Need to send scores back to LMS from teacher end #168
Description
Hi I am using this gem for my ruby based application ,
And I want to send the scores back to the LMS , but the problem is in my platform a teacher can grade the assignments now I want to send the scores back to the LMS when the teacher view the application from inside LMS,
say @teacher_loogedin.student_1_grade is the grade of the student when teacher is logged in his/her account inside LMS using my LTI provider tool , now I want to send back the score to the LMS and LMS should record the score on behalf of the student 1 , can I do this ?
I have written a function to accomplish this but here score is only the parameter , how to use a student specific parameter like student_email so that the score is reflected for that particular student only.
here is my function, but how to achieve my desired goal ??
def submitscore
@tp = IMS::LTI::ToolProvider.new(@@launch_params[:oauth_consumer_key],
Rails.configuration.lti_settings[@@launch_params[:oauth_consumer_key]],
@@launch_params)
# add extension
@tp.extend IMS::LTI::Extensions::OutcomeData::ToolProvider
if !@tp.outcome_service?
@message = "This tool wasn't lunched as an outcome service"
puts "This tool wasn't lunched as an outcome service"
render(:launch_error)
end
res = @tp.post_extended_replace_result!(score: params[:result]) # here I want to pass a parameter of student email such that the corresponding student can be graded
if res.success?
puts "Score Submitted"
else
puts "Error during score submission"
end
redirect_to @@launch_params[:launch_presentation_return_url]
end
my problem is also similar to this but I need to solve this using this gem , please help me
