How to add readonly inline on django admin

Question

I am using django 1.4 and I have a many2many field, so when creating the admin site I wanted to add this field as an inline, here is some code:

class SummaryInli

You can make the entire inline readonly by adding:

class UnitsInline(admin.TabularInline):

    def has_change_permission(self, request, obj=None):
        return False

This will prevent anyone from editing the entry from the admin.

Another example that prevents, adding, deletion and displays all the inline fields as readonly:

class ReadOnlyInline(admin.TabularInline):
    def has_change_permission(self, request, obj=None):
        return False

    def has_add_permission(self, request, obj=None):
        return False

    def has_delete_permission(self, request, obj=None):
        return False

    def get_readonly_fields(self, request, obj=None):
        return list(super().get_fields(request, obj))
