Re: If Statement django template
You can't compare the `contract.supplier` attribute directly to a string
like 'IBM', because it is a foreign key to a `Supplier` model instance.
Instead, you need to access the related `Supplier` model's attributes to
compare them. For example, if the `Supplier` model has a `name` attribute,
you can use:
{% if contract.supplier.name == 'IBM' %}
Alternatively, you could also use a `filter()` method on your `QuerySet` to
filter the contracts by their supplier name before passing them to the
template.
contracts = Contract.objects.filter(supplier__name='IBM')
Then you don't need to use the if statement in the template.
{% for contract in contracts %}

Re: If Statement django template
The supplier field in contract is an instance of a Supplier object which is
not a string, so comparing it to a string won't work, instead compare a
field of the supplier instance in the supplier field in contract instance.
Like: {% if contract.supplier.name == "IBM"%}
Do you get it?

If Statement django template
I have the following relationship in a model
class Contract(models.Model):
supplier = models.ForeignKey(
Supplier,
on_delete=models.CASCADE,
verbose_name="Supplier Name",
related_name="contract_suppliers",
)
I am trying to include an if statement in my template but the following
does not work:
{% if contract.supplier == 'IBM' %}
If I replace this with a non-foreign key item then it works fine.
Any help would be appreciated.
