Stylesheet_link_tag

Rails
1

Hi,

I have the following, very simple, simple layout -

<%= title_tag %> <%= stylesheet_link_tag %>

Main Title

Up until this point, the HTML's coming from the application layout.

<%= @content_for_layout %>

which renders fine but without a stylesheet tag in the HTML. If I
change the stylesheet tag to -
<%= stylesheet_link_tag “main”, “blog”, :media => “all” %> or even
<%= stylesheet_link_tag “main” %>

  • then I get an exception raised -

wrong number of arguments (2 for 0)

I have a number of options for working around this, but I’d like to
understand where I’m going wrong. Anyone care to enlighten me? TIA.

hey man,

I just pulled this from my working template:
<%= stylesheet_link_tag ‘style’ %>

the only difference I can see is you used double quotes, I’m on
singles, see if that helps. I guess its not rendering a style tag
because you haven’t passed it any parameters like name etc…

Im still learning myself so I may be wrong, but you never know!

cheers,
Lee

Nope, still getting the exception. I’ve got a stack trace which points
me at the method which is throwing the exception. I guess I’m going to
have to dig around in the code and see if I can work it out.

Do you get the same exception when <%= title_tag %> is removed?

I see where you’re going with this. Is it my dodgy helper method? :).
Unfortunately not, I get the same error.

Hi,

That’s REALLY odd.

What happens if you have nothing but the stylesheet link tag in your
layout?

stylesheet_link_tag with no parameters appears to be an error according
to the comments in the helper method that handles this tag. Your last
option should work, though (with just “main” as a parameter). You do
have a css file called “main.css” in your public/stylesheets directory,
right?

You could also try:
<%= stylesheet_link_tag :all %>

…which is supposed to make style link tags for all the .css files in
your stylesheets directory.

Yep, there’s a main.css in public/stylesheets.

I just tried it with :all. Got the same exception.

Ah, cracked it. I had a helper method named stylesheet_tag in
application_helper.rb. This was clashing with the identically named
method in action_view/helpers/asset_tag_helper.rb.

If I have a layout with only this -

<%= stylesheet_tag %>

, then I get this rendered -

OTOH, if I have a layout with only this line -

<%= stylesheet_tag ‘main’ %>,

then I get a “wrong number of arguments” exception.
