FeedbackVotes collection

This feature may use a new collection called FeedbackVotes. Each Feedback Vote document will contain the following fields:

• feedbackId - string - the ID of the Feedback document
• userId - string - the ID of the user
• vote - integer - the numeric vote for the user (allowed values: 1 and -1)

Collection helper(s)

The following collection helper will be attached to the Feedback collection:

• sumOfVotes() - adds all vote integers together, returns the sum of all votes as an integer

Server method(s)

The following method(s) will be defined on the server:

• submitVote(vote) - takes an integer as an argument, checks whether user has already voted, either updates existing or adds new user vote

Publication(s)

The following publication(s) will be useful:

• getAllVotesForSingleFeedback (feedbackId) - returns a database cursor for the following query:

FeedbackVotes.find({feedbackId: feedbackId});

Template-level subscription(s)

Each feedback template will subscribe to the getAllVotesForSingleFeedback publication. This will ensure that only votes for displayed feedback are returned.

Definition of done

• Up and downvote arrows appear on each feedback item
• The sum of all up/downvotes displays between up and down arrows
  • Display of sum of votes is visually prominent
• Display of voting arrows is visually prominent
  • Arrows are large enough for easy interaction in touch device
• Up/down arrows change visual appearance to indicate existing user vote
  • Color change
• Mouse cursor changes to 'hand pointer' when hovering over vote arrow, to indicate the user can interact with arrow
• Clicking on a vote a second time deletes user vote.
  • E.g. clicking up and up again 'resets' the user vote
• Any given user can vote only once for a given feedback item
• Anonymous votes are not allowed

Optional

• Sum of votes displays to anonymous visitors
• When anonymous visitor clicks vote arrow, an alert (sAlert) displays instructing the user to 'log in to vote'
