CakePHP：尝试生成架构时出错

Question

I'm trying to start using CakePHP schema: app/Console/cake schema generate

I get the following error:

Welcome to CakePHP v2.3.0 Console
---------------------------------------------------------------
App : app
Path: /Applications/MAMP/htdocs/mysite/app/
---------------------------------------------------------------
Cake Schema Shell
---------------------------------------------------------------
Error: Database connection "Mysql" is missing, or could not be created.

This is confusing because the site is running fine, so the DB credentials in Config/database.php are correct.

Update: Because I'm using MAMP, I added the following to my Config/database.php in the $defualt array:

'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',

Now I don't get the original error, but rather some new ones:

Welcome to CakePHP v2.3.0 Console

App : app

---------------------------------------------------------------

Looks like CakePHP is freaking out about the ENUM fields.

Answer 1

As described pretty definitively here...

Cakephp + enum support : unable to save or select enum 0 and 1

...CakePHP does not like ENUM fields. It looks like the Console tools related to the schema are going to work with them there.

Answer 2

Old question, I know. But I just fixed this issue yesterday while working in a really old project of mine.

If you still need this kind of solution, I posted on this git public repository.

https://github.com/matheuscmpm/cakephp-schema-enum

You basicly need to alter the Datasource/Database/Mysql.php file to insert the ENUM as an accepted type and them alter the Model/CakeSchema.php to handle them.

If you don't want to alter your cakephp 2.x files, you can copy them to your project app folder, just like I did. In this README.md file, you can see what exactly I changed in this both files, you can replicate the same solution to handle SET type fields as well.

I just did that to work with MySQL, so with you need to another database, you will also need to change a couple things in others datasource/database files.

Cheers.
