TypeError: Effect[effect_class] when using block form of link_to helper

Rails
1

Anyone have any idea why I’m getting this error when using the block
form of the link_to helper in Rails 2.0.1? I’m essentially using the
exact same code as in the Rails doc example, but no luck. Any help
would be appreciated.

2

Sorry, meant link_to_function, not link_to.

Could you show us the exact code you’re using please?

Ryan,

I’m using the following code in my .rhtml file:

<%=
link_to_function(“show”, nil, :id => “more_link”, :class =>
“expand_collapse”) do |page|
page[:user_listings].visual_effect :toggle_appear
page[:more_link].replace_html “hide”
end
%>

5

I should have mentioned that ‘user_listings’ is the id of a div
defined on my page.

I was not aware you could use link_to_function as a block.

It has something to do with your :toggle_appear custom function at a
guess.

link_to_function(“show”, nil, { :id => “more_link”, :class =>
“expand_collapse” } )

It’s in the Rails docs here:
ActionView::Helpers::JavaScriptHelper.
Specifically, this part:

“The function argument can be omitted in favor of an update_page
block, which evaluates to a string when the template is rendered
(instead of making an Ajax request first).”

Followed by an example similar to the one I posted.

  • It has something to do with your :toggle_appear custom function at a
    guess.

AFAIK, there is no toggle_appear visual effect. It’s either toggle, or
appear. Not both.
