# 查询解析器
|
||||
|
||||
## 排序规则
|
||||
|
||||
排序操作本质上是`SQL`里面的`Order By`条件。
|
||||
|
||||
| 序列 | 示例 | 备注 |
|
||||
|----|--------------------|--------------|
|
||||
| 升序 | `["type"]` | |
|
||||
| 降序 | `["-create_time"]` | 字段名前加`-`是为降序 |
|
||||
|
||||
## 过滤规则
|
||||
|
||||
过滤器操作本质上是`SQL`里面的`WHERE`条件。
|
||||
|
||||
过滤器的规则，遵循了Python的ORM的规则，比如：
|
||||
|
||||
- [Tortoise ORM Filtering](https://tortoise.github.io/query.html#filtering)。
|
||||
- [Django Field lookups](https://docs.djangoproject.com/en/4.2/ref/models/querysets/#field-lookups)
|
||||
|
||||
如果只是普通的查询，只需要传递`字段名`即可，但是如果需要一些特殊的查询，那么就需要加入`操作符`了。
|
||||
|
||||
特殊查询的语法规则其实很简单，就是使用双下划线`__`分割字段名和操作符：
|
||||
|
||||
```text
|
||||
{字段名}__{查找类型} : {值}
|
||||
{字段名}.{JSON字段名}__{查找类型} : {值}
|
||||
```
|
||||
|
||||
| 查找类型 | 示例 | SQL | 备注 |
|
||||
|-------------|---------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------|
|
||||
| not | `{"name__not" : "tom"}` | `WHERE NOT ("name" = "tom")` | |
|
||||
| in | `{"name__in" : "[\"tom\", \"jimmy\"]"}` | `WHERE name IN ("tom", "jimmy")` | |
|
||||
| not_in | `{"name__not_in" : "[\"tom\", \"jimmy\"]"}` | `WHERE name NOT IN ("tom", "jimmy")` | |
|
||||

# 命名法转换
|
||||
|
||||
- camelCase 驼峰式命名法（大驼峰）
|
||||
- PascalCase 帕斯卡命名法（小驼峰）
|
||||
- snake_case 蛇形命名法
|
||||
- kebab-case 烤肉串命名法
|
||||
|
||||
## camelCase 驼峰式命名法（大驼峰）
|
||||
|
||||
驼峰式命名法（Camel case）是一种不使用空格，将多个单词连起来形成一个标识符的命名方式，其中每个单词的首字母（除了第一个单词，如果使用小驼峰式命名法）都大写，就像骆驼的驼峰一样。
|
||||
|
||||
驼峰式命名法分为两种：首字母小写的“小驼峰式”（lowerCamelCase）和首字母大写的“大驼峰式”（UpperCamelCase，也称为帕斯卡命名法PascalCase）。
|
||||
|
||||
- **小驼峰式(lowerCamelCase)**: 第一个单词的首字母小写，后续单词的首字母大写。例如：`myVariableName`。
|
||||
- **大驼峰式(UpperCamelCase)**: 每个单词的首字母都大写。例如：MyVariableName，也称为帕斯卡命名法（PascalCase）。
|
||||
|
||||
在 JavaScript、Java和C#中，驼峰式大小写常用于变量和函数的命名。
|
||||
|
||||
```javascript
|
||||
let firstName = "John";
|
||||
let lastName = "Doe";
|
||||
|
||||
function printFullName(firstName, lastName) {
|
||||
let fullName = firstName + " " + lastName;
|
||||
console.log(fullName);
|
||||
}
|
||||
```
|
||||
|
||||
## PascalCase 帕斯卡命名法（小驼峰）
|
||||
|
||||
`PascalCase`，也称为`UpperCamelCase`，是一种在编程中使用的命名约定。它要求每个单词（包括第一个单词）的首字母都大写，并且单词之间没有空格或分隔符（如
|
||||
`_`）。例如，`ThisIsPascalCase`，`MyClassName` 都是使用PascalCase的例子。
|
||||
|
||||
PascalCase 通常用于在 C#、Java 和TypeScript等语言中命名类、接口和其他类型。
|
||||
|
||||
```typescript
|
||||
class Person {
|
||||
firstName: string;
|
||||
lastName: string;
|
||||
|
||||
constructor(firstName: string, lastName: string) {
|
||||
this.firstName = firstName;
|
||||
this.lastName = lastName;
|
||||
}
|
||||
|
||||
printFullName(): void {
|
||||
let fullName = this.firstName + " " + this.lastName;
|
||||
console.log(fullName);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## snake_case 蛇形命名法
|
||||
|
||||
蛇形命名法是一种使用下划线 (`_`) 分隔单词的命名方式。之所以叫蛇形命名法，是因为"`snake_case`"的
|
||||
下划线的形状类似于蛇腹上的鳞片。蛇形命名法通常用于Python、Ruby 和JavaScript等语言的变量名和函数名。
|
||||
|
||||
```python
|
||||
first_name = "John"
|
||||
last_name = "Doe"
|
||||
|
||||
def print_full_name(first_name, last_name):
|
||||
full_name = first_name + " " + last_name
|
||||
print(full_name)
|
||||
```
|
||||
|
||||
## kebab-case 烤肉串命名法
|
||||
|
||||
`kebab-case（烤肉串命名法）`，也被称作 `kebab case`、`dash-case（破折号式）`、`hyphen-case（连字符式）`、`lisp-case（Lisp 式）`。
|
||||
|
||||
kebab-case 要求短语内的各个单词或缩写之间以`-`（连字符）做间隔。 例如："`kebab-case`"。
|
||||
|
||||
短横线命名法通常用于 URL、文件名和 HTML/CSS 类名。
|
||||
|
||||
```html
|
||||
|
||||
<div class="user-profile">
|
||||
<p>This is a user profile.</p>
|
||||
</div>
|
||||
```
