So, the title is quite self explanatory, but here's the following ..
rake db:create
rake aborted!
No rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)
Any help would be appreciated.
What is your current working directory when calling the rake db:create command? Are you in the root of the Rails app?
You have to be in the root of the Rails app that you are creating.
Currently you must be one step up.
Case I:
Check out your directory. If you are in same directory where your application is available then you wont' get is this message. You are getting this message because you are out of your application directory. To check you present directory you can use this command
pwd
Case II
You might missing your Rakefile. Check it out in your directory. For example,
$ ls
app/
bin/
config/
db/
...
If you don't find Rakefile then create new one. Puts this code
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
require File.expand_path('../config/application', __FILE__)
Blog::Application.load_tasks

As the question states, where is the Rakefile in a Railsapp?
In my app it is no where to be found. I'm working on an app with another developer and he's just pushed code to the Rakefile as such:
7 Rakefile
## -0,0 +1,7 ##
+# Add your own tasks in files placed in lib/tasks ending in .rake,
+# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
+
+require File.expand_path('../config/application', __FILE__)
+require 'rake'
+
+Newapp::Application.load_tasks
Although, I can't find this code anywhere in the actual app. Please help clear this up for me!
Thanks!
Conventionally, the Rakefile usually goes at the Rails root of your project (this is the location first generated when you ran rails new ...).
rake can also be run by using a Rakefile anywhere, by using rake -f path/to/my/rakefile.rb, so if you need to diverge from the convention for some reason, that's possible too.
However, note that many third-party services presume that it's possible to run rake from the root of your project and get the desired result (e.g. heroku rake).
In a fresh(ish) rails project, the Rakefile looks like this:
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
require File.expand_path('../config/application', __FILE__)
Blog::Application.load_tasks
Yet rake routes produces the following output:
cpe-74-72-73-47:rails-blog-example djechlin$ rake routes
home_index GET /home/index(.:format) home#index
root / home#index
I don't understand how rake works so that it can get to the routes file or the routes task. Per the command line usage documentation, rake is invoked as
rake [options ...] [VAR=VALUE ...] [targets ...]
But the page has no explanation of what the targets are. I assume rake is called directly on the routes.rb file from this and that Rakefile is not related, but I can't confirm this at all.
A Rakefile contains executable Ruby code. Anything legal in a ruby script is allowed in a Rakefile.
When you trigger rake routes you call this piece of Ruby code .
Actually, the Rakefile is very related, and rake isn't called directly on routes.rb at all. Rake needs a rakefile. The magic happens inside load_tasks, which load the numerious Rails-specific Rake tasks that come with the framework.
When you invoke Rake, it looks for a Rakefile. The Rakefile is just Ruby. In your default Rakefile, first it includes ../config/application, where your application class (Blog::Application) is defined; then it invokes load_tasks, which is provided by Rails::Application, from which your Blog::Application inherits.
From there there are a million ways for each part of Rails to make Rake tasks available. Typically the core libraries provide Rail ties which expose tasks.
Hey people i know maybe 1% of ruby and need many help...
I migrated a system from one server to another server
When I try to insert an entry to the database using the system, I get the following error (remembering that I use ruby is 2.1):
undefined method `insert_record' for #<Array:0x007fec2a2b2fa0>
i know maybe this is a solution:
http://alok-anand-ror.blogspot.com.br/2013/11/undefined-method-insertrecord-for.html
i have gems of rake instaled 0.9.2 and 0.9.2.2
when i try run "rake db:migrate" (I think it would solve, I do not know) i received
rake aborted No rake file found
if somebody can help me I greatly appreciate.
thanks in advanced.
it seems your Rakefile is missing .
Check your rails folder should contain Rakefile with following content
#!/usr/bin/env rake
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
require File.expand_path('../config/application', __FILE__)
Demo::Application.load_tasks
~
and
undefined method `insert_record' for #<Array:0x007fec2a2b2fa0>
this error is because of incompatibility issues with rails and ruby , try upgrading rails
I have defined a rake task as follows in a file called file_locker_task.rake
namespace :myspace do
task :process => :environment do
FileLocker.lock_files
end
end
How do I execute this rake task from the command line?
I tried:
rake myspace:process and rake process but both are throwing an error like this:
rake aborted!
Don't know how to build task 'process'
Run rake -T -A from your Rails home directory to see all the tasks that rake knows about. Yours must be in that list for rake to run it.
By default, in a Rails app, rake looks in the lib/tasks directory and its subdirectories for your .rake files. Check that. (I suspect this is the problem.)
According to docs
Any ruby file (including other rakefiles) can be included with a standard Ruby require command.
-
Additional rake files (with the file extension “.rake”) may be placed in rakelib directory located at the top level of a project (i.e. the same directory that contains the main Rakefile). Also, rails projects may include additional rake files in the lib/tasks directory.
I'm trying to do a rake migrate, but I'm getting an error when I do this:
rake db:migrate
What I get back:
rake aborted!
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)
/Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2377:in `raw_load_rakefile'
(See full trace by running task with --trace)
How do I fix this? Thanks.
are you in the root directory of your project?
is there a file called Rakefile?
Make sure the current directory is within your project.
So for example:
cd ~/projects/greatness/
rake db:migrate
The error message seems rather self explanatory. There is no rakefile for rake to operate on.
If your rails structure is broken in some way, I'd suggest calling rails in a temporary folder then bringing across the script directory and rake file.
