I am trying to set my app up so on the user page, if they don't have any images, then it shows text saying that they don't. It will also show a link to upload new images.
I have tried this but it shows undefined method 'image?' for #<WillPaginate::Collection:0x007f93a1e0e638>
undefined method 'image?' for #<WillPaginate::Collection:0x007f93a1e0e638>
- if @images.image?
- @images.each do |image|
= image_tag ("devices/#{image.device}.png"), :class => "img_#{image.device}"
- if image.image?
= link_to image_tag(image.image_url(:small), :class => "explore_#{image.device}"), image
- else
= image_tag '123-small.jpg', :class => "explore_#{image.device}"
- else
%p Looks like you don't have any images uploaded!
Edit: images_controller.rb
def index
@title = "My Images"
@images = current_user.images.paginate(:page => params[:page])
end
It looks like you're trying to test whether there are any images in @images
, and just using the wrong method for that. Instead try:
- if @images.present?
According to your code, @images
is obviously a WillPaginate::Collection
of image
, which acts like an array.
Therefore, to test whether @images
is not empty , you should use if @images.present?
or unless @images.empty?
instead.
