                for (var field in errors) {
                    var id_field = '#id_' + field;
                    $(id_field).parent().parent().addClass('has-error');
                    $(id_field).after('<div class="help-block">' + errors[field][0] + '</div>\n');

};
toastr.options = {
            "closeButton": true,
            "debug": false,
            "progressBar": true,
            "preventDuplicates": true,

</script>

</form>

2、url檔案：

urlpatterns = [
    path('setting', setting.Setting.as_view(), name='setting'),

]

3、views檔案：

from django.contrib.auth.mixins import LoginRequiredMixin
from django.http import HttpResponse
from django.shortcuts import render
from django.views.generic import View
from sqlapply.forms import SettingForm
from sqlapply.models import GlobalConfig
import json

class Setting(LoginRequiredMixin, View):
    def get(self, request, *args, **kwargs):
        form = SettingForm()
        GlobalConfig.objects.all().first()
        return render(request, "sqlapply/setting.html", {"form": form})

    def post(self, request, *args, **kwargs):
        form = SettingForm(request.POST) 
        if form.is_valid():
            globalConfig = GlobalConfig()
            globalConfig.inception = form.cleaned_data
            globalConfig.save()
            response_data = {'statcode': '1', 'data': ''}
        else:
            response_data = {'statcode': '0', 'data': dict(form.errors)}
        return HttpResponse(json.dumps(response_data))
