  private

  def post post_params
    params.require(:post).permit(:title, :body)
  end   
end

Answer 1

Here your method name is post and it takes an argument post_params . But in your code you intend to use post_params as the method name.

So change this:

def post post_params
 params.require(:post).permit(:title, :body)
end 

to:

def post_params
 params.require(:post).permit(:title, :body)
end 

Answer 2

You have a type here:

def post post_params
  params.require(:post).permit(:title, :body)
end

Remove post :

def post_params
  params.require(:post).permit(:title, :body)
end
