javascript - Headers in post request with Backbone.js -


I want to insert a header in my post service with a backbone.js in a post request, I try in two ways I do: 

  this.model.save ({header: {'x-token': myToken}});   
 Var name = "xtoken" + "="; Var ca = document.cookie.split (';'); (Var i = 0; i & lt; ca.length; i ++) for {var c = ca [i] .trim (); If (c.indexOf (name) == 0) tokenCookie = c.sublstring (name.length, c.length); } Xhr.setRequestHeader ('X-token', tokencookie); }   
 call:  
  this.model.save ({before.Send: this.sendToken, success: work () {alert ("success" );}, Error: function (model, response, option) {warning ("error");}});   
 But this does not seem to work, it does not send the header   
 
 
 The sign is for the  model. Save ([attributes], [options]) . To add an option, you must give an empty / zero hash of properties:  
  this.model.save (null, {headers: {'X-Token': 'myToken'}});   
 and a demo  
 or  
  this.model.save (null, {beforeSend: function (xhr) {xhr. SetRequestHeader ('x-token', 'set token');}});

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...
