Hello everybody!
I'm new on this forum and in django.
I'm using Python 2.7 environment.
I have the following models.py:
class Categoria(models.Model):
>
> DEFAULT_CATHEGORY = 0
> nome = models.CharField(max_length=255, null=False, default='0')
>
> def __unicode__(self):
> return self.nome
>
> class Produto(models.Model):
>
> nome = models.CharField(max_length=255, null=False)
> pontos_na_compra = models.DecimalField(decimal_places=4,
> max_digits=10, default=0)
> pontos_na_troca = models.DecimalField(decimal_places=4, max_digits=10,
> default=0)
> foto = models.ImageField(upload_to=get_image_path, blank=True,
> null=True)
>
> categoria = models.ForeignKey(
> Categoria,
> default=Categoria.DEFAULT_CATHEGORY
> )
>
> def __unicode__(self):
> return "%s, %s" % (self.nome, self.codigo_depara)
>
I want the relation: each Categoria (cathegory) has many Produto
(products). Is it correct in the model?
I don't have anything on views.py relationed to it.
I want to do some code like this into HTML file:
show CATEGORIA.nome
>
for each PRODUTO in LIST OF PRODUCTS IN CATEGORIA do:
>
show PRODUTO.nome
>
show PRODUTO.pontos_na_compra
>
show PRODUTO.foto
>
end-for
>
I try to use
> {% if categorias %}
> <ul id="flexisel">
> {% for categoria in produto.categoria_set() %}
> <li>
> # SHOW ALL HERE. HOW?
> </li>
> {% endfor %}
> </ul>
> {% else %}
> <p id="flexise">
> Nenhum produto encontrado!
> </p>
> {% endif %}
But it didn't find the categoria_set() method and returns this:
