Question

I am new to python and django and was wondering how I would go about making a dict of lists.

My 4 lists are;

ap = request.POST.getlist('amount_paid[]')
pd = request.POST.getlist('paid_date[]')
method = request.POST.getlist('method[]')
comments = request.POST.getlist('comments[]')

How would I make that into a dictionary I could then loop over in a django template such as;

{% for i in the_dict %}
{{i.amount_paid}}
{% endfor %}

Thanks in advance!

Update:

hmm I not sure I posted my question properly. In php, I can do the following on an array of fields:

for($i=0;$i<count($_POST['amount_paid']);$i++) {
echo $_POST['amount_paid'][$i];
echo $_POST['paid_date'][$i];
}

All the form fields are input text fields.. How would I do this in Django?

Answer 1

Python’s dict syntax is very simple. It’s just key-value pairs inside a pair of curly braces, like this:

the_dict = {
    'amount_paid': request.POST.getlist('amount_paid[]'),
    'paid_date': request.POST.getlist('paid_date[]'),
    'method': request.POST.getlist('method[]'),
    'comments': request.POST.getlist('comments[]'),
}

Following your update, it looks like you don’t want a dict at all but zip():

post = request.POST
lists = zip(post.getlist('amount_paid[]'), 
        post.getlist('paid_date[]'),
        post.getlist('method[]'),
        post.getlist('comments[]'),
        )
for amount_paid, paid_date, method, comments in lists:
    print amount_paid
    print paid_date
    # et cetera...
