To create a test case, we’ll make a table:<\/p>\n

r.db('test').table('users').insert([{\n  first_name: 'gary',\n  last_name: 'sieling'\n},\n{\n  first_name: 'melissa'\n},\n{\n  last_name: 'a test'\n}])\n<\/pre>\n

If you try to re-insert these, you’ll get a duplicate key violation:<\/p>\n
\nr.db('test')\n .table('users')\n .insert({\n  id: '46454a3e-ba9e-4991-bc7f-53f1e5c19906',\n  first_name: 'test upsert 1',\n  last_name: 'test upsert 2'\n})\n<\/pre>\n
\nDuplicate primary key `id`:\n{\n  \"first_name\":\t\"gary\",\n  \"id\":\t\"46454a3e-ba9e-4991-bc7f-53f1e5c19906\",\n  \"last_name\":\t\"sieling\"\n}\n{\n  \"first_name\":\t\"test upsert 1\",\n  \"id\":\t\"46454a3e-ba9e-4991-bc7f-53f1e5c19906\",\n  \"last_name\":\t\"test upsert 2\"\n}\n<\/pre>\n
If you want to do an upsert, you can choose to either replace the entire object, or just matching keys.<\/p>\n
To replace the entire object:<\/p>\n
\nr.db('test').table('users').insert({\n  id: '46454a3e-ba9e-4991-bc7f-53f1e5c19906',\n  first_name: 'test upsert 1',\n  last_name: 'test upsert 2'\n}, {\n  conflict: 'replace'\n})\n<\/pre>\n
If you want to merge objects, you can do it with ‘update’:<\/p>\n
\nr.db('test').table('users').insert({\n  id: '46454a3e-ba9e-4991-bc7f-53f1e5c19906',\n  first_name: 'Gary'\n}, {\n  conflict: 'update'\n})\n<\/pre>\n
You can also use this to add new attributes to existing objects.<\/p>\n
Note that you can’t replace pieces of the object this way, as they will get replaced in their entirety:<\/p>\n
\nr.db('test').table('users').insert({\n  id: '46454a3e-ba9e-4991-bc7f-53f1e5c19906',\n  work_history: [\n    {title: 'Job 1'},\n    {title: 'Job 2'}\n  ]  \n}, {\n  conflict: 'update'\n});\n\nr.db('test').table('users').insert({\n  id: '46454a3e-ba9e-4991-bc7f-53f1e5c19906',\n  work_history: [\n    {employer: 'Employer 1'},\n    {title: 'Employer 2'}\n  ]  \n}, {\n  conflict: 'update'\n})\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
