newbee question:

I have a form, where I want to add a choice of weekdays a movie is  
playing into one field:

\<%= select\_tag ‘days[]’, options\_for\_select([[“monday”, “2”],  
[“tuesday”, “3”], [“wednesday”, “4”], [“thursday”, “5”], [“friday”,  
“6”], [“saturday”, “7”], [“sunday”, “1”]]),:multiple =\> true %\>

how can I save days.join(",") into @movie.weekdays when I create a new  
movie record?

def create  
@movie = Movie.new(params[:movie])  
respond\_to do |format|  
if @movie.save  
flash[:notice] = ‘Movie was successfully created.’  
format.html { redirect\_to(movies\_path) }  
else  
format.html { render :action =\> “new” }  
end  
end  
end

I’d use merge right about here:

params[:movie].merge( :days =\> days.join(‘,’) )
