+++ title = "Deprecation: Resource Property Name Collision (CHEF-11)" draft = false
gh_repo = "chef-web-docs" robots = "noindex" sitemapExclude = true aliases = "/deprecations_property_name_collision.html" +++
A resource property, defined with the property method, conflicts with
an already-existing property or method. This could indicate an error
that could lead to unintended behavior.
All Ruby objects have a number of methods that are expected to always be available. When a resource property is created, Ruby methods for setting and getting the property value are created for you. If a resource creates a property which is named the same as an existing method, the original method will be overwritten.
For example, every Ruby object has a hash method which is expected to
return a number. If a resource creates a property named hash and
stores a string instead, it could cause errors in your Chef run.
A deprecation warning is logged when this occurs. In Chef Infra Client 13, this will raise an exception and your Chef run will fail.
Modify the resource and choose a different name for the property that does not conflict with an already-existing method name.
