ruby on rails - Rank posts by comments added today -


I have two models: Posts and comments I want to rank a post by # of comments posted today. So far, I have given it a place in the number of comments and I am not sure how to add today's part.

These are the post controllers: 

  @posts = post.order ('posts.comments_count desc')   
 I have Have tried  
  @ posts = post.dr ('posts.comments_count desc'). Where ("created_at> =?", Time.son.new.bizening_off_de)   
 but nothing returned.   
 
 
 Your second query will  
 
 
  
 
 
 
 
 
 
 
 
 
> @posts = post. Selection (counting as 'post. *, Count (comment.id)') .Jom ((comments) where ('comments.created_at> gt; =,' time.jon.nough.bizing_off_de) .group ( 'Posts.id') .order ('count_comments desc')   
 If you want to include all the posts that do not have any comments today, then you have a  left-hand participle  will be required:  
  @posts = post.select ('post. *, Count_comments' as count (comment id) .joins ("comments.post_id = Comments and comments on posts.id. Created_at & gt; = '# Time.zone.now.beginning_of_day}' ') .group (' posts.id ') .order (' count_comments desc ')

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon.
