Populate new courses so that they can be previewed

[canstudios-nicolaw]

Fixes #1678

When you create a course the new course contains a page, article, block and text component. This means that the course can be previewed immediately.

I've put some text in the text component for now which I don't think will be final. We discussed some sort of welcome text in the stand up but didn't specify what it would be. Do we want just a straightforward 'This is an adapt course' type message or something a little more detailed that explains ABC?

I don't think this file will be necessary after the refactor PR

Block layoutOptions are not populated. Not sure if that matters? Otherwise looks good.

[canstudios-nicolaw]

I wondered about that to. It didn't seem to do any harm when I took them out, so I left them out. Am happy to put them back in if that's the standard thing though

[canstudios-nicolaw]

I have added the block layout options to be on the safe side.

(I'm off next week so I don't want things waiting on me)

It would ne nice if we can make this localizable ... or maybe use "Lorem ipsum ..." instead.

[taylortom]

+1, think that's a good idea @lc-thomasberger

[taylortom]

Just noticed that various colorPicker assets have changed permissions, was this intentional?

[canstudios-louisem]

No im not sure how that even happened must have been during the rebase.

[taylortom]

All works well :)

Could we maybe remove the nesting in the main function for readability? Something like:

populateNewCourse: function(model, response, options) {
  this.createGenericPage(model);
},

createGenericPage: function(courseModel) {
  var contentObjectModel = new ContentObjectModel({
    title: Origin.l10n.t('app.placeholdernewpage'),
    displayTitle: Origin.l10n.t('app.placeholdernewpage'),
    _type: 'page',
    _courseId: courseModel.get('_id'),
    _parentId: courseModel.get('_id')
  });
  contentObjectModel.save(null, {
    error: _.bind(this.onSaveError, this),
    success: _.bind(this.createGenericArticle, this)
  });
},

createGenericArticle: function(pageModel) {
  var articleModel = new ArticleModel({
    _courseId: pageModel.get('_courseId'),
    _parentId: pageModel.get('_id'),
    _type: 'article'
  });
  articleModel.save(null, {
    error: _.bind(this.onSaveError, this),
    success: _.bind(this.createGenericBlock, this)
  });
},

createGenericBlock: function(articleModel) {
  var blockModel = new BlockModel({
    _courseId: articleModel.get('_courseId'),
    _parentId: articleModel.get('_id'),
    _type: 'block',
    layoutOptions: [
      { type: 'left', name: 'app.layoutleft', pasteZoneRenderOrder: 2 },
      { type: 'full', name: 'app.layoutfull', pasteZoneRenderOrder: 1 },
      { type: 'right', name: 'app.layoutright', pasteZoneRenderOrder: 3 }
    ]
  });
  blockModel.save(null, {
    error: _.bind(this.onSaveError, this),
    success: _.bind(this.createGenericComponent, this)
  });
},

createGenericComponent: function(blockModel) {
  // Store the component types
  var componentTypes = new EditorCollection(null, {
    model: ComponentTypeModel,
    url: '/api/componenttype',
    _type: 'componentTypes'
  });
  componentTypes.fetch({
    error: _.bind(this.onSaveError, this),
    success: _.bind(function() {
      var componentModel = new ComponentModel({
        _courseId: blockModel.get('_courseId'),
        _parentId: blockModel.get('_id'),
        body: Origin.l10n.t('app.projectcontentbody'),
        _type: 'component',
        _component: 'text',
        _componentType: componentTypes.findWhere({ component: 'text' }).attributes._id,
        _layout: 'full'
      });
      componentModel.save(null, {
        error: _.bind(this.onSaveError, this),
        success: function() {
          Origin.router.navigateTo('/editor/' + componentModel.get('_courseId') + '/menu');
        }
      });
    }, this)
  });
}

I have made changes on the pr since i reviewed it initially

[canstudios-nicolaw]

@taylortom I've refactored as per your suggestion (thanks for the code!). We have removed those colourPicker asset changes - sorry we didn't notice those as they didn't show on bitbucket.

[lc-thomasberger]

Localizable Strings would be nice.
