tinysql Key Features

Gives a simple interpretation of SQL and relational algebra in preparation for the following course.

Explains the life of a read-only SQL, which includes parsing, execution, and the optimization of SQL plans.

Focuses on SQLs (including DML and DDL) that change the state of the database: how they get implemented and how to deal with the interaction of them and read-only statements.

QUESTION

Angularjs update variable on ng-change

Asked 2017-Apr-25 at 19:36

I have two groups of checkboxes where values are set to a variable to save it to the database as a string.

How can I "update" this variable if I come back to checkboxes page and check/uncheck them?

I tried with ng-change but the firsts checked values repeat on every check click or all the values are removed on uncheck click and I get NaN on console.log

<form class="list">

    <ion-toggle toggle-class="toggle-balanced" ng-model="data.turnOnOff" ng-true-value="'On'" ng-false-value="'Off'" ng-change="data.openDatabases(data.turnOnOff)">Databases</ion-toggle>
    <div class="spacer" style="height: 10px;"></div>

    <ion-list ng-show="bd">
        <ion-checkbox ng-repeat="(key, value) in db" ng-model=value.checked ng-change="data.checkChanges()">{{ value.text }}</ion-checkbox>
    </ion-list>
    <div class="spacer" style="height: 10px;"></div>


    <ion-toggle toggle-class="toggle-balanced" ng-model="data.escritorio" ng-true-value="'On'" ng-false-value="'Off'" ng-change="data.openEscritorio(data.escritorio)">Office</ion-toggle>
    <div class="spacer" style="height: 10px;"></div>

    <ion-list ng-show="officee">
        <ion-checkbox ng-repeat="(key, value) in office" ng-model=value.checked ng-change="data.checkChanges()">{{ value.text }}</ion-checkbox>
    </ion-list>
</form>

Using the ng-change directive on your input will allow you run some operations on your $scope.db object.

Basically, when a change from true to false occurs (or the other way around), the function will run and determine if the new value is true. If it is, it gets push'd into a new array called $scope.filteredDatabases.

If the new value is false, it is removed from $scope.filteredDatabases.

The last bit is simply running a join operation on the $scope.filteredDatabases array, in this case, joining with a comma.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope, $filter) {


 $scope.db = [
    {text:'Firebird', checked:'false'}, 
    {text:'MongoDB', checked:'false'}, 
    {text:'mSQL', checked:'false'}, 
    {text:'MySQL', checked:'false'}, 
    {text:'Oracle', checked:'false'}, 
    {text:'PostgreSQL', checked:'false'}, 
    {text:'TinySQL', checked:'false'}, 
    {text:'SQLite', checked:'false'}, 
    {text:'SQL Server', checked:'false'}, 
    {text:'Sybase', checked:'false'}, 
    {text:'Outros', checked:'false'}
 ];


  $scope.filteredDatabases = [];

  $scope.notifyChange = function(item) {
    if (!!item.checked){
       $scope.filteredDatabases.push(item.text);
    }
    else {
      var index = $scope.filteredDatabases.indexOf(item);
      $scope.filteredDatabases.splice(index, 1);
    }
    
     $scope.filteredString = $scope.filteredDatabases.join(',');
  };
