Django: using <select multiple> and POST

问题:

I'm using something like this in my template

<select multiple="multiple"  name="services" id="services" size="5">
    {% for service in services %}
        <option value="{{service.id}}">{{service}}</option>
    {% endfor %}
</select>

When I view the POST data in Firebug or the Django debug, I see it only sends one value. Am I doing something wrong or misunderstanding a concept?

回答1:

request.POST.getlist('services')

回答2:

Just FYI, I had to use:

    list = request.POST.getlist("items[]")

because omitting the [] caused a blank list to be returned instead of the correct values. I'm using jQuery to fetch the values of a multiple select element, and jQuery appears to be adding the []

Watch out! getlist method from QueryDict returns an empty list if the key doesn't exist. It does not throw an exception. http://bit.ly/MdgrUH

回答4:

you can get the expected list just by using...

request.POST.getlist('fiel_name')

回答5:

request.POST.getlist('services')

Worked for me. or you can define select box name as a list
