How can I use values passed to a controller to string inside
Hi again! Consider the codes below:
def new(conn, %{"invoice" => invoice_params}) do
variable = "Hello *string here* Hooray *string2 here* day"
end
My goal is that parameters passed to that controller can be used as a string.
I tried #{invoice_params.payorcode} but it’s not working

When you have Phoenix controller, all your data send as JSON in body has keys in string format.
To prepare your code, you should use:
def new(conn, %{"invoice" => invoice_params}) do
variable = "Hello #{invoice_params["payorcode"]} Hooray *string2 here* day"
end
With map["key"] you can access parameters. Remember this will return nil when not found data in map (no data with selected key), and #{...} will replace it with "" - empty string.
