No input for email in my tempate - django

Question

I have a form where I must enter e-mail, but in the template do not have space for input, only after passing the validation window appears with the introduction e-mail.
At this moment I see only send button.
This is my code:
<div class="col-lg-6">
<form action="./" method="post">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="send">
</form>
</div>
model.py
class InputEmail(models.Model):
email = models.EmailField()
def __unicode__(self):
return self.email
forms.py
from models import InputEmail
from django import forms
class EmailForm(forms.ModelForm):
class Meta:
model = InputEmail
fields = ('email',)
views.py
class Home(View):
template_name = 'index.html'
def get(self, request):
return render(request, self.template_name)
def post(self, request):
if request.method == 'POST':
form = EmailForm(request.POST)
if form.is_valid():
form.save()
messages.success(request, "You send e-mail to us!")
return HttpResponseRedirect('./')
else:
form = EmailForm()
return render(request, 'index.html', {
'form': form
})
The rest - writing and reading from the database works fine.
How enter the input and give it a style?

Answer 1

well the problem is that the first time you arrive to the view the get method is being called (and it is okay, since this is a GET request).
But, inside that get method you are not sending your form to the template. So it can't be rendered.
instead, your get method should look like that:
def get(self, request):
form = EmailForm()
return render(request, self.template_name, {"form": form})
note that the condition in the post method is redundant. You have an "else" but you never get there since the post method is only called when it is a POST request.
Meaning your post method should look like this:
def post(self, request):
form = EmailForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('./')
return render(request, self.template_name, {
'form': form
})
