将请求 POST 中的数据添加到表模板中 [Django, Python]

Question

I create a table show book info from SQLite database and I'm trying to create an "Add New Book form" to make it add a new book into a table database. How can I add a book and then make it show into the table Book Info?

<div class="container-fluid">
    <!-- Add Book -->
    <div class="add-book">
        <h1>Add a Book</h1>
        <form action="/add_book" method="POST" class="add_more_book">
            {% csrf_token %}
            <p>
                <label for="title" id="title">Title:</label>
                <input type="text" name="title" class="form-control" id="input-title" />
            </p>
            <p>
                <label id="desc" for="desc">Description:</label>
                <textarea class="form-control" name="description" id="input-desc" rows="3"></textarea>
            </p>
            <button type="submit" class="btn shadow btn-primary" id="addbtn">
                Add
            </button>
        </form>
    </div>
    <!-- End of Add Book -->

    <!-- Book info -->
    <div class="book-info">
        <form action="/" method="POST">
            {% csrf_token %}
            <table class="table table-bordered">
                <thead>
                    <tr>
                        <th>ID</th>
                        <th>Title</th>
                        <th>Action</th>
                    </tr>
                </thead>
                <tbody>
                    {% for i in all_books_info %}
                    <tr>
                        <th scope="row">{{i.id}}</th>
                        <td>{{i.title}}</td>
                        <td><a href="/books/{{i.id}}">Views</a></td>
                    </tr>
                    {% endfor %}
                </tbody>
            </table>
        </form>
    </div>

Lets say you have an a table named Bio in your models.py file. Like so

    class Bio(models.Model):
        author = models.CharField(max_length= 20, null=True)
        book = models.CharField(max_length= 20, null=True)
        title = models.CharField(max_length=50)
        desc = models.CharField(max_length=200)

Assuming you have imported you models at the top of you views.py file.

   from .models import *

The * imports all the models from the models file.( There are reasons you may or may not want to import all the models in the future.)

In the views.py file

    def processInfo(request):
        print(request.POST["title"]
        if len(str(request.POST["title"])) < 2:
            print("Needs more the 2 characters to submit")
        else:
            print("Meets rule")
            Bio.objects.create(title = request.POST["title"])

The print is there to see if anything is received. You always want to check first if you are not getting an empty string. I use len and other tools to check https://www.w3schools.com/python/ref_func_len.asp There are a few ways on creating and getting data from the django models. https://docs.djangoproject.com/en/3.0/topics/db/queries/

Finally for the function that renders "/" in the views.py file. Once you retrieve the data that you are looking for, return it with the request and html file.
