Saving a Django form to a csv file - python

I have a Django form that is working fine. I'd like to save the data it submits to a CSV file. Is there a "best practice" way to do this?
I need to include blank fields in the CSV file where the user has not filled in a "required=False" field

You can find the document CSV File Reading and Writing very helpful for your problem.

I am creating a membership management system with Django. I need the staff to have the ability to upload excel files containing list of members (and their details) which I will then manipulate to map to the Model fields.

Any suggestions.
Thanks in advance
you can use xlrd to read excel files
in client side you just submit a form with file input.

How to store and download a zip file in database postgres

I'm trying to store and then download a zip file from Postgres database. I know that this is not the best approach (i should only save the path to file) but i need to do this way, just for learning and practice.
I did a python script to store the content of the file into a bytea field but this was not my final goal. I really want to know how to save the zip file.
Any ideas? I just know python so i'm trying to this in python
Thank you guys!
If you can store the file as a bytea field then storing a zipped file is just the same.
Postgres doesn't have a concept of "file" field - you simply store the content (as you did for the original content) in bytea field.
If you're asking about zipping a file on the fly,
Take a look at zlib it's one of the common modules for such tasks.

OpenERP 6.1 module with upload file field

I want to create OpenERP 6.1 module with a upload binary file field as one of the fields in view.
The file will be stored in database as binary data, but before storage in database I need to parse that file, and save data as part of the other created module.
So, I don't know how to specifiy filed for upload files in a view xml file, and also how to run the uploading process. Can somebody help me about this? Some code snippets or advice how to do that.
Take a look at the way the attachments module works, particularly the binary data column. You should also look at the screen definition.

How do I access PDF form fields with python

I need to automatically save pdf form fields to a database and write some of them later to new forms I am sending out. I can save the fields no problem but I don't know how to write to a PDF form field .. I am using pdf miner but I can't find anything in it to do this.
Can any one point me in the direction of a solution?
Reports labs has a open source PDF kit that let you write PDFs, including form fields http://www.reportlab.com. They also have commercial product the reads PDFs. But I've only used the open source version.
I've never used it, but people seem to like PyPDF
