Hi all…  
Can we render a partial file while clicking on a link?

I tried the following:

\<%= link\_to\_remote( “Cancel”,  
:update =\> “edit\_func\_spec\_div”,  
:url =\> {:partial =\>  
‘cipart/show\_functional\_spec\_to\_edit’}  
) %\>

But it didn’t rendered the partial file specified.

Also i need to pass a variable to this partial file. How can i do this?

Please help

Thanks in advance  
Regards  
Suneeta

You can do this, but not like that. The action you specify by the :url  
hash can render any partial you fancy.

Hi Fred…  
Thanks for your reply

I changed my code like this:  
\<%= link\_to\_remote( “Cancel”,  
:update =\> “edit\_func\_spec\_div”,  
:url =\> ‘cipart/show\_functional\_spec\_to\_edit’  
) %\>

But ‘no action found’ message generated.  
cipart is not an action. It is a folder that contains all partial files  
in my project.

So I changed the code as follows:  
\<%= link\_to\_remote( “Cancel”,  
:update =\> “edit\_func\_spec\_div”,  
:url =\> ‘/cipart/show\_functional\_spec\_to\_edit’  
) %\>

Then routing error generated.

Please help to solve this.

Thanks  
Suneeta

\<%= link\_to\_remote( “Cancel”,  
:update =\> “edit\_func\_spec\_div”,  
:url =\> {:controller =\> ‘mycontroller’, :action =\>  
‘myaction’, :myvar =\> 100 }) %\>

and then, in

Class MyController \< …  
…

def myaction  
myvar = params[:myvar]  
render :partial =\> ‘your/partial’, :locals =\> {:myvar =\> myvar }  
end

end

Hi…

Can’t we directly render a partial file in link\_to\_remote?

Thanks

No you can’t. link\_to\_remote generates javascript to make a request to  
your server. if you want that to render a partial then you need to  
have an action on the other side that renders that partial.

Hi…  
Is there any options other than link\_to\_remote for solving my problem?

if you didn’t want to use ajax, you could use javascript directly? You  
could render the form on the page, hide it, then show it when you  
click on your link. e.g:

 \<%= render :partial =\> "/cipart/show\_functional\_spec\_to\_edit" %\>

\<%= link\_to\_function “Cancel”, “$(‘my-hidden-form’).show()” %\>

However that depends on how complex your hidden section will be… it  
might not be appropriate.

Thanks Fred.  
I have to implement this function in many places. I was trying to avoid  
writing many actions for such a simple functionality.  
So now i’m planning to write a single action and combine all by checking  
conditions.  
Thanks again
