How to get the raw 'created_at' value in the database (not an object cast to an ActiveSupport::TimeWithZone)
Imagine I have a Post Model.
a开发者_运维知识库nd one record in the database will be:
23|title_here|content_here|2011-02-20 08:01:55.583222|2011-02-20 08:01:55.583222
and the last two field (2011-02-20 08:01:55.583222|2011-02-20 08:01:55.583222
) are the created_at and updated_at field.
Then,
post = Post.find_by_id(23)
Question: How can I get the created_at string: "2011-02-20 08:01:55.583222
" in the data base?
As we know, the post.created_at will return a ActiveSupport::TimeWithZone
object, not the raw string.
Please help :)
use attributes_before_type_cast
Post.find(23).attributes_before_type_cast["created_at"]
or
Post.find(23).read_attribute_before_type_cast("created_at")
Edit
You can call like this also:
Post.find(23).created_at_before_type_cast
according to Accessing attributes before they have been typecasted.
Try
Post.find_by_id(23).created_at.to_s
