templates in html

[Денис Мухортов]

I need to pass data from the map[string]interface{} through the template

I dont know why, but I catch the error:
template: stone-card.html:2: function "stoneShop" not defined.

Code in go:

files := []string{

                dirWithHTML + "index.html",

                dirWithHTML + "stone-card.html",

            }

            tmp, err := template.ParseFiles(files...)

            if err != nil {

                fmt.Println(err)

            }

            err = tmp.Execute(w, block)

            if err != nil {

                log.Fatal(err)

            }

            stoneShop := stones()

            err = tmp.ExecuteTemplate(w, "stone", stoneShop)
            // var stoneShop map[string]interface{}

            if err != nil {

                log.Print(err)

            }
Template Code:

{{define "stone"}}

{{range $key, $value := stoneShop}}

<li class="card {{$value.Rare}}">

    <div class="side1">

      <img class="card__img" src={{$value.URL}} alt="{{$value.Name}}">

    </div>

    <div class="side2">

      <h3 class="card__name">

        {{$value.Name}}

      </h3>

      <p class="card__desc">

        {{$value.Description}}

      </p>

      <div class="card__rare">

        {{$value.Rare}}

      </div>

      <div class="buy">

        <button class="btn btn-reset">Купить</button>

        <div class="item-price">{{$value.Price}} C</div>

      </div>

    </div>

</li>

{{end}}

{{end}}

Have a look at this:

https://pkg.go.dev/html/template#Template.Funcs

You need to provide a map of function names to function references to the template engine, otherwise, it has no idea what "stoneShop" is, because all it sees is an interface{} and has no context to know that it's a function. This data argument is explored via reflection, so if you reference ".Something", the template engine will look in data for a field with that name.

The function map that I linked above is where you would provide your "stoneShop" function.
