加载不同的数据库Symfony2

Question

How can I load different database for production and development environment ?

In parameters.yml I have the main database configuration, but I don't know how to add the dev database with differets parameters.

I'm looking for this on Google but I can't find any help.

Maybe with config_dev.yml and config_prod.yml? but I'm not sure how to do that.

Any help would be appreciated. Thanks.

I will do something like this:

Files hierarchy: 1) parameters.yml - for common parameters 2) create parameters_dev.yml - only dev db connection params 3) create parameters_prod.yml - only prod db connection params

In head of config files: 1) config.yml

imports:
    - { resource: parameters.yml }

2) config_dev.yml

imports:
    - { resource: config.yml }
    - { resource: parameters_dev.yml }

3) config_prod.yml

imports:
    - { resource: config.yml }
    - { resource: parameters_prod.yml}

You can use Parameters to store environment-specific (or system-specific) variables easily.

For example, in a config/parameters.yml :

parameters:
    parameter_name: some_value

In config.yml , at the top:

imports:
    - { resource: parameters.yml }

Then, you can substitute a parameter using the syntax "%parameter_name%" where the variable's value should appear.
