    <p>I'm getting an <code>ActiveSupport::HashWithIndifferentAccess</code> error when I try to update an embedded form.</p> <p>Here's the simplest example:</p> <p>Form:</p> <pre><code>&lt;h1&gt;PlayersToTeams#edit&lt;/h1&gt; &lt;%= form_for @players_to_teams do |field| %&gt; &lt;%= field.fields_for @players_to_teams.player do |f| %&gt; &lt;%= f.label :IsActive %&gt; &lt;%= f.text_field :IsActive %&gt; &lt;% end %&gt; &lt;%= field.label :BT %&gt; &lt;%= field.text_field :BT %&gt; &lt;br/&gt; &lt;%= field.submit "Save", class: 'btn btn-primary' %&gt; &lt;% end %&gt; </code></pre> <p>Models:</p> <pre><code>class PlayersToTeam &lt; ActiveRecord::Base belongs_to :player belongs_to :team accepts_nested_attributes_for :player end class Player &lt; ActiveRecord::Base has_many :players_to_teams has_many :teams, through: :players_to_teams end </code></pre> <p>Controller:</p> <pre><code>class PlayersToTeamsController &lt; ApplicationController def edit @players_to_teams=PlayersToTeam.find(params[:id]) end def update @players_to_teams=PlayersToTeam.find(params[:id]) respond_to do |format| if @players_to_teams.update_attributes(params[:players_to_team]) format.html { redirect_to @players_to_teams, notice: 'Player_to_Team was successfully updated.' } format.json { head :no_content } else format.html { render action: "edit" } format.json { render json: @players_to_teams.errors, status: :unprocessable_entity } end end end end </code></pre> <p>This is the <code>params[:players_to_team]</code> object upon form submission:</p> <p><img src="https://i.stack.imgur.com/lx5QK.png" alt=":players_to_team "> </p> <p>What does an <code>ActiveSupport::HashWithIndifferentAccess</code> error mean? What do I need to do to have this form update the <code>players_to_team</code> entry?</p> <p><strong>Edit</strong></p> <p><code>BT</code> is a column in <code>players_to_teams</code>. If I remove teh <code>field_for</code> block, I can successfully save the <code>BT</code> field/the <code>players_to_teams</code> row.</p> <p>Thanks</p>

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.
