QuickFinder QGIS plugin generates python errors

Question

I have had no success setting up the QuickFinder plugin in QGIS to search project layers. Once I select the checkbox "Search in project layers" in the settings and create a new QuickFinder file, it gives the following error when trying to create a search.

I had the same errors on a Win7 (QGIS 2.10.1) and Ubuntu machine (QGIS 2.8.1). I uninstall/reinstalled the plugin, and I also installed from the extracted zip file without any luck.

Any ideas how to get this plugin up and running on QGIS 2.10?

An error has occured while executing Python code:

Traceback (most recent call last): File "C:/Users/username/.qgis2/python/plugins\quickfinder\gui\projectsearchdialog.py", line 78, in process ok, message = self.projectFinder.recordSearch(self.projectSearch) File "C:/Users/username/.qgis2/python/plugins\quickfinder\core\projectfinder.py", line 230, in recordSearch self.deleteSearch(searchId, False) File "C:/Users/username/.qgis2/python/plugins\quickfinder\core\projectfinder.py", line 197, in deleteSearch cur.execute(sql) OperationalError: no such table: quickfinder_data

Answer 1

The error is OperationalError: no such table: quickfinder_data in the file projectfinder.py.
If you look at the Python source code, you discover that, when you create a SQLite Database, quickfinder_data is a Sqlite Virtual Table (file projectfinder.py)

def createFTSfile(filepath):
    conn = sqlite3.connect(filepath)
    sql = "CREATE TABLE quickfinder_info (key text,value text);"
    sql += "INSERT INTO quickfinder_info (key,value) VALUES ('scope','quickfinder');"
    sql += "INSERT INTO quickfinder_info (key,value) VALUES ('db_version','1.0');"
    sql += "CREATE TABLE quickfinder_toc (search_id text, search_name text, layer_id text, layer_name text, expression text, priority integer, srid text, date_evaluated text);"
    sql_unicode61 = sql + "CREATE VIRTUAL TABLE quickfinder_data USING fts4 (tokenize=unicode61 \"remove_diacritics=1\", search_id, content, x real, y real, wkb_geom text);"
    sql += "CREATE VIRTUAL TABLE quickfinder_data USING fts4 (search_id, content, x real, y real, wkb_geom text);"
    cur = conn.cursor()
    try:
         cur.executescript(sql_unicode61)
    except sqlite3.OperationalError:
         cur.executescript(sql)
    conn.close()

And that the connection to the database is closed (conn.close())

To use it, you need to first push the refresh button (to reopen the connection, Quickfinder does not automatically refresh) but look also at How to setup FTS3/FTS4 with python2.7 on Windows which may pose problems
