I'm trying to add the sandbox to my rails spree application and have run into this error
(using windows 8/powershell with Rails 4.1.6). I'm going by this manual: https://github.com/spree/spree/issues/411
This link Use older version of Rake
seems to have a similar issue but I am not sure how to take the necessary steps to achieve it.
When I try:
C:\Ruby193\openUpShop> bundle exec rake sandbox
I get:
rake aborted!
Don't know how to build task 'sandbox'
I'm am new to rails and am still not sure how everything works so a throughout explanation
with step by step instructions would be greatly appreciated! Thanks.
you can use a file sandbox.rb
# use example: rake task:sub_task -- --sandbox
if ARGV.any? {|arg| arg == '--sandbox' }
puts "** << USING SANDBOX!! >> **"
# beginning
$sandbox = -> do
ActiveRecord::Base.connection.begin_transaction
end
# end
at_exit do
ActiveRecord::Base.connection.rollback_transaction
end
end
then only you need add at the beginning of your task.rake file
require_relative 'path_to_your/sandbox.rb'
..and add at the beggining of your task code
desc "description task"
task example_task: :environment do
$sandbox.call if $sandbox.present?

// This is a question for Ruby on Rails
I have a Rails Tasks that should take arguments from command line.
Looks like this :
task update: :environment do
if (ARGV[1] == "DEBUG")
DEBUG = true
else
DEBUG = false
end
Now I can run the command line :
rails call:update DEBUG
and it works !
But after the task was finished I got also the message :
rails aborted!
Don't know how to build task 'DEBUG' (See the list of available tasks with `rails --tasks`)
I looking already around the community, but all what I found was quite old and seems not to be compatible with Rails 6 ! So thats the reason why I asking here.
I try with the code you shared above I got the same error of rake abort.
its Comming because they way you calling the rake task with the argument it assume the DEBUG is another task so it try to find and give this error.
Here is proper way of doing it
I did some modification in the code to get rid of the error use the following code it will work perfectly
task :update, [:value] => [:environment] do |t, args|
if (args[:value] == "DEBUG")
DEBUG = true
p "Value is True"
else
DEBUG = false
p "Value is False"
end
end
it works perfectly
You can also put this task in the namespace and then call it from there as well
namespace :debug_task do
# task code here what I mentioned above
end
and then call it to form the terminal like this
rake debug_task:update["DEBUG"]
So I have the following task in rails running on jruby:
desc "Creates a new site with args: name, api_url (must be http(s)://api.something.com/v1/ - note the ending slash), api_key"
task :add_new_site, [:name, :api_url, :api_key] => :enviroment do | t, args |
if !Site.find_by_site_name(args[:name])
new_site = Site.new(site_name: args[:name], site_api_url: args[:api_url], site_api_key: args[:api_key])
if new_site.save!
puts "Created new Site: " + args[:name]
end
else
puts "This site already exists."
end
end
When I run it as such:
$ bin/rake add_new_site['sample', 'sample.com', 'addasdsd']
rake aborted!
Don't know how to build task 'add_new_site[sample,'
You can see the error.
What am I doing wrong to receive this? I have other tasks that take one argument and they seem to work fine.
Note: yes this is in a .rake and not a .rb file
Update One:
You can see from the below out put that I saw what was required of this task, and I tried it and it still failed:
$ bin/rake -T add_new_site ['sample', 'sample.com', 'addasdsd']
rake add_new_site[name,api_url,api_key] # Creates a new site with args: name, api_url (must be http(s)://api.something.com/v1/ - note the ending slash), api_key
$ bin/rake add_new_site['sample','sample.com','addasdsd']
rake aborted!
Don't know how to build task 'enviroment'
Tasks: TOP => add_new_site
(See full trace by running task with --trace)
I seem to be getting a different error?
You have a typo: enviroment instead of environment
That's why you are getting this error:
rake aborted!
Don't know how to build task 'enviroment'
I need to make a custom Rails 4 rake task to delete all records in database using ip:
task :delete_records, [:ip] => :environment do |t, args|
User.destroy_all(ip: args.ip)
end
I try to execute it using the following command:
bundle exec rake delete_records["127.0.0.1"] but I've the error:
no matches found: delete_records["127.0.0.1"]
How can I fix it? Thank in advance!
I'm guessing you used this answer for help - although we've done rake tasks before, we've never used one with arguments like this
--
Test
We've created custom rake tasks before - they reside in lib/tasks
I would test out yours by doing the following:
#lib/tasks/your_task.rake
desc "Remove all records for particular IP"
task :delete_records, [:id] => :environment do
args.with_defaults(:ip => "127.0.0.1")
User.destroy_all ip: args.ip
end
If this does not work, it will mean there's something wrong with the definition of your task (it's not in the correct folder or something)
The above should determine if your argument definition is the issue; if it isn't you should let me know so we can work to fix it
I want to run asset precompile task inside the rails application,As I had many dependencies who will change the code,in that case all the time whenever they change i need to run the script as I cant give server access to them so I am providing the GUI for them from that they alone can run the script,so,I have built UI to run the task with some parameter like
system("Template='#{params[:template]}' Theme='#{params[:theme]}' rake assets:precompile)
I am getting two values from UI(params[:template],params[:theme]).Another thing i want to run this task in another path(site path) means Admin side UI is there that task should execute in Site directory,
if(params[:theme_script] == "true")
template=Template.where(:name => params[:template]).first
if template
theme = template.themes.where(:name => params[:theme]).first
if theme
# Dir.chdir "#{THEMEPATH}"do
# `Template="#{template.name}" Theme="#{theme.name}" rake assets:precompile`
# end
# sleep 10
# system("#{Rails.root.to_s}/lib/shell_script.sh")
# RunRake.run_rake(template.name,theme.name)
# Dir.chdir "#{THEMEPATH}"do
# Rake::Task['assets:precompile'].invoke
# end
ENV["Template"] = template.name
ENV["Theme"] = theme.name
precompile_task = "bundle exec rake assets:precompile --trace 2>&1"
output = Dir.chdir(THEMEPATH) { %x[ #{precompile_task} ] }
flash[:notice] = "Asset created successfully"
else
flash[:notice] = "U have enter invalid data"
end
else
flash[:notice] = "U have enter invalid data"
end
end
This is my code am checking multiple condition and am allowing to execute the task.
I have tried this code by putting in controller and lib, but this is not working.
I have tried with shell script also.
Could please anyone can help me.
You can just setup an environment variable for rails, and then issue #invoke method from a controller. So, prepare the files:
gemfile
gem 'rake'
config/initializers/rake.rb:
Rake.load_rakefile Rails.root.join( 'Rakefile' )
app/controllers/your_controller:
ENV["Template"] = template.name
ENV["Theme"] = theme.name
Rake::Task[ 'assets:precompile' ].invoke
Issue bundle install, then run console rails c, and type:
Rake::Task.tasks.map(&:name).grep 'assets:precompile'
# => ["assets:precompile"]
As you can see, the task assets:precompile is loaded successfully. Then just issue the action for the controller.
To run the task for an other rails app you shell run also the other ruby instance, similar to as you had done:
system( "other_app_run.sh '#{template.name}' '${theme.name}'" )
other_app_run.sh:
#!/bin/bash
source "$HOME/.rvm/scripts/rvm"
cd /other/app/path
export Template="$1"
export Theme="$2"
rake assets:precompile
I've got a plugin that is a bit heavy-weight. (Bullet, configured with Growl notifications.) I'd like to not enable it if I'm just running a rake task or a generator, since it's not useful in those situations. Is there any way to tell if that's the case?
It's as simple as that:
if $rails_rake_task
puts 'Guess what, I`m running from Rake'
else
puts 'No; this is not a Rake task'
end
Rails 4+
Instead of $rails_rake_task, use:
File.basename($0) == 'rake'
I like NickMervin's answer better, because it does not depend on the internal implementation of Rake (e.g. on Rake's global variable).
This is even better - no regexp needed
File.split($0).last == 'rake'
File.split() is needed, because somebody could start rake with it's full path, e.g.:
/usr/local/bin/rake taskname
$0 holds the current ruby program being run, so this should work:
$0 =~ /rake$/
It appears that running rake will define a global variable $rakefile, but in my case it gets set to nil; so you're better off just checking if $rakefile has been defined... seeing as __FILE__ and $FILENAME don't get defined to anything special.
$ cat test.rb
puts(global_variables.include? "$rakefile")
puts __FILE__
puts $FILENAME
$ cat Rakefile
task :default do
load 'test.rb'
end
$ ruby test.rb
false
test.rb
-
$ rake
(in /tmp)
true
./test.rb
-
Not sure about script/generator, though.
The most stable option is to add $is_rake = true at the beginning of Rakefile and use it from your code.
Use of $0 or $PROGRAM_NAME sometimes will fail, for example when using spring and checking variables from config/initializers
You can disable the plugin using environment variable:
$ DISABLE_BULLET= 1 rake some:task
And then in your code:
unless ENV['DISABLE_BULLET']
end
We could ask this
Rake.application.top_level_tasks
In a rails application, this is an empty array, whereas in a Rake task, the array has the task name in it.
top_level_tasks probably isn't a public API, so it's subject to changes. But this is the only thing I have found.
