QUESTION
At work, we're using EFCore on our data layer and graphql-dotnet to manage APIs requests, I'm having a problem updating some of our big objects using GraphQL mutations. When the user sends a partial update on the model, we would like to update on our database only the fields that actually were changed by the mutation. The problem we're having is that as we directly map the input to the entity, wheather some field was purposefully passed as null, or the field was not specified on the mutation at all, we get the property value as null. This way we can't send the changes to the database otherwise we would incorrectly update a bunch of fields to null.
So, we need a way to identify which fields are sent in a mutation and only update those. In JS this is achieved by checking if the property value is undefined, if the value is null we know that it was passed as null on purpose.
Some workarounds we've been thinking were using reflection on a Dictionary to update only the specified fields. But we would need to spread reflection to every single mutation. Another solution was to have a isChanged property to every nullable property on our model and change ir on the refered property setter, but... cmon...
I'm providing some code as example of this situation bellow:

On the mutation resolver instead of using GetArgument with my type, I'm using GetArgument and serializing it using JsonConvert.SerializeObject then by calling JsonConvert.PopulateObject I'm able to update only the fields that were informed.

AMOUNT = 1
x = 175
y = 175
def main():
screen = pygame.display.set_mode((600,600))
screen.fill( (251,251,251) )
BoxAmountCalc(humaninput)
DrawBoxCalc()
pygame.display.flip()
while True:
for event in pygame.event.get():
if event.type == QUIT:
return
def BoxAmountCalc(x):
x = (2**humaninput) * (2**humaninput)
size = 600/x
return size
def DrawBoxCalc():
while True:
pygame.draw.rect(screen,(0,0,0), (x,y,size,size))
AMOUNT += 1
x = x + size
x = y + size
pygame.display.flip()
if AMOUNT > humaninput:
break
ANSWER
Answered 2018-Feb-18 at 04:34Is this because I need it to be defined as a parameter for the function and then pass it into the function.
Yes. Once a function finishes executing, the variables created therein are destroyed. Here is an example:
