Nevermind, that return line should work. The self.Branches and
self.Nodes are variables containing the strings for your dict.
The problem is in the AlgorithmDialog code. Hope someone else can help
you with that.
Cheers,
Raymond

Hi Bjorn,
What do you expect this
{self.Branches:dest_id,self.Nodes:dest_id2}
would result in? It doesn't look like python to me but I might be
missing something.
What does the variable self.Branches contain?
"self" Refers to your Branches_Nodes class itself.
(By the way, it is a good habit to start variable names with a lower
case character.)
Regards,
Raymond

Dear QGIS community,
In the spirit of open-source I am trying to convert a set of scripts
that ive designed in ArcMap to QGIS 3.x. I hope that this will enable
a broader community of individuals to use the workflows ive designed.
The original scripts can be found at
https://github.com/BjornNyberg/NetworkGT/tree/master/Scripts
My problem is that in my first attempt to convert the scripts, QGIS
either crashes or gives the following error.
2019-01-30T16:51:27 WARNING Traceback (most recent call last):
File
"C:/PROGRA~1/QGIS3~1.4/apps/qgis/./python/plugins\processing\gui\AlgorithmDialog.py",
line 238, in on_complete
self.feedback.pushInfo(self.tr('Execution completed in
{0:0.2f} seconds').format(time.time() - start_time))
NameError: free variable 'self' referenced before
assignment in enclosing scope
I have established that this error occurs at the very end of the
script when calling ' return
{self.Branches:dest_id,self.Nodes:dest_id2}'. I do not believe that I
have explicitly defined self anywhere in the processAlgorithm
function itself. The algorithms themselves work as intended and the
shapefiles are created before the program crashes.
I am not a programmer by trait so I'm not entirely sure how to problem
solve this error and any help would be most appreciated. I can also
provide a test dataset if that is helpful.
Cheers,
Bjorn
