Get value by key from map about pongo2

[denisgrib]

not work, where I can see stupid example?

I need

    for _, key := range gameByViewers {
        fmt.Println(data[key]["name"])
    }

in template

Simply try {% if !mymap.Key %}Key does not exist{% else %}Does exist{% endif %}. Does this work for you? Worked for me.

BTW, instead of using the ! operator, you can use the not keyword as well (if not mymap.Key).

Of course, it should work the other way around as well (not using the not or !-operator).

Working example:

func main() {
        result := pongo2.RenderTemplateString("{% if not mymap.Key %}Key does not exist{% else %}Does exist{% endif %}", pongo2.Context{"mymap": map[string]int{"Key": 1}})
        fmt.Println(result)
}

or

func main() {
        result := pongo2.RenderTemplateString("{% if mymap.Key %}Key does exist{% else %}Does not exist{% endif %}", pongo2.Context{"mymap": map[string]int{}})
        fmt.Println(result)
}

Both works.
