Home Page Blog

psaunders - 2 months ago

I'm just working out how to perform a relatively common request: How do I make make the home page show either (A) the blog module or (B) a couple of posts? Back with the details in a bit.

Update 1 The docs and various stock theme parts show examples that have something along the lines of:

{% posts = entries('posts').paginate() %}
{% for post in posts %}
    <p>
        {{ post.title }}
    </p>
{% endfor %}
{{ posts.links|raw }}

There is also an example that has posts in this format, which looks like some sort of eager loading but I can't find the entries() function in the code so it must be parsed into something with a different name.

{% for category in entries('posts', 'categories').get() %}
   <li>
      {{ category.slug }}
</li>
{% endfor %}

You can't just paste this markdown into the WYSIWYG editor or the page will 500, so you probably have to create a special "home page" .twig file or perhaps a layout inside pyro.

Update 2

Doesn't look like you can put code into the database or the site will 500 with "Twig_Error_Syntax: Unknown "posts" tag" which I guess is a limitation of using a templating engine that works with files. I do wonder if the layouts for page "types" could be cached as .twig files in storage?

Ya the WYSIWYG might format some things kinda funny as a sanitary action (which results in 500 I assume in your case). I would never advise putting code into the editor. You can use grid to safely allow adding HTML to a page or even as a partial so the client never sees it. But a homepage page type would be another good option.

Entries is a core function for the streams platform that let's you access any stream data you want: https://pyrocms.com/documentation/streams-plugin/latest#usage/entries

PS entries('posts') is short for entries('posts', 'posts'). Since they're the same you can just provide the namespace since the slug is the same.

And you can route the home page to the posts module by adding a route like:

Route::get('/', 'Anomaly\PostsModule\Http\Controller\[email protected]');

Just like the module does basically. Since the Route::get('/', 'Anomaly\PostsModule\Http\Controller\[email protected]'); file is loaded last you can create it / add this route to them to override all prior defined routes.

Ok so the entries( ) arguments are pretty much

entries("namespace","table")

And the system does cache layouts and code in the storage directory. For me I created a page type called "code" that has a field type that is a twig editor which i pasted the snipet of code from the top into and out came the errors:

[2017-05-04 02:05:52] local.CRITICAL: Symfony\Component\Debug\Exception\FatalErrorException: Method Anomaly\EditorFieldType\EditorFieldTypePresenter::__toString() must not throw an exception, caught Twig_Error_Syntax: Unknown "posts" tag in "/Users/admin/www/websitename/storage/streams/default/pages/home_page_pages/3/code.twig" at line 1. in /Users/admin/www/websitename/vendor/twig/twig/lib/Twig/Extension/Core.php:0
Stack trace:
#0 {main} {"identification":{"id":"f998960b-d8c0-4aa9-91e2-28f391ffae02"}} 

So you can go to the file location /code.twig and edit it in a normal editor. I assume it gets overwritten by a database edit though. The error might be related to my layout which just has a {{ page.code }} tag in it, but I guess it's an object and it needs to be {{ page.code | render }} or something.

Looks like the syntax for the code page is something like

{{ page.codefieldname.render }} or {{ page.codefieldname.rendered }} 

Which corespond to function names in the EditorFieldTypePresenter class. Seems that the .rendered() is deprecated so I'm going with .render. That gives me:

Twig_Error_Syntax: Unknown "posts" tag in "/Users/admin/www/websitename/storage/streams/default/pages/home_page_pages/3/code.twig" at line 1. in /Users/admin/www/website/vendor/twig/twig/lib/Twig/Parser.php:181

I'm wondering if the code snippet can't just be placed in a page. If I put some HTML in the box it renders the content out as a quoted string with any of {{ page.code.content }} {{ page.code.render }} which is weird. The syntax is definately twig but I've never used it before so I'm giving up on that whole approach and going to look into routes.

So routes... It's not the routes/web.php file seeing as that still seems to be pointing at the laravel welcome page. So I'm looking around for a routes.php or web.php file first, and then I'm going to look for something that starts with

Route::get('/', 'Anomaly\PagesModule\Http\Controller\PagesController

Because something like that is currently being called to have the site in the state that it is currently in. Hopefully I can edit that location. There's a PublishRoutes console command which looks like it generates a simple get request route to a "welcome" view and puts it in the resources folder. Apparently that didn't run during my setup. I created the file manually but that didn't seem to do anything.

Running vendor:publish CLI command did publish a few vendor files but they all seemed to be part of other Laravel packages. I found a class called IncludeRoutes which again tries to run the getResourcesPath('routes.php') so i thought I would do a dd() on that command and see where it is evaluating. It's not going to the resources directory, it's going to /resources/default/routes.php, that directory doesn't even exist. After manually creating the folder, file and putting in Ryan's code from above I have got a website with the posts module as the home page.

What's the content of code in your page?

ryanthompson - 2 months ago

entries("namespace","stream_slug")

Is the proper syntax. Your error says you've got Twig syntax issue in there so paste that and we'll be set.

You're spot on on the render btw: entries("namespace","stream_slug") . {{ page.field_slug.render|raw }} is the same thing but it uses {{ page.field_slug|raw }} magic to return __toString() which will hide errors since render() is not allowed to throw exceptions in PHP. So for best results use the __toString() one.

Yeah I'm still a little mystified about that one. Seeing as I'm the only person editing the site I'd probably drop quite a bit of code into the GUI.

{% posts = entries('posts').paginate() %}
{% for post in posts %}
    <p>
        {{ post.title }}
    </p>
{% endfor %}
{{ posts.links|raw }}

ryanthompson - 2 months ago

You're close! You need to use set:

{% set posts = entries('posts').paginate() %}

OK, looks like the docs are missing it here:

https://pyrocms.com/documentation/streams-plugin/latest#usage

I'd submit a PR but I don't know where you keep these

ryanthompson - 2 months ago

Thanks, fixed! Must have been a long night cause there were multiple of that set missing in there - no repo for docs just mention it to me like this ^_^
