Referencing Object/Model field with dictionary key
I'm looping through a dictionary that has keys that match the fields in an ObjectModel
.
With the value from that dictionary, I query an address and gather some data that I want to then save in the Object
. My hope is to use the key from the dictionary to reference the field within the object.
I'm having a hard time explaining this with text so I hope the example code below showcases what I'm trying to do:
example_dict =
"key": "value",
"second_key": "second_value"
class ExampleModel(models.Model):
key = models.CharField(max_length=255)
second_key = models.CharField(max_length=255)
}
object_example = ExampleModel()
for key, value in example_dict:
data = doDataRequest(value)
object_example[key] = data
object_example.save()
python django python-3.x django-models

EDIT:
You were also trying to set an attribute of a class as if it were a dict, try to use built in methods such as getattr and setaddr to access those. Look here:
Visit https://docs.python.org/3.7/library/functions.html#setattr
I would recommend to try iterating differently on the dictionary, you could try something like this below, I think this is where your issue is coming in. If not let me know!
for key, value in example_dict.items():
data = doDataRequest(key)
//Use setattr
setattr(object_example, key, data)
And on another note, why use a dict for holding key value pairs if you are not using the value? perhaps try an array with your keys?
I was suggested to use the built-in functionsettattr
which seems to be working except for my DateTimeField is bugging out. As for the dictionary, I am actually using the value, it was a typo - I've since corrected it!

is USE_TZ=True in your settings.py?

If thats the case look into pytz and use the correctly formatted datetime object. There is a core django contributor who wrote this article, I attended his talk in San Diego and it was mind blowing. Visit: reinout.vanrees.org/weblog/2018/05/25/09-its-about-time.html

If you did not add the .items() in the for loop, that might be why date time is not working. Good luck :)
