First issue of this kind

This was inevitable, my app seems to be working well in my localhost, but when deployed to heroku, it has fallen apart. I write this post after hours of trying to fix it. I have partially fixed it, however, another issue persists. I will take a look at it tomorrow with a fresh head. It has been a long day, frustrating at times, but as I reflect back on my day, it has been well worth the effort.

The error as seen on my heroku console log. Any suggestion so as to what I should be looking for. I can see a fatal, unknown attribute 'user_id' for Post. But, these very code work fine on my localhost. Is it a case of my Post database not getting migrated. I have run db:migrate multiple times, and I really don't know how to go about it any more. Any suggestions, on how I can debug better and find what lines are causing the issue?

What my posts_controller.rb looks like? I can see from the console it points me to the new action in line 22.

lass PostsController < ApplicationController
    skip_before_action :require_valid_user!, only: [:index]



    def index
        @post = Post.all
        if session[:user_id] 
            @user_id = current_user.post.all
        end


    end

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

    def new
        @post = current_user.post.build       
    end

    def create
        post = current_user.post.build(post_params)
        if post.save
            redirect_to post_path(post)           
        else
            flash[:error] =   "could not save"
            redirect_to new_post_path          
        end
    end

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

    def update
        @post = Post.find(params[:id])
        if @post.update(post_params)
            redirect_to @post
          else
            render 'edit'
        end
    end

    def destroy
        @post = Post.find(params[:id])
        @post.destroy
            redirect_to root_path
    end


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



end

Prior to this, I was having an issue with the User model, I sorted that out by removing the user model and running db:migrate again. That seemed to do that trick for the user and I was able to register and login. However, now the issue seems to be on the post model.

Anyway, time for me to sleep on it , and get back at it tomorrow.
