Hi,

I am getting some error which I am clue less. I try to pass more than  
one parameter with redirect\_to, For example,

My params are…  
search =\> {“name”=\>"", “bus\_group”=\>“1”, “region”=\>"", “unapproved”=\>"",  
“tech\_owner”=\>""}

And I try to give.

redirect\_to params[:search].merge! (:action =\> ‘list’)

After executing this if I see in log file its showing like

{“bus\_group”=\>nil, “name”=\>"", “amp;region”=\>nil, “amp;tech\_owner”=\>nil,  
“region”=\>"", “amp”=\>"", “action”=\>“list”, “amp;name”=\>nil,  
“controller”=\>“tech\_projects”, “amp;unapproved”=\>nil, “unapproved”=\>"",  
“tech\_owner”=\>""}

I am confused why this “amp;” generally “&” will be parameter separator  
but one parameter itself called “amp;”.also every params are available  
twice.

I use something like this to pass extra params on restful routes.  
Notice the extra params inside the {}.

redirect\_to user\_path(@user, {:params1 =\> 1, :params2 =\> 2})

Hope it helps,

Thanks James,

But its not working, I am using redirect\_to in rjs.

If I use “update”, that RJS itself not working.

Try using:  
:escape =\> false

as an additinal Parameter.

Whenever you pass more than one parameter in an rjs using redirect\_to  
then it always adds & in the beginning of parameters after the  
first one. I had this issue as well in the past and after spending  
hours to fix it, I ended up using only redirect\_to instead of  
redirect\_to from rjs (basically I couldn’t sort it out).

My guess is that, & is added by prototype somehow.
