How do I generate and parse JSON in Ruby? -


I need to create and parse a JSON in Ruby.

In my case, JSON should have a string value in the form of a key, and an array of strings should be in the form of its value.

Something like this ... 

  JSON: key1 - & gt; {A, b, c} key2 - & gt; {D, e, f}   
 My question: 1.) How can we do this? Is there a JSON parsing library in Ruby or do I have to apply it myself?  
 2.) I'm coming from Java domain. In Java, we have a map, hash map, hamp, lidapap etc. Do we have the same facility in Ruby?   
 
 
 The JSON you are describing when you create it, will look like this:  <">" key1 ": [" a1 ": [" a "," b "," c "]," key2 "You can call it in Ruby using JSON Library and by calling  #to_json  On a ruby ​​hash:  
  requires 'json': ["d", "e", "f"]}   
 Data_hash = {key1: ['a', 'b', 'c'], key 2: ['d', 'e', ​​'f']} json_data_string = data_hash.to_json   
 You can parse it using the same JSON library:  
  required 'json' json :: parse (json_data_string)   
 Take a look at this.

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. 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...
