Well right now i’m currently trying to make a form that posts  
information into my database. I’m using the form\_for function, but  
when i run the server and go to the page and get this error:

undefined method `posts\_path’ for #ActionView::Base:0x23bbabc

So i have no idea what i’m doing wrong, here is the code for the form:

\<% form\_for(@posts) do |p| %\>  
\<%= p.error\_message %\>

\<%= p.label :title %\>  
 \<%= p.text\_field :title %\>

\<%= p.label :post %\>  
 \<%= p.text\_area :post %\>

\<%= p.submit "Submit Post" %\>

\<% end %\>

Any idea?

You have no route for posts declared.

You can only use named routes (which form\_for uses when you pass it an  
AR object) if you declare them. This is done with the map.resource and  
map.resources methods in your config/routes.rb file. Read up on named  
routes.

submit the information into the server.
