You could either go with:

    &lt;%= day_form.text_area :hatch, cols: 30, rows: 10 %&gt;

or you can specify both with the size attribute:

    &lt;%= day_form.text_area :hatch, size: &quot;30x10&quot; %&gt;

For responsiveness I like to make the text area width 100% :

`&lt;%= f.text_area :description, rows: 10, style: &#39;width:100%;&#39; %&gt;`

As text area has both row and column you have to specify both

    &lt;%= text_area(:application, :notes, cols: 40, rows: 15, class: &#39;myclass&#39;) %&gt;

For text field can use

    &lt;%= text_field(:application, :name, size: 20) %&gt;

I want to add [pdb]—the Python debugger—to my toolbox. What&#39;s the best way to get started?

Suppose I have a simple model class like this:

    class TestModel(models.Model):
        testkey = models.ForeignKey(TestModel2)
        ...

When I am creating a TestModel object I have to pass to it an instance of the TestModel2 object to create it:

    testkey =TestModel2.objects.get(id=...)
    TestModel.objects.create(testkey=testkey)

This results in 2 queries to database I suppose, and I have a list of Foreign key IDs that I need to create objects with.

Is it possible to create objects with foreign keys without initially retrieving the foreign key objects?

I have a `text_area` inside a `fields_for`, which is inside a `form_for`.

    &lt;%= day_form.text_area :hatch %&gt;

Is it possible to change the size of the `text_area`? For example: `day_form.text_area size: 5`.

I have a <code>text_area</code> inside a <code>fields_for</code>, which is inside a <code>form_for</code>.
<pre><code class="hljs language-ruby">&#x3C;%= day_form.text_area :hatch %>
</code></pre>
Is it possible to change the size of the <code>text_area</code>? For example: <code>day_form.text_area size: 5</code>.

I have this search in Rails 3:

    Note.where(:user_id =&gt; current_user.id, :notetype =&gt; p[:note_type], :date =&gt; p[:date]).order(&#39;date ASC, created_at ASC&#39;)

But I need the `:date =&gt; p[:date]` condition to be equivilent to `:date &gt; p[:date]`. How can I do this? Thanks for reading.

I poked around StackOverflow and Google, but couldn&#39;t find anyone who has put together a comparison of authentication gems or plugins for Rails (I&#39;m looking for something for Rails 3). What authentication solutions are available for Rails 3, which are most popular, and what are the differences between them?

I have Active Support 3.0.3 installed and Rails 3.0.3 with Ruby 1.8.7.

When I try to use `1.week.ago` I get 

    NoMethodError: undefined method &#39;week&#39; for 1:Fixnum
    from (irb):2

The other core extensions seem to work. I tried it on a friend&#39;s computer (same install specs and legacy versions are on his) with the same results.

What gives?

All of this is in IRB.

Suppose I have the following string 

    @x = &quot;&lt;a href=&#39;#&#39;&gt;Turn me into a link&lt;/a&gt;&quot;

In my view, I want a link to be displayed. That is, I don&#39;t want everything in @x to be unescaped and displayed as a string. What&#39;s the difference between using

    &lt;%= raw @x %&gt;
    &lt;%= h @x %&gt;
    &lt;%= @x.html_safe %&gt;

?

Have gotten these results. As you can see, there are 7 results. If you look carefully (at user_id), there are only 2 users.

I was looking at [this][1], and was thinking I could do something similar so that my array would now look like this:

    [
      #&lt;Activity _id: 4cea6c4572357e00fa00011a, created_at: 2010-11-22 13:12:37 UTC, updated_at: 2010-11-22 13:12:37 UTC, action: &quot;Attend&quot;, user_id: BSON::ObjectId(&#39;4cea2fb872357e00fa000025&#39;), artist_id: nil, media_id: BSON::ObjectId(&#39;4cea447472357e00fa00009a&#39;)&gt;, 
      #&lt;Activity _id: 4cea3ca172357e00fa000062, created_at: 2010-11-22 09:49:21 UTC, updated_at: 2010-11-22 09:49:21 UTC, action: &quot;Attend&quot;, user_id: BSON::ObjectId(&#39;4cea39b772357e00fa000046&#39;), artist_id: nil, media_id: BSON::ObjectId(&#39;4cea3c8b72357e00fa00005e&#39;)&gt;
    ]

I&#39;m not concerned which combination of results are extracted. As long as I have unique user_id&#39;s in the result set. Anyone know how this can be achieved?
