    <p>Maybe I'm missing something obvious (hopefully), but I'm encountering a weird problem saving records in a nested form. It's a pretty basic setup, with a minor complication in that my LineItem model is a two-word relationship (:line_items). However, I've followed Rails guidelines and it seems to be working OK.</p> <p>My fixtures are creating the proper relationships between line_items and invoices, and everything is showing up properly in my views, but I can't get any line_item records to save correctly (in my Rails console or my views).</p> <pre><code>class Invoice &lt; ActiveRecord::Base attr_accessible :line_items #and the rest of my relevant attributes has_many :line_items, :dependent =&gt; :destroy accepts_nested_attributes_for :line_items, :allow_destroy =&gt; true # Rest of my model code end class LineItem &lt; ActiveRecord::Base attr_accessible :invoice_id #and the rest of my relevant attributes belongs_to :invoice end </code></pre> <p>The <code>line_items_attributes=</code> method exists for my Invoices, but it doesn't save any line_items for new invoices. More irritating, I can edit existing line_items or assign them after the fact, but not in one fell swoop (the whole point of nested attributes?). My views can't even edit existing line_items through the invoice form. Any ideas? Happy to post more code, but didn't for sake of brevity.</p> <p>Thanks in advance...</p> <p>VIEW CODE (by request):</p> <p>(Form Partial for Invoices)</p> <pre><code>&lt;%= form_for(@invoice) do |f| %&gt; &lt;% @invoice.line_items.build unless @invoice.line_items.any? %&gt; ... &lt;% f.fields_for :line_items do |builder| %&gt; &lt;%= render 'line_item_fields', :f =&gt; builder %&gt; &lt;% end %&gt; </code></pre> <p>(Form Partial for Line Items)</p> <pre><code>... &lt;%= f.collection_select :sku_id, @skus, :id, :name, :prompt =&gt; true %&gt; &lt;%= f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") %&gt; </code></pre> <p>(javascript)</p> <pre><code>function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } </code></pre>

    1. COPlease show your view-code. Are you using `fields_for`?

    2. COWow, I haven't been able to spot anything wrong with the code you've posted. I'm leaning toward thinking this is an object issue, nothing to do with the controller or view layers. I don't have time to dig into this now, hopefully someone else can jump in. Have you attempted to set attributes in console? If it fails, you have a model issue. If it succeeds, the issue is in the controller/view. Good luck, and I'll check back later.

    3. CO@Jaime: The console is acting super weird. I can create an invoice and set attributes for a new 'line_item' or several. When I actually save, validations pass, but no line_items are created (so I'm left with an empty invoice and no notification that anything went wrong). I cannot manipulate or destroy anything in my views. I'm going crazy...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
