title: Django - How to change value of forms.ModelChoiceField
body: <p>I want to output the value from my Models Name column using <code>forms.ModelChoiceField</code>. I have read a lot of documentation on the subject but its proving difficult to achieve the desired results!</p>
  
  <p>Here is my code.</p>
  
  <p>I have this form:</p>
  
  <p>forms.py</p>
  
  <pre><code>from django import forms
  from asset_db.models import Profiles
  
  
  class SubmitJob(forms.Form):
  
      material_id = forms.CharField(max_length=8)
      workflow = forms.ModelChoiceField(queryset=Profiles.objects.distinct('name'))
      start_datepicker = forms.CharField(max_length=12)
      end_datepicker = forms.CharField(max_length=12)
  </code></pre>
  
  <p>This model:</p>
  
  <pre><code>class Profiles(models.Model):
  
      id = models.DecimalField(6).auto_creation_counter
      name = models.CharField(max_length=256, default='null')
      target_path = models.CharField(max_length=256, default='null')
      target_profile = models.TextField(max_length=1024, default='null')
      package_type = models.CharField(max_length=256, default='null')
      video_naming_convention = models.CharField(max_length=256, default='null')
      image_naming_convention = models.CharField(max_length=256, default='null')
      package_naming_convention = models.CharField(max_length=256, default='null')
  
      def __str__(self):
          return self.name
  </code></pre>
  
  <p>Here is the HTML output:</p>
  
  <pre><code>&lt;p&gt;&lt;label for="id_workflow"&gt;Workflow:&lt;/label&gt; &lt;select id="id_workflow" name="workflow" required&gt;
  &lt;option value="" selected="selected"&gt;---------&lt;/option&gt;
  &lt;option value="2"&gt;Amazon&lt;/option&gt;
  &lt;option value="1"&gt;Test&lt;/option&gt;
  &lt;/select&gt;&lt;/p&gt;
  </code></pre>
  
  <p>I want to know how to change the value of "value" to the column "name" in my model, for example:</p>
  
  <pre><code>&lt;p&gt;&lt;label for="id_workflow"&gt;Workflow:&lt;/label&gt; &lt;select id="id_workflow" name="workflow" required&gt;
  &lt;option value="" selected="selected"&gt;---------&lt;/option&gt;
  &lt;option value="Amazon"&gt;Amazon&lt;/option&gt;
  &lt;option value="Test"&gt;Test&lt;/option&gt;
  &lt;/select&gt;&lt;/p&gt;
  </code></pre>
  
  <p>Thanks in advance.</p>
