2,432 PointsHaving trouble passing arguments to the update_signature() method. Challenge Task 5 of 6 -Building Web Apps w/ Sinatra
Can seem to figure out what arguments need to get passed into the update_signature() method within my put request. Any help would be appreciated. Thanks! #line 27
<p>Please enter your name below.</p>
<form method="post" action ="/signatures/<%=@index%>">
<input type="hidden" name="_method" value="put">
<input type="text" name="signature" value="<%= @signature %>">
<input type="submit">
</form>
require "sinatra"
def load_signature(index)
# Code omitted for brevity
end
# Updates the line at the given index and re-saves the file.
def update_signature(index, signature)
lines = File.readlines("signatures.txt")
index = index.to_i
lines[index] = signature
File.open("signatures.txt", "w") do |file|
file.puts lines
end
end
get "/:index/edit" do
# Code omitted for brevity
end
get "/signatures/new" do
# Code omitted for brevity
end
# ROUTE FOR PUT REQUESTS GOES HERE
put "/signatures/0" do
update_signature(params[@index], params["signature"])
end

Treehouse TeacherYou're close, but your put "/signatures/0"
should be renamed to use an :index
URL parameter in place of the 0
. Then you should access params[:index]
, not params[@index]
.
