VistasHow can I disable deletion of inline objects when using django-reverse-admin?
This is my ModelAdmin:
class ComputerAdmin(ReverseModelAdmin):
list_display = ('employee', 'ip', 'mac', 'name', 'hardware')
list_filter = ('employee__branch', )
inline_type = 'tabular'
inline_reverse = ['hardware', ]
show_full_result_count = False
This is how it shows when adding a new computer:
As you can see, I don't want to have the delete column and delete icon, because I have a foreign key so only one element is allowed. How can I do that?
Does django-reverse-admin have anything like has_delete_permisison for inlines only and not the whole ModelAdmin? I have already searched in documentation with no results, which is why I am posting here.
I updated my code as below:
class HardwareInline(admin.TabularInline):
model = Hardware
def has_delete_permission(self, request, obj=None):
return False
class EmployeeAdmin(admin.ModelAdmin):
list_display = ('group', 'branch', 'name')
list_filter = ('group', )
class ComputerAdmin(ReverseModelAdmin):
list_display = ('employee', 'ip', 'mac', 'name', 'hardware')
list_filter = ('employee__group', 'employee__branch', )
inline_type = 'tabular'
inline_reverse = [ { 'field_name': 'hardware', 'admin_class': HardwareInline } ]
The delete column disappeared from inline, but I get a delete button under it:

We can find the answer from this GitHub issue:
You need to explicitly create an inline, and add a has_delete_permission method to it:
class HardwareInline(admin.TabularInline):
model = Hardware
def has_delete_permission(self, request, obj=None):
return False
And then in your ReverseModelAdmin, you need to specify the 'admin_class':
class ComputerAdmin(ReverseModelAdmin):
list_display = ('employee', 'ip', 'mac', 'name', 'hardware')
list_filter = ('employee__group', 'employee__branch')
inline_type = 'tabular'
inline_reverse = [
{'field_name': 'hardware', 'admin_class': HardwareInline},
]
This should hide the "Delete" checkbox.
