mysql timestamp error with time.Now() golang - go

Question

How to save time.Now() in mysql table, column name as created_at timestamp null.
I am getting error :
Error:Error 1292: Incorrect datetime value: '2017-08-05 19:06:14.190 +0000' for column 'created_at' at row 1
More Information as asked :- ( I am using fragmenta cms, so all reference code with their line number is given below )
Table schema :-
mysql> describe users;
+----------------------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+----------------------+--------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| created_at | timestamp | YES | | NULL | |
| updated_at | timestamp | YES | | NULL | |
| status | int(11) | YES | | NULL | |
| role | int(11) | YES | | NULL | |
| name | varchar(250) | YES | | NULL | |
| email | varchar(250) | YES | | NULL | |
| title | varchar(250) | YES | | NULL | |
| summary | text | YES | | NULL | |

Code that is running it to save :-
At line no. 62 here ( https://github.com/fragmenta/fragmenta-cms/blob/master/src/pages/actions/setup.go#L62 )
It calls code
user := users.New()
in Line no. 51 at file here ( https://github.com/fragmenta/fragmenta-cms/blob/master/src/users/query.go#L51 )
New() function is setup.
Which is like :-
func New() *User {
user := &User{}
user.CreatedAt = time.Now()
user.UpdatedAt = time.Now()
user.TableName = TableName
user.KeyName = KeyName
user.Status = status.Draft
return user
}
and their connecting / mysql opening pattern is located here ( https://github.com/fragmenta/query/blob/master/adapters/database_mysql.go#L23 ) .

Answer 1

There is a bug in https://github.com/fragmenta/query. The TimeString method in query/adapters/database.go is not valid for all DBMS adapters.
// TimeString - given a time, return the standard string representation
func (db *Adapter) TimeString(t time.Time) string {
return t.Format("2006-01-02 15:04:05.000 -0700")
}
It's not valid for a MySQL timestamp: MySQL 5.7 Reference Manual, 11.3.1 The DATE, DATETIME, and TIMESTAMP Types. The MySQL TimeString method in query/adapters/database_mysql.go should be:
// TimeString - given a time, return the MySQL standard string representation
func (db *MysqlAdapter) TimeString(t time.Time) string {
return t.Format("2006-01-02 15:04:05.999999")
}

Answer 2

You are trying to insert it using a string query.go:36:
now := query.TimeString(time.Now().UTC())
that is generated by the package that you are using database.go:59:
return t.Format("2006-01-02 15:04:05.000 -0700")
MySQL expects it to be in the pattern of yyyy-MM-dd hh:mm:ss, use the following snippet to apply the pattern to you current Time.time object:
now := time.Now().UTC().Format("2006-01-02 03:04:05")
Anyway, why not to use the SQL function NOW() when inserting the record ?
