| How to get data out of an $.ajax() call [duplicate] Posted: 02 Dec 2016 07:36 AM PST This question already has an answer here: I am attempting to get a variable from a ruby on rails controller using javascript. I am able to get the data from the controller into my console but I cannot use the variables outside of the functions that get the data. My code: function get_location_calc_level_data(useReturnData) { $.ajax({ method: "GET", url: "/st_location_mgmt/inventory/get_location_calc_level", success: function(data) { useReturnData(data); } }); } var level; get_location_calc_level_data(function(output){ console.log("output: ", output); console.log("output level: ", output.level); level = output; }); var levels = level; console.log("level: ",level) console.log("levels: ",levels)
The console calls return: 2016-12-02 10:27:20.498 VM16344:100 level: undefined 2016-12-02 10:27:20.499 VM16344:101 levels: undefined 2016-12-02 10:27:20.593 VM16344:94 output: Object {level: "full"} 2016-12-02 10:27:20.596 VM16344:95 output level: full
My goal is to use that "level" variable to be used as a flag that will drive behavior in another function $.each() that is called after this code |
| Sidekiq and unqueueing in ruby Posted: 02 Dec 2016 07:05 AM PST I am currently enabling queueing in on of my app wrote in Ruby. I use sidekiq and have define a worker class as below: class Worker include Sidekiq::Worker def perform(params) sleep 10 @@logger.info("--------------------------") @@logger.info("Request received") @@logger.info("--------------------------") end end
I am calling it from my main entry point called 'api.rb' post '/receive/?' do @@logger.debug("/retrieve endpoint received") Worker.perform_async @params end
this working fine and each time the sleep is done, the next queued task is started. In my case, I need to unqueued or start the next item queued only when I decide it. it will be triggered by an external event. in my 'api.rb', I have added: post '/response/?' do next_task end
The way the code works is that '/receive' can queued 10 requests. the first request will triggered a specific action (sent a post command to a server). I expect the remote server to send me back a request through '/response' to tell me that the action is finished. when this response is received, I use the 'next_task' api to remove the previous task which was running and now completed and move to the next queued one. Any idea, how to create a custom trigger to unqueue and start the new job. Is there SIGNAL which allow me to avoid the sidekiq framework to unqueue until I send a specific signal. Merci |

| wicked_pdf only partially uses bootstrap Posted: 02 Dec 2016 06:49 AM PST I'm generating a PDF in Rails using wicked_pdf. I've followed instructions on their wiki about how to include Bootstrap but with only partial success. I've also seen answers on here, but also without perfect results. In debug mode, everything looks fine. But the PDF is missing background colours using helpers like .bg-danger and striped tables. However I have got the correct typography, layout/column helpers and things like .img-responsive. Also, the page numbers don't work; I'm not sure if that's related or not. controller extract respond_to do |format| format.html do render :template => "report/report.html" end format.pdf do render pdf: "report", template: 'report/report.html', layout: 'pdf', show_as_html: params[:debug].present?, footer: { right: '[page] of [topage]' }, javascript_delay: 2000, page_size: 'A4', viewport_size: '1280x1024'

| Rails Active Record cancel save or create in before_create without raising exception Posted: 02 Dec 2016 06:44 AM PST Actually, I want to test a model callback. system_details.rb (Model) class SystemDetail < ActiveRecord::Base belongs_to :user attr_accessible :user_agent before_create :prevent_if_same def agent Browser.new(ua: user_agent, accept_language: 'en-us') end def prevent_if_same rec = user.system_details.order('updated_at desc').first return true unless rec if rec.user_agent == user_agent rec.touch return false end end end
prevent_if_same method is working fine and working as expected but it raises exception ActiveRecord::RecordNotSaved when it returns false, and the exception breaks the rspec test.what I want is, It should silently cancel save without raising an exception.
system_detail_spec.rb (rspec) require 'rails_helper' RSpec.describe SystemDetail, :type => :model do context '#agent' do it 'Checks browser instance' do expect(SystemDetail.new.agent).to be_an_instance_of(Browser) end end context '#callback' do it 'Ensure not creating consecutive duplicate records' do user = create :end_user system_detail = create :system_detail, :similar_agent, user_id: user.id updated_at = system_detail.updated_at system_detail2 = create :system_detail, :similar_agent, user_id: user.id system_detail.reload expect(system_detail2.id).to be_nil expect(system_detail.updated_at).to be > updated_at end end end
The 2nd test #callback was failing because of exception. Failures: 1) SystemDetail#callback ensure not creating duplicate records Failure/Error: system_detail2 = create :system_detail, :similar_agent, user_id: user.id ActiveRecord::RecordNotSaved: ActiveRecord::RecordNotSaved Is there any way to silently cancel save without raising an exception? |

| Add custom class to simple_form_for association of type option - Rails Posted: 02 Dec 2016 05:45 AM PST I'm using a simple_form_for with a association = f.association :type, :collection =>version_name,:label => "Application type:", :selected =>'', :item_wrapper_class => 'lbl_type'
This generates a html like below, <div class="control-group select optional"> <label class="select optional control-label" for="subscription_type_id">Application type:</label> <div class="controls"> <select class="select optional control-label" id="subscription_type_id" name="subscription[type_id]"> <option value="4">Type 1</option> <option value="5">Type 2</option> </select> </div> </div>
I tried with item_wrapper_class but it is not working How to add specific custom classes to the control-label and to the input field Is there any way I can achieve this? |

| Rails re-formatting my datetime Posted: 02 Dec 2016 05:14 AM PST I have a big query, which collects a collection of models, and I need to format the timestamps in the following manner: YYYY-MM-DDTHH:MI:SS.MSZ So, my query looks like: models.select("(to_char(created_at, 'YYYY-MM-DD') || 'T' || to_char(created_at, 'HH24:MI:SS.MSZ')) AS created_at").as_json
But, when I get the result, I still get created_at field as a DateTime object. Nevertheless, if I rename the field in something else, like AS something_else, then I have my required format. How can I fix the problem, so that it will return created_at in my format, without going through the whole collection, and formatting each model ? UPDATE Database I am using is PostreSQL I traced this behaviour back to ActiveSupport::JSON::Encoder. I use the gem activesupport-json_encoder because I need the setting ActiveSupport.encode_big_decimal_as_string = false, while since Rails 4.1 they by default are encoded as strings. Now, this Encoder is encoding created_at and updated_at fields as ActiveSupport::TimeWithZone. Can I get rid of the latter somehow ? |
| Rails - Confirmation of numeric attributes Posted: 02 Dec 2016 04:14 AM PST I've been trying Ruby on Rails for a few months now, re-engineering a desktop application. This application has a form for updating take-off and landing points, whose coordinates must be confirmed. Well, I tried validates_confirmation_of method however it works only with String attributes, and I have Integer and Decimal types. Hence I created an alternative method by borrowing an excerpt from the helper (confirmation.rb), which is working fine. But I wonder if there is another way to do it or whether this solution can be improved. Below follows a compact version of the source files. Thanks in advance! Migration: class CreateWaypoints < ActiveRecord::Migration[5.0] def change create_table :waypoints do |t| t.string :name t.integer :latitude_in_degrees t.integer :latitude_in_minutes t.decimal :latitude_in_seconds, precision: 5, scale: 2 t.timestamps end add_index :waypoints, [:name], unique: true end end
View: <%= simple_form_for(@waypoint) do |f| %> <%= f.error_notification %> <div class="form-inline"> <%= f.input :name %> </div> <div class="form-inline"> <%= f.input :latitude_in_degrees %> <%= f.input :latitude_in_minutes %> <%= f.input :latitude_in_seconds %> </div> <div class="form-inline"> <%= f.input :latitude_in_degrees_confirmation, as: :numeric, label: false %> <%= f.input :latitude_in_minutes_confirmation, as: :numeric, label: false %> <%= f.input :latitude_in_seconds_confirmation, as: :numeric, label: false %> </div> <div class="form-actions"> <%= f.button :submit %> </div> <% end %>
Model: class Waypoint < ApplicationRecord ... validates_each :latitude_in_degrees, :latitude_in_minutes, :latitude_in_seconds do |record, attribute, value| if record.send("#{attribute}_changed?") confirmed = record.send("#{attribute}_confirmation") confirmed == nil ? confirmed = 0 : confirmed = confirmed.to_d.round(2) # 2 matches migration. if confirmed != value human_attribute_name = record.class.human_attribute_name(attribute) record.errors.add(:"#{attribute}_confirmation", "Doesn't match #{human_attribute_name}") end end end end

| Rails - Are saving params in sessions a generally good idea for multistep forms? Posted: 02 Dec 2016 05:34 AM PST I'm generally new to Rails but have a decent understanding of MVC Architecture. With a Multistep form, I have been saving my params to my session and at the end of the multistep form pulling the values from the session and saving to my db. I want to save the data at the end of the multistep, not throughout the journey. An Example :- Form 1 Controller session[:user_details] = params
Form 2 Controller @orders = Order.new @orders.first_name = session[:user_details]['first_name'] @orders.last_name = session[:user_details]['last_name'] @orders.save!
Is this approach the best method given the scenario, or is there an alternate method in ruby which would be clearer? |

Now the problem is it is not finding my data which exists in database. When i put new data then it works fine but only when I need to update or show that data on user requirement. Then it says record not found but at the same time the new input data can be put into data base as I told you before. |

| Create a model association where the model is not a active record model rails Posted: 02 Dec 2016 05:58 AM PST I have a model called Client. This extends not from ActiveRecord::Base but from my own wrapper class. These objects are not stored in my own database. I have some other models called Answer and Device for example. These are stored in my database with a client_id. Now, what I want to do is that is can call Answer.client and Client.answers for example. The normal way would be with ActiveRecord associations but that doesn't work is this case. I can define my own .answers and .client method but in my opinion that's not the way to go with Rails. Thanks in advance for replying! |
| Rails. Test validation of picture size Posted: 02 Dec 2016 04:46 AM PST I have validation in my model, validate :picture_size, my model: class Post < ApplicationRecord belongs_to :user default_scope -> { order(created_at: :desc) } mount_uploader :picture, PictureUploader validates :content, presence: true, length: { maximum: 50_000 } validates :theme, presence: true, length: { minimum: 3, maximum: 100 }, uniqueness: { case_sensitive: false } validates :picture, presence: true validate :picture_size def to_param random_link end private def picture_size return unless picture.size > 5.megabytes errors.add(:picture, 'Файл должен быть меньше, чем 5МБ') end end
My uploader: class PictureUploader < CarrierWave::Uploader::Base include CarrierWave::MiniMagick process resize_to_limit: [600, 300] storage :file def default_url ActionController::Base.helpers.asset_path("default/no-photo-wide.png") end def store_dir "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end def extension_white_list %w(jpg jpeg gif png) end end
And it works well when I run rails server. But I wrote couple of tests, and it really somehow avoid validation and upload picture to my store dir. My test: let(:large_image) { Rack::Test::UploadedFile.new(File.open(File.join(Rails.root, '/spec/images/large-image.jpg'))) } it 'will give error if picture is more then 5mb' do post = Post.new(theme: 'foo', content: 'bar) post.picture = large_image post.save puts Post.first.picture expect(post.valid?).to be false end
But result is true, not false. Can some tell where I made my mistake or suggest any other way to test picture size validation? |
| Reporting in Rails with LaTeX using Models Posted: 02 Dec 2016 02:33 AM PST I would like to give my users the ability to create their own (PDF) reports in my Rails App. I think, the best way to accomplish that, is to use LaTeX, because it give a really nice output and many options to the user. Is there any Gem which i can use for that? Ruby-Toolbox give me some Gems - for example Rtex or rails-latex, but they doesnt seem to work with models (i would like to use a content field for the latex-erb stuff from my database). The only Gem i could find is ArTeX, which seems to be abandoned and not documented. Is there any better Gem for my purpose or is there any way i could use Rtex/rails-latex with my model-content? |

| How can I correctly test in minitest that, on a bad path for a method call, a notification service gets called? Posted: 02 Dec 2016 02:17 AM PST I am quite a newbie on minitest and I need help! My environment, to begin with, is: rails (4.2)minitest (5.9.1) as test frameworkmocha (1.2.1) as mock framework Let's say that I have this Job class: class GapCreationJob < ActiveJob::Base queue_as :default rescue_from ActiveRecord::RecordNotFound, StandardError do |error| handle_error(error) end def perform(gbu_id) # some code that might raise an exception... end private def handle_error(error) msg = "my message" Rollbar.warn(msg) Rails.logger.error "#{msg}\n Detail: #{error.message}" end end
How should I write a test that checks that - in case of exception - the Rollbar.warn gets called? My problem, as newbie, is to write the expectation on the Rollbar class. I've tried this, but it does not work: require "test_helper" class GapCreationJobTest < ActiveJob::TestCase setup do # code that sets up @import @import = ... Rollbar = mock('rollbar') end test "a completely failing import job should notify us on rollbar" do GuestBusinessUnit.any_instance.expects(:set_activities_all).raises(ActiveRecord::RecordNotFound) GapCreationJob.any_instance.expects(:handle_error) # this works, but it is not sufficient Rollbar.expects(:warn) # this expectation is not satisfied, even if - on the testing class - the real Rollbar.expects method gets called GapCreationJob.perform_now(@import.id) end end
Here is the output when I run this test: > rake test:jobs Running via Spring preloader in process 27705 Started with run options --seed 62075 GapCreationJobTest test_create_guest_activity_plans_after_guest_business_unit_creation PASS (1.42s) ~/Development/proj/test/jobs/gap_creation_job_test.rb:9: warning: already initialized constant GapCreationJobTest::Rollbar ~/Development/proj/test/jobs/gap_creation_job_test.rb:9: warning: previous definition of Rollbar was here test_a_completely_failing_import_job_should_notify_the_creator FAIL (0.02s) Minitest::Assertion: not all expectations were satisfied unsatisfied expectations: - expected exactly once, not yet invoked: #<Mock:rollbar>.warn(any_parameters) satisfied expectations: - expected exactly once, invoked once: #<AnyInstance:GuestBusinessUnit(id: integer, guest_id: integer, business_unit_id: integer, status: integer, datein: date, dateout: date, created_at: datetime, updated_at: datetime, idospite: string, conv_struttura: string, created_who: integer, updated_who: integer)>.set_activities_all(any_parameters) - expected exactly once, invoked once: #<AnyInstance:GapCreationJob>.handle_error(any_parameters) test/jobs/gap_creation_job_test.rb:22:in `block in <class:GapCreationJobTest>'

Now in Services::My (app/services/my.rb), I have a reference to one of the following (no need to distinguish, since the behaviour is exaclty the same in all situations): Deeply::Nested::DogServices::My::Deeply::Nested::Dog::Services::My::Deeply::Nested::Dog No matter which of the above I choose, I always get the following error message: services/my.rb: warning: toplevel constant Dog referenced by Services::My::Deeply::Nested::Dog Also, my deeply nested Dog never even gets seen by the interpreter (I found out by using puts and syntax errors, nothing happens). Possible workarounds (which I all don't like) are: - Rename one of the Dog classes
- Run with RAILS_ENV=production in order to disable autoloading and use eager loading instead
require_dependency that points to the deeply nested dog As a computer scientist, I find none of the above workarounds satisfactory. I would like to understand why my deeply nested Dog is not found without workaround and find out what the state-of-the-art Ruby / Rails solution would be for this problem. Thanks a lot in advance. |
