Argument Error?

View layer:

<%= thumbnail_tag (@content_page.picture1), :border => 0, :width =>
489,
:height => 236 %>

Helper layer:

def thumbnail_tag(picture, options = {})
  link_to(scale_image_tag(picture, options.merge({:border => 0})),
"/settings/view_image/#{picture.id}", :popup =>
["_blank",
"width=#{picture.width+15},height=#{picture.height + 10}"])
 end

Can someone help me diagnose this problem?

What method is it saying has too many arguments? The call to
''thumbnail_tag'' or to ''scale_image_tag'' or
to ''link_to''?

Really? Strange.
What happens if you try to call thumbnail_tag with no arguments?

Can you post a few extra lines from the error messages you get in both
cases; I''m curious if they''re *exactly* the same...

Re: Re: Re: Re: Argument Error?

To add to that, here is the scale_image_tag helper method:

def scale_image_tag(picture, options = {})
  if picture
#    raise options.to_yaml
    image_tag(picture.url(options[:width], options[:height]), 
options.merge({:alt => picture.image_alt, :title => picture.image_alt}))
  else
    image_tag("clear.gif", options)
  end
end

Pastebin! Save the list''s bandwith and our eyes! ;-)

Anyway; they''re both complaining about
''scale_image_tag''...
    app/helpers/application_helper.rb:44:in `scale_image_tag''

I''d stick some breakpoints on there, and see what''s happening.

Do you fancy letting the list know what the solution was? ... it may
help someone else in future.

Erroneous:

  def scale_image_tag(picture, options = {})
    if picture
      #raise options.to_yaml
      image_tag(picture.url(options[:width], options[:height]), 
options.merge({:alt => picture.image_alt, :title => picture.image_alt}))
    else
      image_tag("clear.gif", options)
    end
  end

  def thumbnail_tag(picture, options = {})
    link_to(scale_image_tag(picture, options.merge({:border => 0})), 
"/settings/view_image/#{picture.id}", :popup =>
["_blank",
"width=#{picture.width+15},height=#{picture.height + 10}"])
  end

Working:

  def scale_image_tag(picture, options = {})
    if picture
      image_tag(Picture.image_url(picture.resize(options[:width], 
options[:height])), options.merge({:alt => picture.image_alt, :title => 
picture.image_alt}))
    else
      image_tag("clear.gif", options)
    end
  end

  def thumbnail_tag(picture, options = {})
    link_to(scale_image_tag(picture, options.merge({:border => 0})), 
{:controller => ''settings'', :action =>
''view_image'', :id => picture},
:popup => ["_blank",
"width=#{picture.width+15},height=#{picture.height
+ 10}"])
  end

Off topic, but...no!  Don''t make me go elsewhere to see the code under 
discussion!  Keep code discussed here on the list.
