Hiii K Arunmohan,
Now Add form is working by changing..
@content_master.tags=params[:content_master][:tag_ids]
@content_master.tag_ids=params[:content_master][:tag_ids]
tags to tag_ids
but in edit form there is one problem..
when there is last entry which is selected and i want to unassign it , it
dont do..
why it is not doing..
in update method m having this simple code
def update
@content_master = ContentMaster.find(params[:id])
respond_to do |format|
if @content_master.update_attributes(params[:content_master])
i tried this below this
@content_master.tags.delete_all(params[:content_master]
[:tag_ids]).each{|i|@content_master.tags << Tag.find(i)}
but it is giving error of wrong number of argument..
please help..
thanks
rahul
