Как реализовать каскадное сохранение?

Question

[Konstantin Malyarov]

Есть 3 модели, ПАЦИЕНТ, ПОЛИС, ПАСПОРТ.

Code1

from django.db import models

# Create your models here.

class Patient (models.Model):
    surName = models.CharField(max_length=100)
    firstName = models.CharField(max_length=100)
    secondName = models.CharField(max_length=100)
    dateOfBirth = models.DateField()

class InsurancePolicy (models.Model):
    id_patient = models.ForeignKey(Patient, on_delete=models.CASCADE)
    surName = models.CharField(max_length=100, blank=True, null=True)
    firstName = models.CharField(max_length=100, blank=True, null=True)
    secondName = models.CharField(max_length=100, blank=True, null=True)
    dateOfBirth = models.DateField(blank=True, null=True)
    validity = models.DateField(blank=True, null=True)
    insuranceDate = models.DateField(blank=True, null=True)
    insuranceOffice = models.TextField(max_length=250, blank=True, null=True)

class Passport (models.Model):
    id_patient = models.ForeignKey(Patient, on_delete=models.CASCADE)
    serialPassport = models.CharField(max_length=10, blank=True, null=True)
    numberPassport = models.CharField(max_length=10, blank=True, null=True)
    passportOffice = models.TextField(blank=True, null=True)
    passportEmit = models.DateField(blank=True, null=True)
    passportOfficeCode = models.CharField(max_length=30, blank=True, null=True)
    surName = models.CharField(max_length=100, blank=True, null=True)
    firstName = models.CharField(max_length=100, blank=True, null=True)
    secondName = models.CharField(max_length=100, blank=True, null=True)
    dateOfBirth = models.DateField(blank=True, null=True)
    region = models.CharField(max_length=100, blank=True, null=True)
    station = models.CharField(max_length=100, blank=True, null=True)
    district = models.CharField(max_length=100, blank=True, null=True)
    street = models.CharField(max_length=100, blank=True, null=True)
    home = models.CharField(max_length=30, blank=True, null=True)
    housing = models.CharField(max_length=30, blank=True, null=True)
    flat = models.CharField(max_length=30, blank=True, null=True)

Есть три формы, на основе моделей:

Code2

from django import forms
from .models import *


class addPatient(forms.ModelForm):
    surName = forms.CharField(widget=forms.TextInput(
        attrs={'class': 'btn btn-sm btn-outline-primary bg-light text-dark', 'style': 'text-align: left',

    class Meta:

        fields = '__all__'
        exclude = ['']


class addPassport(forms.ModelForm):
    serialPassport = forms.CharField(widget=forms.TextInput(
        attrs={'class': 'btn btn-sm btn-outline-primary bg-light text-dark', 'style': 'text-align: left'}), required=False)
    numberPassport = forms.CharField(widget=forms.TextInput(

    flat = forms.CharField(widget=forms.TextInput(
        attrs={'class': 'btn btn-sm btn-outline-primary bg-light text-dark', 'style': 'text-align: left'}), required=False)

    class Meta:
        model = Passport
        fields = '__all__'
        exclude = ['']

Как сохранить форму с взаимосвязью?

Code3

from django.shortcuts import render
from .forms import *

# Create your views here.
def index (request):
    formAddPatient = addPatient(request.POST or None)
    formAddInsurancePolicy = addInsurancePolicy(request.POST or None)
    formAddPassport = addPassport(request.POST or None)
    if request.method == 'POST' or formAddPatient.is_valid() or formAddInsurancePolicy.is_valid() or formAddPassport.is_valid():
        print(formAddPatient)
        print(formAddInsurancePolicy)
        print(formAddPassport)
        print(formAddPatient.cleaned_data)
        print(formAddInsurancePolicy.cleaned_data)
        print(formAddPassport.cleaned_data)
        dataAddPatient = formAddPatient.save()

    return render(request, 'patient/index.html', locals())

Может Вы разобьёте заполнение трёх форм на три этапа и будете сохранять промежуточные данные (первых двух форм) в сессии пользователя?

Answer 1

[JonGalt]

Сначала сохраняете форму пациента
dataAddPatient = formAddPatient.save()
Потом просто создаете InsurancePolicy и Passport не через сохранение формы, а вытаскиваете данные cleaned_data из сооветствующей формы и создаете новую запись.

surName = formAddInsurancePolicy.cleaned_data['surName']
...
newPolicy = InsurancePolicy(surName=surName, ... , id_patient=dataAddPatient)
newPolicy.save()
