How Can I Handle Nil Objects and Conditional Rendering in Go Templates?

Using Nil Logic in Go Templates

In Go templates, displaying content based on object properties is a common task. When an object is nil, you may want to show default content, otherwise, showing content based on a specific property value.

To achieve this, you can leverage Go's built-in nil logic. The following code block demonstrates how:

{{if not .}}
   <!-- Default content -->
{{else if eq .MetaValue "some-x"}}
   <!-- Content for 'some-x' property -->
{{else}}
   <!-- Content for all other cases -->
{{end}}

In this code:

• {{if not .}} checks if the object pointed by ., which represents the template data, is nil or an empty value.
• {{else if eq .MetaValue "some-x"}} checks if the MetaValue property of the object being nil checked is equal to "some-x".
• {{else}} executes if neither of the above conditions are met.
