Specific questions related to Django forms.
Quote from the official documentation:
Handling forms is a complex business. Consider Django’s admin, where numerous items of data of several different types may need to be prepared for display in a form, rendered as HTML, edited using a convenient interface, returned to the server, validated and cleaned up, and then saved or passed on for further processing.
Django’s form functionality can simplify and automate vast portions of this work, and can also do it more securely than most programmers would be able to do in code they wrote themselves.
Django handles three distinct parts of the work involved in forms:
preparing and restructuring data to make it ready for rendering creating HTML forms for the data receiving and processing submitted forms and data from the client It is possible to write code that does all of this manually, but Django can take care of it all for you.
An example form from the documentation:
from django import forms
class ContactForm(forms.Form):
subject = forms.CharField(max_length=100)
message = forms.CharField()
sender = forms.EmailField()
cc_myself = forms.BooleanField(required=False)
An example of how to validate a form with (validated) POST data:
from django.core.mail import send_mail
if form.is_valid():
subject = form.cleaned_data['subject']
message = form.cleaned_data['message']
sender = form.cleaned_data['sender']
cc_myself = form.cleaned_data['cc_myself']
recipients = ['info@example.com']
if cc_myself:
recipients.append(sender)
send_mail(subject, message, sender, recipients)
return HttpResponseRedirect('/thanks/')
An example of how a form could be rendered in a template:
<form action="/your-name/" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Submit">
</form>
