Django display multiple uploaded files - django

Question

I am trying to display multiple uploaded file URLs but I'm not sure how to do it. I am a form that the users can use to upload multiple files that are working perfectly but now I want to be able to display these files. For instance, a company can have more than one file.
class InternationalCompany(models.Model):
International_company_Name = models.CharField(max_length=50)
International_company_Id = models.CharField(max_length=50)
options = (
('Yes', 'Yes'),
('No', 'No'),
)
Does_it_have_a_Financial_Dealers_License = models.CharField(max_length=20, choices=options, null=True)
Register_Office = models.TextField(max_length=500, null=True)
Beneficial_owner = models.CharField(max_length=100, null=True)
Beneficial_owner_id = models.FileField(upload_to='passport/pdf/',null=True)
expire_date = models.DateField(null=True)
BO_Phone_number = models.IntegerField(null=True)
BO_Email_Address = models.EmailField(null=True)
BO_Residential_Address = models.TextField(max_length=200, null=True)
def __str__(self):
return self.International_company_Name
class SupportDocuments(models.Model):
Supporting_Documents = models.FileField(upload_to='support_doc/pdf/', null=True)
internationalcompany = models.ForeignKey(InternationalCompany, on_delete=models.CASCADE)
def __str__(self):
return self.Supporting_Documents.url
I try something like this but it only displayed one url of the file instead of the multiple urls for the files that are associate with that company.
{%for company in doc%}
<tr>
<td></td>
<td>{{company.internationalcompany.Beneficial_owner}}</td>
<td>{{company.Supporting_Documents.url}}</td>
</tr>
{%endfor%}
I have also try out this but it doesn't display anything.
{%for company in doc.Supporting_Documents.all%}
{{company.url}}
{%endfor%}
def supporting_doc(request, company_id):
doc = SupportDocuments.objects.filter(id=company_id)
return render(request, 'supporting_doc.html', locals())

Answer 1

First of all, it might be better to use context rather than locals() as discussed here
Second, the way you get the doc queryset is wrong. id=company_id The id of SupportingDocuments is different from company_id. What you really need to do is internationalcompany.id=company_id.
so views.py:
def supporting_doc(request, company_id):
documents = SupportDocuments.objects.filter(internationalcompany.id=company_id)
context = { "documents": documents}
return render(request, 'supporting_doc.html', context)
in template:
{% for doc in documents %}
{{ doc.internationalcompany.Beneficial_owner}}
{{ doc.Supporting_Documents }}
{% endfor %}
On a side note, it may be better to use all lowercases in fields. This way, it is easy to distinguish fields and models.
