Merb#merge_env; Personalized, mergeable Environments[Feature][Patch]
Reported by coryodaniel(midget_nuts|codaniel) | March 26th, 2008 @ 09:23 PM | in 0.9.4
Since merbs environments are pretty abstract (i.e: Merb doesn't explode if you use an environment thats not "test", "production", "development) I have been taking the opportunity to use personalized environments. I can create a "stage" environment or a "localdev" environment that are configured differently that the standard three environments.
What this patch lets you do is call Merb.runs_like "this_environment" in one of your environment.rb files. It will apply that environment config before/after (depending on placement) the settings in the current environment *.rb file.
This allows cool things like having a personal environment locally that maybe specifies a port that you always want to run on, but besides that you always want to use the settings from "Development.rb"
You can do (my_env.rb):
Merb.runs_like "development"
Merb::Config.use {|x| x[:port] = 3004}

I like this, but I want to play with it a little before applying.

I'm not very familiar with how Merb interacts with various ORMs. I would like to see this feature (if implemented) also use the same database connection that merb is "running like"

I got this working where you can load the other envs database
In my personal env:
Merb.runs_like "development", true
#This will load the development environment, override it with my env's settings, but use the dev database, so you dont have to create a crap load of environments in the database.yml file
Will upload patch tomorrow, I need food right now :)
BTW, you can 'merge' as many environment files as you want, they get merged in as the #runs_like method is called during your env.rb file . . . only one can have the "true" flag set to use the database though (obviously)

please do not use port in environment examples! #229 tells why, try to use something like memcache / memory for session store in different environments. This is in case you are going to add example above to docs.

Updating this ticket with new examples, and the patches for #runs_like to optionally connect to merged environments database...

Patch to merb-core.rb (this will require a patch in activerecord and datamapper plugins to optionally load the merged db, will submit in a bit)

I like this as well. My only issue is I don't like the name ;) Can we come up with a better name for this?
suggestions:
Merb.run_as 'staging'
Merb.use_env 'staging
??

Just a reminder there is the other half of the patch to make the DB portion work...
This doesn't access the data by the public method, (merge_env) so no updates need to be done to its patch
