Re: [QGIS-it-user] join tra tabelle

[Matteo Collimedaglia]

Esatto, per quello ho creato un campo ID, che mi permettesse di risolvere
questo problema. Con il campo ID, inserisco un numero che sarà sempre
diverso.

Grazie,
Matteo

Thanks.
I fixed the problem by deleting directory C:\OSGeo4W64, and reinstalling
QGIS version 2.18.14

Re: [QGIS-it-user] join tra tabelle

[G. Allegri]

Ciao Matteo,
scusa ma non ho capito il tuo problema. Che tipo di join devi fare? Le due
tabelle avranno un campo in comune, ed è normale che, in un classico join
1:N, tu abbia più righe (in una tabella) che puntano alla stessa riga
(nell'altra). Ad esempio un potresti avere un layer circoscrizioni in join
con una tabella delle città.

Re: [QGIS-it-user] campo tipo numero intero lunghezza 10 QGIS 2.16 e 2.18

[Gabriela Osaci Costache]

Ciao!
Ho provato ad usare un vettore SpatiaLite (tipo linea). Con la versione 2.18.14 
e con quella di sviluppo il campo di tipo numero intero con una lunghezza di 10 
è visto come "qlonglong  - integer" (con uno strato .shp è visto "qlonglong - 
integer64") e l'interpolazione (TIN) non si fa.
Usando un .shp si ottiene lo stesso errore anche con la versione di sviluppo 
(aggiornata ieri). Dunque aggiungiamo anche questa versione sulla "lista nera".
Saluti e grazie,Gabriela

Re: [Qgis-user] script filegdb to spatial lite

[Alex M]

Matt,

Each layer is a separate table within the database, you can have as many
as you like. As with most spatial formats I would avoid mixed geometries
in the same layer.

Here are some of the docs about spatialite
https://www.gaia-gis.it/fossil/libspatialite/wiki?name=misc-docs
https://www.gaia-gis.it/fossil/libspatialite/index

Enjoy,
Alex

Hi,

I´m new to this support list, and would like to post a question.

I´m developing a QGIS Python plugin. The plugin loads in one computer but not 
in another (both with Windows 10). I get this message in the wrong one:

This plugin is broken
Error reading metadata: global name '__builtin__' is not defined

In the computer that gives the error message I have the latest QGIS version:

QGIS version

​The one that runs OK has version 2.18.3

​Any idea of what is happening?

QGIS can help you calculate these information automatically, without using
the Measure tool and report its values manually. Use the $area or
$perimeter/$length functions from the field calculator (see doc at
http://docs.qgis.org/2.18/en/docs/user_manual/working_with_vector/attribute_table.html#field-calculator).
Matthias answer uses these functions automatically at creation but you can
process the calculation any time, in one-click.

Re: [Qgis-user] vector digitizing question

[Tudorache, Marian]

Hi Scott,

The new possibility in 2.18 is cool but if you have older QGIS version you can 
use SIGNAL/SLOTS

.featuresAdded().connect(defaultAttributes)

def defaultAttributes(fid):
feature = [feat for feat in .getFeatures() if feat.id() == fid][0]
.changeAttributeValue(fid, , 
feature.geometry().length())
.featuresAdded().disconnect()

It is a little bit messy :).

[Qgis-user] vector digitizing question

[Madry, Scott]

Hello all. I have a vector polygon shape file that was originally created in 
ArcGIS. I have recently added three polygons to the file using QGIS, but the 
results (attached) show that the area and perimeter values for these are not 
computed. How can I, in QGIS, generate these area and perimeter fields to be 
added? I know I can manually do the areas using the ‘Measure’ tool, but would 
prefer an automated process. Does Arc just create these automatically? Can QGIS?

Thanks so much,

Scott
