Write a program to make a platform to upload watch and share video and write comments
Here's a basic outline of how you can create a video sharing platform using Python and the Flask web framework:
```
from flask import Flask, render_template, request, redirect, url_for
from flask_sqlalchemy import SQLAlchemy
from werkzeug.utils import secure_filename
import os
app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"] = "sqlite:///video.db"
db = SQLAlchemy(app)
class Video(db.Model):
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(100), nullable=False)
description = db.Column(db.Text, nullable=False)
filename = db.Column(db.String(100), nullable=False)
comments = db.relationship("Comment", backref="video", lazy=True)
class Comment(db.Model):
id = db.Column(db.Integer, primary_key=True)
content = db.Column(db.Text, nullable=False)
video_id = db.Column(db.Integer, db.ForeignKey("video.id"), nullable=False)
@app.route("/")
def index():
videos = Video.query.all()
return render_template("index.html", videos=videos)
@app.route("/upload", methods=["GET", "POST"])
def upload():
if request.method == "POST":
title = request.form["title"]
description = request.form["description"]
file = request.files["file"]
filename = secure_filename(file.filename)
file.save(os.path.join("static/videos", filename))
video = Video(title=title, description=description, filename=filename)
db.session.add(video)
db.session.commit()
return redirect(url_for("index"))
return render_template("upload.html")
@app.route("/video/<int:video_id>")
def video(video_id):
video = Video.query.get_or_404(video_id)
comments = video.comments
return render_template("video.html", video=video, comments=comments)
@app.route("/comment/<int:video_id>", methods=["POST"])
def comment(video_id):
video = Video.query.get_or_404(video_id)
content = request.form["content"]
comment = Comment(content=content, video=video)
db.session.add(comment)
db.session.commit()
return redirect(url_for("video", video_id=video_id))
if __name__ == "__main__":
app.run(debug=True)
```
This code creates a basic video sharing platform with the following features:
- Users can upload videos with a title, description, and file.
- Videos are displayed on the homepage with their title, description, and a link to watch the video.
- Users can watch videos and leave comments.
- Comments are displayed below the video.
To run this code, you'll need to:
1. Install Flask and Flask-SQLAlchemy using pip: `pip install flask flask-sqlalchemy`
2. Create a new file called `app.py` and paste the code into it.
3. Create a new directory called `templates` and create the following HTML files inside it: `index.html`, `upload.html`, and `video.html`.
4. Create a new directory called `static` and create a new directory called `videos` inside it. This is where the uploaded videos will be stored.
5. Run the code using `python app.py` and open your web browser to `http://localhost:5000`.
Here's an example of what the HTML files might look like:
`index.html`:
```
<!DOCTYPE html>
<html>
<head>
<title>Video Sharing Platform</title>
</head>
<body>
<h1>Video Sharing Platform</h1>
<ul>
{% for video in videos %}
<li>
<a href="{{ url_for('video', video_id=video.id) }}">{{ video.title }}</a>
</li>
{% endfor %}
</ul>
<p><a href="{{ url_for('upload') }}">Upload a new video</a></p>
</body>
</html>
```
`upload.html`:
```
<!DOCTYPE html>
<html>
<head>
<title>Upload a new video</title>
</head>
<body>
<h1>Upload a new video</h1>
<form action="" method="post" enctype="multipart/form-data">
<label for="title">Title:</label>
<input type="text" id="title" name="title"><br><br>
<label for="description">Description:</label>
<textarea id="description" name="description"></textarea><br><br>
<label for="file">File:</label>
<input type="file" id="file" name="file"><br><br>
<input type="submit" value="Upload">
</form>
</body>
</html>
```
`video.html`:
```
<!DOCTYPE html>
<html>
<head>
<title>{{ video.title }}</title>
</head>
<body
```
Here is the rest of the `video.html` template:
```
<!DOCTYPE html>
<html>
<head>
<title>{{ video.title }}</title>
</head>
<body>
<h1>{{ video.title }}</h1>
<p>{{ video.description }}</p>
<video width="320" height="240" controls>
<source src="{{ url_for('static', filename='videos/' + video.filename) }}" type="video/mp4">
Your browser does not support the video tag.
</video>
<h2>Comments:</h2>
<ul>
{% for comment in comments %}
<li>{{ comment.content }}</li>
{% endfor %}
</ul>
<form action="" method="post">
<label for="content">Leave a comment:</label>
<textarea id="content" name="content"></textarea>
<input type="submit" value="Comment">
</form>
</body>
</html>
```
This template displays the video title, description, and the video itself. It also displays a list of comments and a form to leave a new comment.
To run this code, you'll need to create a new directory called `templates` and add the `index.html`, `upload.html`, and `video.html` files to it.
You'll also need to create a new directory called `static` and add a new directory called `videos` to it. This is where the uploaded videos will be stored.
Finally, you can run the code using `python app.py` and open your web browser to `http://localhost:5000`.
Note: This is a very basic example and you should consider adding more features such as user authentication, video processing, and security measures to prevent unauthorized access.
Here is the rest of the code:
```
if __name__ == "__main__":
app.run(debug=True)
```
This code starts the Flask development server, which will automatically reload the application if any changes are made to the code.
To run this code, save it to a file called `app.py` and run it using `python app.py`. Then, open your web browser and navigate to `http://localhost:5000`.
You should see a webpage with a form to upload a new video. Fill out the form and submit it to upload a new video.
Once you've uploaded a video, you can view it by clicking on the link to the video. You can also leave comments on the video by filling out the comment form.
Note: This is a very basic example and you should consider adding more features such as user authentication, video processing, and security measures to prevent unauthorized access.
Also, this code uses a very simple database model and you may want to consider using a more robust database model and ORM (Object Relational Mapping) tool.
You can also use a more robust framework such as Django which has built-in support for user authentication, video processing and security measures.
Please let me know if you have any questions or need further clarification.
