NoMethodError in Statuses#new after installing Devise and setting up sign up page

I'm assuming this is for a User model?

Did you create a migration to add the first_name, last_name and profile_name columns to the database?

What do you mean by create a migration? do you mean use the rake db:migrate command?

I have not done the Treebook series so I'm not sure how you created the fields on the User model

When you created the User it would have been something like

rails generate devise User first_name:string last_name:string profile_name:string

Did you use that when you created the model?

Can you copy and paste your migration file from when you created the user table? It would be in the directory like db/migrate/XXXXXXXXXX_create_user.rb

I tried doing that but I cannot run rake db:migrate anymore as i get the error: == AddDeviseToUsers: migrating =============================================== -- change_table(:users) rake aborted! An error has occurred, this and all later migrations canceled:

SQLite3::SQLException: duplicate column name: email: ALTER TABLE "users" ADD "email" varchar(255) DEFAULT '' NOT NULL/Users/sujith/Desktop/Programs/Rails/treebook/db/migrate/20140220055902_add_devise_to_users.rb:5:in block in up' /Users/sujith/Desktop/Programs/Rails/treebook/db/migrate/20140220055902_add_devise_to_users.rb:3:inup' Tasks: TOP => db:migrate (See full trace by running task with --trace)

here is my create_user.rb

What does your statuses controller look like?

here is my statuses controller

class StatusesController < ApplicationController
  before_action :set_status, only: [:show, :edit, :update, :destroy]

  # GET /statuses
  # GET /statuses.json
  def index
    @statuses = Status.all
  end

  # GET /statuses/1
  # GET /statuses/1.json
  def show
  end

  # GET /statuses/new
  def new
    @status = Status.new
  end

  # GET /statuses/1/edit
  def edit
  end

  # POST /statuses
  # POST /statuses.json
  def create
    @status = Status.new(status_params)

    respond_to do |format|
      if @status.save
        format.html { redirect_to @status, notice: 'Status was successfully created.' }
        format.json { render action: 'show', status: :created, location: @status }
      else
        format.html { render action: 'new' }
        format.json { render json: @status.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /statuses/1
  # PATCH/PUT /statuses/1.json
  def update
    respond_to do |format|
      if @status.update(status_params)
        format.html { redirect_to @status, notice: 'Status was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: 'edit' }
        format.json { render json: @status.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /statuses/1
  # DELETE /statuses/1.json
  def destroy
    @status.destroy
    respond_to do |format|
      format.html { redirect_to statuses_url }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_status
      @status = Status.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def status_params
      params.require(:status).permit(:name, :context)
    end
end

So, Sujith I may have confused myself help me understand really quick.

The url you are viewing in the browser is localhost:3000/statuses/new, correct?

But the html.erb form that you have linked on the original post, where is that from? What directory is it in? That looks like it has to do with a user, not a status.

Yes but after running the command you mentioned earlier, I can no longer go to the homepage or run rake db:migrate due to the error

rake aborted!
An error has occurred, this and all later migrations canceled:

Ah Sujith, I'm sorry I didn't want you to run the command. I was asking you if that was the command you ran before. But, to remove that error run this

rm /Users/sujith/Desktop/Programs/Rails/treebook/db/migrate/20140220055902_add_devise_to_users.rb

Then try your rake db:migrate

Thanks that command worked but I am still back to the same error. Everything runs fine but i get the error i first mentioned when i navigate to /users/sign_up. The new code is pushed to git. Sorry, I am kinda new to Rails.

Don't be sorry! I feel bad for sending you down a bad path. This is part of learning :)

I'm forking your repository i'll pull it down 1 minute

I pulled down your repository, the page loads just fine for me

really? I get an error when i open up /users/sign_up. I tried restarting my rails server but it didnt seem to help. Do you have any recommendations for me to try?

I have found the problem!

THANKS SOO MUCH! I guess i was removing the column after I added it. Just out of curiosity where did you learn ROR if you didnt use treehouse. Did you do onemonthrails?

I actually started using rails about 3 years ago. It's what got me into coding :) I love the convention > configuration philosophy, MVC, and ruby is just oh so fun to code! I actually didn't do the rails treehouse courses because I didn't know about them at the time; however, I would have if I did! I am 85% self taught and 15% mentored by someone I greatly respect whom I am lucky to work with.

I use Treehouse because my html, css, design and wordpress skills are not very good :(

But I really enjoy reading the forums and helping people with Ruby and Rails questions when I can!

Sorry it took so long, I felt bad for sending you down a bad route there. But, there are two MAJORLY important lessons from this:

1. ALWAYS use source control. See how easy it was to fix the problem? github is an amazing tool and you should always use it! Heck I even have my wife's homework for her masters degree in source control!

2. NEVER give up! You will get down, you will get frustrated, you will want to bang your head against the desk.. and when that time comes... take a 10 minute break (I play video games to clear my head) then come back to it. Because the solution is always there, it doesn't matter how you find it, but you will find it as long as you don't give up!

I don't want to advertise anything here, but I will recommend this book... I have zero affiliation with the author or publisher... but I learned SO MUCH from this book. It's my favorite Ruby book and I have great respect for the author

Thanks a lot for the pointers, I'll make sure to check out the book after my SAT's. I started off with Java and HTML, so I am familiar with OOP but not so much with Ruby's syntax. Thanks again and have fun with rails!
