Rails Routes Resources Member Issue - ruby-on-rails

I have created a nested routes like this
resources :subjects do
resources :subject_edits do
member do
post :vote
end
end
end
when I run rake routes, I found it exited
vote_subject_subject_edit POST /subjects/:subject_id/subject_edits/:id/vote(.:format) subject_edits#vote
but when I use it in my .erb file
<%= button_to 'I Agree', :action => vote_subject_subject_edit_path(#subject, #edit) %>
I got an error,
No route matches {:action=>"/subjects/25/subject_edits/1/vote",
:subject_id=>"25", :id=>"1", :controller=>"subject_edits"}
what is wrong here?

This helper sets url explicitly, so you need:
<%= button_to 'I Agree', vote_subject_subject_edit_path(#subject, #edit) %>
without passing :action option.

Rails run :get route within /new and /edit _form

I have a _form for new and edit for a #Giveaway object. Within this form I have a field for a random winner.
I want to populate this field by calling the method giveaways#random_winner with <%= button_to "Randomly Pick Winner!", {:action => 'choose_winner'}, :method => :get %>, but I am getting this error No route matches {:action=>"choose_winner", :controller=>"giveaways"} when loading /giveaways/new.
Here is my controller:
def choose_winner
random_winner = SubscriberUser.where(user_id: current_user.id).pluck(:subscriber_id).sample(1)
session[:random_winner] = random_winner
redirect_to :back
end
Here are the routes that I have tried. I'm not very good at non-scaffold routes yet:
resources :giveaways do
member do
get 'choose_winner' => 'giveaways#choose_winner'
#tried get :choose_winner, as: :choose_winner
#tried get 'new/choose_winner'
#tried get 'choose_winner'
#tried get 'choose_winner', to: 'giveaways#choose_winner', as: 'choose_winner'
end
end
Question -- Why is the page not loading when I have defined the controller and action in the route? Will I have to reload the page when I do run that route... is there a better way to get at this data?
Your routes.rb is close
resources :giveaways do
member do
get :choose_winner
end
end
And then I would use a Rails route helper so you don't have to worry about setting the action/controller yourself.
<%= button_to "Randomly Pick Winner", choose_winner_giveaway_path(#giveaway), method: :get %>

form_for routing error with scope :module nested routes

This may not make sense but I'm trying to learn harder stuff and progress, it seems like I'm missing the ID for address but can't seem to find a solution.
I included the url in form_for because when I remove it, the app breaks. But seems like I predefined the url than edit breaks.
<%= form_for([#address.user, #address], :url => user_addresses_path) do |f| %>
Error Readout:
No route matches [PATCH] "/users/1/addresses"
When I remove :url=>
undefined method `user_client_address_path'
routes.rb
Rails.application.routes.draw do
# Security Devise Setup
devise_for :admins
devise_for :users
# Main Pages
root 'website/page#index'
# Client Sections
resources :users do
scope module: "client" do
root :to => 'dashboard#index'
resources :addresses
end
end
namespace :admin do
root :to => 'panel#index'
end
end
rake routes partial output (let me know if more is needed)
user_addresses GET /users/:user_id/addresses(.:format) client/addresses#index
POST /users/:user_id/addresses(.:format) client/addresses#create
new_user_address GET /users/:user_id/addresses/new(.:format) client/addresses#new
edit_user_address GET /users/:user_id/addresses/:id/edit(.:format) client/addresses#edit
user_address GET /users/:user_id/addresses/:id(.:format) client/addresses#show
PATCH /users/:user_id/addresses/:id(.:format) client/addresses#update
PUT /users/:user_id/addresses/:id(.:format) client/addresses#update
DELETE /users/:user_id/addresses/:id(.:format) client/addresses#destroy
If you are using AJAX to submit the form, try adding method: 'POST' to it.
If you are submitting the form normally, try adding method: :post to the form_for hash.
It should end up something like:
<%= form_for([#address.user, #address], url: user_addresses_path, method: :post) do |f| %>

Rails 4 shallow nesting UrlGenerationError, missing required keys

I'm trying shallow nested resources for the first time and having a little trouble with one my index routes.
routes.rb
resources :sites, shallow: true do
resources :visits
end
The error I get is in my visits#show page's back button:
<%= link_to 'Back', site_visits_path(#site) %>
No route matches {:action=>"index", :controller=>"visits", :site_id=>nil} missing required keys: [:site_id]
In the index action of my VisitsController I set#site as follows:
#site = Site.find(params[:site_id])
However it's saying my :site_id is nil and I'm not sure how to set this correctly.
You can set that like:
<%= link_to 'Back', site_visits_path(:site_id => #site.id) %>

Rails 3 Routing: non-CRUD controller

I need a bit of help with converting routing from Rails 2 to Rails 3.
In app/views/layouts/application.html.erb, I have:
<%= link_to "Reports", reports_path %><br>
There is a ReportsController, and in app/views/reports/index.html.erb, I have this:
<%= link_to "Clients With Animals", :action => "getAnimals", :controller => "clients" %>
Then, in config/routes.rb, I have this (Rails 3)
match '/reports' => "reports#index"
match '/clients/getAnimals', to: "clients#getAnimals"
I get this error when I click on the "getAnimals" link on the reports page:
ActiveRecord::RecordNotFound in ClientsController#show
Couldn't find Client with id=getAnimals
I don't want "getAnimals" to be the ID - I want it to be the action, instead.
How do I do that?
Assuming you also have a resources :clients entry, you want to make sure match '/clients/getAnimals', to: "clients#getAnimals" is above it (Rails will match whatever it hits first).
However, the better way may be to put it in the resource:
resources :clients do
get 'getAnimals', :on => :collection
end

Rails: using nested named routes

routes.rb:
resources :jobs do
resources :activitylogs
end
rake routes:
...
POST /jobs/:job_id/activitylogs(.:format) {:controller=>"activitylogs", :action=>"create"}
new_job_activitylog GET /jobs/:job_id/activitylogs/new(.:format) {:controller=>"activitylogs", :action=>"new"}
edit_job_activitylog GET /jobs/:job_id/activitylogs/:id/edit(.:format) {:controller=>"activitylogs", :action=>"edit"}
...
How do I use the route new_job_activitylog?
Doing <%= new_job_activitylog %> gives undefined exception - so does using link_to which most of the examples I see are using.
Use
<%= new_job_activitylog_path %>
or
<%= new_job_activitylog_url %>
_path returns a relative path, while _url returns a complete url including http://domain.com if you've set it in your config.
To use those route names, I just had to append _path to them.
So: new_job_activitylog is undefined, but new_job_activitylog_path is a method in the view that takes the job id as a parameter.
<%= link_to 'new', new_job_activitylog_path(:job_id => #job.id) %>
works!
