Yii Data add error

Yii Data add error
I used the GII to generate the article model
.....
Public Function Actioninsert () {
$ARTICLR _mode=new article ();
$ARTICLR _mode->article_title=$_post["title"];
$ARTICLR _mode->article_content=$_post["Content"];
$ARTICLR _mode->article_picture=$_post["Picname"];
$ARTICLR _mode->article_createtime=date (' y-m-d h:i:s ', Time ());
$ARTICLR _mode->article_state=1;
if ($articlr _mode->save ()) {
echo "Yes";
}else{
echo "No";
}
......
}
The page returned "No", no other error, not know where it was wrong.
Add error_reporting (E_all) to the page;
There are data in the $_post.
Here is my database table



------to solve the idea----------------------
Go to Yii website to see the operation of the database
