We have a collection which stores a list of sub objects:
{
_id: MongoID,
title: 'Some title',
items: [
{
sub_type: 'MongoId'
}
]
}
Annoyingly it turns out we've been storing the item.sub_type as both MongoId Objects and as strings.
I've created a query to find all the string versions: (I'm using a regex as some old items were just numbers instead of Ids, they can be ignored).
$query = array(
'items' => array(
'$elemMatch' => array(
'sub_type' => array(
'$type' => 2,
'$regex' => new MongoRegex('/^[a-f\d]{24}$/i')
)
)
)
);
$results = $mongo->collection->find( $query );
I'm now trying to come up with the best way to convert these to MongoIds. I can easily loop through them in PHP and update them, but this seems like a waste.
Is there a better way of doing this?
I just realised I didn't really understand the question. Here goes an update. This one should do it.
Using mongo console...
db.collection.find({}).forEach(function (x) {
x.items.forEach(function (y) {
y.sub_type = ObjectId(y.sub_type);
});
db.collection.save(x);
});
Hi i am working on backend of web application & want to find the documents from mongodb database that contain key active_status with value set to both 1 & 2. With mongodb PHP i am confused of how to find with both parameters in single query.
My query was this:
$mongoDb = MongoDbConnector::getCollection("endusers");
$endUserData = $mongoDb->find(array('active_status' => 1, '$and' => array('active_status' => 2)));
I have to fetch the users whose active_status should be 1 & 2. The above query doesnt seems to work. What is the right one for that?
Thanks on advance for quick response.
You have $and the wrong way around. Both arguments need to be included:
$endUserData = $mongoDb->find(array(
'$and' => array(
array( 'active_status' => 1 )
array( 'active_status' => 2 )
)
));
And since that would only make sense when looking for both elements within an array element, then you should instead use $all, which is shorter syntax:
$endUserData = $mongoDb->find(array(
'active_status' => array( '$all' => array(1,2) )
));
I should add that unless you intend to match a document like this:
{ "active_status" => [1,2] }
The you do not in fact want $and at all, but rather you want $or or better yet $in for multiple possible values on the same field:
$endUserData = $mongoDb->find(array(
'active_status' => array( '$in' => array(1,2) )
));
This matches documents like this:
{ "active_status": 1 },
{ "active_status": 2 }
Can someone provide a sample code chunk of php using the sugarcrm API/nusoap for adding creating an acct. and then linking a lead to the acct?
I've got a sample function that adds a lead, and I can see how to create an acct, but I can't see how to tie a lead to the acct, to simulate the subpanel process in the sugarcrm acct/subpanel process.
thanks
// Create a new Lead, return the SOAP result
function createLead($data)
{
// Parse the data and store it into a name/value list
// which will then pe passed on to Sugar via SOAP
$name_value_list = array();
foreach($data as $key => $value)
array_push($name_value_list, array('name' => $key, 'value' => $value));
// Fire the set_entry call to the Leads module
$result = $this->soap->call('set_entry', array(
'session' => $this->session,
'module_name' => 'Leads',
'name_value_list' => $name_value_list
));
return $result;
}
$result = $sugar->createLead(array(
'lead_source' => 'Web Site',
'lead_source_description' => 'Inquiry form on the website',
'lead_status' => 'New',
'first_name' => $_POST['first_name'],
'last_name' => $_POST['last_name'],
'email1' => $_POST['email'],
'description' => $_POST['message']
));
You need to find the ID for the account and assign that ID to whatever the account_id field name is in the Lead Module. I have run into a couple things like this before and I have found it easier to go straight to the Sugar database. So, write a statement that will return the account is, for example: SELECT id WHERE something_in_the_account_table = something else;
Then you can assign that id in your $result array. I hope it helps. I didn't have any code or documentation in front of me or I would have helped more.
how can I work with lists within the mongoDB?
For example, I have a document (class), and a list of students in this class, ie a subdocument (students).
What do not you, is to add more students to a class.
in Model:
public function salvar($name,$idClass){
$new = array(
"_id" => $idClass,
"student"=> array(
'idStudent' => new MongoId(),
'name' => $name));
return $this->save($new);
}
But when you add a new student, he is not working that way.
How to perform a $push update
The answer you've provided clarifies what you've been trying to do. However, the solution is a little convoluted. To perform a $push update with MongoDB, simply specify you want to perform a push update:
$this->Foo->save(array(
'_id' => $id,
'$push' => array(
"images" => array(
'id' => new MongoId(),
'name' => $name,
'size' => $size
)
)
);
You can use the mongoNoSetOperator property to achieve the same thing but
It's indirect, therefore not obvious
With multiple calls to save in the same request it can be confusing if it's not reset to $set if it's modified
It prevents using multiple operators in a single call.
There's more information about using different update operators in the documentation.
the answer to the question was:
public function salvar($name,$size,$id){
$this->mongoNoSetOperator = '$push';
// fixed array data structure
$susp = array(
"_id" => $id,
"images"=> array(
array(
'id' => new MongoId(),
'name' => $name,
'size' => $size
)
)
);
return $this->save($susp);
}

I usualy use Zend_Validate_Db_RecordExists to update or insert a record. This works fine with one field to check against. How to do it if you have two fields to check?
$validator = new Zend_Validate_Db_RecordExists(
array(
'table' => $this->_name,
'field' => 'id_sector,day_of_week'
)
);
if ($validator->isValid($fields_values['id_sector'],$fields_values['day_of_week'])){
//true
}
I tried it with an array and comma separated list, nothing works... Any help is welcome.

To do this you would have to extend the Zend_Validate_Db_RecordExists class.
It doesn't currently know how to check for the existence of more than one field.
You could just use two different validator instances to check the two fields separately. This is the only work around that I can see right now besides extending it.
If you choose to extend it then you'll have to find some way of passing in all the fields to the constructor ( array seems like a good choice ), and then you'll have to dig into the method that creates the sql query. In this method you'll have to loop over the array of fields that were passed in to the constructor.
You should look into using the exclude parameter. Something like this should do what you want:
$validator = new Zend_Validate_Db_RecordExists(
array(
'table' => $this->_name,
'field' => 'id_sector',
'exclude' => array(
'field' => 'day_of_week',
'value' => $fields_values['day_of_week']
)
);
The exclude field will effectively add to the automatically generated WHERE part to create something equivalent to this:
WHERE `id_sector` = $fields_values['id_sector'] AND `day_of_week` = $fields_values['day_of_week']
Its kind of a hack in that we're using it for the opposite of what it was intended, but its working for me similar to this (I'm using it with Db_NoRecordExists).
Source: Zend_Validate_Db_NoRecordExists example
Sorry for the late reply.
The best option that worked for me is this:
// create an instance of the Zend_Validate_Db_RecordExists class
// pass in the database table name and the first field (as usual)...
$validator = new Zend_Validate_Db_RecordExists(array(
'table' => 'tablename',
'field' => 'first_field'
));
// reset the where clause used by Zend_Validate_Db_RecordExists
$validator->getSelect()->reset('where');
// set again the first field and the second field.
// :value is a named parameter that will be substituted
// by the value passed to the isValid method
$validator->getSelect()->where('first_field = ?', $first_field);
$validator->getSelect()->where('second_field = :value', $second_field);
// add your new record exist based on 2 fields validator to your element.
$element = new Zend_Form_Element_Text('element');
$element->addValidator($validator);
// add the validated element to the form.
$form->addElement($element);
I hope that will help someone :)
Although, I would strongly recommend a neater solution which would be to extend the Zend_Validate_Db_RecordExists class with the above code.
Enjoy!!

$dbAdapter = Zend_Db_Table::getDefaultAdapter();
'validators' => array('EmailAddress', $obj= new Zend_Validate_Db_NoRecordExists(array('adapter'=>$dbAdapter,
'field'=>'email',
'table'=>'user',
'exclude'=>array('field'=>'email','value'=>$this->_options['email'], 'field'=>'is_deleted', 'value'=>'1')
))),
For those using Zend 2, If you want to check if user with given id and email exists in table users, It is possible this way.
First, you create the select object that will be use as parameter for the Zend\Validator\Db\RecordExists object
$select = new Zend\Db\Sql\Select();
$select->from('users')
->where->equalTo('id', $user_id)
->where->equalTo('email', $email);
Now, create RecordExists object and check the existence this way
$validator = new Zend\Validator\Db\RecordExists($select);
$validator->setAdapter($dbAdapter);
if ($validator->isValid($username)) {
echo 'This user is valid';
} else {
//get and display errors
$messages = $validator->getMessages();
foreach ($messages as $message) {
echo "$message\n";
}
}
This sample is from ZF2 official doc
You can use the 'exclude' in this parameter pass the second clause that you want to filter through.
$clause = 'table.field2 = value';
$validator = new Zend_Validate_Db_RecordExists(
array(
'table' => 'table',
'field' => 'field1',
'exclude' => $clause
)
);
if ($validator->isValid('value') {
true;
}
I am using zend framework v.3 and validation via InputFilter(), it uses same validation rules as zend framework 2.
In my case I need to check, if location exists in db (by 'id' field) and has needed company's id ('company_id' field).
I implemented it in next way:
$clause = new Operator('company_id', Operator::OP_EQ, $companyId);
$inputFilter->add([
'name' => 'location_id',
'required' => false,
'filters' => [
['name' => 'StringTrim'],
['name' => 'ToInt'],
],
'validators' => [
[
'name' => 'Int',
],
[
'name' => 'dbRecordExists',
'options' => [
'adapter' => $dbAdapterCore,
'table' => 'locations',
'field' => 'id',
'exclude' => $clause,
'messages' => [
'noRecordFound' => "Location does not exist.",
],
]
],
],
]);
In this case validation will pass, only if 'locations' table has item with columns id == $value and company_id == $companyId, like next:
select * from location where id = ? AND company_id = ?
