Hello Experts,

I am fetching data in my controller from a web service

def search  
response = @@api.DoSearch()  
end

and in my .rjs template, I am doing

page.replace\_html ‘fields\_chooser’, :partial =\> ‘fields\_chooser’  
,:locals =\>{:response =\> response}  
page.visual\_effect(:Appear, ‘fields\_chooser’)

and in \_fields\_chooser.rhtml, I want to use response. But I can’t see  
response in my .rhtml file.

what am I missing here? how do I pass data “response” from controller to  
the .rhtml file or should I be doing this in a different way?

Thanks guys for any help.

PS

Did you mean @response instead of “response”?

Hi,

I am actually using response.

strangely, If I do @response = @@api.DoSearch()

I get this error:

undefined method `body=’ for #Array:0x36accd0

Stack trace below:

however, if I just use response, I can see the response fine in logger,  
but I am not able to pass the response to the rjs template.

I am a NewB, so apologize if am not very clear.

Your help is greatly appreciated.

thanks,

I haven’t been able to get the :locals parameter to work in an RJS call  
either, so what I’ve done in cases like this is to use an instance  
variable. @response is a reserved attribute so you might try a  
different variable name in such a case.

The response variable that you have set

response = @@api.DoSearch()

is only local scope. When you enter your rjs, it has gone out of scope.

Use  
@response = @@api.DoSearch()

and in the rjs  
page.replace\_html ‘fields\_chooser’, :partial =\> ‘fields\_chooser’  
,:locals =\>{:response =\> @response}  
page.visual\_effect(:Appear, ‘fields\_chooser’)

I think this should fix it.
