I nedd to know if there is a way to persist data in Driver Method
Display(MyPart part, string displayType, dynamic shapeHelper)
Inside the method, I need to do something like:
var item = _contentManager.Get(part.Id);
item.As<MyPart>().Property = 10;
and then, update model data with some method like _contentManager.UpdateEditor() or TryUpdateModel()
Is there a way to do that?

Let's assume I have an ActionDescriptor (or MethodInfo) object that points to some action method in my application. I want to get route table's entries (System.Web.Routing.Route objects) associated with this action.
Is there, by any chance, some framework method that might get me this information, or do I have to parse the route table somehow? How would you suggest to do this, in the second case?
That's how I did this:
var routeProvider = new DefaultDirectRouteProvider();
var routeEntries = routeProvider.GetDirectRoutes(
_actionDescriptor.ControllerDescriptor, new[] { _actionDescriptor }, new DefaultInlineConstraintResolver());
i have create an sql function in my database that take to Date params and get data from 5 tables.
after that add it to project as entity framework from database and the code generated is:
[DbFunction("Dr_EmploEntities", "SelectEmployee")]
public virtual IQueryable SelectEmployee(Nullable frm_date, Nullable to_date)
{
var frm_dateParameter = frm_date.HasValue ?
new ObjectParameter("frm_date", frm_date) :
new ObjectParameter("frm_date", typeof(DateTime));
var to_dateParameter = to_date.HasValue ?
new ObjectParameter("to_date", to_date) :
new ObjectParameter("to_date", typeof(DateTime));
return ((IObjectContextAdapter)this).ObjectContext.CreateQuery("[Dr_EmploEntities].[SelectEmployee](#frm_date, #to_date)", frm_dateParameter, to_dateParameter);
}
public DbSet SelectEmployee_Result { get; set; }
as you see i have now "SelectEmployee_Result" that don't take any params, and "SelectEmployee" that take two date params.
after that i have create an controller for "SelectEmployee_Result" class.
after that i run my project Index View that working with "SelectEmployee_Result" class give me err:
"The type 'SelectEmployee_Result' is mapped as a complex type. The Set method, DbSet objects, and DbEntityEntry objects can only be used with entity types, not complex types."
and i make breakpoint and see that "SelectEmployee_Result" has no data so i change the Index Code in controller and fill "SelectEmployee" with two date params
and when run got same err msg too.
so how can i fill "SelectEmployee_Result" from the beginning with data between two dates to let me use it in all views ?
all what i need here is view data i got i edit before saving it in database Like using DataTable but i need to do that from Entity with sql function
and what is difference between "SelectEmployee" that is my function name and that is need two params and "SelectEmployee_Result"?
I have written a helper function (I'm quite proud of this it - look what I can do!) that does what I need. Is there a built in way, though, to access a ContentItem's fields without having first to get the "main" ContentPart? The word "main" here means the ContentPart with the same name as the ContentType.
#functions
{
dynamic GetMainPartFromContentItem(ContentItem item)
{
var contentType = item.TypeDefinition.Name;
var parts = item.Parts as List<Orchard.ContentManagement.ContentPart>;
dynamic mainPart = parts.First(p => p.PartDefinition.Name.Equals(contentType));
return mainPart;
}
}
dynamic mainPart = GetMainPartFromContentItem(contentItem);
var shortTitle = mainPart.ShortTitle.Value; // access an InputField's value
If you have a ContentType called Page with a field called Topic you can do:
dynamic item = Model.ContentItem;
string topic = item.Page.Topic.Value;
Basically when you add fields directly to the content item, they are being added to a part on your content item called whatever your content type is, in this case Page
In the Youtube API, there is the power to request a "partial feed".
This allows the app developer to tailor the size and sturcture of the data returned, by specifying which "fields" to return.
i.e. GET api/person/1?fields=(id,email) would return a DTO containing only the id and the email fields, not the whole person response.
How would you attempt this using ServiceStack? Is there some way to attach a callback to the serialiser to control which properties to include in the response object?
From my experience servicestack only returns fields that actually has data. If my experience is correct then all you would need to do is figure out the best way to architect the request so that it is asking for specific data to return, this way you would only populate the response with data requested thus servicestack would only return that.
I implemented this for an API that only returns JSON.
First I created two structs to (de)serialize and interpret the "fields" query argument recursive syntax:
FieldSelector, which specifies a field and possibly its children FieldSelection enclosed between parenthesis;
FieldsSelection, which is a comma-separated list of FieldSelector.
I've used structs instead of classes because, AFAIK, you can't override class (de)serialization from/to URLs in ServiceStack. With structs you can do it by overriding ToString (serializer) and providing a constructor accepting a string as parameter (deserializer).
Then you include this on every request DTO that returns JSON:
FieldsSelection Fields { get; set; }
On a custom ServiceRunner<T>.OnAfterExecute you serialize the response DTO to JSON, parse it with ServiceStack.Text's JsonObject and apply the fields selection recursively with a method like this:
private static JsonObject Apply(this JsonObject json, FieldsSelection fieldMask)
{
IEnumerable<string> keysToRemove = json.Keys.ToList().Except(fieldMask.Keys);
foreach (var key in keysToRemove)
json.Remove(key);
foreach (var selector in fieldMask.Selectors.Values.Where(s => s.HasSubFieldsSelection))
{
var field = json[selector.Field];
if (field == null)
continue;
switch (field[0])
{
case '{':
json[selector.Field] = Apply(json.Object(selector.Field), selector.SubFieldsSelection).ToJson();
break;
case '[':
var itensArray = json.ArrayObjects(selector.Field);
for (int i = 0; i < itensArray.Count; i++)
itensArray[i] = Apply(itensArray[i], selector.SubFieldsSelection);
json[selector.Field] = itensArray.ToJson();
break;
default:
throw new ArgumentException("Selection incompatible with object structure");
}
}
return json;
}
Then you return the result as your response DTO. I've also implemented negative fields selectors (fields=-foo selects all DTO fields except foo), but you get the idea.
Look at ServiceStack.Text.JsConfig properties, they have all the hooks and customizations ServiceStack's text serializers support. Specifically the hooks that allow you to custom deserialization are:
JsConfig<T>.DeserializeFn
JsConfig<T>.RawDeSerializeFn
JsConfig<T>.OnDeserializedFn
We were able to implement said filtering by adding custom service runner and using some reflection in it to construct ExpandoObject with required field set by response DTO. See this for more info on service runners.
UPDATE: As it turns out, i had a leftover this.model = new MasterModel(); in my subViews initialize() function.
I am trying to separate my huge view to smaller views and so I have created a "master" layout view that attaches to itself some subviews and passes it's model to them.
However, it seems that when my sub-view updates the model, these changes are not reflected on the "master" view's model.
Here's what I am trying to do:
var master = new MasterModel();
var masterView = new MasterView({model:master});
Inside of the masterView initialize() function I do this:
function: initialize() {
this.subView = new subView({model:this.model});
}
And the code that changes the model in subView is this:
function: setCurrency() {
this.model.set({ currency: this.$('.currency').val() });
}
Maybe I am doing something completely wrong here?
How many things have class "currency" are on your page?
I don't think this.$('.currency').val() means what you think it means. I think you're wanting something like $(this.el).find('.currency').val() (are you using 0.9.1? then you could shorten that to $el.find('.currency').val() ). What you have will always grab the first item on the page with class "currency". this.$ is just a convenience reference to what would normally be the global Zepto or jQuery object. Hence, my question.
Edit: awaiting response to clarification question.
Make your model global so instead of:
var master = new MasterModel();
use
window.master = new MasterModel();
and then pas this to your subViews
function: initialize() {
this.subView = new subView({model:window.master});
}
