 There is also the option of using the SQLite3  qgis.db which gets
 installed into every users ~/.qgis/ directory.

Hi,

that's true, however access to this database is not encapsulated by
QGIS API so far, thus it would be a bit rough to use...

Re: [Qgis-user] shape file

Hi

Yes I think my patch will check both before and after. Don't worry
about your English I can understand you fine :-)

 Hi

 Tim, now I know what problem was - it's absence of attributes of
 column. Then project has created somebody and did't fill up key - field.
 Qgis crashed because one field of one of objects was
 empty.
 I think that will be more better create a check of type field before
 creating a shape-file.

 P.S. sorry for my bad english, i hope you will understand me).


  Hi

  Looking at the code, only int, string and double types are currently
  supported. What data types are in your grass layer attributes table?
  Certainly we should not assert there but rather give some kind of
  feedback.

  Currently the code for QGIS 0.9.1 is in string freeze so I cant do
  much about it right now. However I have made a patch to at least just
  give an error message rather than assert (which causes the app to
  terminate).

  I have created a bug for this here:

  https://svn.qgis.org/trac/ticket/854

  Which includes a patch which at least prevents the app terminating. If
  you supply me with more info regarding the datatypes in your attribute
  table I will try to include support for additional dataypes in the
  above patch. As I recall shapefile format supports only int, double
  and string so any other attribute types will need to be merged into
  one of those types. I will apply the patch post 0.9.1 release.

  Regards

  Tim

  Hi
 
  I have a problem with generating shape file in qgis.
  When at grass vector layer I press right mouse button and select save as
  shapefile qgis crashes and in terminal appears this text:
  -
 
  QgsGrass::vectors()
  qgis: 
  /home/timlinux/dev/cpp/qgis-0.9.0/src/core/qgsvectorfilewriter.cpp:222: bo
  ol QgsVectorFileWriter::addFeature(QgsFeature): Assertion `0  invalid 
  varian
  t type' failed.
  Aborted
 
  -
 
  Somebody did such operation (i need to transport grass vector layer to
  postgis table in postgres)
