[Solved]-Reverse Inlines in Django Admin

0👍

No, as A needs to have a ForeignKey to B to be used as an Inline. Otherwise how would the relationship be recorded once you save the inline A?

You cannot do it as told by timmy O’Mahony. But you can make B inline in A if you want. Or maybe you can manipulate how django display it in

def unicode(self):

models.py

class A(models.Model):
    name = models.CharField(max_length=50)
    def __unicode__(self):
        return self.name

class B(models.Model):
    name = models.CharField(max_length=50)
    a = models.ForeignKey(A)

admin.py

class B_Inline(admin.TabularInline):  
    model = B
class A_Admin(admin.ModelAdmin):
    inlines = [
        B_Inline,
    ]
admin.site.register(A, A_Admin)
admin.site.register(B)

Or maybe you want to use many-to-many relationship?

models.py

class C(models.Model):
    name = models.CharField(max_length=50)
    def __unicode__(self):
        return self.name
class D(models.Model):
    name = models.CharField(max_length=50)
    cs = models.ManyToManyField(C)

admin.py

class C_Inline(admin.TabularInline):  
    model = D.cs.through
class D_Admin(admin.ModelAdmin):
    exclude = ("cs",)
    inlines = [
        C_Inline,
    ]
admin.site.register(C)
admin.site.register(D, D_Admin)

Of course you can do this. Every relationship be it 1-1, m2m or FK will have a reverse accessor. (more on the FK reverse access here)

class A_Inline(admin.TabularInline):  
    model = A.b_set.through

class B_Admin(admin.ModelAdmin): 
    inlines = [A_Inline]
