Galvenā problēma ir tā, ka Django izvelk masīvu no pasta matricas kā Python sarakstu, nevis kā NumPy masīvu. Tas var radīt problēmas, ja jums ir jāveic jebkāda veida matemātiskas darbības ar masīvu, jo NumPy masīvi ir daudz efektīvāki šāda veida darbam.
Manā HTML lapā ir matrica, kuru ievietoju savā Django skatā. Matrica ir sarakstu saraksts, un es vēlos izvilkt atsevišķus sarakstus no ievietotajiem datiem. Kā es to varu izdarīt?
Lūk, kas man ir līdz šim:
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, Man ir izvēles rūtiņu matrica, kas izskatās šādi:
<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 , "
