<a href="/movies/<!-- Movie ID -->/add_review"><button>Add Review</button></a>

Template (add_review.html):

<!-- Jinja extends -->
         <h1>Add a New Review for <!-- Jinja Movie Name --></h1>
         <form action="/movies/(jinja movie id)/add_review" method="post">
           <label for="user">User:</label>
           <input type="text" id="user" name="user" required><br>

Handle Form Submission in Flask¶

Route to Display Form:

@app.route('/movies/<movie_id>/add_review')
def add_review(movie_id):
    movie = mongo.db.movies.find_one({'_id': ObjectId(movie_id)})
    return render_template('add_review.html', movie=movie)

Route to Handle Form Submission:

@app.route('/movies/<movie_id>/add_review', methods=['POST'])
def add_review_post(movie_id):
    user = request.form['user']
    rating = request.form['rating']
    comment = request.form.get('comment')

    review = {
        'user': user,
        'rating': rating,
        'comment': comment
    }

    mongo.db.movies.update_one(
        {'_id': ObjectId(movie_id)},
        {'$push': {'reviews': review}}
    )
    return redirect(f'/movies/{movie_id}')

Implementation of Cast creation¶

    <h1>Add a New Cast Member</h1>
    <form action="/add_cast" method="post">
      <label for="name">Name:</label>
      <input type="text" id="name" name="name" required><br>

      <label for="date_of_birth">Date of Birth:</label>
      <input type="date" id="date_of_birth" name="date_of_birth" required><br>
