问题 HI I'm new to cloudant (and couch and asking questions on stackoverflow so I hope I manage to be vaguely clear about what I'm asking ) and I'm trying to do probably the second most basic geo task but am hitting a dead end. I've got a database of docs which are geojson objects, I've created an index so I can query for intersections etc but it seems the only options I have in the url is the format=legacy (gives me the ids) and the format=geojson and the include_docs parameter - what I'd like to

问题 I'm collecting temperatures in CouchDB and would like to query for the average temperature by room, year, month, day, hour. Unfortunately, when I execute my query (see below) I'm getting all months, not just the month I specify in my query. However, if I specify just a single room I get only the month I specify in my query. How do I query all rooms for just a specified period? Map Function: function(doc) { if(doc.type == "TempHumid"){ var d = new Date(doc.datetime); for(var i in doc.path)

问题 I have CORS issue between UI and couchdb. But in couchdb CORS is enabled, and UI has res.header("Access-Control-Allow-Origin", "*"); header. But I still have an error XMLHttpRequest cannot load http://localhost:5984/cp_display_template/. A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'http://localhost' is therefore not allowed access. The credentials mode of an XMLHttpRequest is controlled by the withCredentials attribute.

问题 The code is smaller version I put together to demonstrate what I am trying to do. I just need to get information from a QButtonGroup of radio buttons. Specifically the text of which one has been clicked. However, when I run click the button in the GUI python crashes. There is no error message so I can't pinpoint the cause. Below is the example code, below that is the image show upon clicking a radio button: Working earlier with a more inefficient method I got to sending commands to the server

问题 I have simple Angular app, which can perform some requests over $http to remote service (couchdb) at example.com/.../myservice . Service requires auth, which done by calling specified address example.com/_session with name and password and it returns with session cookie AuthSession . Problem is that cookie is not used when calls to service is done. Maybe problem caused because cookie is per-session Http-only (and that's can't be changed). I think the solution is grabbing cookie from auth

问题 I have a few documents in my couch db with json as below. The cId will change for each.
