cách sử dụng ransackable_scopes trong ROR
model code:
scope :with_active_subscription, -> (flag = nil) {
pp "Value received: #{flag.inspect}"
return all if flag.blank? || flag.to_s == ''
if flag.to_s == 'true'
# Logic cho true case
where(has_active_subscription: true)
elsif flag.to_s == 'false'
# Logic cho false case
where(has_active_subscription: false)
else
all
end
}
class << self
def ransackable_scopes(auth_object = nil)
%w[with_active_subscription]
end
end
controller code:
# GET /products
def index
@q = Product.ransack(search_params)
@products = @q.result(distinct: true)
end
private
def search_params
params.fetch(:q, {}).permit(
:with_active_subscription,
)
end
=> hiện không nhận được giá trị của flag trong "scope :with_active_subscription", mọi người giúp mình với.

class << self
def ransackable_scopes(auth_object = nil)
[:with_active_subscription] # <-- dùng symbol
end
end

Theo ý kiến cá nhân của mình, thì có thể sửa lại code cho gọn như sau:
# GET /products
def index
@products = Product.with_active_subscription(params[:is_active_subscription])
end
# model
scope :with_active_subscription, -> (flag) {
flag = ActiveModel::Type::Boolean.new.cast(flag)
return if flag.blank?
where(has_active_subscription: flag)
}

Interesting article on ransackable_scopes in Rails! I found it particularly helpful for creating custom search logic. I'd suggest adding examples showcasing how to use these scopes with complex queries, perhaps involving multiple tables. I use this when playing Wordle Unlimited , so the search logic is important. Is there any consideration on using ransackable_scopes when it comes to performance? I'm thinking about scaling the app in the near future. Thanks for the insights!

Right, ransackable_scopes, huh? My mind immediately goes to customized searches. Scope creep isn't just a project management nightmare; it's a search query challenge too! Oh, you want that kind of filtered data? Ransack to the rescue! Remember that time I built a job board where the filtering kept breaking, making relevant jobs impossible to find? It was a complete mess, debugging for days. Sharing my pain is a lot like surviving a tricky level in the Slope Game, so I'll just say good riddance to those days.

Ransack and scopes, eh? Been there. So, dynamically toggling active subscriptions, got it. Flag values mysteriously vanishing, sounds familiar. Scopes in Rails, sometimes they play hard to get. Ah, the joys of debugging! This reminds me of wrestling with a custom search function that stubbornly ignored my date range inputs. I finally realized the issue was with how I was serializing the dates in the URL – total block breaker moment when I fixed that serialization!

Exploring ransackable_scopes in Ruby on Rails offers a powerful way to customize search functionality beyond basic attributes. I remember once struggling to filter complex queries in a Rails app and found that scopes integrated with Ransack made the process much smoother. For anyone experimenting with search tools, Omegle conversations about coding challenges often spark helpful ideas and solutions.
Exploring how to use ransackable_scopes in Ruby on Rails opens up many possibilities for customizing search queries. I remember once struggling with filtering complex datasets until I discovered a method quite like this. It allowed me to create cleaner, reusable scopes that transformed the querying process. If you ever shop around solutions like Monkey Mart, you'll find tools that simplify intricate filtering just as effectively.

This is a neat example of using ransackable scopes! I especially appreciate the handling of blank flags to return all. I've often struggled with how to make scopes flexible enough to handle different user inputs in search forms. I wonder if this approach would also work well for implementing something like a filter for archived items. Speaking of filters, sometimes figuring out the logic feels as challenging as beating my high score in the Dinosaur Game! Thanks for sharing this.

I love Drift Boss because it brings ‘relaxation’ and ‘satisfaction’ in a gentle way. No need to be ‘stressed’ or pressured, just enjoy the ‘smooth’ and ‘rhythmic’ drifting. A perfect game to ‘let off steam’!

Great guide on how to use ransackable_scopes in ROR. It is very helpful for those looking to improve their filtering in Rails projects. I was able to set up custom search scopes easily following your explanation. By the way, this reminds me of the strategic upgrades in Cookie Clicker , where the right setup makes a huge difference in performance.
