Why doesn't `posts_path` work in `rails console`?

Question

Why does link_to 'Back', posts_path work in ERB but posts_path doesn't work in the console?

$ rails console
irb(main):005:0> posts_path
NameError: undefined local variable or method `posts_path' for main:Object

Answer 1

You need to add context of app in console.

app.posts_path
app.get app.posts_path
app.response
app.response.body
