Get verbose name of foreign key from objects _meta dynamically in Django

For simplicity sake, with models like the following:

 class Plan(models.Model)
     name = models.CharField(max_length=255, verbose_name="Phone Plan Name")
     monthly_charge = models.FloatField()
 class Company(models.Model):
     name = models.CharField(max_length=255, verbose_name="Company Full Name")
     phone_plan = models.ForeignKey(Plan)
 class Client(models.Model):
     name = models.CharField(max_length=255, verbose_name="Client Full Name")
     company = models.ForeignKey(Company)

Given a string, I want to know if there is an easy way to retrieve the verbose name of a model attribute even if that string traverses through foreign keys.

I know that I can get the verbose name of a Client attribute by

Client._meta.get_field("name").verbose_name

and this would result in "Client Full Name".

But what if I had the string "company__phone_plan__name", I cannot simply use

Client._meta.get_field("company__phone_plan__name").verbose_name

to arrive at "Phone Plan Name" as it yields an error.

These strings will be dynamic, so I am wondering what is the easiest way to arrive at the proper verbose name of an attribute, even if it traverses models?

This particular case is using Django 1.11

Solution

This is not so good answer but if you need what you want you can use this function:

def get_verbose_name(model, string):
    fields = string.split('__')

    for field_name in fields[:-1]:
        field = model._meta.get_field(field_name)

        if field.many_to_one:
            model = field.foreign_related_fields[0].model
        elif field.many_to_many or field.one_to_one or field.one_to_many:
            model = field.related_model
        else:
            raise ValueError('incorrect string')

    return model._meta.get_field(fields[-1]).verbose_name

This function gets model name and string and return verbose name

You can use it like so:

get_verbose_name(Client, 'company__phone_plan__name')
