Subject: [ruby-core:90491] [Ruby trunk Bug#15409] OpenStruct error when attribute is called 'method'
Date: Thu, 13 Dec 2018 05:46:54 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-75649.20181213054652.cb2751467559d18d@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-15409.20181213032526@ruby-lang.org
Issue #15409 has been updated by oleynikov (Alexander Oleynikov).
According to the docs, `OpenStruct` uses `method_missing`, so it does not redefine existing methods of `Object` or `BasicObject`.
https://docs.ruby-lang.org/en/trunk/OpenStruct.html
```ruby
o = OpenStruct.new(
method: 'method',
class: 'class',
display: 'display',
send: 'send',
__id__: '__id__',
frozen?: 'frozen?'
)
o.method #=> ArgumentError (wrong number of arguments (given 0, expected 1))
o.class #=> OpenStruct
o.display #=> #<OpenStruct method="method", class="class", display="display"...
o.send #=> ArgumentError (no method name given)
o.__id__ #=> 7539827944720
o.frozen? #=> false
```
----------------------------------------
Bug #15409: OpenStruct error when attribute is called 'method'
https://bugs.ruby-lang.org/issues/15409#change-75649
* Author: elioncho (Elías Orozco)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin16]
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
The following error is shown when you try to access an OpenStruct with a property called method:
`method': wrong number of arguments (given 0, expected 1) (ArgumentError)
To replicate:
~~~ ruby
require 'ostruct'
o = OpenStruct.new({ method: 'get' })
o.method
~~~
The expected behavior should be to return 'get'
