Changing Index Page - Ruby on Rails - ruby-on-rails

I am new to rails so go easy. I have developed my blog and deployed it successfully. The entire app is based out of the post_controller. I am wondering how I can reroute the users path to default to the post_controller vs. the app controller.
To illustrate, if you go to http://mylifebattlecry.heroku.com you will see the default rails page. If you go to http://mylifebattlecry.heroku.com/posts you will see the the app. Once I complete this I will change my domain of http://www.mylifebattlecry.com to map to Heroku but need to know how to get the /posts to be where the visitor is sent.

You need to do two things
Delete the file /public/index.html
Update the file /config/routes.rb
map.root :controller => "posts" #RAILS 2
or
root :to => 'posts#index' #RAILS 3
This will then call the index action in your posts controller.
You will need to restart the application to see changes to routes.rb

Add the following line to your confing/routes.rb:
map.root :controller => "posts"
You need to restart your server after that.

Using Rails 2.3.8 I am trying to create a new view for a child object

So I have a pretty basic issue I guess. I'm using Ruby 1.8.7 and Rail 2.3.8 b/c the web host is pretty out of date. Anyways, I have an Event which has RSVPs associated with it. I have an administrator that I want to have access to a better view (more information_ of the RSVPs for the event.
The RSVP currently indexes like normal /events/1/rsvps which I get to using event_rsvps_path(event) and use an index.html.erb file. I made a adminindex.html.erb and put an adminindex in the rsvp controller. But now I don't know how to create a link to that adminindex.html.erb file.
The usual methods like link_to :controller=>'rsvps', :action=>'adminindex' don't work for obvious reasons to me.
The Routes file has map.resources :rsvps, :except => :update
Can someone tell me how to link the index to the adminindex file if the admin is signed in?
The problem is in your routes.rb file. Creating a resource only makes routes for the 7 RESTful actions (index, show, new, create, edit, update, destroy)
Since you have a custom action, you have to add a custom route for it. Try this:
map.resources :rsvps, :except => :update, :collection => { :adminindex => :get }
Run rake routes to see if it made the route correctly.

Understanding routing with rails

I am trying to make a stupid simple CMS for one of my clients using rails. I generated scaffolding for Page and have been successful at creating and rendering those pages, however, the routing is ugly.
Right now, if I want to view the home page, I get a url like this: example.com/pages/1
I'd like to accomplish 2 things:
How do I set the routing so that example.com automagically grabs the page named "home"
and
How do I set the routing so that example.com/page/page_name performs a
#page = Page.find_by name: 'page_name'
Q1:
How do I set the routing so that example.com automagically grabs the page named "home"
In `routes.rb:
root :to => '[controller]#[action]'
#'pages#home' for example, if your home page is in `pages_controller`
# and uses the `home` action
Q2:
How do I set the routing so that example.com/page/page_name performs a
#page = Page.find_by name: 'page_name'
match '/page/:name', :to => 'pages#some_name', :as => :some_name
this would generate the following in $rake routes:
some_name /page/:name(.:format) pages#some_name
when you link to (or redirect, or otherwise access) this page, you'd write
link_to "click this link!", some_name_path(#SomeModel.some_name)
To accomplish the first thing you need to open the file routes.rb which is in the config folder and add the following:
root to: "home#index"
I'm assuming you have a controller named home which contains a method called index and this is the one that displays the home page.
If you want to make it the same as example.com/pages then you would have to use
root to: "pages#index"
to make a general rule you need to use
root to: "controller#method"
Don't forget to remove the index.html from the public folder too.
I recommend you make the blog application presented here:
http://guides.rubyonrails.org/getting_started.html
It can help you understand more.
Here's a solution that assumes your controller is named pages_controller instead of page_controller.
Add these routes in config/routes.rb:
root to: 'pages#show', page_name: 'home'
get 'pages/:page_name', to: 'pages#show'
For the controller app/controllers/pages_controller.rb:
class PagesController < ApplicationController
def show
#page = Page.find_by(name: params[:page_name])
end
end
Note: In rails4 the find_by dynamic finders have been deprecated... so if you're app is on 4 you should look into updating them. These docs have further details.
Also, if you're just trying to get static looking urls then I would definitely go with Marian Theisen's suggestion and use friendly_id.

Get "home/index" in Rails project

After running rails generate controller home index in my Rails application, I see this line in routes.rb
get "home/index"
What does this line do? When I removed it, I didn't observe any difference it makes.
see the Rails Routing page for more info but...
It adds, to the routing table, an entry to direct a GET request of the form
http://localhost:3000/home/index
To the HomeController#index action, which will render a response and display the results to the user.
It is a shorthand notation for
match 'home/index' => 'home#index', :via => :get
To see what other routes your application has available, run the following from a terminal while inside your projects directory
rake routes

Rails 3 - changing index

I'm using Rails 3 and have the feeling that the syntax for changing the route for the index (http://localhost:3000) is different than from the former versions.
I'd like to open the dynamic index page (index.html.erb) of the employees-controller (which can be right now opened with localhost:3000/employees) as the default page (localhost:3000). I thought it's quite easy, because in the routes it's written:
# You can have the root of your site routed with "root"
# just remember to delete public/index.html.
# root :to => "welcome#index"
So that's what I actually did: I deleted public/index.html and set root :to => "employees#index".
But when I open the server and open localhost:3000, it's still opening the "welcome abroad!"-page. Pretty weird!
So I googled the problem and found answers which said, I should write this into my routes-file:
map.root :controller => 'employees', :action => 'index'
Same here - I also still get the "welcome abroad!"-page and the rails-shell says "undefined local variable or method 'map'". (I think this is the old syntax for Rails 2...?)
match "/" => "employees#index" says routing error: No route matches "/"
So what did I do wrong? How can I solve this problem?
Why you use "map" in Rails 3? Should be:
root :to => "employees#index"
I think problem is of cookies. please clear the cookies and the refresh the page.

A very basic issue with routes in ruby

I am new to ruby and while creating a sample application found out an issue that whenever I go to http://127.0.0.1:3000/people/index by default show action is executed and index is taken as a parameter. This is server log:
Started GET "/people/index" for
127.0.0.1 at 2010-12-23 18:43:01 +0500 Processing by PeopleController#show as
HTML Parameters: {"id"=>"index"}
I have this in my route file:
root :to => "people#index"
resources :people
match ':controller(/:action(/:id(.:format)))'
What is going on here and how can I fix the issue?
The route
resources :people
creates "sub"-routes
get '/people' => 'people#index'
get '/people/new' => 'people#new'
post '/people' => 'people#create'
get '/people/:id' => 'people#show'
get '/people/:id/edit' => 'people#edit'
put '/people/:id' => 'people#update'
delete '/people/:id' => 'people#destroy'
Actually, all of these sub-routes include (.:format) at the end of the recognized path.
The path /people/index would be recognized by the route /people/:id, mapping to the action #show.
The path /people would be recognized by the route /people, mapping to the action #index.
Use the URL helpers people_path and people_url for the /people route.
To get Rails to travel backward in time to before it espoused REST and to understand /people/index, do this:
resources :people do
get :index => 'people#index'
end

A couple things to keep in mind when working with your routes:
rake routes dumps the map of URLs to your controllers
When providing backwards compatibility, redirect the user to the correct path
I personally have yet to upgrade my app to Rails 3, and I'll be dragging my feet until I really need to do it (just got it out the door not too long ago). In Rails 2.x you had resource routes, but if you kept the default controller/action/id route it would fall through and resolve. It appears that is no longer the case in Rails 3. Essentially your resource routes handle all URLs in that resource namespace (/people in your case).
To provide backwards compatibility, I would add a redirect route to resolve that incompatibility.
match "/people/index", :to => redirect("/people")
The main reason for that is to prevent users from saving an incorrect URL for their personal links--while allowing legacy users to still be able to get where they meant to go.
Edit: New answer, removed pointing out the typo in the question.
