trying to initiate with mock values
Use the address of variables. For example,
package main
import (
"fmt"
)
func main() {
type ValidateTemplateQuery struct {
TemplateURL *string `json:"template_url" valid:"optional"`
TemplateBody *string `json:"template_body" valid:"optional"`
}
url := "TemplateURLValue"
body := "TemplateBodyValue"
action := &ValidateTemplateQuery{
TemplateURL: &url,
TemplateBody: &body,
}
fmt.Println(action, *action.TemplateURL, *action.TemplateBody)
}
Playground: https://play.golang.org/p/LZKV2LZ4KiE
Output:
&{0x40c138 0x40c140} TemplateURLValue TemplateBodyValue
The Go Programming Language Specification
Address operators
For an operand x of type T, the address operation &x generates a
pointer of type *T to x. The operand must be addressable, that is,
either a variable, pointer indirection, or slice indexing operation;
or a field selector of an addressable struct operand; or an array
indexing operation of an addressable array. As an exception to the
addressability requirement, x may also be a (possibly parenthesized)
composite literal. If the evaluation of x would cause a run-time
panic, then the evaluation of &x does too.
