The availability condition get_description method is called while
gathering data for the modinfo object. As such it is not safe to
call other functions which might rely on modinfo, such as format_string
(if using filters which access modinfo).
This change provides a mechanism to call format_string later, and also
a general callback to do other stuff later as well if needed. It uses
the same approach already taken to make activity names work correctly
in the availability_condition class.
This class would belong more appropriately within the 'user' API
(core_user) instead of within the 'core' API, since it is
directly related to user data.
Since the class has only just been added to Moodle, now is a good
time to move it.
In all cases changes have been kept to a minimum while not making
the code completely horrible. For example, there are many instances
where it would probably be better to rewrite a query entirely, but
I have not done that (in order to reduce the risk of changes).
1) Get rid of "uid" that is a reserved word.
2) Add cross-db support for text columns in the get_condition_sql() method
by adding a new, defaulting to false for BC param and intensively using
the sql_compare_text() helper to build the correct sql fragments.
As part of the unit test modifications for this change, I added the get_json
function to the availability conditions that didn't have it. (This is a function
for use in unit tests.)
The previous API included a facility to filter a list of users
to include only those who are allowed to access an activity, i.e.
only people who belong to the required groups etc.
This change adds a new API function to return SQL that obtains
this list of users, so that it can be combined with other
queries.
It has never worked, because the data for text area fields is not
loaded into the $USER object.
Changing it so that the dropdown list does not include these types
of field.
Includes all the conditions that were in previous Moodle versions:
* Date
* Grade
* Completion (of another activity)
* User profile field
Also includes conditions that are used to reimplement
groupmembersonly:
* Grouping
* Group
For each condition, the component plus unit tests are included.
PLEASE NOTE: The code to actually check each condition is reused
from previous Moodle versions and has not been modified except to
pass codechecker. This is intentional, to reduce the risk of the
change and maximise the chance that behaviour is preserved. Some
of this code might not be very good and might need updating but
that can happen separately.
