title: How can I exclude few fields from validation in forms
body: <p>I have 10 fields in a Django form like this</p>
  
  <pre><code>class SearchForm(forms.Form):
      student_number                 = forms.CharField(required=False)
      final_date                      = forms.DateField(required=False)
      location_area                   = forms.FloatField(required=False)
  </code></pre>
  
  <p>In my <code>form.is_valid()</code> I want to exclude few fields from validation like</p>
  
  <p><code>[location_area, final_date]</code> and rest all perform validation or only want to validate <code>charfields</code> not <code>select fields</code>.</p>
  
  <p>How can I do that?</p>
