+``` + +### Instance Variables in Views + +In general, passing data between templates with instance variables is discouraged. This even applies from controllers to templates, not just between partials. + +`:locals` can be used to pass data from a controller just like partials. + +``` ruby +def show + render "blob/show", locals: { + :repository => current_repository, + :commit => current_commit, + :blob => current_blob + } +end +``` + +Rails implicit renders are also discouraged. + +Always explicitly render templates with a full directory path. This makes template callers easier to trace. You can find all the callers of `"app/view/site/hompage.html.erb"` with a simple project search for `"site/homepage"`. + +``` ruby +def homepage + render "site/homepage" +end +``` + +#### Exceptions + +There are some known edge cases where you might be forced to use instance variables. In these cases, its okay to do so. + +##### Legacy templates + +If you need to call a subview that expects an instance variable be set. If possible consider refactoring the subview to accept a local instead. + +##### Layouts + +Unfortunately the only way to get data into a layout template is with instance variables. You can't explicitly pass locals to them. + [rubocop-guide]: https://github.com/rubocop-hq/ruby-style-guide diff --git a/config/default.yml b/config/default.yml index 52a0655e..0a3672c7 100644 --- a/config/default.yml +++ b/config/default.yml @@ -1,3 +1,6 @@ +inherit_from: + - ./default_pending.yml + require: - rubocop-github - rubocop-performance @@ -65,8 +68,10 @@ Layout/BlockAlignment: Layout/BlockEndNewline: Enabled: true +# TODO: Enable this since it's in the styleguide.
