Undefined variable in view template
ActionView::Template::Error.*undefined local variable or method
Fixes
- 1.Pass the variable from controller: @variable in action
- 2.Use local_assigns.key?(:var) for partials with optional locals
- 3.Check the render call passes required locals: render partial: 'x', locals: {var: val}
