is used to record the number of user votes corresponding to articles or comments, in addition, we write a data entry with id 1 by default for demonstration. The votes_ip table is used to record the IP address of each user vote. The program determines whether the vote is valid based on the user IP address. CREATE TABLE IF NOT EXISTS `votes` ( `id` int(10) NOT NULL AUTO_INCREMENT, `likes` int(10) NOT NULL DEFAULT '0', `unlikes` int(10) NOT NULL DE

Describe In this section, we will continue to discuss the conditional operator $type in MongoDB. The $type operator retrieves the matching data type in the collection based on the Bson type and returns the result. The types that can be used in MongoDB are shown in the following table: type numeric notes Double 1 String 2 Object 3 Array 4 Binary Data 5 Undefined 6 is obsolete. Object ID 7 Boolean 8 Date 9 Null Regular Expression JavaScript Symbol-JavaScript (with scope) 1 5 32-bit Timestamp 64-bi

A common thumbs-up function is to count the accumulated number of times. The database field is very simple, just an unsignedint. The question is how to record the likes. I don't know if I can use a string to record the id of the person who likes? For example, quot;, 169,4214 quot; indicates that users with four different IDs click like .... A common thumbs-up function is to count the accumulated number of

When we browse the Web, we want to agree or disagree with the content of the page, such as articles, comments, and then click on the "Top" and "step" in the page to vote. and the entire interaction process, developers can use Ajax asynchronous to achieve, thereby improving the user experience. We're going to run the MySQL data table for the entire instance, with two tables in the instance, a votes table to record the number of user votes for the corresponding article or comment, and we write a

recommendations Content-based recommendation is the most widely used recommendation mechanism at the beginning of the recommendation engine, and its core idea is to discover the relevance of items or content based on the metadata of the recommended items or content, and then recommend to the user similar items according to the user's previous preferences. Figure 3 shows the rationale for content-based recommendations. Figure 3. Fundamentals of Content-based recommendation mechanism Figure 3 sho
