title: Form Submit button only works after reload
body: <p>I have an index page that builds a table, and I am trying to allow users to edit line's in the table.  I am trying to do this in the most basic way possible - no javascript, ajax, etc, unless Rails is supplying it.</p>
  
  <p>I have my table displaying fine in the index method, and there is a form as the last row in the table that can be used to add a new row.  The new form works fine.  Each row has an edit link that routes to the controller's edit method.  The controller sets the object to be edited, and renders index, this time with a form in the row that is to be edited.  My problem is that this form will not submit, but if I refresh the page it will submit.</p>
  
  <p>The fact that the page will submit after a refresh is very confusing.  I don't see how a refresh would do anything different then clicking the link (it should still go through the same routing, with the same variables right?) and I can't see any difference in the form html before and after the refresh.  Any have ideas on what might be happening?</p>
  
  <p>I am not sure what code to even start looking in, but here goes;</p>
  
  <p>index.html.erb</p>
  
  <pre><code>...
  &lt;tbody&gt;
    &lt;% @boms.each do |line| %&gt;
     &lt;% if line == @bom %&gt;
       &lt;%= render("form_in_table", form_objects: @bom , button_text: "Update") %&gt;
      &lt;% else %&gt;
        &lt;%= render("bom_in_table", line: line) %&gt;
      &lt;% end %&gt;
    &lt;% end %&gt;
    &lt;% if @bom.new_record? %&gt;
      &lt;%= render("form_in_table", form_objects: [@li, @bom] , button_text: "Add") %&gt;
    &lt;% end %&gt;
  &lt;/tbody&gt;
  ...
  </code></pre>
  
  <p>_form_in_table.html.erb</p>
  
  <pre><code>&lt;%= form_for(form_objects, html: {class: "form-in-table"}) do |f| %&gt;
    &lt;tr&gt;
      &lt;td&gt;&lt;%= f.text_field :quantity %&gt;&lt;/td&gt;
      &lt;td colspan="2"&gt;
        &lt;%= f.select(:part_id,
                     options_from_collection_for_select(@parts, :id, :pricebook_name),
                     prompt: "Select a Part",) %&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
      &lt;td&gt;&lt;%= f.submit(button_text, class: "btn btn-primary btn-mini") %&gt;&lt;/td&gt;
    &lt;/tr&gt;
  &lt;% end %&gt;

  <pre><code>&lt;tr&gt;

    &lt;td&gt;&lt;%= line.part_unit %&gt;&lt;/td&gt;
    &lt;td&gt;&lt;%= number_to_currency(line.extension) %&gt;&lt;/td&gt;
    &lt;td&gt;&lt;%= link_to('Edit', edit_bom_path(line)) %&gt;&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>boms_controller.rb</p>
  
  <pre><code>...
  def edit
    @bom = Bom.find(params[:id])
    @li = @bom.line_item
    @boms = @li.boms.sorted_by_part_number
    @parts = Part.sorted_by_number
    render 'index'
  end
  ...
  </code></pre>
  
  <p>In case this is useful to deciphering the code/intent, I have collections of line_items, parts, and boms; line_item has many boms, and line_item has many parts through boms.  In addition to the part/line item relationship, boms have a quantity.  Bom is short for bill of materials.  @li is the line_item that is being manipulated.  The form I having trouble with is for viewing/adding/editing the collection of boms (quantitys and parts) that belong to a line item.</p>
