Ruby on Rails偏爱控制器和语法问题

Question

I'm creating a "destroy" method in my favorites_controller. Not sure how I should express the commented-out requirement below, asking to find the current user's favorite with the ID in the params. I know I'm close but my current knowledge of ruby syntax is not up to par yet. An "undefined method `favorite' for #" error pops up and points to the [initialized?] 'favorite' variable line below when I use the unfavorite function of my app. Please help. Thank you!

def destroy
    # Get the post from the params
    @post = Post.find(params[:post_id])
    # Find the current user's favorite with the ID in the params
    favorite = current_user.favorite.find(params[:id]) 
    if favorite.destroy
      flash[:notice] = "Post was succesfully un-favorited"
      redirect_to @post 
      # Flash success and redirect to @post
    else
      flash[:error] = "There was an error in un-favoriting this post"
      redirect_to @post
      # Flash error and redirect to @post
    end
  end

Answer 1

I'm assuming the User can have many Favorites, since you're attempting to single one out via params[:id] . If that's the case, try changing .favorite to .favorites .

Hope that solves it!

我猜用户和收藏夹之间的关系是has_many，因此在这种情况下，您应该使用current_user.favorites
