I am getting an undefined method stripe_managed_accounts_path when trying to create a new resource via typical rails forms. Below is my code, I am dumbfounded, cannot figure it out.
Controller
class StripeManagedAccountsController < ApplicationController
before_action :authenticate_printer!
def new
#stripe_managed_account = StripeManagedAccount.new(printer_id: current_printer.id)
end
end
model
class StripeManagedAccount < ActiveRecord::Base
belongs_to :printer
end
views/new
<h1>Create New Stripe Managed Account</h1>
<%= render 'form' %>
view/form
<h5>inside the form</h5>
<%= form_for #stripe_managed_account do |f| %>
<% end %>
routes
resources :printers, only: [:show, :edit, :update] do
resources :stripe_managed_accounts
end
error
`undefined method 'stripe_managed_accounts_path' for #<#<Class:0x007fc627d342b8>:0x007fc62b36e108>`
routes
printer_stripe_managed_accounts GET /printers/:printer_id/stripe_managed_accounts(.:format) stripe_managed_accounts#index
POST /printers/:printer_id/stripe_managed_accounts(.:format) stripe_managed_accounts#create
new_printer_stripe_managed_account GET /printers/:printer_id/stripe_managed_accounts/new(.:format) stripe_managed_accounts#new

PATCH /printers/:printer_id/stripe_managed_accounts/:id(.:format) stripe_managed_accounts#update
PUT /printers/:printer_id/stripe_managed_accounts/:id(.:format) stripe_managed_accounts#update
DELETE /printers/:printer_id/stripe_managed_accounts/:id(.:format) stripe_managed_accounts#destroy
and it is highliting this line <%= form_for #stripe_managed_account do |f| %>
I have grepped the entire code base for stripe_managed_accounts_path and it is no where. I am at odds end...
UPDATE:::
If I add that route it disappears??? Why is it looking for that route. Is it becasue of how I named my fodlers, etc??
You're nesting stripe_managed_accounts inside printers on your routes file. If you take a look at the output of rake routes, you can see that there isn't a path for stripe_managed_accounts_path.
You can either use the shallow option on the stripe_managed_accounts resource or adjust your form to include the printer which the managed account will belong to.
#controller
class StripeManagedAccountsController < ApplicationController
before_action :authenticate_printer!
def new
#stripe_managed_account = current_printer.build_stripe_managed_account
end
def create
current_printer.stripe_managed_accounts.create stripe_managed_account_params
# handle response
end
def stripe_managed_account_params
params.require(:stripe_managed_account).permit([list of attributes])
end
end
#form
<h5>inside the form</h5>
<%= form_for [current_printer, #stripe_managed_account] do |f| %>
<% end %>
That will generate the proper url, nesting the stripe_managed_account inside the current printer.

I tried hard to find this exact match of my error but I am unable to do so. I am new to Ruby and stuck for long after this block. Please help.
I have checked my route.rb file my controller method show and my show.html.erb file error remains.
I destroyed and created controller again and again to check but still the error remains.
Is it asking me to define/declare variable user?? have not I did so?? like in controller i did #user and then called databsae.. I think so.
Thanks in advance
The controller:
class PersonsController < ApplicationController
def show
#user = Users.find(params[:id])
end
end
The view:
<%= provide(:title, #user.name %>
<h1> #user.name </h1>
<%=#user.name %>, <%=#user.email %>
The routes:
Rails.application.routes.draw do
get 'persons/show'
root 'staticpages#home'
get 'help' => 'staticpages#help'
get 'about' => 'staticpages#about'
resources :persons
resources :person
end
Model names in Rails are singular:
#user = User.find(params[:id])
I've an issue with the paths in the views and I don't know how to solve it.
I've "categories" that has_many "posts" and "posts" that belongs_to "categories".
1.- I want to show on home page the truncate last post of an specific category (the ID number "1"). Then I want that post to link to the show post path but I get this error:
"Unknow Action
The action 'index' could not be found for PostsController"
I think I've my paths wrong because I don't need the index view because I'm only going to show that specific post. So, I think that category_posts_path(#last_post) is not the right path (I don't know where to look for more info about making the route path in the views...). Actually, the browser is showing me that is looking for the "2" category when it is a post of the "1" category...? What am I doing wrong?
This is the browser route:
http://localhost:3000/en/categories/2/posts
This is my views/categories/home.html.erb file:
<div class="post_details">
<h2><%= #last_post.title %></h2>
<%= image_tag #last_post.image(:header), class: "post_image" %>
<p><%= truncate #last_post.body, length: 100 %></p>
<p class="button"><%= link_to "READ MORE", category_posts_path(#last_post) %></p>
</div>
2.- I have another path problem in the views/categories/show.html.erb file. I have a loop to show all the post of one specific category, but when I link in some post (to show it) there is the "index" error again:
"Unknow action
The action 'index' could not be found for PostsController"
This is the browser route:
http://localhost:3000/en/categories/1/posts
This is the views/categories/show.html.erb file:
<div class="post_details">
<h2><%= link_to post.title, category_posts_path(post) %></h2>
<%= image_tag post.image(:header), class: "post_image" %>
<p><%= post.body %></p>
</div>
This is the categories_controller.rb file:
class CategoriesController < ApplicationController
before_action :get_categories
def index
end
def show
#category = Category.find(params[:id])
end
def home
if params[:set_locale]
redirect_to root_url(locale: params[:set_locale])
else
#category = Category.find_by_id(1)
#last_post = #category.posts.order("created_at desc").first
end
end
def get_categories
#categories = Category.all.order("rank asc, name asc")
end
end
This is my posts_controller.rb file:
class PostsController < ApplicationController
def show
#category = Category.find(params[:category_id])
#post = #category.posts.find(params[:id])
end
end
This is my route.rb file:
scope '(:locale)' do
resources :categories do
resources :posts
end
resources :contacts
root 'categories#home'
get "/contact" => "contacts#new"
# static pages
get "/investment" => "contents#investment"
get "/partner-with-us" => "contents#partner", as: "partner"
get "/our-companies" => "contents#companies", as: "companies"
get "/site-map" => "contents#sitemap", as: "sitemap"
get "/terms-and-conditions" => "contents#terms", as: "terms"
get "/privacy" => "contents#privacy"
end
When you are nesting routes you should always consider what is the parent and whats a child in given route. Since your paths don't know anything about your associations you have to explicitly define every object in the nesting.
I.e. since you nested posts in categories linking to last post in given category would look like this:
category_post_path(#category, #last_post)
(I think you have also a typo there - category_posts_paths - which links to posts index index - hence the error. Use category_post_path. instead, and give it both parent category and the post.
You can run rake routes to see exact information on paths (or go to http://localhost:3000/rails/info/routes )
I have a route like this.
get 'mypage' => 'mypage#browserUpdate'
I added a controller called:
mypage_controller.rb
class MypageController < ApplicationController
def browserUpdate
puts "browser_update controller working"
end
end
In my views folder I have a folder called.
mypage > browserUpdate.html.erb
When i put a link in the application.html.erb
<div><%= link_to 'UPGRADE PATH', mypage_path %></div>
When I click the link I get an error:
Assertion failed: The URL '/mypage' did not match any routes in your
application
Rake routes says. mypage GET /mypage(.:format) mypage#browserUpdate
Anyone know what I'm doing wrong here.
I think your controller should be plural, i.e. it should be mypagescontroller.
routes.rb
get 'mypage' => 'mypage#browserUpdate', as: 'browser_update'
application.html.erb
<%= link_to 'UPGRADE PATH', browser_update_path %>
This should help.
I'm fairly new to Ruby on Rails and I'm having what seems like an easy problem but I can't seem to figure out what I have done wrong. My homepage has a button and when you click the button, its supposed to create an xml file with information from the database.
Button code:
<%= button_to "Create Google File", :action => :create_google_file %>
Controller code:
class ProductsController < ApplicationController
def new
end
def create_google_file
#products = Product.find(:all)
file = File.new('dir.xml','w')
doc = #products.to_xml
file.puts doc
file.close
end
end
The error I'm getting is
No route matches {:action=>"create_google_file", :controller=>"products"}
Add this to your config/routes.rb file
match "/create_google_file" => "products#create_google_file", :as => :create_google_file
And change the button to this
<%= button_to "Create Google File", create_google_file_path %>
