My views.py
And I don't know whether my method is correct or not but I want to save the data from the raw HTML form only since I have to do some front end validation using java script.
from django.shortcuts import render
from .models import TimesheetDetails
# Create your views here.
def create_timesheet_view(request):
if request.method=="POST":
if(request.POST.get('dateToday') and request.POST.get('dayToday') and request.POST.get('startTime')
and request.POST.get('endTime')and request.POST.get('breakTime')and request.POST.get('normalTime')
and request.POST.get('overTime')and request.POST.get('holidayTime')and request.POST.get('weekType')
and request.POST.get('attendance')and request.POST.get('content')):
post = TimesheetDetails()
post.date = request.POST.get('dateToday')
post.day = request.POST.get('day_today')
post.startTime = request.POST.get('startTime')
post.endTime = request.POST.get('endTime')
post.breakTime = request.POST.get('breakTime')
post.normalTime = request.POST.get('normalTime')
post.overTime = request.POST.get('overTime')
post.holidayTime = request.POST.get('holidayTime')
post.weekType = request.POST.get('weekType')

if post.is_valid():
try:
post.save()
return render(request,'timesheet/view_timesheet.html')
except :
pass
else:
return render(request,'timesheet/create_timesheet.html')
def view_timesheet(request):
return render(request,"timesheet/view_timesheet.html")
my models.py
class TimesheetDetails(models.Model):
date = models.CharField(max_length = 10)
day = models.CharField(max_length = 10)
startTime = models.CharField(max_length =10)
endTime = models.CharField(max_length =10)
breakTime = models.CharField(max_length=3)
normalTime = models.CharField(max_length=10)

weekType = models.CharField( max_length = 10)

Welcome to SO :)
You're not returning a HttpResponse when post.is_valid() returns False.
from django.shortcuts import render
from .models import TimesheetDetails
# Create your views here.
def create_timesheet_view(request):
if request.method=="POST":
if(request.POST.get('dateToday') and request.POST.get('dayToday') and request.POST.get('startTime')
and request.POST.get('endTime')and request.POST.get('breakTime')and request.POST.get('normalTime')
and request.POST.get('overTime')and request.POST.get('holidayTime')and request.POST.get('weekType')
and request.POST.get('attendance')and request.POST.get('content')):
post = TimesheetDetails()
post.date = request.POST.get('dateToday')
post.day = request.POST.get('day_today')
post.startTime = request.POST.get('startTime')
post.endTime = request.POST.get('endTime')
post.breakTime = request.POST.get('breakTime')
post.normalTime = request.POST.get('normalTime')
post.overTime = request.POST.get('overTime')
post.holidayTime = request.POST.get('holidayTime')
post.weekType = request.POST.get('weekType')
post.attendance = request.POST.get('attendance')
post.content = request.POST.get('content')
if post.is_valid():
try:
post.save()
return render(request,'timesheet/view_timesheet.html')
except :
pass
else:
return render(request,'timesheet/create_timesheet.html') #Adding this line
else:
return render(request,'timesheet/create_timesheet.html')
def view_timesheet(request):
return render(request,"timesheet/view_timesheet.html")
