我有两个模型,一个用户模型和一个课程模型

用户架构如下所示:

create_table "users", force: true do |t|
    t.string   "username",                        default: "",    null: false
    t.string   "first_name",                      default: "",    null: false
    t.string   "last_name",                       default: "",    null: false
    t.string   "password_digest",                 default: "",    null: false
    t.string   "email",                           default: "",    null: false
    t.string   "email_unconfirmed",               default: "",    null: false
    t.string   "email_verification_token",        default: "",    null: false
    t.string   "password_reset_token",            default: "",    null: false
    t.datetime "password_reset_token_expires_at"
    t.boolean  "admin",                           default: false
    t.boolean  "teacher",                         default: false
    t.datetime "created_at"
    t.datetime "updated_at"
end

课程架构如下所示:

create_table "courses", force: true do |t|
    t.integer  "teacher_id" …

我使用了来自aweber的代码，该代码将用户信息从注册传递到了下一页，这是来自aweber的代码

<script type="text/javascript"> 
    var formData = function(){
        var query_string = (location.search)?((location.search.indexOf('#') != -1) ? location.search.substring(1, location.search.indexOf('#')) : location.search.substring(1)) : '';
        var elements = [];
        if(query_string){
            var pairs = query_string.split("&");
            for(i in pairs) { 
                if (typeof pairs[i] == 'string') {
                    var tmp = pairs[i].split("="); 
                    var queryKey = unescape(tmp[0]);
                    queryKey = (queryKey.charAt(0) == 'c') ? queryKey.replace(/\s/g, "_") : queryKey;elements[queryKey] = unescape(tmp[1]);
                }
            }
        }
        return{display: function(key){if(elements[key]){document.write(elements[key]);
    }else {
        document.write("<!--If desired, replace everything between these quotes with a default in case there is …
