So I am trying to replicate the code done in Flask lecture video, which still revolves around submitting and inputting a user's name. I think I have done the exact same code as Brian's, but the code throws me an error message.
Here is the code for application.py:
from flask import Flask, flash, jsonify, redirect, render_template, request, session, url_for
from flask_session import Session
from werkzeug.exceptions import default_exceptions, HTTPException, InternalServerError
from werkzeug.security import check_password_hash, generate_password_hash
#Configure application
app = Flask(__name__)
@app.route("/")
def index():
return render_template("index.html")
@app.route("/hello")
def hello():
name = request.args.get("name")
if not name :
return render_template("failure.hmtl")
else:
return render_template("hello.html",name=name)
And the index.html:
{% extends "layout.html" %}
{% block body %}
<form action="/hello">
<input name = "name" type="text">
<input type ="submit">
</form>
{% end block %}
The hello.html:
{% extends "layout.html" %}
{% block body %}
Hello, {{ name }} !
{% end block %}
The failure.html:
{% extends "layout.html" %}
{% block style %}
body
{
color:red;
}
{% endblock %}
{% block body %}
You must provide a name!
{% end block %}
And last is the layout.html:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Hello!</title>
<style>
{% block style %}
{% endblock %}
</style>
</head>
<body>
{% block body %}
{% endblock %}
</body>
</html>
In layout.html, there are those two red circles with cross in the center beside these two lines
{% block style %}
{% endblock %}
They also appear in the lecture video. But when run, his code works, while mine doesn't. The error message looks like this on the IDE:jinja2.exceptions.TemplateSyntaxError: Encountered unknown tag 'end'. Jinja was looking for the following tags: 'endblock'. The innermost block that needs to be closed is 'block'.
and just 500 Internal Server Error on the webpage.
Anybody care to explain why the code doesn't work? I mean it's supposed to be basic and if I can't get this right then I won't have much luck with other more advanced problems. Thanks!
