#3528: v.random restrict join attributes
--------------------------------------------+-------------------------
Reporter: martinl | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: normal | Milestone: 7.4.1
Component: Vector | Version: unspecified
Keywords: v.random, restrict, attributes | CPU: Unspecified
Platform: Unspecified |
--------------------------------------------+-------------------------
Currently G7:v.random with `restrict` parameter transfers categories (if
`layer` > 0) but not attributes itself.
{{{
#v.random out=test n=5 --o restrict=geology layer=1
$ v.category test opt=print
28/1
450/2
28/3
21/4
28/5
$ v.db.select test
ERROR: Database connection not defined for layer <1>
}}}
Categories allows user to join attributes but it's quite tricky. This
ticket suggests to join attributes automatically.
{{{
$ v.random out=test n=5 --o restrict=geology layer=1
$ v.db.select test
cat|geology_cat|geology_onemap_pro|geology_PERIMETER|geology_GEOL250_|geology_GEOL250_ID|geology_GEO_NAME|geology_SHAPE_area|geology_SHAPE_len
1|5|0|0|6|5|Ybgg|0|0
2|1093|0|0|1094|1093|Kb|0|0
3|1118|0|0|1119|1118|Kp|0|0
4|537|0|0|538|537|Qp|0|0
5|1135|0|0|1136|1135|Km|0|0
}}}
Attributes will be transferred similarly to categories only if `layer` >
0.
