View Templates

Available Templates

| Template | Description | Use Case | |----------|-------------|----------| | default | Standard HTML structure | General purpose | | bootstrap | Bootstrap 5 components | Modern web apps | | tailwind | Tailwind CSS classes | Utility-first design | | ajax | AJAX-enabled views | Dynamic updates | | mobile | Mobile-optimized | Responsive design | | print | Print-friendly layout | Reports | | email | Email template | Notifications |

Template Structure

Templates are located in:

~/.commandbox/cfml/modules/wheels-cli/templates/views/
├── default/
│   ├── index.cfm
│   ├── show.cfm
│   ├── new.cfm
│   ├── edit.cfm
│   └── _form.cfm
├── bootstrap/
└── custom/

Partial Views

Naming Convention

Partials start with underscore:

• _form.cfm - Form partial
• _item.cfm - List item partial
• _sidebar.cfm - Sidebar partial

Generate Partials

wheels generate view shared header,footer,navigation --partial

Using Partials

<!--- In layout or view --->
#includePartial("/shared/header")#
#includePartial("/products/form", product=product)#
#includePartial(partial="item", query=products)#

Layout Integration

With Layout (default)

<!--- Generated view assumes layout wrapper --->
<h1>Page Title</h1>
<p>Content here</p>

Without Layout

wheels generate view products standalone --layout=false

<!DOCTYPE html>
<html>
<head>
    <title>Standalone View</title>
</head>
<body>
    <h1>Products</h1>
    <!-- Complete HTML structure -->
</body>
</html>

Custom Formats

HTML Format

wheels generate view products index --format=html

Creates: /views/products/index.html

Custom Extensions

wheels generate view emails welcome --format=txt

Creates: /views/emails/welcome.txt

Ajax Views

Generate AJAX View

wheels generate view products search --template=ajax

AJAX Template Example

<cfif isAjax()>
    <!--- Return just the content --->
    <cfoutput query="products">
        <div class="search-result">
            <h3>#products.name#</h3>
            <p>#products.description#</p>
        </div>
    </cfoutput>
<cfelse>
    <!--- Include full page structure --->
    <div id="search-results">
        <cfinclude template="_results.cfm">
    </div>
</cfif>

Form Helpers

Standard Form

#startFormTag(action="create", method="post", class="needs-validation")#
    #textField(objectName="product", property="name", label="Product Name", class="form-control", required=true)#
    #textArea(objectName="product", property="description", label="Description", class="form-control", rows=5)#
    #select(objectName="product", property="categoryId", options=categories, label="Category", class="form-control")#
    #submitTag(value="Save Product", class="btn btn-primary")#
#endFormTag()#

File Upload Form

#startFormTag(action="upload", multipart=true)#
    #fileFieldTag(name="productImage", label="Product Image", accept="image/*", class="form-control")#
    #submitTag(value="Upload", class="btn btn-primary")#
#endFormTag()#

Responsive Design

Mobile-First Template

wheels generate view products index --template=mobile

<div class="container-fluid">
    <div class="row">
        <div class="col-12">
            <h1 class="h3">Products</h1>
        </div>
    </div>
    
    <div class="row">
        <cfoutput query="products">
            <div class="col-12 col-md-6 col-lg-4 mb-3">
                <div class="card h-100">
                    <div class="card-body">
                        <h5 class="card-title">#products.name#</h5>
                        <p class="card-text">#products.description#</p>
                        #linkTo(text="View", action="show", key=products.id, class="btn btn-primary btn-sm")#
                    </div>
                </div>
            </div>
        </cfoutput>
    </div>
</div>

Localization

Generate Localized Views

wheels generate view products index --locale=es

Creates: /views/products/index_es.cfm

Localized Content

<h1>#l("products.title")#</h1>
<p>#l("products.description")#</p>

#linkTo(text=l("buttons.new"), action="new", class="btn btn-primary")#

Testing Views

Generate View Tests

wheels generate view products index
wheels generate test view products/index

View Test Example

component extends="wheels.Test" {
    
    function test_index_displays_products() {
        products = model("Product").findAll(maxRows=5);
        result = renderView(view="/products/index", products=products, layout=false);
        
        assert(Find("<h1>Products</h1>", result));
        assert(Find("New Product", result));
        assertEquals(products.recordCount, ListLen(result, "<tr>") - 1);
    }
    
}

Performance Optimization

Caching Views

<cfcache action="cache" timespan="#CreateTimeSpan(0,1,0,0)#">
    <!--- Expensive view content --->
    #includePartial("products/list", products=products)#
</cfcache>

Lazy Loading

<div class="products-container" data-lazy-load="/products/more">
    <!--- Initial content --->
</div>

<script>
// Implement lazy loading
</script>

Best Practices

1. Keep views simple and focused on presentation
2. Use partials for reusable components
3. Move complex logic to helpers or controllers
4. Follow naming conventions consistently
5. Use semantic HTML markup
6. Include accessibility attributes
7. Optimize for performance with caching
8. Test views with various data states

Common Patterns

Empty State

<cfif products.recordCount>
    <!--- Show products --->
<cfelse>
    <div class="empty-state">
        <h2>No products found</h2>
        <p>Get started by adding your first product.</p>
        #linkTo(text="Add Product", action="new", class="btn btn-primary")#
    </div>
</cfif>

Loading State

<div class="loading-spinner" style="display: none;">
    <i class="fa fa-spinner fa-spin"></i> Loading...
</div>

Error State

<cfif structKeyExists(variables, "error")>
    <div class="alert alert-danger">
        <strong>Error:</strong> #error.message#
    </div>
</cfif>
