title: Filling django select field
body: <p>So, I'm trying to implement <strong>Select widget</strong> in Django Form, to input into <strong>OneToOne</strong> area in Model.It appeared, but a problem is don't know <strong>how to fill</strong> it with initial data.</p>
  
  <p><em>models.py</em></p>
  
  <pre><code>class Check(models.Model):
      name = models.CharField(max_length = 100)
      def __unicode__(self):
           return self.name
  
  class Check_date(models.Model):
      date = models.DateTimeField()
      check = models.ForeignKey(Check)
  
      def __unicode__(self):
           return '%s' % (self.date)
  </code></pre>
  
  <p><em>forms.py</em></p>
  
  <pre><code>class Check_DateForm(forms.Form):
  date = forms.DateTimeField(label = 'Time of Check', widget  = forms.DateTimeInput)
  check_id = forms.ChoiceField(label = 'Check ID', widget = forms.Select)
  </code></pre>
  
  <p>So, there gotta be some choices, leading to Check model. I'm talking about this input. </p>
  
  <pre><code>check_id = forms.ChoiceField(label = 'Обход', widget = forms.Select)
  </code></pre>
