Question

I have the following:

:caption => thread.thread_widgets.first.widgetable.title

That works fine if the thread has a thread_widget, which is optional. Given it’s optional, if the thread has no thread_widgets, then this errors with

undefined method `widgetable' for nil:NilClass

Is there a way I can use try() so that the error doesn’t kill the page?

Thanks

Answer 1

:caption => (o = thread.thread_widgets.first) && o.widgetable.title

But you asked for Object#try, so:

:caption => thread.thread_widgets.first.try(:widgetable).try(:title)
