Locomotive CMS: Dynamically Target content_types with Liquid Variable

问题

I'm building a custom navigation snippet in Locomotive CMS and I want content_type entries to be listed in the navigation along with pages.

Specifically (and obviously) I only want entries listed if the content_type has a content_type_template set up.

My plan was to set a handle (refereneced here but ultimately missing from the documentation) on the content_type_template page and then run the following logic when iterating through pages:

{% assign myContentType = loopPage.handle %}

{% for item in contents.myContentType %}

    <li>a href="{{ item._slug }}">{{ item.name }}</a></li>

{% endfor %}

But I've run into a problem: It seems I can't use a variable in this way. I assume there's some kind of issue with trying to plug a variable with a string value in place of a content_type slug. I wouldn't have thought it would be a problem, but it doesn't work.

I also tried:

{% for item in contents[myContentType] %}

and just to be sure:

{% for item in contents[myContentType].items %}

No joy.

How can I dynamically target content_types in Locomotive CMS using a Liquid variable?

回答1:

Apparently you can't use a Liquid Variable to dynamically target content_types in Locomotive CMS. Specifically, this won't work:

{% assign myVariable = some_string_that_is_the_same_as_a_content_type_slug %}

{% for item in contents.myVariable %}

I tried a number of methods and came to the conclusion that either:

Liquid syntax simply doesn't accept a varibale in this context, or
the Locomotive CMS implementation of Liquid doesn't facilitate it.

(I'd welcome confirmation or clarification on this point as I'm drawing on anecdotal evidence, not documentation.)

In the end, however, I was able to access content_type entries dynamically using the Locomotive CMS RESTful API. This is largely undocumented and a completely separate topic - one which warranted its own Q & A, which I have created here.

Below is the code I used to dynmically access content_type entries. (For brevity I have included only this snippet which sits inside a number of Liquid loops to build the menu items and sub items.)

{% assign myContentType = loopPage.handle %}

{% action "get content_type entries" %}
    var contentData = false;
    contentData = callAPI('GET', 'https://station.locomotive.works/locomotive/api/v3/content_types/{{ myContentType }}/entries.json', {
        data: {
        },
        headers: {
            'X-Locomotive-Account-Email': '[my-account-email-adddress]',
            'X-Locomotive-Site-Handle': '[my-site-handle]',
            'X-Locomotive-Account-Token': '[my-account-token]'
        }
    });
    setProp('contentData', contentData);
{% endaction %}

{% for item in contentData.data %}

    <li><a href="{{ item._slug}}">{{ item.name }}</a></li>

{% endfor %}
