Ruby on rails link_to syntax
After following a tutorial Ive found. Im now redoing it again, without the scaffolding part, to learn it better.
However, editing my \app\views\home\index.html.erb to contain:
<h1>Rails test project</h1>
<%= link_to "my blog", posts_path>
I get an error:
undefined local variable or method `posts_path' for #<ActionView::Base:0x4e1d954>
Before I did this, I ran rake db:create, defined a migration class and ran rake db:migrate, everything without a problem.
So the database should contain a posts table. But that link_to command cant seem to find posts_path. That variable (or is it even a function?) is probably defined through the scaffold routine.
My question now is; how do I do that manually myself, define posts_path?
Answer
You will need to define a path to your posts in config/routes.rb
Rails 2.x syntax:
map.resources :posts
Rails 3.x syntax:
resources :posts
