Dynamically disable the autocomplete feature

[Domenico Testa]

Any chances to dynamically change the input behaviour using javascript?
I would like to "deactivate" the input changing it into a normal text field. Any suggestions?

Thanks in advance.

Yes you can deactivate the autocompletion with the destroy method inherited from the base jQuery UI plugin: http://api.jqueryui.com/autocomplete/#method-destroy

$('#field_id').djselectable('destroy');

Likewise you can change any of the options using option: http://api.jqueryui.com/autocomplete/#method-option

Let me give you some more context.

I have a django form with some AutoCompleteSelectField. Some of them are chained with the "prepareQuery" technique.

After form validation i save in the django model a string coming from the lookup item, not a model instance.

When i select a particular value on a master AutoCompleteSelectField i need to disable autocompletion on the dependant field and enabling free text input.
I don't need to create new lookup values, i just need that field behave like a normal CharField.
Now, if i call djselectable.option("option", "allowNew", true) i can input freely the text i want, but the hidden field is not synced with the text input, causing a missing required field validation error on the server side.

Could you suggest me a "right" approach?

If you aren't selecting a model instance then AutoCompleteSelectField doesn't seem like the appropriate field to use. Instead the form should just have a CharField and use the AutoCompleteWidget.

I've managed to replace the AutoCompleteField with a CharField(widget=AutoCompleteWidget...). Then i used .djselectable('option', 'disabled', true) in Javascript to disable autocomplete as needed.

Great package, thank you.
