How to run view helpers from rails console?

[Wins Lin]

With
> rails console --sandbox
I cant test my models, save data to db and all will be rolled back
after.

But is it possible to test view helpers from console? I talk about these
helpers:
> post_path
> link_to
> url_for
> edit_post_path
> new_post_path

When I call them, I get an error:
irb(main):003:0> post_path(:post)
NameError: undefined local variable or method `post_path' for
main:Object

Is there a way to call those methods from Rails console? Through which
object do I need to call them?

The routing helpers are all defined on Rails.application.routes.url_helpers

The other helpers are defined on the helper object

 helper.number_with_precision(1.1235)

This doesn't always work - some of the helpers rely on their being a controller/request around and these won't be able to run.

i think you can also use app for the url_helpers

app.posts_path for example

Oh, yes, this works, they both work. Thank you, that's what I was
looking for.

irb(main):005:0> app.posts_path
=> "/posts"
irb(main):006:0> Rails.application.routes.url_helpers
=> #<Module:0x2d854b8>
irb(main):007:0> Rails.application.routes.url_helpers.posts_path
=> "/posts"
