我在数据库中有一个名为marital_status的表。它只包含两列user_id(类型为Integer),另一列名为is_married(类型为boolean)。
因此,当我通过雄辩模型检索用户的婚姻状况时,我会除了布尔值。
public class register extends AppCompatActivity {
EditText username, password;
Button registartion;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
}
private Connection getConnection()
{
String host = "jdbc:mysql://jdbc.fmc.me.uk:3306/db_ben";
String u = "user_ben";
String p = "******";
try
{
Connection con = DriverManager.getConnection(host, u, p);
return con;
} catch (SQLException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
private boolean registerUser(){
//Get username
EditText regUsernameBox = (EditText) findViewById(R.id.RegUsername);
String regUsernameStr = regUsernameBox.getText().toString();
//Get password
EditText regPasswordBox = (EditText) findViewById(R.id.RegPassword);
String regPasswordStr = regPasswordBox.getText().toString();
System.out.println(regUsernameStr);
System.out.println(regPasswordStr);
int i = 0;
Connection con = getConnection();
try {
PreparedStatement pst = con.prepareStatement("insert into users values(?,?)");
pst.setString(1, regUsernameStr);
pst.setString(2,regPasswordStr);
i = pst.executeUpdate();
} catch (SQLException e) {
e.printStackTrace();
}
if(i>0)
return true;
return false;
}
public void buttonClick() {
final Button registerUsers = (Button) findViewById(R.id.bRegister);
registerUsers.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
registerUser();
}
});
}
}
结果是正确的,但我没有使用布尔字符串' 0'或者' 1'。有人可以解释一下吗?
答案 0 :(得分:1)
您可以在模型中解决此问题:
protected $casts = [
'is_married' => 'boolean'
];
