# StupidSpaces

You know, that kind of user, that kind of user ... 

>"your app has a bug, if I put white spaces before and after the string, 

   it saves to the database with the spaces", 

   

>"but why are you inserting those spaces if they aren't needed there?"

>"just to test if is a well built system", 

   

>"don't you have anything more important to do?" 

   

Then you call the user boss and say 

>"hey, you know that user wants I strip all the leading and trailing spaces 

from all the tables with string attributes just because he thinks it's

important", and the boss

>"I think he has a point there, please do it."

>"Grrr. Stupid spaces (or perhaps, stupid user)."

So, unless we want to use a lot of `before_save` callbacks, we can use this gem

here.

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'stupid_spaces'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install stupid_spaces

## Usage

Include the module inside the ActiveRecord model you want it to strip the

spaces:

```ruby

class Person < ActiveRecord::Base

  include StupidSpaces

end

```

Ok, now **all** the string attributes of Person will be stripped. If you set a name like, say:

```ruby

person = Person.first

person.name = '         Eustáquio Rangel              '

puts person.name

=> 'Eustáquio Rangel'

```

Notice that only the *leading* and *trailing* spaces are removed, not the spaces inside the string.

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run

`rake test` to run the tests. You can also run `bin/console` for an interactive

prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To

release a new version, update the version number in `version.rb`, and then run

`bundle exec rake release`, which will create a git tag for the version, push

git commits and tags, and push the `.gem` file to

[rubygems.org](https://rubygems.org).
