Display foriegnkey fields in Django template for a CreateView - django

Question

I am trying to display a checklist in the CreateView using the values in the ForeignKey fields for descriptions.
models.py
class Structure(models.Model):
name = models.CharField(max_length = 30)
description =models.CharField(max_length = 300, null=True, blank=True)
def __str__(self):
return self.name
class SelectedFramework(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
structure = models.ForegignKey(Structure)
selected = models.BooleanField(default = False)
views.py
class FrameworkCreateView(generic.CreateView):
model = SelectedFramework
fields =['structure', 'selected']
template_name = 'catalogue/structure.html'
def form_valid(self, form):
form.instance.user = self.request.user
return super(FrameworkCreateView, self).form_valid(form)
structure.html
{% extends 'catalogue\base.html' %}
{% block container %}
<h2>{% block title %}Structures{% endblock title %}</h2>
<form action="" method="post">
{% csrf_token %}
{% for field in form %}
<div class="col-sm-10">{{form.structure}} {{form.selected}}</div><br>
{% endfor %}
</div>
</form>
{% endblock %}
The code above works but will display the ForeignKey 'structure' as a dropdown list with the values of __str__. Is there a way to display string for structure.name and structure.description with the checkbox from selected in the CreateView?

Answer 1

In your template use:
{{ form.structure.name }}
{{ form.structure.description}}

Answer 2

You can write custom form, override the save method and create Structure object manually there:
class FrameworkForm(forms.ModelForm):
structure_name = forms.CharField(required=True)
structure_description = forms.CharField(required=False)
class Meta:
model = SelectedFramework
fields = [
'structure_name', 'structure_description', 'selected'
]
def save(self, commit=False):
instance = super(FrameworkForm, self).save(commit=False)
structure = Structure(
name=self.cleaned_data.get('structure_name'),
description=self.cleaned_data.get('structure_description')
)
structure.save()
instance.structure = structure
instance.save()
return instance
Also add form_class = FrameworkForm to your view instead of fields = ['structure', 'selected']
EDIT:
Perhaps you want something like this:
<ul>
{% for structure in form.fields.structure.choices.queryset %}
<li>{{ structure.name }} - {{ structure.description }}</li>
{% endfor %}
</ul>

Answer 3

If you want to get fields by iterating in the template. You have to use-
{% for field in form %}
{{ field }}
{% endfor %}
don't have to use any dot notation to get the field. If you want to get the label of the field you can use {{ field.label}} usually before {{field}}
