I'm following the 'Authentication from scratch' railscast but cannot get it to work.
Controller:
class UsersController < ApplicationController
def new
#user = User.new
end
def create
#user = User.new(params[:user])
if #user.save
redirect_to products_path, notice: 'User created successfully'
else
render 'new'
end
end
end
Model:
class User < ActiveRecord::Base
has_secure_password
attr_accessible :email, :password, :password_confirmation
validates_uniqueness_of :email
end
users#new form:
<h1>Sign up form</h1>
<%= form_for #user do |f| %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= f.label :password %>
<%= f.password_field :password %>
<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation %>
<%= f.submit %>
<% end %>
When I try to go to the new user form it throws up a NoMethodError - undefined method 'email' referring to the line that has 'f.text_field :email'.
What am I missing here?
Thanks any help appreciated.
Your users table does not have an email column. Please run a migration to add the column to your users table.

I'm new to RoR and I'm trying to create a sign-up form. When I click on 'Create my account', data does not get saved to the database. I have added resources: users to my routes file. Is there something else I'm missing?
This is my view (signup.html.erb)
Sign Up
<%= form_for #user, :url => { :action => "create" } do |f| %>
<%= f.label :emp_id,"Employee ID" %><br>
<%= f.text_field :emp_id, class: 'form-control' %><br><br>
<%= f.label :password, "Password" %><br>
<%= f.password_field :password, class: 'form-control' %><br><br>
<%= f.label :password_confirmation, "Password Confirmation" %><br>
<%= f.password_field :password_confirmation, class: 'form-control' %><br><br>
<%= f.submit "Create my account", class: "btn btn-primary" %>
<% end %>
This is my controller
class UsersController < ApplicationController
def new
#user = User.new
end
def signup
#user = User.new
end
def show
#user = User.find(params[:id])
end
def create
#user = User.new(user_params)
if #user.save
render 'login'
else
render 'signup'
end
end
def user_params
params.require(:user).permit(:emp_id, :password)
end
end
You need to permit :password_confirmation
def user_params
params.require(:user).permit(:emp_id, :password, :password_confirmation)
end
And make sure there are no other validations like email presence or that will cause validations to fail
I've seen a lot of posts about how to map 2 form fields to one model field, but what about mapping 1 form field to provide answers for two (or more) model fields? I have a form for users which gives a field, last_name, for a user. But I want the default password for that user to also be last_name (and I have password_confirmation set up, so that also needs to be last_name). How would I do this?
Form:
<div class="row">
<div class="col-md-6 col-md-offset-3">
<%= form_for(#user) do |f| %>
<%= f.label :first_name %>
<%= f.text_field :first_name, class: 'form-control' %>
<%= f.label :last_name %>
<%= f.text_field :last_name, :password, :password_confirmation,
class: 'form-control' %>
<%= f.label :email %>
<%= f.email_field :email, class: 'form-control' %>
<%= f.hidden_field :access_level, :value => "Chair" %>
<%= f.label :Phone %>
<%= f.text_field :phone_number, :id => "phone", class: 'form-control' %>
<p> </p>
<div class="col-md-12">
<%= f.submit "Add Chair", class: "btn btn-primary" %>
</div>
<% end %>
</div>
</div>
user_controller.rb
def create
#user = User.new(user_params)
if #user.save
log_in #user
current_user
flash[:success] = "Welcome to the Penn Model Congress!"
redirect_to after_sign_in_path
else
render 'new'
end
end
private
def user_params
params.require(:user).permit(:first_name, :last_name, :email, :password,
:password_confirmation, :access_level,
:phone_number)
end
end
I would add a before_validation callback to the User model like this:
# in app/models/user.rb
before_validation :set_default_password
private
def set_default_password
self.password ||= last_name
self.password_confirmation ||= last_name
end
If this will be your default and you don't want the user to be able to override it on creation, you could set it on the controller:
View:
<%= f.text_field :last_name, class: 'form-control' %>
Controller:
def create
#user = User.new(user_params)
#user.password = #user.last_name
#user.password_confirmation = #user.last_name
if #user.save
log_in #user
current_user
flash[:success] = "Welcome to the Penn Model Congress!"
redirect_to after_sign_in_path
else
render 'new'
end
end
I'm trying to setup a user sign-up system, and when I input an email and password, After pressing submit I always get the same errors: password can't be black, email can't be blank. I am a ruby newbie and have a hard time wrapping my head around parameters setting. If anyone can spot what I did wrong and point it out please do so. I would also be grateful for any documentation and explanations on what I did wrong.
I'm using rails 4.2.1 and ruby 2.2.1p85
Thanks

You need to use user_params correctly. params[:user_params] will return nil.
Your create action should looks like:
def create
#user = User.new(user_params)
...
...
end
params[:user_params] is nil, use #user = User.new(user_params) instead
i'm new in Ruby on Rails.
I was trying to register a new user with devise and at the same time, create a new Company object. The association between them : User belongs to Company. Company has many users. I tried to make it based on this link : http://railscasts.com/episodes/196-nested-model-form-part-1?view=asciicast, but it didnt work. it said : "undefined method for Company", which is Company doesnt have email attribute.
and in sign up form, i only put email attribute for user
<div class="title"><%= t('.signup') %></div>
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="control-group"><%= f.label :email, t('.email') %>
<%= f.email_field :email %></div>
<div class="control-group"><%= f.label :password, t('.password') %>
<%= f.password_field :password %></div>
<div class="control-group"><%= f.label :password_confirmation, t('.password_confirmation') %>
<%= f.password_field :password_confirmation %></div>
<%= f.fields_for :company_attributes do |f_company| %>
<div class="control-group"><%= f_company.label :name, t('.company_name') %>
<%= f_company.text_field :name %></div>
<% end %>
<div class="buttons"><%= f.submit t('.signup'), class:"btn btn-primary" %><br>
<%= render "links" %></div>
<% end %>

Company controller :
class CompaniesController < Devise::RegistrationsController
def new
#company = Company.new
#user = #company.users.build
end
def create
#company = Company.new(params[:company])
#user = User.create(params[:user].merge(company_id:company.id))
if #company.save
redirect_to "/"
else
render 'users/sign_up'
end
end
end
User Controller :
def new
#user = User.new
end
def create
#user = User.new(params[:user])
if #user.save
redirect_to users_path
else
render 'users/new'
end
end
I would really appreciate any idea and any help. Thanks in advance
In your case, since you are only interested in receiving the company_name I'd simplify it and submit the company_name via a text_field_tag.
In other words, I would replace:
<%= f.fields_for :company_attributes do |f_company| %>
<div class="control-group"><%= f_company.label :name, t('.company_name') %>
<%= f_company.text_field :name %></div>
<% end %>
With this
<%= text_field_tag 'company_name', {placeholder:"Enter here the name of your company",class:"form-control"} %>
This would submit the name to the UsersController, and you could access it with params[:company_name] so the controller would look like this:
Users controller:
def new
#user = User.new
end
def create
#user = User.create(params[:user])
#Create a company via 'user<->company' association using 'company_name'
#company= #user.company.create(name: params[:company_name])
if #user.save
redirect_to users_path
else
render 'users/new'
end
end
I have following code trying to create a new User with an associated new Shop resource. However, while the user data is saved correctly, no record for the shop is created. What is wrong?
Users controller:
class UsersController < ApplicationController
def new
#user = User.new
#user.shops.build
end
def create
#user = User.new(user_params)
if #user.save
flash[:success] = "Signed up successfully."
redirect_to root_path
else
flash[:danger] = "Signup failed!"
render 'new'
end
end
private
def user_params
params.require(:user).permit(:email, :password, :password_confirmation,
shop_attributes: [:name])
end
end
User model:
class User < ActiveRecord::Base
has_many :shops
accepts_nested_attributes_for :shops
end
Shop model:
class Shop < ActiveRecord::Base
belongs_to :user
end
Form:
<%= form_for(#user) do |f| %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= f.label :password %>
<%= f.password_field :password %>
<%= f.label :password_confirmation, "Confirmation" %>
<%= f.password_field :password_confirmation %>
<%= f.fields_for :shop do |shop| %>
<%= shop.label :name %>
<%= shop.text_field :name %>
<% end %>
<%= f.submit "Create my account" %>
<% end %>
Check your singular/plural wording (shop_attributes, f.fields_for :shop):
def user_params
params.require(:user).permit(:email, :password, :password_confirmation,
shops_attributes: [:name])
end
and:
<%= f.fields_for :shops do |shop| %>
