Imagine this. I'm on the URL http://localhost:3000/companies/3, and on this view, I want an employees button that takes me to http://localhost:3000/companies/3/employees
In my routes file, I have
namespace :companies, :only => [:index, :show, :new, :edit, :destroy], :path => "/:companies" do
resources :employees, :only => [:index, :edit, :new, :show] do
end
end
I understand that I need to link to the index action of 'employees', but I don't know what to add to my companies 'show' page. Right now, it looks like
%a{title: "company1", href: "#"} Employees
(I am using haml, but feel free to post your answer in erb)
In rake routes, I get
companies_employees GET /:companies/employees(.:format) companies/employees#index
... but I want companies/company_id/employees
Thanks!
link to employees in the company show page
<%= link_to 'Employees', company_employees_path(#company) %>
employees controller
def index
#company = Company.find(params[:company_id])
#employees = #company.employees
end
routes
resources :companies do
resources :employees
end
rake routes
company_employees GET /companies/:company_id/employees(.:format) employees#index

Im trying to implement a feature on my project, so users can change their profile picture. I'm currently at the point where everything on the front end works (when you hover the mouse over the image it shows camera and when you click it, you can browse through your computer to select an image file) Yet, it doesnt work after that point.
I'm not really sure how to handle server request.
FYI
im using routes.rb and controller .rb files to handle backend.
Also,
should i use iframe, instead of form tag in html?
Thanks!
You don't need an iFrame. Simple form-for ruby helper will help in this case. I will suggest you to use a file-uploading gem like paperclip.
Create a model for your records:
class User < ActiveRecord::Base
has_attached_file :avatar, :styles => { :medium => "300x300>", :thumb => "100x100>" }, :default_url => "/images/:style/missing.png"
validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/
end
(I am supposing the model name to be user)
Create a new migration with generator:
rails generate paperclip user avatar
Update your html form as follow:
<%= form_for #user, :url => users_path, :html => { :multipart => true } do |form| %>
<%= form.file_field :avatar %>
<% end %>
Then do following changes in the controller:
def create
#user = User.create( user_params )
end
private
def user_params
params.require(:user).permit(:avatar)
end
To display image anyware on the page use the following helper:
<%= image_tag #user.avatar.url %>
This is the easiest way to handle image uploading at server side in rails. You can read more at the paperclip github page.If you don't want to use a gem then then there is a ruby class FileUtils which can help you in achieving same goal.
New to Rails. I have a model named Admin in my rails application. when i tried to delete the session i am getting No route Match Error.
I have created session controller to manage sessions shown below
class AdminSessionsController < ApplicationController
before_action :confirm_logged_in, :except => [:new, :create, :destroy]
def destroy
session[:admin_id] = nil
flash[:notice] = "You are now logged out"
render("new")
end
end
Routes I defined in routes.rb
resources :admin_sessions, only: [:new, :create, :destroy]
I have link in some other view to delete a session
<%= link_to "Sign out", :controller => "admin_sessions", :action => "destroy" %>
And I am getting the following Error
No route matches {:action=>"destroy", :controller=>"admin_sessions"}
Please help somebody!
You define resources while it's resource. You do not depend on specific id, so it always should respond with one resource (DELETE /admin_sessions/id vs DELETE /admin_sessions). Change in your route resources to resource and it will work.
I'm using padrino with my website, and need to override the default layout to use a different layout in certain situations i.e. when a user clicks on a certain thing.
Padrino documentation gives these examples:
SimpleApp.controllers :posts do
# Apply a layout for routes in this controller
# Layout file would be in 'app/views/layouts/posts.haml'
layout :posts
get("/posts") { render :haml, "Uses posts layout" }
end
SimpleApp.controllers :admin do
get :index do
render "admin/index", :layout => :admin
end
get :show, :with => :id do
render "admin/show", :layout => false
end
end
I have a recommendation that is nested below Categories and Awards.
So Category/:id/awards/:id/recommendations/:id
I have an Assets model that handles paperclip attachments to the Recommendation. A Recommendation has_many Assets, Assets belong_to :recommendation
In my Recommendation new/edit views I am rendering a form partial (as is normal) that gives the user the option to upload several assets.
If there are Assets already related, then it lists them. I am working on setting up a custom delete action on the recommendations controller.
My current link_to:
<%= link_to "Delete Attachment",
{:controller => :recommendations, :action => :destroy_asset, :id => asset.id },
{:remote => "true", :confirm => "Are you sure you want to delete this image?"}
%>
My Controller action:
def destroy_asset
##recommendation = Recommendation.find(params[:id])
#asset = Asset.find(params[:id])
#asset.destroy
respond_to do |format|
format.js
end
end
routes:
resources :recommendations
resources :categories do
resources :awards do
resources :recommendations
end
end
I am still learning remote => true, and how to route this sucker. Not sure if I need to have the route nested or not. I tend to think not. Since I have an Asset.id in my loop, I should just be able to execute the destroy without needing the Recommendation at all.
So the question/s: do I need a route to access a custom action in my recommendations_controller?
thanks
Try this:
resources :categories do
resources :awards do
resources :recommendations
member do
get :destroy_asset
end
end
end
end
Or If you only want only destroy_asset action under recommendation controller, do something like this :
resources :recommendations
member do
get :destroy_asset
end
end
Or If you want custom match, do something like this :
match "asset/:id/destroy_asset", :to => "recommendations#destroy_asset",
:as=> "destroy_asset"
I am using Ruby on Rails 3 and I would like to change its conventional behavior on posting a form in order to post from a signup action to the create action instead that from the new action. That is, I would like to use the signup action instead of the (conventional) new action in my User controller and trigger the create action to save my model data that contains nested resources.
In my /config/routes.rb file I have:
resources :users do
collection do
get 'signup'
end
resource :profile
end
In my /app/controllers/users_controller.rb I have
class UsersController < ApplicationController
def signup
#signup_user = User.new(params[:user])
#signup_user.build_profile # NOTE: Nested resource
...
end
def create
...
#signup_user.save
respond_to do |format|
format.html { render :action => :signup } # signup.html.erb
end
end
end
In my /app/views/users/signup.html.erb file I have
<%= form_for #signup_user do |f| %>
...
<% end %>
My problem is that if I submit the above form, I will be redirected to the index action of the user controller and not to the create action I expect. It seams that the form posts only to the index action.
How can I solve the problem?
I tryed to use the following
<%= form_for( :user, #signup_user, :url => { :controller => "users", :action => "create" }, :html => { :method => :post } do |f| %>
but I have still the problem: I am redirected to the index action.
SOLUTION
The problem did seam to be in the routers.rb. The correct code was
resources :users do
collection do
get 'signup'
post 'create'
end
resource :profile
end
