Hello I am new in nette and I was creating my first application and I get this error

Nette\MemberAccessException
Cannot read an undeclared column "created_at"

please anyone can help me out of this?

Can you dump the object? Just add {dump $post} to the template and look at “Variables” in debug bar. Is there created_at column in data?

Filip Procházka

Are you sure you have it in the database table?

You should probably create a screenshot, this is not very synoptical. And also try deleting the cache.

Thank you Filip It's already working the problem was in the name of the row in the table it was misspelled.
