| Trying to validate that an array is not blank in rails [on hold] Posted: 12 Jan 2017 08:19 AM PST I am trying to validate that at least one entry was chosen in a rails dropdown that populates an array. In my model, I have validate :operators_chosen def operators_chosen if (:operators.count <= 1) errors.add(:operators, "must choose at least one") end end
But that gives me NoMethodError in SlitterBedsheetsController#create undefined method `count' for :operators:Symbol Rails.root: C:/Users/cmendla/RubymineProjects/slitter_bedsheets Application Trace | Framework Trace | Full Trace app/models/slitter_bedsheet.rb:22:in `operators_chosen' app/controllers/slitter_bedsheets_controller.rb:148:in `block in create' app/controllers/slitter_bedsheets_controller.rb:147:in `create' Request Parameters: {"utf8"=>"✓", "authenticity_token"=>"0TLaXfnuS3r4nUbMSg3Bt+svvwJPvPioCA8s/L++TqbG79l2lZamfl18thD/yzrBao63TRDmgy58TbqA3D42kw==", "slitter_bedsheet"=>{"machine_number"=>"SL-3", "shift"=>"B", "start_time(1i)"=>"2017", "start_time(2i)"=>"1", "start_time(3i)"=>"12", "start_time(4i)"=>"11", "start_time(5i)"=>"12", "date(1i)"=>"2017", "date(2i)"=>"1", "date(3i)"=>"12", "operators"=>["", ""]}, "commit"=>"Create Slitter bedsheet"}
I believe that I can validate that at least one operator was chosen by checking that the array count was 1 or greater. Can I modify the code I have here or is there another way to do it? I tried .present? and !....null? but couldn't seem to make them work. |
| Rails create list of items based on DB field Posted: 12 Jan 2017 08:17 AM PST In my Rails application I have a Kid model with different allergy fields labeled allergy_one, allergy_two, allergy_three, etc. I want to create a list in my controller called @allergies in order to create a list of items containing Kid's that have at least one allergy. Some kids have 4 allergies where as some only have 1. I want to be able to use this list in my index to iterate over @allergies in a manner that Kid's name may be listed multiple times, but each of allergy_one, allergy_two, etc. is listed only once. Here is an example of table I would want displayed: |------------|-------------| | Name | Allergy | |------------|-------------| | Marco | Nuts | | | | | Tim | Dust | | | | | Tim | Cashews | | | | | John | Milk | |------------|-------------|
As you see the main model is Kid and it has fields for allergy_one, etc. What I have for allergies so far is: @allergies = Kid.where("allergy_one is NOT NULL") What I need direction for is how I can arrange code in my index.html to display each allergy. All help is appreciated, thanks!

| Add class to bootstrap_form_for collection_select in Rails 5 Posted: 12 Jan 2017 07:59 AM PST I use bootstrap_form_for to create forms and have a collection select, where I want to add a custom class. I tried this, but this does not work: <%= f.collection_select :location, Location.all, :id, :name, label: 'Location', :include_blank => ("Select..."), hide_label: true, :class => 'location' %>
Any ideas? |
| Rails, Mongoid, using environment variable for database config throws NoMethodError Posted: 12 Jan 2017 08:00 AM PST I'm trying to deploy my rails application, which uses mongoid, to my remote production server. In my mongoid.yml I have added this: hosts: - <%= ENV['MONGOSERVER_PORT_27017_TCP_ADDR'] %>:27017
When I launch my capistrano, it throws me this error: SSHKit::Command::Failed: rake exit status: 1 rake stdout: rake aborted! NoMethodError: undefined method `split' for :"27017":Symbol
Does that adding underscores makes this error happen? |

| How to get current_user in Rails using devise_token_auth? Posted: 12 Jan 2017 08:12 AM PST I use devise_token_auth with devise for auth and registration. Everything goes well: I can sign in, sign out using api and web interface. But I can't get current_user devise variable (nil). <% if current_user %> <%= link_to "Edit profile", edit_user_registration_path(current_user.id) %> | <%= link_to('Logout', destroy_user_session_path, :method => :delete) %> <% else %> <%= link_to "Register", new_user_registration_path %> | <%= link_to('Login', new_user_session_path) %> <% end %>
application_controller.rb class ApplicationController < ActionController::Base include DeviseTokenAuth::Concerns::SetUserByToken protect_from_forgery with: :null_session, if: Proc.new { |c| c.request.format == 'application/json' } end
I need this variable as a global for using, for example, in application.html.erb |
