Re: CharField vs ImageField for Logo

Hi Andreas,

Really appreciate your guidance on this.

I am having trouble understanding this:

3: All that will be stored in your database is a path to the file (relative to MEDIA_ROOT). You'll most likely want to use the convenience url attribute provided by Django. For example, if your ImageField is called mug_shot, you can get the absolute path to your image in a template with {{ object.mug_shot.url }}.

I tried applying the object.logo.url but the logo still doesn't display. Also where did the object and url came from?

Hi,

I think you've made a lot of progress! 

The only thing I think you are missing now is that you should be using the following in your template:

<img src="{{ team.logo.url }}">

See: https://docs.djangoproject.com/en/1.11/ref/models/fields/#filefield and https://docs.djangoproject.com/en/1.11/ref/models/fields/#django.db.models.fields.files.FieldFile.url

Hi Andréas,

Thank you for the response.

I added these lines in my settings.py

MEDIA_DIR = os.path.join(BASE_DIR, 'media')

# Media

MEDIA_ROOT = MEDIA_DIR
MEDIA_URL = '/media/

Then I changed my logo to models.ImageField(upload_to='team_logo'). I also created a 'media' folder inside my project folder which team_logo is a subfolder in it. Tried running the codes again but the logo still wont show.


{% block body_block %}
   
    <p></p>
    <div class="row">
        {% for team in teams %}
        <div class="col-lg-3 col-xs-6 thumbnail">
           
            <img src="{{ team.logo }}">
             <p></p>

            <label>{{ team.name }}</label>
        </div>   
        {% endfor %}
    </div>
   

{% endblock %}

Is there any setting that I missed in media for media?

Thanks,

Jarvis

Hi,

There are a couple of things to think about here.

First of all - just because you put an item on your computer doesn't mean that the icon can be served. For example, if you are running windows and you enter 'C:\pictures\icon.jpg' as the source for the icon, your server won't be able to find it, because the reference 'C:\pictures\icon.jpg' doesn't mean anything for the web browser. The reason the image links you are inputting work is because they probably contain all information, ie http://www.example.com/pictures/icon.jpg.

So you can get that sorted and everything should work. HOWEVER, I really think you should use the media storage functionality of Django for this. Checkout : https://docs.djangoproject.com/en/1.11/topics/files/.

If you add the settings required (MEDIA_ROOT in the settings file) and then change you logo from a CharField to an ImageField AND upload your file via django admin, you should be able to show your file.

Andréas

Hi guys, I am new to django currently stuck in these two.

I am writing my pet project which will display a Team name and their logo. I used these lines for my Team class in mode.spy


class Team(models.Model):
    name = models.CharField(max_length=150)
    logo = models.CharField(null=True, max_length=1000)


    def __str__(self):
        return self.name

Problem is, I can't load the images to my html file My logo images are currently stored in my computer. The images will load properly if I grab an image link online and paste the image location to the Logo field in Admin but if I used the absolute path of the images in my computer, the images wont load. When I tried to inspect the page, I am getting "Image could not load".

Any tips please?
