Get variables parsed from Flask URL

Question

Suppose I have a simple route with a variable part:

@app.route(\'/post/\')
def show_post(post_id):
    return \'Post %d\' % post_id


        

Answer 1

Use request.view_args:

@app.context_processor
def provide_foo():
    if "post_id" in request.view_args:
        post_id = request.view_args["post_id"]
        return {"bar": some_function(post_id)}
