Relax session ember-cli addon

Install

$ ember install @ampatspell/ember-cli-relax-session

Configure Session

Optionally extend Session service:

// app/services/session.js
import Ember from 'ember';
import Session from 'relax-session/services/session';

export default Session.extend({

  onRestored: function() {
  },

  onSaved: function() {
  },

});

Extend Session model:

// app/models/session.js
import Session from "relax-session/models/session";

export default Session.extend({

  authenticated: DS.attr('boolean'),
  roles: DS.attr('raw'),
  author: DS.belongsTo('author', {async: true}),

  // load additional relationships after login if necessary
  loadRelationships: function() {
    return this.get('author.promise');
  },

});

Restore session in application route:

// app/routes/application.js
import Ember from 'ember';

export default Route.extend({

  session: Ember.inject.service(),
  
  beforeModel: function() {
    this._super(...arguments);
    return this.get('session').restoreOnce();
  }

});

Configure Requirements

Extend Requirements service:

// app/services/requirements.js
import Requirements from 'relax-session/services/requirements';
import requirements from '../requirements';

export default Requirements.extend({

  requirements: requirements,

});

Add requirements

import Ember from 'ember';

export default {
  'anonymous': function() {
    if(!this.get('authenticated')) {
      return;
    }
    return 'logged-in';
  },
  'logged-in': function() {
    if(this.get('authenticated')) {
      return;
    }
    return 'login';
  },
  'moderator-or-author': function(model) {
    Ember.assert("model is required", Ember.typeOf(model) === 'instance');
    if(!this.get('authenticated')) {
      return 'login';
    }
    if(this.get('author.content') === model) {
      return "is-author";
    }
    if(this.get('roles').indexOf('moderator') !== -1) {
      return "is-moderator";
    }
    return 'denied';
  }
};

Add RequirementRouteMixin:

// app/routes/base.js
import Ember from 'ember';
import RequirementRouteMixin from 'relax-session/mixins/requirement-route';

export default Ember.Route.extend(RequirementRouteMixin, {

  // before model requirement
  require: 'logged-in',

  // requirement response to route name mapping
  requireMapping: {
    'login':       'sessions.new',
    'denied':      'sessions.denied',
    'logged-in':   'index',
    'is-author':    null,
    'is-moderator': null,
  },

});

Optionally add after model requirements:

// app/some-route.js
import Route from './base';

export default Route.extend({
  model: function(params) {
    return this.store.find('thing', params.id);
  },
  afterModel: function(thing) {
    var author = thing.get('author');
    return this.validateRequirement('moderator-or-author', author);
  },
});
