ruby on rails - Error message in partial rendered twice -


I was practicing with the ROR tutorial, and there is a strange problem where error message was provided twice.

new.html.slim 

  - Provide (title, 'sign up') h1 sign div class = " Row "div class =" col-sm-6 col-sm-offset-3 "= form_for (@ user, html: {role:" form "}) do | F | = 'Shared / error_message' div class = "form-group" = f.label: name = f.text_field: name, class: "form-control" div class = "form-group" = f.label: email = F.text_field: email, class: "form-control" div class = "form-group" = f.label: password = f.password_field: password, category: "form-control" div class = "form-group" = F.label: password_confirmation, "confirmation" = f.password_field: password_confirmation, category: "form-control" = f.submit "create account", category: "btn btn-LG btn-primary"   
 In this code (line 7) I am providing a partial  shared / error_ message  The I page is being called in this way:  
  User S_controller.rb   
  def create user @user.net (user_update) if user @   
 any ideas?       
> 
 Edit: Added partial  
  = If @ User.errors.any? Div # error_explanation div class = "alert alert-danger" | Form = "#{@user.errors.count}". Error (s) ul - @user.ros.ful__ messages.each do | Msg | | Li = "# {msg}"    
 
 
 I think you have a syntax error  
 = If @ user.errors.any?  
 Partial to  
 - If @ user.errors.any?

Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

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...
