pagination

问题 I have a redis database where I store the hits of recent random data from mysql. There is plenty of data in redis, and I want to use pagination, or some similar technique, to display the results in parts. I am storing the immediate results in results list, and the full output in final_results . I need each of these "results" in separate urls like /display_items/1 , /display_items/2 , and so on.. If I simply store all the keys in a list (like final_results ), then there is a possibility of an

问题 I am trying to implement pagination which should not show duplicate data in different pages on data insertion or deletion. Basic offset-based approach using skip and limit to paginate data is given on this How to implement pagination for mongodb in node.js using official mongodb client? Offset-based approach has a big flaw: if the results list has changed between calls to the API, the indices would shift and cause an item to be either returned twice or skipped and never returned This problem

问题 I've googled around for this, but part of the problem is that I'm not really sure how to concisely describe my problem. I have two relevant models here: Application and Absence. Application belongsTo Absence, Absence hasMany Application. Here's the schema for Application: CREATE TABLE applications ( id int unsigned AUTO_INCREMENT PRIMARY KEY, user_id int unsigned, absence_id int unsigned ); It's pretty simple. I want to paginate all Absences with an Application from a particular user (I'm

问题 I have set up the Indeed.com xml feed on my site. Their API only allows 25 results per query. How can I paginate the results if there are more than 25? I have not found a satisfactory or thorough enough answer anywhere online. I've searched for weeks on this. Here is what I have in my code: PHP: // Indeed.com API URL parameters $url = 'http://api.indeed.com/ads/apisearch'.'?'; $publisher = 'xxxxxxxxxxxxxxxx'; $q = $query; $location = ''; if (isset($_POST['location'])) { $location = $_POST[

问题 I am reading driver pagination in here. but CQL also support LIMIT in WHERE clause. Wonder what is the difference between these two 回答1: Pagination is how much you of your result you work with at a time. WHERE and LIMIT are about what is in your result. Imagine you request all rows where X < 100. This may refer to 1 million different rows. If the client or the server requested all of this at once it would cause a lot of resource pressure. To avoid this the driver is capable of asking for just

问题 This question already has answers here : Primefaces DataTable + JPA / Hibernate Pagination (2 answers) Closed 11 months ago . Maybe it's a bit weird, but I don't know how to get the pagination of PrimeFaces to my backend. I know there is the showcase and there are multiple answers here but I'm questioning if it really has to be like this. Additionally my project is not structured with DAO and things, which leaves me in the dark. I use a Spring Boot config. The grounding of the whole project

问题 Is it possible to paginate and display number of pages in Coldfusion using only one query? My understanding is you can obviously paginate with one query, but you would need an additional query to create the pages. This is in order to calculate the total number of results. (currentPage - 1) * resultsPerPage = Offset in MySQL query. This logic is sufficient to create next/prev buttons. But in order to know the number of pages, would we not need to know the total number of results using a

问题 I was under the impression with the pagination directive that the {{numPages}} value would be calculated by the directive. It isn't returning anything for me. Is there anything I am missing to get this working properly? I don't want to have to calculate it, if the directive is supposed to be doing this for me. Otherwise paging is working great. <pagination total-items="totalItems" ng-model="currentPage" max-size="maxSize" items-per-page="itemsPerPage" class="pagination-sm" boundary-links=

问题 Is Codeigniter 3 compatible with Bootstrap 4? or is it simply way too outdated to add any uses for bootstrap 4? I've been looking at tutorials online on how to integrate bootstrap to Codeigniter pagination. So far all i've seen is that they mostly changed the $config of the pagination class. For example: //config for bootstrap pagination class integration $config['full_tag_open'] = '<ul class="pagination">'; $config['full_tag_close'] = '</ul>'; $config['first_link'] = false; $config['last
