title: Getting TemplateDoesNotExist error when using bootstrap3 as template pack for crispy forms
body: <p>I am using django-crispy-forms for my django project, and reading in the <a href="http://django-crispy-forms.readthedocs.org/en/latest/install.html#template-packs" rel="nofollow">documentation</a> I saw that to be able to use bootstrap3 features (like <a href="http://django-crispy-forms.readthedocs.org/en/latest/crispy_tag_forms.html#bootstrap3-horizontal-forms" rel="nofollow">horizontal forms</a>), I need to set bootstrap3 as my crispy template pack by adding this line in the settings.py of my project:</p>
  
  <pre><code>CRISPY_TEMPLATE_PACK = 'bootstrap3'
  </code></pre>
  
  <p>According to the docs, crispy's default is bootstrap v2. But after adding bootstrap3 in my settings, when I run my application in my development machine I get this error:</p>
  
  <pre><code>TemplateDoesNotExist at /dashboard/
  bootstrap3/field.html
  Request Method: POST
  Request URL:    http://localhost:8000/dashboard/
  Django Version: 1.7.3
  Exception Type: TemplateDoesNotExist
  Exception Value:    
  bootstrap3/field.html
  Exception Location: C:\Python27\VirtualEnvs\Tlaloc\lib\site-packages\django\template\loader.py in find_template, line 136
  Python Executable:  C:\Python27\VirtualEnvs\Tlaloc\Scripts\python.exe
  Python Version: 2.7.7
  </code></pre>
  
  <p>If I remove the CRISPY_TEMPLATE_PACK line from my settings (as to use the defaults) or change it to look like this:</p>
  
  <pre><code>CRISPY_TEMPLATE_PACK = 'bootstrap'
  </code></pre>
  
  <p>Then I don't get an error anymore, but then the form-horizontal class doesn't work in my form.</p>
  
  <p>This is how my form looks like in forms.py</p>
  
  <pre><code>class UserForm(forms.Form):
      user = forms.CharField(label='Account', max_length=15)
      password = forms.CharField(widget=forms.PasswordInput())
  
      # Crispy forms code
      def __init__(self, *args, **kwargs):
          super(UserForm, self).__init__(*args, **kwargs)
          self.helper = FormHelper()
          self.helper.form_class = 'form-horizontal'
          self.helper.label_class = 'col-sm-2'
          self.helper.field_class = 'col-sm-10'
          self.helper.layout = Layout(
              Fieldset(
                  '',
                  'user',
                  'password',
              ),
              Div(FormActions(
                  Submit('continue', 'Continue', css_class='btn btn-primary'),
                  Button('cancel', 'Cancel', css_class='btn btn-default',
                         data_dismiss='modal'),
                  ),
                  css_class='modal-footer'
                  )
              )
  </code></pre>
  
  <p>And this is part of my template:</p>
  
  <pre><code>{% load crispy_forms_tags %}
  
  &lt;div class="modal fade" id="adAccountModal" tabindex="-1" role="dialog" aria-labelledby="authenticationLabel" aria-hidden="true"&gt;
              &lt;div class="modal-dialog"&gt;
                  &lt;div class="modal-content"&gt;
  
                      &lt;div class="modal-header"&gt;
                          &lt;button type="button" class="close" data-dismiss="modal" aria-label="Close"&gt;&lt;span aria-hidden="true"&gt;&amp;times;&lt;/span&gt;&lt;/button&gt;
                          &lt;h4 class="modal-title" id="authenticationLabel"&gt;{{ config_values.environment_name }} Environment Authentication&lt;/h4&gt;
                      &lt;/div&gt;
  
                      &lt;div class="modal-body"&gt;
                          &lt;p&gt;Please enter the account and password that will be used to authenticate in the selected environment.&lt;/p&gt;
                          {% crispy user_form %}
                      &lt;/div&gt;
  
                      {% comment %}
                      The footer will be added through the user_form using Crispy Forms.
                      The following code will be just left here as reference. 
                      &lt;div class="modal-footer"&gt;
                          &lt;button type="button" class="btn btn-default" data-dismiss="modal"&gt;Cancel&lt;/button&gt;
                          &lt;button type="button" class="btn btn-primary"&gt;Continue&lt;/button&gt;
                      &lt;/div&gt;
                      {% endcomment %}
                  &lt;/div&gt;
              &lt;/div&gt;
          &lt;/div&gt;
  </code></pre>
  
  <p>What am I doing wrong?</p>
