Rails 3: How to display an object in a readable format? - ruby-on-rails

Displaying an object like this:
Job.find(4).inspect
results in:
#<Job id: 4, job_date: "2010-10-22", address: "some address", invoice_number: "b432", client_name: "Fred", client_email: "fred#yahoo.com", client_mobile_number: "12345678", ...>
which is not very readable.
Is there a simple way to display the object like this:
id: 4
job_date: "2010-10-22"
address: "some address"
invoice_number: "b432"
client_name: "Fred"
client_email: "fred#yahoo.com"
client_mobile_number: "12345678"
or some other readable way ?

Not sure where you are looking to display this, but for the console/debugger I recommend the awesome_print gem.

Printing a rails object example from gem readme:
ap Account.all(:limit => 2)
[
[0] #<Account:0x1033220b8> {
:id => 1,
:user_id => 5,
:assigned_to => 7,
:name => "Hayes-DuBuque",
:access => "Public",
:website => "http://www.hayesdubuque.com",
:toll_free_phone => "1-800-932-6571",
:phone => "(111)549-5002",
:fax => "(349)415-2266",
:deleted_at => nil,
:created_at => Sat, 06 Mar 2010 09:46:10 UTC +00:00,
:updated_at => Sat, 06 Mar 2010 16:33:10 UTC +00:00,
:email => "info#hayesdubuque.com",
:background_info => nil
},
[1] #<Account:0x103321ff0> {
:id => 2,
:user_id => 4,
:assigned_to => 4,
:name => "Ziemann-Streich",
:access => "Public",
:website => "http://www.ziemannstreich.com",
:toll_free_phone => "1-800-871-0619",
:phone => "(042)056-1534",
:fax => "(106)017-8792",
:deleted_at => nil,
:created_at => Tue, 09 Feb 2010 13:32:10 UTC +00:00,
:updated_at => Tue, 09 Feb 2010 20:05:01 UTC +00:00,
:email => "info#ziemannstreich.com",
:background_info => nil
}
]

The formatting is similar if you do raise Job.find(4).to_yaml

factory_bot build_stubbed strategy

The factory_bot documentation for build strategies says:
factory_bot supports several different build strategies: build, create, attributes_for and build_stubbed
And continues with some examples of usage. However, it doesn't clearly state what the result of each one is. I've been using create and build for a while now. attributes_for seems straightforward from the description and I see some uses for it. However, what is build_stubbed? The description says
Returns an object with all defined attributes stubbed out
What does "stubbed out" mean? How is this different from either create or build?
Let's consider the difference on the example of these factories:
FactoryBot.define do
factory :post do
user
title { 'Post title' }
body { 'Post body' }
end
end
FactoryBot.define do
factory :user do
first_name { 'John' }
last_name { 'Doe' }
end
end
build
With build method everything is easy. It returns a Post instance that's not saved
# initialization
post = FactoryBot.build(:post)
# call
p post
p post.user
# output
#<Post:0x00007fd10f824168> {
:id => nil,
:user_id => nil,
:title => "Post title",
:body => "Post body",
:created_at => nil,
:updated_at => nil
}
#<User:0x00007f8792ed9290> {
:id => nil,
:first_name => "Post title",
:last_name => "Post body",
:created_at => nil,
:updated_at => nil
}
Post.all # => []
User.all # => []
create
With create everything is also quite obvious. It saves and returns a Post instance. But it calls all validations and callbacks and also creates associated instance of User
# initialization
post = FactoryBot.create(:post)
# call
p post
p post.user
# output
#<Post:0x00007fd10f824168> {
:id => 1,
:user_id => 1,
:title => "Post title",
:body => "Post body",
:created_at => Sat, 18 Jun 2022 05:32:17.122906000 UTC +00:00,
:updated_at => Sat, 18 Jun 2022 05:32:17.122906000 UTC +00:00
}
#<User:0x00007f8792ed9290> {
:id => 1,
:first_name => "John",
:last_name => "Joe",
:created_at => Sat, 18 Jun 2022 05:32:17.122906000 UTC +00:00,
:updated_at => Sat, 18 Jun 2022 05:32:17.122906000 UTC +00:00
}
Post record and associated user record were created in the database:
Post.all # => [<Post:0x00007fd10f824168> {...}]
# User also created in the database
User.all # => [<User:0x00007f91af405b30> {...}]
build_stubbed
build_stubbed imitates creating. It slubs id, created_at, updated_at and user_id attributes. Also it skips all validations and callbacks.
Stubs means that FactoryBot just initialize object and assigns values to the id created_at and updated_at attributes so that it just looks like created. For id it assign integer number 1001 (1001 is just default number what FactoryBot uses to assign to id), for created_at and updated_at assigns current datetime. And for every other record created with build_stubbed is will increment number to be assigned to id by 1.
First FactoryBot initialize user record and assign 1001 to id attribute but not save it to the database than it initialize post record and assing 1002 to the id attribute and 1001 to user_id attribute to make association, but also doesn't save record to the database.
See example below.
#initialization
post = FactoryBot.build_stubbed(:post)
# call
p post
p post.user
# output
# It looks like persisted instance
#<Post:0x00007fd10f824168> {
:id => 1002,
:user_id => 1001,
:title => "Post title",
:body => "Post body",
:created_at => Sat, 18 Jun 2022 05:32:17.122906000 UTC +00:00,
:updated_at => Sat, 18 Jun 2022 05:32:17.122906000 UTC +00:00
}
#<User:0x00007f8792ed9290> {
:id => 1001,
:first_name => "John",
:last_name => "Joe",
:created_at => Sat, 18 Jun 2022 05:32:17.122906000 UTC +00:00,
:updated_at => Sat, 18 Jun 2022 05:32:17.122906000 UTC +00:00
}
Post and user records were not created in the database!!!
# it is not persisted in the database
Post.all # => []
# Association was also just stubbed(initialized) and there are no users in the database.
User.all # => []

Rspec rails : check if object.value is false

I'm testing a cron job in rails and I want to test if an attribute of object to be false by default, this the portion of code that do the job :
describe ".perform()" do
before :each do
SendReportCronJob.perform()
end
context "automatically_send_report" do
it "should be false by default" do
binding.pry()
expect( automatically_send_report.value ).to be "false"
end
end
context "time_limit" do
it "should not be nil" do
expect( time_limit_for_sending_report.value ).to_not be_nil
end
end
end
the problem is the automatically_send_report.value return a "false" value !
here the output of rails console when I do binding.pry() :
#<Setting:0x00000009990878> {
:id => "69617295-4209-4092-80cf-5934d1cf7d38",
:related_id => "cd830ace-933a-4230-ad54-bd94e63d5d7b",
:key => "automatically_send_report",
:value => "false",
:data_type => "boolean",
:is_archived => false,
:updated_by_id => nil,
:device_id => nil,
:created_at => Wed, 18 Apr 2018 18:34:35 +03 +03:00,
:updated_at => Wed, 18 Apr 2018 18:34:35 +03 +03:00
}
can I convert this value from string to boolean in the rspec file ?
You don't need to convert the string to boolean, you can compare strings as well, but in that case you need to use eq instead of be, as they are different objects with the same value:
expect(automatically_send_report.value).to eq "false"

How to validate :created_at in model (RAILS 3)

irb(main):044:0> i1.created_at
=> Thu, 24 Apr 2014 02:41:15 UTC +00:00
irb(main):045:0> i2.created_at
=> Thu, 24 Apr 2014 02:41:15 UTC +00:00
irb(main):046:0> i1.created_at == i2.created_at
=> false
irb(main):047:0> i1.created_at.to_time.to_i == i2.created_at.to_time.to_i
=> true
Seems not to work validates_uniqueness_of :created_at
because
irb(main):046:0> i1.created_at == i2.created_at
=> false
How to validate created_at? Don't want to save with the same date.
+++ UPDATE +++
irb(main):048:0> i1.created_at.class
=> ActiveSupport::TimeWithZone
irb(main):049:0> i2.created_at.class
=> ActiveSupport::TimeWithZone
Since they might have different precision milliseconds.
Refer to the post: Testing ActiveSupport::TimeWithZone objects for equality
Chances are the millisecond values would be unequal.
puts i1.created_at.usec
puts i2.created_at.usec
I think, if you are getting concurrent requests, there are chances that you may have multiple entries in the table which are created at same time and will have same time stamps.
As you said, if you don't want to save with the same date, you can put a lock while saving the entries, removing the possibility of creating two entries at same time. In that case validates_uniqueness_of :created_at should also work.
Just in case
class Item < ActiveRecord::Base
attr_accessible :asin, :domain, :formatted_price, :user_id, :created_at
validate :double_dates
private
def double_dates
if Item.where(:user_id => self.user_id, :asin => self.asin, :domain => self.domain).where("DATE(created_at) = ?", Date.today).length >= 1
errors.add(:created_at, "no double dates")
end
end
end

Wrong boolean result comparing Date objects

I'm trying to write test that compare some dates. So far i have 2 tests, one of them works as intended, but the other one fails because doesnt/not correctly compare dates.
Here is my code:
def self.has_expired?(card, start_month, start_year, annually)
card_date = Date.new(card.year, card.month, -1)
billing_date = Date.new(start_year, start_month, -1)
if !annually
p '--------'
p card_date
p billing_date
card_date > billing_date
else
#return false
end
end
creditcard object
creditcard = ActiveMerchant::Billing::CreditCard.new(
:number => 1234567890123456
:month => 01,
:year => 13,
:first_name => 'John',
:last_name => 'Doe',
:verification_value => 132,
:brand => 'visa'
)
Here is output of p's
First block works as intended.
"--------"
Tue, 31 Jan 0013
Thu, 28 Feb 2013
false
Second block fails, expecting true, but got false
."--------"
Tue, 31 Jan 0013
Fri, 30 Nov 2012
false
Here is my rspec code
describe CreditCard do
context 'card_expired' do
it 'should return false with args passed to method (02month, 13 year, annually==false)' do
CreditCard.has_expired?(creditcard, 02, 2013, false).should == false
end
it 'should return true with args passed to method (11month, 12 year, annually==false)' do
CreditCard.has_expired?(creditcard, 11, 2012, false).should == true
end
end
end
in irb it works as charm, returning correct value(true/false)
I think the problem is in your logic. A card is expired when the expiration date is before the billing date, thus when
card_date < billing_date # expired
and not when
card_date > billing_date # valid
Also try puting in the full 2013 and see if that helps if it keeps breaking
:year => 2013,
You're also missing a comma after this line (probably a copy/paste error) :number => 1234567890123456

Factory girl Timestamps issue

I was using the following code to generate 3 mocks:
# today is 27.02
order1 = Factory(:order, :created_at => Date.yesterday) # created_all is 25.02?
order2 = Factory(:order, :quantity => 2, :created_at => Date.today) # created_all is 26.02??
order3 = Factory(:order, :created_at => Date.today) # created_all is 26.02???
In order to have the date set right I use:
order1 = Factory(:order, :created_at => 1.days.ago)
order2 = Factory(:order, :quantity => 2, :created_at => Time.now)
order3 = Factory(:order, :created_at => Time.now)
Any idea what is the diffrence betwen Date.today and Time.now ?
Thank you,
First they are instances of different classes, and represent different info:
Date contains only date information, and Time contains all the date, time, and timezone info
>> Date.today
=> #<Date: 2012-02-27 (4911969/2,0,2299161)>
>> Time.now
=> 2012-02-27 14:14:22 +0200
In your example both Date.today and Time.now will be type-casted to the type you have in db (date or time)
>> Time.now
=> 2012-02-27 14:14:22 +0200
>> Time.now.to_date
=> #<Date: 2012-02-27 (4911969/2,0,2299161)>
>> Time.now.to_date.to_time
=> 2012-02-27 00:00:00 +0200
