Rails 3.2 adds a new <code>d</code> shortcut to the command, so now you can write:

It's worth mentioning the <code>-p</code> flag here ("p" for pretend). 

If you add this to the command it will simply do a "test" run and show you what files will be deleted without actually deleting them.

<pre><code>$ rails d controller welcome -p

If you're happy with it, run the command again without the <code>-p</code> flag.

This is a prototype to generate or destroy a controller or model in Rails:

<pre><code>rails generate/destroy controller/model [controller/model Name]
</code></pre>

For example, if you need to generate a User Controller:

<pre><code>rails generate controller User
</code></pre>

or

<pre><code>rails g controller User
</code></pre>

If you want to destroy the User controller or revert to above action
then use:

<pre><code>rails destroy controller User
</code></pre>

or:

<pre><code>rails d controller User
</code></pre>

For example:

<pre><code>rails g model Home name:string

creates a model named <code>home</code> with attribute <code>name</code>. To remove the files and code generated from that command we can use 

<pre><code>rails d model Home

For controller,

<pre><code>rails d controller_name (d stands for destroy)

For Model

<pre><code>rails d model_name

It will remove the model, migration and some of the related test files. (You can see the result in the Terminal window after you have run the command.)
