无法放回 DesignDocuments

Question

我正在尝试从数据库中删除所有文档，但我想保留视图。所以我尝试了

//First, get all DesignDocument for the current database
List<DesignDocument> dbDesigns = cloudant.getDesignDocumentManager().list();

//Now, we delete the database           
cloudantClient.deleteDB(_DatabaseName);

            //now we create the database again
cloudant = cloudantClient.database(_DatabaseName, true);

//finally, try to add the DesignDocuments back
            if (dbDesigns != null && dbDesigns.size() > 0) {
                for (DesignDocument dDoc : dbDesigns) {
                    Response response = cloudant.getDesignDocumentManager().put(dDoc);
                    System.out.println(response);
                }
            }

但我在

处收到错误

Response response = cloudant.getDesignDocumentManager().put(dDoc);


java.lang.IllegalArgumentException: rev should be null

还有其他方法可以保留视图吗？

Answer 1

我怀疑出现此错误是因为在 dDoc 中设置了文档修订版属性 (_rev)。但是，由于在数据库中找不到具有匹配 id 的文档，因此 put 方法会引发错误。在调用 put

之前尝试使用 setRevision 方法将修订设置为 null

dDoc.setRevision(null);
Response response = cloudant.getDesignDocumentManager().put(dDoc);
