I use the Handlebars template engine:
`{{#each classes}}
<div class="col_4">
<h4>{{this.title}}</h4>
<p>{{this.description}}</p>
<a class="button" href="/classes/{{_id}}/details">View Class</a>
</div>
{{/each}}`
Why is it not possible to address title and description as individual fields of this?
If I use "this" like this:
{{#each classes}}
<div class="col_4">
<h4>{{this}}</h4>
<p>{{this}}</p>
<a class="button" href="/classes/{{_id}}/details">View Class</a>
</div>
{{/each}}
all fields are displayed merged.
The following code works with an earlier version:
{{#each classes }}
<div class="col_4">
<h4>{{title}}</h4>
<p>{{description}}</p>
<a class="button" href="/classes/{{_id}}/details">View Class</a>
</div>
{{/each}}

I know my question seems weird but since I'm new when using ghost with handlebars language, I'm quite confused as to where I can find some of this data bind such as title, #site.logo, etc. I try to find it inside casper template but I still not find it, this is the example of the code image inside casper theme
if you ask why I try to find it, I want to try add some of the content inside it or at least I want to take a look what kind of data bind that casper have or provided.
for example in this post.hbs you can see that there is a lot of data bind in here, but I just can't find what else the data bind they provided,
{{!< default}}
{{!-- The tag above means: insert everything in this file

can someone help me to point it out where I can find a list of data bind they provided? I'm quite confused to understand it
they call that Helpers and you can find the full list here:
Themes documentation
There is several categories: Functionnal, Data, Utility, Extra... And you find several inside with a description for each.

Are you looking for a particular piece of data that you've put into Ghost admin? {{#site.logo}} and {{#site.title}} is how you out put those data values 😊
I have a row that needs to be displayed/hidden based on a variable as follows:-
{{#if ShowCamValue == true}}
<div class="row">
<div class="cell">
CAM (SF)
</div>
{{#each Properties}}
<div class="cell">
{{Property.Cam}}
</div>
{{/each}}
</div>
{{/if}}
Even though, this is true(i.e. ShowCamValue equals "true") it still doesn't display the row. Any ideas what's going on.
You just do,
{{#if ShowCamValue}}
instead of == that's not valid in handlebar.
and also check each helper syntax, you haven't defined Property. you can use this
{{#each Properties}}
<div class="cell">
{{this.Cam}}
</div>
{{/each}}
tasks is from an api call. The list is showing up but no dragging is happening. The tasks are all showing up as one block div#object.sortable.target when i hover using javascript console.
<div class="col-md-4">
<div class="list-pair col-sm-12">
{{#each tasks}}
<div class="sortable target" id="object">
{{#sortable items=tasks animation="100" ghostClass="sortable-ghost" }}
<!--<div class="list-group-item"> -->
{{title}}
{{/sortable}}
</div>
<!-- </div> -->
{{else}}
<p>List is empty.</p>
{{/each}}
</div></div>
server code:
Sortable.collections = ['tasks'];
I think you should not use {{#each}} when you use {{#sortable}}
Is there a way to call a template on other template, but excluding it from the CSS selectors and all?
This does not work, the {{> map_template}} looks weird:
<template name="main">
<div class="containerMain">
<div id="bl-main" class="bl-main">
<section>
<div class="bl-box">
<img src="images/logo.png">
</div>
<div class="bl-content">
<h2>Pa' Donde Menu</h2>
{{#each mostrarEvento}}
{{> Evento}}
{{/each}}
{{> map_template}}
</div>
<span class="bl-icon bl-icon-close"></span>
</section>
</div>
</div>
</template>
This works:
<template name="main">
{{> map_template}}
<div class="containerMain">
<div id="bl-main" class="bl-main">
<section>
<div class="bl-box">
<img src="images/logo.png">
</div>
<div class="bl-content">
<h2>Pa' Donde Menu</h2>
{{#each mostrarEvento}}
{{> Evento}}
{{/each}}
</div>
<span class="bl-icon bl-icon-close"></span>
</section>
</div>
</div>
</template>
So is there a way to use {{> map_Template}} inside the <div class="containerMain">, but without applying the CSS and all that stuff?
I'm not a web whiz, but off the top of my head, you need to create a new template for the {{> map_template}}. Make sure to name the class inside map_template and then create a css template inside your style.css or wherever you are getting your CSS from.
Your CSS should end up something like:
.map-template{
//style stuff
}
Where {map-template} matches your class name.
I used this question to try to piece together a solution: How to prevent child element from inheriting CSS styles
Sorry if that isn't quite what you are looking for.
Is it possible to dynamically set the text color of a input field based on a handlebars.js template value?
I am initially creating my html using this template:
<div class="board">
<div class="header">
<span class="name">Project</span>
<span class="status">Status</span>
</div>
{{#each projects}}
{{> project}}
{{/each}}
</div>
Where projects is an object read from a db. The resulting html (what gets rendered on the page not what is in my html) for each project looks something like this:
<div class="project">
<span class="name">FOO</span>
<span class="status">OK</span>
</div>
<div class="project">
<span class="name">BAR</span>
<span class="status">NOTOK</span>
</div>
I would like to render this html with the colour of the OK & NOTOK text set dynamically.
I already have a handlebars helper function that will successfully return the correct colour code based on each option and I can call this using:
{{getStatusColor currentStatus}}
What I would like to do is put this function call directly into the css itself, a bit like:
font-color: {{getStatusColor currentStatus}}
But obviously this doesn't work. This function does feel like the right approach though but where can I use it to format the text correctly on the page?
Answering my own question: The template needed to be expanded (from {{> projects}}) to allow for conditional rendering.
<div class="board">
<div class="header">
<span class="name">Project</span>
<span class="status">Status</span>
</div>
{{#each projects}}
<div class="project">
<span class="name">{{name}}</span>
<span class="status" style="color:{{getStatusColor status}}">{{status}}</span>
</div>
{{/each}}
</div>
For completeness, the helper function getStatusColor looks like this:
Handlebars.registerHelper('getStatusColor', function(status) {
switch (status) {
case "GOOD" : {
return 'green';
}
break;
case "BAD" : {
return 'red';
}
break;
default : {
...etc.;
}
});
UPDATE:
In the interests of honesty, I should confess I totally missed that I already had this expanded template in my code and that {{> projects}} was pointing to this. I should have just added the style="color:{{getStatusColor status}}" attribute directly into the referenced project template. So, as much for my benefit as others, the final, working, HTML:
<template name="foo">
<div class="board">
<div class="header">
<span class="name">Project</span>
<span class="status">Status</span>
</div>
{{#each projects}}
{{> project}}
{{/each}}
</div>
</template>
<template name="project">
<div class="project {{selected}}">
<span class="name">{{name}}</span>
<span class="status"style="color:{{getStatusColor status}}">{{status}}</span>
</div>
</template>
