ruby - Rails App - Object_ID Returning for User Name -


i developing simple blog app , having trouble displaying user name associated comment.

comments belongs_to :posts , :users. posts belongs_to :user , has_many :comments. users has_many :posts , :comments.

the create action in comments model works , stores comments expected post_id , user_id:

class commentscontroller < applicationcontroller  def create   @post = post.find(params[:post_id])   @comment = @post.comments.create(comment_params)   @comment.user = current_user   if @comment.save     redirect_to @post   else     flash.now[:danger] = "error"   end end  private    def comment_params     params.require(:comment).permit(:content)   end  end

i able access user name via console expected comment.first.user.name returns users name. when trying in view, following error:

undefined method `name' nil:nilclass

here view: 

<% @post.comments.each |comment| %>   <p>user:<%= comment.user.name %></p>   <p>comment:<%= comment.content %></p> <% end %>

when remove .name user in view, app displays looks object_id. 

user:#<user:0x00000001f62830> comment:test comment

i've tried resetting database mentioned here: show username when posting comments in rails

i've tried address proxy_id mentioned here: returning issue in comment::activerecord_associations_collection

i'm not sure else try. also, when reset comments table there no data in it, app still displays:

user:   comment:

when loops through though there no data in it. think has dynamic finder confused id, tried moving controller mentioned here, retrieving username find_by_id(comment.user_id).name not working, , still getting undefined method errors. ideas? appreciate insight. not using comments gem, developing in cloud9, , using postgresql.

i found issue in post: using <%= render comments %> outputs empty partial, if there nothing in database

"the issue form above <%= render @post.comments %> there empty comment when reach partial comments, if there's none in database, put <%= render "comments/form" %> below fix this."

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
