Try specifying the model and url separately: form_with(model: @activity, url: [@trip, @activity]) According the docs the the values for url are “Akin to values passed to url_for or link_to” so using an array should work. This also works with shallow nesting since the array is compacted.
I had a similar problem. The solution was to add the file extension on the image. = image_tag ‘logo’, alt: ” to = image_tag ‘logo.jpg’, alt: ”
Try using before_action :zero_authors_or_authenticated, only: [:new, :create] Instead of before_filter :zero_authors_or_authenticated, only: [:new, :create] before_filter has been deprecated in Rails 5.0 and removed in 5.1.
I just faced exactly the same problem. I sovled it by setting: config/environments/development.rb from: # Do not eager load code on boot. config.eager_load = true to: **# Do not eager load code on boot. config.eager_load = false Hope this helps! Cheers, Nic.
