java - Custom Hibernate insert for collections, counterpart of @WhereJoinTable -


I'm trying to map a relationship with an additional feature (flag) in an additional table, but without I am clearly defining this host table in one unit.

Problem:

Trade has been assigned to 0 or 1 main country, trade is also linked to 0 or more secondary countries.

I have three tables: business , country , business_Country

my business In , I have @WhereJoinTable which works well to get back: 

  @OneToOne @JoinTable (name = "business_country", joinColumns = @JoinColumn (name = "business_id"), inverseJoinColumns = @JoinColumn (name = "country_id") @ @jinJinTable (volume = "is_main = 1") private country's main country; @OneToMany @JoinTable (name = "business_country", joinColumns = @JoinColumn (name = "business_id"), inverseJoinColumns = @JoinColumn (name = "country_id")) @WhereJoinTable (section = "is_main = 0") set & Lt; Country & gt; Secondary countries = new hashets & lt; & Gt; ();   
 I wonder what would be the equivalent  @WhereJoinTable  to save.  
 Simply create a unit  business  and adding a country to do this gives an infringement violation: ("TESTSCHEMA" "BUSINESS_COUNTRY" "IS_MAIN")  
   
 What I have to do, is that is_main  1  for  main country  and  is set to  for all entries in secondary countries .  
 I was wondering if any custom  @SQLInsert ?   
 
 You can use the union table to specify a custom SQL insert statement:  
  @OneToOne @JoinTable (name = "business_country", joinColumns = JoinColumn (name = "business_id"), inverseJoinColumns = @JoinColumn (name = "country_id")) @WhereJoinTable (section = "is_main = 1 ") @SQLInsert (SQL =" enter business_country (business_id, country_id, Is_main) value (?,?, 1) ") Country of private country; @OneToMany @JoinTable (name = "business_country", joinColumns = @JoinColumn (name = "business_id"), inverseJoinColumns = @JoinColumn (name = "country_id")) @WhereJoinTable (volume = "is_main = 0") @SQLInsert (SQL = "Business_country (business_id, country_id, is_main) enter value (? in?, 0)") Private set & lt; Country & gt; Secondary countries = new hashets & lt; & Gt; ();   
 And the articles can also be useful (note the order of the columns in inserting statements).

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...
