How do I add arguments to URL in Flask? FOr example, if I wanted to make a URL for one of my pages, like this: “https://worldcache.redcoder.repl.co/some-page?level=2/”
@app.route("/help/<topic>") def help(topic): # Now you have a variable called "topic" that has the same # value as whatever is in the URL. You can use it like a normal # variable and use it for if/else operations and render_template @app.route("/help/<int:topic>") # makes it an integer
How would I set the value of “topic” to a pre-defined Python variable?
I don’t know if you can do that exactly but this would work:
old_topic = "No" @app.route("/help/<topic>") def help(topic): topic = old_topic
I don’t see how that helps in any way.
Or do you mean how do you change what
topic is? All you need to do is go to the URL and Flask will do the rest. So just include a link to
/help/dinosaurs on your website somewhere and then you will have
topic = "dinosaur" for whoever uses that URL. The variable is based on the URL, not the other way around.
To redirect a user to a page with a argument do I do
return redirect("/cache/<topic>") or
The variable “topic” would be pre-defined in both examples
It should be the first one.
The second one. The weird syntax only applies to
It looks like it should work, but right now when I put input in the search field, it redirects me to the login page instead of the desired redirect that I inputed.
@CoderElijah’s method will work, but it’s not what you’re asking for.
from flask import Flask, ..., request ... @app.route("/some-page") def some_page(): level = int(request.args.get("level", default_level)) # Do something with the level variable
And to redirect a user
