由 青春壹個敷衍的年華 提交于 2021-02-08 02:56:49
问题 I am using Dexie IndexedDB wrapper and I am trying to add an object to an existing array which in inside a nested object. The structure looks similar to below { Name : 'John', age : 33, tags : { skill: [{ first: '.NET', second: 'JAVA', third: [{special1:'sleep'},{special2:'eat'}] }] } } I have tried many way to push object special3:'run' to skill.third but without success. My last attempt looked something like this const pathObject = {}; const fullPath = 'result.tags.skill[3].third';

问题 I have a table where each object has a field that is an array of strings: for example, { people: ['John', 'Bob', 'Sue'] } . I need all objects in the table that have 'Sue' in the people array.

问题 Edit. I rewrote the code to be even more minimalist. The below code is a spike test of my issue. Here is a video of the issue: https://imgur.com/a/WI2wHMl I have two components. The first component is named TextEditor (and it is a text editor) but its content is irrelevant - the component could be anything. A simple div with text would be just as relevant. The next component is named Workflows and is used to render a collection from IndexDB (using the Dexie.js library). I named this

Dexie.js Autoincrement Primary Key - does it ever reset? How to reset it?

由 南楼画角 提交于 2019-12-11 10:07:04
问题 In Dexie.js you can create a store with an auto-incrementing key let db = new Dexie("nav_api"); db.version(1).stores({ jobs: '++id, json' }); So to test, I created 14 objects in the db via db.jobs.put({json: '[]'}) , and all their keys came out as expected, started at 1 up to 14. Then deleted some of the later ones, db.jobs.where('id').above(6).delete() , and added another one to the db, and its index was 15. Is there any way to reset the index to 0? I was using it for ordering, and I'm not
