Basically, Im trying to add comments to photos that other users have
uploaded. And Ive encountered an error:
NoMethodError in CommentsController#create
undefined method `user_id=’ for #Comment:0x4768cd0

This is my comments controller:
class CommentsController < ApplicationController
before_filter :login_required
def create
@photo = Photo.find_by_user_id_and_id(params[:user_id],
params[:photo_id])
@comment = Comment.new(:user_id => @logged_in_user.id,
:body =>
params[:comment][:body])
if @photo.comments << @comment
flash[:notice] = ‘Comment was successfully created.’
redirect_to photos_path(:user_id => @photo.user,
:photo_id => @photo)
else
render :controller => ‘photos’, :action => ‘show’,
:user_id => @photo.user, :photo_id => @photo
end
end
def destroy
@photo = Photo.find_by_user_id_and_id(@logged_in_user.id,
params[:photo_id],
:include =>
:user)
@comment = @photo.comments.find(params[:id])
@comment.destroy
redirect_to entry_path(:user_id => @photo.user.id,
:id => @photo.id)
end
end
It said that the user_id is undefined when creating a new comment. Any
kind soul can tell me how to solve?
