Using the ModelAdmin.inlines class, there is no DELETE button

[FernandoJMM]

Good Morning,

I'm customizing the ModelAdmin class inlines attribute. The code is this.

class NaveInline(admin.TabularInline):

    model = Nave

    fields = ['codigoNave', 'nave', 'tipoPuesta']

    ordering = ['codigoNave']

    extra = 1

class GranjaAdmin(admin.ModelAdmin):

    fieldsets = [

        (None, {'fields': [('codigoGranja', 'granja'), ('empresa', 'tipoGranja'), ('regimen')]}),

        ('Datos adicionales', {'fields': [('direccion', 'localidad', 'codigoPostal', 

        'provincia', 'region', 'pais', 'telefonoPrincipal', 'telefonoMovil', 

        'fax', 'email', 'ceence','cea', 'maquina', 'clasificacionZootecnica', 

        'formaDeCria', 'notas')], 'classes': ['collapse']}),

    ]

    inlines = [NaveInline]

 

. . . . . .  

Everything works perfectly, I can add granjas / naves, edit granjas / naves, and clear granjas. . but I can not do it is to delete naves that in this case are the lines (inlines).

I do not get any errors, I can see the line selection check but the line deletion button DOES NOT APPEAR.

Thanks for your help,

Fernando

According to https://code.djangoproject.com/ticket/15910:
"When adding a form to an inline formset in the admin interface it has a nice "Remove" link added automatically. These links are however missing from empty rows that have been created as a result from the "extra" option. They are also removed when the form is saved and validation of the form as a whole fails"

Could be that something is invalid and you are not rendering errors in the template?

This is unlikely, you are not overriding the admin's template, right?
