```
__tablename__ = 'listings'
id = Column(Integer,primary_key=True,autoincrement=True)
link = Column(String,unique=True)
title = Column(String)
img = Column(String,unique=True)
name = Column(String)
```
error code :
```
UNIQUE constraint failed: listings.img [SQL: 'INSERT INTO listings (link,
title, img, name) VALUES (?, ?, ?, ?)']
```
