Hi all,
In my application all users have the ability to upload a profile picture
through a file field but it is not compulsory.
On my index page it displays all users along with their profile pictures
but not all users have a profile picture and therefore some users have
no image at all.
How would I go about getting a generic image to display for the rest of
the users.
I have the following section in the index:
<% for user in @users %>
<tbody>
<td align = "center"><%= image_tag user.photo.url,
:height => 50,
:width => 50 %></td>
<td align = "center"><%= user.username %></td>
<td align = "center"><%= user.favourite_console
%></td>
<td align = "center"><%= user.games.count
%></td>
<td align = "center"><%= link_to "Show", user
%></body>
</tbody>
<% end %>
For the following line I want to do something like this:
If user has photo
<td align = "center"><%= image_tag user.photo.url,
:height =>
50, :width => 50 %></td>
else
display this photo
end
How would I go about doing this?
Thanks

This has the additional advantage that you can test it in the model unit test which is much easier than testing it in the view.

If you can put something in the model it is generally better than in a helper. But to use Walter''s method, did you change the code in the view to use the helper method?

I have had no luck :( I have got the following in my model def user_photo (photo.url.present?) ? photo.url : ''guest.png'' #tried with just photo.url end and the following my in index <%= image_tag user.user_photo, :height => 50, :width => 50 %> I don''t know what is stopping it from displaying the guest.png because if I changed the line to photo.url.blank? then it will display the guest.png for every user but with the present or simply photo.url line it just doesn''t display the guest.png for any of them.

My guess is that it will be something, but I don''t know what that is. Also, are you seeing any errors in the console when you test this locally?

In the console ''find'' a record with no url and then you can call your method and see what it returns, also you can call photo.url.present? and so on to see what they give.

That is coming from deep in the heart of Paperclip. You have two options. First, put your missing icon image at that path in your application. Second, choose a different method to test on your model. Instead of using the image accessor, look for one of the actual database columns in your model. (Look in db/schema.rb at your column names, pick something like photo_file_name or the local equivalent.) Then make the test in the method something to match: (user.photo_file_name?) ? photo.url : ''default.png'' The problem, as I should have picked up on from your earlier mention of the missing photo never appearing, is that photo.url always returns *something*, so it''s not a good test subject for the ternary operator.
