Added rerating options and fixed two bugs

[ElvinEfendi]

Fixed bugs:

• readOnly option was not set properly
• In rating_for helper disable_after_rate option was being true even if you set options[:disable_after_rate] = false

Rerating functionality:
Now developers can toggle between allowing rerating and no allowing but sending flag while calling letsrate_rateable method

Added documentation for using allow_rerating flag

Hi, can you say me please, how can I set readonly option for specific rating_for field and make that user can rate only ones?

[ElvinEfendi]

Hi, @yozzz. If you are using my fork you can do it as follow:
rating_for @your_object, "dimension", {disable_after_rate: false}

[yozzz]

Sorry for question... you have two main folders generators and letsrate. From generators/letsrate/templates I copied two files as letsrate.js.coffee.erb and rater_controller.rb. In main folder letsrate you have files as helpers.rb, model.rb and version.rb , where I should put it with file letsrate.rb that requires them? After installing gem I don't see similar files.
Thank you for understanding! :)

[ElvinEfendi]

@yozzz you do not need to copy any file. Just install the gem as follow and use the helper in a way I mentioned above:
gem 'letsrate', git: "https://github.com/ElvinEfendi/letsrate.git"

Thought I can't install gem from fork repository, thanks. After command rails g letsrate user getting:
/home/yoz/.rvm/gems/ruby-1.9.3-p448/gems/activesupport-3.2.13/lib/active_support/depend
encies.rb:251:in `require': /home/yoz/.rvm/gems/ruby-1.9.3-p448/bundler/gems/letsrate-b
ce8544a4d49/lib/letsrate/model.rb:62: syntax error, unexpected tLABEL (SyntaxError)
def letsrate_rateable(*dimensions, allow_rerating: false)

@yozzz The changes I made mistakenly was only Ruby 2.0 compatible - I had used keyword arguments. I've just corrected it and now it should work with Ruby 1.9.* as well. You can reinstall and check it again.

I will try it thank you! Is there some way in this gem output stars that
start count from one, I mean first star active by default?

Hi .. For a long time, I have not enough time to mange this gem. But nowadays I'm available. You can check this issue 2-3 days later. Thanks ...

@ElvinEfendi In your generator file you have copy_file 'letsrate.js.cofee.erb', 'app/assets/javascripts/letsrate.js.coffee.erb'. Coffee is mispelled, causing issues.

[ElvinEfendi]

@ericaBradford it seems like the issues I've targeted with this pull requests are already fixed without merging anyway.

[ericaBradford]

@ElvinEfendi How do we change data-disable-after-rate? I can't seem to find how to fix it...

[ElvinEfendi]

@ericaBradford when calling rating_for or rating_for_user method just set disable_after_rate: true

check the helper methods' implementation for more info: https://github.com/muratguzel/letsrate/blob/master/lib/letsrate/helpers.rb

@ElvinEfendi Thank you!!!

[ericaBradford]

@ElvinEfendi I don't know why, but it isn't working...
<%= rating_for @recipe, "Rating", :disable_after_rate => false %>
Am I doing something wrong? I'm trying to make recipes reratable, so I'm pretty sure it's supposed to be set false
