problem with form

Hi

I'm trying to make a simple crud applicatio and learn from it. I wonder why my form can't save the data. Here cames my view:

from django.shortcuts import render

from saeed.forms import SmodelForm  

from saeed.models import Smodel

from django.shortcuts import render, redirect  

# Create your views here.

def emp(request):  

    if request.method == "POST":  

        form = SmodelForm(request.POST)  

        if form.is_valid():  

            try:  

                form.save()  

                return redirect('/show')  

            except  AssertionError as error:

                

                print(error)

                pass

     

                

                

    else:  

        form = SmodelForm()  

    return render(request,'saeed/index.html',{'form':form})  

#----------------------------------------

def show(request):  

    smodels = Smodel.objects.all()  

    return render(request,'saeed/show.html',{'smodels':smodels}) 

#----------------------------------------

def edit(request, id):  

    smodels = Smodel.objects.get(id=id)  

    return render(request,'saeed/edit.html', {'smodels':smodels})  

#-------------------------------------------

def update(request, id):  

    smodels = Smodel.objects.get(id=id)  

    form = SmodelForm(request.POST, instance = smodels)  

    if form.is_valid():  

        form.save()  

        return redirect("/show")  

    return render(request,'saeed/edit.html',{'smodels':smodels})  

#---------------------------------------------

def destroy(request, id):  

    smodels = Smodel.objects.get(id=id)  

    smodels.delete()  

    return redirect("/show")  

and here cames the complete app:

can you please inform me where is wrong?
