I am learning Django and am trying to create a form that I can submit a participant's information to the database.
I have an index view, which list all the participants:
http://127.0.0.1:8000/participants/
Clicking a button on the index will go to form submission:
http://127.0.0.1:8000/participants/add_participant/
After submitting the form, the page goes back to the index view, but the URL is not correct, it stucks at http://127.0.0.1:8000/participants/add_participant/
If I refresh the browser immediately, it will add another record to the database.
add_participant.html
<!DOCTYPE html>
<html>
<head>
<title>This is the title</title>
</head>
<body>
<h1>Add a Participant</h1>
<form id="participant_form" method="post" action="/participants/add_participant/">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" name="submit" value="Create Participant" />
</form>
</body>
</html>
views.py
from django.shortcuts import render, get_object_or_404, redirect
from django.http import HttpResponse, HttpResponseRedirect
from participants.models import Participant
from .forms import ParticipantForm
# Create your views here.
def index(request):
participant_list = Participant.objects.order_by('-first_name')[:50]
context = {'participants': participant_list}
return render(request, 'participants/index.html', context)
def add_participant(request):
if request.method == 'POST':
form = ParticipantForm(request.POST)
if form.is_valid():
form.save(commit=True)
return index(request)
else:
form = ParticipantForm()
return render(request, 'participants/add_participant.html', {'form': form})
urls.py
from django.conf.urls import url
from . import views
from .models import Participant
app_name = 'participants'
urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'add_participant/$', views.add_participant, name='add_participant'),
]
I tried switching the
return index(request)
to:
return HttpResponseRedirect("http://127.0.0.1:8000/participants/")
It solves the problem...but I doubt this is the "right" way to do it. What is the correct way to fix this issue?
You can pass just the path to the redirect response:
return HttpResponseRedirect("/participants/")
This way if you change your domain, the redirect will work.
an other solution is to use reverse
from django.core.urlresolvers import reverse
# ...
return HttpResponseRedirect(reverse(index))
