Dynamically "attach" a form in Rails 4 -


Assume that I have a post model that has several comments where all the posts were shown In the post # index page, I want to allow users to add their comments for specific posts (I know that it does not matter much, this is a common idea) .

The method of "brute force" will have to attach a form to each post element, but this is bad stinking. I'm sure there are better options which I can not think of now Therefore, appreciate the help, therefore.

Thanks, Roy

(P.S. - A good example would be FB page in which a user can comment on each post in the timeline, and I think having a form for each one Is not due to ...)

You can find JS & amp; Ajax, like this: 

  # config / routes.rb Resources: Post resources are: Comments # app / assets / javascript / application.js $ (document) expired .on (click " "," A.new_comment ", function () {# id = $ (this) .attr (" id "); $ .ajax ({url: $ (this) .attr (" href "); success: function ( Data) {$ ("#" + ID) .append (data);}});}); #app / idea / post / index.html. ARB & lt;% @ posts.each do | Post | & Gt%; & Lt;% = post.title% & gt; & Lt;% = link_to "Add comment", new_post_comment_path (post.id), category: "new_comment", id: post.id% & gt; & Lt;% end% & gt; #Apps/Controller/Content_Controller Rb def new @ comment = comment.nup_report_to do it Format | Format.html {Layer Render:! Request.xhr? } End End

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. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
