Dear friends i am a newbie in yii and started learning the framework using the book Webapplication development using yii and PHP. the problem is with migration code given in the chapter 5 of the book.
public function safeUp()
{
try{
//create the issue table
$this->createTable('tbl_issue', array(
'id' => 'pk',
'name' => 'string NOT NULL',
'description' => 'text',
'project_id' => 'int(11) DEFAULT NULL',
'type_id' => 'int(11) DEFAULT NULL',
'status_id' => 'int(11) DEFAULT NULL',
'owner_id' => 'int(11) DEFAULT NULL',
'requester_id' => 'int(11) DEFAULT NULL',
'create_time' => 'datetime DEFAULT NULL',
'create_user_id' => 'int(11) DEFAULT NULL',
'update_time' => 'datetime DEFAULT NULL',
'update_user_id' => 'int(11) DEFAULT NULL',
), 'ENGINE=InnoDB');
//create the user table
$this->createTable('tbl_user', array(
'id' => 'pk',
'username' => 'string NOT NULL',
'email' => 'string NOT NULL',
'password' => 'string NOT NULL',
'last_login_time' => 'datetime DEFAULT NULL',
'create_time' => 'datetime DEFAULT NULL',
'create_user_id' => 'int(11) DEFAULT NULL',
'update_time' => 'datetime DEFAULT NULL',
'update_user_id' => 'int(11) DEFAULT NULL',
), 'ENGINE=InnoDB');
//relationship between projects and users
$this->createTable('tbl_project_user_assignment', array(
'project_id' => 'int(11) NOT NULL',
'user_id' => 'int(11) NOT NULL',
'PRIMARY KEY (`project_id`,`user_id`)',
), 'ENGINE=InnoDB');
//foreign key relationships
//the tbl_issue.project_id is a reference to tbl_project.id
$this->addForeignKey("fk_issue_project", "tbl_issue", "project_id", "tbl_project", "id", "CASCADE", "RESTRICT");
//the tbl_issue.owner_id is a reference to tbl_user.id
$this->addForeignKey("fk_issue_owner", "tbl_issue", "owner_id","tbl_user", "id", "CASCADE", "RESTRICT");
//the tbl_issue.requester_id is a reference to tbl_user.id
$this->addForeignKey("fk_issue_requester", "tbl_issue","requester_id", "tbl_user", "id", "CASCADE", "RESTRICT");
//the tbl_project_user_assignment.project_id is a reference to tbl_project.id
$this->addForeignKey("fk_project_user", "tbl_project_user_assignment", "project_id", "tbl_project", "id", "CASCADE","RESTRICT");
//the tbl_project_user_assignment.user_id is a reference to tbl_user.id
$this->addForeignKey("fk_user_project", "tbl_project_user_assignment", "user_id", "tbl_user", "id", "CASCADE", "RESTRICT");
}
catch(Exception $e)
{
echo "Exception: ".$e->getMessage()."\n";
}
}
public function safeDown()
{
$this->truncateTable('tbl_project_user_assignment');
$this->truncateTable('tbl_issue');
$this->truncateTable('tbl_user');
$this->dropTable('tbl_project_user_assignment');
$this->dropTable('tbl_issue');
$this->dropTable('tbl_user');
}
}
This is not working when i run the migrate command from the shell .Migrate command is working perfectly for other pages .Note that this code is in safeUp method. if i put the code in the up() method it works fine… i am not getting any error in the console .Just a success message. I partially commented the codes and found that nothing is working inside the safeUp method. Can you tell me what is wrong. Actually i have copy pasted the code given in the book.
