I have a little project management app.
In the app I have a Project, Item and Delivery Model.
class Project < ApplicationRecord
has_many :locations, dependent: :destroy
has_many :items, dependent: :destroy
has_many :deliveries, dependent: :destroy
end
class Item < ApplicationRecord
belongs_to :project
belongs_to :location, optional: true
has_many :delivery_items, dependent: :destroy
has_many :deliveries, through: :delivery_items
enum status: [:unscheduled, :scheduled, :delivered]
end
class Delivery < ApplicationRecord
belongs_to :project
has_many :delivery_items, dependent: :destroy
has_many :items, through: :delivery_items
enum status: [ :unapproved, :approved, :scheduled ]
end
I also have a delivery_item join table
class DeliveryItem < ApplicationRecord
belongs_to :delivery
belongs_to :item
end
I have added a new Model called location, which is a way of classifying the items into a group on the project.
class Location < ApplicationRecord
belongs_to :project
has_many :items
has_many :part_numbers, through: :items
def bulkadd(delivery)
self.items.each do |row|
batch << Product.new(row)
end
end
end
At the moment the user individually adds items to deliveries via a form on the page
<h6>Add to Delivery</h6>
<%= form_for #delivery_item, html: {class: 'form-inline'} do |form| %>
<div class="form-group">
<%= form.collection_select :delivery_id, #project.deliveries.all, :id, :date, placeholder: 'Add to Delivery', class: 'form-control' %>
</div>
<%= form.hidden_field :item_id, value: item.id %>
<div class="form-group">
<%= form.submit "Add",class: 'btn btn-primary' %>
</div>
<% end %>
I would like to simplify the process by adding a bulk add button to each location which would add all of the associated items to the delivery selected has many items.
I know that I will need the delivery_item(delivery, item).
I just cant seem to get the final part to work in my brain
When you create a has_many or has_and_belongs_to_many assocation the macro creates an others_ids setter/getter. In this case item_ids= which will automatically add/remove rows from the join table.
Its really easy to use this together with the form option helpers to create a select where the user can choose multiple records:
<%= form_for(#delivery) do |form| %>
<div class="field">
<%= f.label :item_ids, 'Select the items' %>
<%= f.collection_select :item_ids, #items, :id, :name, multiple: true %>
</div>
<% end %>
Or if you prefer checkboxes:
<%= form_for(#delivery) do |form| %>
<div class="field">
<%= f.label :item_ids, 'Select the items' %>
<%= f.collection_check_boxes :item_ids, #items, :id, :name %>
</div>
<% end %>
Replace :name with whatever attribute you want to use for the option text.
class DeliveriesController < ApplicationController
before_action :set_delivery, only: [:show, :edit, :update, :destroy]
# This avoids a database query in the view
before_action :set_items, only: [:new, :edit]
# POST /deliveries
def create
#delivery = Delivery.new(delivery_params)
if #delivery.save
redirect_to #delivery, notice: 'Delivery created'
else
set_items
render :new
end
end
# PUT|PATCH /deliveries/1
def update
if #delivery.update(delivery_params)
redirect_to #delivery, notice: 'Delivery updated'
else
set_items
render :edit
end
end
private
def set_delivery
#delivery = Delivery.find(params[:id])
end
def set_items
#items = Item.all
end
def delivery_item_params
# Passing the hash `item_ids: []` allows an array of permitted scalar types.
params.require(:delivery)
.permit(:foo, :bar, :baz, item_ids: [])
end
end
any help would be most appreciated, I am rather new to Rails.
I have two models a Shopping List and a Product. I'd like to save/update multiple products to a shopping list at a time.
The suggested changes are not updating the models. I've been googling and is "attr_accessor" or find_or_create_by the answer(s)?
Attempt 1 - Existing code
Error
> unknown attribute 'products_attributes' for Product.
Request
Parameters:
{"_method"=>"patch",
"authenticity_token"=>"3BgTQth38d5ykd3EHiuV1hkUqBZaTmedaJai3p9AR1N2bPlHraVANaxxe5lQYaVcWNoydA3Hb3ooMZxx15YnOQ==",

"7"=>{"title"=>""},
"8"=>{"title"=>""},
"9"=>{"title"=>""},
"10"=>{"title"=>""}}},
"commit"=>"Save Products",
"id"=>"7"}
Attempt 2 - no errors the page reloads and none of the expected fields are updated. In earnest, I am Googling around and copying and pasting code snippets in the vain hope of unlocking the right combo.
Added to Products mode
class Product < ApplicationRecord
attr_accessor :products_attributes
belongs_to :list, optional: true
end
<%= content_tag(:h1, 'Add Products To This List') %>
<%= form_for(#list) do |f| %>
<%= f.fields_for :products do |pf| %>
<%= pf.text_field :title %><br>
<% end %>
<p>
<%= submit_tag "Save Products" %>
</p>
<% end %>
<%= link_to "Back To List", lists_path %>
list controller
def update
#render plain: params[:list].inspect
#list = List.find(params[:id])
if #list.products.update(params.require(:list).permit(:id, products_attributes: [:id, :title]))
redirect_to list_path(#list)
else
render 'show'
end
list model
class List < ApplicationRecord
has_many :products
accepts_nested_attributes_for :products
end
original do nothing - product model
class Product < ApplicationRecord
belongs_to :list, optional: true
end
If you just want a user to be able to select products and place them on a list you want a many to many association:
class List < ApplicationRecord
has_many :list_items
has_many :products, through: :list_products
end
class ListItem < ApplicationRecord
belongs_to :list
belongs_to :product
end
class Product < ApplicationRecord
has_many :list_items
has_many :lists, through: :list_products
end
This avoids creating vast numbers of duplicates on the products table and is known as normalization.
You can then select existing products by simply using a select:
<%= form_for(#list) do |f| %>
<%= f.label :product_ids %>
<%= f.collection_select(:product_ids, Product.all, :name, :id) %>
# ...
<% end %>
Note that this has nothing to with nested routes or nested attributes. Its just a select that uses the product_ids setter that's created by the association. This form will still submit to /lists or /lists/:id
You can whitelist an array of ids by:
def list_params
params.require(:list)
.permit(:foo, :bar, product_ids: [])
end
To add create/update/delete a bunch of nested records in one form you can use accepts_nested_attributes_for together with fields_for:
class List < ApplicationRecord
has_many :list_items
has_many :products, through: :list_products
accepts_nested_attributes_for :products
end
<%= form_for(#list) do |f| %>
<%= form.fields_for :products do |pf| %>
<%= pf.label :title %><br>
<%= pf.text_field :title %>
<% end %>
# ...
<% end %>
Of course fields_for won't show anything if you don't seed the association with records. That's where that loop that you completely misplaced comes in.
class ListsController < ApplicationController
# ...
def new
#list = List.new
5.times { #list.products.new } # seeds the form
end
def edit
#list = List.find(params[:id])
5.times { #list.products.new } # seeds the form
end
# ...
def update
#list = List.find(params[:id])
if #list.update(list_params)
redirect_to #list
else
render :new
end
end
private
def list_params
params.require(:list)
.permit(
:foo, :bar,
product_ids: [],
products_attrbutes: [ :title ]
)
end
end

I have two models:
user.rb
class User < ActiveRecord::Base
...
has_many :reports, :foreign_key => "assigned_user_id"
...
end
report.rb
class Report < ActiveRecord::Base
belongs_to :assigned_user, :class_name => "User"
end
index action
def index
#all_reports = Report.all
end
index.html.erb
<% #all_reports.each do |report| %>
<%= report.user.email %> </br>
<% end %>
This throws me the error:
undefined method `user' for #<Report:0x007f90dc642e80>
What am I missing? My other - standard rails - associations work perfectly.
Change this line:
<%= report.user.email %> </br>
To:
<%= report.assigned_user.email %> </br>
I'm trying to associate a relation betwen 1 patient with a consultation, but I'm getting a error:
Association :patient not found
In the model I have:
class Patient < ActiveRecord::Base
belongs_to :user
has_many :consultums, through: :patients
end
class Consultum < ActiveRecord::Base
belongs_to :patients
belongs_to :user
has_one :recetum
end
in the controller I have:
class ConsultationController < ApplicationController
before_action :authenticate_user!
before_action :set_consultum, only: [:show, :edit, :update, :destroy]
respond_to :html
def index
#consultation = Consultum.all
respond_with(#consultation)
end
def show
respond_with(#consultum)
end
## when I try to create a new consultation, throw me the error ##
def new
#consultum = Consultum.new
# patient_id
respond_with(#consultum)
end
def edit
end
def create
#consultum = Consultum.new(consultum_params)
#consultum.save
respond_with(#consultum)
end
def update
#consultum.update(consultum_params)
respond_with(#consultum)
end
def destroy
#consultum.destroy
respond_with(#consultum)
end
# def patient_id
# patient = Patient.find(params[:id])
# # patient = #patient.id
# #consultum.patient_id = patient
# end
private
def set_consultum
#consultum = Consultum.find(params[:id])
end
def consultum_params
params.require(:consultum).permit(:Reason_Consultation, :Diagnostic, :TX, :Labs, :Observations, :patient_id)
end
end
so, as you can see I create the function patient_id, and I'm trying to retrieve the id from the 'patient' and put into patient_id in 'consultum' table, but seems not work...
if I uncomment patient_id function throw me this error:
Couldn't find Patient without an ID
I'm stuck, any idea?
Thanks in advance
EDIT
in my view I have:
consultation/new.html.erb
<div class="page-header">
<%= link_to consultation_path, class: 'btn btn-default' do %>
<span class="glyphicon glyphicon-list-alt"></span>
Back
<% end %>
<h1>New consultum</h1>
</div>
<%= render 'form' %>
_form.html.erb
<%= simple_form_for(#consultum) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :Reason_Consultation %>
<%= f.input :Diagnostic %>
<%= f.input :TX, placeholder: "optional" %>
<%= f.input :Labs, placeholder: "optional" %>
<%= f.input :Observations, placeholder: "optional" %>
<%= f.association :patient %>
</div>
<div class="form-actions">
<%= f.button :submit, "Save Consultation" %>
</div>
<% end %>
When creating associations in rails pay super close attention to the pluralization!
class Patient < ActiveRecord::Base
belongs_to :user
has_many :consultums, through: :patients
end
class Consultum < ActiveRecord::Base
belongs_to :patients
belongs_to :user
has_one :recetum
end
You will notice that your Consultum class does not have a patient relation. It has belongs_to :patients.
class Consultum < ActiveRecord::Base
belongs_to :patient
belongs_to :user
has_one :recetum
end
Also your attribute naming should follow the Ruby conventions!
Ruby uses snake_case for naming attributes and methods and will automatically treat any identifier which begins with an UPPERCASE letter as a constant!
This is not just a stylistic issue - MRI Ruby will let you reassign constants with a warning. Other versions or future versions may be less lenient.
Bad Good
.Reason_Consultation .reason_consultation
.Diagnostic .diagnostic
.TX .tx
.Lab .lab
.Observations .observations
https://github.com/bbatsov/ruby-style-guide
To call an action you can pass parameters as follow:
link_to "New Consultum", new_consultum_path(:id => here, yo have to put the paciente id)
Hope this helps!
When i try to submit the form below i get this error WARNING: Can't mass-assign protected attributes: sub_category.I have tried to go over previous asked related questions here on stackoverflow and seems like i am in the right track ,but for some reason i am still getting the same error,what am i doing wrong?.I have included all the info below, thank you in advance.
View/form
<%= form_for #ip ,:url=>{:action =>"create"} do |f| %>
<%=f.text_field :email %>
<% f.text_field :ip_address %>
<%= f.fields_for :sub_category do |s| %>
<%=s.text_field :name%>
<%end%>
<%=f.submit "submit" %>
<%end%>
Controller
def create
#ips=Ip.new(params[:ip])
#ip=#ips.sub_categories.build
if #ip.save
redirect_to :controller=>"home" ,:action=>"index"
else
render 'index'
end
Models
class Ip < ActiveRecord::Base
has_many :sub_categories ,:through=>:ip_subs
has_many :ip_subs
accepts_nested_attributes_for :sub_categories
attr_accessible :sub_categories_attributes,:ip_address,:email,:ip_count
end
class SubCategory < ActiveRecord::Base
has_many :ip ,:through=>:ip_subs
has_many :ip_subs
end
class IpSub < ActiveRecord::Base
belongs_to :ip
belongs_to :sub_category
end
You should use f.fields_for :sub_categories (association name).
And don't forget to build association before render the form:
# in controller
def new
#ip = Ip.new
#ip.sub_categories.build
end
