python - 如何从下拉列表中选择多个值到views.py

Question

我正在使用以下代码:

index.html

<div class="col-sm-3" style="margin-left: 30px;">
            <select id="month" name="month" multiple>

                  <option value="01">January</option>
                  <option value="02">February</option>
                  <option value="03">March</option>
                  <option value="04">April</option>
                  <option value="05">May</option>
                  <option value="06">June</option>
                  <option value="07">July</option>
                  <option value="08">August</option>
                  <option value="09">September</option>
                  <option value="10">October</option>
                  <option value="11">November</option>
                  <option value="12">December</option>


            </select>
          </div>

Views.py

def internal(request):
   try:
       year = ''
       month = []
       year = request.GET.get('year')
       month = request.GET.get('month')
       print(month)
       response_list = []
   except Exception as e:
       print(str(e))
   return HttpResponse(json.dumps(response_list))

我在前端选择了多个值，但是当我在 views.py 中获取它时，只有一个选项被获取。如何获取从下拉列表中选择的所有值？

Answer 1

您需要使用 getlist(key) .

像这样:

month = request.GET.getlist('month')

get(key) 只会给你最后选择的值:

If the key has more than one value, it returns the last value.
