I was thinking about this last night after spending some time messing with a project plugin for Vim. This morning I hacked up a quick patch for the rails app\_generator to automatically setup a vim project file. It works, but I knew it wouldn’t be a particularly good fit for the core of rails - still nothing ventured etc. Anyway it was suggested that perhaps peopel on the rails list might be intrigued… Anyway if you’re a vim user, this might make starting your rails projects easier (note I’m a long time vi user, but in no way would I consider myself advanced, so any suggestions would be helpful). # 1 here’s the patch to rails app\_generator (eg C:\ruby\lib\ruby\gems\1.8\gems\rails-0.14.3\lib\rails\_generator\generators\applications\app\app\_generator) Index: app\_generator.rb — app\_generator.rb (revision 2943) +++ app\_generator.rb (working copy) @@ -10,7 +10,8 @@ def initialize(runtime\_args, runtime\_options = {}) super usage if args.empty? - @destination\_root = args.shift - @destination\_root = args.shift - @app\_name = File.basename(File.expand\_path(@destination\_root)) @socket = MYSQL\_SOCKET\_LOCATIONS.find { |f| File.exists?(f) } @socket = ‘/path/to/your/mysql.sock’ if @socket.blank? end @@ -26,6 +27,10 @@ # Root m.file “fresh\_rakefile”, “Rakefile” m.file “README”, “README” - ``` m.template "vim4rails", "vim4#{@app_name}", :assigns => { ``` - ``` :app_name => @app_name, ``` - ``` :location => File.expand_path(@app_name) ``` - ``` } # Application m.template "helpers/application.rb", ``` “app/controllers/application.rb” @@ -34,7 +39,7 @@ ``` # database.yml and .htaccess m.template "configs/database.yml", "config/database.yml", ``` :assigns =\> { - ``` :app_name => ``` File.basename(File.expand\_path(@destination\_root)), - ``` :app_name => @app_name, :socket => @socket } m.template "configs/routes.rb", "config/routes.rb" ``` after patching app\_generator you need to add this file (contents below) to eg if your rails gem is installed like mine (on windows) c:\ruby\lib\ruby\gems\1.8\gems\rails-0.14.3 2 Save this as “vim4rails” \<%= app\_name %\>=\<%= location %\> CD=. { View=app/views CD=. { } Controllers=app/controllers CD=. filter=“_.rb" { } Models=app/models CD=. filter="_.rb” { } YAML=config CD=. filter=“_.yml" { } DDL=db CD=. filter="_.ddl _.sql" { } Tests=test CD=. { Fixtures=fixtures CD=. filter="_.yml” { } Functional=functional CD=. filter=“_.rb" { } Unit=unit CD=. filter="_.rb” { } } Stylesheet=public/stylesheets CD=. filter=“\*.css” { } } 3 Now you need to download and set up the project plugin I used - download from here : [project.tar.gz - Organize/Navigate projects of files (like IDE/buffer explorer) : vim online](http://www.vim.org/scripts/script.php?script_id=69), follow the included instructions to install the plugin on your system 4 Create a new rails app with “rails #{your\_app}” 5 Check that inside the root of your rails app there’s a file called vim4#{your\_app} 6 open Vim 7 (and finally) Load the project file for your rails app… go into command mode (ESC) type :Project /vim4#{your\_app} 8 enjoy! I’m quite happy with it, I’d like to turn it into a real generator, any other suggestions welcome. Kev ---

Hi, I tried following the instructions on Agile Web Development w/ Rails book to install RoR on my machine (windows XP). And, afterwards tried to create a scaffold using: “ruby.exe script/generate scaffold Product Admin” as mentioned in the book. And, I got the following error: “Before updating scaffolding from new DB schema, try creating a table for your model (Product)” As I mentioned my development machine is Windows XP (installed ruby 1.8.2, rails 0.14.3), and am using mysql 4.1 on a linux machine. Connect string in database.yml is correct (verified everything over and over again). Also, when I look at the development log, I see an error: “Lost connection to MySQL server during query: SHOW FIELDS FROM products” I tried executing this sql, and it works fine too, which means products table is there and can be found without problems… Also, I can connect to the same database from java using jdbc, and I can connect and execute this fine… Am I missing something here? Have been trying to get this working for the last 2 days, and it keeps giving this error. I tried downgrading to rails 0.13.1. But, getting the same error. Can anyone pleasee help? This is driving me crazy and I am pretty much stuck here… Thanks… * * * Yahoo! FareChase: Search multiple travel sites in one click. [http://farechase.yahoo.com](http://farechase.yahoo.com) ---

Have you updated the database.yml to point to the correct db? ---

Thank you so much for this workaround! I have been fighting with trying to get this working and was about to give up. Thanks! Regards, Brett ---

Thanks! > > Regards, > Brett Everyone, I am having the same error using XP. I tried to use the above workaround, but that line is not in my mysql\_adapter.rb file. Any other ideas. I am running version 1.82 with mysql 4.1 Thanks in advance, geek001 ---

Hi, Cabbar, please try to comment out the row require ‘active\_record/vendor/mysql411’ in mysql\_adapter which is in my installation is located at: E:\ruby\lib\ruby\gems\1.8\gems\activerecord-1.13.0\lib\active\_record\connection\_adapters\mysql\_adapter.rb The resulting file would after that begin with: module ActiveRecord class Base # Establishes a connection to the database that’s used by all Active Record objects. def self.mysql\_connection(config) # :nodoc: # Only include the MySQL driver if one hasn’t already been loaded unless self.class.const\_defined?(:Mysql) begin require\_library\_or\_gem ‘mysql’ # The C version of mysql returns null fields in each\_hash if Mysql::VERSION is defined ConnectionAdapters::MysqlAdapter.null\_values\_in\_each\_hash = Mysql.const\_defined?(:VERSION) rescue LoadError =\> cannot\_require\_mysql # Only use the supplied backup Ruby/MySQL driver if no driver is already in place begin require ‘active\_record/vendor/mysql’ # require ‘active\_record/vendor/mysql411’ ##################### this is the row ######################## # The ruby version of mysql returns null fields in each\_hash ConnectionAdapters::MysqlAdapter.null\_values\_in\_each\_hash = true rescue LoadError raise cannot\_require\_mysql end end end This helped me (and others whom advice I’ve followed) - connection-bindings to mysql, native ones more than the default ruby-bindings seem to be a bit of a problem at the moment… regards Jan P.
