Christian Weiske	fde7d7dde2	Elastic: Properly display sparse result rows Result records in Elasticsearch do not always have all columns that are defined in an index. This often happens when multiple document types are stored in the same index. The first row has columns ["_id", "html", "url"], while the second misses the "html" column: ["_id", "url"]. Adminer expects that all result rows include all columns. This leads to the problem that the "url" value in the 2nd example row was rendered in the "html" column. This patch fixes this problem by fetching the actual column list first when all fields are to be shown, and using that field list as base for all rows.	2025-03-10 21:14:54 +01:00
Christian Weiske	e993462412	Elastic: Fix record insertion on Elasticsearch 7 1. Make values NULLable by default, so that empty values do not get submitted to the Elasticsearch server. This helps e.g. with empty date fields - Elasticsearch would try to convert the field type to string when the value is an empty string, but that fails when there are documents with properly filled date fields 2. Remove _id from the POST array because this is not allowed. The server fails if it is included with > mapper_parsing_exception: > Field [_id] is a metadata field and cannot be added inside a document. > Use the index API request parameters. 3. Use the correct URL to create a document: "$index/_doc/" and "$index/_doc/$id". This is the same for ES 7 and 8: - https://www.elastic.co/guide/en/elasticsearch/reference/8.17/docs-index_.html#docs-index-api-request - https://www.elastic.co/guide/en/elasticsearch/reference/7.17/docs-index_.html#docs-index-api-request 4. Handle failed creations by checking for false 5. Return the "result" property string instead of the non-existing "created" property.	2025-03-10 21:13:16 +01:00
