以下是错误消息：

And there is the ligne in my project/settings.py
TEMPLATE_DIRS = (
"/home/sarfraz/django/crepes_bretonnes/templates/"
)
希望很清楚。
答案 0 :(得分：1)
在括号之间关闭的值的末尾添加逗号，否则它不是<?php
$dataArray=array();
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "SELECT reg_date,xyz,pqr FROM stuvw";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
// output data of each row
$test = mysqli_num_rows($result);
echo $test;
while($row = mysqli_fetch_assoc($result))
{
$populate = '"' . $row["reg_date"]. '"'."=>" . $row["xyz"]. ", " ;
$dataArray[$populate] = $test;
}
echo $dataArray[$populate];
}
mysqli_close($conn);
?>
：
tuple
它应该解决问题。希望它有所帮助。
