How to update a Model by ORM in Phalcon without updating its null properties?
I have tried with update or save function but it results the row with null value
Update:
I've tried with Class:
class Company extends Model {
public $id; // Primary key
public $name;
public $brand;
public function initialize()
{
$this->useDynamicUpdate(true);
}
public function getSource()
{
return 'company';
}
}
then I updated by:
$company = new Company();
$company->id = 15;
$company->name = 'New Company';
$company->update();
Final field brand on effected row goes NULL
I'm using Phalcon 2.0.6
result dependency of table type ....
try this:
$company = new Company();
$company->id = 15;
$company->name = 'New Company';
$company->update();
$company->refresh();
or use
afterFetch()

I am facing the problem whereby I don't know the syntax of letting the id of my property model equals to property_id value in property_doc table.
In PropertyDoc model
public function property()
{
return $this->belongsTo(Properties::class, 'property_id');
}
In Properties model
public function property_id()
{
return $this->hasMany(PropertyDoc::class, 'property_id');
}
In PropertyController
public function StoreInfoProperty(Request $request)
{
$propertyInfo = new PropertyDoc;
$propertyInfo->property_id = $property_id;
}
I am stuck at retrieving the default id value in properties database to be equal to the property_id in property_docs database. Thank you.
You should change the naming of the relationship, see my example below:
In Properties model
public function propertyDocs()
{
return $this->hasMany(PropertyDoc::class, 'property_id', 'id');
}
In PropertyDoc model
public function property()
{
return $this->belongsTo(Properties::class, 'property_id', 'id');
}
In controller
public function StoreInfoProperty(Request $request)
{
$propertyDoc = PropertyDoc::with(['property'])->where('...logic here');
$property_id = $propertyDoc->property->id;
}
hope can help you and happy coding !
I try to use foreign collections in ORMLite. However, I dont know how to convert it into list. I try to do something like this :
public class Car implements Serializable {
#DatabaseField(columnName = "carId" , generatedId = true, id=true)
private int id;
#DatabaseField(columnName = "carNumber")
private String mNumber;
#DatabaseField(columnName = "carName")
private String mName;
#ForeignCollectionField(eager = true,columnName = "carParts")
private Collection<Part> mParts;
ArrayList<Part> parts = new ArrayList<>(mParts);
public ArrayList<Part> getParts() {
return parts;
}
public void setParts(ArrayList<Part> parts) {
this.parts = parts;
}
but when I try to use it I get exception :
java.lang.NullPointerException: collection == null
at this line :
ArrayList<Part> parts = new ArrayList<>(mParts);
please, help.
The reason is simple - you have to wait until mParts will be initialized by ORMLite library, then you can create ArrayList from it.
public ArrayList<Part> getParts() {
return new ArrayList<>( mParts );
}
i want to get some data from a mobile app using POST and save it on my laravel 5 application database.
mycontroller
public function postBookingDetails(Request $request)
{
$FodMaps = $request->only('name','fructose');
return $FodMaps;
}
Route::post('booking', 'FodMapController#postBookingDetails');
table Structre:
id (autoincrement)
name varchar
fructose varchar
Model
protected $table = 'food_directory';
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = ['name', 'lactose', 'fructose','polyols','fructan'];
public function postBookingDetails(Request $request)
{
$FodMaps = $request->only('name','fructose');
$FoodDirectory = new FoodDirectory;
$FoodDirectory->name = $request->input('name');
$FoodDirectory->fructose = $request->input('fructose');
$FoodDirectory->save();
return $FoodDirectory;
}
also add to your model:
public $timestamps = false;
And ofcourse dont forget to add to the top of your controller:
use App\FoodDirectory;
All of my entities (that are mapped to a database table) inherit from an entity class with a dynamic component on it called Attributes e.g.:
public abstract class Entity<T> {
public virtual T Id { get; set; }
private IDictionary _attributes;
public virtual IDictionary Attributes {
get { return _attributes ?? (_attributes = new Hashtable()); }
set { _attributes = value; }
}
}
The Attributes collection allows me to add extra fields to each entity without directly changing the entity itself. This allows me to make my application more modular.
For example say I have the following entity:
public class User : Entity<int> {
public virtual string Name { get; set; }
}
Now say I have a Forum module which needs a NumPosts property against the User. I would add the field against the Users table in the database. This field is non nullable and has a default value of 0. I then map the field using the dynamic component against the User entity.
However when I try inserting the user by saying:
session.Save(new User() { Name = "Test" });
It throws an error as it's expecting me to set a value for NumPosts and the generated SQL would be something like:
INSERT INTO Users (Name, NumPosts) VALUES ('Test', NULL)
However NumPosts does not allow nulls and hence the error. Ideally I'd like it to say the following if the Attributes collection does not contain an entry for NumPosts:
INSERT INTO Users (Name) VALUES ('Test')
An alternative is to say the following which would work fine:
session.Save(new User() { Name = "Test", Attributes = new Hashtable() { { "NumPosts", 0 } } });
The problem I have is that I don't want the modules to have a dependency on each other and I can't really say this.
For reference here's a bare bones version of session factory method which maps the NumPosts field:
return Fluently.Configure()
...
.ExposeConfiguration(c => {
// Get the persistent class
var persistentClass = c.GetClassMapping("User");
// Create the attributes component
var component = new Component(persistentClass);
// Create a simple value
var simpleValue = new SimpleValue(persistentClass.Table);
// Set the type name
simpleValue.TypeName = "Int32";
// Create a new db column specification
var column = new Column("NumPosts");
column.Value = simpleValue;
column.Length = 10;
column.IsNullable = false;
column.DefaultValue = "0";
// Add the column to the value
simpleValue.AddColumn(column);
// Ad the value to the component
component.AddProperty(new Property() { Name = column.Name, Value = simpleValue });
// Add the component property
persistentClass.AddProperty(new Property() { Name = "Attributes", Value = component });
})
.BuildConfiguration();
I'd appreciate if someone could let me know if this is possible. Thanks
You know how to make it working as described above:
... An alternative is to say the following which would work fine:
session.Save(new User()
{
Name = "Test", Attributes = new Hashtable() { { "NumPosts", 0 } }
});
... The problem I have is that I don't want the modules to have a dependency on each other and I can't really say this...
In case, that the biggest issue is the explicit Attributes initialization ("...I don't want the modules to have a dependency...") we can use:
12.2. Event system
So, with Listener like this:
[Serializable]
public class MyPersistListener : NHibernate.Event.ISaveOrUpdateEventListener
{
public void OnSaveOrUpdate(SaveOrUpdateEvent #event)
{
var entity = #event.Entity as Entity<int>; // some interface IHaveAttributes
if (entity == null) // would be more appropriate
{
return;
}
var numPosts = entity.Attributes["NumPosts"] as int?;
if (numPosts.HasValue)
{
return;
}
entity.Attributes["NumPosts"] = 0;
}
}
Based on this doc snippet:
Configuration cfg = new Configuration();
ILoadEventListener[] stack = new ILoadEventListener[] { new MyLoadListener(), new DefaultLoadEventListener() };
cfg.EventListeners.LoadEventListeners = stack;
This should be the init in our case:
.ExposeConfiguration(c => {
var stack = new ISaveOrUpdateEventListener [] { new MyPersistListener() };
c.EventListeners.SaveEventListeners= stack;
I am new on Yii framework, so please i need some help where to start.
What i need is, action and module to display a form to a user, which his will be able to edit is own profile (with profile picture), so i have 3 table
user_account || user_personal || user_general
how can i build a form that insert and update those 3 table at once?
i try this:
This is what i did, but its still not saving the data even into 1 table.
public function actionUpdate() {
$model = new ProfileUpdate();
if(isset($_POST['ProfileUpdate']))
{
$model->attributes = $_POST['ProfileUpdate'];
if($model->validate())
{
$account = new Profile();
$account->userid = Yii::app()->user->id;
$account->name = $model->name;
$account->website = $model->website;
$account->category = $model->category;
$account->save();
$this->redirect('profile');
}
}
model:
class Profile extends CActiveRecord
{
public $userid;
public $name;
public $website;
public $category;
public static function model()
{
return parent::model(__CLASS__);
}
public function tableName()
{
return 'userinfo';
}
public function primaryKey()
{
return 'id';
}
public static function userExists($user)
{
return self::model()->countByAttributes( array('username'=>$user) ) > 0;
}
}
You can use all three models in a single function
for example:
In create function
$model_account = new user_account;
$model_personal= new user_personal;
$model_general = new user_general;
$this->render('create',array(
'model_account'=>$model_account, 'model_personal' => $model_personal, 'model_general' => $model_general
));
here the all three models pass by render to create page.
in form page you can use the every model attributes as fields
Like this
echo $form->textField($model_account,'account_name');
echo $form->textField($model_personal,'email');
echo $form->textField($model_general,'address');
In create function / Update function
$model_account->attributes = $_POST['user_account'];
$model_personal->attributes = $_POST['user_personal'];
$model_general->attributes = $_POST['user_general'];
if($model_account->validate() && $model_personal->validate() && $model_general->validate())
{
$model_account->save();
$model_personal->save();
$model_general->save();
}
