Re: [mapserver-users] RE Mapfile, EXPRESSION for CLASS >> NAME

2016-03-30 Thread Seth G 

Hi,

I had the same issue, but as an added complication the number of classes 
could change dynamically based on users adding and editing data.
I solved this by intercepting any web requests to this particular layer 
and using MapScript to build the classes on-the-fly, then passing the 
Layer object to generate the image.


for c in classes:
clsObj = mapscript.fromstring(c)
layer.classes.append(clsObj)

...


req = mapscript.OWSRequest()

req.loadParamsFromURL(querystring)

try:
dispatch_status = mymap.OWSDispatch(req)

#strip all the headers from the output as we add these through 
wsgi server


content_type = mapscript.msIO_stripStdoutBufferContentType()
mapscript.msIO_stripStdoutBufferContentHeaders()

resp = mapscript.msIO_getStdoutBufferBytes()
except Exception as ex:
logging.error(ex)
logging.error(querystring)
resp, content_type = str(ex), "text/plain"

return resp, content_type

If you have static, or rarely changing data, then it would be simpler to 
just use a script to build the classes once and save them as an INCLUDE 
to your MAP file. Python and Jinja2 (a templating library for Python) 
are handy for this.

Perhaps you can use CLASS TITLE instead of NAME

 [mapserver-users] Mapfile, EXPRESSION for CLASS >> NAME









All,

I think I’m trying to be too clever . . .

I have this MAPFILE chunk:

CLASS
COLOR 0 255 0
OUTLINECOLOR 0 0 0
   SIZE 10
   SYMBOL 'circle'
NAME '[FOLDERTYPE]'
TEXT '[FOLDERTYPE]'
   LABEL
 FORCE TRUE
 COLOR 255 255 0
 OUTLINECOLOR 0 0 0
 POSITION ur
TYPE TRUETYPE
FONT 'arial-bold'
SIZE 11
   END
 END


and I’m trying to use an Expression for the Label in the Legend graphic.  The 
FOLDERTYPE and is the two later code for map labels, while the FOLDERDESC is 
the long pretty name for the Legend.



Question, is it possible??  Ideas??  Before you say a separate class for each 
one, there are 120 FOLDERTYPEs in all, that would be a big, and hard to 
maintain Mapfile.

thanks

bobb
