Question

i am working on django application where admin can set pricing,and give coupon, my proble is how to offer a free option or free listing whe you are using stripe.
this is a function on my views.py
`#login_required(login_url='/users/login')
def create_ad_func(request):
user = request.user
if request.method == "POST":
data = dict(request.POST)
data = clean(data)
ad = AdList.objects.create_ad(**data)
img_counter = 0
img_files = request.FILES
if len(request.FILES) > 0:
for ad_img in request.FILES:
print(img_files[ad_img])
upload_img(ad_img, img_files, ad)
else:
url = upload_image(request.FILES[ad_img], ad.id, img_counter)
img_counter = img_counter + 1
data[ad_img] = url
date_time = arrow.utcnow().format('YYYY-MM-DD HH:mm:ss')
data['post_date'] = date_time
pprint(data)
AdList.objects.filter(pk=ad.id).update(**data)
objectss = AdList.objects.filter(pk=ad.id)
subscription_list = ['urgent_ad', 'regular_ad', 'featured_ad']
for key in data.keys():
if key in subscription_list:
ad_subscription = AdSubscription.objects.values()[0]
price = ad_subscription[key]
charge = ad_subscription[key] * 100
print(price, charge)
key = settings.STRIPE_PUBLISHABLE_KEY
return render(request, 'checkout.html', {"user": request.user, 'ad': ad, 'price':price, 'key':key, 'charge':charge})
else:
ad_subscription = AdSubscription.objects.values()[0]
return render(request, 'ad-list-cat.html', {"user": request.user, "subscription": ad_subscription})
and this is my manage.py
class AdListManager(BaseUserManager):
"""
Custom user model manager where email is the unique identifiers
for authentication instead of usernames.
"""
def create_ad(self, **data):
"""
Create and save a User with the given email and password.
"""
email = data["email"]
email = self.normalize_email(email)
ad = self.model(**data)
ad.save()
message="your ad was published successiful"
return ad,message
def update_ad(self, pk, data):
pprint(data)
self.model.objects.filter(pk=pk).update(**data)
def list_ads(self, email):
return self.model.objects.filter(email=email)
i tried to modify so that if the value is les than <5 charge 0 but problem is that stripe do not accepte zero charge.
this is what i tried.
#login_required(login_url='/users/login')
def create_ad_func(request):
user = request.user
if request.method == "POST":
data = dict(request.POST)
data = clean(data)
ad = AdList.objects.create_ad(**data)
img_counter = 0
img_files = request.FILES
if len(request.FILES) > 0:
for ad_img in request.FILES:
print(img_files[ad_img])
upload_img(ad_img, img_files, ad)
else:
url = upload_image(request.FILES[ad_img], ad.id, img_counter)
img_counter = img_counter + 1
data[ad_img] = url
date_time = arrow.utcnow().format('YYYY-MM-DD HH:mm:ss')
data['post_date'] = date_time
pprint(data)
AdList.objects.filter(pk=ad.id).update(**data)
objectss = AdList.objects.filter(pk=ad.id)
subscription_list = ['urgent_ad', 'regular_ad', 'featured_ad']
for key in data.keys():
if key in subscription_list:
ad_subscription = AdSubscription.objects.values()[0]
if ad_subscription[key] < 5:
# save the subscription without charging with stripe
ad.subscriptions.create(
items=[{
'price': 'price_id',
'quantity': 1,
}],
expand=['latest_invoice.payment_intent']
)
price = 0
charge = 0
else:
price = ad_subscription[key]
charge = ad_subscription[key] * 100
key = settings.STRIPE_PUBLISHABLE_KEY
return render(request, 'checkout.html', {"user": request.user, 'ad': ad, 'price':price, 'key':key, 'charge':charge})
else:
ad_subscription = AdSubscription.objects.values()[0]
return render(request, 'ad-list-cat.html', {"user": request.user, "subscription": ad_subscription})
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.
