    <p>I'm using <em>MopaBootstrapBundle</em> in <em>Symfony 2.1.3</em> with <em>Twig</em> templates. This bundle has <em>base.html.twig</em> template which contains scripts block:</p> <pre><code>{% block foot_script %} {# To only use a subset or add more js overwrite and copy paste this block To speed up page loads save a copy of jQuery in your project and override this block to include the correct path Otherwise the regeneration is done on every load in dev more with use_controller: true #} {% javascripts 'http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-transition.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-modal.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-dropdown.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-scrollspy.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-tab.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-tooltip.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-popover.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-alert.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-button.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-collapse.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-carousel.js' '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-typeahead.js' '@MopaBootstrapBundle/Resources/public/js/mopabootstrap-collection.js' '@MopaBootstrapBundle/Resources/public/js/mopabootstrap-subnav.js' %} &lt;script type="text/javascript" src="{{ asset_url }}"&gt;&lt;/script&gt; {% endjavascripts %} {% endblock foot_script %} </code></pre> <p>I'm extending it in my template using:</p> <pre><code>{% extends 'MopaBootstrapBundle::base.html.twig' %} {% block foot_script %}{% endblock foot_script %} </code></pre> <p>But it still tries to load Bundle's <em>base.html.twig</em> template and I get:</p> <blockquote> <p>An exception has been thrown during the compilation of a template ("Unable to find file "@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-transition.js".") in "MopaBootstrapBundle::base.html.twig".</p> </blockquote> <hr> <p>What I've found out is, that if you extend it like this:</p> <pre><code>{% extends 'MopaBootstrapBundle::base.html.twig' %} {% block foot_script %} {% javascripts '@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-typeahead.js' '@MopaBootstrapBundle/Resources/public/js/mopabootstrap-collection.js' '@MopaBootstrapBundle/Resources/public/js/mopabootstrap-subnav.js' %} &lt;script type="text/javascript" src="{{ asset_url }}"&gt;&lt;/script&gt; {% endjavascripts %} {% endblock foot_script %} </code></pre> <p>Note the <em>typeahead.js</em></p> <p>I get:</p> <blockquote> <p>An exception has been thrown during the compilation of a template ("Unable to find file "@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-typeahead.js".") in "MopaBootstrapBundle::base.html.twig".</p> </blockquote> <p>If I remove just one line:</p> <pre><code>{% extends 'MopaBootstrapBundle::base.html.twig' %} {% block foot_script %} {% javascripts '@MopaBootstrapBundle/Resources/public/js/mopabootstrap-collection.js' '@MopaBootstrapBundle/Resources/public/js/mopabootstrap-subnav.js' %} &lt;script type="text/javascript" src="{{ asset_url }}"&gt;&lt;/script&gt; {% endjavascripts %} {% endblock foot_script %} </code></pre> <p>I get:</p> <blockquote> <p>An exception has been thrown during the compilation of a template ("Unable to find file "@MopaBootstrapBundle/Resources/bootstrap/js/bootstrap-transition.js".") in "MopaBootstrapBundle::base.html.twig".</p> </blockquote> <p>It still tries to load all the scripst from base template.</p> <p>Any suggestions how to override *foot_script* block to make it empty and not to load these JS files?</p>

    1. COI think the problem is that first the `{% javascripts %}` tag is parsed and after that the `{% block %}` tags. I don't know how you can fix this. [This issue by fabpot](https://github.com/symfony/symfony-docs/issues/752) can maybe help you?

    2. COI even don't know if that's a solution (I don't think so), but if files are found in that bootstrap directory, then it works as expected.

    3. COAs a quick fix, maybe load some dummy empty js file from your bundle like: {% extends 'MopaBootstrapBundle::base.html.twig' %} {% block foot_script %} {% javascripts '@MyBundle/Resources/public/js/dummy-file.js'%} {% endblock foot_script %}

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
