pagination

问题 I searched a lot about it. All the articles i get include SQLAlchemy and none of them deal with mysql. I am working with flask and i have a database in mysql and i need to display the data in pages. Like 1000 images, per page 10 so 100 pages. In mysql we can do pagination with the help of limit. And the routes can be: @app.route('/images', defaults={'page':1}) @app.route('/images/page/<int:page>') I need to ask is this all that is needed for pagination? or am i forgetting something important

问题 I'm writing my first real scraper and although in general it's been going well, I've hit a wall using Selenium. I can't get it to go to the next page. Below is the head of my code. The output below this is just printing out data in terminal for now and that's all working fine. It just stops scraping at the end of page 1 and shows me my terminal prompt. It never starts on page 2. I would be so grateful if anyone could make a suggestion. I've tried selecting the button at the bottom of the page

问题 I'm using Kaminari for pagination and under a certain situation need the first page to contain only 2 entries while each other to have 6. Thought this was achievable using padding() , but it doesn't seem to work like I'd expect (the documentation doesn't help much either): a = (1..20).to_a b = Kaminari.paginate_array(a).page(1).per(6).padding(2) => [3, 4, 5, 6, 7, 8] Any ideas on how to accomplish this? 回答1: this might help you: a = (1..20).to_a b = Kaminari.paginate_array(a).page(1).per(6)
