Django Inline : how to get inline properties in change_view() django










0














Email model class



 class Email(models.Model)
body_message = models.TextField(max_length = 256, null = False)
#other fields ForeignKey, subject, to etc.


Tabular Inline model.



#Inline Email
class EmailInline(admin.TabularInline):
model = Email


And this is my RequestAdmin model that shows inlines.



class RequestAdmin(admin.ModelAdmin):
inlines = [EmailInline,]

#In change_view() i want to print my inlines properties

def change_view(self, request, object_id, form_url='', extra_context=None):

for inline in self.inlines:
#Here i can remove my specific inline
self.inlines.remove(inline)
#But i want to check my inline_class properties
print(inline.body_message) #This line raise exception
#i want to print inlines body_message


return super(RequestAdmin, self).change_view(request, object_id)


Error image which i am getting.



Exception Value:

type object 'EmailInline' has no attribute 'body_message'



Now how i can get my inline properties (body_message) ?

I think I understand your question a bit better - you want to affect the actual objects that are being populated into the inline form(s), and hide certain ones based on the contents of the body_message property. In that case, you can override the InlineModelAdmin.get_queryset method, which will give you the opportunity to exclude certain items; or the ModelAdmin.get_inline_formsets method, which gives you the opportunity to alter the forms that will be generated for the inline objects:



from django.contrib.admin.options import TabularInline

class EmailInline(TabularInline):
model = Email

# If you want to manipulate the query used to select the related objects:
def get_queryset(self, request):
queryset = super(EmailInline, self).get_queryset(request)
modified_queryset = queryset.exclude(body_message__contains='some string')
return modified_queryset


class RequestAdmin(admin.ModelAdmin):
inlines = [EmailInline, ]

# If you wanted to manipulate the inline forms, to make one of the fields read-only:
def get_inline_formsets(self, request, formsets, inline_instances, obj=None):
inline_admin_formsets =
for inline, formset in zip(inline_instances, formsets):
fieldsets = list(inline.get_fieldsets(request, obj))
readonly = list(inline.get_readonly_fields(request, obj))
prepopulated = dict(inline.get_prepopulated_fields(request, obj))
inline_admin_formset = helpers.InlineAdminFormSet(
inline, formset, fieldsets, prepopulated, readonly,
model_admin=self,
)

# Custom code here - analyze the forms/objects, make changes to the form if desired:
if isinstance(inline, EmailInline):
for form in inline_admin_formset.forms:
if 'some string' in form.instance.body_message:
# this adds the "readonly" attribute to the input widget for the `body_message` field:
form.fields['body_message'].widget.attrs['readonly'] = True

inline_admin_formsets.append(inline_admin_formset)
return inline_admin_formsets
