Referencing Object/Model field with dictionary key










0















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()

          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 function settattr 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!
