I'm using the friendly_id gem to generate slugs.
I have a model like this
class Veterinarian < ApplicationRecord
extend FriendlyId
belongs_to :user
has_one :profile, through: :user
friendly_id :slug_string, use: :slugged
def slug_string
"#{profile.first_name} #{profile.last_name} #{profile.city}"
end
end
And another model like this.
class Profile < ApplicationRecord
include ReadOnlyModel
belongs_to :user
end
ReadOnlyModel looks like this
module ReadOnlyModel
extend ActiveSupport::Concern
included do
attr_readonly(*column_names)
end
def readonly?
true
end
def destroy
raise ActiveRecord::ReadOnlyRecord
end
def delete
raise ActiveRecord::ReadOnlyRecord
end
end
My issue comes when I'm trying to access profile attributes inside of the veterinarian model. profile.first_name, profile.last_name, etc.
When friendly_id tries to update the slug, it throws an error telling me that the profile model is read only, however I'm just accessing an attribute and using it to create a string for friendly_id to use, nothing is changing in the profile model. However I can do Veterinarian.last.slug_string in the console and it outputs correctly with no errors.
I'm testing this by doing Veterinarian.update(slug: nil) to set the slug to nil and trigger friendly_id to update it with the proper slug.
I've been scratching my head for a good hour and haven't been able to figure out what's going on. It's probably something simple that I'm overlooking. Any help would be appreciated.
my above models are wrapped in a Veterinarians module, I removed it in the code examples for readability reasons.

After further digging, it appears that doing user.profile.attribute_name does not trigger the readonly error.

So I am very new to sidekiq and activejob, I know that i dont need to background job a mailer that being sent on an account creation, however I really want to understand how this all works, and the best way to learn is to do...
I have the following Job, Mailer and Controller action set up, however when I create a new account It fails with tis error: (I have posted the entire stack for brevity)

My Job, Mailer and Controller Actions are here:
class WelcomeEmailJob < ApplicationJob
queue_as :default
def perform(account_id)
#account = Account.find(account_id)
WelcomeNotificationMailer.welcome_owner(#account).deliver_now
end
end
class WelcomeNotificationMailer < ApplicationMailer
def welcome_owner(account_id)
account = Account.find(account)
mail to: #account.owner.email, subject: 'Welcome to the PATROLVAULT family!'
end
end
class AccountsController < ApplicationController
def create
#account = Account.new(account_params)
if #account.valid?
Apartment::Tenant.create(#account.subdomain)
Apartment::Tenant.switch!(#account.subdomain)
#account.save
WelcomeEmailJob.perform_now(#account.id)
redirect_to login_url(subdomain: #account.subdomain), :flash => { notice: 'Account created successfully. Please check your email.' }
end
end
end
I have been stuck on this for some time and I am sure its something i just can't see.
Thanks in advance for your assistance! Please let me know if you require more info.
The app is going too fast, in a way. Welcome email job is being called before Account has been persisted to the db. You should move the job to an after_create_commit hook in your model. i.e.:
in your /app/models/account.rb
class Account < ApplicationRecord
after_create_commit :send_welcome_email
...
def send_welcome_email
WelcomeNotificationMailer.welcome_owner(self).deliver_now
end
end
Edit: if you want to make it a background job, as long as your sidekiq is configured correctly (you have a 'mailers' queue), you can call deliver_later instead of deliver_now and that should do the trick
I want to make a presenter for an index action for Event.
here is what it looks like. there will be more methods and things added to the presenter and the view, but right now I just want to get this working:
class EventPresenter
def initialize(events, template)
#events = events
#template = template
end
def h
#template
end
def event_title
h.link_to event.name, event_path(event)
end
end
index.html.erb:
<% present #events do |event_presenter| %> <tr>
<td><%= event_presenter.event_title %></td>
<% end %>
application helper:
module ApplicationHelper
def present(object, klass = nil)
klass ||= "#{object.class}Presenter".constantize
presenter = klass.new(object, self)
yield presenter if block_given?
presenter
end
end
events_controller:
def index
#events = Event.all.map{ |event| EventPresenter.new(event) }
# render json: #events
end
the way it is now, I'm getting the wrong number of arguments (1 for 2) error for the presenter's initialize method. I was trying to see which of the two objects is not getting passed into the initializer by removing either #events or #template, such as:
def initialize(template)
#template = template
end
but, in both cases the app breaks at the klass ||= line of the application_helper with uninitialized constant ArrayPresenter, while it's supposed to be looking for the EventPresenter constant.

You seem to wrap event objects with a presenter by calling present method in a view layer, so doing the same thing in controller looks redundant to me. Moreover, that actually was a line resulting in wrong number of arguments, as you wrapped it with a single argument only. Let's remove it:
# events_controller
def index
#events = Event.all
# we removed redundant EventPresenter.new(event) here
end
Next step is your view template. As long as #events containts an array of elements (you could check the class of object parameter in your present helper method), you get "#{object.class}Presenter".constantize to end with "ArrayPresenter".constantize, and this results in an error as there is no such class as ArrayPresenter. What you could do here to solve this is to iterate an array first:
<% #events.each do |event| %>
<% present event do |event_presenter| %>
Another option could be to iterate a collection inside of your helper method. You might be intrested in some existing solutions like Draper gem to get an idea of how they solve the objects wrapping issues.
I'm getting a wrong number of arguments (given 2, expected 0..1) error when trying to track the model her views.
My Model:
class Codetip < ApplicationRecord
belongs_to :user
is_impressionable
validates :title, presence: true, length: { minimum: 4 }
validates :body, presence: true, length: { minimum: 4 }
validates :user_id, presence: true
extend FriendlyId
friendly_id :name, use: :slugged
end
Codetip controller:
As https://github.com/charlotte-ruby/impressionist suggested on section 4 under usage.
def show
#codetip = Codetip.friendly.find(params[:id])
impressionist(#codetip)
end
My show view:
<%= #codetip.impressionist_count %>
Next to that ive did everything that the wiki suggested: added the gem, bundled, generated the impressions table and migrated it.

Ive figured out what the problem was.
On my show page it should have been <%= #codetip.impressions.count %> instead of <%= #codetip.impressionist_count %>. This topic can be marked as resolved.
update the condition in gems file as app/models/impressionist/impressionable.rb
replace if Rails::VERSION::MAJOR == 4 with if Rails::VERSION::MAJOR >= 4
please refer https://github.com/charlotte-ruby/impressionist/issues/212
I have a rails app that displays the games in an NFL week. So, if the user navigates to: url.com/week/1/ it will display all of the games.
The format is: /week/:id
The controller looks like this:
def show
#week = Week.find(params[:id])
#user = User.first #place holder until current_user is implemented
#games = #week.games
end
When I go to check the page I get:
ActiveRecord::RecordNotFound in WeekController#show
Couldn't find Week with 'id'=
Extracted source (around line #154):
152
153
154
155
156
157
record = s.execute([id], self, connection).first
unless record
raise RecordNotFound, "Couldn't find #{name} with '# {primary_key}'=#{id}"
end
record
rescue RangeError
The id is blank, though I don't understand why, because it's in the parameters:
Request
Parameters:
{"id"=>"4"}
I can verify using the rails console that this record/week should exist, but rails can't find it for some reason... this was working fine and all of a sudden stopped working when I added some validations to another model, but I don't see how they can be related. This is a really simple query.
Any thoughts?

So I am using the latest active_model_serializer and I am trying to use them to send an array on Medium.
I use this to make a query for the Medium: Medium.includes([{comments: :user}, :user]).where(user_id: user_ids)
So the Medium belong to a user, medium has many comments and every comment has a user (owner).
Now here are the corresponding serializers:
Medium:
class MediumSerializer < ActiveModel::Serializer
attributes :id,
:text,
:image_video_file_name,
:image_video_croppable_url,
:image_video_thumb_url,
:image_video_big_url
belongs_to :user
has_many :comments
end
Comment:
class CommentSerializer < ActiveModel::Serializer
attributes :id,
:text,
:user_id,
:medium_id
belongs_to :user
end
User:
class UserSerializer < ActiveModel::Serializer
include Avatar
attributes :id,
:name,
:email,
:role,
:avatar
def avatar
Medium.find(self.current_avatar)[0]
end
#has_one :avatar, serializer: AvatarSerializer
has_many :media, :comments
end
And also I have these functions in my Medium:
def image_video_croppable_url
image_video.url(:croppable)
end
def image_video_thumb_url
image_video.url(:thumb)
end
def image_video_big_url
image_video.url(:big)
end
I use Paperclip gem and I needed these functions to get access to sizes of different medium images. Maybe there is a better way for it also.
So now when I do the query, I use this line to pass the info to browser and let the serializer make it JSON nicely:
respond_with media, each_serializer: MediumSerializer
But it gives me this error:
NoMethodError - undefined method `image_video_file_name' for #<Comment:0x007f5a082a4310>:

This error only occurs when I attempt to throw an array of Medium to the Serializer. With only one Medium I get no errors and the result is this:
As you can see it has all the attributes I wanted it to have in the serializer and it managed to fetch the info into all the attributes with no problems.
Why does this problem occur only when I do the same thing with an array or same objects?
