For the first time i am trying to use spring-data.
Everything works fine when i'm using object that has simple objects.
Now i'm trying to add Location object to User class.
User creation works fine (i use POST request to /users).
But when i try to add location (using PUT or PATCH to /users/1/locations) then comes 201 CREATED status, but no location is added (checked with GET /users/1/locations).
Source code is very simple and is accesible under this link.
Thanks for help in advance
Have you tried annotating your Location class with #Embeddable and your location variable inside the User class with #Embedded? You need to do this in order to force an object to be stored inside of another in the database.

In glade it is possible to set an unique ID to an object. In the code one can obtain a pointer to this object by searching for it's "glade ID" via gtk_builder_get_object().
However for my current use-case I just want to read out this ID from an GObject. What's the API to do so ?
You can't. The builder ID is stored in the builder internally, not in the GObject.
The reason for this is that IDs must be unique per builder, which would be impossible to enforce if you were able to get and set them via some GObject API.
You could use gtk_widget_get_name() to identify an object.
It is possible using Gtk.Buildable.get_name(object). This method will return the Glade object id.
This snippet will print all object ids in your Glade XML:
builder = Gtk.Builder()
builder.add_from_file("my-window.glade"))
for obj in builder.get_objects():
print(Gtk.Buildable.get_name(obj))
As stated by #ptomato it's seems not possible.
I found that in that line in the documentation:
All the fields in the GObject structure are private to the
implementation and should never be accessed directly.
But you can circumvent it because at one point in your code you were refering to it by the id that you typed in (or the code you wrote type in) so you just need to store it at that point. And link it somehow (with a variable or a data structure) to the name of the variable holding the object.
I have splitted my application into two main areas.
Part(A)
PartStashContainer(B)
The content of A should be set based on what user wants.
So basically i can have 1..N classes which could be used in Class URI of Part in application model.
I don't know if i should replace the whole Part(A) with new dynamically created Part(C) which has content i want, or i should somehow to modify the existing Part (call setContributionURI, or setObject methods on Part object?).
It does make more sense to me to modify the existing Part, because it is defined in Application model and therefore already describing the location where the content should be.
Possible solutions:
Modify the Part object so it "reload" its content based on new setup (But how? Can setContributionURI or setObject methods help?)
Remove the old Part and add dynamically on same place in Application model the new Part (using EModelService and EPartService).
other solution??
If you want to reuse the Part then do something like:
MPart part = find or inject your part
MyClass myClass = (MyClass)part.getObject();
... call a method of MyClass to change the contents
MyClass is the class you specify for the object in the application model. You should add a method to that to let you change the contents.
Don't try to call setObject, this is really only for use by Eclipse. I don't think setContributionURI would do anything after the part is created (but I am not sure).
If you want to use different classes for the different data then you really should use different Parts.
I have the current scenario:
I'm using EF6 Code first, and have created a data-model something like this:
public class MainObject{
..some properties
IList<SubObject> SubObjects{get;set;}
}
public class SubObject{
..some properties
IList<SubSubObject> SubSubObjects{get;set;}
}
public class SubObject{
..some properties
IList<SubObject> SubObjects{get;set;}
}
So basically I have a main object, that has 0 to many subobjects, and there is a many to many relationship between the subobject and the subsubobjects.
I am creating a MVC application, so my normal program flow is that the user request a page that basically uses a MainObject as it's data model. Then the user interacts with the page and changes, adds or removes subobjects and subsubobjects as he wishes, and then clicks save. On save, the objectgraph is sent back to the controller and it looks correct according to the changes done by the user on the client side. Now my problem is the following:
How to store this back into the database in a good fashion.
I need to attach my object back into the context, but I have no clue which objects are new, modified or deleted.
I have written some code that partially works now, but it's getting so ugly that I really don't want to go down that path. Would it be possible somehow to fetch the relevant object graph from the database, and have EF compare the two graphs toward eachother, and then save the relevant changes to the database?
Any help to make this smoother would be greatly appreciated.
I ended up using GraphDiff to solve this for me, and it works just great! This really should be built into EF, but untill it does, this is a great substitute.
To solve the example given in my question above, this will make sure that the detached graph gets saved properly (given I have a MainObject I want to save called main):
context.UpdateGraph(main, map =>map
.AssociatedCollection( m => m.SubObjects, with => with
.AssociatedCollection( s => s.SubSubObjects)
)
);
context.SaveChanges();
I am building a JavaScript app, and have been learning JavaScript and Backbone, and have added Backbone-relational to it. It saves to a Django-tastypie REST server.
So before I was using Backbone-relational, I would create a new object, and either set the attributes when it was created, by passing them to the constructor, or passing a dictionary of attributes to the save() method.
e.g in CoffeeScript:
myModel.save {attribute:value , foreignKey_attribute : '/api/resourceUri/'}
success ->
....
Now I have switched to Backbone-relational, it solves a lot of problems fetching the data, but I cant seem to set the foreign key attribute as before.
Either passing the dictionary to the constructor, or the save method. When I look at the object in the console, or the contents of the POST, the foreign_key attribute is always null.
Is there a way around this, or another way of setting the foreign_key_attribute (given that I have the foreign key id)?
Ok, worked it out.
Rather than trying to set the flowcell to a resource_uri string, set it as the flowcell object.
Then in the relations I needed to set the following:
includeInJSON: 'resource_uri'
This serialzes the object the way the tastypie back end expects it.
Hi I have a situation where I need to look up the number of recently viewed products on catalog/product/view.phtml. In the recently viewed 'product_viewed.phtml' file it calls
$_products = $this->getRecentlyViewedProducts()
to get the recently viewed. How would I access this method from within the catalog/product/view.phtml file?
I don't know where this method is. I've tried searching for it but it doesn't seem to exist. When I write click it in Netbeans and click go to declaration it takes me to
class Mage_Reports_Block_Product_Viewed extends Mage_Reports_Block_Product_Abstract
Actually on the class itself. This class only has _toHtml(), getCount(), and getPageSize() methods.
I just need to know whether there are any recently viewed products.
Any help most appreciated!

If you look into 'Mage_Reports_Block_Product_Viewed', you will notice:
$this->setRecentlyViewedProducts($this->getItemsCollection());
That 'getItemsCollection' method is defined in the abstract class... And you will notice this abstract class will create a model based on $_indexName defined in the (subclassed) block.
If you just want the collection, you can probably get away with:
$_products = Mage::getModel('reports/product_index_viewed')->getCollection();
And then adding whatever you want to the collection:
$_products
->addAttributeToSelect('*')
->setAddedAtOrder();
// optionally add other methods similar to Mage_Reports_Block_Product_Abstract::getItemsCollection
Another approach that might be more suited would be to create the original block:
$productViewedBlock = $this->getLayout()->createBlock('reports/product_viewed');
On which you can simply call whatever you want:
$_collection = $productViewedBlock->getItemsCollection();
$_count = $productViewedBlock->getCount();
The getRecentlyViewedProducts function is a magical getter that gets the data that was set with setRecentlyViewedProducts in app/code/core/Mage/Reports/Block/Product/Viewed.php (which builds it using app/code/core/Mage/Reports/Block/Product/Abstract.php's function _getRecentProductsCollection).
This is complicated stuff that you don't want to reproduce; its better, IMO to make your own Block that extends Mage_Catalog_Block_Product_Abstract that will give you access to the same functionality, and drop your new block into the page you're working on.
