Insert error when sending post array to activerecord

Question

I am using CodeIgniter + phpActiveRecord. I am getting all the records from the $_POST array and I want to send that same array to my activeRecord class to insert the data into the DB.

This line doesn't seem to be working but I can't get the error because the page is just blank:

Car::create($this->input->post());

If the names of the fields are equal to the names of the columns in the table, should it what I pasted above work?

==========SOLVED========

It is possible to do it, and in the model of the object one can add var $name_of_the_field_which_you_don't_process = FALSE;

And that's it.
