Feature #93450
Updated by Ayke Halder about 3 years ago
h2. Current state
A TypoScript "select":https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/Functions/Select.html object must have at least one constraint of @uid@ or @pid@ - configured via properties "uidInList":https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/Functions/Select.html#uidinlist and "pidInList":https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/Functions/Select.html#pidinlist
h2. Feature proposal
Allow to completely disable the pid_uid constraint on purpose in ContentObjectRenderer.
<pre><code class="javascript">
10 = CONTENT
10 {
table =
select {
uidInList = 0
pidInList = 0
}
}
</code></pre>
h2. Motivation
Get records from a m:n-relation where you already know the @uids@ of one side.
Tables respresenting m:n-relations do not have a field named @uid@ - instead they have @uid_local@ and @uid_foreign@.
As a current work-around you must pre-fill @pidInList@ with *all* @pids@ of the entire database to make this work:
<pre><code class="javascript">
pidInList.data = leveluid : 0
</code></pre>

<pre><code class="javascript">
