<div dir="ltr">Hello,<div>I am having trouble utilizing the <span style="background-color:transparent;font-family:ui-monospace,SFMono-Regular,"SF Mono",Menlo,Consolas,"Liberation Mono",monospace;color:rgb(36,41,47);font-size:11.9px">QgsVectorFileWriter.create() method. I am not getting any errors but no layer is being created. I am trying to write a geopackage layer. I know my QgsFields are correct because I have used them for some other code previously. Should the driver name be "ogr" or "gpkg"? Is there any sort of commit statement that needs to happen after creation? Or is creation predicated upon adding features? The only example I can find is here: </span><a href="https://github.com/qgis/QGIS/issues/35021">https://github.com/qgis/QGIS/issues/35021</a>.</div><div><span style="background-color:transparent;font-family:ui-monospace,SFMono-Regular,"SF Mono",Menlo,Consolas,"Liberation Mono",monospace;color:rgb(36,41,47);font-size:11.9px"><br></span></div><div><div style="color:rgb(212,212,212);background-color:rgb(30,30,30);font-family:Consolas,"Courier New",monospace;font-size:16px;line-height:22px;white-space:pre"><div> <span style="color:rgb(156,220,254)">qgsFields</span> = <span style="color:rgb(78,201,176)">QgsFields</span>()</div><div> <span style="color:rgb(156,220,254)">uploadLayerName</span> = <span style="color:rgb(86,156,214)">f</span><span style="color:rgb(206,145,120)">"</span><span style="color:rgb(86,156,214)">{</span><span style="color:rgb(156,220,254)">self</span>.<span style="color:rgb(156,220,254)">locationTypeText</span><span style="color:rgb(86,156,214)">}</span><span style="color:rgb(206,145,120)">-Upload-</span><span style="color:rgb(86,156,214)">{</span><span style="color:rgb(156,220,254)">self</span>.<span style="color:rgb(156,220,254)">layerDate</span><span style="color:rgb(86,156,214)">}</span><span style="color:rgb(206,145,120)">"</span></div><div> <span style="color:rgb(197,134,192)">for</span> <span style="color:rgb(156,220,254)">fieldMap</span> <span style="color:rgb(197,134,192)">in</span> <span style="color:rgb(156,220,254)">self</span>.<span style="color:rgb(156,220,254)">fieldMaps</span>:</div><div> <span style="color:rgb(156,220,254)">qgsFields</span>.<span style="color:rgb(220,220,170)">append</span>(</div><div> <span style="color:rgb(78,201,176)">QgsField</span>(<span style="color:rgb(156,220,254)">fieldMap</span>.<span style="color:rgb(156,220,254)">location_type_param_name</span>, <span style="color:rgb(156,220,254)">fieldMap</span>.<span style="color:rgb(156,220,254)">qvariantType</span>))</div><div> <span style="color:rgb(156,220,254)">options</span> = <span style="color:rgb(78,201,176)">QgsVectorFileWriter</span>.<span style="color:rgb(78,201,176)">SaveVectorOptions</span>()</div><div> <span style="color:rgb(156,220,254)">options</span>.<span style="color:rgb(156,220,254)">driverName</span> = <span style="color:rgb(206,145,120)">"ogr"</span></div><div> <span style="color:rgb(156,220,254)">options</span>.<span style="color:rgb(156,220,254)">layerName</span> = <span style="color:rgb(156,220,254)">uploadLayerName</span></div><div> <span style="color:rgb(156,220,254)">uploadWriter</span> = <span style="color:rgb(78,201,176)">QgsVectorFileWriter</span>.<span style="color:rgb(220,220,170)">create</span>(<span style="color:rgb(86,156,214)">f</span><span style="color:rgb(206,145,120)">"</span><span style="color:rgb(86,156,214)">{</span><span style="color:rgb(79,193,255)">GPKG_PATH</span><span style="color:rgb(86,156,214)">}</span><span style="color:rgb(215,186,125)">\\</span><span style="color:rgb(86,156,214)">{</span><span style="color:rgb(156,220,254)">uploadLayerName</span><span style="color:rgb(86,156,214)">}</span><span style="color:rgb(206,145,120)">"</span>, <span style="color:rgb(156,220,254)">qgsFields</span>, <span style="color:rgb(156,220,254)">self</span>.<span style="color:rgb(156,220,254)">layerGeometry</span>, <span style="color:rgb(78,201,176)">QgsCoordinateReferenceSystem</span>(</div><div> <span style="color:rgb(206,145,120)">"EPSG:4326"</span>), <span style="color:rgb(79,193,255)">TRANSFORM_CONTEXT</span>, <span style="color:rgb(156,220,254)">options</span>)</div></div></div><div><span style="background-color:transparent;font-family:ui-monospace,SFMono-Regular,"SF Mono",Menlo,Consolas,"Liberation Mono",monospace;color:rgb(36,41,47);font-size:11.9px"></span><div><br></div><div><br></div><div>Thank you.</div>-- <br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">
