How can I render out a public page from admin?

daviesgeek - 3 months ago

I want to render a public page from the admin end of things, but I'm running into all sorts of trouble doing so. I basically copied the functionality from LoadCurrentTheme.php like so:

In my controller's constructor:

$this->themes     = $themes;
$this->config     = $config;
$this->asset      = $asset;
$this->manager    = $manager;
$this->view       = $view;
$this->image      = $image;
$this->translator = $translator;

$standard = $this->themes->get($this->config->get('streams::themes.standard'));
$admin    = $this->themes->get($this->config->get('streams::themes.admin'));

$admin->setCurrent(false);
$admin->setActive(false);
$standard->setCurrent(true);
$standard->setActive(true);

if ($theme = $this->themes->current()) {
  $this->view->addNamespace('theme', $theme->getPath('resources/views'));
  $this->translator->addNamespace('theme', $theme->getPath('resources/lang'));

  $this->asset->addPath('theme', $theme->getPath('resources'));
  $this->image->addPath('theme', $theme->getPath('resources'));
}
$page = $pages->find(1);

$page->setCurrent(true);
$page->setActive(true);

$type    = $page->getType();
$handler = $type->getHandler();

$template->set('page', $page);

$handler->make($page);

$htmlString = $page->getResponse()->getContent();

// Do stuff here

return $page->getResponse();

The problem is that the theme isn't set correctly and the assets are not loading correctly. I get this error:

"Asset [<pyro-path>/core/pyrocms/starter-theme/resources/less/fonts/fonts.less] does not exist!" in "theme::partials/metadata"

Somehow it's trying to load the wrong partials/metadata, which causes the fonts.less file to attempt to be loaded, and it fails. It seems to me like I need to unset something with Assetic, but I'm not sure. Any suggestions?

I think the only way to really do this is either use frames and load the page outside of the "admin" URL. The segment_1 == admin logic is what switching the themes out.

Your second alternative is to not rely on 'theme' if possible. Reference the theme directly with it's full dot namespace.

Hmm okay. Frames won't exactly work, since I'm attempting to write the page to disk and cache it on S3.

The second alternative might be better, but I think I'm going to take an alternative approach to this solution.

  • Frames won't work without a lot of crazy hacks to fetch the page.

Have you succeeded? I'd be interested to hear the scenario for this requirement!

The closest I got to needing something unconventional to how Pyro does thing is to have Modules with built-in themes, I needed that for a theme-able Survey Module,

Finally, if I were to have that need, I would have tried to override the route in question and use a standard controller,
