How can I create a Dynamic Route in Flask from an existing View?-CodePudding

I am somewhat stuck trying to figure out how to configure a route in Flask properly. I'll try and give some contextual information first:

My web app allows Users to join Clubs. A user can join 1 or many clubs.

Each Club has a dashboard page, and I am serving that to the user via Blueprint:

Route:

@club_bp.route("/clubdashboard/<int:Club_id>", methods=["GET"])
@login_required
def clubdashboard(Club_id):
    """Logged-in User Club Dashboard."""
    selectedClub=Club.query.get(Club_id)
    
    return render_template(
        "clubdashboard.html",
        title="Club Dashboard",
        current_user=current_user,
        clubname=selectedClub.name,
        members = selectedClub.members
    )

Jinja2 Template Snippet:

          <div  aria-labelledby="navbarDropdown">
            {% for club in current_user.users %}
            <a  href="{{ url_for('club_bp.clubdashboard', Club_id=club.id) }}">{{ club.name }}</a>
            {% endfor %}
          </div>

The currentuser.users property contains a List of id values for clubs the user is a member of (the .users property is crappy naming on my part, it's on my todo list to fix it.)

The Jinja snippet creates a dropdown menu in the navbar to allow the clubdashboard route to serve an individual dashboard per club.

What I am looking to do is within the Club Dashboard view have a link called "Customize" that, in future, can do a bunch of things (not exactly relevant just yet), but first i'd like to just figure out how to serve the page properly.

For any individual club dashboard I get a URL such as:

http://127.0.0.1:5000/clubdashboard/763074009760399361

What i'd like is simply to serve a URL like this:

http://127.0.0.1:5000/clubdashboard/763074009760399361/customize

But I can't seem to figure out how to do it. Any ideas on where to start would be greatly appreciated.

CodePudding user response：

Simply add the route:

@club_bp.route("/clubdashboard/<int:club_id>/customize", methods=["GET"])
@login_required
def club_customize(club_id):
    """Customize whatever is specific to your club"""
    return "TODO: Actually make it work"

And then you can route to it with a simple url_for("club_bp.club_customize", club_id=club.id)

CodePudding user response：

I've managed to get it working how i'd like. Not sure if it's exactly the best way to do it so happy to be corrected still, but here goes:

In my existing Dashboard route, I took the club ID value and stored it in a user session variable:


    @club_bp.route("/clubdashboard/<int:Club_id>", methods=["GET"])
    @login_required
    def clubdashboard(Club_id):
        """Logged-in User Club Dashboard."""
        selectedClub=Club.query.get(Club_id)
        session['selectedclubid'] = selectedClub.id
    
        return render_template(
            "clubdashboard.html",
            title="Club Dashboard",
            current_user=current_user,
            clubname=selectedClub.name,
            members = selectedClub.members
        )

I then pass the session variable into the Club Rules (Customise) route from the Jinja template:

<a  href="{{ url_for('club_bp.rules', Club_id=session['selectedclubid']) }}">Club Rules</a>

Route:

    @club_bp.route("/clubdashboard/<int:Club_id>/rules", methods=["GET"])
    @login_required
    def rules(Club_id):
        """Logged-in User Club Dashboard."""
        selectedClub=Club.query.get(Club_id)
        
        return render_template(
            "clubrules.html",
            title="Club Rules",
            current_user=current_user,
            clubname=selectedClub.name,
            members = selectedClub.members
        )

This route performs a query for the relevant data and displays. I might have been overthinking the issue.
