The problem variable here is @item_class. It's not passing as an extra

I have in my partial

<%= %> #Just to make sure @item_class is not null
<%= link_to_if someCondition, 'myLink', :action=>:myLinkAction, :id =>
@item,:item_class=> %>

the above renders

<a href="/item/myLinkAction/10">myLink</a>

which is missing the extra parameter Photo.

Why don't I see

<a href="/item/myLinkAction/10?item_class=Photo">myLink</a>

if I add a string like 'wibble'
<%= link_to_if someCondition, 'myLink', :action=>:myLinkAction, :id =>
@item,:item_class=>, :extra=>'wibble' %>

I get

<a href="/item/myLinkAction/10?extra=wibble">myLink</a>

if you enter :item_class=> 'wibble' what do you get?

Ok, if I switch it to

<%= %>
<%= link_to_if someCondition, 'myLink', :action=>:myLinkAction, :id =>
@item,:extras=>, :item_class=>'wibble' %>

I get

<a href="/item/myLinkAction/10?extras=Photo">myLink</a>

What's the problem with using a parameter having a same name as a
variable? I didn't see this issue until I went to 1.2.2 from 1.1.6.

I REALLY appreciate the help, it's been about 2 weeks I've been
wrestling with this.

Yeah, seems the link_to_if helper thinks your trying to assign a value
to the :item_class symbol which already exists, not pass it a param.

Have you thought about renaming your param?

You could override the link_to_if helper and see what it's spitting out:

def link_to_if(condition, name, options = {}, html_options = {},
*parameters_for_method_reference, &block)
return *parameters_for_method_reference

no clue if that'll work though....

good luck.

One other note, this only happens with named routes. item_class is
assigned in the named route, I get the results above.  If I manually
type it into the url, it's fine.

I'll try your suggestion. Thanks again for the help.

Ok if I return the various arguments passed in, I see:

condition: true
name: myLink
html_options: NULL
*parameters_for_method_reference: NULL

No block supplied, so didn't check that.

What were you expecting for *parameters for method_reference?

parameters_for_method_reference should probably be nil.

What is the route for this action?  What does
url_for(:action=>:myLinkAction, :id =>
> @item, :extras=>, :item_class=>'wibble') generate?

The url_for generates:
