Try this...
def send_email(request,id):
customer=get_object_or_404(Customer,pk=id)
form=Customer_Email_Form()
customers=Customer.objects.all()
context={"customer":customer,"email_form":form,"customers":customers}
if request.method == 'GET':
return render(request,'crm/listing.htm.html',context)
if request.method=='POST':
form=Customer_Email_Form(request.POST)
if form.is_valid():
form.save()
messages.success(request,"Email Sent")
return render(request,'crm/listing.html',context)
return render(request,'crm/listing.html',context)
You were passing POST data to your form before any was sent, and then rendering the form. I find it easier/clearer to restructure as such:
def send_email(request,id):
if request.method=='POST':
form=Customer_Email_Form(request.POST)
if form.is_valid():
form.save()
messages.success(request,"Email Sent")
return redirect('send_email', id)
else:
messages.error(request, form.errors)
return redirect('send_email', id)
else:
customer=get_object_or_404(Customer,pk=id)
form=Customer_Email_Form()
customers=Customer.objects.all()
context={"customer":customer,"email_form":form,"customers":customers}
return render(request,'crm/listing.html',context)
Assuming that you have imported redirect and your url name in urls.py is 'send_email'.
