INSERT or IGNORE INTO product(id, name, creatorId) VALUES (6, 'Ionicons', 3) INSERT or IGNORE INTO product(id, name, creatorId) VALUES (5, 'Drifty Co', 3) INSERT or IGNORE INTO product(id, name, creatorId) VALUES (4, 'Drifty Co', 2) INSERT or IGNORE INTO product(id, name, creatorId) VALUES (3, 'Ionic Framework', 2) INSERT or IGNORE INTO product(id, name, creatorId) VALUES (2, 'Software Startup Manual', 1) INSERT or IGNORE INTO product(id, name, creatorId) VALUES (1, 'Ionic Academy', 1) INSERT or IGNORE INTO developer VALUES (3, 'Ben', '', '') ĬREATE TABLE IF NOT EXISTS product(id INTEGER PRIMARY KEY AUTOINCREMENT,name TEXT, creatorId INTEGER) INSERT or IGNORE INTO developer VALUES (2, 'Max', '', '') INSERT or IGNORE INTO developer VALUES (1, 'Simon', '', '') So for our case I created a simple file at assets/seed.sql and added this data for testing: CREATE TABLE IF NOT EXISTS developer(id INTEGER PRIMARY KEY AUTOINCREMENT,name TEXT,skills TEXT,img TEXT) You could also infject JSON data using the porter plugin as well! Ionic cordova plugin add uk.co.Īs said in the beginning, we will inject some initial seed data that you might have taken from your existing database. Npm install cordova plugin add cordova-sqlite-storage Now go ahead and run: ionic start devdacticSql blank -type=angular To get started we create a blank new app, add two pages and a service so we got something to work with and then install both the SQLite package and also the SQLite porter package plus the according Cordova plugins. This tutorial is by no means a general SQL introduction, you should know a bit about it when you incorporate this into your Ionic 4 app! Setting up our SQLite App But I can't be the only person who wants to build multiple different core data apps and wants to obsessively check the data during coding so I imagine there must be some timesaving tools or best practices out there.If your app needs a solid database or you already got data that you want to inject in your Ionic application, there’s the great underlying SQLite database inside that week can use just like any other storage engine to store our data.īut the usage of the SQLite database is a bit more tricky than simply using Ionic Storage, so in this tutorial we will go through all the steps needed to prepare your app, inject some seed data and finally make different SQL queries on our database.įor a more up to date tutorial also check out the Building an SQLite Ionic App with Capacitor! I suppose it would be good practice for me to write my own data browsing admin interface for each core data app that I write. There were no foreign keys and no linking tables between the many to many entities as far as I could see.) What is the equivalent in the SwiftUI and Core Data world? Do people write custom data browsers for their apps, with custom buttons to delete some / all rows, custom UI to query with predicates, etc.? Or do they use a tool like a SQLite browser? (For the Day 61 SwiftUI challenge, I tried using a SQLite browser but it didn't seem to be able to show me the relationships between entities. If I were doing a sql based web app, I'd be doing select and delete queries directly to the database as I was developing the frontend. Occasionally I want to start from scratch and delete all the sample data without having to delete the whole app in the simulator. As you can imagine, there's a phase of building an app where I'm iterating on the data model, building basic UI to save / load / edit / delete, and constantly checking to make sure data is saving correctly. Hi all, I'm trying to build Core Data apps and I'm wondering what sort of tools or practices to use in order to support my development.
