Ruby Index and Show views are showing no data - ruby-on-rails

I'm new to Ruby, and I'm developing my own app in Nitrous.
When I complete a form on my new.html.erb, and hit save, the show view loads. The page renders with HTML headers as expected, but no data fields from my model. I have also tried the index view, but there is no data being saved, I think.
I have generated a model called income, and run rake db:migrate successfully, wiht the right tables set up. I'm stumped as to what the problem is.
Any ideas gratefully received.
This is my controller: incomes_controller.rb
class IncomesController < ApplicationController
def index
#incomes = Income.all
end
def new
#income = Income.new
end
def create
#income = Income.new(income_params)
if #income.save
redirect_to(:action => 'show', :id => #income.id)
end
end
def show
#income = Income.find(params[:id])
end
private
def income_params
params.require(:income).permit(:first_name, :last_name, :date_of_birth, :income1, :income2, :income3, :income4, :income5, :income6, :income7, :income8, :income9, :income10)
end
end
My form in new.html.erb, is:
<%= simple_form_for #income do |f| %>
<%= f.input :first_name, label: 'First Name' %>
<%= f.input :last_name, label: 'Last Name' %>
<%= f.input :date_of_birth, label: 'Date of Birth', hint: 'dd/mm/yyyy' %>
<p>Income: Salary or Wages</p>
<%= f.input :income1, label: 'Take home salary or Wage' %>
<%= f.input :income2, label: 'Partner\'s salary or wage' %>
<%= f.input :income3, label: 'Other income from salary or wages' %>
<p>Other Income</p>
<%= f.input :income4, label: 'Maintanence or child support' %>
<%= f.input :income5, label: 'Boarders or lodgers' %>
<%= f.input :income6, label: 'Non-dependent contributions' %>
<%= f.input :income7, label: 'Student loands or grants' %>
<%= f.input :income7, label: 'Other' %>
<p>Benefits </p>
<%= f.input :income8, label: 'Sample input' %>
<%= f.input :income9, label: 'Sample input' %>
<%= f.input :income10, label: 'More sample inputs' %>
<%= f.button :submit, "Save and Proceed" %>
<h3>You will have a chance to review your form before you submit it. Once you click Save, you can come back and complete the rest of the form at a later date</h3>
<% end %>
And my show.html.erb file is:
<p>
<strong>First name:</strong>
<%= #income.first_name %>
</p>
<p>
<strong>Last name:</strong>
<%= #income.last_name %>
</p>
<p>
<strong>Date of Birth:</strong>
<%= #income.date_of_birth %>
</p>
<p>
<strong>Take home salary or Wage:</strong>
<%= #income.income1 %>
</p>
My model income.rb is:
class Income < ActiveRecord::Base
attr_accessor :first_name, :last_name, :date_of_birth, :income1, :income2, :income3, :income4, :income5, :income6, :income7, :income8, :income9, :income10
end

Thanks to #RailsOuter and #jyrkim for your help. I found that the problem was indeed with my model file, and migration file.
I needed to remove the line attr_accessor from my model. I have since discovered that I must have modified my migration file to add columns, instead of generating a new migration. Now I have generated the new migration with the data columns, my data is showing!
Thanks again, very appreciative of your input to help out a newbie!

Upload doesn't work using Carrierwave in Rails 5

So I was working on my app and trying to put on an uploader feature.
First I generated a course uploader and allowed jpeg, jpg, png and gif.
Next I've added the ff code mount on my course model:
mount_uploader :thumb_image, CoursesUploader
mount_uploader :main_image, CoursesUploader
Next, I place the file upload form code on my new.html.erb file:
<div class="field">
<%= f.file_field :main_image %>
</div>
<div class="field">
<%= f.file_field :thumb_image %>
</div>
And when I tried to submit my form with my images uploaded it did not even show the index page instead I refresh the page and then see if it got uploaded and the form was submitted successfully but it did not.
I also look at the strong params on my controller and these two items are there:
# Never trust parameters from the scary internet, only allow the white list through.
def course_params
params.require(:course).permit(:title, :price, :body, :main_image, :thumb_image)
end
Any idea what am I missing here?
Here's something I got from my terminal after submission:

validates_presence_of :title, :price, :body, :main_image, :thumb_image
=> So just fillup body field in form or remove validates_presence_of :body
I can see the Image is ActionDispatch already but are you sure you created your table column like this -Regardless of creating table or adding_column-
I'm focusing on
:string, array: true, default: []
Migration should look like:
add_column :courses, :main_image, :string, array: true, default: []
As creating the column as String won't let carrierwave add it's object as an array inside it, so it should be an array
Also you can set thumb and main images in one uploader if you are going to change the size only, otherwise you're fine to use :thumb_image and :main_image but make sure the migration is correct
If you can't change it, just drop and re-create it

params being passed from form_for but not inserted/commited to database

I have a form submitting a value to my create controller. In the server log, I see the parameter (:style) being passed, but not inserted into database. Does someone know how that could happen?

Thank you for the assistance!
This happens because your form submits the styleattribute value like style instead of cupboard[style]. Looks like you're mixing form_for methods with form_tag ones and you need to replace radio_button_tag with radio_button. Also note that there are 2 forms of notations: either the function invocation radio_button(:model_name, :col_name, 'value') or the method invocation on the form object itself f.radio_button(:col_name, 'value'). Another issue with your form is that you're using label for each radio while it's designed to be used once for every group of radio buttons. Hence, the form should look like this:
<%= form_for #cupboard, html: { class: 'listform' } do |f| %>
<%= f.label :style, class: 'welcomelistitem' %>
<%= f.radio_button :style, 'ATHLEISURE' %>
<%= f.radio_button :style, 'CASUAL' %>
<%= f.radio_button :style, 'PROFESSIONAL' %>
<%= f.radio_button :style, 'WEEKEND' %>
<%= f.radio_button :style, 'FESTIVAL' %>
<%= f.radio_button :style, 'DATENIGHT' %>
<%= f.submit 'Make a new closet' %>
<% end %>
You'll then have to rewrite the cupboard_params method like this:
def cupboard_params
params.require(:cupboard).permit(:style)
end
Didn't have time to check if this works, but seems like it should.
The parameter "style" is not being passed inside of params[:cupboard]. It is directly in params.
I don't see the other params (besides style) in your form so I'm not sure what is going on there but try this
def cupboard_params
params.permit(:style)
end
Or change your radio buttons in the view to this
radio_button_tag('cupboard[style]', "ATHLEISURE")

New ticket is being created when loading a new form

This is my first question on here, so I am hoping I have not asked it incorrectly.
I have a generic new action on my tickets controller. Whenever I load tickets/new, it is creating a new item in the DB and committing it.
Here is the output from the server when the page is loading.

Help!!
--Tim
INSERT INTO `tickets` (`category`, `created_at`, `updated_at`) VALUES (3, '2016-02-11 05:14:47', '2016-02-11 05:14:47')
This is getting category (3) from somewhere, suggesting that there is some functionality somewhere which is saving the #ticket.
The simplest explanation I can see is that you have a before_action somewhere. It would benefit to show your entire TicketsController:
#app/controllers/tickets_controller.rb
class TicketsController < ApplicationController
before_action :set_user #-> something like this??
end
Since you're new, you can make your routes much more succinct (multiple resources):
#config/routes.rb
methods = %i(step_1 new_ticket billing_new_1 internet_step_1 internet_step_2 internet_modem_reset internet_create_1 internet_create_2 tv_step_1 tv_step_2 tv_step_3 tv_create_1 tv_create_2 tv_create_3 closed sidenav)
resources :tickets do
resources :notes, :appointments
collection do
methods.each {|method| get method }
end
put :close, on: :member
end
I ended up starting the whole ticket class over.
I think the error was in my html.
My guess is that the if statement with the bang was causing the ticket to save, because of an enum with that name on the model.
Here is what I think was the bad html.
<% if #ticket.category == :tv %>
Ok. Your tv is down, but your internet is still working.

Rails 4 nested attribute hash keys showing as unpermitted

I have a Category model and a Standard model. A category has many standards through a "join table" model CategoryStandard. In my view, I have a form where I can edit the category description, and then add or remove standards from that category. So, my nested attributes are for :category_standards, because I'm not editing the standard itself, just adding or removing relationships, if that makes sense.
Here's the important part of the view:
<%= form_for(#category) do |f| %>
...
<div class="field">
<%= f.label :description %>
<%= f.text_field :description %>
</div>
<%= label_tag nil, "Standards in this Category" %>
<div id="standard-list">
<%= f.fields_for :category_standards do |ff| %>
<div class="field">
<%= ff.object.standard.number_with_exceptions %>
<%= ff.hidden_field :standard_id %>
<%= ff.hidden_field :_destroy %>
<%= link_to "<span class='glyphicon glyphicon-remove'></span>".html_safe, "", class: "del-std-btn", title: "Remove standard from category" %>
</div>
<% end %>
<div class="hidden" id="std-add-new-template">
<div class="field">
<%= f.fields_for :category_standards, CategoryStandard.new, child_index: "new_id" do |ff| %>
<%= ff.collection_select :standard_id, #standards - #category.standards, :id, :number_with_exceptions, prompt: "Select a standard to add" %>
<% end %>
</div>
</div>
</div>
...
<% end %>
There's some jQuery under the hood to manipulate the "rows", but that works fine and I don't think it's part of my problem, so I'll omit it.
In my Category model, I have:
class Category < ActiveRecord::Base
has_many :category_standards, dependent: :destroy
has_many :standards, through: :category_standards
validates :description, presence: true,
uniqueness: true
accepts_nested_attributes_for :category_standards, allow_destroy: true, reject_if: proc { |attributes| attributes['standard_id'].blank?}
end
And in my Categories controller, I have:
def category_params
params.require(:category).permit(:description, category_standards_attributes: [:id, :standard_id, :_destroy])
end
But when I try to add a standard to a category, I get these lines in my server log (reformatted in the hopes of making it more readable):
Parameters: {"utf8"=>"✓",
"authenticity_token"=>"***********",
"category"=>{
"description"=>"Drinking Water System Components",
"category_standards_attributes"=>{
"0"=>{
"standard_id"=>"2",
"_destroy"=>"false",
"id"=>"1"
},
"new_id"=>{
"standard_id"=>""
},
"1424899001814"=>{
"standard_id"=>"1"
}
}
},
"commit"=>"Save Changes",
"id"=>"2"
}
User Load (5.0ms) SELECT "users".* FROM "users" WHERE "users"."id" = 1 ORDER BY "users"."id" ASC LIMIT 1
Category Load (4.0ms) SELECT "categories".* FROM "categories" WHERE "categories"."id" = $1 LIMIT 1 [["id", "2"]]
Unpermitted parameters: 0, new_id, 1424899001814
(4.0ms) BEGIN
Category Exists (6.0ms) SELECT 1 AS one FROM "categories" WHERE ("categories"."description" = 'Drinking Water System Components' AND "categories"."id" != 2) LIMIT 1
SQL (6.0ms) UPDATE "categories" SET "description" = $1, "updated_at" = $2 WHERE "categories"."id" = 2 [["description", "Drinking Water System Components"], ["updated_at", Wed, 25 Feb 2015 21:16:44 UTC +00:00]]
It updates the description field just fine, but what's up with the Unpermitted parameters? My attributes hash comes out just like the example in the Rails Guide on nested forms, and it even says "The keys of the :addresses_attributes hash are unimportant, they need merely be different for each address." And yet it's the keys that are getting denied for me.
Where have I gone wrong? Thanks!
Figured it out, after a lot of reading. The missing piece was here.
Hashes with integer keys are treated differently and you can declare the attributes as if they were direct children. You get these kinds of parameters when you use accepts_nested_attributes_for in combination with a has_many association:
# To whitelist the following data:
# {"book" => {"title" => "Some Book",
# "chapters_attributes" => { "1" => {"title" => "First Chapter"},
# "2" => {"title" => "Second Chapter"}}}}
params.require(:book).permit(:title, chapters_attributes: [:title])
The important part of that was "Hashes with integer keys". My hash keys were passing as "0", "new_id", "1240934304343". It isn't important that I use "new_id", because that's just a placeholder value that gets changed in my jQuery when new rows are added. Only the template row retains that value, which is fine, because it gets filtered out by my reject_if clause.
But the fact that "new_id" isn't an integer apparently was the thing that was mucking it all up. So I changed it to "-1", which Rails accepts (even though it is still filtered out by reject_if, as it should be).
<div class="hidden" id="std-add-new-template">
<div class="field">
<%= f.fields_for :category_standards, CategoryStandard.new, child_index: "-1" do |ff| %>
<%= ff.collection_select :standard_id, #standards - #category.standards, :id, :number_with_exceptions, prompt: "Select a standard to add" %>
<% end %>
</div>
</div>
Your attribute keys don't seem to match what you are expecting in your strong parameters, "new_id" and "1424899001814" certainly will not be permitted.
"new_id"=>{
"standard_id"=>""
},
"1424899001814"=>{
"standard_id"=>"1"
}
I suspect the way you are constructing your form is invalid. Try breaking it down to the simplest working form.. like:
<div id="standard-list">
<%= link_to "<span class='glyphicon glyphicon-remove'></span>".html_safe, "", class: "del-std-btn", title: "Remove standard from category" %>
<div class="hidden" id="std-add-new-template">
<div class="field">
<%= f.fields_for :category_standards do |ff| %>
<%= ff.object.standard.number_with_exceptions %>
<%= ff.hidden_field :standard_id %>
<%= ff.hidden_field :_destroy %>
<%= ff.collection_select :standard_id, #standards - #category.standards, :id, :number_with_exceptions, prompt: "Select a standard to add" %>
<% end %>
</div>
</div>
</div>
The intention is to have only one nested form, and by stripping it down create only one nested hash.
"category_standards_attributes"=>{
"0"=>{
"standard_id"=>"2",
"_destroy"=>"false",
"id"=>"1"
}
}
What happens with this?

Update method not updating table using rails 4

I am having difficulty translating the Headfirst into Rails book which is based on Rails 2 into Rails 4 which is set up on my machine.
The exercise is trying to retrieve a record from a database and then, once edited, update the table.
I have tried many different ways and my current configuration is as follows - this will present the record for editing but will not actually update the record! (Infuriating!)
NB - I am not using 'strong_parameters' nor 'protected_attributes' - I did try this but was getting stack to deep and other errors.
My ad model is also empty - I have removed the att_accessible entries that I tried with the protected attributes gem.
Here is my - ad controller entry:
def update
#ad = Ad.find(params[:id])
#ad.update_attributes(update_params[:id])
redirect_to "/ads/#{#ad.id}"
end
private
def update_params
params.permit(:name, :description, :price, :seller_id, :email, :ad, :img_url)
end
end
EDIT VIEW:
<h1>Editing <%= #ad.name %></h1>
<%= form_for(#ad,:url=>{:action=>'update'}) do |f| %>
<p><b>Name</b><br /><%= f.text_field :name %></p>
<p><b>Description</b><br /><%= f.text_area :description %></p>
<p><b>Price</b><br /><%= f.text_field :price %></p>
<p><b>Seller</b><br /><%= f.text_field :seller_id %></p>
<p><b>Email</b><br /><%= f.text_field :email %></p>
<p><b>Img Url</b><br /><%= f.text_field :img_url %></p>
<p><%= f.submit "update" %></p>
<% end %>
