Hi everyone, i have a problem with a complex eager loading scenario. I have a data model like this:
class Closure < ApplicationRecord
has_and_belongs_to_many :geo_refs
end
class GeoRef < ApplicationRecord
endI use to cancancan gem for filtering both record types by users permissions.
So my current query looks like this:
@closures = Closures.includes(:geo_refs).accessible_by(current_ability, :read)But that will of course eager load all GeoRef of a closure. Not just the one accessible by the user. I need to apply the accessible_by filter again for the eager loaded association.
@geo_refs = GeoRef.joins(:closures).where('closures.id': @closures).accessible_by(current_ability, :read)closures.id?Like:
{ 1: [#<GeoRef id:1>, #<GeoRef id:2>], 2: [...] }@geo_refs = GeoRef.joins(:closures).where('closures.id': @closures).accessible_by(current_ability, :read) \
.select('closures.id AS closure_id, geo_refs.*').index_by(&:closure_id)
I suggest going through this book from Launchschool, there's a whole section dedicated to RVM.
https://launchschool.com/books/core_ruby_tools/read/ruby_version_managers#rvm
If you do a
type rvmit should output function, if not you need to reinstall it.
Hi @ScottG489, with HTTP2 you can do stream prioritization.
Never implemented it myself but have a look here (scroll down to the Stream Prio paragraph):

Definitely something to learn here
I have this model Person
class Person
generate_public_uid generator: PublicUid::Generators::HexStringSecureRandom.new(32)
has_many :addresses, as: :resource, dependent: :destroy
accepts_nested_attributes_for :addresses, allow_destroy: true, update_only: true,
reject_if: proc { |attrs| attrs[:content].blank? }
endin my person table, I have this public_id that is automatic generated when a person is created. now the nested attribute in adding addresses is working fine. but the update is not the same as what nested attribute default does. my goal is to update the addresses using public_id
class Address
generate_public_uid generator: PublicUid::Generators::HexStringSecureRandom.new(32)
belongs_to :resource, polymorphic: true end
this is my address model
I'm using the public id to my primary key. and trying to update nested attribute using the public_id
private method?" ?
class Testit
def private
puts 'ok, its private then'
private_thing
end
private
def private_thing
puts ' test'
end
end
a = Testit.new
a.private
# ok, its private then
# testprivate messes up the class:
class Plop
def self.private
puts 'yep?'
end
private
def self.plop
private
end
end
yep?
=> :plopprivate() is called on class definition...
enum status: [:published, :unpublished, :not_set]
end
catalog.published? is an instance method; an instance method named private seems ok (example. 1)
Catalog.status to get the enum)
nature enum, Rails creates MyClass.natures
environment rake task to get the rails environment inside
