Question

在我的健康应用中，我试图让用户输入患者症状数据并保存。

我的应用包含Identity，Symptom和IdentitySymptom型号。

在Identity和Symptom之间存在ManyToManyField。

IdentitySymptom模型包含两个引用Identity和Symptom模型的ForeignKey字段。

在我的视图文档中，我使用了基于类的视图来确保我创建的每个症状对象都附加到患者身上。

问题：每次创建Symptom对象并单击以保存它时，都会返回以下错误：

我已经从Identity模型创建了患者对象。

class Identity(models.Model):

    NIS =models.CharField(max_length = 200, primary_key = True)
    user = models.ForeignKey(settings.AUTH_USER_MODEL)
    time_patient_creation = models.DateTimeField(auto_now = True)
    first_name = models.CharField(max_length = 80, null = True)
    last_name = models.CharField(max_length = 80, null = True )
    contact = models.CharField(max_length = 15, null = True)
    location  = models.CharField(max_length = 100, blank = True)
    born = models.DateField(auto_now = False, auto_now_add = False, blank = True, null = True)

    patient_key = models.ManyToManyField('Symptom')

我还从Symptom模型

创建了Symptom对象

我还创建了一个包含IdentitySymptom字段

的ForeignKey模型

class IdentitySymptom(models.Model):

    identity = models.ForeignKey(Identity)
    key_medical = models.ForeignKey(Symptom)

这是我的观看文档，包含基于类的视图

from django.shortcuts import render, redirect
from django.views.generic import CreateView, ListView
from script.forms import  IdentityForm, MedicalForm


from script.models import Identity, Symptom, IdentitySymptom





class Identity_view(CreateView):


    model = Identity

    template_name = 'script/script.html'


    def get(self, request):



        form = IdentityForm()


        script = Identity.objects.filter(user = request.user)


        var = {'form':form, 'script':script}


        return render(request, self.template_name, var)


    def post(self, request):

        form = IdentityForm(request.POST)


        being = None



        if form.is_valid():


            NIS = form.save(commit = False)
            #
            NIS.user = request.user

            NIS.save()


            being = form.cleaned_data['NIS']

            form = IdentityForm()

            return redirect('script:script')

        var = {'form': form, 'being':being }


        return render(request, self.template_name, var)


class Identity_list_view(ListView):

    model = Identity

    template_name = 'script/identity_list.html'

    def get(self, request):

        form = IdentityForm()

        script = Identity.objects.filter(user = request.user)

        var = {'form':form, 'script':script}
        return render(request, self.template_name, var)


class Medical_document(CreateView):

    model = Symptom

    template_name = 'script/medical_document.html'

    def get(self, request, pk):

        form = MedicalForm

        script = Symptom.objects.all()
        var = {'form':form, 'script':script, 'pk':pk}

        return render(request, self.template_name, var)


    def post(self, request, pk):




        form = MedicalForm(request.POST)

        state = None

        if form.is_valid():



            manuscript = form.save(commit = False)

            manuscript.user = request.user


            state = form.cleaned_data['description']


            manuscript.save()





            patient = Identity.objects.get(pk=pk)

            medical_key = IdentitySymptom.objects.create(patient = patient, manuscript = manuscript)

            medical_key.patient.patient_key.add(manuscript)

            form = MedicalForm()

            redirect('script:script')

        else:
            print(form.errors)

        var = {'form': form, 'state': state, 'pk':pk}

        return render(request, self.template_name, var)

Answer 1

这一行

medical_key = IdentitySymptom.objects.create(patient = patient, manuscript = manuscript)

引发错误，因为IdentitySymptom没有稿件字段。

根据您的定义，

class IdentitySymptom(models.Model):

    identity = models.ForeignKey(Identity)
    key_medical = models.ForeignKey(Symptom)

您只能指定identity和key_medical。

我可以看到patient是Identity个实例，假设稿件是Symptom，那么你真的想做

medical_key = IdentitySymptom.objects.create(identity = patient, key_medical = manuscript)

TypeError：＆＃39;手稿＆＃39;是此函数的无效关键字参数
