脆皮错误 |as_crispy_field 传递了一个无效或不存在的字段

Question

我想根据自己的需要自定义 django Model 字段并将数据提交到数据库中。 我相应地做了所有的事情。但是在运行该应用程序后，我得到了脆性错误。我无法找到我的错误。 请朋友们帮帮我。

Models.py如下

from django.db import models
from datetime import date
from configration.models import AddSite, AddDepartment, AddCategory, AddDesignation, Rate
# Create your models here.


class EmployeeRegistration(models.Model):
#Departmental Details

EmpId = models.IntegerField(verbose_name='EmpId')
Site = models.ForeignKey(AddSite,on_delete=models.CASCADE,max_length=150,verbose_name='Site')
Department = 
models.ForeignKey(AddDepartment,on_delete=models.CASCADE,max_length=150,verbose_name='Department')
Category = 
models.ForeignKey(AddCategory,on_delete=models.CASCADE,max_length=150,verbose_name='Category')
Designation = 
models.ForeignKey(AddDesignation,on_delete=models.CASCADE,max_length=150,verbose_name='Designation')
PfAllowance = models.BooleanField(default = True)
EsiAllowance = models.BooleanField(default = True)
Uan = models.PositiveIntegerField(null = False,verbose_name='Uan')
Pf = models.PositiveIntegerField(null = True,verbose_name='Pf')
AttendenceAward = models.BooleanField(default = True)
AttendenceAllowance = models.BooleanField(default = True)
ProfesionalTax = models.BooleanField(default = False)
Rate = models.PositiveIntegerField(null = True)
# Personal Details
Name = models.CharField(max_length=150,verbose_name='Name')
Father = models.CharField(max_length=150,verbose_name='Father')
Dob = models.DateField()
Gender = models.BooleanField(default = True)
#Female = models.BooleanField(default = False)
MaritalStatus = models.BooleanField(default = True)
Address = models.CharField(max_length=200,verbose_name='Address')
Aadhar = models.PositiveIntegerField(null=True)
pan = models.CharField(max_length=10)
choices = [('Working','WORKING'),('NotWorking','NOT WORKING')]
Status = models.CharField(choices=choices,blank = False,max_length=10,verbose_name='Status')
Doj = models.DateField(default = date.today)
Doe = models.DateField(blank = True,verbose_name = 'Doe',null = True)

def __str__(self):
    return '{name}'.format(name=self.Name)

views.py如下

from django.shortcuts import render
from .regform import regisForm
from django.http import HttpResponse
from configration.models import AddSite, AddCategory,Rate
from .models import EmployeeRegistration
# Create your views here.   
def ids():
   no = EmployeeRegistration.objects.count()
   if(no == None):
      number = 1
      return number
   else:
      number = no + 1
      return number

def registration_view(request,*args, **kwargs):
  emp_id = ids()
  EmployeeId={'EmpId':emp_id}
  form = regisForm(request.POST or None,initial=EmployeeId)
  print(form)
  if form.is_valid():
     form.save()
     form = regisForm()
  else:
     pass

  context = {
    'form':form,
    "contact":"active"
   }
return render(request,"registration.html",context)

registration.html如下

试试这个：

def registration_view(request,*args, **kwargs):
  emp_id = ids()
  EmployeeId={'EmpId':emp_id}
  form = regisForm(request.POST or None,initial=EmployeeId)
  print(form)
  if form.is_valid():
     form.save()

  else:
     return render(request,"registration.html",{"form": form, "contact":active})   #add this

  context = {
    "form":form,   #edit this
    "contact":active
   }
return render(request,"registration.html",context)
