When opening Networks page in LXDUI, I always get an empty table, even though LXDUI can create new bridged network just fine. Even after that, the newly created network is not present and table stays empty.
I have been digging through the code and found out that LXCNetwork.py does actually get a list of networks from LXD API call, and populates the JSON that is then passed on to blueprint.py which should dynamically fill the network.html page with proper content - but that content is not injected into the html page and Network page stays with just an empty table.
Here's a part of the generated JSON:
res=[{'config': {'ipv4.address': '192.168.192.1/24', 'ipv4.dhcp.ranges': '192.168.192.2-192.168.192.250', 'ipv4.nat': 'true', 'ipv6.address': 'fd42:1a24:382f:2ece::1/64', 'ipv6.nat': 'true'}, 'description': '', 'name': 'lxdbr0', 'type': 'bridge', 'used_by': ['/1.0/profiles/NATed'], 'managed': True, 'status': 'Created', 'locations': ['none']}, {'config': {'ipv4.address': '10.20.30.1/24', 'ipv4.dhcp.ranges': '10.20.30.2-10.20.30.254', 'ipv4.nat': 'true', 'ipv6.address': 'fd42:411d:6e00:d25f::1/64', 'ipv6.nat': 'true'}, 'description': '', 'name': 't0', 'type': 'bridge', 'used_by': None, 'managed': True, 'status': 'Created', 'locations': ['none']},...

t0 in here is the test network that LXDUI generated fine, and lxdbr0 is the one I created directly with lxc command.

HTML template is in /usr/local/lib/python3.6/dist-packages/app/ui/templates/network.html (I installed LXDUI with pip3 on Ubuntu 18.04) and this is the table definition that does not get populated:

        <table class="table table-bordered" id="tableNetworks">
            <thead>
                <th><input type="checkbox" id="selectAllNetworks"/></th>
                <th>Name</th>
                <th>Type</th>
                <th>Config</th>
                <th>Used by</th>
                <th>Action</th>
            </thead>
            <tbody>
            {% for net in network %}
            {% if net.type == 'bridge' %}
            <tr id="{{net.name}}">
                <td></td>
                <td>{{ net.name }}</td>
                <td>{{ net.type }}</td>
                <td>
                    <ul>
                        <h5>Config:</h5>
                        {% for key, value in net.config.items() %}

                        <li>{{key}}: {{value}}</li>
                        {% endfor %}
                    </ul>
                </td>
                <td>
                 {% for used in net.used_by %}
                    <li>{{used.split('/')[-1]}}</li>
                 {% endfor %}
                </td>
                <td>
                    <button class="btn btn-default" id="{{net.name}}" name="updateBridge" onClick="$.proxy(App.network.showUpdateNetwork('{{net.name}}'));">
                        <span class="glyphicon"> </span> Update Bridge
                    </button>
                </td>
            </tr>
            {% endif %}
            {% endfor %}
            </tbody>
        </table>

So, for loop obviously does nothing and elements get no content.
Funny thing is that even if I change the network.html directly and put some chars into elements, they do not get shown.
Also funny thing is that JSON button on Networks page gives quite the correct output for all the networks that exist on the system.

Does anyone have a clue how this can be fixed? Is there some special prerequisite, permission, group ownership or anything that would make it work?

Finally, is this project still alive at all and being maintained, at least a bit? I like it because it's quite lightweight and quick to install and does most of the things for daily click-click operations, but not having any output for networks is just too big of a bug for such a simple project.

Thank you.
