Request in Flask from a Form in HTML is returning None Value, What should I Do?
0
I am getting no value on request in flask. It is returning None value.
I have tried changing the method but no use.
The flask code:
@app.route("/login/user/book")
def searchbook():
bookname=request.form.get("search")
return render_template("message.html",heading=bookname ,message=" ")
The webpage:
{% extends "layout.html" %}
{% block heading %}Welcome to BookSarkar{% endblock %}
{% block body %}
<p>Welcome {{ name }}</p>
<form action="{{ url_for('searchbook') }}" method="get" class="form-group">
<div class="form-group">
<input type="text" name="search" class="form-control col-md-6 mt-5 mx-auto" placeholder="Search books">
<p style="text-align:center;">
<button type ="submit" class="btn btn-primary mt-2 mx-auto">Search</button>
</p>
</div>
</form>
<div class="fixed-top m-2">
<a class="btn btn-outline-primary" href="{{ url_for('logout') }}" role="button" style="float:right;">Log out</a>
</div>
{% endblock %}
The message webpage:
{% extends "layout.html" %}
{% block heading %}{{ heading }}{% endblock %}
{% block body %}
{{ message }}
<a class="btn btn-primary" href="{{ url_for('index') }}" role="button">Return to Home Page</a>
{% endblock %}
The layout page has no bugs as all other pages are working fine. I expected the webpage to show the given input but it is showing None

Put a breakpoint atreturn render_template("message.html",heading=bookname ,message=" ")in your flask code and inspect the value of bookname. Is it None or is it populated?

@PeterDannemann I am new to this and dont know how to debug, that is why i am using the return render_template("message.html",heading=bookname ,message=" ") to test whether it is None or populated

Ok just put ‘print(bookname)’ before that line. What does it print when you make a request?

request.form contains values submitted via post or put, while your form uses get. Try using request.args.get("search") instead of request.form.get("search")
