how to fetch the route i.e path of my current api in routes.rb file

rails show routes
rails routes constraints
rails routes redirect
rails routes with params
rails path helper
rails routes match
rails conditional routes
rake routes

I'm new to rail. I have few clarifications, which I have listed below.

  1. I have referred many links and stack overflow questions, everywhere it's mentioned to use request and fetch the details regarding the path, controller, action etc. but if I use request in my routes.rb it throws undefined local variable or method error.

  2. I used constraints in my routes.rb and from there it calls a method matches? from a class where dynamic constraints are defined inside lib/constraints directory. In here the matches?(request) receives a parameter named request, which has details about current route, from where the parameter value is sent?, I have this doubt because while using this method inside routes.rn in constraint(ClassName) I'm not sepecifying the method name (matches?) or the parameter request

I would like to know the working of things behind the scene.

Thank You

Rails Routing from the Outside In, How to automatically create paths and URLs using route helpers. The routes for your application or engine live in the file config/routes.rb and typically looks like this: To fix this, move the get line above the resources line so that it is matched first. returns the same path prefixed with the current host, port, and path prefix. Path From Route The Path from Route function provides an easy method for searching along the corridor defined by a route. The function provides the times/distances needed to reach a set of Locations from an existing route.

If you have URIs:

localhost:3000/users/:id
localhost:3000/users
localhost:3000/users/new
....

You can do something like

rake routes | grep user

in order to get only those that contain user in its path name.

Hope this helps..

Routing, It can also generate paths and URLs, avoiding the need to hardcode strings in your views. In Rails apps, routes are usually placed in the config/routes.rb file. constraints(ip: /127\.0\.0\.1$/) do get 'route', to: "controller#action" end.

Routing is how Web API matches a URI to an action. Web API 2 supports a new type of routing, called attribute routing.

conventionally you don't access the current path in the routes.rb, at least as how it seems you're asking to access it. There are a number of different matching methods and techniques used in the rails router that serve the utility I imagine your looking for.

Can you share exactly why you want to access the curret route in the routes.rb file?

  • no, Rails.application.routes.routes this one gives list of all routes, my question is instead of getting all route how to fetch the route of my current url in routes.rb
  • HI @NarayananV where do you want to fetch it ? at controller at any action?
  • I need to fetch at routes.rb, as mentioned in question 1. I referred few stack questions, it instructed me to use request.path but it threw me an undefined variable error, Is there any other way to get the url path in routes.rb?
  • @NarayananV I can't get you, it would be better if you can show an example what are you looking for.
