When I create a new admin user, there are three objects of translations:
Admin.last.translations.map(&:locale) # => [:ru, :uz, :uz]
Why are the locales duplicated?
Example:
admin.position_uz = 'CTO'
admin.position_ru = 'CTO'
admin.save!
admin.translations.count = 3
admin.translations.first.position = 'CTO'
admin.translations.second.position = 'Another value or empty'
admin.translations.third.position = 'CTO'
Every time the locale is set to uz, it shows the second variant.
Admin translations loo like
[
#<Admin::Translation id: 1, admin_id: 2, locale: "ru", position: "CTO", created_at: "2019-01-16 06:24:17", updated_at: "2019-01-16 06:30:31">,
#<Admin::Translation id: 2, admin_id: 2, locale: "uz", position: "Board Member", created_at: "2015-07-26 20:42:18", updated_at: "2015-07-26 20:42:18">,
#<Admin::Translation id: 3, admin_id: 2, locale: "uz", position: "CS manager", created_at: "2019-01-16 06:24:17", updated_at: "2019-01-16 07:09:21">

I have a model called Event, where I have stored_accessor "list" (stored like data: {"list"=>[{"key"=>"key1", "value"=>"value1"}]}).
I need to make a search query o
#<Event id: "1", title: "HHHH", description: nil, data: {"list"=>[{"key"=>"key1", "value"=>"value1"}, {"key"=>"key2", "value"=>"value2"}]}, created_at: "2017-04-14 21:06:22", updated_at: "2017-04-20 10:36:08">
#<Event id: "2", title: "HHHH", description: nil, data: {"list"=>[{"key"=>"key1", "value"=>"value1"}]}, created_at: "2017-04-14 21:06:22", updated_at: "2017-04-20 10:36:08">
#<Event id: "3", title: "HHHH", description: nil, data: {"list"=>[{"key"=>"key11", "value"=>"value11"}, {"key"=>"key12", "value"=>"value12"}]}, created_at: "2017-04-14 21:07:22", updated_at: "2017-04-20 10:37:08">
#<Event id: "4", title: "HHHH", description: nil, data: {"list"=>[{"key"=>"key111", "value"=>"value111"}, {"key"=>"key112", "value"=>"value112"}]}, created_at: "2017-04-14 21:08:22", updated_at: "2017-04-20 10:38:08">
I have a serach params like
1) {'key'=> 'key1', 'value'=> 'value1'}
2) ["key"=>"key1", "value"=>"value1"}, {"key"=>"key2", "value"=>"value2"}]
In first case, it should return Event id 1 and 2.
In second case, it should return Event id 1. (event if return 1 and 2 both could be acceptable).
I am not sure with json and array combination.
Please help.
You may do it with PostgreSQL jsonb's operator #>. Also you need to write the full path for search params: {'list' => [{'key'=> 'key1', 'value'=> 'value1'}]}. Try this code:
to_contain1 = {'list' => [{'key'=> 'key1', 'value'=> 'value1'}]}
to_contain2 = {'list' => [{'key'=> 'key2', 'value'=> 'value2'}]}
Event.
where("data #> ?", to_contain1.to_json})
# returns events 1 & 2
Event.
where("data #> ?", to_contain1.to_json).
where("data #> ?", to_contain2.to_json)
# returns event 1
I have a collection of user.paid_subscriptions in which each subscription has attributes created_at(datetime) and active(boolean).
How can I check if a PaidSubscription exists such that created_at is not equal to a certain date and active is true?
PaidSubscription looks like this:
[
#<PaidSubscription id: 11457,
user_id: 12,
period: 3,
price: 4000,
expires_at: "2016-03-08 09:44:56",
expires_at: "2016-03-08 09:44:56",
created_at: "2015-12-08 09:44:56",
updated_at: "2016-03-08 23:00:09",
active: false,
giver_id: 20573,
partial: false,
remaining_days: 0>,
#<PaidSubscription id: 13948,
user_id: 12,
period: 1,
price: 1500,
expires_at: "2016-04-11 12:07:40",
created_at: "2016-03-11 13:07:40",
updated_at: "2016-04-11 22:00:11",
active: false,
giver_id: nil,
partial: false,
remaining_days: 0>,
#<PaidSubscription id: 11458....
]
Try this,
If it is a query then it should be like this
user.paid_subscriptions.where("created_at < :date or created_at > :date and active = :active",{date: DateTime.civil(yyyy,mm,dd), active: true})
Or
if it is an array you can use it like below.
user.paid_subscriptions.any? {|ps| ps.active && ( ps.created_at.to_date < Date.civil(yyyy, mm, dd) || ps.created_at.to_date > Date.civil(yyyy, mm, dd))}
When I call:
preivous_lessons = #item.where("track_id = ?", lesson.track_id)
I get this active record realtion:
[#<CodeLesson id: 2, name: "Python", permalink: "python", lesson_content: "", instructions: "Print your name to the console.", hints: "", starting_code: "\"\"\"\r\nThis is a comment\r\n\"\"\"\r\n\r\nprint(\"Hello, World\"...", language_id: "12", order: 1, track_id: 2, user_id: 1, created_at: "2014-02-14 16:01:12", updated_at: "2014-02-15 21:14:43", visible: true>, #<CodeLesson id: 8, name: "Test Lesson", permalink: "test-lesson", lesson_content: nil, instructions: nil, hints: nil, starting_code: nil, language_id: "26", order: nil, track_id: 2, user_id: 1, created_at: "2014-02-20 19:23:15", updated_at: "2014-02-20 19:23:15", visible: false>]
How do I convert this into a usable array of models so I can do something like this:
preivous_lessons.each do |i|
highest = i.order if i.order > highest
end
As OP confirmed from my comment, that my hint solved his problem, I am putting it as an answer to the post :
preivous_lessons = #item.where("track_id = ?", lesson.track_id)
highest = preivous_lessons.maximum(:order)
Documentation of maximum :
Calculates the maximum value on a given column. The value is returned with the same data type of the column, or nil if there's no row.
preivous_lessons = #item.where("track_id = ?", lesson.track_id).all
I have such array data:
[#<PriceList id: 463134, distributor_id: 6, brand: "Mann-filter", article_nr: "W712/22", price: 5405.0, quantity: "50", waittime: 1, description: "Фильтр масл OPEL 1.2-3.0L (OC90)", created_at: "2013-01-30 16:35:34", updated_at: "2013-01-30 16:35:34", art_group: "Фильтр масл OPEL 1.2-3.0L (OC90)", oem_number: nil>, #<PriceList id: 517164, distributor_id: 6, brand: "Mann-filter", article_nr: "W712/22", price: 5442.0, quantity: "500", waittime: 3, description: "Фильтр масляный OPEL/GM/DAEWOO", created_at: "2013-01-30 16:42:26", updated_at: "2013-01-30 16:42:26", art_group: "Фильтр масляный OPEL/GM/DAEWOO", oem_number: nil>, #<PriceList id: 463135, distributor_id: 6, brand: "Mann-filter", article_nr: "W712/22(10)", price: 5101.0, quantity: "20", waittime: 1, description: "Фильтр масл.без упак.OPEL/GM (OC90Of)", created_at: "2013-01-30 16:35:34", updated_at: "2013-01-30 16:35:34", art_group: "Фильтр масл.без упак.OPEL/GM (OC90Of)", oem_number: nil>, ... etc
how can i change price type?
i try
#non_original2 = #non_original2.map { |e| e[:price].to_i }
but as result i see only price values... How can i change my array, so that price field in all hashes become integer value?
what about
#non_original2.each { |e| e[:price] = e[:price].to_i }
This changes every PriceList item in the list (and does not copy the list).
Using your approach results in a list of price values, because map collects the result of the block. The result of e[:price].to_i is an integer (the prices you see).
I use the following query to return a list of records
Rating.find(:all, :conditions => ["rating_set = ? and product_id = ?", 1, 2186417])
which returns:
[#<Rating id: 5, label: "Good", rating: 3.0, created_at: "2013-02-20 08:11:36", updated_at: "2013-02-20 08:11:36", recommendation_id: 2186417, notes: "exact match", rating_set: 1, product_id: 2186417>, #<Rating id: 6, label: "Good", rating: 3.0, created_at: "2013-02-20 08:11:36", updated_at: "2013-02-20 08:11:36", recommendation_id: 2054442, notes: "", rating_set: 1, product_id: 2186417>, #<Rating id: 7, label: "Fair", rating: 2.0, created_at: "2013-02-20 08:11:36", updated_at: "2013-02-20 08:11:36", recommendation_id: 2403501, notes: "", rating_set: 1, product_id: 2186417>, #<Rating id: 8, label: "Bad", rating: 3.0, created_at: "2013-02-20 08:11:36", updated_at: "2013-02-20 08:11:36", recommendation_id: 2344645, notes: "", rating_set: 1, product_id: 2186417>]
How can I get a count for each rating label. For example, how many records out of the total are "Good" or how many are "Bad" etc.
You can do that in at least 2 ways.
SQL
klass = Rating.where(rating_set: 1, product_id: 2186417])
good_count = klass.where(label: 'Good').count
bad_count = klass.where(label: 'Bad').count
Array
ratings = Rating.where(rating_set: 1, product_id: 2186417]).all
good_count = ratings.count { |r| r.label == 'Good' }
bad_count = ratings.count { |r| r.label == 'Bad' }
You could try a group by:
Rating.where(:rating_set => 1, :product_id => 2186417).group(:label).count.each{ |k,v| puts "#{k} #{v}" }
