Bug or Feature Request:
How to serialize int array?
Description:
I have a column that is of type int[]:
@Table(name = "Notes", database = AppDatabase.class)
public class Note extends Model {
@PrimaryKey
private Long id;
@Column(name = "title")
private String title;
@Column(name = "text")
private String text;
@Column(name = "color")
private int color;
@Column(name = "numbers")
private int[] numbers;
}I want to serialize it as String (e.g. "[1,2,3]") so I made an IntArraySerializer:
public class IntArraySerializer extends TypeSerializer<int[], String> {
@Nullable
@Override
public String serialize(@Nullable int[] data) {
if (data == null) return null;
return new Gson().toJson(data);
}
@Nullable
@Override
public int[] deserialize(@Nullable String data) {
if (data == null) return null;
return new Gson().fromJson(data, int[].class);
}
}But when I call ReActiveAndroid.init()
DatabaseConfig appDatabaseConfig = new DatabaseConfig.Builder(AppDatabase.class)
.addModelClasses(Note.class, Folder.class, NoteFolderRelation.class)
.addTypeSerializers(IntArraySerializer.class)
.disableMigrationsChecking()
.build();
ReActiveAndroid.init(new ReActiveConfig.Builder(this)
.addDatabaseConfigs(appDatabaseConfig)
.build());app crashes with following error:

hello again,
if the database contents are empty, it throwing the error below
but,
with try catch, the solution can be found, but would not it be better for the library itself to check it?

Bug or Feature Request:
Access to method of pulling data from DB as Pagination
Description:
Another great feature I would like to see is access to API method of basic Pagination fetching;
User can, via code, pull List via pagination:
where("id > ?", lastId)public List<> fetchPagination(Long firstId, Long lastId, int limit, String orderBy, db.class myModelClass) {
List<myModelClass> result = new ArrayList<myModelClass>();
String defaultSortBy = "DESC";
if(sortBy !=null){
defaultSortBy = sortBy;
}
List<myModelClass> myModelClassList = Select.from(myModelClass.class).where("id > ?", lastId)
.orderBy("id " + defaultSortBy)
.limit(limit)
.fetch();
result = myModelClassList ;
return result;
}
I use the above internally to do this, however would be great if was accessible via API within the library.
I'm using version 1.4.2
Is there support of transaction for bulk insertions?
I have to insert 3600 records at first launch and it takes almost 1 minute.

ReActiveAndroid Version: 1.4.3
I am migrating from ActiveAndroid where I used to build a database dynamically and set the database file location using Configuration.Builder.setDatabaseName(name) to the external files directory (e.g. /sdcard/Android/data/ch.photrack.discharge/files/discharge.db). That way database file can be directly accessed by user for debugging and exporting.
Is there a way to change the default location of database file in ReActiveAndroid? If not, how can I preserve data in already existing ActiveAndroid database file located in external files directory when user updates app to the version with ReActiveAndroid?
I need to enable Cascade on Delete in my database. I was wondering if that would be the default behaviour but I guess it doesn't matter if I didn't specify a Foreign Key in my class. Also, the Relationship part is missing in the documentation.

Hi,
I have an issue with adding columns then updating the version number as I get the below log error (and crash)
Caused by: java.lang.IllegalStateException: ReActiveAndroid cannot verify the data integrity. Looks like you've changed schema but forgot to update the version number. You can simply fix this by increasing the version number.
I do update the version number & remove .disableMigrationsChecking() but still get crashes on launch.
Prior to the changes the application DB interactions work as intended.

Aiming to get results from a query using just the below without passing an id, as the docs state .where() needs a id as first param ...
"The second parameter is to pass the query arguments"
Note note = Select.from(TodayInfo.class).where("title = LIKE '?%'", query).fetchSingle();
I am also getting the below error even with straight up docs example ..

Is there .exists() method in ReActiveAndroid like there was in ActiveAndroid? Maybe under a different name? Thank you in advance
This is my first comment so sorry if it isn't structured the way it should.
Im using a model with a costume variable with the type org.joda.time.DateTime, i've added a costume serializer for this type but im getting a NullPointerException. This Exception occurs on line 95 in the SQLiteUtils.java file and it's because the type of the column is null.
I think the problem has to do with line 45 and 46 in the file DatebaseInfo.java, the custom serializers are loaded after the models. Can you verify this or am i doing something wrong?
DatebaseInfo.java
public DatabaseInfo(Context context, @NonNull DatabaseConfig databaseConfig) {
loadModels(context, databaseConfig); //These two lines
loadTypeSerializers(databaseConfig); //These two lines
this.reActiveOpenHelper = new ReActiveOpenHelper(context, databaseConfig, tableInfos.values());
ReActiveLog.i(LogLevel.BASIC, "Tables info for database " + databaseConfig.databaseName + " loaded.");
}My Serializer class:
public final class DateSerializer extends TypeSerializer<DateTime, Long> {
@Nullable
public Long serialize(@NonNull DateTime date) {
return date.getMillis();
}
@Nullable
public DateTime deserialize(@NonNull Long date) {
return new DateTime(date);
}

I deleted a field from my model, and incremented the database version:
@Database(name = "propertyforce", version = 19)
public class AppDatabase {
It was 18 before. Here's how I'm initializing:
DatabaseConfig appDatabase = new DatabaseConfig.Builder(AppDatabase.class)
.addModelClasses(LogEntry.class, FarmReport.class, FarmReportProperty.class)
.disableMigrationsChecking() // Potentially destructive, so replace with migrations if adding any tables that need to persist
.addTypeSerializers(JsonSerializer.class)
.build();
ReActiveAndroid.init(new ReActiveConfig.Builder(context)
.addDatabaseConfigs(appDatabase)
.build());
So I shouldn't need any migrations. Why is this happening?
Hi dear,
How can I select distinct in ReActiveAndroid, I'm trying to select this way but it requires Object as parameter but not model class
Select.distinct().from(...)
I'm using version 1.4.3

I am displaying notifications in a recyclerview and would like to order it by showing the newest notification on top. I've tried using orderBy("timestamp"), but it orders it from oldest to newest. timestamp is saved as a long which is basically me saving System.currentmillis() whenever a new notification is received. How can I reverse the current ordering?
notificationses = Select.from(Notifications.class).orderBy("timestamp").fetch();

Use multiple Where clauses when using fetch()
Description:
There is still an issue where I wish to return all (or paginated) data filtered by the query using fetch() which returns the error of Cannot bind argument at index 2 because the index is out of range. The statement has 1 parameters
All the documentation advises only of using fetchSingle() when using multiple Where clauses
I wish not to return only the first hit, but all (or some) data items.
fetch() has not been implemented for using multiple Where clausesfetch() with multiple clauses would require List<> return typeReActiveAndroid Version: 1.4.3
Bug or Feature Request: Multiple WHERE clauses in query
Description: I'm trying to migrate from ActiveAndroid to REActiveAndroid but having some problems with multiple WHERE clause migrations.
The old way to do it in AA was like:
Note note = Select.from(Note.class).where("noteId = ?", username).where("noteContent= ?", content).fetchSingle();
Now, according to this migration guide: https://imangazalievm.gitbooks.io/reactiveandroid/migration-from-activeandroid.html we're supposed to do it this way:
List<Note> notes = Select.from(Note.class).fetch();
List<Note> notes = Select.from(Note.class).execute();
Note note = Select.from(Note.class).where("id=? AND title LIKE '?%'", 1, "Hello").fetchSingle();
There's several problems with this. First, "notes" is defined twice, Second ".execute();" cannot be resolved by Android Studio, and third (and perhaps most importantly) when I build it like the tutorial states, I get:
java.lang.IllegalArgumentException: Cannot bind argument at index 2 because the index is out of range. The statement has 1 parameters.
Why this change? What should I do to fix it?

Bug or Feature Request:
Feature
Description:
Be able to pass set data to Method to update all values passed, which would save many manually written hard-coded methods within app;
Would tie in nicely with Transaction API as you could pass all this and use transaction via one API call
Example:
fetch data from server and set data like below;
//set temp model data in activity/fragment/service/response
Note myModelUsedForReActiveAndroid = new Note();
dataHolder.setTitle("title from server");
dataHolder.setText("text from server");
dataHolder.setUpdateAt("date from server");
updateViaCRUD(Note.class, dataHolder );
then pass to API to process an do CRUD in one action;
public static Boolean updateViaCRUD(Class<?> table, Model<?> myModelUsedForReActiveAndroid) {
boolean result = false;
//check if data item already exists
//update all values or;
//create new values
//if save success
//result = true;
return result;
}
Ex.
CREATE TABLE `Example` (
`id` INTEGER PRIMARY KEY AUTOINCREMENT UNIQUE,
`timestamp` **DATETIME DEFAULT CURRENT_TIMESTAMP**
);
How can I create a table like the one above?
I have just migrated from ActiveAndroid due to errors on Android 8+
The problem is that my app comes with db-first approach. The database, which has all the tables and data, gets installed with app. In ActiveAndroid I used to have my db in assets folder and it would handle the else correctly. However after migration the fetch commands return empty. I think the db file in assets is not used and ReActiveAndroid just creates a new one.
The filename is in 'mydatabase.db' format and my appdatabase.js:
@Database(name = "mydatabase", version = 1)
public class AppDatabase {
}
So is there something that I'm missing?
Hi,
How can we backup and restore the database?

Hi,
I'm currently migrating an app from ActiveAndroid to ReActiveAndroid. One of the issues I've run into is the lack of a getId() method from the Model class that was present in ActiveAndroid. Some of my Model classes rely on this method. Is there some other way to retrieve the Model ID inside a Model class?
Any help would be appreciated, thank you.

I am trying to migrate from activeandroid to reactiveandroid. I need to add an enum class as column within a model class, how to do that in reactive-android?
I am using fetchSingle() to check if any hits (via "id", 1) and get hit with E/SQLiteLog: (1) near "LIMIT": syntax error when processing (I know no rows in related queried table) but should return 0 or a false value but instead get Exception error ...

I have, on launch a scenario of comparing local string & server side string, and on false, I run an update to my DB which has data pulled from API (~15k items) in which I pass this data to public static helper to do DB updates on the tables;
Problem is when I use begin/end transaction in this method(), even though the save() passes true, nothing gets actually added or updated (get count of 0), but if I remove the begin/end transaction everything gets updated/created in the DB as i should (get count of ~15k) but is very slow and not ideal at all;
Also both types freeze the UI indefinitely until task completed;
