class Artist(db.Model):
id = db.Column(db.Integer(), primary_key=True)
artist_name = db.Column(db.String(200))
albums = db.relationship('Album',
backref='artist',
lazy=True)
def __repr__(self):
return "<Artist '{}'>".format(self.artist_name)
这是测试班
def test_artists_count(self):
c = Artist.query.all()
self.assertEqual(2, c)
这是我遇到的错误
Traceback (most recent call last):enter code here
File "/projects/challenge/myflaskproj/tests/test_models.py", line 65, in test_artists_count
self.assertEqual(2, c)
AssertionError: 2 != [<Artist 'Artist1'>, <Artist 'Artist2'>]
答案 0 :(得分:0)
您可以通过检查查询结果的长度来检查查询结果的行数或行数
您唯一需要更改的行是:
self.assertEqual(2, len(c))
