Functions

func All added in v0.7.0 

func All(validators ...validator.Map) validator.Map

All returns a validator which ensures that any configured attribute value attribute value validates against all the given validators.

Use of All is only necessary when used in conjunction with Any or AnyWithAllWarnings as the Validators field automatically applies a logical AND.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/mapvalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
	"github.com/hashicorp/terraform-plugin-framework/types"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.MapAttribute{
				ElementType: types.StringType,
				Required:    true,
				Validators: []validator.Map{
					// Validate this Map value must either be:
					//  - More than 5 elements
					//  - At least 2 elements, but not more than 3 elements
					mapvalidator.Any(
						mapvalidator.SizeAtLeast(5),
						mapvalidator.All(
							mapvalidator.SizeAtLeast(2),
							mapvalidator.SizeAtMost(3),
						),
					),
				},
			},
		},
	}
}

Output:

func AlsoRequires added in v0.7.0 

func AlsoRequires(expressions ...path.Expression) validator.Map

AlsoRequires checks that a set of path.Expression has a non-null value, if the current attribute or block also has a non-null value.

This implements the validation logic declaratively within the schema. Refer to [datasourcevalidator.RequiredTogether], [providervalidator.RequiredTogether], or [resourcevalidator.RequiredTogether] for declaring this type of validation outside the schema definition.

Relative path.Expression will be resolved using the attribute or block being validated.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/mapvalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/path"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
	"github.com/hashicorp/terraform-plugin-framework/types"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.MapAttribute{
				ElementType: types.StringType,
				Optional:    true,
				Validators: []validator.Map{
					// Validate this attribute must be configured with other_attr.
					mapvalidator.AlsoRequires(path.Expressions{
						path.MatchRoot("other_attr"),
					}...),
				},
			},
			"other_attr": schema.StringAttribute{
				Optional: true,
			},
		},
	}
}

Output:

func Any added in v0.7.0 

func Any(validators ...validator.Map) validator.Map

Any returns a validator which ensures that any configured attribute value passes at least one of the given validators.

To prevent practitioner confusion should non-passing validators have conflicting logic, only warnings from the passing validator are returned. Use AnyWithAllWarnings() to return warnings from non-passing validators as well.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/mapvalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.MapAttribute{
				Required: true,
				Validators: []validator.Map{
					// Validate this Map value must either be:
					//  - Between 1 and 2 elements
					//  - At least 4 elements
					mapvalidator.Any(
						mapvalidator.SizeBetween(1, 2),
						mapvalidator.SizeAtLeast(4),
					),
				},
			},
		},
	}
}

Output:

func AnyWithAllWarnings added in v0.7.0 

func AnyWithAllWarnings(validators ...validator.Map) validator.Map

AnyWithAllWarnings returns a validator which ensures that any configured attribute value passes at least one of the given validators. This validator returns all warnings, including failed validators.

Use Any() to return warnings only from the passing validator.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/mapvalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.MapAttribute{
				Required: true,
				Validators: []validator.Map{
					// Validate this Map value must either be:
					//  - Between 1 and 2 elements
					//  - At least 4 elements
					mapvalidator.AnyWithAllWarnings(
						mapvalidator.SizeBetween(1, 2),
						mapvalidator.SizeAtLeast(4),
					),
				},
			},
		},
	}
}

Output:

func AtLeastOneOf added in v0.7.0 

func AtLeastOneOf(expressions ...path.Expression) validator.Map

AtLeastOneOf checks that of a set of path.Expression, including the attribute this validator is applied to, at least one has a non-null value.

This implements the validation logic declaratively within the tfsdk.Schema. Refer to [datasourcevalidator.AtLeastOneOf], [providervalidator.AtLeastOneOf], or [resourcevalidator.AtLeastOneOf] for declaring this type of validation outside the schema definition.

Any relative path.Expression will be resolved using the attribute being validated.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/mapvalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/path"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
	"github.com/hashicorp/terraform-plugin-framework/types"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.MapAttribute{
				ElementType: types.StringType,
				Optional:    true,
				Validators: []validator.Map{
					// Validate at least this attribute or other_attr should be configured.
					mapvalidator.AtLeastOneOf(path.Expressions{
						path.MatchRoot("other_attr"),
					}...),
				},
			},
			"other_attr": schema.StringAttribute{
				Optional: true,
			},
		},
	}
}

Output:

func ConflictsWith added in v0.7.0 

func ConflictsWith(expressions ...path.Expression) validator.Map

ConflictsWith checks that a set of path.Expression, including the attribute the validator is applied to, do not have a value simultaneously.

This implements the validation logic declaratively within the schema. Refer to [datasourcevalidator.Conflicting], [providervalidator.Conflicting], or [resourcevalidator.Conflicting] for declaring this type of validation outside the schema definition.

Relative path.Expression will be resolved using the attribute being validated.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/mapvalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/path"

			"example_attr": schema.MapAttribute{
				ElementType: types.StringType,
				Optional:    true,
				Validators: []validator.Map{
					// Validate this attribute must not be configured with other_attr.
					mapvalidator.ConflictsWith(path.Expressions{
						path.MatchRoot("other_attr"),
					}...),
				},
			},
			"other_attr": schema.StringAttribute{
				Optional: true,
			},
		},
	}
}

Output:

func ExactlyOneOf added in v0.7.0 

func ExactlyOneOf(expressions ...path.Expression) validator.Map

ExactlyOneOf checks that of a set of path.Expression, including the attribute the validator is applied to, one and only one attribute has a value. It will also cause a validation error if none are specified.

This implements the validation logic declaratively within the schema. Refer to [datasourcevalidator.ExactlyOneOf], [providervalidator.ExactlyOneOf], or [resourcevalidator.ExactlyOneOf] for declaring this type of validation outside the schema definition.

Relative path.Expression will be resolved using the attribute being validated.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/mapvalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"

					}...),
				},
			},
