Hi ,
I am new at couchbase sync-gateway configuration . I need clear steps for How to add config.json file ? Here is my config.json
{
“interface”: “:4984”,
“adminInterface”: “:4985”,
“log”: [“REST”],
“databases”: {
“db”: {
“server”: “http://SERVER_IP:8091”,
“users”: {“GUEST”: {“disabled”: false, “admin_channels”: [“*”]}},
“bucket”: “default”,
“sync”: function(doc) {channel(doc.channels);}
}
}
}
Here is output when i start sync_gateway

What is the error there ? Can you please explain how to test sync from Android ?
this means your sync function has changed ,all your data in default bucket on http://SERVER_IP:8091 may assign different channels to documents, you can re-sync to update channels for documents.
you can start pull/push sync with sync gateway,and add/modify document from Android and sync gateway, and get change from _changes api by SDK or by REST API.
here is a example for Android, FYI.
Hi, I tried to sync from android .But failed. i tried http://serverip:8091/bucket_name . Can you please tell me why it’s failed?
When i send request this http://server_ip:8091/default Respone is : Not found
what do you mean this?
you should start pull/push sync with sync gateway,and add/modify document from Android ,and then get document from Sync Gateway to verify by access http://<SyncGateway_ServerIP>:4984/db/
Can you tell me How to re-sync for update channels? I am very new at couchbase .
Hi, I tried to re-sync the channel, but it says database must offline to re-sync . Do i must need to re-sync now ?
Hi ,
I added android code for test sync . Here is ther Logs
My Sync url : http:serverip:8091/databasename , is it right?
Logs:
/Sync: Change tracker stopped during continuous replication

Sync url should be
http://SyncGatewayServerIP:4984/db/
Yes. I added . After that , Logs

Here is my start sync Method
public void start_sync_gateway() {
URL url = null;
try {
url = new URL(mSyncGatewayUrl);
} catch (MalformedURLException e) {
e.printStackTrace();
}
pusher = database.createPushReplication(url);
pusher.setContinuous(true); // Runs forever in the background
puller = database.createPullReplication(url);
puller.setContinuous(true); // Runs forever in the background
pusher.start();
puller.start();
}
Here is My onCreate Method
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create a manager

try {
manager = new Manager(new AndroidContext(getApplicationContext()), Manager.DEFAULT_OPTIONS);
} catch (IOException e) {

}

try {

} catch (CouchbaseLiteException e) {
e.printStackTrace();
}

Map<String, Object> properties = new HashMap<String, Object>();
properties.put(“title”, “Couchbase Mobile”);

try {
document.putProperties(properties);

start_sync_gateway();
}
i replaced server key’s value as 127.0.0.1:8091 at config.json file . Is it ok ?
that means your CB server and SG server on the same machine.
ok. But i can’t add any Document at my Bucket. How can i do it ? can you please explain ?
I installed sync_gateway in my cloude server . So, is my config.json file right ? How to call from syncURL . Can you please give me short description ?
that means your CB server and SG server on the same machine.
you can test from SG first by send HTTP request for documents CRUD
FYI
for example
curl -X PUT -H "Content-Type:application/json" http://your_cloud_server:4984/db/doc1--data '{"some_key":"some value"}'
then From Android Couchbase Lite,there is also a HTTP REST API you can use.
FYI
I got this
{“error”:“Bad Request”,“reason”:“Bad JSON”}curl: (6) Could not resolve host: “some_key”
should be
curl -X PUT -H "Content-Type:application/json" http://your_cloud_server:4984/db/doc1 --data '{"some_key":"some value"}'
Same output
:~$ curl -X PUT -H “Content-Type:application/json” http://ip:4984/db/{doc id}–data ‘{“created_by”:“3”}’
{“error”:“Bad Request”,“reason”:“Bad JSON”}curl: (6) Could not resolve host: “created_by”
there should be at least a Space between {doc id} and --data
