Django: using <select multiple> and POST

Question

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?

What's the value of services that's provided to the template? — S.Lott

Do you mean: services = Service.objects.all() return render_to_response('add.html', {'services': services}) ?? (I cannot get these comments to format at all.) — neoice

@neoice: Hint: don't add details to your questions in the comments. Edit your question to add facts. The question always formats correctly. AND the question should stand by itself without a thread of comments. — S.Lott

Jackpot! I think I did need to change services to services[], but getlist r0xors for this. I thought I'd scoured the Django docs but apparently, I was wrong.

You don't need the []. That's a convention limited to PHP.

It might be worth mentioning that this also works for GET data. request.GET.getlist('services')

I needed to change services to services[] for Python as well.

May you expand where this should be? If I replace it in the View, then when debuging I get the list but lost all of the extra fields.

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 []

I have to use [] wihtout any blank between

electromechanick Over a year ago

Yeah, I originally had the brackets with no space between them, then somebody came along and edited my response to include a space, which of course breaks the code because matching a literal "[]" is not the same as "[ ]"

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

request.POST.getlist('fiel_name')

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
