有没有办法使用鼠标滚动更改Twitter Bootstrap Carousel上的幻灯片？

问候

我有两个类DBConn和DBQueries.DBQueries继承之后DBConn.当我要在用户数据库中显示所有用户时,我看到消息:

mysql_fetch_array()期望参数1是资源,给定字符串.

class DBConn /*extends Config*/ {
  public function dbConnection(){
    $db_host = 'localhost';
    $db_login = 'root';
    $db_password = '';
    $db_name = "database";
    $conn = mysql_connect($db_host, $db_login, $db_password);
    $db = mysql_select_db($db_name);
  }  
}

class DBQueries extends DBConn {
  function displayUsers(){
    $this->dbConnection();
    $query = "SELECT * FROM users";
    $result = mysql_query($query);
    while ($row = mysql_fetch_array($query)) {
      echo $row['password'];
    }
  }
}

你好,我住在波兰,所以我必须处理像łóźć等字母.当我尝试添加,在管理pannel,文本像"ZespółSzkół"我得到这样的错误:

渲染时捕获UnicodeEncodeError:'ascii'编解码器不能编码位置4-5中的字符:序数不在范围内(128)

我在Stackoverflow页面上看到很多类似的问题,但我不知道如何解决我的问题.

我的数据库是MySQL

我的db的Unicode集合:utf8_unicode_ci

我的models.py

# -*- coding: utf-8 -*-
from django.db import models
import codecs

...    

class experience(models.Model):
    dateStart = models.DateField()
    dateEnd = models.DateField()
    company = models.CharField(max_length=50)
    position = models.CharField(max_length=50)
    description = models.TextField(max_length=255)
    def __unicode__(self):
        return self.company.decode('utf8')
