i am new to rails so any help would be much appreciated. I have the models userrs (recruiters) and adverts. Userr has_many adverts and Advert belongs to a user.
Question: when a userr creates an advert i want the created advert to
be automatically linked to the userr that created the advert. I am
unsure how to go about this in the controller
i know how to assign an advert to a user in the console. but unsure how to do this in the controller
console
advert = Advert.first
advert.userr_id = 3
advert.save
route
Rails.application.routes.draw do
resources :adverts
resources :feedbacks
devise_for :userrs
devise_for :userjs
root 'static_pages#homepg'
get 'affiliate', to: 'static_pages#affiliatepg'
get 'terms', to: 'static_pages#termpg'
get 'privacy', to: 'static_pages#privacypg'
get 'contact', to: 'static_pages#contactpg'
get 'about', to: 'static_pages#aboutpg'
get 'recruiters', to: 'static_pages#recruiterpg'
get 'jobseekers', to: 'static_pages#jobseekerpg'

get 'news', to: 'static_pages#newspg'
get 'offer', to: 'static_pages#offerpg'
get 'refferal', to: 'static_pages#refferalpg'
end
i placed the below code:
in my advert controller under the create function:
def create
#userr = Userr.find(params[:userr_id])
#advert = #userr.adverts.build(params[:advert])
if #advert.save
flash[:notice] = 'Successfully created advert'
redirect_to recruiters_path
else
render action: 'new'
end
end
but i got the error:
Couldn't find Userr without an ID

any help will be appreciated
First, you need to add userr_id to params:
def advert_params
params.require(:advert).permit(:userr_id, :title, :content, :category_jobtype_id, :category_positiontype_id, :salarystart, :salaryend, :category_country_id, :city, :town, :postcode, :category_editorialapproval_id, :category_applicationrequest_id)
end
Second, add userr_id to the form:
<%= simple_form_for(#advert) do |f| %>
<%= f.hidden_field(:userr_id) %>
Third, change the param name in create:
def create
#userr = Userr.find(params[:advert][:userr_id])
You can do the same via routes, without altering the form. It's much cleaner but needs more source changes. I can't give you the full syntax here, but it will look like the following:
#routes.rb
resources :userrs do
resources :addverts
end
And the advert's form will become /userrs/[user-id]/adverts, so you'll be able to get the user id from the url instead of the form field. But you'll need to change all the path shortcuts.

I'm a rails noob that's tryin to do something in his app.
My problem is:
I have a Corso model, a Libro model and an Annuncio model. Corso has_many Libro, Libro has_many Annuncio, Annuncio belongs_to Libro and Libro belongs_to Corso. I want a form where the user can create a Libro (that MUST be associated to a Corso) and meanwhile an Annuncio of that Libro must be created. I'm literally freaking out, I saw hundreds of discussions but nothing solved my problem. Every time I change something I get some different errors.
My focus is:
- how to pass the corso_id (I mean, the objects Corso are already defined in the db) to the new Libro when I submit the form;
-I don't see why a Libro object is created (all fields nil) but an Annuncio object doesn't. It seems like the code #libro.annuncios.build in LibroController/new is useless.
I hope you will help me to get this form working.
LibroController:
class LibroController < ApplicationController
def new
#corso = Corso.find(params[:corso_id])
#libro = #corso.libros.build
#libro.annuncios.build
end
def create
#corso = Corso.find(params[:corso_id])
#libro = #corso.libros.build(libro_params)
if #libro.save
redirect_to #libro
else
redirect_to root_path
end
end
def show
#libro = Libro.find(params[:id])
end
def index
end
private
def libro_params
params.require(:libro).permit(:titolo, :autori, :casa_editrice, :edizione, :anno_pubblicazione, :ISBN, :immagine, :corso_id, annuncios_attributes[:prezzo, :note])
end
end
AnnuncioController:
class AnnuncioController < ApplicationController
def new
#annuncio = Annuncio.new
end
def create
#libro = Libro.find(params[:libro_id])
#annuncio = #libro.annuncio.build(annuncio_params)

EDIT: edited with #arieljuod advices
You don't need to merge the corso_id here: #libro = #corso.libros.build(libro_params.merge({corso_id: #corso.id})). ActiveRecord already sets the corso_id since you are doing #corso.libros.build(...).
You also don't need that hidden_field with the Corso id since you already have that from the URL.
You may want to do #libro = #corso.libros.build on your new action too.
And finally, I think this is the main problem: this is wrong belongs_to :corso, inverse_of: :corsos, it should be inverse_of: :libros
Fix the other things I point out too to clean up your code.
EDIT:
to add a select do something like this:
= libro.select :corso_id, options_from_collection_for_select(Corso.all, :id, :name)
I'm trying to increment new values to an array but the old values get deleted. As you can see in the following, I had one image there and now its NULL, but the new image is there.
SQL (1.5ms) UPDATE "attachments" SET "media_files" = $1, "updated_at" = $2 WHERE "attachments"."id" = $3 [["media_files", "{NULL,image4.jpg}"], ["updated_at", "2018-10-25 09:12:05.564281"], ["id", 11]]
I'm using the carrierwave gem and this is the method I have inside the controller in order to keep the existing values and increment the new ones:
def create
files = #attachment.media_files # copy the old images
files += params[:item][:media_files] # add new file to the files
#attachment.assign_attributes(:media_files => files) # assign back
if #attachment.save
flash[:notice] = "Media files where successfully uploaded"
redirect_back fallback_location: root_path
else
flash[:alert] = "Failed to upload media files"
redirect_back fallback_location: root_path
end
end
And the form is:
<%= form_for #item, url: create_image_path(#attachment), method: :post , :html => {:id => "form"} do |f| %>
<%= f.file_field :media_files, multiple: true %>
<%= f.submit 'Add' %>
<% end %>
Models associations:
class Item < ApplicationRecord
has_many :attachments, dependent: :destroy
accepts_nested_attributes_for :attachments, allow_destroy: true
end
class Attachment < ApplicationRecord
belongs_to :item
mount_uploaders :media_files, AttachmentUploader
validates_presence_of :media_files
end
The schema for the two models:
create_table "attachments", force: :cascade do |t|
t.integer "item_id"
t.integer "account_id"
t.string "media_files", default: [], array: true
t.string "content_type"
t.boolean "success"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "items", force: :cascade do |t|
t.string "title"
t.string "description"
t.integer "category_id"
t.integer "account_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
The route for the create method:
post "item/:id/uploads/media_files/:id"=> "attachments#create", :as => :create_image
Any idea what I might be missing here?
You can go with your own code the modification need to done is: -
def create
exitsting_files = #attachment.media_files # copy the old images
new_file = params[:item][:media_files] # new file to the files
new_attachment = Aattachment.new(:media_files => new_file, id: #item.id) #New attachment submitted by form
if new_attachment.save
#push back your exitsting_files along with new one
#attachment.media_files.push(exitsting_files)
#attachment.save
flash[:notice] = "Media files where successfully uploaded"
redirect_back fallback_location: root_path
else
flash[:alert] = "Failed to upload media files"
redirect_back fallback_location: root_path
end
end
However this should be done with nested_atrributes_for concept
<%= form_for #item, url: create_image_path(#attachment), method: :post , :html => {:id => "form"} do |f| %>
<%= f.fields_for : attachments do |ff| %>
<%= ff.file_field :media_files, multiple: true %>
<%end%>
<%= f.submit 'Add' %>
<% end %>
And so on... you can get lots of example for nested form

Here is my list model:
class List < ApplicationRecord

How can I solve this?
You are having logic problem with your model association.
Assuming that a List could have more than one Item, you shouldn't have declared your table List with the attribute item_id. (Doing that it means a List could ONLY have one item). I recommend you read ruby-on-rais-guide-for-associations.
For the problem with the user_id, you need to explicit declared the user_id in your list object (considering that you want to associate a List with a User in the moment the List is created). One way to do it could be:
def create
#list = List.new(list_params)
#list[:user_id] = current_user.id # Considering you add this method
if #list.save
redirect_to home_url
else
render :new
end
And add some validation in model:
class List < ApplicationRecord
has_many :items
belongs_to :user
validates :user_id, presence: true
end
It seems you need to read more about validation too ruby-on-rais-guide-for-validation. About your twice rollback, it is unclear the reason, but fixing you association and validations problems, I think you can fix it.
Try read more about rails, the problem you are having are really basic. Good luck!
UPDATE:
As suggested by at0misk answer, to solve the problem with twice rollback:
In List controller:
#list = List.new(list_params)
# instead of #list = List.create(list_params)
The create method create a new object and save immediately. So, rails was trying to save twice, in the method create first, then in the method save in sequence.
In your create method, you're calling create and then calling save. Create creates an object and saves it to the database, so calling save is redundent.
Have you checked to see if your record is saving? If it is then this is definitely what's wrong. I prefer to use this pattern, using new instead of create, and then attempting to save in an if block:
def create
#list = List.new(list_params)
if #list.save
redirect_to home_url
else
render :new
end
end
When I submit the form, the data is not being sent in the post and set via parameters. I can't for the life of me figure out why. This form is in the plan/show action, so that's why you see me setting the #action variable there. It is sent via JS.
routes.rb
resources :plans do
resources :actions
end
action.rb
belongs_to :plan
plan.rb
has_many :actions
plans_controller.rb
def show
#plan = current_user.plans.includes(:actions).find(params[:id])
#action = Action.new
respond_to do |format|
format.html # show.html.erb
format.json { render json: #plan }
end
end
actions_controller.rb
before_filter :get_plan
def create
#action = #plan.actions.new(params[:action])
#action.user_id = current_user.id
#action.save
end
private
def get_plan
#plan = current_user.plans.find(params[:plan_id])
end
create.js.erb in views/actions folder
$('div#actions').prepend("<%= escape_javascript(render #action) %>");
$('div#<%= dom_id(#action) %>').effect('highlight');
_form.html.erb partial
<%= form_for ([#plan, #action]), remote: true do |f| %>
<%= f.text_field :desc %>
<%= f.number_field :days %>
<%= f.submit %>
<% end %>
parameters sent via POST (missing action hash - why??)

Action is a reserved word. If you call it anything else (except controller, which is also reserved) then it will work.
http://guides.rubyonrails.org/action_controller_overview.html#routing-parameters
The params hash will always contain the :controller and :action keys, but you should use the methods controller_name and action_name instead to access these values.
