title: How to change Submit button text from a view in crispy-forms?
body: <p>In my forms.py I have the following:</p>
  
  <pre><code>self.helper.layout = Layout(
      Fieldset(
          None,
          'name'
      ),
      FormActions(
          Submit('submit', 'Add Thing', css_class='btn-primary')
      )
  )
  </code></pre>
  
  <p>But I am using the same view to add and edit the item. So I want to change the button text (Add Thing above) based on some condition in my views.py. How can I do that?</p>
