I want to pass 2 variables (@variableA, @variableB) to my controller  
“search” when the following href is clicked:

myView.rhtml:

- **HOTEL**

I need the 2 variables for my condition string, which should work  
something like this:

conditions = [“hotel\_id = ? AND city\_id = ?”, @variableA, @variableB]  
unless @hotel\_id.nil?

Are you hard coding the link like that? Because you are using a help you  
could say:

\<%= link\_to ‘Home’, { :action =\> ‘home\_form’, :id =\> ‘arg\_1’, :id2 =\>  
‘arg\_2’ } %\>

yes, it’s hard coded because of my quite extensive stylesheet (a, b, ul,  
li…)

Thank you guys,

this looks ugly but it works now:

**HOTEL**

a better solution:

\<%= link\_to\_remote “ **HOME** ”, { :url =\> { :controller =\> “search”,  
:action =\> “index”, :arg1 =\> “1”, :arg2 =\> “2” }, :update =\>  
“resultsTable”, :success =\> “Element.hide(‘spinner’)” } %\>

link\_to\_remote “ **HOME** ” is certainly not perfect, but I can live  
with this 🙂

Zoran,

Since you’re hard-coding all of this, an even better solution would be  
to use a named route. You add named routes in the config/routes.rb  
file. Search for ‘named route’ and it’ll give you an example (around  
line 10 of a vanilla routes.rb).

In your case you’d probably add something like this:

map.connect  
‘home’, :controller=\>‘search’, :action=\>‘index’, :arg1=\>1, :arg2=\>

Then your method call is reduced to:

link\_to\_remote “**Home\</  
b\>”, :url=\>home\_url, :update=\>‘resultsTable’,  
:sucess=\>'Element.hide(‘spinner’)**

 

As an observation, you might want to also change :success  
to :complete. That way the spinner gets hidden even with an error  
response (success only triggers with a 200 response).
