I haven't seen the exactly question before. Sorry if there are a similar question yet.This is my idea. I have a QGIS project where there are plots with a atttributes like name of the owner, address of the owner, cultivate...and so on.This plots are read from a PostGIS database. The future users of this project are not user of QGIS and is not an option to teach them things like "Go into properties->fields calculators...etc".Then, they only need to use things like selections by name of the owner, or cultivate of the plot, town of the plot ..and show the plots with this attributes.I can make a dialog form in Qt and create a postgres(postGIS) view from the selects fields, but I don't know how can QGIS refresh or read the created views.I don't know if this is a properly approach for solve that question.Thanks in advanced and sorry for my english.
