There are a few ways to do this. Like @meager, you want to call Post.new. I usually do it in the controller, though.

posts_controller.rb

@post = Post.new

view

 <% form_for @post do |f| %>
   ...
 <% end %>

You can use a custom path if that's where you want to send the data. So if you have a special case, you can make a route for it

routes.rb

get '/special', to: 'posts#special'

then you can have a form that says...

<% form_tag special_path do |f| %>
   ...
<% end %>

and the params will pass as you'd think. Notice the form_tag instead of form_for though.

form_for expects an instance of a model, not a symbol:

<% form_for Post.new do |f| %>
...
<% end %>
