How to display all posts in a blog application using Rails 3?

I am trying to implement a blog application in my app.But i am getting the following error after saving the posts.

Error:

NoMethodError in Homes#blog

Showing C:/Site/library_management1/app/views/homes/blog.html.erb where line #19 raised:

undefined method `name' for #<Array:0x21896a0>

Actually My blog implementation story is like this.When a logged in user will add his name and comment in required place and clicked on submit button all blogs will saved as well as display.All comments should visible to all logged in users belongs to this app.Suppose one user wants to reply/edit then he/she can do this.
