Fatal error: Cannot instantiate abstract class CActiveRecord in [PATH]\yii-1.1.8.r3324\framework\db\ar\CActiveRecord.php on line 371
This is a weird error, not sure how to consistently recreate it. I think it’s due to caching, I removed all schema caching and still get this at random with my Yii app.
Using Yii 1.1.8 also ran in to the issue with the latest from svn.
Any ideas?
What does line 371 contain?
Didn’t you forget to override CActiveRecord::model() in one of your model classes?
I didn’t, all of the models were generated by gii and had the static model function.
Can’t seem to get it to break anymore, guess I’ll never know… Weird!
I appreciate the help though 
As it was written on line 371, let’s try simply with:
// somewhere in code... totally random place
$model = new MyModel(); // try with parameter null also...idk <img src='http://www.yiiframework.com/forum/public/style_emoticons/default/smile.gif' class='bbc_emoticon' alt=':)' />
Second, in framework code right before line 371 add die(var_dump($className));
If there are no results, your AR class is definitely prefixed with abstract 
Hi i am new to yii,
Am creating a login form without using gii tool,
But thats generating an error <Cannot instantiate abstract class CActiveRecord">.I followed your step i.e to add die(var_dump($className));
and it displayed as <string(13) "CActiveRecord" >
so i want to know what actually is the error,Please help me as soon as possible and also give me the solution.
Thank you,
This is confusing, OP said that they used gii and got error. @nafisa now says WITHOUT gii. So is it with or without.
BTW @nafisa, the Login Form generated in the skeleton app doesn’t use gii either. It also doesn’t use ‘CActiveRecord’

Now its showing as <string(13) "CActiveRecord">
after including die(var_dump($className));
Please help me soon
Also, do not declare a class as abstract if you want to instantiate it.
I have not declared it as abstract in my class.
But then too am getting that error.
