title: Disable validation when calling form for the first time
body: <p>I am struggling a bit with my Django forms. When I call my form site, always validation errors appear (this field is required). I'd prefer to see this message after clicking the submit button, if a field is not filled like a javascript function would do. In addition I'm using regex for validation, which is working fine.</p>
  
  <p>I am working with CVBs. Here is some code:</p>
  
  <p>models.py</p>
  
  <pre><code> class Institute(models.Model):
      name = models.CharField(max_length=50)
      timestamp = models.DateTimeField(auto_now_add=True)  
  </code></pre>
  
  <p>views.py</p>
  
  <pre><code>class InstituteCreate(CreateView):
      model = Institute
      form_class = InstituteForm
      success_url = reverse_lazy('institute_list')
  </code></pre>
  
  <p>forms.py</p>
  
  <pre><code>class InstituteForm(forms.ModelForm):
  
      name= forms.CharField(error_messages={'required': 'Own Error Text'}, validators=[RegexValidator(regex='^[a-zA-ZäüößÄÜÖ]*$', message='forbidden string', code='string_invalid')])
  
      class Meta:
          model = Institute
          fields = ['name']
  </code></pre>
  
  <p>Hope someone has an idea on how to fix it.</p>
  
  <p>edit1:</p>
  
  <p>my template is quite simple </p>
  
  <pre><code>{% block pagetitle %}Institutes{%endblock %}
  {% block content %}
      &lt;form class="form-horizontal" name="form_group" method="post"&gt;
          {% csrf_token %}
              &lt;div&gt;
                  {{ form.as_p }}
              &lt;/div&gt;
              &lt;input class="btn btn-primary" type="submit" value="click me" /&gt;
      &lt;/form&gt;
  {% endblock %}
  </code></pre>
  
  <p>and my url config:</p>
  
  <pre><code>urlpatterns = patterns('',  
      url(r'^institute_create/$', views.InstituteCreate.as_view(), name='institute_create'),
  )
  </code></pre>
  
  <p>I'm new to Django development so i'll try to explain the problem more detailed:</p>
  
  <p>On my website, when i open the link www.exampleurl.com/institute_create my form is shown. Then i see the field where i have to enter the name for the institute. Above this field the text "this field is required" is displayed. But i don't want to see this, until i try to submit an empty form.</p>
  
  <p>When i enter some text which doesnt match and i press submit button the error text field changes its message to forbidden string as expected.</p>
