Tumblr like button not working after infinite scroll ajax recall

由 ≯℡__Kan透↙ 提交于 2019-12-30 05:26:08
问题 There are a few similar posts but they are quite out of date and Tumblr has updated the like part of the API not too long ago as far as I'm aware. Creating a like button is as simple as {LikeButton} and this works great, but after the ajax recalls to get more posts from what would be the next page, the like button no longer works. I have had a look at the documentation and it states that I need to implement one of the following, I was wondering if anyone could point me in the right direction?

(with the problem that he can remove the cookie and vote x999 times) or I store his IP in database? 回答1: The solution has three parts: use a cookie to prevent double votes store all vote events in the database (ip, user agent, poll/article id, vote) implement an algorithm which will run every 24h to delete the double votes which escaped from #1. The algo

问题 I installed the acts_as_votable gem, it works in the console like it should (like it says in the documentation). So my question is how to set up a form for upvote and downvote buttons? or can they simply be links? here is the documentation: github.com/ryanto/acts_as_votable/blob/master/README.markdown I have a user and a picture model; the user is supposed to be able to like the picture. code from the picture view, where the buttons should be: <% for picture in @pictures %> <p> <%= image_tag

Rails Acts_as_votable Gem Like/Unlike Buttons with Ajax

由 戏子无情 提交于 2019-12-06 05:31:14
问题 I'm new to Ruby On Rails, I used the acts_as_votable gem to create Like and Unlike Buttons to make Users like and unlike Posts but I can't make them change from Like to Unlike (and viceversa) and update the counter each time they click without refreshing the page. I tried following other kind-of-similar answers but I had no luck. Without the messy changes I tried to do to implement Ajax my code looked like this: Post Model acts_as_votable and User Model acts_as voter Posts Controller has def
