Rails 4.1: NameError in Jobs#new

Question

Want to show different job categories for my jobs board , using the simple form gem I have added the following to my jobs form.

_form.html.erb

<%= simple_form_for(@job, html: { class: 'form-horizontal' }) do |f| %>

<%= f.collection_select :category_id, Category.all, :id, :name, {prompt: "Choose a category" }, input_html: { class: "dropdown-toggle" } %>


    <%= f.input :title, label: "Job Title", input_html: { class: "form-control" } %>
    <%= f.input :description, label: "Job Description", input_html: { class: "form-control" } %>
    <%= f.input :company, label: "Your Company", input_html: {class: "form-control" } %>
    <%= f.input :url, label: "Link to Job", input_html: { class: "form-control" } %>
    <br/>
    <div class="form-group">
    <%= f.submit class: "btn btn-primary" %>
  </div>
<% end %>

but when i go to jobs.new.html it generates the following error

NameError in Jobs#new Showing /Users/neilpatel/Desktop/Rails/jobs_board/app/views/jobs/_form.html.erb where line #3 raised: uninitialized constant ActionView::CompiledTemplates::Category

<%= simple_form_for(@job, html: { class: 'form-horizontal' }) do |f| %>

  **<%= f.collection_select :category_id, Category.all, :id, :name, {prompt: "Choose a category" }, input_html: { class: "dropdown-toggle" } %>** -<error


    <%= f.input :title, label: "Job Title", input_html: { class: "form-control" } %>

Error specifies you don't have Category Model in your application. That's why rails considering Category as constant and throwing this error uninitialized constant. Try add Category Model in you app/models directory.

<%= f.collection_select :category_id, Category.all, :id, :name, {prompt: "Choose a category" }, input_html: { class: "dropdown-toggle" } %>

Category.all Should be Modelname.all
