[09:13:21] thesubr00t: How to optimize ActiveRecord::Base.connection.execute() for a large data. I'm experiencing a memory bloat on production loading ~ 50k row on a server with ~60kmb of RAM !
[09:14:50] thesubr00t: I use Postgresql
[09:24:09] thesubr00t: blackcross_, im storing the result in an Enumerator to stream it as a CSV file, something like "result.each_row { |row| yielder << CSV.generate_line(row) }. How to do that in chunks ?

[12:42:34] thesubr00t: Is there a helper to get the URI pattern for a specific path ?
[12:43:31] thesubr00t: dminuoso, yes programmatically
[12:44:12] thesubr00t: I need to send the pattern to a frontend client in a json response
[12:45:43] thesubr00t: dminuoso, I just need a helper like `something_path` to return the pattern, ex (users/:id)
[12:48:43] thesubr00t: dminuoso, well I'm sending a bunch of urls pattern to the front, so basically a clean approach is what I'm looking for.
[12:49:09] thesubr00t: dminuoso, but tell me what you have in mind ;-)
[12:57:03] thesubr00t: dminuoso, Okay thanks ! :-)
[13:15:48] thesubr00t: dminuoso, Thank you mate ! That will point me to the right direction

[15:31:06] thesubr00t: I'm trying to define a method inside a BaseSerializer class (parent class of other serializers) to transform all string attributes, but my implementation does not work. Please point me to the right direction. Here is a gist
[15:33:24] thesubr00t: it does not seem to define the methods as I want, but when i replace object.attributes.symbolize_keys.each_key with a list of manually typed attributes and move it out of the "attributes" method it works
[15:36:45] thesubr00t: Sure, here is the other class
[15:37:51] thesubr00t: sevenseacat, allcentury AMS v 0.10.6
[15:39:45] thesubr00t: allcentury, the object's list of attributes as symbols
[15:41:15] thesubr00t: sevenseacat, sorry its a hash with attributes as symbolized keys

[15:47:07] thesubr00t: sevenseacat, I'm expecting them to be defined on the child class's
[15:47:35] thesubr00t: Im trying to DRY that bit of code by defining it in the parent class
[15:47:52] thesubr00t: QuestionSerializer < BaseSerializer
[15:49:16] thesubr00t: sevenseacat, I'm expecting them to be defined on the QuestionSerializer class
[15:53:46] thesubr00t: sevenseacat, I test it by defining the method on the same class with no luck
[15:55:12] thesubr00t: The gsub part is not working
[16:04:10] thesubr00t: sevenseacat, allcentury
[16:06:53] thesubr00t: How to define it as a class method then?
[16:14:18] thesubr00t: allcentury, undefined method `id' for QuestionSerializer:Class

[11:00:06] thesubr00t: Here is the service
[11:02:28] thesubr00t: dminuoso, the service is responsible for generating a CSV file, does that mean that I should compare the result with a pregenerated file?
[11:05:01] thesubr00t: dminuoso, I've tried with instance_double & recieve(:call) but I get:

[11:09:18] thesubr00t: dminuoso, Its a Rails service
[11:10:37] thesubr00t: dminuoso, So how should I implement that?
[11:13:22] thesubr00t: dminuoso, Ok thanks :)

[13:21:03] thesubr00t: dminuoso, I want to deploy the same code base once and serving a single server.
[13:22:23] thesubr00t: dminuoso, I know I can use RCA along with a Procfile, but I prefer using webpacker with React

[13:26:32] thesubr00t: By the way do you know any good react/redux boilerplate?

[14:19:57] thesubr00t: This may not be rails related, but I'm having some difficulty solving this quiz:
[14:20:06] thesubr00t: Any help will be appreciated
[14:24:27] thesubr00t: dminuoso, sevenseacat, yes it is. I'm doing well so far but I think it's missing some cases. The big issue is how to calculate the total possible route when a rider is delivering more than one order
[14:26:23] thesubr00t: He is not a ruby/rails developer. He got the quiz from a friend ..
[14:28:19] thesubr00t: ljarvis, this is my actual code
[14:29:13] thesubr00t: I think there is some case missing, example for example when rider is delivering multiple orders, how to calculate the route time correctly
[14:31:04] thesubr00t: sevenseacat, dminuoso, As I said I am 80% done with all cases :)
[14:31:11] thesubr00t: But I got your points
[14:33:28] thesubr00t: sevenseacat, here is my code so far
[14:36:56] thesubr00t: mauro1254, I think you should respond with a json representation for all http errors, specially if you are following the JSONAPI specs
[14:37:07] thesubr00t: sevenseacat, my bad :)
[14:38:41] thesubr00t: You have to rescue each type of them individually
[14:58:28] thesubr00t: mauro1254, Yes that a way to do it

[13:15:04] thesubr00t: I already enabled postgreSQL extension & set application generator to use uuid for future tables. How can I change the old tables?
[13:16:08] thesubr00t: sevenseacat, Is it that hard? :D
[13:17:25] thesubr00t: sevenseacat, It's easy to start using uuid for primary_keys, my only concern is about my old tables/data
[13:28:07] thesubr00t: pontiki_, sure! I am looking for some best practices and advices
[13:30:06] thesubr00t: pontiki_, I'll do that. Thank you :)
[13:35:13] thesubr00t: pontiki_, True. I think that will be complicated because I am using jsonapi-resource to serve my API, and it insist that the ORM uses the uuid as default if I need to change the finder key
[13:36:10] thesubr00t: pontiki_, That's why I think to change the id type to uuid
[13:39:43] thesubr00t: pontiki_, Thank you for your suggestions, they are helpful :)

[21:46:33] thesubr00t: I have an application that uses Devise omniauthable with facebook & twitter, since twitter does not provide the user email in the auth hash, how to fetchan already created user when autheticating from twitter
[21:46:54] thesubr00t: is there a way?
[21:50:15] thesubr00t: mikecmpbll,provider & uid are different for each authorization
[21:50:50] thesubr00t: mikecmpbll, uid from twitter is not the same uid from facebook
[21:54:27] thesubr00t: mikecmpbll, Thats true. When I first authenticate with facebook than I signout, then autheticate with twitter, it will be a whole new user
[21:54:35] thesubr00t: mikecmpbll, check this line
[21:55:10] thesubr00t: mikecmpbll, twitter does not give emails
[21:59:31] thesubr00t: mikecmpbll, yeah! devise rely on the email which twitter doesn't provide for oauth
[22:00:50] thesubr00t: mikecmpbll, I couldn't find another way since I'm using Devise
[22:02:22] thesubr00t: mikecmpbll, I'm using them too, the problem remains
[22:06:42] thesubr00t: user has_many authorization, if a user signup using facebook first, he will have an authorization with provider: "facebook" & uid: "some_uid_from_facebook". Now if he logout then signin using twitter he will have another authorization with provider: "twitter" & uid: "some_uid_from_twitter". when with facebook he will have email, when with twitter there is no email. thats why the problem remains
[22:07:35] thesubr00t: mikecmpbll, make sense?
[22:08:25] thesubr00t: mikecmpbll, yep
[22:11:00] thesubr00t: mikecmpbll, I already did that, and it works perfectly. My problem now is when logging from facebook then logout & login with google-plus from example devise finds the user created from facebook, but in case of twitter it will create a whole new user.
[22:12:47] thesubr00t: mikecmpbll, the user does not have an authorization from twitter unless he first login with it.
[22:16:23] thesubr00t: mikecmpbll, Yes, that's what I'm looking for :)
[22:16:54] thesubr00t: mikecmpbll, otherwise that workflow s right
[22:17:49] thesubr00t: mikecmpbll, here is what you get from twitter
[22:20:46] thesubr00t: mikecmpbll, yes that way they can hijack others acoounts
[22:26:00] thesubr00t: matthewd, Can you please elaborate?
[22:26:38] thesubr00t: matthewd, I mean a mechanism like what?
[22:28:01] thesubr00t: matthewd, Looks like a solution. I'm going to test it. Thanks for the suggestion!

[11:00:40] thesubr00t: n_e_o, I want to be able to use `current_user.social_accounts` wich will iterate on all of them, and `current_user.grouped_social_accounts` to iterate on the limited set of social accounts.

[11:11:37] thesubr00t: alfie_max15, does it make sense?
[11:12:22] thesubr00t: think of it like facebook messages & groups messages
[11:15:15] thesubr00t: I may use join table for that

[11:15:31] thesubr00t: thank you for the hint

[11:17:34] thesubr00t: ok, thank you!
[11:33:19] thesubr00t: axilla, The simplest way I can think of is that products have a `approved` boolean attribute with default to false.
[11:35:13] thesubr00t: Then it's up to you to flag it as approved bu updating that attribute to true
