I work with symfony2 and there i use doctrine. As Example i have a simple repository-class in my doctrine xml-file:
<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
<entity name="AllgemeinBundle\Entity\ObjektPosition" table="objekt_position" repository-class="AllgemeinBundle\Repository\ObjektPositionRepository">
<indexes>
<index name="id_objekt_subunternehmer_position_fk2_idx" columns="id_subunternehmer"/>
<index name="id_objekt_objektposition_idx" columns="id_objekt"/>
</indexes>
<id name="id" type="integer" column="id">
<generator strategy="IDENTITY"/>
</id>
<field name="artikelnummer" type="integer" column="artikelnummer" nullable="false"/>
<field name="preisProEinheit" type="float" column="preis_pro_einheit" precision="10" scale="2" nullable="false"/>
<field name="p1Einheit" type="float" column="p1_einheit" precision="10" scale="2" nullable="false"/>
<field name="p2Einheit" type="float" column="p2_einheit" precision="10" scale="2" nullable="true"/>
<field name="p3Einheit" type="float" column="p3_einheit" precision="10" scale="2" nullable="true"/>
<field name="zusatztext" type="text" column="zusatztext" nullable="true"/>
<field name="position" type="integer" column="position" nullable="false"/>
<many-to-one field="idSubunternehmer" target-entity="Subunternehmer">
<join-columns>
<join-column name="id_subunternehmer" referenced-column-name="subunternehmernummer"/>
</join-columns>
</many-to-one>
<many-to-one field="idObjekt" target-entity="Objekt">
<join-columns>
<join-column name="id_objekt" referenced-column-name="id"/>
</join-columns>
</many-to-one>
when i am generating my entities from the database, then the repository-class would be deleted. Also some other thinks i added to the xml-file.
Is it able to save the customized data in a sperated folder or file, so that i can generate the entities as often as i like and the customized data wouldn't be lost?
If you are using console commands, when generating entities don't mention '--no-backup' at the end of the command. So, you will be able to preserve your entity class. However you entity class will be renamed with adding '~' sign at the start of the file name. Your entity generation code will be like this, (without trailing --no-backup)
php app/console doctrine:generate:entities
Hope this helps,
Cheers!

as far as I understand I need to add a "cascade" parameter to the mapping. But my mapping is in XML.
I found quite a bit of information about it but there was no result.
Pleace help!
Мy error is:
Multiple non-persisted new entities were found through the given association graph:\n\n * A new entity was found through the relationship 'Domain\Maintenance\Maintenance#affectedRegions' that was not configured to cascade persist operations for entity: Domain\AffectedRegion\AffectedRegion#0000000075384ba200000000535ab7f1. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example #ManyToOne(..,cascade={"persist"}). If you cannot find out which entity causes the problem implement 'Domain\AffectedRegion\AffectedRegion#__toString()' to get a clue.\n *
XML fails:
<entity name="Domain\Maintenance\Maintenance" table="maintenances" repository-class="Infrastructure\Repositories\MaintenanceRepository">

this is my FK:
$affectedRegionTable->addForeignKeyConstraint(
$regionTable,
['region_id'],
['id'],
['onUpdate' => 'CASCADE'],
'fk_affectedRegions_region_id'
);
$affectedRegionTable->addForeignKeyConstraint(
$regionTable,
['maintenance_id'],
['id'],
['onUpdate' => 'CASCADE'],
'fk_affectedRegions_maintenance_id'
);
the relation I want to make is:
Maintenance ← one-to-many → AffectedRegions ← many-to-one → Region
Here is the answer.
Another way to add a cascade argument:
<one-to-many field="affectedRegions" target-entity="Domain\AffectedRegion\AffectedRegion" mapped-by="maintenance">
<cascade>
<cascade-persist/>
<cascade-remove/>
</cascade>
</one-to-many>
Solr Version : 5.0
So I am working on Solr for first time, and really not understand perfectly. Here what I did :-
I have created a core named - search
Then my schema.xml file has follwoing code :
<?xml version="1.0" encoding="UTF-8" ?>
<schema name="simple" version="1.5">
<types>
<fieldtype name='string' class='solr.StrField' />
<fieldtype name='long' class='solr.TrieLongField' />
</types>
<fields>
<field name='id' type='int' required='true' indexed="true"/>
<field name='name' type='text' required='true' indexed="true"/>
</fields>
<uniqueKey>id</uniqueKey>
<defaultSearchField>fullText</defaultSearchField>
<solrQueryParser defaultOperator='OR' />
</schema>
solrconfig.xml :
<?xml version='1.0' encoding='UTF-8' ?>
<config>
<luceneMatchVersion>5.0.0</luceneMatchVersion>
<lib dir="../../../../dist/" regex="solr-dataimporthandler-.*\.jar" />
<requestHandler name="standard" class="solr.StandardRequestHandler" default='true' />
<requestHandler name="/update" class="solr.UpdateRequestHandler" />
<requestHandler name="/admin/" class="org.apache.solr.handler.admin.AdminHandlers" />
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">db-data-config.xml</str>
</lst>
</requestHandler>
<admin>
<defaultQuery>*:*</defaultQuery>
</admin>
</config>
db-data-config.xml :
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/solr"
user="root"
password="" />
<document>
<entity name="users" query="select id,name from users;" />
</document>
</dataConfig>
I have created a database on PHPmyadmin please find below SG :
when I clicked query on solr panel then it shows empty why ?
Can anyone help me on this, as I am new to solr search. What I am doing wrong ?
I dont see a field named "fulltext" in schema.xml but why its defined as the default search
<defaultSearchField>fullText</defaultSearchField>
change it
<defaultSearchField>name</defaultSearchField>
mention the fields in the data config xml
<field column="ID" name="id" />
<field column="NAME" name="name" />
your data-config should look alike
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/solr"
user="root"
password="" />
<document>
<entity name="users" query="select id,name from users">
<field column="ID" name="id" />
<field column="NAME" name="name" />
</entity>
</document>
</dataConfig>
add it as in schema.xml
<types>
<fieldType name="string" class="solr.StrField" sortMissingLast="true" omitNorms="true"/>
<fieldType name="int" class="solr.TrieIntField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
</types>
<fields>
<field name='id' type='int' required='true' indexed="true" stored="true"/>
<field name='name' type='string' required='true' indexed="true" stored="true"/>
<fields>
Make the changes in your db-data-config.xml similar to what i have done
<entity name="city_masters" pk="city_id" query="SELECT delete_status as
city_masters_delete_status,city_id,country_id,city_name,city_updated from
city_masters>
<field column="city_id" name="id"/>
<field column="city_name" name="city_name" indexed="true" stored="true" />
<field column="country_id" name="country_id" indexed="true" stored="true" />
<field column="city_masters_delete_status" name="city_masters_delete_status"
indexed="true" stored="true" />
</entity>
You missed out the field column part.Add them like i have done for my code and it should work.If still doesnt work let me know
I start to model the db/entities in symfony2.
I have two entities. First is a User and second is a Groups.
I want to connect both. I think I should use many to many relations(?).
But my major problem is how can I get list of all groups with information if user joined this group.
Group Entity:
<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
<entity name="GroupBundle\Entity\Group">
<id name="id" type="integer" column="id">
<generator strategy="AUTO"/>
</id>
<field name="name" type="string" column="name" length="50"/>
<field name="description" type="string" column="description"/>
<many-to-many field="users" mapped-by="groups" target-entity="AccountBundle\Entity\User"/>
</entity>
</doctrine-mapping>
and User Entity:
<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
<entity name="AccountBundle\Entity\User">
<id name="id" type="integer" column="id">
<generator strategy="AUTO"/>
</id>
<field name="username" type="string" column="username" length="255"/>
<field name="password" type="string" column="password" length="255"/>
<field name="salt" type="string" column="salt" length="255"/>
<field name="email" type="string" column="email" length="255"/>
<field name="active" type="boolean" column="active"></field>
<field name="token" type="string" column="token" length="255"/>
<field name="lastLoginTime" type="datetime" column="lastLoginTime" nullable="true"/>
<field name="registerTime" type="datetime" column="registerTime"/>
<one-to-many field="events" target-entity="CoreBundle\Entity\Event" mapped-by="user" />
<many-to-many field="groups" inversed-by="users" target-entity="GroupBundle\Entity\Group">
<join-table name="UserGroups">
<join-columns>
<join-column name="userId" referenced-column-name="id" />
</join-columns>
<inverse-join-columns>
<join-column name="groupId" referenced-column-name="id" />
</inverse-join-columns>
</join-table>
</many-to-many>
</entity>
</doctrine-mapping>
There is no relation between there yet because I don't know what is best.
Maybe I must create additional Entity between like UserGroup?
D4V1D you have a right. Assumption is: User can join to many group and group can have a many user.
Okey I add the many-to-many relations. I hope I did it right.
And now. This is fragment of my controller:
$em = $this->getDoctrine()->getManager();
$repo = $em->getRepository("GroupBundle\Entity\Group");
$groups = $repo->findAll();
$user = $this->getUser();
$user_groups = $user->getGroups();
foreach($user_groups as $user_group){
/* #var $group Group */
foreach($groups as $group){
if($group->getId() == $user_group->getId()){
$group->setUserInGroup(true); // of course i extend my entity file about extra set and get method.
}
}
}
return $this->render('GroupBundle:showAll.html.twig', array('groups' => $groups));
and view:
{% for group in groups %}
<div>
{{ group.name }}
{% if(group.getUserInGroup()) %}
join
{% endif %}
</div>
{% endfor %}
I try find the best and right method to do this.
Without relation OneToMany with user and group, how do you join the group with user? which field have this information? you need a relation yes.
Group entity :
<many-to-many field="users" target-entity="AccountBundle\Entity\User" mapped-by="groups" />
User entity :
<many-to-many field="groups" target-entity="GroupBundle\Entity\Group" inversed-by="users"/>
I have created an index that pulls data from a SQL Server database using TikaEntityProcessor. The query associated with my configuration file pulls from a table containing file information, as well as the file content as a binary column. My index returns all fields from the database table in which I have configured, as well as the column for "text" that is the body of the file content. It correctly indexes the file text! However, the meta columns are not working! You can see I have a field for text/body, this works fine. However, I cannot get any metadata from the file such as last modified date or author.
Any suggestions would be greatly appreciated!!
data-config:
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://server;databaseName=db1;integratedSecurity=false"
user="user"
password="XXXXXX" convertType="false"
name="ds"/>
<dataSource name="fieldReader"
type="FieldStreamDataSource" />
<document name="tika">
<entity name="tika" pk="id" transformer="TemplateTransformer" dataSource="ds"
query="select id, title from myDatabaseTable">
<entity name="tika-test" processor="TikaEntityProcessor" dataSource="fieldReader"
dataField="tika.FileContent" format="text">
<field column="text" name="body"/>
<field column="Last-Modified" name="lastModified" meta="true" /> <!-- not working -->
</entity>
</entity>
</document>
</dataConfig>
schema:
<field name="id" type="integer" indexed="true" stored="true" />
<field name="body" type="text" indexed="true" stored="true" />
<field name="lastModified" type="text" indexed="true" stored="true" />
<field name="title" type="text" indexed="true" stored="true" />
Thanks!!
I'm trying to update my doctrine schema with the command:
php app/console doctrine:schema:update --force
I'm getting this error:

Is the type of the field "file" missing?
