How to run view helpers from rails console?

Rails
1

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?

Test them from tests.

url_for

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”
