| Set default value of date_field only if current value is empty Posted: 05 Jul 2016 07:47 AM PDT I'm using the same form in a partial to both create a new object and modify it. I have the following field: <%= f.date_field :dob, class: 'form-control' %>
I know that I can set its default by adding value: Time.now.strftime('%Y-%m-%d'), but I want to do this if and only if the current value is empty. How do I do that? |

| How to make hash/array of params out of several selects? Posted: 05 Jul 2016 07:23 AM PDT I have two select dropdowns and when a user selects an option from each of them It has to group them in the following manner: job => { "types" => [1,2,3] }
or at least like this: job => { "types" => { "first" => "1", "second" => "2" } }
Is this possible to do in Rails? For example, this example only sends the last select value: <%= simple_form_for @job, url: jobs_path do |f| %> <% 2.times do %> <%= f.input :types, as: :select, collection: @types %> <% end %> <% end %>

| params hash problems with a hidden form post request Posted: 05 Jul 2016 07:36 AM PDT I have this hidden form: <form action="/event_signup" method="post"> <input type="hidden" name="user_id" value="<%= session[:current_user]%>"> <input type="hidden" name="event_id" value="<%= event.id%>"> <input type="hidden" name="authenticity_token" value="<%= form_authenticity_token%>"> <input type="submit" value="Sign up"> </form>
this is my event_attendances controller: class EventAttendancesController < ApplicationController def create @event_attendance = EventAttendance.new(attendance_params) if @event_attendance.save flash[:success] = "Signed up for event successfully" else flash[:danger] = "An error occured whilst trying to sign you up for an event" end redirect_to root_url end private def attendance_params params.require(:event_attendance).permit(:event_id, :user_id) end end
my route is set up as so: post 'event_signup' => 'event_attendances#create'
however I get an error when I click the submit form button: ActionController::ParameterMissing in EventAttendancesController#create
and when I try and see my params hash in the console I receive a name error: NameError: undefined local variable or method `params'
But I can see on the error page that my params hash is looking as it should: Request Parameters: {"user_id"=>"1", "event_id"=>"1", "authenticity_token"=>"FskE5u1cxfN4JklMfM/JqKtg3t45tyP1z6ivUVmyLx+zlY7aShQDn+eF6aoOXp/StH6svsawXVtSCZcfe4UcsQ=="}
And here is my event attendance model: class EventAttendance < ActiveRecord::Base belongs_to :user belongs_to :event end

| Curl in vagrant to reference itself Posted: 05 Jul 2016 07:35 AM PDT I currently have a project running on a Ubuntu virtual machine on my computer. I am using Vagrant and Virtual Box to set up this environment and have the Puma server up and running with the command: bundle exec puma
Which provided the following output: Puma starting in single mode... * Version 3.4.0 (ruby 2.3.0-p0), codename: Owl Bowl Brawl * Min threads: 0, max threads: 16 * Environment: development D [2016-07-04 11:26:23 $2728] DEBUG | : Register a receiver for (reschedule) queue D [2016-07-04 11:26:25 $2728] DEBUG | : Register a receiver for (trial) queue D [2016-07-04 11:26:25 $2728] DEBUG | : Register a receiver for (free) queue D [2016-07-04 11:26:25 $2728] DEBUG | : Register a receiver for (renew) queue D [2016-07-04 11:26:25 $2728] DEBUG | : Register a receiver for (renew_charge_response) queue D [2016-07-04 11:26:25 $2728] DEBUG | : Register a receiver for (merchant_notification) queue D [2016-07-04 11:26:25 $2728] DEBUG | : Register a receiver for (renew_charge) queue D [2016-07-04 11:26:25 $2728] DEBUG | : Register a receiver for (partial_renew_charge) queue * Listening on tcp://0.0.0.0:9292 Use Ctrl-C to stop
I wish to now be able to make calls to this via curl commands. At present I am able to curl to the live API which leads me to believe that my curl command is correct however when i do the same to my test environment, contained within my virtual machine I get an error referring to "Basic Auth required". From this I am assuming that I am hitting the API correctly as the error returned is one contained within the API code. My problem is Basic Authentication as I have created a user and password in my environment. I have base64 encoded this and fed the resulting string into my curl statement like below: curl -L http://127.0.0.1:9292/v2.2/ -H "Authorization: Basic cGF5bWVudHM6cGF5bWVudHM="
For some reason it is not being accepted. Can anyway provide me with some indication as to how I could go about diagnosing the problem. Thanks in advance. |
