Hi, I'm working with SharePoint and ProjectServer 2007 via PSI with Python.

I can't find any documentation on how Filter Class (Microsoft.Office.Project.Server.Library) objects work internally to emulate its behaviour in Python.

Any ideas?

A: 

Take a look at Colby Africa's blog post. Also, msdn docs are here.

Edit

The generated filter is just XML. Here is a filter that returns the data from the "LookupTables" table (list of all the lookup tables):

<?xml version="1.0" encoding="utf-16"?>
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" filterTableName="LookupTables" xmlns="http://microsoft.com/ProjectServer/FilterSchema.xsd"&gt;
  <Fields>
    <Field tableName="" fieldName="LT_UID" />
    <Field tableName="" fieldName="LT_NAME" />
    <Field tableName="" fieldName="LT_SORT_ORDER_ENUM" />
    <Field tableName="" fieldName="LT_PRIMARY_LCID" />
    <Field tableName="" fieldName="LT_FILL_ALL_LEVELS" />
    <Field tableName="" fieldName="LT_CHECKOUTBY" />
    <Field tableName="" fieldName="LT_CHECKOUTDATE" />
    <Field tableName="" fieldName="MOD_DATE" />
  </Fields>
  <Criteria />
</Filter>

Here is another example of the filters required for getting all the data for one table...

Step 1: Get the row for the LookupTable (general table info)

<?xml version="1.0" encoding="utf-16"?>
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" filterTableName="LookupTables" xmlns="http://microsoft.com/ProjectServer/FilterSchema.xsd"&gt;
  <Fields>
    <Field tableName="" fieldName="LT_UID" />
    <Field tableName="" fieldName="LT_NAME" />
    <Field tableName="" fieldName="LT_SORT_ORDER_ENUM" />
    <Field tableName="" fieldName="LT_PRIMARY_LCID" />
    <Field tableName="" fieldName="LT_FILL_ALL_LEVELS" />
    <Field tableName="" fieldName="LT_CHECKOUTBY" />
    <Field tableName="" fieldName="LT_CHECKOUTDATE" />
    <Field tableName="" fieldName="MOD_DATE" />
  </Fields>
  <Criteria>
    <FieldOperator fieldOperationType="Equal">
      <Field fieldName="LT_UID" />
      <Operand xmlns:q1="http://microsoft.com/wsdl/types/" xsi:type="q1:guid">20870732-12b6-48e2-acf4-94d934dfc27a</Operand>
    </FieldOperator>
  </Criteria>
</Filter>

Step 2: Get all the data from the LookupTableStructures table (hierarchy info)

<?xml version="1.0" encoding="utf-16"?>
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" filterTableName="LookupTableStructures" xmlns="http://microsoft.com/ProjectServer/FilterSchema.xsd"&gt;
  <Fields>
    <Field tableName="" fieldName="LT_STRUCT_UID" />
    <Field tableName="" fieldName="LT_UID" />
    <Field tableName="" fieldName="LT_PARENT_STRUCT_UID" />
    <Field tableName="" fieldName="LT_STRUCT_COOKIE" />
  </Fields>
  <Criteria>
    <FieldOperator fieldOperationType="Equal">
      <Field fieldName="LT_UID" />
      <Operand xmlns:q1="http://microsoft.com/wsdl/types/" xsi:type="q1:guid">20870732-12b6-48e2-acf4-94d934dfc27a</Operand>
    </FieldOperator>
  </Criteria>
</Filter>

Step 3: Get all of the values in this lookup table

<?xml version="1.0" encoding="utf-16"?>
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" filterTableName="LookupTableValues" xmlns="http://microsoft.com/ProjectServer/FilterSchema.xsd"&gt;
  <Fields>
    <Field tableName="" fieldName="LT_STRUCT_UID" />
    <Field tableName="" fieldName="LCID" />
    <Field tableName="" fieldName="LT_UID" />
    <Field tableName="" fieldName="LT_VALUE_DUR" />
    <Field tableName="" fieldName="LT_VALUE_NUM" />
    <Field tableName="" fieldName="LT_VALUE_DUR_FMT" />
    <Field tableName="" fieldName="LT_VALUE_DATE" />
    <Field tableName="" fieldName="LT_VALUE_TEXT" />
    <Field tableName="" fieldName="LT_VALUE_PHONETIC" />
    <Field tableName="" fieldName="LT_VALUE_FULL" />
    <Field tableName="" fieldName="LT_VALUE_DESC" />
    <Field tableName="" fieldName="LT_VALUE_SORT_INDEX" />
    <Field tableName="" fieldName="LT_VALUE_LOCALIZED_COOKIE" />
  </Fields>
  <Criteria>
    <FieldOperator fieldOperationType="Equal">
      <Field fieldName="LT_UID" />
      <Operand xmlns:q1="http://microsoft.com/wsdl/types/" xsi:type="q1:guid">20870732-12b6-48e2-acf4-94d934dfc27a</Operand>
    </FieldOperator>
  </Criteria>
</Filter>

It requires three separate filters to get all this data because it is split across three separate tables. In C#, I am calling the ReadLookupTablesMultiLang function with each of these filters and then merging the returned datatables.

The problem here is that I don't have all these methods to build a Filter object (I am using Python). I think the best solution for me could be to see the syntax of the final XML sent in the HTTP request and generate something similar from Python.

I've updated my answer to include the XML that is generated from an example when working with LookupTables. Let me know if that helps!
Kit Menke
Yeah! That's what I need! Now I'll try to generate the right query from Python. Thanks a lot!
