Re: [Rails] associations - one to many

Ruby on Rails Friday, September 30, 2016

Ok, here is my edit products page...

<% if user_signed_in? %>  <!-- fix this change to admin user -->

<h1>Editing Product</h1>

<%= render 'form' %>

<%= link_to 'Show', @product %> |
<%= link_to 'Back', products_path %>

<% else %>


    <div class="alert alert-warning" role="alert">You must be signed in as administrator to edit the products.</div>
  
<% end %> 


here is my _form

<%= simple_form_for(@product) do |f| %>
  <%= f.error_notification %>


 <!-- fix this -->
 <div class = "field">
    
    <%= f.label :category %><br/>
    
    <%= f.collection_select :category, Category.all, :id, :name %>
  </div>
  <!-- fix this, it should save the category to the model -->
  
  <div class="form-inputs">
    
    <%= f.input :title %>
    <%= f.input :template %>
    <%= f.input :price %>
    <%= f.input :msrp %>
    <%= f.input :enddate %>
    <%= f.input :draft %>
  
 
  </div>

  <div class="form-actions">
    <%= f.button :submit %>
  </div>
<% end %>

You need to show the code for your edit

I've got two tables in my Postgres database: categories and products.

I have a one to many relationship defined, one category can have many products.


I then created a reference and migrated the tables.

AddCategoryRefToProducts category:references


I have this in my models.

#product.rb  belongs_to :category    #category.rb  has_many :products


I've fixed the _form to include the category id.   But when I edit or update the form, the category id is not written to the product table.


I think I'm missing a step somewhere, not sure where.


Any suggestions?


Thanks,

Joe
