On my homepage, I have both a log_in and sign_up form. Initially, the log_in form is displayed by default, but when a user clicks on the Sign Up button, the sign_up form appears. These toggles switch depending on which button the user clicks.
from django import forms
class LogInForm(forms.Form):
pass
class SignUpForm(forms.Form):
pass
Both forms call the same view - index_view().
If you're having trouble figuring out which form is being submitted in Django, it's probably because the necessary information is missing in the POST request. The most effective way to resolve this issue is by specifying that information in the submit button, just like you would with any other form element.
<form action="." method="POST">
{{ login_form.as_p }}
<input type="submit" name="login" value="login">
</form>
<form action="." method="POST">
{{ signup_form.as_p }}
<input type="submit" name="signup" value="signup">
</form>
In your view, you can then easily determine which form was submitted by checking the content of the POST data:
if 'login' in request.POST:
# Process login_form
else:
# Process signup_form
To implement another approach, you can include a GET parameter in the URL and then check it within the view:
<form action="{% url index %}?action=login">
Within the corresponding view function:
def index_view(request):
action = request.GET.get('action', '')
if action == 'login':
