Constant Summary collapse
- MSG =
'This method can only be used inside an ActiveRecord model: ' \ 'https://gitlab.com/gitlab-org/gitlab-foss/issues/49653'
- NOT_ALLOWED =
Various methods from ActiveRecord::Querying that are denied. We exclude some generic ones such as ‘any?` and `first`, as these may lead to too many false positives, since `Array` also supports these methods.
The keys of this Hash are the denied method names. The values are booleans that indicate if the method should only be denied if any arguments are provided.
