Peamine probleem seisneb selles, et Django ekstraheerib massiivi postimaatriksist Pythoni loendina, mitte NumPy massiivina. See võib põhjustada probleeme, kui peate massiiviga mingeid matemaatilisi toiminguid tegema, kuna NumPy massiivid on sellise töö jaoks palju tõhusamad.
Minu HTML-lehel on maatriks, mille postitan oma Django vaatesse. Maatriks on loendite loend ja ma tahan postitatud andmetest eraldada üksikud loendid. Kuidas ma saan seda teha?
Siin on see, mis mul siiani on:
def myview(request):
if request.method == 'POST': # If the form has been submitted...
form = MyForm(request.POST) # A form bound to the POST data
if form.is_valid(): # All validation rules pass
# Process the data in form.cleaned_data
return HttpResponseRedirect('/thanks/') # Redirect after POST
else:
form = MyForm() # An unbound form
return render(request, 'mytemplate.html', {'form':form})
In mytemplate.html, mul on märkeruutude maatriks, mis näeb välja selline:
<table><tr><td>1,1 <input type="checkbox" name="matrix[0][0]" value="1" /> </td> <td> 1,2 <input type="checkbox" name="matrix[0][1]" value="1" />" </td>" <"td"="" 1,3="" "="" input="" type="checkbox" name=matrix[0][2] value=1 /"" ""="" td="" tr="" table="" xtml-space:"preserve"" xmlns:xtml-space="http://www." w3corg/xml/1998/namespace"" xmlns_w3corg="/xmlns/" xml:"lang=en-us"" lang=en-us"" http://www."" w3corg/1999xhtml"" xmlns_w3corg="/1999/" html:"xmlns=http://www."" w3corg/" lang=en-us""" class="container">2,1 &"nbsp;" 2,2 "nbsp;" 2," 3 "nbsp;" 3," 1 "nbsp;" 3," 2 "nbsp;" 3," 3 "nbsp;" 4," 1 "nbsp;" 4," 2 "nbsp;" 4," 3 "" nbsp ; "" 5 , "" 1 "" nbsp ; "" 5 , "" 2 "" nbsp ; "" 5 , """ 6 ," """ 7 ," """ 8 ," """ 9 ," """ 10 ," """ 11 ," """ 12 ," """ 13 ," """ 14 , "
