我正在模板中使用选择标签以及在表单标签内具有“提交”类型的链接。当我从下拉菜单中选择一个选项并单击按钮时,它会转到下一页,但是我无法获取所选选项的值。其显示的AttributeError'Manager'对象没有属性'month'。这是我的代码:
<form method="POST" action="{% url 'results' %}">
{% csrf_token %}
<select name="mahina" id="month">
<option value="all">All</option>
<option value="jan">January</option>
<option value="feb">February</option>
</select>
<a href="{% url 'results' %}" type="submit">Search</a>
</form>
这是我的观点。py
from django.shortcuts import render
from .models import Results
def allresults(request):
results = Results.objects
if request.method == "GET":
month = results.month
year = results.year
return render(request, 'results/allresults.html', {'results': results}
答案 0 :(得分:1)
因此,要在视图中获取表单值,您必须像form_val = request.GET.get('field_name', <default_value>)
一样,以便在代码中添加几行
def allresults(request):
# this will get the value of the selected item, print this to know more
mahina = request.GET.get('mahina', None)
#Just writing the below query field month randomly, since the models isn't posted
results = Results.objects.filter(month=mahina)
# We don't need to give GET since by default it is a get request
# Since there are multiple objects returned, you must iterate over them to access the fields
for r in results:
month = r.month
year = r.year
return render(request, 'results/allresults.html', {'results': results}
