The intent is to assign all activity & records from user A to user B. This will give the effect of user B seeming to have done everything both users have ever done in Moodle.

This tool replaces the old report_mergeusers, which is now obsolete.

    Hi!

    Thanks Constance for the reply.

    Hi Beto. This plugin is a Moodle plugin. As such, it only operates on the Moodle database, and not on external databases.

    Thanks to all of you.

    Moodle 3.5 compatible and no privacy provider?

    As a result the phpunit tests fail:

    provider_testcase::test_all_providers_compliant with data set "tool_mergeusers" ('tool_mergeusers', 'tool_mergeusers\privacy\provider')
    Failed asserting that false is true.

    privacy/tests/provider_test.php:178
    ips/lib/phpunit/classes/advanced_testcase.php:80

    To re-run:
    vendor/bin/phpunit provider_testcase privacy/tests/provider_test.php

    You're right. Sorry about that. We will check it.

    I used your tool to try to combine two accounts. However, an error is returned, and I was hoping to get some input on what it means.

    Exception thrown when merging: 'Error reading from database"
    Table 'moodle.mdl_ast_access1095' doesn't exist

    I looked through the tables listed on moodle's site (for reference) and the ones I can see in MySQL workbench, and that table doesn't exist.

    Does that mean that the tool is looking for that table, can't find it, and is throwing an error? Is there anything I can do to work around this issue?

    Hi Zackary!

    Thanks for reporting.

    It is very very weird that this plugin tries to look for a table that actually does not exist. Most of all because it looks for all tables in runtime and then iterates for all of them.

    However, if this is the case (we should take a look why it is happenning), you can take a turnaround and let the plugin prevent processing that table. Let's see:

    Taking a look at what we talk about here: https://github.com/ndunand/moodle-tool_mergeusers we can add ad-hoc configuration for every Moodle instance independently.

    I recommend you to place the file "admin/tool/mergeusers/config/config.local.php" with the following content:

    ========================= <?php

    return array(
    'exceptions' => array(
    'ast_access1095', //don't place the table prefix on the table name
    ),
    );
    =========================

    If you have this file already created, for whatever reason, you should have to merge the content. Otherwise, you just create the file with the above content.

    Just tell us what it's going on!

    Jordi

    Sorry, the content should be this (without the "=" strings):

    =========================

    <?php

    return array(
    'exceptions' => array(
    'ast_access1095', //don't place the table prefix on the table name
    ),
    );

    =========================

    Hope that helps!

    Thank you Jordi! Adding that exception did the trick. So simple and effective.

    Jordi, we have used the merge users plugin for a while (since it was a report). We just noticed that it is not merging grades within a gradebook when both of the student accounts were enrolled. We are on Moodle version 3.5.0. There are no errors or anything within debugging to indicate that something is wrong that I can see.

    • Is this the intended outcome? I might have missed that the plugin always did this in the past, and just thought it was merging them. I attempted to rollback the plugin, and that made no difference.

    • Right now, our log output for a merge shows these two lines related to grades:
    DELETE FROM mdl_grade_grades WHERE id IN (38548, 38547, 38549)
    UPDATE mdl_grade_grades_history SET userid = '9232' WHERE id IN (137943, 137944, 137945, 137946)

    Do I have a setting incorrect? I have been leaving the default settings for the plugin, as they have worked for me in the past.

    Thank you

    Hi @Evan!

    Thanks for giving us feedback.

    Please, check if this issue is related to your case: https://github.com/ndunand/moodle-tool_mergeusers/issues/93

    If so, add there your comments to get them there and be complementary to what already exists. Otherwise, in case of doubt, make a new issue with your text.

    Depending on what matches best, it may be an underlying bug long time existing or it may be a new issue for working it on Moodle 3.5. Your information there would be necessary to match the case. Put that information, please, on github.

    Thank you for sharing,

    Jordi

    I used your tool to try to combine two accounts. It appears to have worked however when the user attempted to run a grade report it gave the following error :

    Debug info:
    Error code: nopermissions

    Stack trace:
    line 808 of /lib/accesslib.php: required_capability_exception thrown
    line 65 of /grade/report/grader/index.php: call to require_capability()

    The role for this user in this course hasn't changed and is ARCHETYPE: Teacher (editing).

    Any input would be appreciated.

    Hi!

    Thanks for reporting.

    This sound very strange. This is something totally new.

    There should not be any problem about merging two accounts, if both are teacher (editing teacher).

    I would like to give you more feedback, but we need more detail on this.

    I propose you to start a new issue in our Github project: https://github.com/ndunand/moodle-tool_mergeusers/issues/new, so that we keep a single discussion, without mixups, on this issue. Please, on the new issue at github, report the above information and the log (as much as possible) for the merged users (as a text file or so -copy&paste- big grin ).

    Thank you so much for your time Trish!

    Jordi
