FAQs on Django Tutorial 15 Adding Songs to Database Video Lecture - Django: The Ultimate Beginners Guide (in Hindi) - Back-End Programming
| 1. How do I add songs to the database using Django? |  |
Ans. To add songs to the database using Django, you need to perform the following steps:
1. Create a new model in your Django application to represent the song, including relevant fields such as title, artist, and duration.
2. Run the migrations to create the corresponding table in the database.
3. Use Django's ORM (Object-Relational Mapping) to create instances of the song model and save them to the database.
| 2. Can I add multiple songs at once to the Django database? | |
Ans. Yes, you can add multiple songs at once to the Django database. You can achieve this by using Django's bulk_create() method. This method allows you to create multiple instances of a model and save them to the database in a single database query, which can be more efficient than saving each instance individually.
| 3. How can I retrieve songs from the Django database? | |
Ans. To retrieve songs from the Django database, you can use Django's ORM. You can perform queries using the model's manager, which provides methods like all() to retrieve all instances of a model or filter() to retrieve specific instances based on certain criteria. For example, you can use Song.objects.all() to retrieve all songs from the database.
| 4. How can I update the details of a song in the Django database? | |
Ans. To update the details of a song in the Django database, you can retrieve the specific song instance using queries, modify its fields, and then save it back to the database. For example, you can use the following code to update the title of a song with a specific ID:
```
song = Song.objects.get(id=song_id)
song.title = "New Title"
song.save()
```
This will update the title of the song in the database.
| 5. How can I delete a song from the Django database? | |
Ans. To delete a song from the Django database, you can retrieve the specific song instance using queries and then call the delete() method on the instance. For example, you can use the following code to delete a song with a specific ID:
```
song = Song.objects.get(id=song_id)
song.delete()
```
This will remove the song from the database.
