Adding constraints
|
|
==================================
|
|
|
|
Constraints can be used on top of type validations provided by the base fields described in the previous chapter.
|
|
The base class `BaseConstraint` is used as base type and contains shared functionality.
|
|
|
|
Since fields are usually only validated when there's change detected, it's usually necessary to add
|
|
back references to chain validations.
|
|
|
|
DependConstraint
|
|
-------------------------
|
|
|
|
When choices depend on each other, you can use the `DependConstraint` type.
|
|
The following example makes `sslurlonly` depend on the `sslbump` option, since the `<reference>`
|
|
tag is needed to make sure when one of the settings changes, the other is validated again too.
|
|
|
|
.. code-block:: xml
|
|
|
|
<sslbump type="BooleanField">
|
|
<Constraints>
|
|
<check001>
|
|
<type>DependConstraint</type>
|
|
<addFields>
|
|
<field1>sslurlonly</field1>
|
|
</addFields>
|
|
</check001>
|
|
</Constraints>
|
|
</sslbump>
|
|
<sslurlonly type="BooleanField">
|
|
<Constraints>
|
|
<check001>
|
|
<reference>sslbump.check001</reference>
|
|
</check001>
|
|
</Constraints>
|
|
</sslurlonly>
|
|
|
|
|
|
AllOrNoneConstraint
|
|
-------------------------
|
|
|
|
Make sure that options are only valid when selected in combination.
|
|
|
|
SingleSelectConstraint
|
|
-------------------------
|
|
|
|
When options are not valid in combination, you can hook options together so only one of the
|
|
options can be selected at the same time.
|
|
|
|
UniqueConstraint
|
|
-------------------------
|
|
|
|
This constraint helps to make sure all items within an `ArrayField` are unique, such as the following example
|
|
which makes sure all "filenames" in this set are unique.
|
|
|
|
.. code-block:: xml
|
|
|
|
<filename type="TextField">
|
|
<Constraints>
|
|
<check001>
|
|
<type>UniqueConstraint</type>
|
|
</check001>
|
|
</Constraints>
|
|
</filename>
|
|
|
|
|
|
ComparedToFieldConstraint
|
|
-------------------------
|
|
|
|
The ComparedToFieldConstraint compares the value of the current field to the value of a referenced field
|
|
on the same level (for example in the same ArrayField).
|
|
It is for example used for the rspamd_ plugin, to ensure that some values are in the correct order.
|
|
This constraint can be used to compare numeric values.
|
|
|
|
.. _rspamd: https://github.com/opnsense/plugins/blob/master/mail/rspamd/src/opnsense/mvc/app/models/OPNsense/Rspamd/RSpamd.xml
|
|
|
|
Example:
|
|
|
|
::
|
|
|
|
<check003>
|
|
<ValidationMessage>This field must be bigger than the greylist score.</ValidationMessage>
|
|
<type>ComparedToFieldConstraint</type>
|
|
<field>greylistscore</field>
|
|
<operator>gt</operator>
|
|
</check003>
|
|
|
|
In this example, the valueof the current field must be greater than the value of the field "greylistscore".
|
|
|
|
Field values:
|
|
|
|
================= ====================================================================================
|
|
ValidationMessage Validation message (translateable) which will be shown in case the validation fails.
|
|
type ComparedToFieldConstraint
|
|
field the other field which we reference
|
|
operator The operator to check the value. Valid operators are gt, gte, lt, lte, eq, neq
|
|
================= ====================================================================================
|
|
|
|
Operators:
|
|
|
|
=== =====================
|
|
gt greater than
|
|
gte greater than or equal
|
|
lt lesser than
|
|
lte lesser than or equal
|
|
eq equal
|
|
neq not equal
|
|
=== =====================
|
|
|
|
|
|
|
|
|
|
SetIfConstraint
|
|
------------------------------------
|
|
|
|
The SetIfConstraint is used to make some fields conditionally mandatory. It is mainly used in the nginx_
|
|
plugin for example to choose an implementation type. In general the other field should be an OptionField,
|
|
but does not need to. In general it is a good idea to hide or show fields which are (not)
|
|
required by an implementation in the frontend as well to simplify the web interface.
|
|
Please note: the checked field is intended to be on the same level (for example ArrayField).
|
|
|
|
.. _nginx: https://github.com/opnsense/plugins/blob/master/www/nginx/src/opnsense/mvc/app/models/OPNsense/Nginx/Nginx.xml
|
|
|
|
Example:
|
|
|
|
::
|
|
|
|
<check001>
|
|
<ValidationMessage>This field must be set.</ValidationMessage>
|
|
<type>SetIfConstraint</type>
|
|
<field>match_type</field>
|
|
<check>id</check>
|
|
</check001>
|
|
|
|
In this example, the value will be mandatory, if the field "match_type" has the value "id".
|
|
|
|
Field Values:
|
|
|
|
================= ====================================================================================
|
|
ValidationMessage Validation message (translateable) which will be shown in case the validation fails.
|
|
type SetIfConstraint
|
|
field the other field which we reference
|
|
check The value of the other field which makes this field required
|
|
