ActiveModel::ForbiddenAttributesError while creating a new entry

I am new to Ruby on Rails and I was trying to create a simple app when I ended up having a ActiveModel::ForbiddenAttributesError

class PostsController < ApplicationController
def index
    @posts = Post.all       
end

def show
    @post = Post.find(params[:id])
end

def new
    @post =Post.new
end

def create
    @post = Post.new(params[:post])
    if  @post.save
        redirect_to post_path,:notice=>"success"
    else
        render "new"
    end
end

def edit
end

def update
end

def destroy
end

private
    def post_params
      params.require(:post).permit(:Title, :content)
    end

end

I have seen a similar error here but the solution for that did not fix my issue.

My version of rails is 4.2.0.

The error displayed is

def create
  @post = Post.new(posts_params)
  if  @post.save
    redirect_to post_path,:notice=>"success"
  else
    render "new"
  end
end

private

def posts_params
  params.require(:post).permit(:Title, :content)
end

I think that

def create
  @post = Post.new post_params
  if @post.save
    flash[:success] = "Created new post"
    redirect_to @post
  else
    render 'new'
  end
end

You can't use that params[:post] hash (or any params[*] hash) directly in any mass-assignment method, you need to use a permit call so Rails knows you've checked it and to allow it.

So, change your Post.new to @post = Post.new(post_params)

Change @post = Post.new(params[:post]) to @post = Post.new(post_params).
