Is rails 4 find_by deprecated?
activerecord, ruby-on-rails, ruby-on-rails-4
Solution
According to the Rails 4 Release Notes:
All dynamic methods except for find_by_... and find_by_...! are deprecated.
`find_by` is not a dynamic method and therefore it's NOT DEPRECATED, and `find_by_...` & `find_by_...!` are dynamic, but still not deprecated as mentioned above.
So that means you still can use the original methods provided by Active Record without having to define your own:
Model.find_by_username(:username)
Model.find_by(username: 'value', age: 24)
If you want the functionality of the really deprecated finder methods you can either include the gem that they were moved into: activerecord-deprecated_finders. Or follow what the Rails 4 Release Notes say:
Here's how you can rewrite the code:
- find_all_by_... can be rewritten using where(...).
- find_last_by_... can be rewritten using where(...).last.
- scoped_by_... can be rewritten using where(...).
- find_or_initialize_by_... can be rewritten using find_or_initialize_by(...).
- find_or_create_by_... can be rewritten using find_or_create_by(...).
- find_or_create_by_...! can be rewritten using find_or_create_by!(...).
Problem
I heard that find_by is deprecated is this true? I have been thinking of alternatives such as creating for each `find` a different method, e.g.: before: ``` Model.find_by_username 'username' ``` after: --in model--- ``` class << self def by_username username where(:username => username).first end end ``` is it a good naming? what names do you give for such methods? Update: find_by is not deprecated but the announcement could have been clearer!
