我正在开发一个django项目，模型CaseRegister我试图使用模型表单提交值。我的模特班belo
- model.py
from django.db import models
from core.models import ProviderMaster,FacilityMaster,ProviderMaster,CaseMaster,CasestatusMaster
from patient.models import PatientMaster
from django.contrib.auth.models import User
from django.forms import ModelForm
from account.models import Profile
def update_id(func):
def decorated_function(*args):
data_object = args[0]
sequence_name = 'seq_%s' % data_object._meta.db_table
from django.db import connection
cursor = connection.cursor()
cursor.execute("SELECT nextval(%s)", [sequence_name])
row = cursor.fetchone()
data_object.caseid = row[0]
return func(*args)
return decorated_function
class CaseRegister(models.Model):
caseid = models.DecimalField(primary_key=True, max_digits=8, decimal_places=0)
patient = models.ForeignKey(PatientMaster, on_delete=models.CASCADE, db_column='patientid')
case_startdate = models.DateField()
case_enddate = models.DateField(blank=True, null=True)
providerid = models.ForeignKey(ProviderMaster, models.DO_NOTHING, db_column='providerid', blank=True, null=True)
facilityid = models.ForeignKey(FacilityMaster, models.DO_NOTHING, db_column='facilityid', blank=True, null=True)
casetypeid = models.ForeignKey(CaseMaster, models.DO_NOTHING, db_column='casetypeid', blank=True, null=True)
casestatus = models.ForeignKey(CasestatusMaster, models.DO_NOTHING, db_column='casestatus', blank=True, null=True)
approved_date = models.DateField(blank=True, null=True)
last_modifieduser = models.ForeignKey(Profile,on_delete=models.CASCADE, db_column='last_modifieduser')
class Meta:
managed = False
db_table = 'case_register'
def __str__(self):
return self.caseid
@update_id
def save(self):
# Now actually save the object.
super(CaseRegister, self).save()
表单创建如下，并为所有FK字段设置映射查询
- The form.py
from django import forms
from .models import CaseRegister
from patient.models import PatientMaster
from django.contrib.auth.models import User
from account.models import Profile,ProfileFaciltiyMembership
from core.models import FacilityMaster,CasestatusMaster,ProviderMaster,ProviderCategory,RoleMaster
from django.db.models import Q
import datetime
class CaseRegisterForm(forms.ModelForm):
class Meta:
model = CaseRegister
fields = ('caseid', 'patient', 'case_startdate',"case_enddate","facilityid","providerid","casetypeid","casestatus","last_modifieduser" )
def __init__(self, p,profile,request, *args, **kwargs):
super(CaseRegisterForm, self).__init__(*args, **kwargs)
print("request.method "+request.method)
if (request.method=='GET'):
print("request.method "+request.method)
self.fields['patient'].empty_label = None
self.fields['patient'].label="Patient"
self.fields['patient'].queryset = PatientMaster.objects.filter(patientid=p.patientid)
self.fields['patient'].widget.attrs = {'maxlength': 10}
self.fields['patient'].widget.attrs = {'disabled': True}
self.fields['case_startdate'].widget.attrs = {'class': 'vDateField'}
self.fields['case_startdate'].label="Date"
self.fields['case_startdate'].initial=datetime.datetime.now().date()
#self.fields['last_modifieduser'].queryset = Profile.objects.filter(user=profile.user)
self.fields['last_modifieduser'].queryset = Profile.objects.all()
self.fields['last_modifieduser'].empty_label = None
#self.fields['last_modifieduser'].widget = forms.HiddenInput()
self.fields['caseid'].required = False
self.fields['caseid'].widget = forms.HiddenInput()
self.fields['case_enddate'].widget = forms.HiddenInput()
fid = request.session["currfacility"]
self.fields['facilityid'].empty_label = None
self.fields['facilityid'].queryset = FacilityMaster.objects.filter(facilityid=fid)
self.fields['facilityid'].widget.attrs = {'disabled': True}
self.fields['casestatus'].empty_label = None
self.fields['casestatus'].queryset=CasestatusMaster.objects.filter(casestatusid=1)
facility=FacilityMaster.objects.get(pk=fid)
profiles=Profile.objects.filter(facilities=facility)
providercat = ProviderCategory.objects.get(pk=2)
self.fields['providerid'].empty_label = None
self.fields['providerid'].label="Physician"
self.fields['casetypeid'].label="Type"
self.fields['casetypeid'].empty_label = None
self.fields['casestatus'].label="Status"
criterion1 = Q(profile__in=profiles)
criterion2 = Q(pcategoryid=providercat)
rid = request.session["currrole"]
print(rid)
if rid == str(2) :
print("if")
profile = request.user.profile
pfid = profile.provider.providerid
print(pfid)
criterion3 = Q(providerid=pfid)
self.fields['providerid'].queryset = ProviderMaster.objects.filter(criterion3 & criterion2)
else:
print("else")
self.fields['providerid'].queryset = ProviderMaster.objects.filter(criterion1 & criterion2)
下面是视图，在GET方法中，我正在分配患者ID和 POST请求我没有对模型进行任何操作 - view.py
from django.shortcuts import render,redirect
from .forms import CaseRegisterForm
from .models import CaseRegister
from patient.models import PatientMaster
from django.contrib import messages
from django.contrib.auth.mixins import LoginRequiredMixin
from django.views.generic import CreateView, DetailView, UpdateView
def caseregister(request):
pid =1413963
if request.method == "POST":
form = CaseRegisterForm(None,request.user.profile,request,request.POST)
#form = CaseRegisterForm(request.POST)
print(form.is_valid())
print(form.errors)
if form.is_valid():
model_instance = form.save(commit=False)
model_instance.save()
return redirect('{% url "createcase" %}')
else:
pid =1413963
p = PatientMaster.objects.get(pk=pid)
form = CaseRegisterForm(p,request.user.profile,request)
return render(request, "case_register.html", {'form': form})
提交表单时，我收到错误 - 患者 - 此字段是必填消息。 我尝试在post方法中映射查询集患者，就像get一样。我收到同样的错误。
