Activerecord::Recordnotfound in Articlescontroller#Show Couldn't Find Article Without an Id

ActiveRecord::RecordNotFound in ArticlesController#show Couldn't find Article without an ID

You are redirecting before actually saving your article.

This:

def create
  @article = Article.new(article_params)
  redirect_to @article
  @article.save
end

should be:

def create
  @article = Article.new(article_params)
  @article.save
  redirect_to @article      
end

And if you want to add some error handling as well:

def create
  @article = Article.new(article_params)
  if @article.save
    redirect_to @article
  else
    render :new
end

ActiveRecord::RecordNotFound in ArticlesController#show Couldn't find Article with 'id'=edit

Then that's the cause of the error. 'edit' page requires an id param otherwise. as in your controller:

def edit 
 @article = Article.find(params[:id])
end 

It needs params[:id]

So you need to use /articles/id/edit (replace id with your actual id)

ActiveRecord::RecordNotFound in ArticlesController#show - Couldn't find Article with 'id'=13

In your destroy action, change the redirect to articles_path (plural) instead of the singular version. The singular version will attempt to look for the article that you just deleted, which of course no longer exist.

def destroy
    @article = Article.find(params[:id])
    @article.destroy
    redirect_to articles_path # pluralized the path
end

How to solve ActiveRecord::RecordNotFound?

The line is giving you an ActiveRecord::RecordNotFound exception is this one

@article = Article.find(params[:article][:id])

You have no key id in the hash within article.

There is a conflict between the cancancan gem. You need to add a file called cancan.rb in config/initializers with the following

require_dependency 'cancan/model_adapters/active_record_4_adapter'

if defined?(CanCan)
  class Object
    def metaclass
      class << self; self; end
    end
  end

  module CanCan
    module ModelAdapters
      class ActiveRecord4Adapter < ActiveRecordAdapter
        @@friendly_support = {}

        def self.find(model_class, id)
          klass =
              model_class.metaclass.ancestors.include?(ActiveRecord::Associations::CollectionProxy) ?
                  model_class.klass : model_class
          @@friendly_support[klass]||=klass.metaclass.ancestors.include?(FriendlyId)
          @@friendly_support[klass] == true ? model_class.friendly.find(id) : model_class.find(id)
        end
      end
    end
  end
end
