Can't convert Symbol into String

Rails
1

Hello,

I’m following the tutorial at
Getting Started with Rails — Ruby on Rails Guides. I got to the point
where adding new posts should be functional (the end of 5.7). When I try
to
submit a post, I receive the error stating “Can’t convert Symbol into
String”. The trace shows:

app/controllers/posts_controller.rb:16:in post_params' app/controllers/posts_controller.rb:6:in create’

This error occurred while loading the following files:
post

The code in my posts_controller.rb file is:
class PostsController < ApplicationController
def new
end
def create
@post = Post.new(params[:post].permit(:title, :text))

@post.save
redirect_to @post
end
def show
@post = Post.find(params[:id])
end
private
def post_params
params.require(:post).permit(:title, :text)
end
end

Can anyone give me any pointers on why this might be happening? Or is
there
any other portion of the application what would be helpful to see for
troubleshooting?

Thanks.

This looks like your code is expecting strong_parameters to be setup
(available as a gem in rails 3.2, turned on by default in 4.0) but your
app
isn’t using strong parameters. Which version of rails are you using ?

change @post = Post.new(params[:post].permit(:title, :text)) to @post =
Post.new(post_params).
you only need use Post.new([methods])
[methods] => define on private methods
thats is your strong parameter works…
