Get started quickly and use the Ruoyi code generator
to directly save a set of curd
1. Start the Ruoyi framework
Skip this first,
directly refer to the official document
http://doc.ruoyi.vip/ruoyi/document/hjbs.html
2. Use the code generator
Refer to the official document to write
http://doc.ruoyi.vip/ruoyi/document/htsc.html#%E4%BB%A3%E7%A0%81%E7%94%9F%E6%88%90
1 Import the sample table
First create a new table in your backend database
for an example
drop table if exists sys_student;
create table sys_student (
student_id int(11) auto_increment comment '编号',
student_name varchar(30) default '' comment '学生名称',
student_age int(3) default null comment '年龄',
student_hobby varchar(30) default '' comment '爱好（0代码 1音乐 2电影）',
student_sex char(1) default '0' comment '性别（0男 1女 2未知）',
student_status char(1) default '0' comment '状态（0正常 1停用）',
student_birthday datetime comment '生日',
primary key (student_id)
) engine=innodb auto_increment=1 comment = '学生信息表';
2 Use the built-in code to generate a zip file
2.1 Illegal mix of collations error resolution

there is a pit
If an error is reported when clicking the import table
If the table cannot be imported according to the system code generation: Illegal mix of collations...
It is the table information_schema.tables that comes with mysql, which is associated with the tables of the Ruoyi system.
The information_schema is sorted by utf8_general_ci encoding. If you build a database, utf8_unicode_ci is selected by default.
Therefore, rebuild the Ruoyi database and use utf8_general_ci encoding.
problem solved.
Three Paste the contents of the zip file into the corresponding module
3.1 Paste background code
1
controller pasted into
The red circle is the project package name
and code package name
, but we found that the controller package name of the project
is not consistent with the controller package name of the generated code
The name of the project package is used here.
At this time, change the name of the controller package that generates the code to the package name of the project controller.
2 Paste the rest of the generated code
into
Discovery
This package name is the same as the package name of the generated code
without any changes
In this way, the background code is pasted
3.2 Paste the foreground code
Just paste it directly
3.3 Run menu sql statement
Open the database
, run the sql file,
and directly run the generated sql
4. Restart the frontend and backend
First maven clean to clear the compiled target
and then restart
Front-end ctrl+s to save
final effect
Summarize
Tip: Here is a summary of the article:
For example: the above is what I will talk about today. This article only briefly introduces the use of pandas, and pandas provides a large number of functions and methods that allow us to process data quickly and easily.
