA folder (in my case I put YUI/build/ directory as base/yui/ in my MEDIA folder) 2. Create lookup view for your autocomplete field. See 'test_ajax_ac' function to see how this lookup view may be built. You have to define JsonResponse somewhere in your files. JsonResponse is taken from: http://www.djangosnippets.org/snippets/154/ 3. Define url for newly created view in urls.py (in usual way) 4. Include necessary .js and .css files in your page (see example in test_ajax.html) 5. Assign widget to a field - see form's __init__ at UserForm in the example. Additional (optional) parameters are: format_result_fname (name of javascript function for formatting results - see YUI docs for examples)), item_select_handler_fname (name of javascript function for handling item select event (see YUI docs)). When using YUI take care about proper skin - you'll possibly need to define wrapper like: `<div class="yui-skin-sam">....</div>` around your html code.
This is an improvement of snippet 253 in that it supports database queries. Implementing autocompletion for foreign keys takes a few steps: 1) Put the snippet above into <app>/widgets/autocomplete.py. 2) Create a view of your foreign key model (here: Donator) in <app>/donator/views.py: from models import Donator from widgets.autocomplete import autocomplete_response def autocomplete(request): return autocomplete_response( request.REQUEST['text'], Donator, ( 'line_1', 'line_2', 'line_3', 'line_4', 'line_5', 'line_6', 'line_7', 'line_8', '^zip_code', 'location' ) ) This view returns the autocompletion result by searching the fields in the tuple. Each word from the form field must appear at least in one database field. 3) Create a URLconf that points to this new view. 4) In the form where you need the autocompletion, define the widget of the foreign key field as an instance of AutoCompleteField: from widget.autocomplete import AutoCompleteField field.widget = AutoCompleteField( url='/donator/autocomplete/'), options={'minChars': 3} ) The url parameter is the URL connected to the view in step 3), the options dict is passed on to the Ajax.Autocompleter JavaScript object.
