### Dynamic Menu and Breadcrumb Generation

Source: https://github.com/xingxingzaixian/django-vue3.2-online-exam/blob/master/UPDATE.md

This entry describes the implementation of dynamic menu generation based on user roles or permissions, and the creation of dynamic breadcrumbs for improved navigation within the application. It also mentions exporting LESS variables to JavaScript.

```Vue.js
// Conceptual example for dynamic menu generation
<template>
  <nav>
    <ul v-for="menuItem in dynamicMenu" :key="menuItem.id">
      <li>{{ menuItem.name }}</li>
    </ul>
  </nav>
</template>

<script>
import { computed } from 'vue';
import menuData from './menuConfig'; // Assume this holds menu structure

export default {
  setup() {
    // Logic to determine which menu items to show based on user permissions
    const dynamicMenu = computed(() => {
      // Example: Filter menuData based on user role
      return menuData.filter(item => item.roles.includes('admin'));
    });

    return { dynamicMenu };
  }
}
</script>

// Conceptual example for dynamic breadcrumb generation
<template>
  <el-breadcrumb separator=">">
    <el-breadcrumb-item v-for="(item, index) in breadcrumbs" :key="index" :to="{ path: item.path }">
      {{ item.meta.title }}
    </el-breadcrumb-item>
  </el-breadcrumb>
</template>

<script>
import { ref, watch } from 'vue';
import { useRoute } from 'vue-router';

export default {
  setup() {
    const route = useRoute();
    const breadcrumbs = ref([]);

    const generateBreadcrumbs = (currentRoute) => {
      const matched = currentRoute.matched.filter(item => item.meta && item.meta.title);
      breadcrumbs.value = matched.map(item => ({
        path: item.path,
        meta: item.meta
      }));
    };

    watch(() => route.fullPath, (newPath) => {
      generateBreadcrumbs(route);
    }, { immediate: true });

    return { breadcrumbs };
  }
}
</script>

// Example of exporting LESS variables to JS (conceptual)
// styles.less
@primary-color: #ff0000;

// main.js or a dedicated file
import './styles.less';
import { get } from 'lodash'; // Assuming lodash is used for deep access

// Accessing the variable might require a build tool setup that injects variables
// or a specific pattern like CSS Custom Properties if using modern CSS.
// A common approach is to use a plugin that extracts variables.
// For simplicity, let's assume a mechanism exists to access them.
// const primaryColor = get(window.__LESS_VARIABLES__, 'primary-color');
// console.log(primaryColor); // Output: #ff0000
```

### Custom User Model

Source: https://github.com/xingxingzaixian/django-vue3.2-online-exam/blob/master/backend/README.md

Definition of a custom user model inheriting from Django's AbstractUser, including fields like uid, nickname, and telephone.

```python
from django.contrib.auth.models import AbstractUser
from django.db import models
from uuid import uuid4


# Create your models here.

class UserInfo(AbstractUser):
    uid = models.CharField(max_length=36, default=uuid4, primary_key=True)
    nickname = models.CharField(max_length=32, verbose_name='昵称')
    telephone = models.CharField(max_length=11, blank=True, null=True, unique=True, verbose_name='手机号码')
    create_time = models.DateTimeField(auto_now_add=True, verbose_name='创建时间')

    class Meta:
        db_table = 'tbl_user'
```

### Form Validation Implementation

Source: https://github.com/xingxingzaixian/django-vue3.2-online-exam/blob/master/UPDATE.md

This entry indicates the addition of form validation logic to the project, likely to ensure data integrity and improve user experience by providing immediate feedback on input errors.

```JavaScript
// Conceptual example using a validation library like VeeValidate or built-in browser validation
// Example using HTML5 validation attributes:
<template>
  <form @submit.prevent="submitForm">
    <input type="text" v-model="formData.name" required minlength="3">
    <span v-if="!formData.name">Name is required.</span>
    <button type="submit">Submit</button>
  </form>
</template>

<script>
export default {
  data() {
    return {
      formData: {
        name: ''
      }
    };
  },
  methods: {
    submitForm() {
      // Form submission logic if validation passes
      console.log('Form submitted:', this.formData);
    }
  }
}
</script>

// Example using a Vue validation plugin (e.g., VeeValidate):
// <template>
//   <VForm @submit="onSubmit">
//     <Field name="email" rules="required|email" v-model="email" />
//     <ErrorMessage name="email" />
//     <button type="submit">Submit</button>
//   </VForm>
// </template>
// 
// <script>
// import { Field, Form as VForm, ErrorMessage } from 'vee-validate';
// import * as yup from 'yup';
// 
// export default {
//   components: { Field, VForm, ErrorMessage },
//   setup() {
//     const schema = yup.object({
//       email: yup.string().required().email(),
//     });
// 
//     const onSubmit = (values) => {
//       console.log('Form submitted:', values);
//     };
// 
//     return {
//       schema,
//       onSubmit
//     };
//   }
// }
// </script>
```

### Django REST Framework Settings for JWT

Source: https://github.com/xingxingzaixian/django-vue3.2-online-exam/blob/master/backend/README.md

Configures Django REST Framework to use the custom JWT authentication class by default and sets datetime formats.

```django
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'utils.authentications.JwtAuthentication'
    ],
    'DATETIME_FORMAT': '%Y-%m-%d %H:%M:%S',
    'DATETIME_INPUT_FORMATS': '%Y-%m-%d %H:%M:%S'
}

```

### Frontend API Endpoint Address Modification

Source: https://github.com/xingxingzaixian/django-vue3.2-online-exam/blob/master/UPDATE.md

This entry indicates a change in the configuration of frontend API endpoint addresses. This is often done to point to a different backend environment (e.g., development, staging, production) or to update the API base URL.

```JavaScript
// Conceptual example of modifying API endpoint configuration
// Assuming an api.js or config.js file is used:

// Old configuration (example):
// const API_BASE_URL = 'http://localhost:8000/api';

// New configuration (example):
const API_BASE_URL = 'https://api.yourdomain.com/v1';

// Or if using environment variables:
// const API_BASE_URL = process.env.VUE_APP_API_URL || 'http://localhost:8000/api';

// The change would involve updating the value of API_BASE_URL or the environment variable.

// Example usage in a service:
// import axios from 'axios';
// const apiClient = axios.create({ baseURL: API_BASE_URL });
// 
// export default {
//   getExams() {
//     return apiClient.get('/exams');
//   }
// }
```
