Build a Simple Ruby on Rails Application - Generating the user model problems --> every time I enter a email and password it says its blank

Noticed a couple of differences from what I put together, try this

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  before_filter :configure_permitted_parameters, if: :devise_controller?

  protected
  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) << [:email, :password] #add or remove parameters as needed
  end
end

Hi, I ran into the same problem here. I'm using rails 4 and had to include the gem 'protected_attributes'.

If I'm now trying to sign up as a new user i got there error:

2 errors prohibited this user from being saved: Email can't be blank Password can't be blank

The error is shown on the page directly and not on a rails error page.

Ricardo De la Fuente: I also tried your code but still get the same error.

Could you by any chance post a copy of your project or link to it's github repository thus far, it's kind of hard to debug without the remaining code as it could be a number of things, in a number of files

--apologies for the duplicate reply, meant to add to the above comment which I cannot, for some reason.. edit

Thanks Ricardo. You can find the code on github.

Alright... so here's the issue I encountered with your version of the project:

I'm guessing your first attempt to fix the issue involved adding the following line to the gemfile:

gem 'protected_attributes'

Since we're using strong parameters (the 4.0 way) with devise, you'll want to remove this gem, as well as the following line from the statuses model (status.rb):

attr_accessible :content, :name

The line above is not necessary as you've already implemented the following within the statuses controller:

def status_params
    params.require(:status).permit(:name, :content)
end

P.S. Remember to (1) re-run bundle at the command line & (2) that the following line:

devise_parameter_sanitizer.for(:sign_up) << [:user_name, :last_name, :first_name]

in the application controller need only include parameters you've personally added to the user model; :email & :password were used as examples in my first post, but these two fields are already accessible to devise via it's "database authenticatable" module.

Cool, works now. Thanks!

Hi all,

I am also having this problem but your solutions don't seem to be working for my files. Any help would be great! The files are here on git hub: https://github.com/Payge/treebook
