angularjs - Accessing child scope -


I'm using ngTagsInput angular. My problem comes from trying to gain access to displayTags from an original root scope . It's not there. I want to get access to this because the user can add new tags to display the toggle which is working perfectly. I want to take those new tags and post them. How can I get access to displayTags in $ $ out of the loop?

This type of angular code: 

  var app = angular.module ('recgroups', ['ngTagsInput']); App.directive ('group', function () {return {restrict: 'e', ​​scope: true, templateUrl: '../../Content/templates/RecruitingGroups/Group.html', link: function (scope, El) {// Remove group scope .removeGroup = function (group array, index) {groupArray.splice (index, 1);}}}}); App.directive ('rule' function () {return {restricted: 'e', ​​scope: true, templateUrl: '../../Content/templates/RecruitingGroups/Rule.html', link: function (scope, L) {scope.removeRule = function (ruleArray, index) {ruleArray.splice (index, 1);} scope.addTag = function () {scope $ parent.rule.Rules.push ({});}}}} }); App.directive ('tag', function () {return {restricted: 'e', ​​scope: true, templateUrl: '../../Content/templates/RecruitingGroups/Tag.html', controller: 'displayTags' , Link: function (scope, l) {scope.removeTag = function (tag array, index) {tagArray.splice (index, 1)}}}}}); App.controller ('displayTags', Function ($ Range, Data) {$ scope.displayTags = []; // to manipulate tags as appropriate tag models ($ scope.tag.TagIds! = Null) {$ Each ($ scope.tag.TagIds, function (scopeIndex, scopeValue) {$ .Every (data.Project.Tags, function (tagIndex, tagValue) {if (tagValue.Id == scopeValue) {$ scope.displayTags.push ({Id: tag value id, name: tag value .name, project id: tag value.projectId}}}}}}});}});   I am also submitting this image as a visual display of HTML: </ code> </ pre> <p> Image details Simplifying HTML is so much: </ p> <pre> <code> group ng-repeat =  gt; & lt; rules ng-repeat = "Rules in the Group Rule Rule." & Gt; & gt; Tag ng-Repeat = "Tag Rule in Rules">  input-ng-model = "displayTags" display-property = "name "& Gt; & lt; / tag Input & gt; & lt; / tag & gt; & lt; / rules & gt; & lt; / group & gt;    
 
  scope: true , you can use   scope: {displayTags : '=' // Bi-D (If parent =  ^ model } is  , You can use  
  app.directive ('tag', function ()) {{return restricted: 'e', ​​scope: true, requires: "ngModel ", TemplateUrl: '../../Content/templates/RecruitingGroups/Tag.html', link: function (scope, L, attrs, ngModelCtrl) {Scope.doSomething = function () {ngModelCtrl. $ SetViewValue ('test'); // update model}}}});

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...
