Duplicated Code
Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).
Tuning
This issue has a mass of 69.
We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.
The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.
If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.
See codeclimate-duplication
's documentation for more information about tuning the mass threshold in your .codeclimate.yml

This cop checks for redundant uses of self
.
self
is only needed when:
-
Sending a message to same object with zero arguments in presence of a method name clash with an argument or a local variable.
Note, with using explicit self you can only send messages with public or protected scope, you cannot send private messages this way.
Example:
def bar :baz end
def foo(bar) self.bar # resolves name clash with argument end
def foo2 bar = 1 self.bar # resolves name clash with local variable end
-
Calling an attribute writer to prevent an local variable assignment
attr_writer :bar
def foo self.bar= 1 # Make sure above attr writer is called end
Special cases:
We allow uses of self
with operators because it would be awkward
otherwise.
