Migrating from v2 to v3 - how to substitute 'relate' tag

[cmorierroy]

Hi, I'm migrating a site from v2 to v3 and most things work so far.
I am running into problems with the relate tag - I know it's a breaking change, but the augmentation part of the doc confuses me.

This is what the original code looked like, country being an entry field on location entries.

{{ collection:location scope="loc" }}
    {{ relate:country }}
        {{if country=="e69a915e-c26f-4f0a-a6ae-762ef6ec80c0"}}
            <a onclick="locationSelected('{{ loc:slug }}')" href="/{{ loc:slug }}">{{ loc:title }}</a><br>
        {{/if}}
    {{ /relate:country }}
{{ /collection:location }}

What I have now (doesn't show anything, but doesn't throw an error):

{{ collection:location scope="loc" }}
    {{ if loc:country=="canada" }}
        <a onclick="locationSelected('{{ loc:slug }}')" href="/{{ loc:slug }}">{{ loc:title }}</a><br>
    {{/if}}
{{ /collection:location }}

I'm aware that my condition might not be correct, but it's something like that I'm hoping to achieve, or {{ loc:country:name }}.
Within {{ collection:location scope="loc" }}, {{ loc:country }} doesn't give me anything, as well as {{ country }}.
However, things like {{ loc:name }} work.

Any ideas for how I would fix this? I'm just trying to access the country entry on each location entry.

Does your country field have max_items: 1 on it?
If you intend for it to be a single entry, you'll need that.

[cmorierroy]

Yes it does.

[jasonvarga]

Did your original code not work?

[cmorierroy]

The original code throws this:

Facade\Ignition\Exceptions\ViewException
addcslashes(): Argument #1 ($string) must be of type string, Statamic\Query\OrderedQueryBuilder given

I figure it's due to using the relate keyword

[jasonvarga]

Oh! That looks like something I fixed recently. You didn't mention you were trying to use the 3.3 beta.

#5461

I haven't tagged it yet, it'll be in the next release.

[cmorierroy]

That's gotta be it. Sorry, I did not notice I was on beta, but yes, I'm definitely on 3.3 now that I'm checking.

[cmorierroy]

Well... I deleted the country fieldset from the location collection and re-added it.
Now things work! Maybe something migrated weirdly?
Things work as in, this syntax works:

{{ collection:location scope="loc" }}
    {{if country:slug == "canada"}}
        <a onclick="locationSelected('{{ loc:slug }}')" href="/{{ loc:slug }}">{{ loc:title }}</a><br>
    {{/if}}
{{ /collection:location }}

Do you have a diff of the before/after?

[cmorierroy]

[jackmcdade]

i wonder if it's the mode: tags vs mode: default?

[jasonvarga]

My guess is max_items: '1' vs. max_items: 1
