篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了如何将值从mysql传递到create视图中的表单域相关的知识,希望对你有一定的参考价值。

我有一个带有创建的createview类的PatientConsultationView,以及一个列出所有咨询的AllConsultationView。我想将咨询ID传递给PatientObservationView并使用它填充PatientObservationForm OR,只是将其保存在PatientObservation模型中,而最终用户无法手动输入ID,因为它可以从AllConsultationView获取

views.朋友

class PatientConsultationView(CreateView):
    model = PatientConsultation
    template_name = 'patient/patient_consultation_add.html'
    form_class = PatientConsultationForm
    context_object_name = 'Patient_Consultation'
    success_url = reverse_lazy('patient_list')

class AllConsultationView(ListView):
    model = PatientConsultation
    template_name = 'patient/all_consultation.html'
    context_object_name = 'All_Patient_Consultation'

    def get_consult_id(self):

        return PatientConsultation.objects.filter(consultation_id=self)

class PatientObservationView(CreateView):
    model = PatientObservation
    template_name = 'patient/patient_observation_add.html'
    form_class = PatientObservationForm
    context_object_name = 'Patient_Observation'
    success_url = reverse_lazy('patient_list')

forms.朋友

                  'body_mass_index', 'status',)

        widgets = {

答案

您可以使用Models and request.user下的modelform文档中描述的技术来设置请求kwargs中的咨询ID。

class PatientObservationView(CreateView):
    ...
    def form_valid(self, form):
        form.instance.consultation_id_id = self.kwargs['consultation_id']
        return super(PatientObservationView, self).form_valid(form)

(这里稍微愚蠢的属性名称是因为你已经调用了你的ForeignKey字段consultation_id而不是consultation,所以底层的db列是consultation_id_id。你真的不应该这样做。)

另请注意,您需要从表单中的字段列表以及模板中删除consultation_id,否则它将永远无效。
