I have a Django view that signs a user up to a free trial through Stripe. When the view makes a POST request, it does so twice.
I've tried idempotency keys, both after the if request.method == 'POST' line and in the initial rendering of the view. The customer in Stripe always ends up with two identical payment sources and two identical subscriptions to the plan.
def start_trial(request):
title = 'get started'
description = title
form = MembershipForm()
key = settings.STRIPE_PUBLISHABLE_KEY
trial_days = 30
coupon = None
custom_message = ''
subscription_idempotency = str(uuid.uuid4())
source_idempotency = str(uuid.uuid4())
try:
vendor = Vendor.objects.get(user=request.user)
custom_message = vendor.message
coupon = Coupon.objects.get(vendor.coupon)
coupon = coupon.stripe_coupon_id
trial_days = vendor.trial_days
except Vendor.DoesNotExist:
pass
try:
partner = Partner.objects.get(user=request.user)
custom_message = partner.message
coupon = Coupon.objects.get(partner.coupon)
coupon = coupon.stripe_coupon_id
trial_days = partner.trial_days
except Partner.DoesNotExist:
pass
if request.method == 'POST':
form = MembershipForm(request.POST)
if form.is_valid():
user = request.user
plan = Membership.objects.get(type_of=form.cleaned_data['plan'])
# stripe needs to attempt to create a customer
# TODO what if there's already a membership/subscription?
user_membership = UserMembership.objects.get(user=request.user)
stripe_subscription = stripe.Subscription.create(
customer=user_membership.stripe_customer_id,
items=[
{"plan": plan.stripe_plan_id}
],
trial_period_days=trial_days,
coupon=coupon,
idempotency_key=subscription_idempotency,
)
subscription = Subscription.objects.create(
user_membership=user_membership, stripe_subscription_id=stripe_subscription.id)
subscription.save()
stripe.Customer.create_source(user_membership.stripe_customer_id,
source=request.POST.get('stripeToken'),
idempotency_key=source_idempotency)
user_membership.membership = plan
user_membership.save()
user.is_subscriber = True
user.save()
# if subscription status is incomplete, display error.
# if passes, redirect to onboarding
message = 'yay'
messages.success(request, message=message)
return HttpResponseRedirect('/onboarding/')
return render(request, 'memberships/free_trial.html',
{'title': title, 'description': description, 'form': form,
'key': key, 'custom_message': custom_message})
Data always ends up in Stripe twice. Log shows:
[18/Jun/2019 11:05:21] "POST /memberships/free-trial/ HTTP/1.1" 302 0
[18/Jun/2019 11:05:22] "POST /memberships/free-trial/ HTTP/1.1" 302 0
Thanks to #duck for pointing me in the right direction. I had unseen (to me) JavaScript duplicating what was happening in the view. Removed the offending file and the problem is solved.

any help to archive an option of adding a free listing option while using stripe?`
I guess you want to offer a free trial for you customer? If so, you can specify a trial_end or trial_period_days when creating a subscription. Alternatively, you can also use a coupon to apply discounts to invoices generated for this particular subscription.
Here is the users account view that i want users to be able to like their post from, it has really been a challenge to get my head around this. would appreciate some help.

Here is my like view, how best do can i accomplish users and friends being able to like their post from their own profile or timeline ?

Like.objects.create(user=user, post=post)
resp = {
'liked':liked
}
response = json.dumps(resp)
return HttpResponse(response, content_type = "application/json")
The error occurs either because likeId is sent as an empty string http://url_path?likeId=, or (most probably) because it is not present in the request.GET at all.
You've used request.GET.get("likeId", "") so the default value is "".
Next, the code runs post_id = Post.objects.get(pk=post_id). It's forbidden to pass a string to a pk filter, hence the error. So, verify the likeId is indeed send in the request and it's an actual Post.id (check for possible typos). Maybe you've meant to use request.POST instead?
Generally, it's a bad idea to use dict.get() where you clearly DO need an value. Also, there should be some validation in place to ensure the likeId is a valid integer. I would recommend validating input parameters with a form, but a manual approach is also possible.
try:
post_id = int(request.GET["likeId")
except (KeyError, ValueError):
return HttpResponse('Provide a valid likeId integer', status_code=404)
In my view function, I'm trying to make 2 modifications to the current user; consider him a premium subscriber by marking model field is_premium_subscriber as True and adding him to a group named Premium Agents.
However the changes don't seem to be registering in my views.py! Here is my code:

premium_agent_group = Group.objects.get(name='Premium Agents')
premium_agent_group.user_set.add(request.user) # This is not working either, the current user does not get added to the group.

The template is fine.
Now watch forms.py when i do list_visit_ids = ModelChoiceField(queryset=Visit.objects.all(), empty_label='Select Revisit ID',required=False) It works perfectly fine on my local machine.But on my server it has around 6000 visit objects so this page hangs or i should say keep on loading.
So initially i changed it to list_visit_ids = ModelChoiceField(queryset=Visit.objects.none(), empty_label='Select Revisit ID',required=False)
Now i know that by this the form becomes invalid and should go to the else part Now my question how do i make reference_visit=cd['list_visit_ids'] in else (form is invalid)
case save().How do i override the none() attribute.
Thanks in advance i will really appreciate.
If your goal is to save your html page load by removing the 6000 choices (which I've done too: 10000+ <option> fields wrapped by misc html will absolutely choke a page), you shouldn't be using a ChoiceField at all. By setting queryset=Visit.objects.none() you're allowing zero choices and nothing passed in will validate.
You either show 6000 select item drop downs, radio boxes, etc., or find a way to /not/ have a giant select drop down (such as a hidden input or charfield), not fake around a ModelChoiceField who's main purpose is to populate that select drop down and validate.
In short: don't use a ModelChoiceField if you're not going to be using the html choices generated by it. Use something else and do the validation / model pulling yourself via the clean_FOO methods.

my_input = forms.CharField()

Why don't you use https://github.com/django-mongodb-engine/mongodb-engine it works almost perfect with Django ORM. Works like a charm for me.
