Orchard Alternate Shape Template Not Displaying Values - orchardcms

I'm new to Orchard and have watched both the Pluralsight "Orchard Fundamentals" and "Advanced Orchard" tutorials. Its a great platform, but I'm having a hard time wrapping my head around a couple of things.
I'd like to create a blog showcase banner on the home page only that rotates blog posts on the site. I have the HTML sliced up and functioning on an HTML template. The banner looks like this:
http://arerra.com/news-slideshow.jpg
So far I have done the following:
I've created a Blog called "Articles" and have placed a single post in there for testing.
Added a Layer called "ArticleList" where I have placed a Widget for "Recent Blog Posts"
I've created a custom layout for the home page called "Layout-Url-HomePage.cshtml" in my theme.
In my Theme "Views" folder, I have created a file called "Widget.Wrapper.cshtml" with only #Display(Model.Child) in it to remove the <article><header/><footer /><article> tags globally from the widgets.
Added a file in "Views > Parts > Blogs.RecentBlogPosts.cshtml" to control the layout of my shape. The code is the following:
#using Orchard.ContentManagement;
#{
IEnumerable<object> blogPosts = Model.ContentItems.ContentItems;
}
#if (blogPosts != null) {
<div class="container news-slider">
<ul class="slide-images">
#foreach (dynamic post in blogPosts) {
string title = post.Title;
ContentItem item = post.ContentItem;
<img src="/Themes/MountainWestHoops/Content/img/placeholder-700x380.jpg" alt="#title" class="active" />
}
</ul>
#foreach (dynamic post in blogPosts) {
string title = post.Title;
string body = post.Body;
ContentItem item = post.ContentItem;
<div class="featured-story threeD active">
<h1>#title</h1>
<p>#body #Html.ItemDisplayLink("READ MORE", item)</p>
</div>
}
<aside>
<ul class="tabs">
#foreach (dynamic post in blogPosts) {
string title = post.Title;
string url = post.Url;
ContentItem item = post.ContentItem;
<li><h3>#title</h3></li>
}
</ul>
<div class="ad-three-day-trial">
<img src="/Themes/Content/img/placeholder-260x190.gif" />
</div>
</aside>
</div>
}
My HTML is rendering properly, but none of the values that I have specified are showing up.
I am using the "Shape Tracer" module to see what template is being used. What is funny, is that the #Html.ItemDisplayLink("READ MORE", item) is rendering the article's URL, and if I replace the "READ MORE" with the string title, the title renders properly.
What am I doing wrong here that is causing strings to not display? Am I missing a larger point and misunderstanding the fundamentals? The tutorials seems to say that you can simply move around parts, but in this case, I need to have very specific markup for this slider to work.

Seems like your source was http://weblogs.asp.net/bleroy/archive/2011/03/27/taking-over-list-rendering-in-orchard.aspx
That is a rather old post, and the way the title is handled has changed since then.
The DisplayLink works because the only correct property here is post.ContentItem, which is what that API takes. post.Title and post.Body on the other hand are very likely null, which is why you see nothing. To access the title, you can use post.ContentItem.TitlePart.Title and to get the body, post.ContentItem.BodyPart.Text.

If element hasClass, add another class to its title value

I'm using slick carousel, and once a div is active I want to open the corresponding description.
Problem I'm having is with this code:
if ($('div').hasClass('active')) {
var title = $(this).attr('title');
$('ul li').removeClass('open');
$(title).addClass('open');
}
What I'm trying to achieve:
Once a div gets class 'active', I want to take its title value, and use it as a id link to list element I want to display(add class to).
Here is a FIDDLE.
Use event handling, not class monitoring.
The slick carousel API has events for this, I believe you want to use the afterChange event to act on the active element after it has been made visible.
Check out the docs and examples, especially the section titled "Events" on Slick page: http://kenwheeler.github.io/slick/
And I think you don't want to use title attribute for this because that is for tooltips. I recommend data-* attributes instead. And element IDs should generally start with a letter and not a number (was required in HTML4 and makes life easier when mapping IDs to JavaScript variables; though if you are using HTML5 I think this requirement is no longer in effect).
HTML
<div id="carousel">
<div data-content-id="content1">
Selector 1 </div>
<div data-content-id="content2">
Selector 2 </div>
<div data-content-id="content3">
Selector 3 </div>
</div>
<ul class="content">
<li id="content1">Content 1</li>
<li id="content2">Content 2</li>
<li id="content3">Content 3</li>
</ul>
JavaScript
$('#carousel').on('afterChange', function(event, slick, currentSlide) {
// get the associated content id
var contentId = $(slick.$slides.get(currentSlide)).data("content-id");
if(contentId && contentId.length)
{
var $content = $("#" + contentId);
$(".content>li").removeClass("open"); // hide other content
$content.addClass("open"); // show target content, or whatever...
}
});
I have found a solution:
$('.slider').on('afterChange', function(event, slick, currentSlide, nextSlide){
var contentId= $(slick.$slides.get(currentSlide)).data('content');
if(contentId)
{
$(".content li").removeClass('open');
$('#' + contentId).addClass('open');
}
});

Reveal.js presentation full screen from JHipster

I am trying to show a reveal.js presentation full screen from a JHipster single page app. The reveal.js example below works fine inside JHipster, it's just not full screen. It can be made full screen by creating a second page, but given JHipster's design as a single page app things get messy with grunt and the production profile. I've also tried hiding the app menu bar and footer div elements but the reveal presentation still has padding around it. Ideally a full-screen view can configured.
Simple Reveal slide
<div ng-cloak>
<div class="reveal">
<div class="slides">
<section data-background="#faebd7">
<h1>FULL SCREEN SLIDE</h1>
</section>
</div>
</div>
</div>
A second page is the way to go and below is a way to by-pass optimizations made by JHipster's production build.
JHipster's production build only optimizes files under src/main/webapp/scripts and src/main/webapp/assets directories. So, put your presentation files including revealjs under another folder (e.g. src/main/webapp/slides) and use a simple link from your app to load the presentation.
This is what is done for swagger-ui under src/main/webapp/swagger-ui
I solved the problem while keeping it a single page app. Previously I tried hiding elements of the page that prevented full-screen, but padding on the main div container was preventing full screen. The solution was to create a second ui-view div designed for full screen and hide all other div elements.
Solution:
1. Add "hidewhenfullscreen" class to the elements to hide.
2. Use javascript to show/hide elements
3. Add a second fullpage ui-view designed for full screen
4. Reference the fullpage ui-view from the controller
index.html
<div ng-show="{{ENV === 'dev'}}" class="development hidewhenfullscreen" ng-cloak=""></div>
<div ui-view="navbar" ng-cloak="" class="hidewhenfullscreen"></div>
<div class="container hidewhenfullscreen">
<div class="well" ui-view="content"></div>
<div class="footer">
<p translate="footer">This is your footer</p>
</div>
</div>
JavaScript to show/hide elements
<script>
hide(document.querySelectorAll('.hidewhenfullscreen'));
function hide (elements) {
elements = elements.length ? elements : [elements];
for (var index = 0; index < elements.length; index++) {
elements[index].style.display = 'none';
}
}
function show (elements) {
elements = elements.length ? elements : [elements];
for (var index = 0; index < elements.length; index++) {
elements[index].style.display = 'block';
}
}
</script>
JavaScript controller
.state('show', {
parent: '',
url: '/show/{presentationName}',
data: {
authorities: [], // none, wide open
pageTitle: 'page title'
},
views: {
'fullpage#': {
templateUrl: 'scripts/show/show.html',
controller: 'ShowController'
}
}
})
The page has a single small "Home" href that calls the show function. This way the user can go back and forth between the full-screen Reveal presentation and the standard jHipster view.
show.html
<div ng-show="{{ENV === 'dev'}}" class="development"></div>
<div class="miniMenu" id="miniMenu" ng-cloak="">
Home
</div>
<div class="reveal">
<div class="slides">
<section data-background={{getBackgroundURI($index)}} ng-repeat="slide in slides track by $index">
<div ng-bind-html="getContent($index)"></div>
</section>
</div>
</div>
For completeness, creating a second page can work but I don't think it is worth the added complexity. A two-page solution worked fine in the development profile, but the production profile had issues with caching shared css files, js files and fonts. With time and energy, I am sure the proper grunt configuration can be made to work, although the idea seems to counter the single page design concept. While in Rome, do as the Romans do.

Image Metadata: altText , height in Orchard CMS

For many of Custom Types created, we have a Query for them. These queries are being used by Projection Widgets (Within Zones).
Few of the custom types have Media Picker field.The Layout type I used for my Queries is the Shape type as seen below:
=>>> Queries:
=>>> Layout:
. I have followed the steps from here.. I specified the name of the shape as : UpcomingHighlightsImages as seen below:
and then included the view: UpcomingHighlightsImages.cshtml in my Themes/MyFirstTheme/Views folder.
Everything works fine upto here.
In the View, problem is that there is NO way to read the Image Metadata such as altText, altHeight etc... Neither there seems to be a way to set these metadata firstly in Orchard itself.
#using Orchard.ContentManagement
#using Orchard.Core.Title.Models
#using Orchard.Fields.Fields
#using Orchard.Taxonomies.Fields
#using Orchard.Core.Common.Fields;
#using Orchard.MediaLibrary.Fields;
#{
var HighlightItems = ((IEnumerable<ContentItem>)Model.ContentItems).ToList();
}
#foreach (var item in HighlightItems)
{
String LinkUrl = ((TextField)item.Parts.SelectMany(x => x.Fields).Single(x => x.Name == "LinkURL")).Value;
String ImagePath = ((MediaLibraryPickerField)item.Parts.SelectMany(x => x.Fields).Single(x => x.Name == "MainImage")).MediaParts.First().MediaUrl;
<div>
<a target="_blank" href="#LinkUrl">
<img src="#ImagePath" />
</a>
</div>
}
So, as seen in above code and the tag, I need:
Set the altText, altHeight property of Image in ORchard CMS
Read these in my view , the way I read LinkUrl and ImagePath
Please guide me !
See how you got the first media part in that ImagePath expression? Well, then you can take that part and get Title, Caption, AlternateText, etc. from it. You can also As<ImagePart>() it and get its Width and Height.

Orchard CMS: Logon Page doesn't work with my custom layout

I am very new to Orchard.
I have created a new theme, based on the Minty theme. The only real change is the layout, where I have adapted the html from an existing asp.net masterpage to match the orchard style razor layout.cshtml. I have experience with MVC and razor, so no problem on that side... unless I have missed something vital.
The problem is the login page. Clicking the sign in link takes me to the correct url without errors, but not login form gets rendered. I have checked that this is the case by Inspecting Element in google chrome.
I am aware that setting up widgets, etc, I can make content appear. However, I can't find how the login form gets inserted when the login url gets requested. I presume it uses the Orchard.Users module, but not sure how. Does it need a specific zone? I can't see why, but see how else.
As a result, I can't solve my problem...
Any pointers?
Any books or other learning media?
The code for my layout.cshtml is:
#functions {
// To support the layout classifaction below. Implementing as a razor function because we can, could otherwise be a Func<string[], string, string> in the code block following.
string CalcuClassify(string[] zoneNames, string classNamePrefix) {
var zoneCounter = 0;
var zoneNumsFilled = string.Join("", zoneNames.Select(zoneName => { ++zoneCounter; return Model[zoneName] != null ? zoneCounter.ToString() : "";}).ToArray());
return HasText(zoneNumsFilled) ? classNamePrefix + zoneNumsFilled : "";
}
}

PS: the branding and badge of honour are commented out as I am only enabling bit by bit to eliminate the source of errors. It will be in the live site.
ADDENDUM:
See Bertrand Le Roy's answer below. The Orchard.Users module requires a Content zone with a Capital C. That instantly cured the problem.
I added this as Bertrand's response was tentative, and I wanted to reinforce that the problem was the name of the zone.
In Orchard.Users, look for Controllers/AccountController.cs. In there, there is a LogOn action. It creates a LogOn shape that it then puts in a shape result. This then gets resolved as the Views/LogOn.cshtml template (which you can override in your theme by just dropping a file with the same name in there, for example a copy of the original that you can tweak). The LogOn template will be rendered within the theme's layout, in the Content zone. Does this answer your question?
I think the mistake you made was to name your Content zone content (notice the casing).

Grails search mechanism

I have the folowing gsp page:
<g:form controller="??" action="??">
<h1>Search</h1>
<g:submitButton name="search" value="Search"/>
<div id="resultsHere">
</div>
</g:form>
What i want to do is, everytime "Search is clicked", the database is searched for that record, lets imagine im looking for book titles. So everytime i write a title, the database finds the books and print every data related to the books. How can i do that=?
My idea is having something similar to this in the div:
<ul>
<g:each in="${bookList}">
<li>Name: ${it.name}, Locale: ${it.isbn}</li>
</g:each>
</ul>
So the point is, when the search button is clicked, the controller that handle that action should redirect the page to the same page, and pass the filtered list of books so it can be printed in the <g:each in="${bookList}"> tag.
I would like opinions about this being the best solution in this case. I could also render the results in the page directly, but i would like to do some css for the lookings so i think that wont be a good idea using render. Any help would be apreciated, and if possible, some lights with the code (specially the filtering part).
I would have one action in your controller, and render out the list.
ie: as pseudo-code (and not complete)
BookController {
def search = {SearchComamnd search ->
def books = []
if(search) {
books = Book.createCritera().list {
and {
title(search.title)
author(search.title)
}
}
}
render [ books:books ]
}
class SearchCommand {
def author
def title
}
}
and then when in your view
<g:form controller="??" action="??">
<h1>Search</h1>
<g:submitButton name="search" value="Search"/>
</g:form>
<g:each in="${books}">
<li class="book">Name: ${it.name}, Locale: ${it.isbn}</li>
</g:each>
you can now use css li.book to decorate the entry.
