问题 I'm new to RavenDB, and am loving it so far. I have one remaining index to create for my project. The Problem I have thousands of responses to surveys (i.e. " Submissions "), and each submission has an array of answers to specific questions (i.e. " Answers "), and each answer has an array of options that were selected (i.e. " Values "). Here is what a single Submission basically looks like: { "SurveyId": 1, "LocationId": 1, "Answers": [ { "QuestionId": 1, "Values": [2,8,32], "Comment": null }

问题 I'm trying to update the entire collection by adding an extra field to each entity. This doesn't do the trick: from things as t update { put( id(t), "NewField"); } Can someone help out with the syntax please ? Thanks ! 回答1: Just do: from things as t update { t.nameOfNewField = "valueOfNewField" } See: https://ravendb.net/learn/inside-ravendb-book/reader/4.0/2-zero-to-ravendb#patching-documents 来源： https://stackoverflow.com/questions/60413448/add-extra-column-field-to-ravendb-collection-via

问题 Please I am using the default ID Generation in raven DB inserting and everything seems to work fine for now However My ID Has the following format "entityName/1" so if added as a route value, the following URL Results http://localhost:10563/Settings/Edit/SystemSettings/1 Which as u can guess results in the following message Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please

问题 I got the following comment to my previous question about RavenDb: One thing to note, QueryYourWrites doesn't work with Map/Reduce indexes. For these you have to use WaitForNonStaleResults..() What does it mean? I thought all indexes in RavenDb are Map/Reduce indexes... In which cases does QueryYourWrites option work? 回答1: Sorry, I wrote that comment and I wasn't very clear. RavenDB indexes always need to have a Map part, but the Reduce is optional.
