I have 2 database tables:
tx_pg_domain_model_item
fe_groups
It is possible to assign various groups to an item, so in my TCA for tx_pg_domain_model_item it looks something like this:
'groups' => array(
'exclude' => 1,
'label' => 'groups',
'config' => array(
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'fe_groups',
'MM' => 'tx_pg_item_groups_group_mm',
'size' => 5,
'minitems' => 0,
'maxitems' => 9999,
),
),
The problem is, there are a lot of groups and so as the database grew bigger and bigger recently trying to edit an item in the backend no longer worked. I looked at the errorlog and it says this:
PHP Fatal error: Allowed memory size of 268435456 bytes exhausted
now my question is: is there another way to do this to make this work? Some kind of lazy loading maybe or can you guys think of any other alternative?
You should better use group instead of select.
select loads all fe_users while loading your form in the backend. If you have too much users, there will be this memory fatal error.
You have to increase your php memory_limit into your php.ini file.
for eg.
; Old Limit
; memory_limit = 512M
; New Limit
memory_limit = 1048M
then again restart your apache server.

'passwordtype' => [
'exclude' => false,
'label' => '###label####',
'config' => [
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'passwordtypes',
'foreign_sortby' => 'name',
],
],
That part of the tca works like a charm. The passwordtypes are getting sorted by name when I open the record of a password in the backend.
But I want the sorting of the passwordrecords also happening by the passwordtypes. So I tried 'sortby' => 'passwordtype' under 'ctrl' but that only sorts it by the uid, not by the name of the passwordtypes.
I also tried 'sortby' => 'passwordtype.name' but that creates an error. Is it possible to sort it by the name of passwordtypes instead of the uid? It clearly has the name of the passwordtypes already in the passwordlist because when I change the 'label' under 'ctrl' to 'passwordtype' than I can see the correct names and not uids.
I'm open for every idea even if I have to change my database-structure.
Let's dive into the core...
The record lists are generated via \TYPO3\CMS\Recordlist\Controller\RecordListController::main(). Fot getting the list itself, the method calls
\TYPO3\CMS\Recordlist\RecordList\DatabaseRecordList::generateList().
generateList() does select data only from the actual table itself. No relations are resolved here. Then it becomes clearer why sorting by fields of a relation is not possible: they are not part of the selected data.
But... The labels of foreign records are shown.
Yes, that's done while rendering a concrete row of the list. At that
moment, no sorting can be applied anymore.
But... It works for sorting by UIDs.
Yes and no. You have a 1:n relation, so the UID of the foreign record
is saved as foreign_key in your (passwordrecords) table. The
'sortby' => 'passwordtype' is not applied to the table
passwordtype but to the column passwordrecords.passwordtype containing these UIDs.
Conclusion:
Out of the box, there seems not to be an option for sorting by a foreign table field.
Maybe, you can hook into the recordlist by \TYPO3\CMS\Backend\RecordList\RecordListGetTableHookInterface::getDBlistQuery() (called in \TYPO3\CMS\Recordlist\RecordList\DatabaseRecordList::getTable) and modify the query parts to meet your needs.
Simply put the order in are foreign_table_where:
'passwordtype' => [
'exclude' => false,
'label' => '###label####',
'config' => [
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'passwordtypes',
'foreign_table_where' => 'AND 1=1 ORDER BY name',
],
],
I'm trying to add a column to the relation table (MM table) in Typo3. Let's say I have my tables user, wanted_car and wanted_car_mm which is my relation table. So in wanted_car_mm I'll know what user want which car, but I want to add the column need_faster in wanted_car_mm, which is a boolean, that tells me who should have it faster. A lot of users could need it faster, there's no order.
How do I add this column, map the value and correctly retrieve this information when I get all my users?
I currently have this in my TCA config for user:
'wanted_cars' => array(
'exclude' => 1,
'label' => 'LLL:EXT:caa_my_plugin/Resources/Private/Language/locallang_db.xlf:my_title',
'l10n_mode' => 'exclude',
'config' => array(
'type' => 'select',
'foreign_table' => 'wanted_car',
'MM' => 'wanted_car_mm',
'MM_insert_fields' => array('need_faster' => '???'),
'MM_table_where' => ' AND wanted_car_mm.need_faster = ???',
'maxitems' => 9999,
'multiple' => 0,
'renderType' => 'selectCheckBox',
),
),
I feel like this is how I should add the column and retrieve it correctly, but I have no clue how to map the correct value.. that I should also put in my where clause.. I don't know how this can be possible going like this, but I can't find any other way of doing it.
The value must be specified when creating a user.
You need an intermediate table for that. The full docs for that can be found on https://docs.typo3.org/m/typo3/reference-tca/master/en-us/ColumnsConfig/Type/Inline.html
a screenshot and old example which still should work can also be found on https://wiki.typo3.org/Inline_Relational_Record_Editing_Attributes
I've been trying to extend tx_news with a m:m relation with not much luck so far. Anything I can find online is just for a regular relation, where the ID is saved directly into the same table, not an extra _mm column.
The backend looks fine so far, the way I want it with a selectMultipleSideBySide renderType. It also saves the relations to the database.
Extending the News TCA with this, works fine:
$extendArtistId = array(
'artist_id' => array (
'exclude' => 0,
'l10n_mode' => 'exclude',
'label' => 'Künstler',
'config' => array(
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'enableMultiSelectFilterTextfield' => TRUE,
'foreign_table' => 'tx_bfartistmanagement_domain_model_kuenstler',
'foreign_table_where' => 'AND tx_bfartistmanagement_domain_model_kuenstler.sys_language_uid = 0 AND tx_bfartistmanagement_domain_model_kuenstler.pid = 63 ORDER BY tx_bfartistmanagement_domain_model_kuenstler.name ASC',
'MM' => 'tx_news_domain_model_news_artist_id_mm',
'minitems' => 0,
'maxitems' => 99
),
),
);
And the entries are saved the way I expected:
The problem I'm having now is getting these relations from a different extension. News has something called "Hooks", but I'm not sure I want/need that for my case.
The query inside my other extension currently looks like this, newsRepository being injected:
$news = $this->newsRepository->findByArtistId(intval($userID));
I struggle with the next step(s). The function findByArtistId was working before as I was saving the artistId directly inside the news table, but that only works with a direct relation, not an M:M one.
How can I get the News that are associated with that artist, with an m:m relation?
TLDR:
I've got two models with MM-Relations with different StoragePids defined via Constants in my template.
I don't know how to filter results while querying my data regarding my configured storagePids for my related Model.
Long version:
In my multisite-TYPO3 installation I've got two models "Person" and "PersonalInformation". These models have a MM-Relation defined via TCA.
"Person" contains all general data, stored in a global RecordStore. "PersonalInformation" contains editable Data i.e. images to be editable for each site separately. These data are stored in seperate RecordStores under each site.
That means within each site-template->Constants I've defined the extension-storagePid i.e.: $plugin.tx_myext.persistence.storagePid = 1
This config is on all sites the same, to be able to access the same RecordStore from each Site.
The RecordStore for "PersonalInformation" should be different for each site. So my setup.txt of my extension looks like:
persistence {
storagePid = {$plugin.tx_myext.persistence.storagePid},
{$plugin.tx_tx_myext.persistence.personalInformationStoragePid}
classes {
TYPO3\T3myext\Domain\Model\PersonalInformation {
newRecordStoragePid = {$plugin.tx_myext.persistence.personalInformationStoragePid}
}
}
}
And in my root-site-template under Constants I've defined plugin.tx_myext.persistence.personalInformationStoragePid for each site individually.
My TCA MM-Relation defined for PersonalInformation:
'person' => array(
'exclude' => 1,
'label' => 'LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_person',
'config' => array(
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'tx_myext_domain_model_person',
'foreign_table_where' => 'AND 1=1 ORDER BY last_name ASC',
'MM' => 'tx_myext_person_personalinformation_mm',
'size' => 10,
'autoSizeMax' => 30,
'maxitems' => 1,
'minitems' => 0,
'multiple' => 0,
),
),
My TCA MM-Relation defined for Person:
'personalinformation' => array(
'exclude' => 1,
'label' => 'LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_person.personalinformation',
'config' => array(
'type' => 'none',
'readonly' => 1,
'foreign_table' => 'tx_myext_domain_model_personalinformation',
'MM_opposite_field' => 'personalinformation',
'MM' => 'tx_myext_person_personalinformation_mm',
'foreign_table_where' => 'AND tx_myext_domain_model_personalinformation.pid=###The-PID-defined-in-my-site-Const-for-personalInformationStoragePid###'
),
),
If I var_dump my Person in the Frontend all Person.PersonaInformation of all RecordStores are displayed. But I what to show only PersonalInformation Records of the current Site.
The field in the model will always give back all relations, independent of the storage pid. The foreign_table_where in TCA is only for the backend, so this will do nothing for the frontend.
If you want to only get relations from a certain pid, there are several solutions:
Filter it yourself, either in your template, model or controller. Just loop through the relations and check the pid. This option is easiest, but will be slow if you have a lot of relations.
Select the PersonalInformation records separately in your controller using a PersonalInformationRepository with a findByPerson function. This will respect the storagePid set in TypoScript. This will work fine if you only need the information for 1 person. If you need it for multiple persons on 1 page (in a list view for example) you can do this in a custom getPersonalInformation function in your Person model. If it's not cached it could also be slow for lists (depending on the amount of records).
Use a completely custom query using QueryBuilder (https://docs.typo3.org/typo3cms/CoreApiReference/latest/ApiOverview/Database/QueryBuilder/Index.html). This way you can do it in 1 query with joins.
What is the best solution depends on your exact situation and the number of records.
I wrote a backendmodule with extbase in typo3 4.5 and I would like to show different extbase models for different usergroups, but I don't know how. My idea was to register one backendmodul per usergroup, but i think its too laborious. I don't want to check the user group and their rights in my extension. Is there a way to get this?
Example:
models | usergroup: editor could see
specific models | usergroup: specific_editor could see
Please explain the scenario in details. From this i can say this is possible . All you do see to check the user group and according to this you can create a switchable actions in your controller .
What about having a few checkboxes in extension manager - extension configuration tab for selecting the user group and their rights in your extension?
I try to show different extbase-model-entries to different users in my own backend-modul. For example user 'editor' only see 'entry1' and 'special_editor' see 'entry2' and 'entry3'. My idea was to extend the usergroup tca and add a selectfield for my models. My backend-modul will check the current backenduser to get his usergroup and than i want to check the assigned model. It seems to be laborious, but i think its the best and the only way.
I get one solution:
At first i add a field to be_users.
$tempColumns = array(
'model' => array(
'exclude' => 0,
'l10n_mode' => 'mergeIfNotBlank',
'label' => 'LLL:EXT:extensionResources/Private/Language/locallang_db.xml:tx_extension_domain_model_ownmodel',
'config' => array(
'type' => 'select',
'foreign_table' => 'tx_extension_domain_model_ownmodel',
'size' => 10,
'width' => 20,
'minitems' => 0,
'maxitems' => 9999,
'allowNonIdValues' => 0,
'eval' => 'required',
),
),
);
t3lib_div::loadTCA('be_users');
t3lib_extMgm::addTCAcolumns('be_users',$tempColumns,1);
t3lib_extMgm::addToAllTCAtypes('be_users','model;;;;1-1-1');
in my backend-modul i check the current backenduser
$GLOBALS['BE_USER']->user['model']
so i get a list of my modelids separated by commas.
thats it.
