Question

I’m using NHibernate with C# and at compiling time it gives me this error:

 {"Could not find a getter for property 'idOrder' in class 'FrancosPoS.DBMapping.ordPsf'"}

I have found this question, but I could not get how to use it for me:
Nhibernate – Could not find a getter for property

This is my mapping class:

<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping assembly="FrancosPoS" namespace="FrancosPoS.DBMapping" xmlns="urn:nhibernate-mapping-2.2">
  <class name="ordPsf" table="ord_psf" lazy="true" >
    <id name="idOrdPastaF">
      <generator class="identity" />
      <!--<column name="idOrdPastaF" sql-type="int(11)" not-null="true" />-->
    </id>
    <many-to-one insert="false" update="false" lazy="false" name="idOrder">
      <column name="idOrder" sql-type="int(11)" not-null="true" />
    </many-to-one>
    <property name="idOrder">
      <column name="idOrder" sql-type="int(11)" not-null="true" />
    </property>
    <many-to-one insert="false" update="false" lazy="false" name="idPastaF">
      <column name="idPastaF" sql-type="int(11)" not-null="true" />
    </many-to-one>
    <property name="idPastaF">
      <column name="idPastaF" sql-type="int(11)" not-null="true" />
    </property>
    .
    .
    .
    <property name="obs">
      <column name="obs" sql-type="varchar(50)" not-null="false" />
    </property>
    <property name="price">
      <column name="price" sql-type="decimal(8,4)" not-null="true" />
    </property>
  </class>
</hibernate-mapping>

And this is my cs class:

namespace FrancosPoS.DBMapping {

    public partial class ordPsf {
        public ordPsf() { }
        public virtual int idOrdPastaF { get; set; }
        public virtual order order { get; set; }
        public virtual pastaFeast pastaFeast { get; set; }
        public virtual salad salad { get; set; }
        public virtual onTheSide onTheSide { get; set; }
        public virtual string obs { get; set; }
        public virtual string price { get; set; }
    }
}

My guess is that I’m doing the mapping wrong. By obvious reasons, I don’t want to have a idOrder get/set because I need to use the object. (Besides, I’m guessing that the same error will occur at the other ids after fixing this one)

Answer 1

I have found that the problem is with the < property > “conflicting” with the < many-to-one > relationship:

<property name="idOrder">
  <column name="idOrder" sql-type="int(11)" not-null="true" />
</property>

We don’t need to have this as the many-to-one will take care of the order object (and id).
