How to work with database relationships in Yii's ActiveRecord
Define the relationship in the model class, use hasOne(), hasMany() and other methods to establish one-to-one, one-to-many and many-to-many associations; 2. Access the associated data through attribute syntax to achieve lazy loading, but pay attention to the N 1 query problem; 3. Use with() to actively load to improve performance and support nested relationships; 4. Query the associated data through joinWith() and where(), and conditions can also be added in with(); 5. Saving the associated data requires manual processing, and it is recommended to use transactions to ensure data consistency; 6. Many-to-many relationships are defined through viaTable(), and manually operate the connection table or encapsulation method to manage the association; correctly use indexes, avoid the abuse of lazy loading, and use active loading and transactions reasonably

What is the purpose of the config directory in Yii?
Yii's configuration directory is used to store configuration files that define application behavior and is the central location for management settings. Common configuration files include main.php, web.php, console.php, and params.php, which return an array of configurations used when Yii is started. For example, in web.php, you can configure database connection parameters. To adapt to different environments, files such as main-local.php, web-dev.php are usually used to distinguish development, testing and production environments, and the corresponding configuration is loaded through symbolic links or server variable detection. When the Yii application starts, the configuration file is loaded through the require statement, and sometimes ArrayHelper::merge is used.

How to create a sitemap for a Yii application
Create a SitemapController for dynamically generating sitemaps; 2. Use XML view templates to output XML structures that comply with specifications; 3. Configure routing rules in urlManager to point sitemap.xml to the controller; 4. Add Sitemap links in robots.txt; 5. For large websites, use sitemap index to split multiple files; 6. It is recommended to use cache to reduce database pressure; URLs must be escaped correctly and HTTPS must be maintained, and finally verified through GoogleSearchConsole tests. The entire process needs to ensure that each sitemap file does not exceed 50,000 URLs and the size is less than 50MB.

How to format data for display in Yii
When using Yii2 or Yii3 to format data display, clear separation should be achieved through Formatter components, model getter methods, GridView/DetailView configuration and custom auxiliary tools; 1. Use Yii::$app->formatter to standardize date, currency, Boolean values, etc. and can be set uniformly in the configuration; 2. Define getter methods in the model such as getFormattedPrice to encapsulate reusable formatting logic; 3. Use format options and anonymous functions in the GridView or DetailView to achieve view-level formatting; 4. Use static help classes or custom small

How do I bind form data to a model?
When binding form data to the model in web development, it is recommended to use the framework's own mechanism first, followed by manual binding and attention to field matching, structure nesting and data verification. Specific practices include: 1. Use built-in functions of the framework, such as ModelBinder of ASP.NETCore, @RequestBody of SpringBoot, ModelForm of Django, etc., to automatically complete type conversion and security verification; 2. Get request data in sequence, create model instances, and assign fields one by one (such as assigning req.body to User object in Express); 3. Ensure that the form field name is consistent with the model attributes, handle nested structures, and it is recommended to use DTO to isolate inputs.

How do I render a view from a layout?
In web development, the method of rendering views from a layout is to insert the view content into the layout reservation through the yield mechanism provided by the framework. Use a syntax like @yield to define insertion points in the layout and fill the corresponding blocks in the view file with @extends and @section. For example, in Laravel, the layout file app.blade.php uses @yield('content') to define the content area, while the view file inherits the layout through @extends('layouts.app') and inserts the content with @section('content'). 1. Multiple blocks can be defined by defining multiple @yields (such as header) in the layout
