Using Django
1

Hello guys i’ve a simple question for django. I have a model like this:

    Link_tr 
    Link_en
    Link_fr

And at template i want to use like this: {{pk1.Link_{{LANGUAGE_CODE}}}} but django dont accept. I hope someone can solve my problem.

Actually, this isn’t so much an I18n issue as it is a template / data attribute issue.

The quick answer is that there’s no built-in facility for retrieving a “variably named” field within the template system. You’ve got a couple of options:

  1. Add your own “getattr”-style tag. (Some searching may help you find an example or three)
  2. Perform this lookup in your view and add the results to your context before rendering the template
  3. Add a method to your model to retrieve the desired value and return it, then access that method in the template.

If you need to do this a lot with many different models / fields, you may find #1 to be most useful. If you need to do it a lot but only on 1 field, #3 may be to your advantage. But if you’re only doing this once or twice with one or two fields, #2 may be the least work overall.

Mr whitesell, i understand your suggestion but because of the document’s language i can’t learn fully and solve it. If you or someone can make direct code i’ll be very very happy. Here’s my full code:

models.py

class Sektorler(models.Model):
Link_tr = models.SlugField(max_length=1000,verbose_name=“Link - Tr”,null=True,blank=True,unique=True)
Link_en = models.SlugField(max_length=1000,verbose_name=“Link - En”,null=True,blank=True,unique=True)
Isim_tr = models.CharField(max_length=200,verbose_name=“İsim - Tr”,null=True,blank=True)
Isim_en = models.CharField(max_length=200,verbose_name=“İsim - En”,null=True,blank=True)
def save(self, *args, **kwargs):
self.Link_tr = slugify(self.Isim_tr)
self.Link_en = slugify(self.Isim_en)
super(BuyukUrunCesitleri, self).save(*args, **kwargs)

At the template page for example index page:

{% for pk1 in productcategory1 %}
<div class="col" style="max-width: 200px">
<div class="card">
<img class="card-img-top" src="/static/Img1/ProductCategorys/{{pk1.Resim}}" alt="{{pk1.Isim_tr}}" />
{% union "pk1.Isim_" "current_language" as aaaa%}
<div class="card-body py-4 px-0 text-center">
<a class="stretched-link text-body" href="{% url 'products' productcategory='tasima-ekipmanlari' products=aaaa %}" >
<h6>{{aaaa}}<small>(11)</small></h6>
</a>
</div>
</div>
</div>
{% endfor %}

First I made a simple tag who union strings but it didn’t work for example return of {{aaaa}} = pk1.Isim1_tr(or en) but i want to value of pk1.Isim1_tr(or en). If you understand me, can you write direct code of ‘getattr’ or be more spesific(For 2 full day i’m working on it and now i’m starting to become crazy).

You can start from this snippet as a base. You’ll have to modify it to work with two arguments - the base field name and the language code. (You’ll do the concatenation in the function, not in the template.)
