Issue creating a User through an Account model Rails 5 with Devise - ruby-on-rails

Question

What I'm trying to accomplish:
When a user registers with my app they are taken to a new account creation page. This is where they enter their desired subdomain. from this form I also want to create the owner (a user class).
The problem:
As it sits right now, when i fill out the generated form (below)
<%= form_for #account do |f| %>
<%= fields_for :owner do |o| %>
<p>
<%= o.label :f_name %>
<%= o.text_field :f_name %>
</p>
<p>
<%= o.label :m_name %>
<%= o.text_field :m_name %>
</p>
<p>
<%= o.label :l_name %>
<%= o.text_field :l_name %>
</p>
<p>
<%= o.label :email %>
<%= o.email_field :email %>
</p>
<p>
<%= o.label :password %>
<%= o.password_field :password %>
</p>
<p>
<%= o.label :password_confirmation %>
<%= o.password_field :password_confirmation %>
</p>
<% end %>
<p>
<%= f.label :subdomain %>
<%= f.text_field :subdomain %>
</p>
<%= f.submit %>
<% end %>
and try to submit the form, I get the following rails server output:
Started POST "/accounts" for 127.0.0.1 at 2018-04-08 21:52:57 -0600
Processing by AccountsController#create as HTML

Rendered accounts/new.html.erb within layouts/application (2.4ms)
Completed 200 OK in 49ms (Views: 21.5ms | ActiveRecord: 8.3ms)
Now when I read the output I cant seem to find why this is rolling back and not saving. I do see it telling me an account already exists whit that subdomain, however this is a CLEAN database and there are no accounts saved in it! When I run byebug just before the #account.save in the accounts controller (below) there are no error messages or details I can find.
My AccountController: (I've left the byebug in the controller, perhaps im putting it in the wrong place?)
class AccountsController < ApplicationController
def index
end
def show
end
def new
#account = Account.new
#account.build_owner
end
def create
#account = Account.new(account_params)
byebug
if #account.save
redirect_to root_path, notice: 'Account creates successfully.'
else
render action: 'new'
end
end
def edit
end
def update
end
def destroy
end
private
def account_params
params.require(:account).permit(:subdomain, :owner_id, :plan_id, :account_verified, :account_status, owner_attributes: [:id, :email, :password, :password_confirmation, :f_name, :m_name, :l_name, :office_country_code, :office_phone_number, :mobile_country_code, :mobile_phone_number])
end
end
My Account model
class Account < ApplicationRecord
RESTRICTED_SUBDOMAINS = %w(www admin loadlead)
belongs_to :owner, class_name: 'User'
has_many :users
validates :owner, presence: true
validates :subdomain, presence: true,
#uniqueness: { case_sensitive: false },
format: { with: /\A[\w\-]+\Z/i, message: 'contains invalid characters'},
exclusion: { in: RESTRICTED_SUBDOMAINS, message: 'restricted name'}
before_validation :downcase_subdomain
accepts_nested_attributes_for :owner
protected
def downcase_subdomain
self.subdomain = subdomain.try(:downcase)
end
end
My User model
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :confirmable
belongs_to :account
end
Any assistance here would be greatly appreciated! I have no idea where I'm going wrong with this? Thanks in advance.

Answer 1

Try to call fields_for on f builder instead:
<%= form_for #account do |f| %>
<%= f.fields_for :owner do |o| %>
<p>
<%= o.label :f_name %>
<%= o.text_field :f_name %>
</p>
# ....
<% end %>
# ....
<%= f.submit %>
<% end %>
And you can remove :owner_id, this attribute value will be set automatically by Rails when we're using :accepts_nested_attributes_for.

You are calling #account.save which does not raise an exception. It returns true if everything is fine, or returns false when the validation fails (if #account.valid? returns false).
If there are any validation errors, you can check them by calling:
pry(main)> #account.valid?
pry(main)> false
pry(main)> #account.errors
That should help you debug the issue.
