groovy - Launch grails command from grails application -


I'm trying to run a Grails command like "grails help" from Grails App but I ended up all the efforts "Error: The main org.codehaus.groovy.grails.cli.support.GrailsStarter" can not be found or can not be loaded.

Actually, I have tried 

  def p1 = "grails help" .execute () p1.waitFor () println "return code: $ {p1.exitValue ()} "Println" stderr: $ {p1.err.text} "println" stdout: $ {p1.in .text} "  
 Also:  
  Runtime Runtime = Runtime.Tat Timetime () Process = Runtime. XAC ("grails help") process.waitFor () Println "return code: $ {process.exitValue ()}" println "stderr: $ {process.err.text}" println "stdout: $ {process.in.text} }   
 and finally:  
  def sout = new stringbuffer () def serr = new stringbuffer () last processbilder = new processbilder () processBuilder. Process (new file ("/ myFolder")) Processbuilder.command (["grails", "help"]) println processBuilder.dir Ectory () process proc = processbuilder.start () proc.consumeProcessOutput (south, serr) def status The command "grails help" is not the one I want to execute, Ekin will be necessary for me to run to fix it right up.  
   
 
 
 If I create a new app with grails 2.3. 5 ( grails create-app script-test ), then change one controller ( create grails- test the controller, run ) and change it so that it looks:  
  Package Test Class Run Controller {DEF Index () {DFTT = ['Grays', 'Help']. Execute (). Text "and lethinum; pre & gt; ttdtat / pre & g;" }}   
 Then run it from  grails run-app , and go to  localhost: 8080 / script-test / run  Grails Get help on the screen provided in the form of a web page text  
 The problem you have is that it will not work in production because you probably have a  war  file, so you will not know where you are, or you (If it is actually installed on the server)  
 I think that you need to think again your strategy, whatever you are doing, you are trying to do the following: - (

c - Mpirun hangs when mpi send and recieve is put in a loop -

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...
