Yii2: Tips & Tricks

[Ragazzo (Godlike Man)]

yes, this one. It would be handy since it has favorites, tags and other things.

[thimt8-yii]

Very, very good initiative!

Congratulations.

I’m hoping that a repository of tips and complete and comprehensive code is created.

[samdark (Alexander Makarov)]

I’m planning to collect these and write a cookbook similar to the one for 1.1. This time it will be opensourced.

[komodo (J Theill)]

Nice job Orey and thanks for sharing this!

Maybe the Yii-team can create a git repository (yii2-cookbook) where people can submit PR´s with small recipes/examples like Orey have done here. The repository could compose primarily of files with markdown syntax (*.md). And then on each commit, the cook book is generated and published to the website (just as the documentation).

What do you think?

[samdark (Alexander Makarov)]

Done: https://github.com/samdark/yii2-cookbook

I’ll be your editor

Nice start.

[Angel_De_La_Noche]

Cool.

Probably I should learn git eventually, cause all the good stuff happens on github

Svn is totally outdated

[samdark (Alexander Makarov)]

Yeah. github is opensource everything

[komodo (J Theill)]

You are fast as always Samdark

Just found this: Gitbook.

Maybe it can be used to generate the book itself? Or would it be to much/complicated to start with?

[yiqing95]

exciting news for creating the yii2 cookbook . we need this

Interesting this, huh!

[samdark (Alexander Makarov)]

It’s starting to take a shape: https://github.com/samdark/yii2-cookbook/blob/master/book/index.md Come on, let’s do it!

[evercode (Ikon321)]

Love the cookbook, these are very useful tips. I hope more people contribute…

[paskuale (Pellicanipasquale)]

Great job Orey and thanks for share code

[thimt8-yii]

There are many scattered information.

Has guide, has the cookbook, has extensions, has Wiki, and have suggested a location only do more with code examples.

It would be great if all that was found in one location, well cataloged.

[samdark (Alexander Makarov)]

Cookbook isn’t wiki type where everything can end up. It’s more or less verified/edited so it makes sense to create it as a separate project.

Sometimes we may want to avoid too much RBAC, and make our auth system pure role-based.

That is, something like this:

public function behaviors()

{

    return [

        'access' => [

            'class' => 'yii\web\AccessControl',

            'rules' => [

                [

                    'allow' => true,

                    'roles' => ['moderator', 'admin'], // only these roles are allowed to access

                ],

            ],

        ],

    ];

}

But Yii2 has only two roles by default: ? and @.

Here’s how it can be done.

First, we override AccessRule class:

<?php


namespace app\components;


class AccessRule extends \yii\web\AccessRule

{

    protected function matchRole($user)

    {

        if (empty($this->roles)) {

            return true;

        }

        foreach ($this->roles as $role) {

            if ($role === '?' && $user->getIsGuest()) {

                return true;

            } elseif ($role === '@' && !$user->getIsGuest()) {

                return true;

            } elseif (!$user->getIsGuest()) {

                // user is not guest, let's check his role (or do something else)

                if ($role === $user->identity->role) {

                    return true;

                }

            }

        }

        return false;

    }

}

Next, we inject this class into access configuration:

public function behaviors()

{

    return [

        'access' => [

            'class' => 'yii\web\AccessControl',

            'ruleConfig' => [

                'class' => 'app\components\AccessRule' // <==== HERE IT IS!

            ],

            'rules' => [

                [

                    'allow' => true,

                    'roles' => ['moderator', 'admin'],

                ],

            ],

        ],

    ];

}

And we’re done here.

(thx Qiang for the tip)

This is great, but how do I set the users to have the roles of ‘moderator’ or ‘admin’?

You can create extra "role" field in users table.

PS. Notice that RBAC was rewritten heavily since that post.

This one is maybe known but, it may saves someone’s ass

in a query, you can also pass an array of data

$model->find()

->where(["col_name"=>["value1","value2","value3"]])

-all();

This will make a sql sentence ‘where in(…,…,…)’

I would really love if the yii2 cookbook would advanced, I think it’s a wonderful idea, as well as this post
