How do I get an attribute using the 'amazon-ecs' gem?

How do I get an attribute using the 'amazon-ecs' gem? - ruby-on-rails

I am using Amazon Product Advertising API (amazon-ecs) gem, but I am using the item_lookup method instead of item_search, which is the only one documented.
I am looking to return the item TradeInValue but I am confused as to how to do that. It is clearly being returned, but I am not sure how to parse it.
This is the call:
Amazon::Ecs.item_lookup('9780521153348', :response_group => 'ItemAttributes', :id_type => 'ISBN', :search_index => 'Books')
And this is the return, which I am not sure what to do with. The methods in amazon-ecs don't seem to work for item_lookup and XPath isn't working either:

Okay, I figured it out. I was trying to treat item_lookup as a single return value, rather than a hash the way search is returned.
item_lookup is basically the same as item_search:
res = Amazon::Ecs.item_lookup('9780521153348', :response_group => 'ItemAttributes', :id_type => 'ISBN', :search_index => 'Books')
res.items.each do |item|
puts item.get('ItemAttributes/TradeInValue/FormattedPrice')
end

RESTier OData Function that support $expand and $filter

With the help of the RESTier team, I manage to create an RESTier function that return a list of my entity.
Here's the code
protected EdmModel OnModelExtending(EdmModel model)
{
var ns = model.DeclaredNamespaces.First(); // PointLoc.Data
var entityContainer = (EdmEntityContainer) model.EntityContainer;
var locationEntityType = (IEdmEntityType) model.FindDeclaredType(ns + "." + "Location");
var locationEntitySet = entityContainer.FindEntitySet("Locations");
var locationEntityTypeReference = new EdmEntityTypeReference(locationEntityType, false);
var locationEntityCollection = EdmCoreModel.GetCollection(locationEntityTypeReference);
var ambilLocationsByMarketId = new EdmFunction(ns, "AmbilLocationsByMarketId", locationEntityCollection, false, null, true);
model.AddElement(ambilLocationsByMarketId);
entityContainer.AddFunctionImport("AmbilLocationsByMarketId", ambilLocationsByMarketId,
new EdmEntitySetReferenceExpression(locationEntitySet));
return model;
}
And here's my implementation on the Controller
[HttpGet]
[EnableQuery]
[ODataRoute("AmbilLocationsByMarketId")]
public IQueryable<Location> AmbilLocationsByMarketId()
{
var locations = DbContext.Locations.Where(l => l.Name.Contains("Hotel")).Select(l => l);
return locations;
}
It works fine returning the list of data with i send a HTTP GET to
http://localhost:21922/odata/AmbilLocationsByMarketId
but when I try to add $expand or $filter, It's not working.
http://localhost:21922/odata/AmbilLocationsByMarketId?$expand=Category
I'm Error that reads like

dispalay tag table pass value to requestURI

How do I set value to requestURI by action class in Struts2 or another form. I need to change value of requestURI according to tile.

Option 1: Pass value from action (Better way)
In yourAction.java
private String myActionName;
public String execute() {
myActionName="action1.action";
return SUCCESS;
}
public void setMyActionName(String myActionName) {
this.myActionName = myActionName;
}
public String getMyActionName() {
return myActionName;
}
In jsp file
<display:table id="u" name="userlist" pagesize="10" requestURI="${myActionName}" >
...
</display:table>
If you want to pass your own parameter in url
<s:url action="%{myActionName}" var="requrl" >
<s:param name="myparam">myvalue1</s:param>
</s:url>
<display:table id="u" name="userlist" pagesize="10" requestURI="${requrl}" >
...
</display:table>
Option 2: Pass value from tile (Not Recommanded)
In tiles.xml
<definition name="baseLayout" template="/BaseLayout.jsp">
<put-attribute name="title" value="" type="string" />
<put-attribute name="header" value="/Header.jsp" />
<put-attribute name="menu" value="/Menu.jsp" />
<put-attribute name="body" value="" />
<put-attribute name="footer" value="/Footer.jsp" />
<put-attribute name="myattribute" value="" type="string" />
</definition>
<definition name="/welcome.tiles" extends="baseLayout">
<put-attribute name="title" value="Welcome" type="string" />
<put-attribute name="body" value="/Welcome.jsp" />
<put-attribute name="myActionName" cascade="true" value="tileAction1.action" />
</definition>
Note: Use proper tiles version and tiles.xml dtd to use cascade="true".
In welcome.jsp
<tiles:useAttribute name="myActionName" />
<display:table id="u" name="userlist" pagesize="10" requestURI="${myActionName}" >
...
</display:table>

render composite component based on a Boolean condition

I developed a composite JSF 2 component, and it is working pretty well.
In one of the pages where I use my custom component, it is necessary that composite component should be rendered according to a boolean condition.
Pretty Much similar as the rendered attribute works in JSF standard components.
So I tried to implement it like this:
<cc:interface componentType="ciudadComponent">
<cc:attribute name="paises" type="java.util.List" required="true" />
<cc:attribute name="departamentos" type="java.util.List" required="true" />
<cc:attribute name="ciudades" type="java.util.List" required="true" />
<cc:attribute name="name" type="java.lang.String" required="true" />
<cc:attribute name="value" type="org.colfuturo.model.to.CiudadTO" required="true"## Heading ## />
<cc:attribute name="etiquetaPais" type="java.lang.String" />
<cc:attribute name="etiquetaBotonOK" type="java.lang.String" />
<cc:attribute name="etiquetaBotonCancelar" type="java.lang.String" />
<cc:attribute name="etiquetaDepartamento" type="java.lang.String" />
<cc:attribute name="etiquetaCiudad" type="java.lang.String" />
<cc:attribute name="styleClass" type="java.lang.String" />
<cc:attribute name="backGroundColor" type="java.lang.String" default="#b0c4de" />
<cc:attribute name="rendered" type="java.lang.Boolean" required="false" default="true" />
</cc:interface>
<cc:implementation>
<h:inputText id="seleccionado" binding="#{cc.seleccionado}" disabled="true" rendered="#{cc.rendered}">
<f:converter converterId="CiudadConverter" />
</h:inputText>
</cc:implementation>
In the page where I insert the composite component, it is like this:
<gambatte:ciudad
paises="#{menuTreeBean.listaPaises}"
departamentos="#{menuTreeBean.listaDepartamentos}"
ciudades="#{menuTreeBean.listaCiudades}" styleClass="mySelectStyle"
etiquetaBotonOK="#{msg['perfil.common.btnOK']}" etiquetaBotonCancelar="#{msg['perfil.common.btnCancelar']}"
etiquetaPais="#{msg['perfil.common.lblPais']}"
etiquetaDepartamento="#{msg['perfil.common.lblDepartamento']}"
etiquetaCiudad="#{msg['perfil.common.lblCiudad']}" name="otraSedeCiudad"
value="#{EstudiosRealizadosBean.otraSedeCiudad}"
rendered="#{EstudiosRealizadosBean.showOtraSede()}" />
The method EstudiosRealizadosBean.showOtraSede() returns java.lang.Boolean.
I get the following Exception when rendering the page:
java.lang.IllegalArgumentException: rendered
How can I solve this ?
I have also tried to put a boolean condition, but the same exception is raised
I am posting my whole component code:

Get rid of <cc:attribute name="rendered">.
It's already defined in UIComponent class, which <cc:implementation> extends from. You don't need to redefine it. The same story applies to id and binding attributes, by the way.
You also don't need to re-apply rendered="#{cc.rendered}" on the composite component's first child. You can also just get rid of it. The <my:composite rendered> already applies on the whole composite component itself.

Nested tool-bar button in xul

I am having a toolbar-button with type "menu-button". Can I have two toolbar-buttons inside this one?

Since you would like to have a button inside a menu-button, here you go. But, this is not a pretty good UI.

"An item with the same key has already been added" error when calling Context AddObject

Can somebody please help me with this error. I have an ASP.NET WebApp, within the Entity Model I have an entity called tb_AdminUser, with a UserID property as GUID. This is also the Entity Key. The entity is not in any relationship with any other entity. I get the error when calling the AddObject() function.
In my code I call the following...
SQL2008R2_824852_leapdbEntities temp = new SQL2008R2_824852_leapdbEntities();
tb_AdminUser au = new tb_AdminUser();
au.UserID = Guid.NewGuid();
au.Username = "TEST";
au.Password = "pete#webinspired.net";
au.LockedOut = false;
au.Surname = "Feehan";
au.Forename = "Pete";
temp.tb_AdminUser.AddObject(au); //error occurs here
temp.SaveChanges();
The EDMX XML Code is as follows
<EntityType Name="tb_AdminUser">
<Key>
<PropertyRef Name="UserID" />
</Key>
<Property Name="UserID" Type="uniqueidentifier" Nullable="false" />
<Property Name="Forename" Type="nvarchar" Nullable="false" MaxLength="50" />
<Property Name="Surname" Type="nvarchar" Nullable="false" MaxLength="50" />
<Property Name="Username" Type="nvarchar" Nullable="false" MaxLength="50" />
<Property Name="Password" Type="nvarchar" Nullable="false" MaxLength="50" />
<Property Name="LockedOut" Type="bit" Nullable="false" />
</EntityType>
