Question

I have an application I am building using wxpython with postgresql as my database. I don’t know what is the right approach to send the data from GUI to the database but what I am doing is storing the GUI(txtctrl) output in dictionary and trying to send it to postgresql. My question is: Is there any way to send the data to the database using sqlalchemy where dictionary keys acts as the column_fields and dictionary-values as its values.Is there more elegant way to do the data-communication between GUI and database?

Answer 1

Supposing you are using declaratives in sqlalchemy, and your object name is Object, you can use:

# I suppose you already have your session somehow...
# If you want to add it to the database
# Assuming you did not change the __init__ method
obj = Object(**data_dictionary_with_keys_matching_column_names)
session.add(obj)

# If you want to issue an update
# obj is already there somehow...
for k, v in data_dictionary_with_keys_matching_column_names.iterkeys():
    setattr(obj, k, v)

session.commit()

That’s only if you are using the ORM and declarative. (You mentioned sqlalchemy, so I guess it does not change if it’s postgresql or another one)

EDIT: I think you are going for the right approach, just make sure you use wx.Validators for your forms and store in a dictionary the data, it’s very practical.
