Hi,
I have a set of image tags which I use frequently in my views, so I want
to gather these tags for reuse, something like:
module ApplicationHelper
ICON = { :email => image_tag(''/images/icons/email.gif'',
{''title'' =>
''Send Email''}),
:arrow_up =>
image_tag(''/images/icons/arrowup.gif''),
:arrow_down =>
image_tag(''/images/icons/arrowup.gif'')
}
End
Then in a view, I would replace:
<%= image_tag ''/images/icons/email.gif'',
{''title'' => ''Send Email''} %>
With the simpler:
<%= ICON[:email] %>
But when I try this, I get an error - NoMethodError (undefined method
`image_tag'' for ApplicationHelper:Module)
So two questions:
1) whats the best way to make tag helpers available to the helper ?
2) is there a better way to gather by my ''static'' view assets
and so DRY
Thanks,
Nev

You could do: def icon(which) case which when :email image_tag(''/images/icons/email.gif'', {''title'' => ''Send Email''}) when :arrow_up image_tag(''/images/icons/arrowup.gif'') when :arrow_down image_tag(''/images/icons/arrowup.gif'') end end - Jamis
