I have been working on this for who knows how long but I have two functions: one that is activated through ipywidgets special event and the next that is called within the first function.
function number one:
def lipas_button_clicked(b):
'''
Def used to select and fetch dataframe from LIPAS
------------------------------------------------------------
PARAMETERS
- b <button default>
RETURNS
- Automatic append of selected YKR IDs <list element> (global variable)
- Message in display
'''
code = str(select_lipas.value)
lipas = GetLipasData(code)
return print(lipas)
function number two:
def GetLipasData(typecode):
code_list = [typecode]
lipas = pd.DataFrame()
for x in code_list:
typecode = x
r = requests.get("""http://lipas.cc.jyu.fi/api/sports-places?fields=type.name&fields=location.sportsPlaces&fields=location.geometries&fields=name&fields=type.typeCode&fields=location.locationId&fields=location.city.name&fields=location.postalCode&fields=location.address&typeCodes=""" + typecode + """&cityCodes=91""").json()
df = pd.json_normalize(r, record_path=['location', 'geometries', 'features'], meta=[['location', 'sportsPlaces'], ['location', 'address'], ['location', 'postalCode'], ['name']])
df['typeCode'] = typecode
lipas = lipas.append(df)
return lipas
Whenever I run this code using the widgets button the first function returns an empty dataframe to me. However, when I call the second function like this:
# example typecode
temp = '1120'
lipas = GetLipasData(temp)
print(lipas)
The function works and I end up with the desired dataframe. Here is a snippet of the dataframe:

I cannot for the life of me understand why calling the same function through the ipywidgets event does not work. Here is the code for the ipywidgets.
# adding the Select widget. Select means that you can select the correct one.
select_lipas = widgets.Select(placeholder='Valitse palvelu(t)',
options=lipas_options,
layout = {'width':'max-content'},
ensure_option=True,
disabled=False)
# adding the button widget. Click Me Tooltip is an action which run after clicking on the button.
b = widgets.Button(description='Valitse LIPAS palvelu',
disabled=False,
button_style='info',
tooltip='Click me',
icon='check')
# adding the click event to the button. To add event you do it as a function
b.on_click(lipas_button_clicked)
Any ideas? Please let me know if more information is required. Much appreciated for any help in advance!
UPDATE:
I was using AppLayout() to display my widgets and for whatever reason this was not sending the selected code back to my functions. I tested it out by switching back to displaying each widget separately and it worked immediately. Any ideas on the difference?
This is a typical problem with on_click.
You are returning an object at the end of the function, but it is not possible to assign it to a variable in the main namespace. You need the lipas_button_clicked function to have a side effect, not return a value.
One way around this is to create a global variable, and within your lipas_button_clicked function, instead of returning the data from your GetLipasData function, assign it to that global variable. It will then be accessible from outside your lipas_button_clicked function.

I have been trying to write to a database and am having trouble setting data using two different classes in the one function.
Firstly, all values are being passed through a GUI and in this case, only the following entries were passed: 'Categories' = C, 'Usage' = Charter, 'DispTHR' = 5000.
Here you can see that I have two classes I am wanting to access (airport and runway) where the function set_opsdatabase_details() will go to the appropriate class and write to our database. This is all well and good when the airport and runway are separate from each other; however, when integrating them in the same function I can't seem to get the corresponding airportvalueDict = {} and runwayvalueDict = {] to display the values I want. Could someone help me understand how to write the correct entry box values into the corresponding valueDict dictionaries?
Thank you in advance! (a screenshot of the output from the print statements is attached)

Lets say I have an assembly like this:
MainProduct:
-Product1 (Instance of Part1)
-Product2 (Instance of Part2)
-Product3 (Instance of Part2)
-Product4 (Instance of Part3)
...
Now, I want to copy/paste a feature from Product3 into another one.
But I run into problems when selecting the feature programmatically, because there are 2 instances of the part of that feature.
I can't control which feature will be selected by CATIA.ActiveDocument.Selection.Add(myExtractReference)
Catia always selects the feature from Product2 instead of the feature from Product3. So the position of the pasted feature will be wrong!
Does anybody know this problem and has a solution to it?
Edit:
The feature reference which I want to copy already exists as a variable because it was newly created (an extract of selected geometry)
I could get help else where. Still want to share my solution. It's written in Python but in VBA its almost the same.
The clue is to access CATIA.Selection.Item(1).LeafProduct in order to know where the initial selection was made.
import win32com.client
import pycatia
CATIA = win32com.client.dynamic.DumbDispatch('CATIA.Application')
c_doc = CATIA.ActiveDocument
c_sel = c_doc.Selection
c_prod = c_doc.Product
# New part where the feature should be pasted
new_prod = c_prod.Products.AddNewComponent("Part", "")
new_part_doc = new_prod.ReferenceProduct.Parent
# from user selection
sel_obj = c_sel.Item(1).Value
sel_prod_by_user = c_sel.Item(1).LeafProduct # reference to the actual product where the selection was made
doc_from_sel = sel_prod_by_user.ReferenceProduct.Parent # part doc from selection
hb = doc_from_sel.Part.HybridBodies.Add() # new hybrid body for the extract. will be deleted later on
extract = doc_from_sel.Part.HybridShapeFactory.AddNewExtract(sel_obj)
hb.AppendHybridShape(extract)
doc_from_sel.Part.Update()
# Add the extract to the selection and copy it
c_sel.Clear()
c_sel.Add(extract)
sel_prod_by_catia = c_sel.Item(1).LeafProduct # reference to the product where Catia makes the selection
c_sel_copy() # will call Selection.Copy from VBA. Buggy in Python.
# Paste the extract into the new part in a new hybrid body
c_sel.Clear()
new_hb = new_part_doc.Part.HybridBodies.Item(1)
c_sel.Add(new_hb)
c_sel.PasteSpecial("CATPrtResultWithOutLink")
new_part_doc.Part.Update()
new_extract = new_hb.HybridShapes.Item(new_hb.HybridShapes.Count)
# Redo changes in the part, where the selection was made
c_sel.Clear()
c_sel.Add(hb)
c_sel.Delete()
# Create axis systems from Position object of sel_prd_by_user and sel_prd_by_catia
prod_list = [sel_prod_by_user, sel_prod_by_catia]
axs_list = []
for prod in prod_list:
pc_pos = pycatia.in_interfaces.position.Position(prod.Position) # conversion to pycata's Position object, necessary
# in order to use Position.GetComponents
ax_comp = pc_pos.get_components()
axs = new_part_doc.Part.AxisSystems.Add()
axs.PutOrigin(ax_comp[9:12])
axs.PutXAxis(ax_comp[0:3])
axs.PutYAxis(ax_comp[3:6])
axs.PutZAxis(ax_comp[6:9])
axs_list.append(axs)
new_part_doc.Part.Update()
# Translate the extract from axis system derived from sel_prd_by_catia to sel_prd_by_user
extract_ref = new_part_doc.Part.CreateReferenceFromObject(new_extract)
tgt_ax_ref = new_part_doc.Part.CreateReferenceFromObject(axs_list[0])
ref_ax_ref = new_part_doc.Part.CreateReferenceFromObject(axs_list[1])
new_extract_translated = new_part_doc.Part.HybridShapeFactory.AddNewAxisToAxis(extract_ref, ref_ax_ref, tgt_ax_ref)
new_hb.AppendHybridShape(new_extract_translated)
new_part_doc.Part.Update()
I would suggest a differed approach. Instead of adding references you get from somewhere (by name probably) add the actual instance of part to selection while iterating trough all the products. Or use instance Names to get the correct part.
Here is a simple VBA example of iterating one lvl tree and select copy paste scenario.
If you want to copy features, you have to dive deeper on the Instance objects.
Public Sub CatMain()
Dim ActiveDoc As ProductDocument
Dim ActiveSel As Selection
If TypeOf CATIA.ActiveDocument Is ProductDocument Then 'of all the checks that people are using I think this one is most elegant and reliable
Set ActiveDoc = CATIA.ActiveDocument
Set ActiveSel = ActiveDoc.Selection
Else
Exit Sub
End If
Dim Instance As Product
For Each Instance In ActiveDoc.Product.Products 'object oriented for ideal for us in this scenario
If Instance.Products.Count = 0 Then 'beware that products without parts have also 0 items and are therefore mistaken for parts
Call ActiveSel.Add(Instance)
End If
Next
Call ActiveSel.Copy
Call ActiveSel.Clear
Dim NewDoc As ProductDocument
Set NewDoc = CATIA.Documents.Add("CATProduct")
Set ActiveSel = NewDoc.Selection
Call ActiveSel.Add(NewDoc.Product)
Call ActiveSel.Paste
Call ActiveSel.Clear
End Sub
I have many aggregations of the type below in my code:
period = 'ag'
index = ['PA']
lvl = 'pa'
wm = lambda x: np.average(x, weights=dfdom.loc[x.index, 'pop'])
dfpa = dfdom[(dfdom['stratum_kWh'] !=8)].groupby(index).agg(
pa_mean_ea_ag_kwh = ('mean_ea_'+period+'_kwh', wm),
pa_pop = ('dom_pop', 'sum'))
It's straightforward to build the right hand side of the aggregation equation. I want to also dynamically build the left hand side of the aggregate equations so that 'dom', 'ea', 'ag' and 'kw/kwh/thm' can be all created as variable inputs and used depending on which process I'm executing. This will significantly reduce the amount of code that needs to be written and updates will also be easier to manage as otherwise I need to write separate otherwise identical code for each combination of the above.
Can I use eval to do this? I'd appreciate guidance on how to do it. Thanks.
Adding code written after feedback from Vaidøtas I.:
index = ['PA']
lvl = 'pa'
fname = lvl+"_pop"
b = f'dfdom.groupby({index}).agg({lvl}_pop = ("dom_pop", "sum"))'
dfpab = exec(b)
The output for the above is a 'NoneType object'. If I lift the text in variable b and directly run the code as show below, I get a dataframe.
dfpab = dfdom.groupby(['PA']).agg(pa_pop = ("dom_pop", "sum"))
(I've simplified my original example to better connect with the second code added.)
Use exec(), eval() is something different
For example:
exec(f"variable_name{added_namepart} = variable_value{added_valuepart}")
I am currently working on a little script that creates a crane-like rig automatically in Autodesk Maya, the user gets to choose the amount of joints by a UI.
My question is how do I take the integer input of the user and use it as the variable value for my "jointAmount"?
I am also wondering how I would be able to call my function(AutoCraneRig) to actually run the script from the UI. I have a "apply"-button but I am unsure how to connect it to my function.
I have seen similar posts like mine but I feel that the solutions shown are somewhat hard for me to understand and/or I can't really relate what is shown to my own problem.
If anything is unclear or more information is needed from me please don't hesitate to call me out.
Here is what my current UI look like
import maya.cmds as cmds
import pymel.core as pm
def jntctrl():
number = pm.intField(jnt, q=1, v=1)
print(number)
if pm.window("stuff", exists = True):
pm.deleteUI("stuff")
pm.window("stuff", t = "Crane Rig Generator", w=400, h=200)
pm.columnLayout(adj = True)
pm.text(label="Joint Amount:")
jnt = pm.intField(changeCommand = 'jntctrl()')
pm.button(label="Create Crane")
pm.showWindow()
#Defining how many joints the user want to have for their crane rig
jointAmmount = 5
#Defining how many controllers the user want to have to orient the crane.
#May not exceed the joint amount
controllerAmount = 5
def autoCraneRig():
#Creating the joints
for i in range(jointAmmount):
pm.joint()
pm.move(0, i, 0)
#Creating the controllers
for i in range(controllerAmount):
pm.circle()
pm.rotate (0,90,0)
pm.makeIdentity (apply= True)
#Creating the groups
for i in range(controllerAmount):
pm.group()
#Somehow one of the nurbs get parented to a group when running the script, here i select both the groups and then unparent them.
pm.select("group*", "nurbsCircle*")
pm.parent(world = True)
#Creating lists/dictionaries for the groups
#Since I wanted to parent my objects by their number I had to put all objects in lists/dictionries to get access.
groups = pm.ls('group*')
nbs = [int(n.split('group')[-1]) for n in groups]
groupDic = dict(zip(nbs, groups))
#Create a list/dictionary for the joints
joint = pm.ls('joint*', type='joint')
nbs = [int(n.split('joint')[-1]) for n in joint]
jointDic = dict(zip(nbs, joint))
common = list(set(groupDic.keys())&set(jointDic.keys()))
#Parenting the groups to the joints
for i in common:
pm.parent(groupDic[i], jointDic[i])
#Reseting the transformations of the groups and then unparenting them to still have the transformation data of the joints
pm.select("group*")
pm.makeIdentity()
pm.parent(world = True)
#Creating a list/dictionary for the nurbs aswell that will be parented to the groups in numeric order
nurbs_sh = pm.ls('nurbsCircle*', type='nurbsCurve')
#I had to get the transformation information from the nurbs before parenting them with anything would work(took a long time to get it right).
nurbs_tr = pm.listRelatives(nurbs_sh, p=1)
nbs = [int(n.split('nurbsCircle')[-1]) for n in nurbs_tr]
curveDic = dict(zip(nbs, nurbs_tr))
common = list(set(groupDic.keys())&set(curveDic.keys()))
#Parent the nurbs to the groups
for i in common:
pm.parent(curveDic[i], groupDic[i])
#Select the nurbs and reset transformations and then freeze transform
pm.select("nurbsCircle*")
pm.makeIdentity()
#Orient constrain the controllers/nurbs to the joints
for i in common:
pm.orientConstraint(curveDic[i], jointDic[i])
#Parent the 2nd group with the first controller. Do this for the whole hierarchy.
for i in common:
pm.parent(groupDic[i+1], curveDic[i])
#I'm getting keyError after I put the "+1" in my groupDic and I don't know why, although it still works, I guess.

Here's an example for how to call a specific function/command when a button is clicked, and how to get the value of an int field. The key is in naming the fields, so you can reference the UI control later.
import pymel.core as pm
def ui():
if (pm.window("myWindow", exists=True)):
pm.deleteUI("myWindow")
window = pm.window("myWindow", t="My Window", w=400, h=200)
pm.columnLayout(adj=True)
pm.intField("myIntField")
pm.button("Button", aop=True, command="action()")
pm.showWindow(window)
def action():
print("Button clicked!")
value = pm.intField("myIntField", q=True, v=True)
print(value)
ui()

I want to change (kind of dynamically) the NumberOfColumns of a rowColumnLayout inside a Maya Window. Depending on the value given by 'SLiBThumbSizeComboBox' i want to change the count for the columns.
Here is the problem: when running my 2 functions inside the Script Editor everything is working fine. I execute the first one - the ScrollLayout is created. I execute the second and the rowColumnLayout is created with the right count of columns.
But when I try run it only by the first function, meaning the second function is called at the end of the first one - it's not working anymore?! I get the error message, that NumberOfCollumns has to be greater than 0 ?!
def FunctionA():
if cmds.scrollLayout('SLiBScrollLayout', query = True, exists = True):
cmds.deleteUI('SLiBScrollLayout', layout = True)
cmds.scrollLayout('SLiBScrollLayout', p="SLiB_thumbsframe")
def FunctionB():
iconLayout = cmds.optionMenu('SLiBThumbSizeComboBox', query = True, value = True)
iconSize = iconLayout.split('x')
iconDiv = int(iconSize[0])
n = int(cmds.scrollLayout("SLiBScrollLayout", query=True, saw=1)/iconDiv)
cmds.rowColumnLayout('Icons', numberOfColumns=n, p="SLiBScrollLayout")
Thanks in advance

I'm not surprised the rowColumnlayout complains if you give it zero columns: you'll always need 1. Depending on how the are setting up the gui , your query on saw might return 0, which would explain your problem.
Here's a very basic example of what it looks like your trying to do:
w = cmds.window()
c = cmds.columnLayout(adj=True)
v_slider = cmds.intSlider(min = 1, max =10, value=2)
h_slider = cmds.intSlider(min = 1, max =10, value=2)
scroll = cmds.scrollLayout()
form = cmds.formLayout()
def update_row(*_):
# get the row and column counts
rows = cmds.intSlider(v_slider, q=True, v= True)
columns = cmds.intSlider(h_slider, q=True, v= True)
# delete the old layout and rebuild.
# the 'or []` below lets you loop even if there are no children....
for n in cmds.formLayout(form, q=True, ca=True) or []:
cmds.deleteUI(n)
cmds.setParent(form)
# make a new rowColumn
new_row = cmds.rowColumnLayout(nc = columns)
for n in range(rows * columns):
cmds.button(label="button_%i" % n)
cmds.formLayout(form, e=True, af = [(new_row,'top',0), (new_row, 'bottom', 0 ), (new_row, 'left', 0 ), (new_row, 'right', 0)])
# both sliders call the update function
cmds.intSlider(h_slider, e=True, cc =update_row)
cmds.intSlider(v_slider, e=True, cc =update_row)
update_row() # do it once to get started
cmds.showWindow(w)
The key here is the order in which it's declared: the function knows what v_slider, h_slider and form are because it's declared after them and doesn't need to do extra work to find them (you can get a more controlled version of the same effect with a class. You'll notice I don't use the names at all: names are unreliable if there's an old layout lying around, it's simpler to use variables.
I've also set the minimum values for the row and columns to 1 so there's no zero division problem.
