File_column

Rails
1

i have an array of entries and i want to show all images on screen

i try with

<%for entry in @entries%>
<%= image_tag url_for_file_column(“entry”, “image”)%>
<%end%>

i got nil object

what i am doing wrong here?

file_column looks for the var @entry with the @ otherwise it will return
nil

you need something like

<% for object in @entries %>
<% @entry = object %>
<%= image_tag url_for_file_column(“entry”, “image”)%>
<%end%>
