If you want to make a user-unique-and-crazy-key don't use the primary key of the table, create another column with this kind of data and you can generate a unique code using md5 of the unix microtime for example. The Human world are strange for databases, believe me or not! Let the keys to be keys, its nice and faster to table relationships.

- Jul 20, 2017 Updating and deleting from your Firebase Database. Nick Skelton. Jul 20, 2017 3 min read. A simple getting started guide to Firebase Database, a NoSQL database with a rich client side API.
- Nov 22, 2016 Firebase provides two primary event types for retrieving your data, value and childadded. The value event returns all child nodes in an unsorted JSON object and then returns all nodes every time there’s any change to any of the child nodes. The childadded event fires once for each existing child and then fires again every time a child is added.
- Note - Must change your Firebase Database URL in Main activity class before building the project. Now, go to Solution Explorer- Project Name- MainActivity and add the following code to main activity with appropriate namespaces.
- Apr 08, 2020 The unique key generated by push is based on a timestamp, so list items are automatically ordered chronologically. You can use the reference to the new data returned by the push method to get the value of the child's auto-generated key or set data for the child. Calling getKey on a push reference returns the value of the auto-generated key.

There's no AngularFire code here. Not really sure how this relates to the bindings lib. For an example of the API usage of push(), see here. |
