What is the best practice regarding the *.gitignore* file with Git; should it be excluded from the repository or included? If it&#39;s conditional, what are the conditions for each circumstance?

What is the fastest way to detect if a vector has at least 1 `NA` in R?  I&#39;ve been using:

    sum( is.na( data ) ) &gt; 0

But that requires examining each element, coercion, and the sum function.

I want to take the last 10 instances of a model and have this code:
   

     Model.objects.all().order_by(&#39;-id&#39;)[:10]

Is it true that firstly pick up all instances, and then take only 10 last ones?
Is there any more effective method?

I want to convert JSON data into a Python object.

I receive JSON data objects from the Facebook API, which I want to store in my database.  

My current View in Django (Python) (`request.POST` contains the JSON):

    response = request.POST
    user = FbApiUser(user_id = response[&#39;id&#39;])
    user.name = response[&#39;name&#39;]
    user.username = response[&#39;username&#39;]
    user.save()

- This works fine, but how do I handle complex JSON data objects?   
- Wouldn&#39;t it be much better if I could somehow convert this JSON object into a Python object for easy use?

How do I override an admin template (e.g. admin/index.html) while at the same time extending it (see https://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-vs-replacing-an-admin-template)?

First - I know that this question has been asked and answered before (see https://stackoverflow.com/questions/3967801/django-overriding-and-extending-an-app-template) but as the answer says it isn&#39;t directly applicable if you&#39;re using the app_directories template loader (which is most of the time).

My current workaround is to make copies and extend from them instead of extending directly from the admin templates. This works great but it&#39;s really confusing and adds extra work when the admin templates change.

It could think of some custom extend-tag for the templates but I don&#39;t want to reinvent the wheel if there already exists a solution.

On a side note: Does anybody know if this problem will be addressed by Django itself?

I&#39;ve checked out tons of tutorials for django AJAX forms, but each one of them tells you one way of doing it, none of them is simple and I&#39;m a bit confused since I&#39;ve never worked with AJAX.

I have a model called &quot;note&quot;, a modelform for it, and inside the template I need that everytime a note element sends the stop() signal (from jQuery Sortables) django updates the object.

My current code:

**views.py**

    def save_note(request, space_name):
    
        &quot;&quot;&quot;
        Saves the note content and position within the table.
        &quot;&quot;&quot;
        place = get_object_or_404(Space, url=space_name)
        note_form = NoteForm(request.POST or None)
            
        if request.method == &quot;POST&quot; and request.is_ajax:
            msg = &quot;The operation has been received correctly.&quot;          
            print request.POST
    
        else:
            msg = &quot;GET petitions are not allowed for this view.&quot;
            
        return HttpResponse(msg)

**JavaScript:**

    function saveNote(noteObj) {
        /*
            saveNote(noteObj) - Saves the notes making an AJAX call to django. This
            function is meant to be used with a Sortable &#39;stop&#39; event.
            Arguments: noteObj, note object.
        */
        var noteID = noteObj.attr(&#39;id&#39;);
        
        $.post(&quot;../save_note/&quot;, {
            noteid: noteID,
            phase: &quot;Example phase&quot;,
            parent: $(&#39;#&#39; + noteID).parent(&#39;td&#39;).attr(&#39;id&#39;),
            title: $(&#39;#&#39; + noteID + &#39; textarea&#39;).val(),
            message: &quot;Blablbla&quot;,
        });
    }

The current code gets the data from the template and prints it in the terminal. I don&#39;t know how I can manipulate this data. I&#39;ve seen some people manages the data through jqueryforms to send the data to django.

How can I access the data sent by AJAX and update the note object?

How to POST a django form with AJAX &amp; jQuery

In Django templates, you can use either `{{ _(&quot;Hello World&quot;) }}` or `{% trans &quot;Hello World&quot; %}` to mark strings to be translated. In docs, the “official” approach seems to be the [`{% trans %}`](https://docs.djangoproject.com/en/1.8/topics/i18n/translation/#trans-template-tag) tag, but the `_()` syntax is mentioned too [once](https://docs.djangoproject.com/en/1.8/topics/i18n/translation/#string-literals-passed-to-tags-and-filters).

**How these approaches differ** (except syntax) and why should be one preferable rather than the other?

One difference is that you obviously can&#39;t use `{% trans %}` with tags and filters. But does that mean that I can just use `_()` everywhere, like `{{ _(&quot;String&quot;) }}`? It works and looks much cleaner and more consistent than using `{% trans &quot;String&quot; %}` with standalone strings and `_()` with tags and filters.

I have dates in ISO&amp;nbsp;8601 format in the database, `%Y-%m-%d`. However, when the date is passed on to the template, it comes out as something like `Oct. 16, 2011`.

Is there a way that I can manipulate the format to whatever I want?

My dictionary looks like this(Dictionary within a dictionary):

    {&#39;0&#39;: {
        &#39;chosen_unit&#39;: &lt;Unit: Kg&gt;,
        &#39;cost&#39;: Decimal(&#39;10.0000&#39;),
        &#39;unit__name_abbrev&#39;: u&#39;G&#39;,
        &#39;supplier__supplier&#39;: u&quot;Steve&#39;s Meat Locker&quot;,
        &#39;price&#39;: Decimal(&#39;5.00&#39;),
        &#39;supplier__address&#39;: u&#39;No\r\naddress here&#39;,
        &#39;chosen_unit_amount&#39;: u&#39;2&#39;,
        &#39;city__name&#39;: u&#39;Joburg, Central&#39;,
        &#39;supplier__phone_number&#39;: u&#39;02299944444&#39;,
        &#39;supplier__website&#39;: None,
        &#39;supplier__price_list&#39;: u&#39;&#39;,
        &#39;supplier__email&#39;: u&#39;ss.sss@ssssss.com&#39;,
        &#39;unit__name&#39;: u&#39;Gram&#39;,
        &#39;name&#39;: u&#39;Rump Bone&#39;,
    }}

Now I&#39;m just trying to display the information on my template but I&#39;m struggling. My code for the template looks like:

```html
{% if landing_dict.ingredients %}
  &lt;hr&gt;
  {% for ingredient in landing_dict.ingredients %}
    {{ ingredient }}
  {% endfor %}
  &lt;a href=&quot;/&quot;&gt;Print {{ landing_dict.recipe_name }}&lt;/a&gt;
{% else %}
  Please search for an ingredient below
{% endif %}
```

It just shows me &#39;0&#39; on my template?

I also tried: 

```html
{% for ingredient in landing_dict.ingredients %}
  {{ ingredient.cost }}
{% endfor %}
```

This doesn&#39;t even display a result.

I thought perhaps I need to iterate one level deeper so tried this:


```html
{% if landing_dict.ingredients %}
  &lt;hr&gt;
  {% for ingredient in landing_dict.ingredients %}
    {% for field in ingredient %}
      {{ field }}
    {% endfor %}
  {% endfor %}
  &lt;a href=&quot;/&quot;&gt;Print {{ landing_dict.recipe_name }}&lt;/a&gt;
{% else %}
  Please search for an ingredient below
{% endif %}
```

But this doesn&#39;t display anything.

What am I doing wrong?
