I have a map
of values that looks like this:
vals := map[string]interface{}{"foo": 1, "bar": 2, "baz": 7}
data := map[string]interface{}{"bat": "obj", "values": vals}
What should my template look like to generate the following string (note the correct comma usage)?
SET obj.foo=1, obj.bar=2, obj.baz=7
I started with this as my template:
SET {{range $i, $v := .values}} {{.bat}}.{{$i}}={{$v}},{{end}}
But that just prints out
SET
And even if that did work, the commas would be incorrect. I then tried to use a custom function to format the map, but I couldn't get the template to ever call my function. None of the following seemed to work:
SET {{.MyFunction .values}}
SET {{call .MyFunction .values}}
SET {{call MyFunction .values}}
when MyFunction was defined as:
func MyFunction(data map[string]interface{}) string {
fmt.PrintLn('i was called!')
return "foo"
}
And I'm executing the templates using a helper function that looks like this:
func useTemplate(name string, data interface{}) string {
out := new(bytes.Buffer)
templates[name].Execute(out, data)
return string(out.Bytes())
}
Thanks!
