Rails form_for not working as expected

Question

I am trying to create a small rails blog, and have run into an error. I think I've messed up the naming convention of something here... but I can't find anything specific enough to help me and give me the answer.

I have a route of

resources :blog

and a controller which has the following

class BlogController < ApplicationController

  def index
    @blogs = Blog.all
  end

  def show
    @blog = Blog.find(params[:id])
  end

  def new
    @blog = Blog.new
  end

end

When I try to set up a form on the new.html.erb page, it links to routing which states

undefined method `blogs_path'

My route is blog, not blogs... where am I going wrong? I would like the route to be /blog.

I'd recommend saying resources :blogs as resources are usually in plural form. — Ilya Bodrov-Krukowski

Following the conventions, rename your controller file to blogs_controller.rb and the class inside of it to BlogsController. Then, in your routes.rb: resources :blogs. It should all work fine.

Thanks for the help. I went back and set up the blog using the standard naming convention.

As already said, it should be :

resources :blogs

And I think the controller should use the plural too : BlogsController

To find what's wrong with urls you can use rake routes command

Values in first column Prefix are names of helpers you can use as prefix_url or prefix_path
