this is my view:
<td align="left">
<% setupsheets_missing = true
@series800.setupsheets.each do |sheet|
setupsheets_missing = false
%>
<%=
link_to( image_tag(sheet.public_filename(:small), :border=>1, :style=>"margin-
right: 3p"),
'show_setup_sheet',:popup => ['sheet window',
'height=780,width=620']) %>
<%
end
if setupsheets_missing
%>
<%=
image_tag("/setupsheets/
missing_small.gif", :border=>1, :style=>"margin-right: 3px")%>
<%
end %>
</td><td></td><td></td></tr>
It works, but it is damned ugly.
if attachment_fu has saved multiple files, I get a list of thumb
picture links
if it has only saved on I get one thumb picture link
if it hasn't any I get a image_tag to a thumb bearing the word
"missing"
I would like to replace the abomination in the view code above with:
<td align="left"><%= sheet_links_for(@series800,:small) % ></td>
and a helper routine:
def sheet_links_for(series800,size = :small)
sheets_present = false
series800.setupsheets.each do |sheet|
sheets_present = true
link_to( image_tag(sheet.public_filename(size), :border=>1,:style=>"margin-
right: 3px"),
'show_setup_sheet',:popup => ['sheet window',
'height=780,width=620'])
end
unless sheets_present
image_tag("/setupsheets/
missing_small.gif", :border=>1,:style=>"margin-right: 3px")
end
end
But no... the 'missing tag' does show up, but the two links are
nowhere to be found.
I have been trying to spot the error for the past week... been over
this with a fine tooth comb, substituting image tags for the 2 links.
any ideas?
also is there a clean way to test for sheets present without
introducing a local variable.
Thanks in advance.
