Question

我有一份报告表单report.html：

<select id="select" class="form-control" name="organization">
        <option value="">-- Select Organization --</option>
        {% for organization in organization_list %}
        <option value="{{ organization.name }}">{{ organization.name }}</option>
        {% endfor %}
</select>

提交此表单后，不会保存所选组织。但如果组织将被展示会更好。它对用户有用：她/他可以看到，哪些过滤器显示这些结果。

如何在表单提交选择字段的选定值后保存并显示？

views.py：

def report(request):

    user = request.user
    admin = None
    try:
        admin = user.administrator
    except ObjectDoesNotExist:
        pass
    if not admin:
        return render(request, 'vms/no_admin_rights.html')

    organization_list = get_organizations_ordered_by_name()

    if request.method == 'POST':
        form = ReportForm(request.POST)
        if form.is_valid():
            first_name = form.cleaned_data['first_name']
            last_name = form.cleaned_data['last_name']
            organization = form.cleaned_data['organization']
            event_name = form.cleaned_data['event_name']
            job_name = form.cleaned_data['job_name']
            start_date = form.cleaned_data['start_date']
            end_date = form.cleaned_data['end_date']
            report_list = get_administrator_report(
                first_name,
                last_name,
                organization,
                event_name,
                job_name,
                start_date,
                end_date
                )
            total_hours = calculate_total_report_hours(report_list)
            return render(request, 'administrator/report.html', {'form': form, 'report_list': report_list, 'total_hours': total_hours, 'notification': True, 'organization_list': organization_list})
        else:
            return render(request, 'administrator/report.html', {'form': form, 'notification': False, 'organization_list': organization_list})
    else:
        form = ReportForm()
        return render(request, 'administrator/report.html', {'form': form, 'notification': False, 'organization_list': organization_list})

forms.py：

class ReportForm(forms.Form):
    first_name = forms.RegexField(regex=r'^[(A-Z)|(a-z)|(\s)]+$', max_length=30, required=False)
    last_name = forms.RegexField(regex=r'^[(A-Z)|(a-z)|(\s)]+$', max_length=30, required=False)
    organization = forms.RegexField(regex=r'^[(A-Z)|(a-z)|(\s)]+$', max_length=75, required=False)
    event_name = forms.RegexField(regex=r'^[(A-Z)|(a-z)|(0-9)|(\s)|(\.)|(,)|(\-)|(!)]+$', max_length=75, required=False)
    job_name = forms.RegexField(regex=r'^[(A-Z)|(a-z)|(\s)]+$', max_length=75, required=False)
    start_date = forms.DateField(required=False)
    end_date = forms.DateField(required=False)

更改此行：

 <input type="button" id="btnOpenDialog" value="Open Confirm Dialog" />
    <div id="dialog-confirm"></div>
<script>
function fnOpenNormalDialog() {
    $("#dialog-confirm").html("Confirm Dialog Box");

    // Define the Dialog and its properties.
    $("#dialog-confirm").dialog({
        resizable: false,
        modal: true,
        title: "Modal",
        height: 250,
        width: 400,
        buttons: {
            "Yes": function () {
                $(this).dialog('close');
                callback(true);
            },
                "No": function () {
                $(this).dialog('close');
                callback(false);
            }
        }
    });
}

$('#btnOpenDialog').click(fnOpenNormalDialog);

function callback(value) {
    if (value) {
        alert("Confirmed");
    } else {
        alert("Rejected");
   }
} </script>

添加到上下文return render(request, 'administrator/report.html', {'form': form, 'report_list': report_list, 'total_hours': total_hours, 'notification': True, 'organization_list': organization_list})：

'selected_organization': organization

报告表格应如下所示：

return render(request, 'administrator/report.html', {'form': form, 'report_list': report_list, 'total_hours': total_hours, 'notification': True, 'organization_list': organization_list, 'selected_organization': organization})
