| How can I see my uploaded images? Posted: 11 Sep 2016 07:50 AM PDT Ruby version 2.2.4 Rails version 5.0.0.1 Hello people I am a totally beginner in RoR and after long hours I finally uploaded an picture from my android app to ruby on rails.

| How to use Chartkick and mapping line graphs Posted: 11 Sep 2016 06:11 AM PDT I am currently using Chartkick to make a line graph that is plotting the progress of a profit and loss chart with individual bets. Currently I have the graph correctly outputting a graph with a profit and loss while the bets are grouped by the day on which they were placed with the following code <%= area_chart @bets.group(:created_at).sum(:profit_or_loss).map { |x,y| { x => (@sum += y)} }.reduce({}, :merge), xtitle: "Date", ytitle: "Units" %>
However I am looking to change this so that the graph plots per 50 entries or 100 entries. I am unsure of the correct syntax to group it this way as my understanding is that the id of each entry is not a class. This is the schema for the entry database. create_table "bets", force: :cascade do |t| t.string "game" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.string "bet_placed" t.decimal "profit_or_loss", default: 0.0 t.date "date_of_bet", default: '2016-03-11' t.decimal "odds", default: 0.0 t.decimal "units_placed", default: 0.0 t.boolean "push", default: false t.boolean "resolved", default: false t.integer "bookmaker" t.integer "sport" end

| Rails form won't submit after adding Foundation Posted: 11 Sep 2016 05:02 AM PDT I added the Foundation-Rails gem to my app and now my form won't submit. There are no errors in the console, and it's triggering a new event, but instead of adding it to the database, it puts the form submission information into the URL bar. So, it looks like this: http://localhost:3000/submissions/new?utf8=%E2%9C%93&authenticity_token=T9qweZClsZHL%2B6hzepcz%2BipG4W5p5VEzxO9PcB7FJ%2F6lun8wHVbvtGRe8JZC1rqay5DEMCm%2F06RzQh91G6cRGA%3D%3D&submission%5Bsubmission_link%5D=test&submission%5Blocation%5D=test&submission%5Bbedrooms%5D=0&submission%5Bbathrooms%5D=0&submission%5Bimg1%5D=asdf&submission%5Bimg2%5D=asdf&submission%5Bimg2%5D=asdf&commit=Create+Submission

My problem is i dont know what pass to the :eq method, since i cannot access let variables without exception: `payment` is not available on an example group (e.g. a `describe` or `context` block).

So i cannot hardcode correct results. How can i access these variables in the describe block? |
| Rails 5, Passing variable to partial with ajax Posted: 11 Sep 2016 04:16 AM PDT I'm new at rails and I'm trying to pass a variable through AJAX to a partial. First I create a new pedido and then I make an Ajax call to bring some info from the DB. With that Info I need to select a field and save it into the new pedido. Here is the html for the new pedido page: #new.html.erb <%= form_for @pedido do |f| %> <div id="Cliente"> <%= render 'cliente', f: f %> </div> <% end %>
Now in the pedido controller I have: #pedido_controller.rb def new @pedido = Pedido.new end def get_cliente @cliente = User.find(params[:cliente_id]) respond_to do |format| format.js { render 'get_cliente', layout: false} end end
I make the Ajax call: #pedidos.coffee jQuery -> $(document).ready -> $("#pedido_id").on "change", -> $.ajax url: "/pedidos/get_cliente" type: "GET" data: cliente_id: $('#pedido_id option:selected').val()
My JS file: #get_cliente.js.erb $('#Cliente').html( "<%=j render('cliente', :locals => {:cliente => @cliente, :f => f }) %>" ); $('#Cliente').slideDown(350);
And finally my partial has this line: #cliente.html.erb <%= f.collection_select(:id, @cliente.user_sucursals.all, :id, :nombre, {include_blank: true}, {:class => "form-control"}) %>
So I'd like to save the id from my f.collection_select in _clientes to my new @pedido variable, but I don't know how to assign @pedido variable to my f local in _cliente. If I take out the line in cliente.html.erb everything works, but I need to add that info to my model. Thanks in advance!! |

| Rails code block in controller for repeated code Posted: 11 Sep 2016 07:38 AM PDT In my Rails application I am using the odf-report gem to generate reports. However I have an if condition in my method with the same 110 lines of code in each clause with one or two changes at the end. I am wondering if there is a way to define the 110 lines that are being repeated in a code block and just call that code block in my main method? Below is a sample of the method: def print_enrolment_form_completed kid = Kid.find(params[:id]) if kid.not_anaphylactic? report = ODFReport::Report.new("#{Rails.root}/app/reports/Student_Enrolment_Completed.odt") do |r| #same 110 lines of code end else report = ODFReport::Report.new("#{Rails.root}/app/reports/Student_Enrolment_Completed.odt") do |r| #same 110 lines of code end end end
My goal is to just yield a code block where the comment is listed above and have the 110 lines defined elsewhere in the controller. Any ideas are appreciated! |

| Rails custom model method in where query Posted: 10 Sep 2016 10:41 PM PDT In my rails app I have defined in the Kid model a calculation based on the fields from the Kids DB. the method is as follows: def flip_date self.dob.advance(months: 10) end
I want to use this in my controller as I have a method where I am defining something as follows: new_kids = Kid.where(discharge_date: nil).where('flip_date > ?', Date.current.advance(year: 1).beginning_of_year)
However I keep getting the following error: SQLite3::SQLException: no such column: flip_date: SELECT "kids".* FROM "kids" WHERE "kids"."discharge_date" IS NULL AND (flip_date < '2017-01-01')
Any ideas on how can I make this work? All help is appreciated! |
| How to handle missing dependencies of belongs_to relationship? Posted: 10 Sep 2016 09:58 PM PDT I have 4 models User, Flavor, IceCream and Order User.rb class User < ActiveRecord::Base has_many :orders ... end
flavor.rb class Flavor < ActiveRecord::Base has_and_belongs_to_many :ice_creams ... end
IceCream.rb class IceCream < ActiveRecord::Base has_and_belongs_to_many :flavors ... end
Order.rb class Order < ActiveRecord::Base belongs_to :user has_many :ice_creams .. end
Lets assume that I need to -as an admin- to delete a User that had previously created several orders without deleting those orders from the database. Then when I try to Index orders I come up with an error as the user_id is missing NoMethodError in Orders#index undefined method `first_name' for nil:NilClass <td><%= order.user.first_name + " " + order.user.last_name %></td>
And this thing of course would happens if I deleted a Flavor that already have been used to create an IceCream. Any way I found a temporary solution to avoid the error messages that would put a question mark in case the user is missing <td><%= order.user.present? ? order.user.first_name + " " + order.user.last_name : "?" %></td>
But actually I don't believe that's the best way to handle such a situation. Also I need to know an Order created by whom even it's former user -employee- And which flavors that order contained even we don't deal with it right now. I've thought of adding a string column that contain the User name in the Orders table but then I felt it would be over bloating the database. Also I thought of soft deleting all records Or suspend users not actually delete their records from the data base. But still don't think this is a good Idea. So I need to know what is the best solution to this situation? |
