Re: [Qgis-user] Copy field definitions from one vector layer to another?

[Luca Lanteri]

ok, you are right.

You can import your shapfiles into spatialite using dbmanager, then copy
the definitions of the first layer, add column to the other layer and then
export to shapefile.

Re: [Qgis-user] Copy field definitions from one vector layer to another?

[Damien Stephens]

You can change the prefix of the column names in 2.10 there is a tick box  in 
the join dialog. not sure if you can set it to blank, but might work?

The join works without a common field of any kind, which is what I wanted, but 
unfortunately the field names get prefixed with the join layer.   When I export 
as shape file from the joined layer, I get field names like 'exported', 
'exported_1', etc.   So I don't think the join will work, since what I want to 
do is preserve field names, just copying them from one layer to another.
Maybe some other approach?   I was hoping for an existing plug-in, but have not 
found anything in the repository.   Maybe a python script to export field names 
from existing layer?  I will explore that approach, although I am not very 
familiar with python scripting for QGIS, see if I can get started.
Thanks.

[Luca Lanteri]

why do you need the same geometry type in order to make a join ?
You just need one common field.

On second reading of what you are looking for, The Table Manager plugin, 
may not be what you need.

Re: [Qgis-user] Copy field definitions from one vector layer to another?

[Goyo]

This might work:

1. Make an empty copy of the layer with the attributes.
2. Select all objects of the layer with the geometries.
3. Copy and paste the selected objects into the empty layer.

Yes, it was just an outline of the procedure. There may be some issues
to work around, depending on the details.

uhmm... well thought! This will probably work if the geometry types of both

[Qgis-user] Copy field definitions from one vector layer to another?

[Richard Males]

I have been looking for a capability (plugin or native QGIS) that will
easily copy the field definitions (not the attribute data) from one layer
to another layer.   To date I have not found it, I may be missing something
obvious.  Any help/advice much appreciated.

I have a layer with a bunch of fields already defined, and another layer
with geometry but no additional fields.   I would like to add the field
definitions from the first layer to the second layer, and then populate
with the appropriate data for that layer.
