無法爲沒有主鍵的模型生成模塊

Question

我有一個標題表/模型，並且我還有一個「標題」模塊。當我去標題模塊，這在過去一直很好，現在給了我這個錯誤：

Cannot generate a module for a model without a primary key (Heading) 

這是奇怪的我，因爲我對標題的schema.yml看起來是這樣的：

Heading: 
    connection: doctrine 
    tableName: heading 
    columns: 
    id: 
     type: integer(8) 
     fixed: false 
     unsigned: false 
     primary: true 
     autoincrement: true 
    referenced_table_name: 
     type: string(255) 
     fixed: false 
     unsigned: false 
     primary: false 
     notnull: true 
     autoincrement: false 
    column_name: 
     type: string(255) 
     fixed: false 
     unsigned: false 
     primary: false 
     notnull: true 
     autoincrement: false 
    label: 
     type: string(255) 
     fixed: false 
     unsigned: false 
     primary: false 
     notnull: true 
     autoincrement: false 
    position: 
     type: integer(4) 
     fixed: false 
     unsigned: true 
     primary: false 
     notnull: true 
     autoincrement: false 
    import_profile_id: 
     type: integer(8) 
     fixed: false 
     unsigned: false 
     primary: false 
     notnull: true 
     autoincrement: false 
    note: 
     type: string() 
     fixed: false 
     unsigned: false 
     primary: false 
     notnull: true 
     autoincrement: false 
    created_at: 
     type: timestamp(25) 
     fixed: false 
     unsigned: false 
     primary: false 
     default: '0000-00-00 00:00:00' 
     notnull: true 
     autoincrement: false 
    updated_at: 
     type: timestamp(25) 
     fixed: false 
     unsigned: false 
     primary: false 
     default: '0000-00-00 00:00:00' 
     notnull: true 
     autoincrement: false 
    relations: 
    ImportProfile: 
     local: import_profile_id 
     foreign: id 
     type: one 
    TotalFromFile: 
     local: id 
     foreign: heading_id 
     type: many 

注意主鍵：

columns: 
    id: 
     type: integer(8) 
     fixed: false 
     unsigned: false 
     primary: true 
     autoincrement: true 

我懷疑它是與this other problem I'm having。有任何想法嗎？

原來的問題是我已經定義了HeadingTable::getTables()和HeadingTable::getColumns()。學說不喜歡那樣。
