Flask redirect function not redirecting to the correct page

Question

I have the page app route. This is my python flask code.

from flask import Flask, render_template, flash, redirect
from forms import RegistrationForm, LoginForm

app = Flask(__name__)


@app.route("/")
@app.route("/home", methods=["GET", "POST"])
def home():
   return render_template("home.html")


@app.route("/dashboard", methods=["GET", "POST"])
def dashboard():
    return render_template("dashboard.html")


@app.route("/register", methods=["GET", "POST"])
def register():
    form = RegistrationForm()
    app.logger.debug(form.validate_on_submit())
    if form.validate_on_submit():
        return redirect("dashboard")

    return render_template("registerPage.html", title="Register", forms=form)

When I run it it redirects to http://localhost:5000 when it should redirect to http://localhost:5000/dashboard .
Whats happening?

Answer 1

Add an import for url_for :

from flask import url_for

Then use it in the redirect:

return redirect(url_for("dashboard"))

The url_for function takes the name of a function and constructs the "url for" that function.

You posted a link to your project files on DropBox.

In your template, registerPage.html , you need to change:

 <form method="POST" action="/">

to:

 <form method="POST" action="/register">

If you post to / instead, the register function will never see the posted data and will never redirect the user to the dashboard.
