How to make directive use the controller specified in directive attribute?


So I have a directive:

<directive data="user" templateUrl="./user.html" controller="UserController"></directive>

I want that directive to use the controller specified in "controller" attribute, as you see above.

Is it possible with AngularJS directives? Or should I do it other way, maybe with components?

My code currently looks like this:

app.directive('directive', function() {
        
        var controllerName = "UserController"; // i want that to dynamicaly come from attribute
        
        // check if controller extists:
        var services = [];
        app['_invokeQueue'].forEach(function(value){ 
            services[value[2][0]] = true;
        });         
        if (!services[controllerName]) controllerName = false;
        
        return {
            
            scope: { 'data' : '=' },

            link: function (scope) {
                
                Object.assign(scope, scope.data);
            },
            
            templateUrl: function(element, attr) {
                
                return attr.templateurl;
            },
            
            controller: controllerName
            
        }
        
    });

Solution

  • Okay, so after analysing Petr's answer I post the working code using nested divs:

    app.directive('directive', function() {
            
            return {
                scope: { 'data' : '=' },
                
                link: function (scope) {
                    
                    // this makes your fields available as {{name}} instead of {{user.name}}:
                    Object.assign(scope, scope.data);
                    
                },
                
                template: function(element, attrs) {
                    
                    var controllerName = attrs.controller;
                    var controllerString = controllerName + ' as vm';
                    
                    // check if controller extists:
                    var services = [];
                    app['_invokeQueue'].forEach(function(value){ 
                        services[value[2][0]] = true;
                    })
                    
                    if (!services[controllerName]) {
                        
                        return '<div ng-include="\'' + attrs.templateurl + '\'"></div>'; 
                        
                    } else {
                        
                        return '<div ng-controller="' + controllerString + '"><div ng-include="\'' + attrs.templateurl + '\'"></div></div>';
                            
                    }
                }
            }
            
        });
