Rails 4.2.1: Cannot create record

Question

today I tried creating a new model like usual I created my controller first:

rails g controller Newsletters

Then I created my model:

rails g model Newsletter

Then I updated my migration:

class CreateNewsletters < ActiveRecord::Migration
  def change
    create_table :newsletters do |t|
      t.string :subject
      t.text :message
      t.string :recipient
      t.boolean :send, default: false

      t.timestamps null: false
    end
  end
end

Finally I ran my migration:

rake db:migrate

I setup my controller:

class NewslettersController < ApplicationController
  def index
    @newsletters = Newsletter.all
  end

  def show
    @newsletter = Newsletter.find_by(id: params[:id])
  end

  def new
    @newletter = Newsletter.new
  end

  def create
    @newletter = Newsletter.new(newsletter_params)
    if @newsletter.save
      flash[:success] = "Newsletter saved"
      redirect_to newletter_path
    else
      render 'new'
    end
  end

  def edit
  end

  def update
  end

  def destroy
    newsletter = Newsletter.find_by(id: params[:id]).destroy
    flash[:success] = "Successfully destroyed"
  end


  private
    def newsletter_params
      params.require(:newsletter).permit(:subject, :message, :recipient, :send)
    end
end

Now here is the problem. When I try to create a record in the console I get this error:

irb(main):001:0> newsletter = Newsletter.create(subject: "test", message: "test test", recipient: "all")
ArgumentError: wrong number of arguments (given 2, expected 0)

What I tried this far:

1. I rolled everything back and removed all files generated and did it all by hand again.
2. I install the bundle again in case something is outdated

I don't really get what the error is so if someone could help me I would appreciate it a lot.

PS: I have read on github that it could be a problem with the "rb-fsevent" gem but my logs dont show the same thing:

https://github.com/guard/listen/issues/431

UPDATE:

My Newsletter model

class Newsletter < ActiveRecord::Base
end

PS: I am running ruby 2.3.0

Answer 1

send is a Ruby method and it leads to problems when you have an attribute with the same name.

Just rename that column to something else - like email_send or was_send and you will be fine.
