Request Context in Go Templates

Go HTML templates provide a powerful way to render dynamic content, but their inability to access the request context presents a challenge when conditionally displaying elements based on user-specific information.

One common use case is to determine if the current user is an administrator and display specific options accordingly. However, the template engine does not directly interact with the request, making it impossible to check this condition.

While there are suggestions to use pipelines or handler/controllers for logic and rendering, respectively, these solutions may not align with specific application requirements. To address this issue, you can leverage a technique involving a custom data type that embeds both the request context and data to be rendered.

For instance, you can define a TemplateData struct that encapsulates a Content struct and a Context struct. This allows you to pass the request context to the template while still maintaining a clear separation between data and context.

By constructing your templates using this custom data type, you can access the request information within the template, including user information. This provides a convenient and flexible method to conditionally display elements based on the request context without compromising the logical separation of your application.
