| Rails - Issue with permitting params & require Posted: 07 Dec 2016 07:40 AM PST I'm having an issue with submitting my params, portrait and portrait_tag are passed through my form and are siblings, how would I go permitting both of these?
Output {"utf8"=>"✓", "_method"=>"patch", "authenticity_token"=>"", "portrait"=>{"artist_image"= "", @original_filename="rubytraining.jpg", @content_type="image/jpeg"}, "portrait_tag"=>{"tag_ids"=>["", "1", "2", "3", "4"]}, "commit"=>"Save changes", "controller"=>"admin/portraits", "action"=>"update", "id"=>"72"}
I've tried the following private def portrait_params params.require(:portrait).permit(:id, :artist_image) params.require(:portrait_tag).permit(:id, :tag => []) end
These work separately but overwrite one another when added together controller def update @portrait = Portrait.where(artist_id: 33, id: params[:id]).take if @portrait.update(portrait_params) redirect_to :edit_admin_portrait, flash: {notice: "Successfully updated your information"} else flash[:system] = @portrait.errors.full_messages p @portrait.errors.full_messages render :edit end end private def portrait_params params.require(:portrait).permit(:id, :artist_image) params.require(:portrait_tag).permit(:id, :tag => []) end

| Rails4 security: Session fixation possible at all using encrypted cookies? Posted: 07 Dec 2016 07:43 AM PST After studying the rails guide and some other ressources I'm wondering how a session fixation attack on a user's session can actually happen. At least I'm sceptical it works as simple as depicted here in the guide, where an attacker... 1) ...creates a valid session by logging in 2) ...keeps the session alive 3) ...then forces the user to use his session's id e.g. by using some XSS vulnerability All fine, but... how would the attacker be able to gather the value of his own session id? By default cookies are encrypted in Rails4+. So what to do as an attacker assuming I do not have access to secret_key_base or whatever is used to generate the encryption and signature keys? From what I understand he cannot tamper with the cookie without invalidating it (signature wrong) so somehow passing a self-created cookie to a possible victim is neither an option. Is the secu guide kind of not up to date or am I missing a point here? If the latter then... a) how [as an attacker] can I read encrypted cookie information b) how does a vulnerability have to look like that allows me [the attacker] to inject that session id into the likewise encrypted cookie on another client? Would that be an XSS attack? The guide states that if an attacker uses code like <script>document.cookie="_session_id=16d5b78abb28e3d6206b60f22a03c8d9";</script>
he would be able to fix that session. But again, why would rails reveal it's plain session to the client making it accessible via client-side processed javascript? It does not, which is why all my cookie-values are simple gibberish not being accessible by Javascript (can test that via console). Thanks for any advice! |

| Rails different sql between scope and explicit join Posted: 07 Dec 2016 07:32 AM PST I have models with these associations: class Event < ActiveRecord::Base has_many :memberships, dependent: :destroy has_many :users, through: :memberships end class Membership < ActiveRecord::Base belongs_to :user belongs_to :event end
And following methods: #In Membership scope :available_for, -> (user) { joins(:event).merge(Event.available_for(user)) } #In Event def self.available_for(user) ... joins(:memberships).where('memberships.user_id': user.id).ids ... end
So in controller when I call: @memberships = @user.memberships.available_for(current_user)
Apparently is not the same as: @memberships = @user.memberships.joins(:event).merge(Event.available_for(current_user))
In first case it works not as expected, it adds extra AND while join in sql: SELECT "events".id FROM "events" INNER JOIN "memberships" ON "events"."id" = "memberships"."event_id" WHERE "memberships"."user_id" = $1 AND "memberships"."user_id" = $2
In second it has no AND: SELECT "events"."id" FROM "events" INNER JOIN "memberships" ON "memberships"."event_id" = "events"."id" WHERE "memberships"."user_id" = $1
I can't get why this is happening, any guess? Moreover if I change this: @memberships = @user.memberships.available_for(current_user)
To this: @memberships = Membership.available_for(current_user).where(user_id: 1)
It will work as expected as I added join explicitly as above |
| Mantaining an array and some nested form fields consistent? Posted: 07 Dec 2016 07:24 AM PST I'm using cocoon to handle some form fields but I need to use the values of the active form fields elsewhere on the page, specifically on an array that is used elsewhere; so I need to populate the form fields with the array and when one changes, change the other. What I'm currently doing is, whenever the array is modified, I remove all form fields, add them again but then I can't access them by the index and when one is changed I'm unsure how to catch the change and get the actual index modified, given how cocoon handles inserting and deleting, the index isn't consistent with what's shown. |

| Cucumber and Carrierwave - undefined method 'attachment_changed?' Posted: 07 Dec 2016 06:53 AM PST I have a rails 4 app where everything works from the UI, or in the console. When I run the cucumber tests I get this failure: When I sign in with valid credentials # features/step_definitions/user_steps.rb:71 undefined method `attachment_changed?' for #<User:0x007f8ef78cda88> Did you mean? attachment_cache attachment_cache= (NoMethodError) ./app/controllers/application_controller.rb:13:in `set_current_user' ./features/step_definitions/user_steps.rb:43:in `sign_in' ./features/step_definitions/user_steps.rb:73:in `/^I sign in with valid credentials$/' features/sign_in.feature:15:in `When I sign in with valid credentials'
The line in the application_controller is: User.current_user = current_user unless current_user.nil?
Here is the user model: devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable include Archivable mount_uploader :attachment, AttachmentUploader belongs_to :company after_initialize :set_default_role, :if => :new_record? def self.current_user @current_user || User.new(email: 'admin@us.com', first_name: 'admin', last_name: 'User') end def self.current_user=(cur_user) @current_user = cur_user end
If I remove the mount_uploader line, everything works fine. If I test with the console, I can see that carrierwave remaps the attachment attribute to a carrierwave object, thus attachment_changed? is nil instead of false. My question is why is the assignment of current_user triggering a whole dirty check of the model? And, how do I suppress it? |

| Language Redirect 300 without "You are being redirected" Posted: 07 Dec 2016 06:41 AM PST I've found many questions and answers in stack about my problem but they just say that I need to change redirect status to 301 or anything else.

But it waits full loading page and then make redirect. It's awful decision. It works fine except of Google Chrome browser. (maybe all webkit) How can I solve my problem?

| Does ActiveRecord make a new database connection per model Posted: 07 Dec 2016 07:06 AM PST I'm trying to understand how ActiveRecord connects to a database on a per model basis. So lets assume we have 2 models and one database. When you do a simple Model.find on both models does this create a new database connection for each model so it has its own defined connection or is there a single connection to the database that has been initialised that is shared across the 2 models. Does anyone know where it's doing this in the code? I am trying to understand how ActiveRecord achieves this. |

But there doesn't seem to be an environment variable for the prefix, that or i've missed it somewhere along the line. Is this possible, or do you have to find it through some hacky way using the controller & action / route? it's almost as if i'm after a: request.env['PATH_PREFIX']

| Rails 4 - Join Query matches all in array Posted: 07 Dec 2016 07:01 AM PST I have two models, Facility and Category: class Facility < ActiveRecord::Base has_and_belongs_to_many :categories end class Category < ActiveRecord::Base has_and_belongs_to_many :facilities end
Say I have three possible Category records, with name: "Category A", "Category B", and "Category C". I want to get all Facility records which are in both "Category A" and "Category B". My latest query is: Facility.joins(:categories).merge(Category.where(Category.arel_table[:name].matches_all(["Category A", "Category B"])))
which produces the following SQL: SELECT "facilities".* FROM "facilities" INNER JOIN "categories_facilities" ON "categories_facilities"."facility_id" = "facilities"."id" INNER JOIN "categories" ON "categories"."id" = "categories_facilities"."category_id" WHERE ("categories"."name" ILIKE 'Category A' AND "categories"."name" ILIKE 'Category B')
This returns no results. Using pure Ruby (e.g. Facility.all.select ...), I know there is at least one Facility in the database which belongs to both and only both "Category A" and "Category B". How can I perform this query either in Rails or using arel? |

| Rails 5 - first vs where limit 1 vs find Posted: 07 Dec 2016 05:58 AM PST Using Benchmark ips I did this testing. Correct me if I'm wrong in what I just tested. Note that 96 is the id of the first user in my db. Benchmark.ips do |x| x.report("first") do User.first end x.report("where") do User.where(id: 96).limit(1) end x.report("find") do User.find(96) end x.compare! end
I ran this test several times and got this as result Comparison: where: 26430.8 i/s first: 999.8 i/s - 26.44x slower find: 964.3 i/s - 27.41x slower
My conclussion of this is to always use where instead of find or first as these are much slower ways to get a specific user. Rails 5.0.0.1, PostgreSQL 9.5.3, Ruby 2.3.1 |

| Rails time_zone_select to use "official" time zone values Posted: 07 Dec 2016 04:51 AM PST My view (haml): = f.time_zone_select :time_zone, nil, {}, class: 'form-control'
Renders to: ... <option value="Ljubljana">(GMT+01:00) Ljubljana</option> <option value="Madrid">(GMT+01:00) Madrid</option> <option value="Paris">(GMT+01:00) Paris</option> <option value="Prague">(GMT+01:00) Prague</option> ...
When creating a record I want to set the :time_zone attribute to the current time zone of the user. There are several ways to do this but after researching I found either the gem timezone_local or the JS library jstz most common ones. Either way, all those open source libraries seem to use a different pattern then rails does, e.g the Paris timezone is defined as: Europe/Paris However, the TimeZone object in Rails uses Paris this leads to inconsistencies when I want to create a record with the current time zone of the user as it won't match. I need rails to use the same patterns as jstz or vice versa but I don't want to gsub strings here or similiar. What is the best approach here? |
| Rails 4; Stub implementation Posted: 07 Dec 2016 05:22 AM PST Here I'd love to stub some implementation. This is an original one. ActiveRecord::Base.transaction do itemable = create_invoiceitemable(each_line) next unless itemable.present? create_invoiceitem(invoice, itemable, each_line[:id]) end ReceiptMailer.receipt(invoie[:uuid]).deliver_later
config/initializers/stubs.rb ReceiptMailer.prepend(Module.new do def receipt(*args) Logger.info "ReceiptMailer#receipt called with #{args.inspect}" Hashie::Mash.new { deliver_later: nil } # to allow call end end) unless RAILS_ENV[:production]
However deliver_later can not be stubbed somehow, instead it starts looking for Redis connection. (deliver_now with the above way just works perfectly.) Any ideas to work around the Redis connection with those stubbing. |

The problem is that if I try to see the last submission in the console, there is nothing that correlates to the username I chose. Thanks |
