title: Odoo form view create new form instead showing existing
body: <p>Every time when I click on My module menu it jump to new form instead of showing existing, I assigned access rule to my module and disable create and edit but still didn't work, what I want is when I click on my module menu it should open an existing form or I can use domain like user_id field = user.name.</p>
  
  <p>This is my code.</p>
  
  <pre><code>     &lt;record id="action_ru_students" model="ir.actions.act_window"&gt;
          &lt;field name="name"&gt;Students&lt;/field&gt;
          &lt;field name="res_model"&gt;ru.students&lt;/field&gt;
          &lt;field name="view_id" ref="students_form_view"/&gt;
          &lt;field name="view_mode"&gt;form,kanban,tree&lt;/field&gt;
      &lt;/record&gt;
  </code></pre>
  
  <p>I tried to use domain on action e.g. = <code>[("user_id","=",user.name)]</code>
  user_id is a field linked to res.user but get error user.name not found.
  also used <code>create="false" and edit="false"</code> on form still no luck.</p>
  
  <p>Any ideas how to do it?</p>
