Hello! Which is the best approach if I want to replace a unique constraint as group. For example in quote: name, customer_reference to be name, customer_reference and other column?

    Did I got you right, you want to replace an existing unique constraint or better extend it with an additional field?

    If that’s the question, just add a file Pyz/Zed/Quote/Persistence/Propel/Schema/spy_quote.schema.xml with the follwing content:

    <?xml version=“1.0”?>
    ” name=“zed” xsi:noNamespaceSchemaLocation=“http://static.spryker.com/schema-01.xsd” namespace=“Orm\Zed\Quote\Persistence” package=“src.Orm.Zed.Quote.Persistence”>

    ” />

    See https://documentation.spryker.com/zed/persistence_layer/database_schema_definition.htm?Highlight=schema#schema-file-merge

    I did that, but the old constraint is still there and works. My constraint is not applied....

    And you did a console propel:schema:copy && propel:diff && propel:migrate && propel:model:build (or propel:install as alternative)?
    What’s in you generated migration file?

    My contrait is created in DB, but not working. Is used the Spryker contraint

    What DB do you use?
    Do you have null values in one of the columns (depending on the DB null values are ignored for constraints)?

    Did you already tested on a database level that the constraint isn’t working (e.g.: Inserting tho datasets with the same name, customer_reference and )?

    Yes, duplicate key value violates unique constraint "spy_quote-unique-name-customer_reference"

    Than I do not understand the problem, maybe you can give a better explanation what did you expect and what do you get instead.

    Maybe you expected that the name of the unique constraint will include your field, that would be a wrong assumption as defines the naming of the constraint. And as you try to overwrite an existing constraint, you shouldn’t change the name.

    I never tested this so this is just a wild guess:
    Did you use the exact same name for the constraint as Spryker uses?

    I added a new unique constraint and I want to use that. That's it!

    In my schema: ```

    <unique name="spy_quote-unique-name-customer_reference-company_reference"> <unique-column name="name"/> <unique-column name="customer_reference"/> <unique-column name="company_reference"/> </unique> </table> ```

    As far as I know you will not be able to remove a constraint that was added by Spryker in the core implementations. Schema files will get merged and unless you actually replace a constaint (hence the name suggestion) it will be there.

    What's wrong with using the same name?
