Hello I am having a hard time debugging my code. What I need to do is create a page where the user will type in a last name and the system will return information related to it. I am stuck and can not debug it any help or guidance would be greatly appreciated
Model of my Customer table
class Customer < ActiveRecord::Base
has_many :booking
has_many :room, :through => :booking
def mail_list
"#{first} - #{last} - #{maillist}"
end
end
Here is the page that should display the data after the user enters a last name
<center><table width = 65% border = 1>
<tr> <th> Customer Name</th><th> Room Number </th> <th> Cost </th></tr>
<% #customers_list.each do |m| %>
<% p = m.cost %>
<tr> <td> <%= m.name %> </td> <td> <%= m.roomnumber %> </td> <td> <%= m.cost %> </td> </tr>
<% end %> </table> </center><br /> <br />
Here is the page that takes in the last name
<%= form_tag(bookin_bookout_path, :controller => "bookin", :action => "bookout", :method => "post") do %>
<div class="field">
<%= label_tag :Customer_Name %><br />
<%= text_field_tag :customer_name_in %>
</div>
<div class="actions">
<%= submit_tag "Submit Customer Name" %>
</div>
<% end %>
Model of my rates table
class Rate < ActiveRecord::Base
validates :season, :room, :cost, presence: true
has_many :booking
has_many :room, :through => :booking
end
Here is the Controller of my bookin that runs the user putting in last name and posting results
class BookinController < ApplicationController
def bookin
def bookout
#customer_name = params[:customer_name_in]
r = Customer.find_by_last(#customer_name)
#room_list = r.rooms
end
end
end
Here is the Model of my room table
class Room < ActiveRecord::Base
has_many :booking
has_many :customer, :through => :booking
end
Here is the Model of my booking table
belongs_to :room
belongs_to :customer
belongs_to :rate
end
Here is my routes
Hotel::Application.routes.draw do
resources :bookings
get "bookin/bookout"
post "bookin/bookout"
get "listin/listout"
resources :customers
get "manin/manout"
resources :users
get "mailin/mailout"
get "showin/showout"
resources :roomins
get "ratein/rateout"
get "foodin/foodout"
resources :apples
resources :rooms
resources :menus
resources :rates
get "starter/home"
resources :foods
get "bookin/bookname"
post "bookin/bookname"
root 'starter#home'
end
You need to use pluralized model name with has_many, use this
has_many :bookings
has_many :rooms, :through => :bookings
You have not followed rails' convention over configuration in naming your models and controllers

I am having a problem in the eyes when presenting the data.
I have 3 user models, sponsors and pets Result that sponsors in a table join between users and pets that are nan, my problem is in the hour to show all the sponsors of the mascot in sight and achievement but in a wrong way to La time to msotrar the data. I hope you can tell me how to fix it. Thank you.
Index.html.erb
<h1>Sponsors#index</h1>
<table class="table table-bordered table-hover table-striped" id="histories">
<thead>
<tr>
<th>Mascota</th>
<th>Padrinos</th>
<th>Apadrinar</th>
</tr>
</thead>
<tbody>
<% #pets.each do |pet| %>
<tr>
<td><%= pet.name %></td>
<td>
<% #users.each do |user| %>
<% #sponsors.each do |sponsor| %>
<% if user.id == sponsor.user_id and pet.id == sponsor.pet_id %>
<%= user.email%>
<% else %>
<p>No Tengo Padinos =-( </p>
<% end %>
<% end %>
<% end %>
</td>
<td><button>Apadrinar</button></td>
</tr>
<% end %>
</tbody>
</table>
My controller has the three models that I am sending to view.
def index
#sponsors = Sponsor.all
#users = User.all
#pets = Pet.all
end
pet.rb
class Pet < ApplicationRecord
has_many :adoptions
belongs_to :race, required: false
has_many :users, through: :sponsors
end
user.rb
class User < ApplicationRecord
has_many :pets, through: :sponsors
end
sponsor.rb
class Sponsor < ApplicationRecord
belongs_to :user
belongs_to :pet
end
The output that now shows me the attachment in the image.enter image description here
I also wonder if there is a better way to make the query, to show the respective data.
Another thing is how would I do to no longer be able to sponsor pets that I have already given a sponsor?
You are using a through table to join users and pets, but your associations aren't setup properly. For a through model, you have to have_many of the through table along with a has_many: :through association. Your associations should look like this:
class Pet < ApplicationRecord
has_many :adoptions
belongs_to :race, required: false
**has_many :sponsors**
has_many :users, through: :sponsors
end
class User < ApplicationRecord
**has_many :sponsors**
has_many :pets, through: :sponsors
end
Afther working and following diferent recomendations here is my solution.
<% #pets.each do |pet| %>
<tr>
<td> <%= pet.name %></td>
<td>
<% if pet.sponsors.any? %>
<% pet.sponsors.each do |sponsor| %>
| <%= sponsor.user_email %> |
<% end %>
<% else %>
<p>No Tengo Padinos =-( </p>
<% end %>
</td>
<td>
<%= link_to "Apadrinar", {:controller => "sponsors", :action => "new", :mascot => pet.id }%>
</td>
</tr>
<% end %>
I changed also my models.
sponsor.rb
class Sponsor < ApplicationRecord
belongs_to :user
belongs_to :pet
has_many :gifts
delegate :email, to: :user, prefix: true, allow_nil: true
end
user.rb
class User < ApplicationRecord
has_many :sponsors
has_many :pets, through: :sponsors
end
pet.rb
class Pet < ApplicationRecord
has_many :sponsors
has_many :users, through: :sponsors
end
And finally mi index on Controller.
sponsors_controller.rb
def index
# #sponsors = Sponsor.all
# #users = User.all
# #pets = Pet.all
# #pets_no_sponsors = Pet.where.not(id: Sponsor.select("pet_id")).select("id")
#pets = Pet.includes(:sponsors)
end
By making a delegation now I only make a query which sends everything necessary to my index.
I am building an application where a user can find an event and buy a ticket to that event. Here are my files:
tickets/new.html.erb:
<%= form_tag('/ticket/finish') do %>
<% #event.ticket_types.each do |ticket_type| %>
<tr>
<td><%= ticket_type.name %></td>
<td> <%= number_to_currency(ticket_type.price, unit: 'VND ', precision: 0) %></td>
<td> <%= select_tag(:quantity, options_for_select(0..10)) %></td>
</tr>
<br>
<% end %>
<p>
<%= submit_tag 'Purchase Ticket', class: 'btn btn-primary' %>
</p>
<% end %>
tickets_controller.rb:
class TicketsController < ApplicationController
def new
#event = Event.find(params[:event_id])
#ticket = Ticket.new
end
def purchase
end
end
event.rb:
class Event < ActiveRecord::Base
belongs_to :user
belongs_to :venue
belongs_to :category
has_many :ticket_types
validates_associated :ticket_types
validates_presence_of :user
validates_presence_of :name, :extended_html_description, :hero_image_url
# validates_presence_of :venue, :category
validates_uniqueness_of :name,scope: [:venue_id, :starts_at]
def has_ticket_types?
!!self.ticket_types.present?
end
end
ticket_types.rb:
class TicketType < ActiveRecord::Base
belongs_to :event
validates_presence_of :name, :price, :max_quantity
validates_uniqueness_of :name, scope: :event_id
end
routes.rb:
Rails.application.routes.draw do
devise_for :users
root 'events#index'
get '/yourevents', to: 'events#user_events'
resources :events do
resources :tickets
end
get '/ticket/purchase', to: 'tickets#purchase'
get 'ticket/finish', to: 'tickets#finish'
resources :events do
resources :ticket_types
end
resources :venues
end
My goal is I want when user click the 'purchase ticket' button, it will lead them to a page that shows them the ticket types, and the quantity of those ticket types they have just bought. However, I have no idea how can I pass those params in my purchase action since I don't have a ticket model. Could anybody here give me some hint or guide me to the right direction? Thank you in advance.
I have the following models where UserTreatment is essentially a lookup table but it has another field called instance_cost which stores an integer against each relationship.
class User < ActiveRecord::Base
has_many :user_treatments
has_many :users, :through => :user_treatments
end
class UserTreatment < ActiveRecord::Base
attr_accessible :instance_cost
belongs_to :user
belongs_to :treatment
end
class Treatment < ActiveRecord::Base
attr_accessible :name
has_many :user_treatments
has_many :users, :through => :user_treatments
end
So I can do things like this to get the first instance cost for user id 14
1.9.3p429 :181 > User.find(14).user_treatments.first.instance_cost
=> 100
and this to get the name of the treatment
1.9.3p429 :181 > User.find(14).user_treatments.first.treatment.name
=> "Sports Massage"
However I have a problem representing them in a form using simple_form_for
<% simple_form_for #user do |f| %>
# This sucessfully gives us the checkboxes of all treatments and stores them in the UserTreatments table
<%= f.collection_check_boxes(:treatment_ids, Treatment.all, :id, :name) %>
<%= f.fields_for :user_treatments do |pt| %>
<tr>
<td>
<!-- I WANT THE NAME OF THE TREATMENT HERE -->
</td>
<td><span>£</span> <%= pt.input :instance_cost, :as => :string, wrapper: false, label: false %></td>
</tr>
<% end %>
end
There are two things I need to do.
Show the name of the treatment (how do I do express User.user_treatments.treatment.name with simple_form ?)
Set the instance_cost correctly. Its currently not getting set at all.
When you do fields_for for a nested association then you need to add the following in your User model:
accepts_nested_attributes_for :user_treatments
Otherwise, it will not save the information.
And to access the name of the treatment, you could go through the object method of the form creator object, like this:
<%= f.fields_for :user_treatments do |pt| %>
<tr>
<td><%= pt.object.treatment.name %></td>
...
</tr>
<% end %>
I want to create a multiple form for editing scores from a different model.
The main model is a Formrule model that consists of a habtm association with a Scoretype model
and has a habtm association with a Room model.
Both models are used to query a Scores model resulting in a #scores instance. It is for this instance I want to create a form, but the problem is that no field_for are being created. I know that the #scores is populated correctly, but the form does not show up.
This is the form as I have it now
<%= form_tag '/scores/update_scores' do %>
<table>
<tr>...</tr>
<% for score in #scores %>
<% fields_for :scores, score do |score| %>
<tr>
<td>
<%= score.hidden_field(:form_id) %>
<%= score.hidden_field(:team_id) %>
<%= score.hidden_field(:scoretype_id) %>
</td>
<td>
<%= score.number_field :scorevalue %>
</td>
</tr>
<% end %>
<% end %>
</table>
<%= submit_tag 'Update' %>
<% end %>
And these are the Models:
Formrule
class Formrule < ActiveRecord::Base
belongs_to :form
has_and_belongs_to_many :scoretypes
has_and_belongs_to_many :rooms
has_many :teams, :through => :rooms
end
Scoretype
class Scoretype < ActiveRecord::Base
has_many :scores
has_and_belongs_to_many :formrules
end
Room
class Room < ActiveRecord::Base
has_many :teams
has_and_belongs_to_many :formrules
end
Team
class Team < ActiveRecord::Base
has_many :scores
belongs_to :room
belongs_to :group
end
Score
class Score < ActiveRecord::Base
belongs_to :form
belongs_to :team
belongs_to :scoretype
validates_uniqueness_of :id, :scope => [:team, :scoretype]
end
And finally, the used controller (Formrule)
def show
#formrule = Formrule.find(params[:id])
#scoretypes = #formrule.scoretypes.all.collect
#rooms = #formrule.rooms.all.collect
#teams = Team.find(:all, :conditions => {:room_id => #rooms})
#scores = Score.order("team_id").all(:conditions => {:scoretype_id => #scoretypes, :team_id => #teams})
...
end
Why is the form not showing up? any suggestions?
Thank you all in advance!
Try using <%= fields_for ... %> instead of <% fields_for ...%>.
My goal is to display select box for each relation for users and specific project.
All users need to be listed but only project users have some type of relation. Other users have none selected in theirs select box.
I have this model:
class Project < ActiveRecord::Base
belongs_to :company
has_many :tasks, :order => 'state_type_id ASC'
has_many :project_user_relations
has_many :users, :through => :project_user_relations
def t_name
name.camelcase
end
end
class User < ActiveRecord::Base
belongs_to :company
has_many :tasks , :foreign_key => :assigned_user_id
has_many :project_user_relations
has_many :projects, :through => :project_user_relations
def full_name
firstname + ' ' + lastname
end
def relation_to(project)
relation=ProjectUserRelation.find_by_project_id_and_user_id(project.id, id)
relation ||= relation=ProjectUserRelation.new
end
end
class ProjectUserRelation < ActiveRecord::Base
belongs_to :project
belongs_to :user
has_one :project_user_relation_type
end
class ProjectUserRelationType < ActiveRecord::Base
def t_name
I18n.t("app.projects.users.relation.type."+code)
end
end
I want make a form to display all users, with collection_select.
I used code:
def edit_all
#project = Project.find(params[:project_id])
#users = User.all
....
in my controler
routes works ok.
in my view:
<% #users.each do |user| %>
<%= f.fields_for :users, user do |user_fields| %>
<tr class="reference" rel="<%= parent_user_path(user) %>" >
<td class="name"><%= link_to user.full_name, parent_user_path(user) %></td>
<td class="email"><%= mail_to user.email %></td>
<td class="type">
<%= user_fields.fields_for user.relation_to #project do |relation_fields| %>
<%= relation_fields.collection_select :project_user_relation_type, ProjectUserRelationType.all, :id, :t_name, {:include_blank => false, :prompt => t("helpers.select.prompt") } %>
<% end %>
</td>
</tr>
<% end %>
<% end %>
or for test:
<%= f.fields_for :users, #users do |xuser_fields| %>
<% logger.debug "#{self.to_s} xuser_fields = #{xuser_fields.object.inspect} ;" %>
<tr>
<td><%= xuser_fields.text_field :firstname %></td>
<td></td>
<td></td>
<td></td>
</tr>
<% end %>
but notnihng woks right
first one generates wrong name in html:
select id="project_users_project_user_relation_project_user_relation_type" name="project[users][project_user_relation][project_user_relation_type]"
second one generates error:
undefined method `firstname' for # Array:0x4d03658
Can you help me to solve this situation.
PS:sorry for long code :(
SOLUTION (probably - solved by reading RoR sources)
I found sollution i thing.
A method
def name_attributes=(attributes)
# Process the attributes hash
end
in Project model was missing.
It is unbelievable sollution :].
There is also exact syntax after fields_for: :name, #some_collection, where name must be exactly same name as in the beginign of mentioned def in Model.
