如何将值从mysql传递到创建视图中的表单字段

Question

我有一个 PatientConsultationView，其中有一个 createview 类创建，一个 AllConsultationView 列出所有咨询。我想将咨询 ID 传递给 PatientObservationView 并使用它来填充 PatientObservationForm 或者，只需将其保存在 PatientObservation 模型中，最终用户无需手动输入 ID，因为它可以从 AllConsultationView 获取

views.py

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.py

class PatientConsultationForm(forms.ModelForm):

    class Meta:

        model = PatientConsultation
        fields = ('patient_id', 'weight', 'temperature', 'blood_pressure', 'pulse', 'oxygen_saturation',
                  'body_mass_index', 'status',)

        widgets = {
            'patient_id': forms.Select(attrs={'class': 'form-control input-height', 'placeholder': 'Patient ID'}),
            'weight': forms.TextInput(attrs={'class': 'form-control input-height', 'placeholder': 'Patient Weight'}),

            'status': forms.Select(attrs={'class': 'form-control input-height', 'placeholder': 'Patient Status',}),
        }


class PatientObservationForm(forms.ModelForm):

    class Meta:

        model = PatientObservation

        widgets = {

Answer 1

您可以使用Models and request.user 下的modelform 文档中描述的技术从request kwargs 中设置咨询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)

（这里有点愚蠢的属性名称是因为你调用了ForeignKey字段consultation_id而不是consultation，所以底层的db列是consultation_id_id。你真的不应该那样做。）

请注意，您还需要从表单和模板的字段列表中删除 consultation_id，否则它将永远无效。
