I am new to MongoDB and trying to perform my first updates.
I have my users collection that is populated by an insert statement. Now, I want to add or insert the field authCode with some data into a specific user.
My problem is that when I perform the following function the whole user data becomes replaced by the information in that update statement. My understanding is that by using upsert I would insert or update a users collection. given that the user already exist I expect just the authCode field to be created or updated.
Could anyone point out what am i doing wrong?
public function addAuthCode( array $userId, $code ) {
$user = $this->db()->user;
$user->update(
$userId,
array( 'authCode' => $code ),
array( 'upsert' => true, 'safe' => true )
);
}
You'll want to take a look at the MongoDB documentation for updates found here: http://docs.mongodb.org/manual/reference/method/db.collection.update/#db.collection.update
Specifically:
Add New Fields
db.bios.update(
{ _id: 3 },
{ $set: {
mbranch: "Navy",
"name.aka": "Amazing Grace"
}
}
)
Notice that in order to add a field, you need to use the $set operator

I've been searching the web a lot for clues but can't seem to find any...
public function createNew($name, $type, $restriction,$picture){
global $connection;
$trans=new Transaction($connection,array( 'collections' => array( 'write' => array( 'group_relations','groups' ),'read'=> array( 'group_relations','groups' ) ), 'waitForSync' => true ));
$trans->setAction('function(){
var db= require("#arangodb").db;
var arr=db.groups.insert({"name":"'.$name.'","type":"'.$type.'","restriction":"'.$restriction.'","picture":"'.$picture.'"}).toArray();
db.group_relations.insert({"_from":"users/'.$_SESSION['uid'].'","_to":"groups/"+arr[0]["_id"],"status":"admin"});
}');
$trans->execute();
}
this is a PHP function that makes a transaction. In the transaction, I'm trying to create a group, get its id and insert it in the relation collection between the creator and the new group.
Basically make the creator of the group the admin.
"Fatal error: Uncaught triagens\ArangoDb\ServerException: 17 db.groups.insert(...).toArray is not a function".
Any solutions?
The result of insert({...}) is always an object. The result of insert([{...},{...},...,{...}]) is always an array. In either case .toArray() does not help.
So if you'd like to make sure, that you have an array as a result type, please use the array insert also for single entries:
var arr=db.groups.insert(
[{"name":"'.$name.'",
"type":"'.$type.'",
"restriction":"'.$restriction.'",
"picture":"'.$picture.'"}]);
So in order to get back the ids from your inserts only:
var ids = [];
db.groups.insert([{...},...,{...}]).forEach(
function(obj) {ids.push(obj._id)});
...
I have a problem. I have this structure of db in mongodb:
id:"xxx",
is_validated: "xxx",
validation_code:"xxx",
profile:[
{
profile_pic:"xxx",
firstname:"xxx",
lastname:"xxx",
}
]
I am using cakephp. When I update the record, I use this:
$this->User->set('id', "xxx");
$this->User->set('profile', array('firstname' => 'Benedict'));
$this->User->save()
When I save the record, the whole array of profile is deleted and only saves the "firstname":
id:"xxx",
is_validated: "xxx",
validation_code:"xxx",
profile:[
{
firstname:"xxx"
}
]
I need to be able to save the firstname without deleting the other array records of mongodb using cakephp
Do you not follow the standard convention when using MongoDB? (documentation):
// where '1' is the id of your user
$this->User->read(null, 1);
// set the new value for the field
$this->User->set('profile', array('firstname' => 'Benedict'));
// commit the changes to the database
$this->User->save();
Update
If the above doesn't work, try reading the whole record and modifying accordingly:
// set the active record
$this->User->id = 1;
// read the entire record
$user = $this->User->read();
// modify the field
$user['User']['profile']['firstname'] = 'Benedict';
// save the record
$this->User->save($user);
The reason this is happening is because you are asking for the profile field to be updated with the array that you pass. This then duly replaces the current profile array with yours.
To get round this you will have to pass the complete array in i.e. with the keys you want to keep and their values as well as the keys you want to change.
I have the following code in CakePHP 2:
$this->Order->id = 5;
$this->Order->saveAll(array(
'Order' => array(
'person_id' => $this->Session->read('Person.id'),
'amount' => $total,
'currency_id' => $code
),
'Lineitem' => $lineitems /* a correctly-formatted array */
));
I would expect this to update the row with the Primary Key of 5 in the Order table and then insert the Lineitem rows with an order_id of 5.
However, all it does is create a new row in Order and then use the new id from the new Order record to create the Listitem rows.
Note: I'm only setting the ID as above for debugging purposes and to easily demonstrate this question. In my final code, I'll be checking to see if there's already a pending order with the current person_id and doing $this->Order->id = $var; if there is and $this->Order->create(); if there isn't.
In other words, sometimes I will want it to INSERT (in which case I will issue $this->Order->create(); ) and sometimes I will want it to UPDATE (in which case I will issue $this->Order->id = $var; ). The test case above should produce an UPDATE but it's producing an INSERT instead.
Any idea what I am doing wrong here?
The array you pass to Model->saveAll() doesnt't contain the order's id, so Cake creates a new one. If you wanto to update an existing record, either you set the order id in the passed array, or you retrieve it with a find. The documentation explicitly remarks
If you want to update a value, rather than create a new one, make sure
your are passing the primary key field into the data array
$order = $this->Order->findById(5);
// ... modify $order if needed
$this->Order->saveAll(array('Order' => $order, 'LineItem' => $items));
In your case, you may want to use something like the following to be as concise as possible. Model::saveAssociated() is smart enough to create or update depending on the id, but you must provide suitable input. Model::read($fields, $id) initializes the internal $data: for an existing record all fields will be read from the database, but for a nonexistent id, you'll need to supply the correct data for it to succeed. Assuming an order belongsTo a customer, I supply the customer id if the order doesn't exist
// set the internal Model::$data['Order']
$this->Order->read(null, 5);
// You may want to supply needed information to create
// a new order if it doesn't exist, like the customer
if (! $this->Order->exists()) {
$this->Order->set(array("Customer" => array("id" => $customer_id)));
}
$this->Order->set(array('LineItem' => $items));
$this->Order->saveAssociated();
As a final note, it seems you are implementing a shopping cart. If that's the case, maybe it'd be clearer to use a separate ShoppingCart instead of an Order with a finalized flag.
Have you tried following:
$this->Order->saveAll(array(
'Order' => array(
'id' => 5,
'person_id' => $this->Session->read('Person.id'),
'amount' => $total,
'currency_id' => $code
),
'Lineitem' => $lineitems /* a correctly-formatted array */
));
Its pretty much the same what you did with :
$this->Order->id = 5;
Maybe that would fix your problem.
Cake is checking if you set id field and if its there it updates record, if not found it creates new record instead.
update:
Then maybe check before you saveAll if there is id field, then save result of check to some boolean and create array to save determined by this boolean for example:
if($id_exist) $order['Order']['id'] = 5;
$order['Order']['id'] = 5;
$order['Order']['person_id'] = $this->Session->read('Person.id'),
$order['Order']['amount'] = $total;
$order['Order']['currency_id'] = $code;
$this->Order->saveAll(array(
'Order' => $order,
'Lineitem' => $lineitems /* a correctly-formatted array */
));
I have created a form in which i embed another form. My question is about this embedded form - I'm using a sfWidgetFormDoctrineChoice widget with option multiple set to true. The code for this embedded form's configure method:
public function configure()
{
unset($this['prerequisite_id']);
$this->setWidget('prerequisite_id', new sfWidgetFormDoctrineChoice(array(
'model' => 'Stage',
'query' => Doctrine_Query::create()->select('s.id, s.name')->from('Stage s')->where('s.workflow_id = ?', $this->getOption('workflow_id') ),
'multiple' => true
)));
$this->setValidator('prerequisite_id', new sfValidatorDoctrineChoice(array(
'model' => 'Stage',
'multiple' => true,
'query' => Doctrine_Query::create()->select('s.id, s.name')->from('Stage s')->where('s.workflow_id = ?', $this->getOption('workflow_id') ),
'column' => 'id'
)));
}
I unset the prerequisite_id field because it is included in the base form, but I want it to be a multiple select.
Now, when I added the validator, everything seems to work (it passes the validation), but it seems like it has problems saving the records if there is more than one selection sent.
I get this PHP warning after submitting the form:
Warning: strlen() expects parameter 1 to be string, array given in
D:\Development\www\flow_dms\lib\vendor\symfony\lib\plugins\sfDoctrinePlugin\lib\database\sfDoctrineConnectionProfiler.class.php
on line 198
and more - I know, why - in symfony's debug mode I can see the following in the stack trace:
at Doctrine_Connection->exec('INSERT INTO stage_has_prerequisites
(prerequisite_id, stage_id) VALUES (?, ?)', array(array('12', '79'),
'103'))
So, what Symfony does is send to Doctrine an array of choices - and as I see in the debug sql query, Doctrine cannot render the query correctly.
Any ideas how to fix that? I would need to have two queries generated for two choices:
INSERT INTO stage_has_prerequisites (prerequisite_id, stage_id) VALUES (12, 103);
INSERT INTO stage_has_prerequisites (prerequisite_id, stage_id) VALUES (79, 103);
stage_id is always the same (I mean, it's set outside this form by the form in which it is embedded).
I have spend 4 hours on the problem already, so maybe someone is able to provide some help.
Well, I seem to have found a solution (albeit not the best one, I guess). Hopefully it'll be helpful to somebody.
Finally, after much thinking, I have concluded that if the problem comes from the Doctrine_Record not being able to save the record if it encounters an array instead of a single value, then the easiest solution would be to overwrite the save() method of the Doctrine_Record. And that's what I did:
class StageHasPrerequisites extends BaseStageHasPrerequisites
{
public function save(Doctrine_Connection $conn = null)
{
if( is_array( $this->getPrerequisiteId() ) )
{
foreach( $this->getPrerequisiteId() as $prerequisite_id )
{
$obj = new StageHasPrerequisites();
$obj->setPrerequisiteId( $prerequisite_id );
$obj->setStageId( $this->getStageId() );
$obj->save();
}
}
else
{
parent::save($conn);
}
}
(...)
}
So now if it encounters an array instead of a single value, it just creates a temporary object and saves it for each of this array's values.
Not an elegant solution, definitely, but it works (keep in mind that it is written for the specific structure of the data and it's just the effect of my methodology, namely See What's Wrong In The Debug Mode And Then Try To Correct It Any Way Possible).
I'm having an annoying problem. I'm trying to find out what fields of a form were changed, and then insert that into a table. I managed to var_dump in doUpdateObjectas shown in the following
public function doUpdateObject($values)
{
parent::doUpdateObject($values);
var_dump($this->getObject()->getModified(false));
var_dump($this->getObject()->getModified(true));
}
And it seems like $this->getObject()->getModified seems to work in giving me both before and after values by setting it to either true or false.
The problem that I'm facing right now is that, some how, sfWidgetFormSelect seems to be saving one of my fields as a string. before saving, that exact same field was an int. (I got this idea by var_dump both before and after).
Here is what the results on both var dumps showed:
array(1) {["annoying_field"]=> int(3)} array(1) {["annoying_field"]=>string(1)"3"}
This seems to cause doctrine to think that this is a modification and thus gives a false positive.
In my base form, I have
under $this->getWidgets()
'annoying_field' => new sfWidgetFormInputText(),
under $this->setValidators
'annoying_field' => new sfValidatorInteger(array('required' => false)),
and lastly in my configured Form.class.php I have reconfigured the file as such:
$this->widgetSchema['annoying_field'] = new sfWidgetFormSelect(array('choices' => $statuses));
statuses is an array containing values like {""a", "b", "c", "d"}
and I just want the index of the status to be stored in the database.
And also how can I insert the changes into another database table? let's say my Log table?
Any ideas and advice as to why this is happen is appreciated, I've been trying to figure it out and browsing google for various keywords with no avail.
Thanks!
Edit:
ok so I created another field, integer in my schema just for testing.
I created an entry, saved it, and edited it.
this time the same thing happened!
first if you what the status_id to be saved in the database, you should define your status array like this:
{1 => "a", 2 => "b", 3 => "c", 4 => "d"}
So that way he know that 1 should be rendered like "a" and so on. Then, when saving, only the index should be saved.
About saving in another database, my advise is to modify the doSave method defined by the Form class yo match your needs. I only know how Propel deals with it, maybe this could help:
the doSave method dose something like this:
protected function doSave($con = null)
{
if (null === $con)
{
$con = $this->getConnection();
}
$old = $this->getObject()->getModifiedValues($this);//Define this
$new_object = new Log($old);//Create a new log entry
$new_object->save($con));//save it!
$this->updateObject();
$this->getObject()->save($con);
// embedded forms
$this->saveEmbeddedForms($con);
}
Hope this helps!
Edit:
This is an example extracted from a model in one of my applications and its working ok:
Schema:
[...]
funding_source_id:
type: integer
required: true
[...]
Form:
$this->setWidget('funding_source_id', new sfWidgetFormChoice(array(
'choices' => array(1 => 'asdads', 2 => '123123123' , 3 => 'asd23qsdf'),
)));
$this->setValidator('funding_source_id', new sfValidatorChoice(array(
'choices' => array(1 => 'asdads', 2 => '123123123' , 3 => 'asd23qsdf'),
'required' => true
)));
About the log thing, that could be quite more complex, you should read the current implementation of the doSave method in the base form class, currently sfFomrObject on Symfony1.4., and when and how it delegates object dealing with modified values.
Okay,
It turns out I forgot to do a custom validator to use the array key instead.
