Yii2 initial experience and yii2 initial experience
Yii1.1 was so uncomfortable, and yii2's maturity grew up day by day, so we made up a prototype phase of a small project and tried to use yii2.
With a hand-written experience, let's put it simply from the perspective of Yii1's skilled workers looking at Yii2. (It may be added after this article at any time in the future)
- The default template uses bootstrap, which is beautiful.
- The basic and advanced versions of the config file are not the same. In basic, there is web. php, and the latter does not.
- Set to Chinese display: In config/web. php, add a line 'language '=> 'zh-cn '. Then the Home is changedHomepage, Powered by Yii Framework becomesTechnical support Yii framework.
- When gii is used to generate a model, I checked Use Table Prefix. The generated model returns {% menu} in the tableName () function }}. If this option is not selected, the full name of the table name is returned, for example, ssn_menu.
- Many functions are added to models/user. php, which is much more convenient.
- [...] Is used everywhere in models and controllers to replace array.
- What is the URL of LibCrudController? R = lib-crud
- Start to customize the user login part .. Http://www.yiichina.com/tutorial/332
- Start CRUD (from 20: 20)
- User: find ()-> all () instead of User: model ()-> findAll ()
- To reference a User in _ form. php, you must first declare the use app \ models \ User;
- To reference ArrayHelper in a View File, you must first declare use yii \ helpers \ ArrayHelper;
- In Yii v1.1, three rows are required for data entry. Here, only one row is required:
<? = $ Form-> field ($ model, 'name1')-> textInput (['maxlength' => true])?>
- The CRUD interface generated by gii is much more atmospheric and beautiful, and the prompt information is automatically Chinese (this should be the credit of GridView)
- User: findOne ($ user_id); is different from the following. This returns a record, and the following is unknown.
$ User = User: find ()-> where (['id' => $ id]);
- Add my.css: First add my.css to web/CSS, and then add it to assets/AppAsset. php.
Public $ css = ['css/site.css ',
'Css/my.css ',];
- Place the js file: $ this-> registerJsFile ("js/start. js"); -- When jquery is dependent, this is obviously unavailable and the system prompts that $ is not found.
- Https://segmentfault.com/a/1190000003742452 is very clear here. Several solutions. The modified assets/AppAsset. php solution has been called. One of the key points is (see the black text): AppAsset: addScript ($ this ,'@ Web/Js/start. js ');
- There is a cool debug-toolbar button in the lower right of the page. A horizontal status bar will pop up when you click it.
- Index. php in the address bar? R = site/index will change to index. php? R = site % 2 Findex
