推荐答案

答案很明显.他们需要登录才能进行评分，并且您可以根据其ID存储他们的评分，这样就知道他们已经评分了.

The answer is obvious. They need to be logged in to rate, and you store their rating against their id, so you know they have rated already.

ya dats k ..我们将存储评分. ...但是如果用户再次看到他的最早评级n想要更改...但是此操作没有完成...该评级一次是最终的....如何???

ya dats k..we''l store the rating....but if the user again he see''s his earliest rating n want to change...But this shud not be done...the rating once is final....how???

一旦您可以找到谁进行了评分，则完全由您控制.您可以编写代码以覆盖旧的评分，也可以检测到它，而不会让用户再次评分.这确实非常容易，并且完全取决于您编写代码以使其按需工作.

Once you can detect who made a rating, it''s entirely in your control what happens. You can write code that overwrites the old rating, or detects it and does not let the user rate again. That''s really pretty easy, and something that depends entirely on you writing the code to work as you want it to.
