[Qgis-developer] Layer comparision/suitability

[Jorge Tornero - Listas]

Hi,

I've developed a plugin in which the user has the ability to create a 
new layer with some certain fields (say, for instance, color, size, 
shape) or use and existing one, in that case the fields can be added to 
the layer.

I have implemented a "brute force" comparision: I check in the existing 
layer for the existence of those fields and of the same type. You could 
see how in this gist:

Unfortunately, it doesn't seem to work very well at all. I wonder if 
someone has faced this problem before or could suggest another approach.

Thank you very much.

All the best,

Jorge
