Rails Routes: Get Without Param :Id

Rails routes: GET without param :id

Resource routes are designed to work this way. If you want something different, design it yourself, like this.

match 'users/me' => 'users#me', :via => :get

Put it outside of your resources :users block

Why redirecting to #show action without passing the :id param work (in rails)?

I found this in Rails source:

Missing routes keys may be filled in from the current request's
parameters (e.g. +:controller+, +:action+, +:id+ and any other
parameters that are placed in the path).

So here :id exists in the current request params and it's used for this route.

Rails 3 Routes with or without :id

perhaps if you use the optional parameter as

# Routes
match 'product_specs/(:id)' => 'home#product_specs'

# Controller
def product_specs
  if params[:id].nil?
    product_specs = ProductSpecs.all()
  else
    product_specs = ProductSpecs.find(params[:id])
  end

Would something like that work?

Rails routes with :name instead of :id url parameters

params

The bottom line is you're looking at the wrong solution - the params hash keys are rather irrelevant, you need to be able to use the data contained inside them more effectively.

Your routes will be constructed as:

#config/routes.rb
resources :controller #-> domain.com/controller/:id

This means if you request this route: domain.com/controller/your_resource, the params[:id] hash value will be your_resource (doesn't matter if it's called params[:name] or params[:id])

friendly_id

The reason you have several answers recommending friendly_id is because this overrides the find method of ActiveRecord, allowing you to use a slug in your query:

#app/models/model.rb
Class Model < ActiveRecord::Base
  extend FriendlyId
  friendly_id :name, use: [:slugged, :finders]
end

This allows you to do this:

#app/controllers/your_controller.rb
def show
    @model = Model.find params[:id] #-> this can be the "name" of your record, or "id"
end

How do I call my show method without any parameters?

You can't, at least when you use resources — resources generates a standard group of routes that adhere to RESTful practices. In your case, it's generating get '/votes/:id', to: 'votes#show'

Because there is no matching param, it assumes that you're trying to go to votes#index

If you want to match both, I would do something like this in your routes.rb: get '/votes(/:id)', to: 'votes#show' the parens denote an optional param. You may need to put this prior to your resources block, or change your resources block to omit the show action.

Ruby on Rails routes - Query parameter vs id

Because you have a dynamic segment in the same position as :id you have to use constraints on your route.

https://guides.rubyonrails.org/routing.html#segment-constraints

# `restaurants/1` will be ignored
# `restaurants/anything-else` will be routed to RestaurantsController#index
get 'restaurants/:category',
   to: 'restaurants#index',
   constraints: { category: /[^0-9]+/ }

resources :restaurants

Alternate route to `create` - route without id fails

Try

resources :users do
  post :new, on: :collection
end

You need to specify the HTTP verb, action and the target. If the target is :member, then Rails expects an "id" parameter and constructs the URL based on that.

Make sure to read this guide on Rails routes.

Rails 3 resource routing without an id

You can use to_param to craft the rails uses

class Post < ActiveRecord::Base
  ...
  def to_param
    "#{year}/#{month}/#{day}/#{title.parameterize}"
  end
end

More info: http://api.rubyonrails.org/classes/ActiveRecord/Base.html#method-i-to_param and http://www.seoonrails.com/to_param-for-better-looking-urls.html

If you go this route, you'll want to create a permalink attribute, and use Post.find_by_permalink(params[:id]) rather than Post.find(params[:id])

i have to put a parameter in routes.rb

Try to change this on routes.rb
get 'api/forecast/service_name:' , to: 'api/forecasts#index'
