目前，我正在构建一个由 django 驱动的 Web 应用程序，用于从主表中显示过滤后的数据。我创建了一个表单，用户将在其中指定他/她的选择，并根据表单值数据（以表格形式）显示。我的问题是我无法从需要多个值的表单字段中获取数据。我正在使用“request.POST.get('fieldname','') 从表单中获取数据，但是对于多个值字段，它正在显示最后一个值。
示例： 如果用户在表单域“模块”中选择第一个、第二个和第四个选项，
request.POST.get('模块','')
只给我第四个选择。我希望我清楚自己。
视图.py
def consisreportgen(request):
if request.method == 'POST':
form = ConsistencyForm(request.POST or None)
if form.is_valid():
form_user_data = ConsistencyForm(request.POST)
Customer=form.cleaned_data['Customer']
Components=form.cleaned_data['Components']
Modules=form.cleaned_data['Modules']
customername=request.POST.get('Customer','')
modules_choosen=request.POST.get('Modules','')
bpc_choosen=request.POST.get('Components','')
severity=request.POST.get('Severity_level','')
print(modules_choosen)
print(customername)
print(severity)
print(bpc_choosen)
return HttpResponseRedirect('/consistency/results/')
else:
form = ConsistencyForm
return render(request,'consistency/consistency.html', {'form': form})
表格.py
class ConsistencyForm(forms.Form):
Customer=forms.ModelChoiceField(
label="Customer Name",
widget=forms.Select,
queryset=Customer.objects.all(),
empty_label=None,
)
Severity_level=forms.ModelChoiceField(
label="Severity Level",
widget=forms.Select,
queryset=Criticality.objects.all(),
empty_label=None,
)
query_status=forms.ModelChoiceField(
widget=forms.Select,
label="Query Status",
queryset=Status.objects.all(),
empty_label=None,
help_text="</br>"
)
Modules=forms.ModelMultipleChoiceField(
label="Business Module",
widget=forms.CheckboxSelectMultiple,
queryset=Modules.objects.all(),
)
Components=forms.ModelMultipleChoiceField(
widget=forms.CheckboxSelectMultiple,
queryset=Component.objects.all(),
)
