django - Modify image extension to use later -


I am using the PIL in the document to crop the image and save the copy of it: 

  Image.save (os.path.abspath (os.path.join (os.path.dirname (__ file __), '..')) + kid.image_url + "thumbnail", "JPEG")   
 The image thumbnails are temporarily saved and can be accessed at:  
  kid.image_url + "Thumbnail"   
 I have a problem save it in the original format, do not have a thumbnail and access it later Be enabled. Is there a better solution, such as "_ thumbnail" after the image and it should be able to access it by the child .image_url + "_ thumbnail"   
 
 
 Here you can change "example.jpg" to "example.thumb.jpg": < / P> 
  Import OS filename, extn = os.path.splitext (kid.image_url) thumb_filename = filename + ". Thumb" + extn

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
