如何從url到表單的方法獲取一個變量 - 保存？

Question

我已經URLPATTERN ID爲

... 
url(r'^3/(?P<id>[-\w]+)', Biochemical_analysis_of_blood.as_view(),\ 
    name='biochemical_analysis_view'), 
... 

views.py

class Biochemical_analysis_of_blood(CreateView): 
    model = BiochemicalAnalysisOfBlood 
    form_class = BiochemicalAnalysisOfBloodForm 
    template_name = "biochemical_analysis_of_blood.html" 
    success_url = reverse_lazy("patients") 

    def get_context_data(self, **kwargs): 
     context = super(Biochemical_analysis_of_blood, self).get_context_data(**kwargs) 
     context["patient"] = Patient.objects.get(id=self.kwargs['id']) 
     context["caption"] = 'Біохімічний аналіз крові' 
     context["new"] = True 
     return context 

forms.py

class SaveForms(): 
    def save(self, commit=True): 
     analysis = Analyzes() 
     sid = transaction.savepoint() 
     analysis.name = self.data["name"] 
     analysis.patient_id = Patient.objects.get(id=1) 
     analysis.who_send = self.data["who_send"] 
     analysis.who_is_doctor = self.data["who_is_doctor"] 
     analysis.lab_user_id = Doctor.objects.get(id=self.data["lab_user_id"]) 
     analysis.additional_lab_user = self.data["lab_user_add"] 
     analysis.date = self.data["date"] 
     analysis.type = 3 
     analysis.date_analysis = self.data["date_analysis"] 
     analysis.save() 
     # Your analysis is created, attach it to the form instance object 
     self.instance.analysis_id = analysis.id 
     return super().save(commit) 

我怎樣才能從URL變量 「ID」 來形成的方法 - 保存？類SaveForms將由其他forms.models類執行，因爲它們都必須具有相同的保存方法。

... 
    analysis.patient_id = Patient.objects.get(id=1) 
... 

改爲「1」我必須使用url中的「id」...誰能幫助我？

class BiochemicalAnalysisOfBloodForm(SaveForms, forms.ModelForm): 
...

您可以在您的形式存取權限請求數據，檢查這個答案：

How do I access the request object or any other variable in a form's clean() method?

的request.user對象，而不是採取Request的。
