How do I perform query in django templates - django

Question

I have Two Modeks, Employee Type and Employees:
class EmployeeType(models.Model):
type = models.CharField(max_length=500)
enable = models.BooleanField(default=True)
class Employee(models.Model):
date = models.DateTimeField(default=timezone.now)
emptype = models.ForeignKey(EmployeeType, on_delete=models.CASCADE, verbose_name='Type')
male = models.IntegerField(verbose_name='Male', default=0)
female = models.IntegerField(verbose_name='Female', default=0)
others = models.IntegerField(verbose_name='Others', default=0)
This is the relevant view from my forms.py
class EmployeeForm(forms.ModelForm):
class Meta:
model=Employee
exclude = ('date',)
def __init__(self, *args, **kwargs):
super(EmployeeForm, self).__init__(*args, **kwargs)
self.fields['emptype'].widget.attrs = {'class':'form-control'}
self.fields['male'].widget.attrs = {'class':'form-control','placeholder':'Male'}
self.fields['female'].widget.attrs = {'class':'form-control','placeholder':'Female'}
self.fields['others'].widget.attrs = {'class':'form-control','placeholder':'Others'}
and here is views.py:
def addEmployee(request):
employee = EmployeeForm(request.POST or None)
context = {
'employees':employee,
}
return render(request,'add_employee.html',context)
and here is my add_employee.html
<div class="form-group">
<table class="table">
<thead>
<tr>
<th scope="col">Type</th>
<th scope="col">Male</th>
<th scope="col">Female</th>
<th scope="col">Others</th>
</tr>
</thead>
<tbody>
{% for em in employees.emptype %}
<tr>
<td>{{em}}</td>
<td><input type="number" name="male_{{em.id}}" step="any" required="" id="id_male" class="form-control" value="0" ></td>
<td><input type="number" name="female_{{em.id}}" step="any" required="" id="id_female" class="form-control" value="0" ></td>
<td><input type="number" name="others_{{em.id}}" step="any" required="" id="id_others" class="form-control" value="0"></td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
Now I am facing problem in getting EmployeeType ID in name field i.e. {{em.id}}. How I can fix this?

Answer 1

You can overrides the default name of the objects of this class by using str method inside the model to show the whatever name you want.
class EmployeeType(models.Model):
type = models.CharField(max_length=500)
enable = models.BooleanField(default=True)
def __str__(self):
return self.type
this way the context will show whatever name is defined in the method or you can user the context_name.field_name which in you case is {{em.type}}
