So the problem is that I can not show even elements in my view file. I have the following code in my view file:


    {{range $i, $stream := .d}}
        {{if $i % 2 == 0}}
            {{$stream.Channel.Status}}
        {{end}}
    {{end}}

From the docs I've read that "You CANNOT use conditional expressions in if. Only boolean values are acceptable."

So how can I implement it?

Thanks in advance

You could always produce the filtered results back in your Go code before this executes and remove the conditional altogether. – evanmcdonnal Jun 25 '15 at 22:41
Use `*template.Template`'s `Funcs` method to define a function that tests for even numbers and use that in your if statement. – thwd Jun 26 '15 at 09:50
