主要问题是 Django 从 post 矩阵中提取数组作为 Python 列表，而不是作为 NumPy 数组。 如果您需要对数组进行任何类型的数学运算，这可能会导致问题，因为 NumPy 数组对于此类工作的效率要高得多。
我在我的 HTML 页面中有一个矩阵，我正在发布到我的 Django 视图。 矩阵是列表列表，我想从发布的数据中提取单个列表。 我怎样才能做到这一点？
这是我到目前为止的内容：
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，我有一个复选框矩阵，如下所示：
<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 , "
