Hi there!
I am working on the project X-press publishing: https://www.codecademy.com/paths/web-development/tracks/building-a-persistent-api/modules/persistent-api-cumulative-projects/projects/x-press-publishing
I’ve got two annoing SQLite errors on PUT and DELETE. Despite the test is passed there are two errors “Error: SQLITE_CONSTRAINT: NOT NULL constraint failed: Artist.name”:
PUT /api/artists/:id
Error: SQLITE_CONSTRAINT: NOT NULL constraint failed: Artist.name
PUT /api/artists/1 200 8.203 ms - 135
√ should update the artist with the given ID
PUT /api/artists/1 200 6.183 ms - 135
√ should return a 200 status code after artist update
PUT /api/artists/1 200 6.273 ms - 135
√ should return the updated artist after artist update
PUT /api/artists/1 400 0.680 ms - -
√ should return a 400 status code for invalid artist updates
DELETE /api/artists/:id
Error: SQLITE_CONSTRAINT: NOT NULL constraint failed: Artist.name
DELETE /api/artists/1 200 6.769 ms - 122
√ should set the artist with the given ID as not currently-employed
DELETE /api/artists/1 200 6.405 ms - 122
√ should return a 200 status code after artist delete
DELETE /api/artists/1 200 5.953 ms - 122
√ should return the deleted artist after artist delete
My PUT and DELETE look like that:
artistsRouter.put('/:artistId', (req, res, next) => {
const name = req.body.artist.name;
const dateOfBirth = req.body.artist.dateOfBirth;
const biography = req.body.artist.biography;
const isCurrentlyEmployed = req.body.artist.isCurrentlyEmployed === 0 ? 0 : 1;
if (!name || !dateOfBirth || !biography) {
res.status(400).send();
};
db.run(`UPDATE Artist
SET name = $name,
date_of_birth = $dateOfBirth,
biography = $biography,
is_currently_employed = $isCurrentlyEmployed
WHERE id = $id`,
{$name: name,
$dateOfBirth: dateOfBirth,
$biography: biography,
$isCurrentlyEmployed: isCurrentlyEmployed,
$id: req.params.artistId},
(err) => {
if (err) {
next(err);
} else {
db.get(`SELECT * FROM Artist WHERE id = ${req.params.artistId}`, (err, artist) => {
res.status(200).send({artist: artist});
});
};
});
});
artistsRouter.delete('/:artistId', (req, res, next) => {
db.run(`UPDATE Artist
SET is_currently_employed = 0
WHERE id = ${req.params.artistId}`,
(err) => {
if (err) {
next(err);
} else {
db.get(`SELECT * FROM Artist WHERE id = ${req.params.artistId}`, (err, artist) => {
res.status(200).send({artist: artist});
});
};
});
});
My migration.js looks like that:
const sqlite3 = require('sqlite3');
const db = new sqlite3.Database('./database.sqlite');
db.serialize(() => {
db.run(`DROP TABLE IF EXISTS Artist`);
db.run(`CREATE TABLE IF NOT EXISTS Artist (
id INTEGER PRIMARY KEY NOT NULL,
name TEXT NOT NULL,
date_of_birth TEXT NOT NULL,
biography TEXT NOT NULL,
is_currently_employed INTEGER DEFAULT 1
)`);
});
The application works properly. Do you have any ideas why this SQLITE_CONSTRAINT occurs?
