How force DJANGo choice MEDIA_URL or STATIC_URL in template?

[setivo...@gmail.com]

I need choice base url MEDIA_URL (/media/) - for uploaded user picture, or STATIC_URL (/static/) - picture by default

I am try next:

p><img src="{% if account.accountuserinfo.picture %}MEDIA{% else %}STATIC{% endif %}_URL{{ account.accountuserinfo.picture_url }}" alt="picture_for_{{ account.name }}" id="account_picture"></p>

, but result is MEDIA_URL(STATIC_URL) and path to file.

I am next try:

{% templatetag openvariable %} url 'entry_list' {% templatetag closevariable %}

but result is {{ MEDIA_URL }} or {{ STATIC_URL }} (not working)

may by anyone known how solved this problem

---------------------------------------------------

It seems like you want to use display a default picture if the user does not have one.

    {% load static %}

    {% static "images/default_pic.jpg" as default_pic %}

    {{ account.accountuserinfo.picture|default:default_pic }}

Cheers

it does not help, because I am image by default 

class AccountUserInfo(models.Model):

    MAN = 'man'

    WOMAN = 'woman'

    VAGUE = 'vague'

    GENDER_CHOICES = [

        (VAGUE, 'Vague'),

        (MAN, 'Male'),

        (WOMAN, 'Female'),

    ]

    def dispatch_account_media_files(instance, filename):

        return '{0}/app_accounts/{1}'.format(instance.account.__str__(), filename)

    account = models.OneToOneField(AccountUser, on_delete=models.CASCADE)

    first_name = models.CharField('First name', max_length=50, blank=True, null=True)

    last_name = models.CharField('Last name', max_length=50, blank=True, null=True)

    picture = models.ImageField('Picture', upload_to=dispatch_account_media_files, blank=True, null=True)

    gender = models.CharField('Gender', max_length=10, choices=GENDER_CHOICES, default=GENDER_CHOICES[0][0])

    country = CountryField('Country', blank_label='(select country)', blank=True, null=True)

    birthday = models.DateField('Birthday', blank=True, null=True)

----------------------------------

    @property

    def picture_url(self):

        if self.picture and hasattr(self.picture, 'url'):

            return self.picture.url

        else:

            return '/project_static/images/default-picture.png'

But thanks for the advice

You should work your {% if %} statement this way:

{% if account.accountuserinfo.picture %}

    <img src="{{ MEDIA_URL }}{{ account.accountuserinfo.picture }}">

{% else %}

    <img src="{{ STATIC_URL }}{{ account.accountuserinfo.picture_url }}">

{% endif %}

Trying to cram all of that together within the template is awful to read, and doesn't work as you've seen.

It would also make more sense to have the URL path of the default image set somewhere other than inside of a property. Either as a global variable for the model class, or even within your settings.py file and brought in as part of the template context if it can be used by other areas of the system. Querying an object instance for a static value like that is not good style.

I am solved problem next variant:

in model

----------------------

@property

def account_user_picture(self):

    if self.picture:

        return self.picture.url

    else:

        return settings.STATIC_URL + 'project_static/images/default-picture.png'

in templates

------------------------------------------

<img src="{{ account.accountuserinfo.account_user_picture }}">

And all worked

Thanks
