javascript - Determine image dimensions for image stored in GridFS from meteor -


I'm trying to determine the width of an image stored in the grid on summer so that I can resize a modal dialog Can do

I have a helper for the template 

  Template.projectImageModalInner.image = function () {var imageId = Session.get ("selectedImageId"); //console.log ("Plug-in Image Model Inner Image:" + imageId); Var image = imageFS.findOne ({_ id: imageId}); Url = image.fileHandler.default1.url; Console.log (url); Console.log (Imagemagick.identify (url)); Return imageFS.findOne ({_ id: imageId}); }   
 displaying the correct image to display, but I'm really having trouble getting the shape. Call Imagemagick. The identity can not be identified on an undefined method to "blow up" with an error, even though the above line print the correct URL.  
 Console log for image URL shows  
  /cfs/images/i5mSRED6mYgo2vK84_default1.jpg   
 The correct image displayed in the template URL is  
 I want to set a session, eventually make changes in the width of the image so that the dialog is dynamically shaped.  
 I have tried to get this size from HTML (no joy) from other assistants, but nothing is working till now.  
 Can anyone say what I am doing wrong here, or can I suggest another way? I think that you will have to use the GraphicSocial / ImageMagic Library on the server-side after uploading to get the image size.  
 First, code> gm.size () , then attach those values ​​to those

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.
