| rails 5 mysql adapter issue Posted: 06 Aug 2016 07:38 AM PDT Am trying to create a model in rails 5 and have installed mysql-community-server. Also I have installed both mysql and mysql2 gem's.

| Convert instance object into JS object in "view" in order to assign into data- html attribute cuts off in middle Posted: 06 Aug 2016 07:19 AM PDT I am looping instance variable "@packages" set in controller and am trying to assign single object into one of the html element by using "data-". For changing ruby object into json i am using ".to_json" as follows: <% @packages.each do |package| %> <% json_package=package.to_json %> <a href="#" data-single-package=<%= json_package %>></a> <% end %>
However, on inspecting the anchor tag i found json object is cutting off in one of the property which had a value with space in between it. 
As you can see, "title" property has value "annarpurna circuit", but ".to_json" is cutting off in space by adding ". How can i make this whole string pass through?? |

| Getting uniqueness on multiple model association Posted: 06 Aug 2016 07:16 AM PDT There are three models: # Table name: activities_people # # activity_id :integer not null # person_id :integer not null # date :date not null # id :integer not null, primary key # # Table name: activities # # id :integer not null, primary key # name :string(20) not null # description :text # active :boolean not null # day_of_week :string(20) not null # start_on :time not null # end_on :time not null
Third model is people. Associations: class Activity < ActiveRecord::Base has_many :activities_people has_many :people, through: :activities_people end class ActivitiesPerson < ActiveRecord::Base belongs_to :person belongs_to :activity end class Person < ActiveRecord::Base has_many :activities, through: :activities_people end
Issue: I don't know how to create validation method in ativities_person.rb to protect joining on activities, that overlaps timely. Example: person_id:1 join to activity, that will 08.08.2016(date) and last 09:00(start_on) - 10:00(end_on). Same person want save to another activity, that will also be 08.08.2016 and last 09:30(start_on) - 10:30(end_on). Now validation should throw error that he's save to other activity in same time(time ranges overlap). Validation first should check that dates match, next should check time overlaps of activities. What I tried: def check_join_client # check if client joined to some activities in same date as current join activities_date = person.activities_people.where(date: date) if activities_date.any? # get start_on and end_on for current activity and date get_activities = person.activities.where(id: activities_date.pluck(:activity_id)) ol_activities = get_activities.where('((start_on <= :start_on AND end_on >= :end_on) OR (start_on <= :start_on AND end_on <= :end_on AND end_on >= :start_on) OR (start_on >= :start_on AND start_on <= :end_on AND end_on >= :end_on))', start_on: get_activities.pluck(:start_on), end_on: get_activities.pluck(:end_on)) end end

In both _youtube.slim and _custom.slim I just call smth like p = provider.name. Moreover, "custom' was created by copy-pasting code from 'youtube'. However, while rendering Rails throws an error: undefined local variable or method 'provider' for #<#<Class:0x00564028bb89d8>:0x007f92d3d0fa80> Trying to resolve this issue I just renamed _custom.slim to _custom1.slim and changed a call to = render partial: 'custom1', locals: { provider: restream.provider} and that worked! Can anyone, please, explain, how does it works and what's wrong with 'custom' name? Is it a reserved name? |
| Rails: missing indexes when converting sqlite file into postgres db with pgloader Posted: 06 Aug 2016 06:07 AM PDT For my rails application, I'm converting a local sqlite3 file into a postgres database with pgloader. To do this, I created a postgres database createdb my_database_development
and I create a pgload command file load database from 'db/production.sqlite3' into postgresql:///my_database_development with include drop, create tables, create indexes, reset sequences set work_mem to '16MB', maintenance_work_mem to '512 MB';
Now loading the sqlite file into the postgres db works, and I don't think I have any errors. All tables and records are copied, but when I look in my rails application, none of the records have an index (or id). Here is the output of loading the sqlite file into the database simon (master *) Blog-database $ pgloader db/development.sqlite3 postgresql:///my_database_development 2016-08-06T13:57:41.201000+03:00 LOG Main logs in '/tmp/pgloader/pgloader.log' 2016-08-06T13:57:41.222000+03:00 LOG Data errors in '/tmp/pgloader/' 2016-08-06T13:57:41.425000+03:00 WARNING Postgres warning: table "schema_migrations" does not exist, skipping 2016-08-06T13:57:41.626000+03:00 WARNING Postgres warning: table "comments" does not exist, skipping 2016-08-06T13:57:41.627000+03:00 WARNING Postgres warning: table "users" does not exist, skipping 2016-08-06T13:57:41.627000+03:00 WARNING Postgres warning: table "pictures" does not exist, skipping 2016-08-06T13:57:41.828000+03:00 WARNING Postgres warning: table "posts" does not exist, skipping table name read imported errors time ---------------------- --------- --------- --------- -------------- fetch 0 0 0 0.001s fetch meta data 8 8 0 0.050s create, truncate 0 0 0 0.343s ---------------------- --------- --------- --------- -------------- schema_migrations 12 12 0 0.068s comments 23 23 0 0.014s users 3 3 0 0.064s pictures 24 24 0 0.069s posts 4 4 0 0.055s index build completion 0 0 0 0.014s ---------------------- --------- --------- --------- -------------- Create Indexes 4 4 0 0.312s Reset Sequences 0 0 0 0.064s ---------------------- --------- --------- --------- -------------- Total streaming time 66 66 0 0.742s

There is no jobs in the queue and when I test my app's email notification the job seems to be processed fine. Is this normal? It seems to be repeating frequently and adding to the log file. I do have logrotate setup but unsure if it's a configuration I did or miss to cause this. Thanks for shedding some light into this. |

| Rails - Trying to pass param via AJAX to Devise sessions#new action to pre-populate email attribute Posted: 06 Aug 2016 02:23 AM PDT I have this line in my javascript: $.ajax({url: '/users/sessions/new?user_email=' + userEmail});
and I have this code in ~/app/controllers/users/sessions_controller.rb: def new @user_email = params[:user_email] super end
and in ~/config/initializers/devise.rb I have: config.scoped_views = true
and I have this in ~/app/views/users/sessions/new.html.haml: %h2 Sign In .sign-in-form-wrapper = simple_form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| .form-inputs = f.input :email, required: true, value: @user_email, readonly: true = f.input :password, required: true, autofocus: true = f.input :remember_me, as: :boolean if devise_mapping.rememberable? .form-actions = f.button :submit, "Sign In" = render 'users/shared/links'
If I output the value of @user_email in the new action, I get the correct value that I'm passing. But within the new action, after @user_email is assigned the value and it hits super, nothing happens. The sign in form isn't rendered and I can't figure out why. I'm seeing this in the log: INFO -- : Started GET "/users/sign_in?user_email=b.wayne@gotham.com" for 127.0.0.1 at 2016-08-06 02:13:58 -0700 INFO -- : Processing by Users::SessionsController#new as */* INFO -- : Parameters: {"user_email"=>"b.wayne@gotham.com"} INFO -- : Rendered users/shared/_links.html.haml (0.5ms) INFO -- : Rendered users/sessions/new.html.haml within layouts/application (14.5ms)
Is there something about it being processed as */*? Should it be html? And if so, why would it not be? Thanks in advance for any insight that can be provided. |

| Searchkick aggregations Posted: 06 Aug 2016 12:43 AM PDT I have the following two aggregations in Rails using searchkick gem. When I used any of them separately, it works like a charm. But I want to "merge" them together and cannot figure out how to do it :(. Aggregation 1: aggs: { price_vat: { ranges: [{to: 5}, {from: 5, to: 10}, {from: 10}] } }
Aggregation 2: aggs: ['property_options.property_id', 'property_options.id', 'property_options.value_cs', 'property_options.value_en', 'manufacturer_id']
Is there any expert on this who knows how to do it? Really appreciated. Thank you and have a good weekend, Miro. |
| facebook could not retrieve data from url in rails app Posted: 06 Aug 2016 12:25 AM PDT I am working on this rails web application where I have implemented facebook link share for some of the urls. It seems to be working fine for most of them like eg: travelibro.com, travelibro.com/destinations, travelibro.com/destinations/germany, travelibro.com/blog/interview-with-a-wanderer-steph-parker, travelibro.com/monish-shah/journeys/bangalore-day-trip-2149.

| how to do different alerts in different sides of the channel in private_pub? Posted: 06 Aug 2016 12:03 AM PDT I am trying to write a chat application in rails using private_pub gem, I have set up almost everything, but I have a problem showing different things in different sides, the simplified question is this: I want to show 2 different alerts in each side, that is for example when the form is submitted, in the sender side I want to have alert("x"); and in the recipient side I want to have alert("y"); But I always get this 
I am also using devise gem, but when I use current_user.id to make a decision it always returns the user who submitted the form. it seems a same thing is always happening in both sides, I wonder how can I do different things there? |
| Where does hamburger jquery button code go in Rails 4? Posted: 05 Aug 2016 10:20 PM PDT I have a hamburger button that causes a sidebar to appear and disappear. I'm using rails and jquery. I have included the gem jquery-rails. application.js //= require jquery //= require jquery_ujs //= require turbolinks //= require_tree .
When I include the code directly in my view as: <script> $('.hamburger').on('click', function () { if ($('.sidebar').hasClass('open')) { $('.sidebar').removeClass('open'); } else { $('.sidebar').addClass('open'); }}); </script>
it works! When I take away the script and put it in my xxx.coffee file which I've renamed to xxx.js, it doesn't work. I looked at the webpage code and have <script src="/assets/xxx.self-numbersandletters.js?body=1" data-turbolinks-track="true"></script>
I can't put together where I'm making a mistake. I think it might be that it comes together like: <script $('.hamburger').on('click', function () { if ($('.sidebar').hasClass('open')) { $('.sidebar').removeClass('open'); } else { $('.sidebar').addClass('open'); }});> </script>
but I guess I have to read more about the asset pipeline or convert it to coffee script. |

| Get id for nested MVC? Posted: 06 Aug 2016 12:25 AM PDT <%= @dueler.id %> is showing the wrong integer. For example, duel has two duelers 34 and 35. The current_user is 78, which dueler 34 is user 78.
By making sure the current_user is a dueler of the duel then he will be empowered to update his dueler status. duels/show Duel <%= @duel.id %> = 20 Dueler <%= @dueler.id %> = 10 # How to get 34 instead? User <%= current_user.id %> = 78
rails c pry(main)> Dueler.last id: 34, # This is what it should say since 78 is the current_user user_id: 78, challenge_id: 295, duel_id: 20, accept: nil> pry(main)> Dueler.last id: 35, user_id: 150, challenge_id: 290, duel_id: 20, accept: nil> pry(main)> Duel.last id: 20, consequence: "TEST", reward: "TEST", created_at: Fri, 05 Aug 2016 21:38:31 EDT -04:00, updated_at: Fri, 05 Aug 2016 21:38:31 EDT -04:00>
duels_controller def show @duel = Duel.find(params[:id]) @duelers = Duel.duelers.find(params[:id]) # What should this be instead? end
I thought maybe something like this would work: def show @duel = Duel.find(params[:id]) @duelers = Duel.duelers.find(params[:id]) # Get hash of duelers i.e. 34 & 35 @dueler = @duelers.find(current_user = Dueler.user_id) # If current_user is equal to the user_id of dueler then that dueler is thee dueler, i.e. 34 end

| ActiveModel::ForbiddenAttributesError When Creating New `Task` Posted: 05 Aug 2016 09:22 PM PDT I am getting an ActiveModel::ForbiddenAttributesError when trying to create a new task. I think I have eliminated all of the stupid errors, so I would love help figuring it out. My tasks_controller is as follows: class TasksController < ApplicationController def index @tasks = current_user.Task.all end def create @task = Task.new(params[:task]) <<<<<<<<<<<THIS LINE @task.user = current_user if @task.save flash[:notice] = "Your exercise results were saved!" redirect_to tasks_path else render :action => 'new' end end def new @task = Task.new end def edit @task = Task.find(params[:id]) end def update @task = Task.find(params[:id]) if @task.update_attributes(params[:task]) <<<<<<<<<<<THIS LINE redirect_to tasks_path end def destroy @task = Task.find(params[:id]) @tasks.destroy redirect_to tasks_path end def show @task = Task.find(params[:id]) end private def task_params params.require(:task).permit(:name, :reps, :weight, :comments, :user_id) end end end
On the two indicated lines I have tried both params[:task] and 'task_params'. The first throws up the ForbiddenAttributesError; the latter throws up undefined local variable or methodtask_params' for #`. Here's my tasks#new erb: <%= form_for @task do |f| %> <div class="col-xs-12"> <%= f.label "Exercise Name" %> <%= f.text_field :name, class: "form-control" %> </div> <div class="col-xs-6"> <%= f.label "Reps" %> <%= f.number_field :reps, class: "form-control" %> </div> <div class="col-xs-6"> <%= f.label "Weight" %> <%= f.text_field :weight, class: "form-control" %> </div> <div class="col-xs-12"> <%= f.label "Comments/Notes" %> <%= f.text_field :comments, class: "form-control" %> </div> <div class="text-center"><%= f.submit "Record Exercise", class: "btn-primary" %></div> <% end %>
Finally, my schema for tasks is as follows, so I know the names of the variables are right: create_table "tasks", force: :cascade do |t| t.string "name" t.integer "user_id" t.integer "reps" t.integer "weight" t.text "comments" t.datetime "created_at", null: false t.datetime "updated_at", null: false end
Can anyone guide me in fixing this "the Ruby way"? |
