How do I get Entity to populate the values of foreign key objects at the controller action?
Do you have other properties being set via form fields in your view or are you simply passing the ID of the User back for some other reason. If you are updating other properties of your UserModel in the view then these should be serialized via model binding automatically as long as the naming convention is correct "i.e. ID="User.Id" or ID="User.FirstName"...

How do you populate an Entity with foreign keys from an Array in Symfony2/doctrine
When you use doctrine you shouldn't be working with foreign keys ( but with category objects. So in fact you should have converted the id to category outside your function. Another option is to add a new column called category which is of type integer and you set that directly so that you know have 2 class variables pointing to the same object but one has the relation the other just the id /** * @ManyToOne... */ protected $category; /** * @Column(type="integer") */ protected $categoryid; public function setCategory(PrefixMyBundleEntityCategory $category = null) { $this->category = $category; return $this; } public function getCategory() { return $this->category; } public function setCategoryId($categoryid = null) { $this->categoryid = $categoryid; ret

How can I use nested Json to populate Kendo UI grid?

IllegalArgumentException: Field xxx is a primitive class class xxx but marked as foreign
java.lang.IllegalArgumentException: Field FieldType:name=activity, class=Relation_Participants is a primitive class class com.lordcardrecorder.model.CardActivity but marked as foreign So for some reason ORMLite thinks that your Relation_Participants class is a primitive type. I suspect that the problem is invalid information inside of your Android ormlite_config.txt file which caches the field and type information. I would immediately remove this file and then re-run your program to see if it works. If it doesn't then you need to regenerate it. If the problem still happens then please post the section of the ormlite_config.txt file that lists the Relation_Participants fieldd. Is it saying it is a primitive?

populate class from ini using configparser
You should read the documentation for the configparser module, it does a decent job explaining things. Be sure to read the docs for the version of Python 3 you are using though, as the interface seems to have been extended quite a bit between versions. Starting in Python 3.2, it is possible to treat a ConfigParser instance as if it was a Python dictionary (the term used in the docs is the "mapping protocol"). That means, you can probably just create a class instance with FopsTest(**config), or perhaps FopsTest(**config["TheSectionICareAbout"]) if you only want the items from a specific section of the file. See this section of the docs for details.

Error when using in-class initialization of non-static data member and nested class constructor
Maybe this is the problem: §12.1 5. A default constructor that is defaulted and not defined as deleted is implicitly defined when it is odr- used (3.2) to create an object of its class type (1.8) or when it is explicitly defaulted after its first declaration So, the default constructor is generated when first looked up, but the lookup will fail because A is not completely defined and B inside A will therefore not be found.

how to declare a global friend function that takes an nested class of a template class?
For one thing, typename const Array<T>::Iterator is wrong. It should be const typename Array<T>::Iterator. Since typename is for helping the compiler know what to do with something after a ::, always put it immediately left of your A::B::C -type pattern. You can't name a specialization of a function template as a friend before the general template has been declared. And you can't declare that template until the type Array<T>::Iterator has been declared. One thing you could do: Make the entire function template a friend, not just the one specialization. template<class T> class Array { public: class Iterator { public: template <class U> friend typename Array<U>::Iterator operator+( const int, const typename Arr

How do I make a private nested class that can be used as a public field in the outer class?
If you really don't want to expose the inner type, you can to have the inner class implement an interface. Then, in the outer class, you expose X as being of the interface type but internally use the inner class' type. Personally, I would just make the inner class public. Users can't hurt anything by instantiating the class, so it's not a big deal to expose the constructor. Code for exposing the inner type, without exposing the constructor, via an interface: public class BoundingBox { public Vector3Double Positon { get; set; } public Vector3Double Apothem { get; set; } public IExtremasForX X { get { return _x; } } private ExtremasForX _x; public BoundingBox(Vector3Double position, Vector3Double size) { Positon = position; _x = new ExtremasForX(th

Why can't a static nested class access "this" pointer of outer class?
The difference between a static nested class and one that isn't static is precisely that an instance of a non-static inner class is associated with a specific instance of the enclosing class, while a static inner class isn't. There is no A.this for an instance of a static inner class to be associated with.

Trying to select by field from different class using foreign key, getting errors
The problem is that get_object_or_404(Notice, board__name=board_name) returns one Notice model instance and it's not iterable. One possible solution is to add this to a list and pass to the context: def board_lv(request, board_name): latest_notices = get_object_or_404(Notice, board__name=board_name) context = {'latest_notices': [latest_notices]} return render(request, 'noticeList.html', context) UPD for the next error: then, don't use get_object_or_404 if there could be more than one Notices per board. Use filter: def board_lv(request, board_name): latest_notices = Notice.objects.filter(board__name=board_name) context = {'latest_notices': latest_notices} return render(request, 'noticeList.html', context) Hope that helps.

Fluent API for having multiple foreign keys from same class
Either use the fluent API or data annotations in your entity class. If using data annotations then mark your collection as [ForeignKey("CasteID")] for example. To use the fluent API you would need to specify it in your DBContext by overriding OnModelCreating such as: protected override void OnModelCreating(DbModelBuilder modelBuilder) { } See Configuring relationships with Fluent API You could omit both approaches by using convention. It requires that your foreign key has the same name + Id as your related class - such as Caste, CasteId. The relationship is then inferred by EF. Here's a link which describes EF conventions more fully: Entity Framework Conventions

How to populate a Tree View with class variables (Windows Forms)
For this kind of behavior in Windows Forms, I'd recommend that you use the PropertyGrid control: (Source: Getting the Most Out of the .NET Framework PropertyGrid Control) All you need to do is set the SelectedObject property to your custom object and the PropertyGrid will automatically discover your class' properties. It also supports hierarchical objects and editing. Some types, such as Colors, have built-in editors (as depicted above). The TreeView is not well suited for this kind of automatic binding... though you could write your own code to perform the binding for you using reflection. I've not tried myself, but I beleive that the PropertyGrid's support for Drag'n'Drop is lacking, as evidenced by this post: C# PropertyGrid drag drop

Foreign key creation in one-to-one table-per-concrete-class structure
We use standard JPA (no hibernate-specific hacks) and had the same problem, and we did not find a nice solution. Assumptions: AbstractProperty is a class in a package that is reusable/shared in different applications, and that you don't want a reference to an application specific Owner Class. ConcreteProperty & AnotherProperty is application specific. In this case, the solution would be to put references in ConcreteProperty to the Owner (with foreign keys), eventually both with AnotherProperty extending the same ApplicationProperty, and making the abstractPropertyId private, so that on setting the Owner, it is set automatically.

Nested class in for loop, will there be n instances of the class?
Having a class definition inside a method is just syntax: it's still a perfectly normal class definition. For the Inner objects (new Inner()) you create, that means: each object will be eligible for garbage collection just like any other object, immediately after the loop iteration yes, the object will eventually be garbage collected the object will linger until it is garbage collected, but won't be accessible from other places (since no reference to it leaked). For the class itself, this means: the class will be loaded as usual (only once) the class will not be re-loaded on each iteration the class will not even be re-loaded on a second invocation of test the class can be GCed according to the normal rules of GCing classes (which are pretty stringent)

How do I use BeanUtils.populate to populate a bean from a form which has a checkbox
Just a guess - the value of your flag is "Enabled", try something like "true", "on" or "1". Or do you have mapping code that maps "Enabled" to true? Also, there seems to be a problem when the checkbox is unchecked, as in that case, nothing is sent to the server - there seems to be a common solution in using Javascript to set a hidden field to a value "on" or "off" and considering the hidden field only, and ignoring the checkbox itself.

The best you could do is for each of the results of the above query, run the query again, substituting the TABLE_SCHEMA and TABLE_NAME as the string constants in the WHERE clause (be careful not to enter into infinite loops if you have circular foreign keys).

Error Code: 1215. Cannot add foreign key constraint (foreign keys)
The most likely issue is this line: FOREIGN KEY (classLeader) REFERENCES student(studentID), The datatype of classLeader is VARCHAR(255). That has to match the datatype of the referenced column... student.studentID. And of course, the student table has to exist, and the studentID column has to exist, and the studentID column should be the PRIMARY KEY of the student table (although I believe MySQL allows this to be a UNIQUE KEY, rather than a PRIMARY KEY, or even just have an index on it.) In any case, what's missing here is the output from SHOW CREATE TABLE student; There's a datatype mismatch. The classLeader VARCHAR(255) column cannot be a foreign key reference to studentID INT. The datatypes of the two columns has to match.

Nested class written outside of the class
The closest you can get to this type of encapsulation is using a partial parent class: internal partial class Parent { private Child1 c1Instance = new Child1(); private Child2 c2Instance = new Child2(); } internal partial class Parent { private class Child1 { } } internal partial class Parent { private class Child2 { } } You can split these up into multiple files, the end result will be the same - Child1 and Child2 will be private classes internal to Parent and inaccessible elsewhere. Makes it a bit more confusing sometimes, but I think it's the closest thing to what you are trying to achieve.

Please remember that depending on your transaction isolation level (1) the changes are not propagated to the DB before you successfully committed the transaction. And (2) the new state of the DB is not visible until you start a new transaction. And even so, as far as I know, MySQL does not guarantee any "propagation delay". And I don't think there is any mechanism available in MySQL to signal other connections than a transaction has successfully committed and that changes are now visible.
