I want to mark some relative fields so that they don't appear as links in the UI.

For example, I have User and Address models (some unnecessary details of the description of sqlalchemy models was omitted):

class Address:
    id: int
    zip_code: int
    city: str
    street: str
    house_number: str

    def __repr__(self):
        return f"{self.zip_code}, {self.city}, {self.street}, {self.house_number}"


class User:
    id: int
    name: str
    age: int
    address: Address
    

Also I want create only UserAdmin model

class UserAdmin(ModelView, model=User):
    name = "User"
    name_plural = "Users"

    column_list = ["id", "name"]

On User`s details page I will see the address field as a link leading to an 404 page (because I didn't create AddressAdmin model).

I want to mark address field as a simple text, without any links

Describe the solution you would like.

Add new ModelView attribute, called excluded_relations_names (for example)

class UserAdmin(ModelView, model=User):
    name = "User"
    name_plural = "Users"

    column_list = ["id", "name"]
    
    excluded_relations_names = ["address"]

add some conditions in details.html

...
<tr>
  <td>{{ label }}</td>
  {% set value, formatted_value = model_view.get_detail_value(model, name) %}
  {% if name in model_view._relation_names %}
  {% if is_list( value ) %}
  <td>
    {% for elem, formatted_elem in zip(value, formatted_value) %}
    <a href="{{ model_view._build_url_for('admin:details', request, elem) }}">({{ formatted_elem }})</a>
    {% endfor %}
  </td>
  {% else %}
  {% if name in model_view.excluded_relations_names %} <!-- NEW CHECKS HERE -->
  <td>{{ formatted_value }}</td>
  {% else%}
  <td><a href="{{ model_view._url_for_details_with_prop(request, model, name) }}">{{ formatted_value }}</a>
  </td>
  {% endif %}
  {% endif %}
  {% else %}
  <td>{{ formatted_value }}</td>
  {% endif %}
</tr>
...

Describe alternatives you considered

I found one way to show field as a normal text, without any links:

1. Add some custom field to column_details_list
2. Bind this field to related model
3. Create a label for this custom field

class UserAdmin(ModelView, model=User):
    name = "User"
    name_plural = "Users"

    column_list = ["id", "name"]

    column_details_list = [
        "id",
        "name",
        "age",
        "address_field"  # some custom field name
    ]

    column_formatters_detail = {
        "address_field": lambda m, a: m.address
    }

    column_labels = {
        "address_field": "address"
    }

What if you have much more fields in UserModel? If you want add a custom field to column_details_list, you should explicitly specify all other fields.
Looks like a long workaround.

You can try

``column_exclude_list: List of columns or column names to be excluded in the list page.
` `column_details_exclude_list`: List of columns or column names to be excluded in the details page.`
