The create() method takes in a hash containing keys names the same as fields in the respresentative table. In this case, you’ll probably be passing in:
params = { :post => { :id => [postid] }, { :comment => { :body => ‘some body text’ } }
Thus, you can just modify the poster form to include a comment_poster_id field which will automatically be added into the hash for you.
However if you need to add such values in the Controller, you can do this:
def add_comment comm = Comment.new(params[:comment]) comm.poster_id = poster_id comm.commented_time = Date.today # or whatever
Post.find(params[:id]).comments << comm # I think this saves for you but I can’t remember.
end
There are many different ways of manipulating ActiveRecord objects. If in doubt, just seperate out into seperate objects and do what you need.
Hope that helps.
