How can I match with the persistent_object_identifier? - flow-framework

Is there a way to use the query interface and limit the repository query by the persistent object identifier? Like ...
// $addTaskIds is an array with identifiers as strings
$query = $this->createQuery();
$query->matching(
$query->logicalOr(
$query->like('title', '%'.$searchstring.'%'),
$query->like('description', '%'.$searchstring.'%'),
$query->in('persistent_object_identifier', $addTaskIds)
)
);
return $query->execute();
I've tried the code above and it doesn't work. Did I forgot something? Does the query builder offer that anyway? Do I have to switch on a yaml setting?

The idea was good. But the table row persistent_object_identifier doesn't belong to the object itself. You can however use Persistence_Object_Identifier.
For that you need the identifiers as strings not as whole objects. And make sure that the second parameter of 'query in' is an array not a single string.

Complicated where request in Rails

I have two tables in my rails app: properties and requests. Both tables have field called address. But in property address is always single value like Hollywood for example and in request table there could be complicated string like ["Hollywood", "Beverley Hills"]. My task is to get all properties which match by address. It means that if we have in request ["Hollywood", "Beverley Hills"] i need all properties that have address as Hollywood and all Beverley Hills. I tried something like this:
#properties = Property.where("address = ? ", #request.address)
and:
#properties = Property.where("address IN (?) ", #request.address)
but both variants don't work and i think because #request.address is actually string, not array.
So i would like if somebody would suggest me some good solution.
Your first try is wrong, as address in Property is a single value.
Your second try is correct but not the best.
You can use Property.where(address: #request.address). But you have to be sure that #request.address is an Array of String.
You shouldn't save an Array as a String like that: "[\"Hollywood\", \"Beverley Hills\"]. It is too hard to parse in the application. If you want to save this way, you will be better using serialize :address, Array in the model, because then it will return an Array when you try to access the attribute.
Anyway, check if #request.address in an Array of String, if not, parse it to be an Array of String.
You can just wrap it in an array
#properties = Property.where(address: [#request.address])

Phalcon Save: Can I update only specified columns if update?

I have a table with this columns:
param_id
val_value
val_flag
date_value
tmp_value
tmp_flag
And I have an array of elements, I always have param_id and date_value, but sometimes i have val columns and other times I have tmp columns.
I use $data->save() because sometimes I need to create a new register in db and other times I need to update the register with param_id and date_value.
The question is: Is there any way to do an insert/update but when is an update, only update tmp columns or val columns? I think a find First is my only option, but maybe there is another way.
Thank you.
[EDIT]
I'm trying with the whitelist but it does not work. Let me explain how the method works: I get a request to a web service, process the xml and generate an array of elements with the information collected, after processing these elements I have an array of elements of the class appropriate to save, but these may be new or existing and may contain tmp or val values, I have tried with this but I still change the values to null.
if ($medida->tipo == 'temporal'){
$whiteList = array('val_value','val_flag');
}else if ($medida->tipo == 'validado'){
$whiteList = array('tmp_value','tmp_flag');
}
$dato->save(null, $whitelist);
I do not have data of the post, I use null instead, I have also tried to use an array with the manual assignment of the data obtaining the same result.
Here are two options that can help you:
1) Use 'whitelist' for the save() method.
$obj->save($this->request->getPost(), ['tmp_1', 'tmp_2']);
More info in the documentation.
2) Use the 'Event Manager'.
The methods beforeCreate() and beforeUpdate() will be useful so you can decide which fields to use.
More info in the documentation.
Also if you really want phalcon phql to update only columns which changed you need to enable dynamic update.

Odata Url conversion with descending orderby

i need to get data by descending orderby Visidate of patient so i tried url like this
192.168.1.105:33396/FalconCPDataService.svc/DEPhysicians?$format=json&$expand=DEPatientVisits&$orderby=DEPatientVisits/VisitDate+desc
but showing exception
{"odata.error":{"code":"","message":{"lang":"en-US","value":"The parent value for a property access of a property 'VisitDate' is not a single value. Property access can only be applied to a single value."}}}
The reason is that DEPatientVisits is not a single valued navigation property, so it is unable to append a property name to it. If it is a single valued, it works fine, such as:
http://services.odata.org/v4/OData/OData.svc/Products?$expand=Supplier&$orderby=Supplier/Name
Thanks for inviting.
I am not fully understand your question. you want to sort entities in DEPhysicians? or DEPatientVisits?
If you are try to get DEPhysicians inline expand DEPatientVisits, and want sort entities in DEPatientVisits by VisitDate, you can try:
locolhost/FalconCPDataService.svc/DEPhysicians?$format=json&$expand=DEPatientVisits($orderby=VisitDate desc)
If you are try to sort entities in DEPhysicians according to DEPatientVisits\VisitDate, then, just as the answer from #tanjinfu, DEPatientVisits should not be a collection. Otherwise, which VisitDate of entry in DEPatientVisits you want to used to sort?

How can i write a query that returns all objects except a given one?

im trying to write a simple query that would be easy if i had access to the persistence_object_identifier. I kickstarted my models and so i dont have them.
What i want to do is:
function getAllExcept($obj){
$query = $this->createQuery();
$query->matching(
$query->logicalNot(
$query->equals('persistence_object_identifier', $obj)
)
);
return $query->execute();
}
I tried a lot but i cannot make it work.
I could easily call ->toArray() and filter the one object out, but the fluid pagination widget needs the QueryResultInterface...
The property's name is Persistence_Object_Identifier (mind the case). It is injected by AOP in https://git.typo3.org/Packages/TYPO3.Flow.git/blob/HEAD:/Classes/TYPO3/Flow/Persistence/Aspect/PersistenceMagicAspect.php#l58.
replace
$query->equals('persistence_object_identifier', $obj);
with
$query->equals('Persistence_Object_Identifier', $obj);
It will work.

Hydrating Database

I am new to learning and understanding how Hydration works, just wanted to point that out first. I'm currently able to Hydrate Select and Insert queries without any problems.
I am currently stuck on trying to Hydrate Update queries now. In my entity I have setup the get/set options for each type of column in my database. I've found that the ObjectProperty() Hydrator works best for my situation too.
However whenever I try to update only a set number of columns and extract via the hydrator I am getting errors because all the other options are not set and are returning null values. I do not need to update everything for a particular row, just a few columns.
For example in my DB Table I may have:
name
phone_number
email_address
But I only need to update the phone_number.
$entity_passport = $this->getEntityPassport();
$entity_passport->setPrimaryPhone('5551239876');
$this->getTablePassport()->update($this->getHydrator()->extract($entity_passport), array(
'employeeid' => '1'
));
This returns an error because setName() and setEmailAddress() are not included in this update and the query returns that the values cannot be null. But clearly when you look at the DB Table, there is data already there. The data that is there does not need to be changed either, only in this example does the PrimaryPhone() number.
I've been looking and reading documentation all over the place but I cannot find anything that would explain what I am doing wrong. I should note that I am only using Zend\Db (Not Doctrine).
I'm assuming I've missed something someplace due to my lack of knowledge with this new feature I'm trying to understand.
Perhaps you don't Hydrate Update queries... I'm sort of lost / confused. Any help would be appreciated. Thank you!
I think you're having a fundamental misconception of hydration. A hydrator simply populates an entity object from data (hydrate) and extracts data from an entity object (extract). So there are no separate hydrators for different types of queries.
In your update example you should first retrieve the complete entity object ($entity_passport) and then pass it to the TableGateway's update method. You would retrieve the entity by employeeid, since that's the condition you're using to update. So something like this:
$entity_passport = $passportMapper->findByEmployeeId(1);
$entity_passport->setPrimaryPhone('5551239876');
$this->getTablePassport()->update($this->getHydrator()->extract($entity_passport), array(
'employeeid' => $entity_passport->getId()
));
This is assuming you have some sort of mapper layer. Otherwise you could use your passport TableGateway (I assume that's what getTablePassport() returns, no?).
Otherwise, if you think retrieving the object is too much overhead and you just want to run the query you could use just a \Zend\Db\Sql\Sql object, ie:
$sql = new \Zend\Db\Sql\Sql($dbAdapter);
$update = $sql->update('passport')
->set(array('primary_phone' => $entity_passport->getPrimaryPhone()))
->where(array('employeeid' => $employeeId));
Edit:
Maybe it was a mistake to bring up the mapper, because it may cause more confusion. You could simply use your TableGateway to retrieve the entity object and then hydrate the returned row:
$rows = $this->getTablePassport()->select(array('employeeid' => 1));
$entity_passport = $this->getHydrator($rows->current());
[...]
Edit 2:
I checked your gist and I noticed a few things, so here we go:
I see that your getTablePassport indeed does return an object which is a subclass of TableGateway. You have already set up this class for it to use a HydratingResultset. This means you don't need to do any manual hydrating when retrieving objects using the gateway.
You also already implemented a Search method in that same class, so why not just use that? However I would change that method, because right now you're using LIKE for every single column. Not only is it very inefficient, but it will also give you wrong results, for example on the id column.
If you were to fix that method then you can simply call it in the Service object:
$this->getTablePassport->Search(array('employeeid' => 1));
Otherwise you could just implement a separate method in that tablegateway class, such as
public function findByEmployeeId($employeeId)
{
return $tableGateway->select(array('employeeid' => $employeeId));
}
This should already return an array of entities (or one in this specific case). P.S. make sure to debug and check what is actually being returned when you retrieve the entity. So print_r the entity you get back from the PassportTable before trying the update. You first have to make sure the retrieval code works well.
