Class Method Details

.enable? ⇒ Boolean

Returns true if we should enable tracking of query counts.

This is only enabled in production/staging if we're running on GitLab.com. This ensures we don't produce any errors that users can't do anything about themselves.

Returns:

  • (Boolean)

  Rails.env.development? || Rails.env.test?
end

.whitelist(issue_url) ⇒ Object

Allows the current request to execute any number of SQL queries.

This method should only be used when there's a corresponding issue to reduce the number of queries.

The issue URL is only meant to push developers into creating an issue instead of blindly whitelisting offending blocks of code.
