I have this action inside a mailer template in Ruby on Rails 3.2:
# password_reset.text.erb
<%= edit_password_reset_path(#user.password_reset_token) %>
Unfortunately, when I hit that link I get a strange routing error:
No route matches {:action=>"edit", :controller=>"password_resets", :locale=>"Ze92D45dUPpfwsgbFmpYeg"}
It is strange that the locale seems to contain the password_reset_token here rather than the locale (e.g. en or de).
So I guess that edit_password_reset_path is not getting localised automatically and that is causing the error?
How could that be fixed?
Here's some more info:
class PasswordResetsController < ApplicationController
def edit
#user = User.find_by_password_reset_token!(params[:id])
end
end
# routes.rb
scope '(:locale)' do
resources :password_resets
....
end
You need to send the token as a query param:
edit_password_reset_path(#user, password_reset_token: #user.password_reset_token)
# Passing in the #user fulfills the :id section of the url.
By doing edit_password_reset_path(#user.password_reset_token) you are providing the reset token to the :locale section.
To provide locale as well:
edit_password_reset_path(#user, locale: "de", password_reset_token: #user.password_reset_token)

I'm using Padrino, and I want to take parameters out of URL and use them in an .erb template.
In my app setup I have:
get '/testpage/:id' do
userID = params[:id]
render 'test/index'
end
In my test/ folder I have index.html.erb which is successfully rendered, for a url like http://localhost:9000/testpage/hello123.
However, I've tried printing the params[:userID] on the page with:
<%= #userID %>
The rest of the page renders fine but hello123 isn't anywhere to be found. When I try <%= userID %> I get undefined local variable or method `userID' for #<stuff>
What am I missing here?
Just a guess, because I've never used Padrino, but if it works like Rails this may help you:
get '/testpage/:id' do
#userID = params[:id]
render 'test/index'
end
In sinatra, it's just like this (see "Views/Templates" section):
get '/testpage/:id' do |id|
erb :index, :locals => {:id => id}
end
The template is located in views/index.erb by default. It could be change.
Our websites should allow to show different contents related to the given url .. something like a multisite in wordpress where we have one installation and serve the content according to the url.
as it is necessary to have the routes in the correct language I want to use a "dynamic route" approach to serve the right content. My problem is now that I dont find a way how to serve the proper routes in routes.rb if they are dynamic.
How can I "access" or "pass" the request object into any method inside the routes.rb file
f.e. like this
routes.rb
Frontend::Application.routes.draw do
DynamicRouter.load request
end
app/models/dynamic_router.rb
class DynamicRouter
def self.load request
current_site = Site.find_by_host(request.host)
Frontend::Application.routes.draw do
current_site.routes do |route|
get "#{route.match}", to: "#{route.to}"
end
end
end
end
this doesnt work because request is undefined in routes.rb
To answer your question: How can I "access" or "pass" the request object into any method inside the routes.rb file Obtain it as ENV object from rack middleware.See code below
# lib/dynamicrouterrequest.rb
require 'rack'
class DynamicRouterRequest
def initialize(app)
#app = app
end
def call(env)
request=Rack::Request.new(env)
ENV["OBJ_REQUEST"]=request.inspect.to_s
#app.call(env)
end
end
Grab it again in routes
# routes.rb
Frontend::Application.routes.draw do
request=ENV["OBJ_REQUEST"]
DynamicRouter.load request
end
A possible soluction is to create the default rules on routes.rb and add a rack middleware that can transform a path according to the domain
# routes.rb
get '/category/:id', :to => 'categories#show'
In the middleware you can transform a path like 'categoria/:id' to '/category/:id' if the domain matches '.es', before the application hits the router layer.

My data of a datatable:
def data
theusers.map do |usermap|
[
h(usersmap.spriden_last_name),
h(usermap.spriden_first_name),
h(usermap.spriden_id),
link_to(usermap.gobtpac_username, detail_path(usermap.spriden_id))
]
end
end
the above code resides in app\datatables\helpdesk_datatable.rb
The above works mostly I know it is getting the data, the error I get is with the detail_path
Error on "undefined method" for detail_path... This means it is not building the router dynamically right, correct?
Or I am passing in the wrong thing I tried to pass in usermap.spriden.id and just banner user, same issue. I am really not sure how routes work apparently. I have a details_controller.rb in controllers that has a show method in it and i have the views/details/show.html.erb which will show the data that was passed into the route, at least I thought. But is it just an ID or an object? so if it just an id i have to look it up again in
the show method right? How do routes like this look? I am using devise and cancan too here is my routes file:
NmsuMyaccount::Application.routes.draw do
authenticated :user do
root :to => 'home#index'
match 'home', :to => 'home#index', :via => :get
end
#get 'show-details' => "details#show", as: 'show_details'
resources :details
devise_for :users
resources :users
# In order for an unauthorized user access this controller#action, this needs to be in a scope, but I don't know why.
devise_scope :user do
match 'home', :to => 'home#index', :via => :get
end
end
Also hitting the end point localhost:3000 is an error, I have to goto /home, although devise does work just fine. So thought I was close but for the life of me cannot get the detail_path to work, and I thought it was a plural issue so tried details, and just detail no path etc. No dice.
I don't believe that you have access to the route helpers that Rails provides inside your custom class. So you have to manually include the module inside your class. Something like:
link_to(usermap.gobtpac_username, Rails.application.routes.url_helpers.detail_path(usermap.spriden_id))
Or:
include Rails.application.routes.url_helpers
# Use it like you are using.

Can Rails Routing Helpers (i.e. mymodel_path(model)) be Used in Models?
I'm working on a Rails 3.2 application with the following routing conditions:
scope "(:locale)", locale: /de|en/ do
resources :categories, only: [:index, :show]
get "newest/index", as: :newest
end
I've a controller with the following:
class LocaleController < ApplicationController
def set
session[:locale_override] = params[:locale]
redirect_to params[:return_to]
end
end
I'm using this with something like this in the templates:
= link_to set_locale_path(locale: :de, return_to: current_path(locale: :de)) do
= image_tag 'de.png', style: 'vertical-align: middle'
= t('.languages.german')
I'm wondering why there doesn't exist a helper in Rails such as current_path, something which is able to infer what route we are currently using, and re-route to it include new options.
The problem I have is using something like redirect_to :back, one pushes the user back to /en/........ (or /de/...) which makes for a crappy experience.
Until now I was storing the locale in the session, but this won't work for Google, and other indexing services.
I'm sure if I invested enough time I could some up with something that was smart enough to detect which route matched, and swap out the locale part, but I feel like this would be a hack.
I'm open to all thoughts, but this SO question suggests just using sub(); unfortunately with such short and frequently occurring strings as locale short codes, probably isn't too wise.
If you are using the :locale scope, you can use url_for as current_path:
# Given your page is /en/category/newest with :locale set to 'en' by scope
url_for(:locale => :en) # => /en/category/newest
url_for(:locale => :de) # => /de/kategorie/neueste
In case somebody looks here, you can use request.fullpath which should give you all after domain name and therefore, will include locale.
I am trying to get my customized home page to appear instead of the Welcome Aboard You're Riding Ruby on Rails default page. In my config/routes.rb file I have the line root :to => 'pages#home' to let it load the pages/home.html.erb file, and I removed public/index.html as instructed in the comments of the routes.rb file. All the other web pages which I used the syntax match "/page_name", :to => "pages#page_name" are working fine. What more do I need to do to update my home page?
EDIT:
Someone asked me to post my pages controller. Here it is:
class PagesController < ApplicationController
def home
#title = "Home"
end
def contact
#title = "Contact"
end
def about
#title = "About"
end
def help
#title = "Help"
end
end
The #title variable is referred to in my .html.erb files, but otherwise my controller is pretty much empty.
Have you tried restarting the server after deleting index.html? Did you clear your browser cache?
Do you have a PagesController?
rails generate controller pages home
The syntax I use (Rails 2.3) is:
map.root :controller => "welcome"
That goes to the :index method. If you want to go to :home, I presume you would add :action.
