NoMethodError: undefined method 'id' for #<Array:0x007f725c52af50>

I have two models Blog and Article as follows

class Blog < ActiveRecord::Base
    has_many :articles
end

class Article < ActiveRecord::Base
   belongs_to :blog
end

And my dashboard method is as follows: [I want to fetch all the articles of all the followed blogs in @article object]

@f_blogs = current_user.followees(Blog) #Socialization gem method
@f_blogs.each do |blog|
    @blogs ||= []
    @blogs << Blog.where('id == ?',blog.id).includes(:articles)
end
@articles = @blogs.map(&:articles)

But this returns this error

NoMethodError: undefined method 'id' for #<Array:0x007f725c52af50>

The console gives output in ActiveRecord::Associations::CollectionProxy

How to access this array?? Need help !!

You can refactor this a lot as you can pass an array of id's into a where clause, like so:

@blogs = Blog.where(id: @f_blogs.pluck(:id)).include(:articles)

All together that might just look like this:

@f_blogs = current_user.followees(Blog) #Socialization gem method
@blogs = Blog.where(id: @f_blogs.pluck(:id)).include(:articles)
@articles = @blogs.map(&:articles)

Though I don't totally understand what that last map line is for as you've already eager loaded the articles for each blog.
