[Cayenne-dev] RE: [JIRA] Commented: (CAY-777) Still incorrect: CLONE -Import EOModel - Incorrect Join src/target names are created

Still incorrect: CLONE -Import EOModel - Incorrect Join src/target
names are created
----------------------------------------------------------------------
--------------

Key: CAY-777
URL: https://issues.apache.org/cayenne/browse/CAY-777
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 1.1 [LEGACY]
Environment: EOModels created for WO5.2, Cayenne 1.1B1
Reporter: Kurbachev Yegor
Assigned To: Andrus Adamchik
Priority: Critical
Fix For: 1.1 [LEGACY]


Join source amd target are all created using ObjAttribute names,
instead of column names. This may still work for EOModels where the
two are the same, but it is a nasty bug that completely prevents
import from working in a general case. Looks like a fresh one (after
we switched from DBAttributePair to DBJoin, ca. M6)

Hi!

Although I CAN send you the complete set of files and an SQL
script to
create MySQL database, I have decided to extract the relevant part
only:

<?xml version="1.0" encoding="utf-8"?>
<data-map project-version="2.0">
<property name="defaultPackage" value="com.ray.database"/>
<property name="defaultSchema" value="ray"/>

<db-entity name="boolean_value" catalog="ray">
<db-attribute name="BOOLEAN_VALUE_ID" type="INTEGER"
isPrimaryKey="true" isMandatory="true" length="11"/>
<db-attribute name="NAME" type="VARCHAR"
isMandatory="true" length="200"/>
<db-attribute name="PRIORITY" type="INTEGER"
isMandatory="true" length="11"/>
</db-entity>
<db-entity name="company" catalog="ray">
<db-attribute name="COMPANY_ID" type="INTEGER"
isPrimaryKey="true" isMandatory="true" length="11"/>
<db-attribute name="ELEMENTS_USED_ID" type="INTEGER"
isMandatory="true" length="11"/>
<db-attribute name="MODELS_USED_ID" type="INTEGER"
isMandatory="true" length="11"/>
</db-entity>

<obj-entity name="BooleanValue"
className="com.ray.database.BooleanValue"
dbEntityName="boolean_value">
<obj-attribute name="name" type="java.lang.String"
db-attribute-path="NAME"/>
<obj-attribute name="priority"
type="java.lang.Integer"
db-attribute-path="PRIORITY"/>
</obj-entity>
<obj-entity name="Company"
className="com.ray.database.Company"
dbEntityName="company">
</obj-entity>

<db-relationship name="companyArray" source="boolean_value"
target="company" toMany="true">
<db-attribute-pair source="BOOLEAN_VALUE_ID"
target="ELEMENTS_USED_ID"/>
</db-relationship>
<db-relationship name="companyArray1" source="boolean_value"
target="company" toMany="true">
<db-attribute-pair source="BOOLEAN_VALUE_ID"
target="MODELS_USED_ID"/>
</db-relationship>

<db-relationship name="toBooleanValue" source="company"
target="boolean_value" toMany="false">
<db-attribute-pair source="ELEMENTS_USED_ID"
target="BOOLEAN_VALUE_ID"/>
</db-relationship>
<db-relationship name="toBooleanValue1" source="company"
target="boolean_value" toMany="false">
<db-attribute-pair source="MODELS_USED_ID"
target="BOOLEAN_VALUE_ID"/>
</db-relationship>

<obj-relationship name="companyArray" source="BooleanValue"
target="Company" db-relationship-path="companyArray"/>
<obj-relationship name="companyArray1" source="BooleanValue"
target="Company" db-relationship-path="companyArray1"/>
<obj-relationship name="toBooleanValue" source="Company"
target="BooleanValue" db-relationship-path="toBooleanValue"/>
<obj-relationship name="toBooleanValue1" source="Company"
target="BooleanValue" db-relationship-path="toBooleanValue1"/>
</data-map>

Notice, ELEMENTS_USED_ID became toBooleanValue and MODELS_USED_ID
became
toBooleanValue1.

I am sorry to say, that this is a showstopper for me: for a Company
table, I simply do not know, whether to use toBooleanValue or
toBooleanValue1.

If you need the complete files, I will be happy to send them.

Thanks!!!

-------------------------------------

Yegor,

could you possibly attach an EOModel (or a relevant part of it) to
this
issue? This will significantly speed up the fix. Or if it contains
sensitive company data, could you create a neutral EOModel from
scratch
that reproduces the problem.

Thanks
Andrus

Yegor,

You posted the Cayenne data map, which is probably helpful.

But what's needed (What Andrus asked for) is the EOModel files,
probably at minimal the Company and BooleanValue.plist files.
