    <p>Is it possible to cache nested (2-3 level of nesting) objects (foreign fields) via Robospice/ORMlite? <a href="https://groups.google.com/forum/#!msg/robospice/VGLB3-vM3Ug/-piOac212HYJ" rel="nofollow">https://groups.google.com/forum/#!msg/robospice/VGLB3-vM3Ug/-piOac212HYJ</a> - there you can read that is possible, but unfortunatelly I can't achieve it.</p> <p>Here is my source code:</p> <pre><code>@DatabaseTable(tableName = "city") @JsonIgnoreProperties(ignoreUnknown = true) public class City { @DatabaseField(id = true) @JsonProperty("id") private long id; @DatabaseField @JsonProperty("name") private String name; @ForeignCollectionField(eager = true, maxEagerLevel = 3) @JsonProperty("clubs") private Collection&lt;Club&gt; clubs; ... @DatabaseTable(tableName = "club") @JsonIgnoreProperties(ignoreUnknown = true) public class Club { @DatabaseField(id = true) @JsonProperty("user_id") private long id; @DatabaseField @JsonProperty("name") private String name; @DatabaseField(foreign = true, foreignAutoRefresh = true, columnName = "city_id", maxForeignAutoRefreshLevel = 2) private City city; @DatabaseField(foreign = true) @JsonProperty("address") private VenueAddress address; ... @DatabaseTable(tableName = "address") @JsonIgnoreProperties(ignoreUnknown = true) public class VenueAddress { @DatabaseField(id = true) @JsonProperty("uid") private long id; @DatabaseField @JsonProperty("street") private String street; @DatabaseField @JsonProperty("street_number") private String streetNumber; @DatabaseField @JsonProperty("country") private String country; @DatabaseField(foreign = true, foreignAutoRefresh = true, columnName = "club_id", maxForeignAutoRefreshLevel = 2) private Club club; ... </code></pre> <p>And sample SpiceService:</p> <pre><code>public class SampleSpiceService extends SpringAndroidSpiceService { private static final int WEBSERVICES_TIMEOUT = 10000; @Override public CacheManager createCacheManager(Application application) { CacheManager cacheManager = new CacheManager(); List&lt;Class&lt;?&gt;&gt; classCollection = new ArrayList&lt;Class&lt;?&gt;&gt;(); // add persisted classes to class collection classCollection.add(VenueAddress.class); classCollection.add(City.class); classCollection.add(Club.class); // init RoboSpiceDatabaseHelper databaseHelper = new RoboSpiceDatabaseHelper(application, "sample_database.db", 5); InDatabaseObjectPersisterFactory inDatabaseObjectPersisterFactory = new InDatabaseObjectPersisterFactory( application, databaseHelper, classCollection); cacheManager.addPersister(inDatabaseObjectPersisterFactory); return cacheManager; } @Override public RestTemplate createRestTemplate() { RestTemplate restTemplate = new RestTemplate(); // set timeout for requests HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory(); httpRequestFactory.setReadTimeout(WEBSERVICES_TIMEOUT); httpRequestFactory.setConnectTimeout(WEBSERVICES_TIMEOUT); restTemplate.setRequestFactory(httpRequestFactory); MappingJacksonHttpMessageConverter messageConverter = new MappingJacksonHttpMessageConverter(); restTemplate.getMessageConverters().add(messageConverter); restTemplate.getMessageConverters().add(new StringHttpMessageConverter()); return restTemplate; } } </code></pre> <p>And when I fetch City object from cache it has clubs collection, but VenueAddress in each Club has null fields (except id). Do you have any advices? </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
