Adding a query string to a redirection

That’s because redirect works with any path/url and get params are just a part of them:

        Routes.user_path(
          conn,
          :show_user,
          some_param,
          other_param,
          foo: "bar"
        )

Actually the value of my parameter is a boolean, so I wanted to convert to 1 or 0, like:

active: is_active ? 1 : 0

What is the reason that Elixir doesn’t have a ternary operator? How would you write that?

if(is_active, do: 1, else: 0)

The above is hardly longer than something akin to a ternary operator, but using the default elixir keyword syntax. Meaning nothing had to be created to support it.

Thank you!

By the way, do you think it’s safe to insert user input in a query string value (comment below)?

redirect(conn,
      to:
        Routes.user_path(
          conn,
          :show_user,
          some_param,
          other_param,
          foo: some_user_input    # <- is this safe?
        )
    )

active: is_active && 1 || 0

This is not a recommended pattern, and it can fail in a couple of surprising ways (specifically if the 1 in the above example where nil or false because it interprets it as active: (is_active && 1) || 0), but it’s the bash’ism style, that works in Elixir too. ^.^;
