Symfony2，推进固定装置和具体继承

Question

I got an issue with Propel fixtures loading in Symfony2. I have the following schema:

<table name="application" phpName="Application">

   <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" />
   <column name="name" type="varchar" required="true" primaryString="true" />

   <behavior name="timestampable" />

</table>

<table name="application_iphone" phpName="IphoneApplication">

   <column name="store_id" type="varchar" required="true" />

   <behavior name="concrete_inheritance">
       <parameter name="extends" value="application" />
   </behavior>

</table>

<table name="application_identifier" phpName="IphoneApplicationIdentifier">

    <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" />
    <column name="application_id" required="true" type="integer" />
    <column name="identifier" type="varchar" required="true" primaryString="true" />

    <foreign-key foreignTable="application_iphone">
        <reference local="application_id" foreign="id" />                                 
    </foreign-key>     

</table>

The model builds correctly. The issue raises when I try to load the following fixtures:

Acme\MyBundle\Model\Application:
    first_app:
        name: "MyFirstApp"
        descendant_class: "IphoneApplication"

Acme\MyBundle\Model\IphoneApplication:
    first_app_iphone:
        id: first_app
        store_id: 2342

Acme\MyBundle\Model\IphoneApplicationIdentifier:     
    first_app_identifier:
        identifier: "com.acme.myfirstapp.appstore"
        application_id: first_app_iphone

The following error occurs:

[Propel] Exception
Cannot insert a value for auto-increment primary key (application.ID)

I added my "first_app" application twice (one in Application , another time in IphoneApplication ) to prevent from another issue with my IphoneApplicationIdentifier fixture:

[Propel] Exception The object "first_app" from class "Acme\\MyBundle\\Model\\Application" is not defined in your data file.

How can I insert fixtures for a concrete inheritant model?

Answer 1

Propel is telling you that you are trying to set a value for an autoincrement column, this is due to the

    id: first_app

line.

If I am understanding you correctly, you just want to add an Iphoneapplication item, is that right? If that is the case you just need to do:

Acme\MyBundle\Model\IphoneApplication:
    first_app_iphone:
        name: "MyFirstApp"
        store_id: 2342

I had similar situation and ended up with having different schema files. For testing one - I removed auto-increment from schema and defined another place for storing models. It was long time ago, but general steps were as below:

---

1. Dump fixtures for prod environment

    app/console propel:fixtures:dump 

2. Build everything you need for testing database

    app/console propel:database:create --env=test app/console propel:sql:build --env=test app/console propel:sql:insert --force --env=test app/console propel:model:build --env=test 

3. Imported fixtures into test database

    app/console propel:fixtures:load --env=test 

Note, that commands may vary depending on version of Propel

I found the mistake by explaining my problem in details. The issue did not come from this fixtures file. The error I had seemed strange to me. Why the error mentioned *first_app* instead of *iphone_first_app*?

After digging into the other fixtures files, I found a forgotten reference to *first_app*. The solution is simply the following (as mentioned by Carlos Granados):

Acme\MyBundle\Model\IphoneApplication:
    first_app_iphone:
        name: "My first app"
        store_id: 2342

Acme\MyBundle\Model\IphoneApplicationIdentifier:     
    first_app_identifier:
        identifier: "com.acme.myfirstapp.appstore"
        application_id: first_app_iphone

There is no need to define base class. :)
