Can't update table in mysql in a Grails application - mysql

Question

I have this weird problem. I have a User domain class in a Grails app. The class is as follows:
class User {
transient springSecurityService
String username
String name
String password
String email
String company
Date activationDate
String contactPhone
boolean enabled
boolean passwordExpired = false
boolean accountExpired
boolean accountLocked
boolean isDeleted=false
boolean isPrimary
String jobTitle
String jobFunction
String deskPhone
String mobile
String profilePicURL
boolean isLinkExpired=false
UserType userType
Date dateCreated
Date lastUpdated
static constraints = {
password nullable: true
company nullable: true
email blank: false, unique: true
name nullable: true
activationDate nullable:true
username nullable: true
enabled nullable: false
isDeleted nullable: false
passwordExpired nullable: false
jobFunction nullable:true
jobTitle nullable:true
contactPhone nullable:true
mobile nullable:true
profilePicURL nullable:true
deskPhone nullable:true
userType nullable:true
}
static auditable = true
static mapping = {
password column: '`password`'
tablePerHierarchy false
cache true
}
Set<Role> getAuthorities() {
UserRole.findAllByUser(this).collect { it.role } as Set
}
And there is a method activeDeactiveUser which enables/disables user authorization for some functionality as follows:
def activeDeactiveUser(String username) {
def user = User.findByUsername(username)
if (user.enabled == false)
user.enabled = true
else
user.enabled = false
if (user.validate()) {
user.save(flush: true, failOnError: true)
} else {
user.errors.allErrors.each {
print it
}
}
def userJson = new JSONObject()
userJson.put("isEnabled", user.enabled)
return userJson
}
When the app is running on localhost, the table is updating fine. But when the same code is running on server, the table fails to update. I don't know why it's behaving like this.
The app isn't raising any exception on the save method on localhost. May be the problem is with different versions of mysql on my machine and the server. Is there any the to debug the app while it is running on the server?
The app is hosted in an AWS EC2 instance running Ubuntu 14.04 and Grails version 2.4.3. The database is stored in an AWS RDS instance running mysql 5.5.40.

there are many reasons for it - I think you need to provide more information for yourself and in this thread so we can help.
I suggest, first add log information by one of the options:
you can add logSql to dataSource file:
dataSource {
logSql = true
}
to produce far more readable SQL commands than simply logSql would do add the following properties in DataSource.groovy:
hibernate {
format_sql = true
use_sql_comments = true
}
Then, add the following log4j settings to Config.groovy:
log4j = {
debug 'org.hibernate.SQL'
trace 'org.hibernate.type'
}
The first setting logs the SQL commands, the second one logs the bound parameters and the bindings of the result set.
the issue can also be related to schema update - so maybe your local DB schema is not in sync with server one. you ned to check field type and constraints.
