Multi-Table Django Join - mysql

Question

Relatively new to Django. I'm building a light CRM in Django. The MYSQL database I built uses associative entities to help deal with many-to-many relationships.
I'm trying to use the associative entity "contactdeal" to connect "deals" with "contacts".
See models and views below.
Models:
class Account1(models.Model):
id = models.AutoField(primary_key=True)
name = models.CharField(max_length=255, blank=True, null=True)
address = models.CharField(max_length=255, blank=True, null=True)
city = models.CharField(max_length=255, blank=True, null=True)
state = models.CharField(max_length=255, blank=True, null=True)
country = models.CharField(max_length=255, blank=True, null=True)
description = models.CharField(max_length=255, blank=True, null=True)
phone = models.CharField(max_length=255, blank=True, null=True)
email = models.CharField(max_length=255, blank=True, null=True)
biztype = models.CharField(max_length=255, blank=True, null=True)
notes = models.CharField(max_length=255, blank=True, null=True)
class Meta:
managed = False
db_table = 'account'
class Contact1(models.Model):
contact_id = models.AutoField(primary_key=True)
first_name = models.CharField(max_length=255, blank=True, null=True)
last_name = models.CharField(max_length=255, blank=True, null=True)
account_id = models.ForeignKey(Account1, models.DO_NOTHING, db_column='account_id', blank=False, null=False)
contact_notes = models.TextField(blank=True, null=True)
contact_email = models.CharField(max_length=255, blank=True, null=True)
contact_phone = models.CharField(max_length=255, blank=True, null=True)
contact_status = models.CharField(max_length=255, blank=True, null=True)
class Meta:
managed = False
db_table = 'contact'
class Contactdeal(models.Model):
contactdeal_id = models.AutoField(primary_key=True)
contactdeal_deal_fk = models.ForeignKey('Deal', models.DO_NOTHING, db_column='contactdeal_deal_fk', blank=True, null=True)
contactdeal_contact_fk = models.ForeignKey(Contact1, models.DO_NOTHING, related_name='contactdeal_contact_fk', db_column='contactdeal_contact_fk', blank=True, null=True)
class Meta:
managed = False
db_table = 'contactdeal'
class Deal(models.Model):
deal_id = models.AutoField(primary_key=True)
deal_name = models.CharField(max_length=255, blank=True, null=True)
est_value = models.DecimalField(max_digits=13, decimal_places=2, blank=True, null=True)
deal_notes = models.TextField(blank=True, null=True)
class Meta:
managed = False
db_table = 'deal'
View:
def deal(request):
deal = Contactdeal.objects.select_related('contactdeal_contact_fk', 'contactdeal_deal_fk')
template = loader.get_template('deal.html')
context = {
'deal' : deal,
}
return HttpResponse(template.render(context, request))
Template:
{% for x in deal %}
<tbody>
<tr class="table-active">
<td>{{x.contactdeal_deal_fk.deal_name}}</td>
<td>{{x.contactdeal_deal_fk.est_value}}</td>
<td>{{x.contactdeal_contact_fk.first_name}}</td>
<td>{{x.contactdeal_contact_fk.account_id}}</td>
<td>Update</td>
<td>Delete</td>
</tr>
</tbody>
{% endfor %}
for the most part, I've been successful using the select_related approach to join both contacts and deals using the associative entity contactdeal.
Where this falls short, however, is when I want to show the "account" each "contact" belongs to. I can show "account_id" which is the FK that links the "contact" table and "account" table, but I can't seem to come up with a way to add another join that will allow me to use the "account_id" FK in the contact table to pull the name associated with that "account_id" in the "account" table.

Answer 1

I think I figured it out. I am going to try to create a view in MYSQL that achieves the connection I am looking to establish and turn that into its own model, not managed using Django.
