PostsController Update Method Not Working

[helloamandamurphy]

Current code:

def update
	  @post = Post.find(params[:id])
	  @post.update(params.require(:post))
	  redirect_to post_path(@post)
	end

It gives me this error:

 1) form shows an update form that submits content and redirects and prints out params
     Failure/Error: @post.update(params.require(:post))
     
     ActiveModel::ForbiddenAttributesError:
       ActiveModel::ForbiddenAttributesError

What worked for me:

	def update
	  @post = Post.find(params[:id])
	  @post.update(params.require(:post).permit!)
	  redirect_to post_path(@post)
	end

I also don't understand why the routes aren't written in this ReadMe. If it's a ReadMe and it's not teaching routes, they should be written so we can focus on the material being taught. It's distracting.
