rating

问题 I run a calendar photo contest that uses a 5-star rating system which ranks the images according to their average rating. However, I would like to factor in the total number of votes a photo receives to get a more accurate ranking. For example, I do not want an image with 1 5-star vote (Avg rating: 5) getting ranked above an image with 10 5-star votes and 1 4-star vote (Avg rating: 4.9). I know this topic has been raised before, but I can't seem to find a straightforward answer to apply to my

问题 I've seen posts here on Stackoverflow that describe how to allow users to be directed to apps on the app store. Is there a way to link directly to the rating and comments form in the App Store? 回答1: Answers here are outdated. This works on my end (Xcode 5 - iOS 7 - works only on Device, not simulator !): itms-apps://itunes.apple.com/app/idYOUR_APP_ID For versions lower than iOS 7 use the old one: itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple

问题 I've a simple rating system setup in a blog model. I use a custom method to increase rating, which is integer in blog db. def increase @post = Post.find(params[:id]).increment!(:rating) if logged_in? current_user.increment!(:votes) end flash[:notice] = "Thanks for rating" redirect_to posts_url end Right now, I can vote as many times as I want, which is of course a recipe for disaster. Users can vote multiple times and drive the count way way up. How do I make it so that the vote submit button

问题 I am trying to make a rating system, very similar to Youtube's thumbs Up/Down. Actually, I was hoping to achieve exactly the same. But from what I gather from here: http://code.google.com/apis/youtube/2.0/developers_guide_protocol.html#Ratings Youtube uses an API to take care of all the Ratings. So I am looking for info and help on how can I set up the same system YT has. I basically want to have a Like/Dislike function for every page, which is liked to a specific object on that page - just

问题 Is there a way to call to the star rating of a specific product on a custom page, at custom locations? In other words, can I add a star rating of a specific tshirt to appear under a picture of the tshirt on my homepage, for example? I imagine I need to add some sort of php to my editor and then call it by some sort of html. I saw this answered thread, in which, one of the answers seems to have helped people, however, it only gives you the necessary php, so I don't know how to actually put

问题 I'm currently taking the online standford class on databases, If you could help me solve this sql problem I would greatly appreciate it. Sorry I'm a complete noob. Table Movie: mID | title | year | director Table Rating rID | mID | stars | ratingDate Table Reviewer rID | name For all pairs of reviewers such that both reviewers gave a rating to the same movie, return the names of both reviewers. Eliminate duplicates, don't pair reviewers with themselves, and include each pair only once. For

问题 I was thinking of implementing a thumbs system, but mine would require a registration thus ruling out the possibility of people voting more than once unless they create a new account to do so. So I was wondering about Urban Dictionary's thumb system. How does it work? I would imagine that my IP would be stored in a database, so people would not be able to vote more than once however IPs do change pretty often and especially when you're on an iPhone. Probably a combination of cookies and IP

问题 I see many apps saying that "if you give 5 star rating to our app you will receive 1000 coins." The user can use these coins in the downloaded app. I want to implement the same feature. How can we determine who has given 5 star rating to our iPhone app programmatically so that we can give them coins immediately after they have given the rating? 回答1: There's no official API to get reviews in iTunes, though you can get them in iTunes Connect and there are apps that scrape them (though they can

问题 Unfortunately I need to ask someone that has found out how to do this because me and a friend could not achieve this in 8 hours of trying. What we want to do: Just get the ratings of any given YouTube video (via its ID) and post these in an echo. We had this before YouTube switched to the API V3 and are now unable to get this to work in the new API. How it worked in V2: We created a function that basically used the PHP API to set an array like this: $rating[] = $videoEntry->getVideoRatingInfo
