Rails get controller action url

Question

I have an action, and I've defined it in the routes.rb

resources :statistics, only: [] do
  get 'group_report/:id', to: 'statistics#group_report', as: 'group_report'
end

Then in the method in the model, I want to return the full URL.

Thus, I wrote this method

root_url + group_report_statistics_path(id)

The result is "http://localhost:3000//statistics/group_report/DHo6qzUzYXw"

I thought it was a dirty way, and I need to handle the double slash as well.

Does Rails provide some useful method which I can get the full URL of the action directly?

Answer 1

Use group_report_statistics_url(id)

_path helpers provide a site-root-relative path. You should probably use this most of the time.

_url helpers provide an absolute path, including protocol and server name. I've found that I mainly use these in emails when creating links to the app on the server. They should mainly be used when providing links for external use.

Answer 2

Rails provides path as well as url helpers for all the routes.

So if you use group_report_statistics_url(id) , you will get the full URL.

Answer 3

try this

File.join(root_url + group_report_statistics_path(id))

or

 group_report_statistics_url(id)
