How to get value from custom profile field in moodle?
i want to include the profile field in user.php
If you want to load all the user profile fields, then you can start with a user object
$user = $DB->get_record('user', array('id' => $userid));
and then call
profile_load_custom_fields($user);
to fill in the $user->profile with an array of all the custom fields.
Alternatively, you can get the contents of a single profile field via:
$sql = "SELECT ud.data
FROM {user_info_data} ud
JOIN {user_info_field} uf ON uf.id = ud.fieldid
WHERE ud.userid = :userid AND uf.shortname = :fieldname";
$params = array('userid' => $userid, 'fieldname' => 'NameOfCustomField');
$fieldvalue = $DB->get_field_sql($sql, $params);
Note this code is written off the top of my head and untested, so it may have some typos in it.
You can use:
$Data = $USER->profile['YourCustomField'];
I finally made it!!!
$sql = 'SELECT DISTINCT u.id AS userid, u.username, uif.shortname, uid.data FROM prefix_user u JOIN prefix_user_info_data as uid on uid.userid = u.id JOIN prefix_user_info_field as uif on uid.fieldid = uif.id JOIN prefix_user_enrolments ue ON ue.userid = u.id JOIN prefix_enrol e
ON e.id = ue.enrolid JOIN prefix_role_assignments ra ON ra.userid = u.id JOIN prefix_context ct ON ct.id = ra.contextid AND
ct.contextlevel = 50 JOIN prefix_course c ON c.id = ct.instanceid AND e.courseid = c.id JOIN prefix_role r ON r.id = ra.roleid
where uif.shortname = \'fieldname\' and u.id ='.$userid;
$records = $DB->get_recordset_sql($sql, array(), $params=null, $limitfrom=0, $limitnum=0);
foreach($records as $record){
$user['fieldname'] = $record->data;
}
custom fields are stored in 'user_info_field' table and data for each field and user are stored in 'user_info_data' table then you should know your fieldid in database and select data based on this id:
$field = $DB->get_record('user_info_field', array('shortname' => 'customfieldshortname'));
$fieldvalues = $DB->get_records('user_info_data',array('fieldid' => $field->id));
i hope my solutions help anybody:
need this lib
require_once($CFG->dirroot.'/user/profile/lib.php');
and now you can use:
profile_load_data($USER);
$USER->profile_field_%your_field_name%
example $USER->profile_field_HaveAnotherGradeBook;

I have an sql query like this:-
SELECT * FROM `permissions` join entities where NOT EXISTS (select
entity_id,permission_id from role_permissions where role_id=5 and
entities.id = role_permissions.entity_id and permissions.id =
role_permissions.permission_id)
I would like to get the corresponding rails query.
I have tried this.
Permission.joins("join entities").joins("LEFT OUTER JOIN role_permissions on
permission_id != permissions.id and entities.id != entity_id and
role_permissions.role_id= role_id").select("role_permissions.entity_id,role_permissions.role_id,
role_permissions.permission_id").group('role_permissions.entity_id,
role_permissions.permission_id')
But it doesn't works.
thanks

I have been particularly in love with EXISTS queries lately, precisely because it does not require you to fully join another table. As far as I know, you do have to explicitly write the SQL clause, but you can still make it work with Activerecord. You can even put this in a scope within a lambda block.
Permission.joins(:entities).where(<<-SQL
NOT EXISTS(
select
* from role_permissions where role_id=#{your_role_id} and
entities.id = role_permissions.entity_id
and permissions.id = role_permissions.permission_id
)
SQL
)
Try like this for a default SQL query:
sql = "SELECT some_field FROM `permissions` join entities where NOT EXISTS (select entity_id,permission_id from role_permissions where role_id=5 and entities.id = role_permissions.entity_id and permissions.id = role_permissions.permission_id)"
results = ActiveRecord::Base.connection.execute(sql)
results.each do |result|
#register_users << { some_field: result[0] }
end
Try this
UPDATED BASED ON FIRST COMMENT
Permission.joins(:entities).joins("LEFT OUTER JOIN role_permissions on
permission_id != permissions.id and entities.id != entity_id and
role_permissions.role_id= role_id")
.select("role_permissions.entity_id,role_permissions.role_id,
role_permissions.permission_id")
.group('role_permissions.entity_id, role_permissions.permission_id')
SELECT A.FirstName, A.LastName, B.PatientId, B.RoomNumber, B.AdmissionDate, B.DischargeDate, B.MeasureCategory
FROM DimPatient A, DimPatientStay B
WHERE A.Id = B.PatientId AND A.FirstName = 'Anuj' AND B.MeasureCategory = 'ED'
hi some updation for this
i solved this prob by
MODELNAME.find_by_sql("your sql query")
You can try this to find the result from sql query in Rails
query_params = Hash.new
sql_query = "SELECT A.FirstName, A.LastName, B.PatientId, B.RoomNumber, B.AdmissionDate, B.DischargeDate, B.MeasureCategory
FROM DimPatient A, DimPatientStay B
WHERE A.Id = B.PatientId AND A.FirstName = :first_name AND B.MeasureCategory = :measure_category"
query_params[:first_name] = first_name
query_params[:measure_category] = measure_category
#query_results = ActiveRecord::Base.connection.select_all(
ActiveRecord::Base.send("sanitize_sql_array",[sql_query, query_params] )
)
I guess you could try:
ActiveRecord::Base.connection().execute(#your_sql_here)
Suppose A is one class and B is another, you should use includes as following:
A.includes(:b).where(...) # add you condition in where

I am doing like this sql into zend framework sql pattern.
SELECT
jobs . *,
c.id AS cid,
c.name AS name,
c.companyImage AS companyImage,
c.logo AS logo,
count(app.userId) AS t_app,
app.applyStatus AS applyStatus,
app.userId AS appUserId
FROM
jobs
LEFT JOIN
companies AS c ON jobs.companyName = c.id
LEFT JOIN
applicants AS app ON jobs.id = app.jobId AND app.applyStatus = 1
WHERE
jobs.ownerId = 16 AND jobs.draftId != 0
GROUP BY jobs.id
ORDER BY jobs.id DESC
LIMIT 3
For this sql I already write this code for zend framework 2
$adapter = $this->tableGateway->getAdapter();
$sql = new Sql($adapter);
$select = $sql->select();
$select->from('jobs')
->join(array('c' => 'companies'), 'jobs.companyName = c.id', array('cid' => 'id', 'name', 'companyImage', 'logo'), 'left')
->join(array('app' => 'applicants'), ' jobs.id = app.jobId AND app.applyStatus = 1', array('t_app' => new Expression('count(app.userId)'), 'applyStatus', 'appUserId' => 'userId'), 'left')
->where("jobs.ownerId ={$userId} AND jobs.draftId != 0")
->group('jobs.id')
->order('jobs.id DESC')
->limit(3);
$statement = $sql->getSqlStringForSqlObject($select);
$results = $adapter->query($statement, $adapter::QUERY_MODE_EXECUTE);
but does not work properly and its give a message like below.
SQLSTATE[42S22]: Column not found: 1054 Unknown column '1' in 'on clause'
The issue is this part:
app.applyStatus = 1
The framework is escaping 1 as if it were a column name, 1.
You need to enclose this part in an Expression too
new Expression('jobs.id = app.jobId AND app.applyStatus = 1')
I think the use of Expressions in the 'ON' parameter of the join method may depend on the version of ZF2 you are using, I think it was added 2.1+
Building on this answer. If you also want your table & column identifiers to be escaped, use this syntax:
use Zend\Db\Sql\Expression;
...
$onExpression = new Expression('? = ? AND ? = ?',
['jobs.id', 'app.jobId', 'app.applyStatus', 1],
[Expression::TYPE_IDENTIFIER, Expression::TYPE_IDENTIFIER,
Expression::TYPE_IDENTIFIER, Expression::TYPE_LITERAL]
);
$select->from('jobs')
->join(array('app' => 'applicants'), $onExpression, array('t_app' => new Expression('count(app.userId)'), 'applyStatus', 'appUserId' => 'userId'), 'left');
The Expression constructor accepts the string, then arguments, then argument types.
public function __construct($expression = '', $parameters = null, array $types = [])
This will create a security issue. Zf2 changes your query to this:
Select * from tableA inner join tableB
on `tableA`.`column` = `tableB`.`column`
AND `tableB`.`column` = `1`
It adds
`
to each part for security issues! By using new Expression you are bypassing it and if you get applyStatus from user entry, get sure about its filtering!
How would you write this line in the "rails way"?
unique_attendees = CourseSessionsUser.count_by_sql(["SELECT count(DISTINCT csu.user_id) AS count_user_id FROM course_sessions_users csu, course_sessions cs WHERE cs.course_id = ? AND csu.course_session_id = cs.id"], #course.id)
The query itself is:
SELECT count(DISTINCT csu.user_id) AS count_user_id
FROM course_sessions_users csu,
course_sessions cs
WHERE cs.course_id = ?
AND csu.course_session_id = cs.id
Use count method of the rails
count = CourseSessionsUser.count('csu.user_id',
:distinct => true, :conditions => ["cs.course_id = ?", #course.id]
:joins => "cs LEFT JOIN course_sessions_users csu ON cs.id = csu.course_session_id")
This will return directly non zero integer if condition matches otherwise return zero
I have the following tables: users(id), articles(id), favorites(article_id, user_id). I need to list articles added to favorites by current user with a flag indicating if they were also favorited by other users. SQL is quite simple:
select articles.id, count(f2.article_id)
from articles a
inner join favorites f1 on f1.article_id = a.id
left join favorites f2 on f1.article_id = f2.article_id and not f1.user_id = f2.user_id
where f1.user_id = 1
group by a.id
Is there a way to do it using Rails query generator?
something like this should get you on your way (assuming you have an Article and Favorites model/table):
t = Article.joins("INNER JOIN #{Favorite.table_name} AS f1 on f1.article_id = #{Article.table_name}.id")
t = t.joins("LEFT JOIN #{Favorite.table_name} AS f2 on f1.article_id = f2.article_id AND NOT f1.user_id = f2.user_id")
t = t.where("f1.user_id = ?", 1)
t = t.group("#{Article.table_name}.id")
t.select("#{Article.table_name}.id, COUNT(f2.article_id)")
