Invalid route name, already in use: 'user' - ruby-on-rails

I am trying to add followers to my rails application. I am seeing the following error when I run rails s to start my server:
Invalid route name, already in use: 'user' (ArgumentError)
You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here:
http://guides.rubyonrails.org/routing.html#restricting-the-routes-created
Routes
Rails.application.routes.draw do
devise_for :users
resources :users do
member do
get :following, :followers
end
end
resources :relationships, only: [:create, :destroy]
resources :posts do
member do
post '/like' => 'posts#like'
end
end
get ':username' => 'users#show', as: 'user'
root 'home#index'
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
end
It may be helpful to know that I added:
resources :users do
member do
get :following, :followers
end
end
resources :relationships, only: [:create, :destroy]
Before I added the above, my rails app worked.
I'm sure it's probably a simple fix, but I am new to rails. I've been tinkering with routes and searching online for over an hour, trying to understand and solve the problem. I'm hoping someone more knowledgeable can guide me in the right direction.

Since you are using devise there are some routes already created by devise_for users so avoid using such routes which has conflict with already defined routes. Instead of using as: :user put another relevant name like as::user_profile
Hope it helps

In your case, Devise routes and Users routes are conflicting. You need to change one of them. You can either put Devise under a specific prefix like,
devise_for :users, :path_prefix => 'auth'
resources :users
Reference: https://github.com/plataformatec/devise/wiki/How-To:-Manage-users-through-a-CRUD-interface

Please do not forget, that there is "as" option too.
devise_for :users, as: 'some_unique_prefix'

How to embed a route resource in a Devise route in Rails 6

Under normal circumstances if one wants to embed resources within other resources in Ruby on Rails in the routes.rb file it would look like this:
# routes.rb
resources :parents do
resources :children
end
The above will allow for a url like http://localhost:3000/parents/1/children.
My question is how to achieve the same result with the default devise_for :parents that exists in my routes.rb file?
I tried:
# routes.rb
devise_for :parents do
resources :children
end
and it did not work properly.
Any help is greatly appreciated!
devise_for only creates the routes related to signing up and in, so you would still use
resources :parents do
resources :children
end
in your routes for nested resource paths. There is a detailed answer here: Nested Resource with Devise - Rails3
If you generate the Devise controllers and views, you also need to specify those in your routes like this
devise_for :parents, controllers: {
sessions: 'parents/sessions',
registrations: 'parents/registrations'
}

devise (No routes Matches [put] "/users/edit.user)

ruby 2.3.3,
rails 5.1.6.1
I am trying to edit a user, after i click on the update, my app loads to this:
No route matches [PUT] "/users/edit.user"
# routes.rb
Rails.application.routes.draw do
devise_for :users
resources :posts
resources :projects
resources :contacts, only: [:new, :create]
get 'welcome/index'
root 'welcome#index'
get '*path' => redirect('/')
end
seems to be a problem with your routes.rb file
check this guide -> https://guides.rubyonrails.org/v5.0/routing.html#resources-on-the-web
from what I can tell you are not defining the routes pointing to your UsersController (devise_for :users doesn't do that, it defines completely other set of routes)
your routes.rb should look roughly like below:
Rails.application.routes.draw do
resources :users
...some other routes (like devise_for :users)
end
resources :users will define routes like /users for showing all user resource or /users/:id/edit for editing the user resource.
Now that you have those routes the will point to the UsersController class which should be defined in the users_controller.rb. In the controller you should define appropriate actions (like edit or update) that will update your user resource
I hope this is going to help solving your problem.

The action x could not be found for xyzController

I'm a beginner in Ruby on Rails and I have a problem. I'm trying to add comments to my app. Everything is working, but when I added this code to routes.rb
resources :galleries do
resources :comments, module: :galleries
end
resources :articles do
resources :comments, module: :articles
end
I can't update any gallery or article. My whole routes.rb:
Rails.application.routes.draw do
devise_for :users
resources :galleries do
resources :comments, module: :galleries
end
resources :articles do
resources :comments, module: :articles
end
match ':controller(/:action(/:id))(.:format)', via: [:post, :get]
root 'public#index'
end
It looks like the request (articles/12?page_id=4) is falling through to the match statement and not getting picked up by your resources. Your match statement:
match ':controller(/:action(/:id))(.:format)', via: [:post, :get]
is matching "articles" as the controller, and looking for "12" as the action and it clearly can't find it.
I would scrap the match statement and go strictly with named routes or resourceful routing permanently, or at least while debugging. Next, run
rake routes
and check the results. From your routes.rb I am guessing you will have a line like this:
article GET /articles/:id(.:format) articles#show
If that is indeed the case, make sure you have the show() method defined in the articles controller, and verify that the logs are showing a GET request for it.

How to change a route name rails 4

I changed the routing of posts#index to match blog and I now get /blog in the URL which I was trying to accomplish.
I've tried several different things to get my actual blog post which the route currently looks something like /posts/this-is-a-test to also use blog rather than posts in the URL.
Below is my current route file. I am using the friendly_id gem, if that makes any difference in answering this question.
resources :posts do
resources :comments
end
resources :contacts, only: [:new, :create]
root "pages#home"
get "/home", to: "pages#home", as: "home"
get "about" => 'pages#about'
get "pricing" => 'pages#pricing'
get "contact_us" => 'pages#contact_us'
match 'blog', to: 'posts#index', via: :all
end
path option along with resource must help.
resources :posts, :path => 'blogs' do
resources :comments
end
This will change all /posts and /post to /blogs/ and /blog.
If you want to change your route's helper methods such as posts_path to blogs_path and new_post_path to new_blog_path etc, you can change it with as tag.
resources :posts, :path => 'blogs', :as => 'blogs' do
resources :comments
end
Or yet better, you can specify the controller and route blogs directly as:
resources :blogs, controller: 'posts' do
resources :comments
end
This is the awesomeness of Rails! :)
match 'blog/:id' => 'posts#show'
should work. But if you want to match every method in posts controller to blog (and you don't want to use the posts path), I would just rename the controller to blog instead and add resource :blog in the routes.
This helped me, from official guides documentation, add this in your routes.rb file:
get '/patients/:id', to: 'patients#show', as: 'patient'

How do I nest devise users with other models?

I just made a new app, and am wondering how I would route it. A user has_many companies,but how how do I route it so? I am using devise.
::Application.routes.draw do
devise_for :users do
resources :companies
end
root :to => "home#index"
end
I'd suggest separating between devise routes and other app routes:
devise_for :users, :path => 'accounts'
resources :users do
resources :companies
end
This also means that devise will use /accounts/* instead of /users/* for its authentication paths and so /users/* will remain free for your use.
You can also look at devise's routing documentation.
