Golang array with forEach to fill model-CodePudding

I have a dynamic import where people can choose what field to use for a specific row. In Golang, I receive this array obviously and want to loop through the imported CSV and add each row to a specific part of the model. See my current code below.

applicant := models.Applicant{
    Prefix:                        "",
    FirstName:                     "",
    LastName:                      "",
    Email:                         "",
    Telephone:                     "",
    Mobile:                        "",
    Gender:                        "",
    CreatedAt:                     time.Time{},
    UpdatedAt:                     nil,
    DeletedAt:                     nil,
}

row := 0
splitted := strings.Split(details[0], ",")
data := strings.Split(rec[0], ";")

for i := range splitted {
    if splitted[i] != "" {    
        applicant[splitted[i]] = data[row]
    }

    row  
}

Obviously this won't work because I cannot say (in my for loop):

applicant[splitted[i]] = data[row]

Because a model does not support indexing. I have been Googling for hours but I am unable to find a solution to my problem.

Can anyone please help me out and tell me how I can make this work?

CodePudding user response：

If that model is an arbitrary structure, you might need to use reflection on order to modify one of its fields.

See for instance this answer, which adds a SetStringField2() method, using a Value.SetString() call to modify the (string) value of a field.

Example:

    a := struct {
        Name string
    }{}

    // works
    reflect.ValueOf(&a).Elem().FieldByName("Name").SetString("Hello")
    fmt.Printf("%#v\n", a)
