Django Admin: change displayed column name in inline ManyToMany field

问题

I try to translate Django Admin site and I have a problem with ManyToMany TabularInline. My models.py are:

class Doctor(models.Model):
    (...)
    specializations = models.ManyToManyField(Specialization, blank=True, verbose_name='Specjalizacje')

    class Meta:
        verbose_name = 'Lekarz'
        verbose_name_plural = 'Lekarze'

class Specialization(models.Model):
    name = models.CharField(max_length=191, verbose_name='Nazwa')

    class Meta:
        verbose_name = 'Specjalizacja'
        verbose_name_plural = 'Specjalizacje'

And my admin.py looks like:

class SpecializationInline(admin.TabularInline):
    model = Doctor.specializations.through
    verbose_name = 'Specjalizacja'
    verbose_name_plural = 'Specjalizacja'

@admin.register(Specialization)
class SpecializationAdmin(admin.ModelAdmin):
    list_display = ['name',]

@admin.register(Doctor)
class DoctorAdmin(admin.ModelAdmin):
    inlines = [SpecializationInline,]

    # this field is added as inline
    exclude = ['specializations',]

The resulting Django Admin Page looks like:

Everything is translated except of the 'Specialization' column. How can I change its name?

Oke, this is not a full solution. But I hope this helps you out. In the template that is called by TabularInline ,admin/edit_inline/tabular.html.

The part that builds your 'header' part of the table

 <thead><tr>
   ...
 {% for field in inline_admin_formset.fields %}
   {% if not field.widget.is_hidden %}
     <th{% if field.required %} class="required"{% endif %}>
        {{ field.label|capfirst }}
        ...
     </th>
   {% endif %}
 {% endfor %}
 ...
 </tr></thead>

This is telling me you could add a label to a field. So by creating a custom form

class SpecializationForm(ModelForm):
    specializations = forms.ModelChoiceField(queryset=Specialization.objects.all(), label='Specjalizacja')

    class Meta:
        model = Specialization
        fields = ('specializations', )

and call it in your SpecializationInline

class SpecializationInline(admin.TabularInline):
    model = Doctor.specializations.through
    verbose_name = 'Specjalizacja'
    verbose_name_plural = 'Specjalizacja'
    form = SpecializationForm

This should allow you to change the text.
