can't convert Symbol into String

[Josh Swasey]

Hello,

I'm following the tutorial at http://guides.rubyonrails.org/getting_started.html. 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..
