How to configure Swashbuckle to omit Template / Entity / Schema from the documentation

Question

I'm trying to build a filter for Swashbuckle to omit in the API documentation the models / Entities / Schema of the project, keeping the controllers. The technology employed is Swashbuckle.AspNetCore v3.0.0 / Swagger UI v3.17.1. I already found ways to omit a certain method in the controller, but I wanted to omit the models in the documentation. I found a problem similar to mine, including hiding only the properties.

Follow filter code

public void Apply(OpenApiSchema schema, SchemaFilterContext context)
{
    if (!(context.ApiModel is ApiObject))
    {
        return;
    }

    var model = context as ApiObject;

    if (schema?.Properties == null || model?.ApiProperties == null)
    {
        return;
    }

    var excludedProperties = model.Type
        .GetProperties()
        .Where(
            t => t.GetCustomAttribute<SwaggerExcludeAttribute>() != null
        );

    var excludedSchemaProperties = model.ApiProperties
        .Where(
            ap => excludedProperties.Any(
                pi => pi.Name == ap.MemberInfo.Name
            )
        );

    foreach (var propertyToExclude in excludedSchemaProperties)
    {
         schema.Properties.Remove(propertyToExclude.ApiName);
    }
}

Would anyone have any suggestions to hide only the models / Entities / Schemas from the documentation and not just their attributes? As the image below.

Answer 1

Set DefaultModelsExpandDepth to -1 in your Swashbuckle / Swagger UI configuration:

app.UseSwaggerUI(c =>
{
    ...
    c.DefaultModelsExpandDepth(-1);
}

Answer 2

At least for me I had to do something like:

internal class SwaggerSchemaFilter : ISchemaFilter
{
    public void Apply(OpenApiSchema schema, SchemaFilterContext context)
    {
        var keys = new System.Collections.Generic.List<string>();
        var prefix = "My.Prefix";
        foreach(var key in context.SchemaRepository.Schemas.Keys)
        {
            if (key.StartsWith(prefix))
            {
                keys.Add(key);
            }
        }

        foreach(var key in keys)
        {
            context.SchemaRepository.Schemas.Remove(key);
        }
    }
}
