Sample text

MongoDB is schema less, meaning each object stored in a collection does not need to have properties similar to other objects. This provides great flexibility for the developers to store heterogeneous pieces of data. In a relational database, a table schema provides a rigid structure to the data and the developer has to make sure to insert data that follows the schema, or else saving data will fail. If data requirements change or new properties are introduced, we would need to alter the underlying table to allow the change and/or provide a default value to the new property.

In the above query, we are trying to retrieve all tickets where the priority is either low or medium. We want the tickets to be ordered by created date in a descending order (that is, most recent first) and only return the title, priority, and category fields. The query is actually executed when the exec function is called. We can also chain the commands using dot syntax. 7 Query with a Single Operation The QueryBuilder makes it easy to compose complex queries and helps improve the code readability and maintainability.

Js in /routes/views/tickets. section is used to set the currently selected // item in the header navigation. render('tickets/ticketlist'); }; You just created your first KeystoneJS view. The tickets view takes the request and response object as the parameters. Remember that these parameters are required by all views.
