I am stuck a the point where you bind the URL to the Button and the field in the settings for the hello world plug in. *Note I have removed all instances if “http” as it said I could only post 5 links as a new user.
It loads ok and displays the s://de.wikipedia.org/wiki/Hallo-Welt-Programm in the start up in terminal but when I click the Hello world button it does nothing. Nor does the URL load into the box in the settings. I have spent ages on this and I can't seem to figure out why. I don't have any space or tab errors when it loads so I don't think it's a formatting issue.
def on_after_startup(self):
self._logger.info("Hello World! (more: %s)" % self._settings.get(["url"]))
is working. So the URL is being read from the config.yaml.
My hello world_settings.jinja2 has the right code
<form class="form-horizontal">
<div class="control-group">
<label class="control-label">{{ _('URL') }}</label>
<div class="controls">
<input type="text" class="input-block-level" data-bind="value: settings.plugins.helloworld.url">
</div>
</div>
</form>
my helloworld_navbar.jinja2 has the following code.
a href="javascript:void()" data-bind="attr: {href: settings.settings.plugins.helloworld.url}">Hello World!</a>
I am running it on macOS sequioa and in the development environment as set out in the tutorial. Any help would be appreciated. I have tried it on Firefox and Safari and the result is the same.
Here's the log:
